Hachinan tte, Sore wa Nai Deshou! Volume 10 Chapter 10 part2

“We have confirmed the capitulation of the rebel army at the front.”

“Again? That's too quick, isn't it?”

“I think it's only natural. There's no point in splitting military forces right now. After all they would turn into nothing more than targets for getting individually crushed. Duke Nürnberg should be gathering his whole army at his stronghold.”

◆◇◆◇◆

With Peter as supreme commander, the imperial army invaded Nürnberg Dukedom for a second time.
The advance was progressing well, but this was owed to it never turning into a battle.
We also continued to advance while only working on sending the disarmed troops and nobles, who surrendered or abandoned Duke Nürnberg, to the rear.

“Our job only consists of the disarming of the groups that surrendered and the procedures to transfer them to the rear, right?”

“We will be given a warm welcome at the end of it all.”

“That's true, isn't it? I believe they are ready and waiting for us at their stronghold. Besides, Duke Nürnberg hasn't counted on the lot that surrendered from the very start. Rather, if he can get them to surrender, Peter-dono's burden will increase.”

“After all it would be wrong of us to kill the prisoners.” (Haruka)

“That's how it is, Mrs. Haruka.” (Christoph)

“I-I still haven't gotten married officially!” (Haruka)

“By now it's probably just a matter of time. It's not something you have to get embarrassed about, is it?” (Christoph)

“That's true, but…” (Haruka)

◆◇◆◇◆

The royal army was skillfully put to use by Philip and Christoph.
Erw and Haruka had become a lot more used to leading military forces. They are chatting while dealing with the escort of the enemy soldiers that capitulated. It's to the extent that Christoph, who's good at this kind of work, has enough time to tease Haruka who's engaged to Erw. It's the same for Philip as well, but if this person hadn't been born into the Margrave Browig family, there wouldn't have been any reason for him to act so unsightly in the dispute.

“Wendelin, are thou brooding over something?” (Therese)

“Just a bit. At any rate, there's no need for you to especially come along on this campaign, is there?” (Wendelin)

“I'm well aware that I'm a bother, but I have to make sure with my own eyes. Duke Nürnberg's…no, Max' death.” (Therese)

There was another person with a guilty conscience that had joined the royal army.
It's Therese who had retired as Duchess Philip.
Naturally her desire to participate was met with some doubts by Peter and his retainers.

『You are going to participate in this? Don't you think that it will cause unnecessary suspicions?』 (Peter)

It was his usual tone, but even Peter didn't smile.

『What's the reason, Therese-sama?』(Emera)

『As someone who was concerned with this civil war, I must ascertain it to the very end with my own eyes.』 (Therese)

『What is it that you have to ascertain?』 (Emera)

『That's obvious. The moment of Duke Nürnberg's death.』 (Therese)

Even Emera, who usually doesn't change her expression much, couldn't hide her surprise due to Therese's reply.

『No matter what reason he might have, there's no room to take extenuating circumstances into consideration with Duke Nürnberg. There's no other option for that man but to die. That guy being the person with whom I associated the longest is because I don't have anyone to call friend. It's something I have to see through.』 (Therese)

『I see. Does Duke Nürnberg have no friends either? Even a Duke by birth has it difficult, huh?』(Peter)

Peter is a commoner prince that had no expectations placed on him by anyone from the start, but because of that he had many friends in the same circumstances as him. They are supporting the current Peter and thus he is a person exactly opposite to Duke Nürnberg. Even though Duke Nürnberg has retainers, who he has assigned to responsible posts, and nobles, who share the same ideas as he does, he apparently didn't have a single friend.

『So the same as Wendelin, huh?』 (Peter)

『I do have friends!』 (Wendelin)

Peter, that rude fellow. Even I have at least some friends!

『Ascertaining Duke Nürnberg's death with your own eyes, eh…?』

『Once that's finished, I won't meddle any further in the politics of the Empire.』 (Therese)

『…Understood. I shall permit it. Let's have you come along as mysterious female soldier Therese.』 (Peter)

In the end Peter gave his authorization and Therese joined the royal army as normal soldier.
It not being the imperial army indicated her complicated position.
The march of the imperial army's main unit led by Peter is proceeding well. The entire Empire fell under Peter's control in less than a month.

“Well, except for that underground fortress where Duke Nürnberg and his men have holed themselves up.” (Burkhart)

Burkhart-san says while looking at the mountain area located next to Duke Nürnberg household's mansion which we finally occupied. As a matter of fact, there was a military fortress from the era of the Ancient Magic Civilization in the underground of this mountain area. Large-scaled defense facilities had been left behind in an usable state. According to the retainers we caught, Duke Nürnberg apparently obtained various magic tools through the excavation of that underground fortress.

“He has abandoned all territory and military bases. I guess he plans to gain time by secluding himself in there.”

“This might take some time,” Erw sighed.

“The main defense facility is of course an underground ruin.”

The several ten thousand elites that had been carefully selected by Duke Nürnberg have holed up themselves in the underground stronghold from the era of the Ancient Magic Civilization while possessing large quantities of food and goods.
I learned that it will be harsh for the attacking side if they don't at least possess three times the numbers of the defending side. The number of soldiers on our side are exceeding theirs by more than three times, but one can't deny that the imperial army is an assembly of various kinds of troops. Above all, it's very likely that the enemy still owns some magic tools that can be turned into weapons.
Burkhart-san predicted that it would turn into a difficult battle.

“Do you have an ingenious idea, Peter?” (Wendelin)

“First, a standard siege that doesn't allow even an ant to get through…ha, that's impossible though!” (Peter)

Since the defense facilities use the underground ruins in the mountain area, they should be able to escape through some hole as long as we don't surround them with quite a large army. On a first glance the population of Nürnberg Dukedom is awfully submissive towards the invaders but they have likely formed an underground organization that secretly provides Duke Nürnberg's army with provisions and information.

“How troublesome…in case we eliminate those resistance forces, we will mistakenly end up killing innocent residents…”

Even the residents that had been obedient towards Peter and the others so far might oppose them then.
If we make enemies out of a great number of people living in the Nürnberg Dukedom, the superiority of Peter, who had finally managed to assemble a big army, will vanish in an instant.

“As long as you limit it to military affairs, Duke Nürnberg is definitely a genius.” (Ina)

I guess Ina's assessment is correct. Although it's for the sake of surviving, it looks like he doesn't consider the future overly much.
After all Nürnberg Dukedom will fall into ruin all the more, the longer this drags on.

“But, dear, if we butt in too much…” (Elise)

“I guess you're right there…” (Wendelin)

The civil war is in its final phase. Once Duke Nürnberg is defeated by Peter, it will be the end. Us, as foreigners, taking center stage in such atmosphere is not smart.
Meaning, it's fine as long we just participate.
As it's the same with the Earl Mizuho Country's army, they fell back to the rear as they already obtained plenty of military achievements in the capital defense battle.

“Our encampment is next to that of the Mizuho army.”

Given that Peter's victory is pretty much set in stone, there are many nobles and soldiers, who are full of spirit to gain rewards as compensation for their war expenditures, additional territory, a higher peerage and high-ranking positions in the government by earning achievements in the attack against the underground fortress where Duke Nürnberg is hidden.
Outsiders like us will observe from the rear while leaving it to them.
Once we set up camp at the location assigned to us by Peter, a messenger from the neighboring Mizuho army visited us.

“Excuse me! Our Lord wishes to invite Earl Baumeister-sama's party for dinner.”

“Please tell him that we will gladly accept the invitation.” (Wendelin)

He's probably asking about taking a meal since both of us have time to spare.

◆◇◆◇◆

“Therese-dono, you don't look very disappointed, do you?”

“I became free. Let alone being displeased about that, I think that it's great.” (Therese)

“The emperor's throne doesn't give any happiness, huh?”

“After all that throne has been made out of thorns.” (Therese)

Therese doesn't mind High Earl Mizuho having changed allegiance to Peter. In return High Earl Mizuho doesn't mention the matter of Therese not having removed the previous emperor either. After all those are already matters of the past.

“Oh my, how beautiful.”

“I guess there's also food that you enjoy by looking at it.”

Katharina and Burkhart-san had their eyes sparkle due to the luxurious cuisine one wouldn't expect to appear on a battlefield. Mizuho's hospitality was an extravagant, traditional Japanese meal brought in courses.
Although that's not something one would consider to do during a war, the probability of Duke Nürnberg leaving his underground fortress to stage an attack is almost non-existent and thus it probably poses no problem.
This kind of cuisine I only ate at a high-class restaurant where my company performed its business entertainment in my previous life. With my salary back then, well, it was a meal well outside of my range.

Appetizer: Tofu, Abalone, Sweet Coltsfoot, Bean-curd lees.
Supper: Sea bream in tofu skin, grilled mullet roe, hen-of-the-woods.
Sashimi: Black tuna, squid, flounder, prawn, blood clam.
Hassun: Common clam, mizuna, dipped garden eel, bamboo shoot with pepper stir-fry, stewed sardine, kelp with herring roe.
Flame-broiled: Mackerel pickled in sweet miso, Fuki flower buds.
Boiled dishes: Small turnip, fish liver and eggs in tea cloth, cabbage, taro cormel.
Pickled dishes: Halfbeak, red turnip, wood jellyfish.
Main dish: Matsutake rice.
Finishing supper: Red miso soup.
Pickled vegetables: bok choy, chopped vegetables pickled in salt with red shiso leaves.
Dessert: Soft sweet bean jelly, pear, powdered green tea.
(T/N: Don't ask me to explain all of these… pwease…)

A menu, which had the various dishes listed with a writing brush on paper that was similar to Japanese paper, was placed on the table. Young, uniformed Mizuho soldiers served as waiters. Since it's this kind of job, all of them are ikemen.
Even so, there are many dishes with the same name as in Japan, aren't there…?

“It's delicious.” (Katharina)

“How magnificent.”

“It's tasty, but I would be happy if the portions were a bit bigger.” (Wilma)

“I think so as well! I'm also at the point where I want some wine!” (Armstrong)

Ina and Luise honestly enjoyed the various dishes, but for Wilma the portions are too small. It will probably be bad if she doesn't eat something later on when we get back to our own camp.
Doushi threw a tantrum as he wanted some alcohol.

“Uncle-sama, this is a battlefield. You will have to wait until the battle's over.” (Elise)

“Guuuhh…what disappointment.” (Armstrong)

I think that it's usually the other way around, but Doushi got chided by Elise, his younger niece.

“Cheers on becoming a free woman, Therese-dono. Earl Mizuho Country has to get involved in the Empire's politics from now on as well. That will only increase the troubles.”

“There's still another trouble remaining.” (Therese)

Therese gave High Earl Mizuho, who was lamenting over the coming difficulties after the civil war ended, a short warning.

“As expected, it's going to be a tough battle, huh?”

“It's not like Duke Nürnberg was imprisoned in the underground fortress. He secluded himself in there out of his free will. The number of his forces has dwindled a lot, but the remaining troops are his true elites. If those aiming for military achievements charge in without thinking, the number of casualties will only grow unnecessarily, I think.” (Therese)

Therese's prediction came true on the next day.

◆◇◆◇◆

“They got defeated when they attacked to have a look at the situation.”

“That's a disaster, isn't it? Oh well, isn't it fine as long as we win in the end? Therefore, do your best.”

“Eh—-! That's your reaction here?”

◆◇◆◇◆

When I believed it to be strangely noisy last night, Peter had apparently launched a night raid using a part of his military forces.
The next morning Peter showed up as all of us were grilling the food we had received from High Earl Mizuho over earthen charcoal braziers and open fires as substitute for breakfast.

“I guess all's within assumption?” (Therese)

“Uuh, it's awkward with Therese-dono here…” (Peter)

“Therefore, Wendelin, there are ambitious people scheming to oppose Peter-dono by using the achievements of defeating Duke Nürnberg after the war, but all of them have been simply eliminated by taking advantage of the battle as they were idiots who charged against an underground fortress without any kind of plan. It's not something at the level thou would need to care about.” (Therese)

“What a frightening story.”

That means Peter got rid of potential enemies by making use of the battle.

“It's fine for thee to not concern yourself with such matters, Wendelin. This fish called saury is delicious with the oil sticking to it. It goes really well with this grated daikon and this citrus. Saury is a native product limited to Nürnberg Dukedom.” (Therese)

“Therese, that's a native product of Philip Dukedom. Though it has been caught by Mizuho fishers.”

“I know. That was a light joke.” (Therese)

Therese said something similar to what a daimyo would say in a Japanese rakugo while eating the grilled saury.

“I wonder whether the chestnuts finished roasting?” (Wendelin)

“Wend, they are done.”

“However, freshly roasted chestnuts are dangerous!” (Armstrong)

“Really? If you peel them like this…”

Luise clad her fingers with a very thin film of mana and completely peeled the just roasted chestnuts in an instant.
If it was an ordinary person, they would burn their fingers. Peeling them down to their thin skin is difficult.
Because Luise is a martial arts expert, she can do that.

“You are amazing, Luise. And the roasted chestnuts are delicious.”

“Hehe, I got praised by Wend. Roasted chestnuts are tasty, aren't they?” (Luise)

Everybody enjoyed the roasted chestnuts that had been quickly peeled by Luise.

“Dear, I will later prepare Mont Blanc and marrons glaces. Nonetheless, the new chestnuts are great.” (Elise)

“Elise-sama, I will make sweet chestnut bean jelly and chestnuts in red bean soup later on.” (Haruka)

“Those certainly sound delicious as well.”

“Wend, the potatoes finished roasting. The new potatoes are sweet and tasty.”

“Potatoes are great too, aren't they?”

“Such irregular breakfast at times is nice.”

We noisily grilled various ingredients and enjoyed the food together.

“Say…have you all listened to what I said?” (Peter)

I did, but I didn't expect the imperial army to become unable to continue their operation due to the mindless acts of incautious nobles. I don't think that it's necessary for us to help out either.

“Even if us foreigners made a move here, we would be very likely told to not do anything unnecessary. The saury is delicious, but I really need booze to go with this.” (Burkhart)

“Burkhart-san, for better or worse we are still in a war.” (Ina)

“Injou-chan, you are too serious. Ah, I wonder whether I won't get a vacation soon.” (Burkhart)

Burkhart-san said it in my place, but that's how it is. Please do your best with just the imperial army.

“Don't say that…”

◆◇◆◇◆

————————— End of Part 1 —————————–

“Oh, isn't this Earl Baumeister-dono? If you are here to treat the injured, that's already done.”

“Really?”

“For even Elise-dono to expressly come here. Sorry. Since we have received assistance from the churches of both denominations, we have enough healing magicians at hand.”

Once we headed to the imperial army's headquarter, 『Mister Baron』, who had become a real Baron after receiving the territory and peerage from Peter, greeted us. The healing of our injured allies apparently had already been finished by Mister Baron and those below him, as well as the healing magicians dispatched by the churches. There were only casualties among the troops of the nobles who hurried to obtain military exploits. The imperial army under Gilbert's command is completely unhurt and not disturbed at all.
I wonder whether there's anything for us to do in this situation.

“It's because it's an underground fortress that uses a mysterious underground ruin. The one defending it is that Duke Nürnberg and of course there were traps as well.”

A great number of sharp fangs had been installed at the fortress.
Smaller versions of the devices that spit out the breath magic, which had been equipped on the previous dragon golems, had been set up at various places. The nobles, who staged a night raid in a dark place with bad visibility, apparently ended up suffering from those all together.

“Since I predicted that such weapons might be there, I wondered if we can break them through a firefight with the magic guns and asked the magician unit and High Earl Mizuho, but…”

However, that wasn't Duke Nürnberg's only trump card.
“Just when we tried to have a part of the magicians attack the breath-generating devices as test, the spells were blocked by a magic barrier,” Peter says.

“Our movements are completely visible for the other side. Our attacks are thwarted by the magic barrier and then the barrier gets lifted and we are attacked by the breath-generating devices. At this point it's a complete stalemate.” (Peter)

“Wouldn't it be better to let the magicians handle it?”

“You know, the number of our magicians has fallen considerably.”

The empire lost many magicians in the civil war. It's already at the point where no one complains about Emera, who would have originally been told that she's not qualified due to her young age, becoming the head magician. That's how serious the lack of magicians had become.

“Having said that, that magic barrier won't get destroyed even when I, who has almost the same amount of mana as Emera, fire a spell? Then it will be doubtful whether Wendelin-san and Doushi can break it, too.” (Katharina)

It's as Katharina says. The target is an inheritance of the Ancient Magic Civilization, so…
Even Peter shouldn't view the information so optimistically to believe that it will be somehow solved as long as Doushi and I fire spells at full power.

“What about Mizuho's magic guns?”

“High Earl Mizuho said that they might not be able to penetrate the barrier as they lack fire power…”

Suddenly there's a big explosion and right after that I felt with my skin how the air's vibrating.
The Mizuho army probably fired their magic guns against the magic barrier.

“… Looks like it was a failure.”

A few minutes later a message from High Earl Mizuho that the mission had failed reached us.

“Is there no other hand to play?”

“Your Highness, let's surround them with the large army and wait until they run out of provisions.”

“That's impossible.”

First off, as heard before, it's not possible to completely besiege them, even with a big army, as the underground fortress is too huge.
Not all of the local residents are loyal to the Empire either. It's very unlikely that Duke Nürnberg hadn't formed an underground organization to secretly bring news and food into the fortress.

“Even if only food is brought in, it should be possible for them to hole up there for many years to come. That's the reason why he only kept his elites around.”

By making the other nobles and troops surrender, he succeeded in pushing their food consumption on the Empire.

“If the imperial army continues to mobilize a large army, it will waste money and food. On the other hand, if we draw back here without putting things to an end, Duke Nürnberg will recover his territory after leaving the underground fortress.”

“Isn't that no good? We won't be able to win, will we?”

I didn't expect that the capture of Duke Nürnberg would turn into such a pain in the ass.

“We can win as long as we destroy that magic barrier.”

I see. As the fortress is too huge, the troops of Duke Nürnberg can't defend all of it at the moment, can they?
If the imperial army invaded from various places, even Duke Nürnberg would be unable to do anything.

“I understand that part, but how do you plan to destroy the magic barrier?”

“I have a secret plan!” (Peter)

“Secret plan?”

“Yes, a secret plan.” (Peter)

Peter was brimming with confidence, but…

＊　　　＊　　　＊

“Even the daring and resolute Duke Nürnberg— In the end he only keeps defending—”

“Your remarks are as rude as always, aren't they?” (Nürnberg)

“I am just stating the truth.”

This is the deepest part of the underground fortress which had been built by making use of the underground ruins. I have set a rule that no one besides me can enter this central area of the fortress.
Having said that, this room isn't particularly important.
A large quantity of books and documents has been placed inside. The demon sits on a chair and simply relaxes while reading a report about the excavated items that had been used so far.

“The improved absorption magic circle is a huge success.”

The breath-generating devices that had been installed in the fortress, the powerful 『Magic Barrier』 and the maintenance of the device jamming 『Communication』 and 『Movement』, all of those function by using the demon's mana.
Magic circles that absorb mana have been drawn on the ceiling and walls of this room. It's a construction to put the mana of this demon to use for keeping up all the devices.
Thanks to this demon, the imperial army can't do a single thing.
I can't stomach his overwhelming power, but as long as this guy's here, we should be able to hold the fortress for a decade.
And the changes taking place in 10 years are so many that you can call this day ancient history 10 years later.
Even the population of my Nürnberg Dukedom shouldn't yield that easily to the Empire. There's also the possibility that Peter will fail in domestic or foreign affairs so that it'll become my turn.
Even the Helmut Kingdom, which is firm like a rock right now, might fall into disorder.
Earl Baumeister achieved military deeds that outshadow the others in this time's civil war.
It's possible that just his return to the Kingdom will trigger chaos in that country.
It's conceivable that Helmut the 37th, who plays the unconcerned wise ruler, and his inconspicuous crown prince will scheme to remove Earl Baumeister out of jealousy.
However, we are talking about that Earl Baumeister here. He won't allow the royal family to purge him just like that.
Even if he himself wouldn't wish for an expansion of the disorder, it's possible that his surroundings would oppose the Kingdom in order to protect him.
If the situation develops this far, even Earl Baumeister will likely resolve himself to rise in rebellion.
Even that man shouldn't be eager to die young.
Yes, if I preserve, another chance for me will come around sooner or later.

“You are absorbed in various crafty political deliberations.”

“Well, yeah. I'm a weak person, so I won't survive unless I take various things into consideration. Why are you helping me?” (Nürnberg)

“There are plenty of places and things here which I have not investigated yet. Ten years will pass in the blink of an eye if I get started on that.”

It's not for my sake, but solely to still his thirst for knowledge as archeologist.
Maybe he's trying to form a connection with the continental expansion faction by passing on information to the demon country. At present it doesn't look as if he has made contact with the outside, but I must not be careless with this demon.

“At this rate it will be possible to hole up here for many years as long as nothing happens, but the enemy is shrewd as well. Are they going to come up with something? Is what this me foolishly wonders.”

“They are probably planning to do so.”

Right now we can buy time with the strong 『Magic Barrier』.
During that time I have to urgently create a system so that the morale of the retainers, soldiers and their families, who have secluded themselves together with me, doesn't fall during that long period of time.

“For that reason I didn't allow anyone but chosen people to participate in the fortress defense. Right now the highest priority lies with the construction of an underground shopping area for them.” (Nürnberg)

“You are going to establish a common everyday's life albeit secluding yourself for a long time. However, how nice of you to be stuck in such reckless castle defense.”

It's none of your business, demon! Just what do you think how much I had to endure to create this army corps!?
This demon is irritating, but at the same time useful.
I will use him to the utmost limit. For now I will have him prepare for the castle defense.

＊　　　＊　　　＊

“I see, you are going to destroy the 『Magic Barrier』 by using a powerful magic cannon.”

“Yes. For that reason High Earl Mizuho's and Kanesadsan's powers are indispensable, Peter said.”

“I'm a mere katana smith though. That prince is skilled at asking for things of you, Earl Baumeister, while acting like a spoilt child.” (Kanesada)

The plan Peter showed me is plain and simple.
The strategy was: “If the 『Magic Barrier』 is powerful, won't all be fine if we destroy it with a cannon that has an even stronger power?”
The hint was apparently the huge sniper rifle that Wilma used during the fight against Rainbow Assault.
It's also good that we don't have to fuss over the sniping precision this time. In short, the biggest obstacle is building a cannon barrel that won't break at the time of shooting a shell loaded with a huge amount of mana.
This kind of metalworking technique might have been known to dwarves if this was another fantasy world, but since they don't exist in this world, it's the best option to leave it to the Mizuho people who have the technological knowledge.

“Of course, since the Mizuho engineers won't be enough, I will also send engineers from the Empire as assistance. Just use them as you see fit while thinking of them as your subordinates.”

While acknowledging the technological power of the Mizuho people, Peter sent craftsmen and engineers as helpers in order to to allow the Empire to catch up as fast as possible. They are going to try absorbing as much of the Mizuho people's techniques as possible in the process of helping.

“High Earl Mizuho, what about the blueprint?”

“It's this one.”

High Earl Mizuho shows a blueprint to Peter.
A fairly huge magic cannon was drawn in details on that blueprint.

“Are you really going to build this?”

“If it's not at least that big, it won't be able to penetrate the 『Magic Barrier』 according to our calculations.”

“Won't the barrel explode in worst case if you fire a cannon ball with such a huge cannon?”

“It will. In the past there had been casualties during the test runs of a prototype. Unable to bear the impact at the time of firing, the barrel exploded, causing deaths and injuries among the craftsmen.”

“Is it going to be alright, Wendelin?”

“I came up with a countermeasure, but I won't know if it works unless I actually test it out.” (Wendelin)

I don't want to participate in a siege in Nürnberg Dukedom for many years.
We will blow away the magic barrier with an improved, big magic cannon and capture the underground fortress with the whole army in one go.

“Uwaah, how reliable you are, Wendelin. If I was a woman, I would take you as husband.” (Peter)

“And then you would bother him like me by approaching him forcefully?” (Therese)

Peter, a woman…that's nothing I want to imagine. If Doushi was a woman, just the imagination would already be in a different dimension.

“Anyway, I will join in on the improvement of the magic cannon.” (Wendelin)

Since I also got Peter's permission, I cooperated with High Earl Mizuho and we began with the production of the cannon.

◆◇◆◇◆

“A cannon said to be impossible to build. The metals for the sake of strengthening the lacking barrel, the technique to cut it precisely in a straight line, the production of a special huge shell and the development of peripheral devices and a connection with the magic gems that will provide the mana to let the shell fly. Many difficulties lie ahead, but the men will overcome them.”

◆◇◆◇◆

“Why such unnatural way of talking?”

Since I joined the production of the 『Big Magic Gun』 without delay, I tried to imitate the style of a certain ○roject X narration I saw during my childhood in my previous life, but Erw, who doesn't know the real thing, didn't like it.
Though I believe that this difficulty is worth being broadcast.

“First, the initial problem is the processing of the metals which will become the barrel's basic materials.”

Kanesadsan swiftly mentions the first issue.

“It has to be a durable metal, right?” (Erwin)

“Erwin-dono, if the metal is only durable, it's as if you are saying that it should be all made out of orichalcum.”

“That will be difficult, won't it?”

According to the blueprint, just the barrel has a diameter of close to one meter.
With the barrel having a length of 20 meters, it would be impossible to make all of it out of orichalcum.
Even if we gather all the orichalcum on the continent, the amount will still be insufficient, so it's probably logical that it won't work.

“So, what are we going to do?”

“We will make an alloy.”

“Alloy?”

“We will create a high-quality steel and add small amounts of mithril and orichalcum to it.”

High Earl Mizuho explains the way of making an alloy with a high durability to Erw.

“Accordingly we are going to rely on your knowledge and experience, Kanesadsan.” (Erwin)

“Well, it's an honour to receive such a high evaluation by you, Erwin-dono, but it's impossible for me.” (Kanesada)

Kanesadsan states that he won't be of much help in making that alloy.

“There are several problems. First, in order to homogenize the strength of the alloy, it's necessary for the steel to have an uniform distribution. That's indispensable so that there won't be an offset in the material at the time of adding mithril and orichalcum.”

It's not so bad when it's just one katana part, but this will be the barrel of a huge cannon.
It has to be made while melting and casting these metals equally. With the normal way of doing things it won't be possible to make such a huge casting.

“Eh? What should we do then?”

“If it's Earl Baumeister, he is probably capable of making it.”

“It might be possible.”

Erw looks at me.
If it's me, who can create a highly-pure ingots out of gathered metal with magic, I might be able to make the fine adjustments of the alloy's composition.

“Since it will be my first attempt, I have to practise…” (Wendelin)

After I take out my wand, I start from transforming large quantities of iron into steel.
If I remember correctly, small quantities of all kinds of metals are mixed into steel that has a solid tenacity. I think those were tungsten, chromium or nickel.
I was able to harvest those types of metals together with the iron, although it was small amounts when I was looking for them with 『Detection』.
Since they are only part of an alloy, I shouldn't need that much.
Also, carbon. I should add this as well, but the Japanese steel makers in my previous life didn't officially announce the distribution ratio of special steel. Since it's a company secret, that's only natural, but thanks to that I don't know what mixing ratio to use.
Moreover, I have to add mithril and orichalcum in addition to the other metals.
Given that these two metals don't exist on earth, I'm honestly struggling what kind of mixture ratio to apply here.

“For the time being, there are ancient documents, but…”

In a part of the documents shown to me by High Earl Mizuho, the ancestors of the Mizuho people wrote the mixture ratio of a special alloy that's sturdier than the steel produced by them in the era of the Ancient Magic Civilization.

“It's a lost technique. Even if you make the alloy according to that mixture instruction, it won't succeed for some reason.”

That probably makes sense.
It's likely possible if I use a special furnace, but it's unlikely for furnaces that use mana as fuel and the furnaces installed in houses to succeed in combining impurities with iron.
The condition that you have to mix the elements uniformly obstructs the success as well.
Even if I accomplished it, its durability will likely suffer and the usability will be gone if even a little bit of impurity enters the alloy.

“Are you going to be alright, Earl Baumeister?”

“It will be trial and error.” (Wendelin)

Anyway, I will remove the impurities from the iron with magic as much as possible. I will decide its mixture ratio with the other metals after measuring its weight.

“Or rather, we really don't know the criterion for success, do we?” (Peter)

Peter, who brought the precious mithril and orichalcum owned by the Empire, asked High Earl Mizuho a very reasonable question.

“According to the documents, the alloy will emit a pale light for an instant, if you add steel, mithril and orichalcum at the set ratio and mix them equally. The alloy made in this condition is called 『Extreme Limit Steel』. It's written that it will display the highest performance as multipurpose material.”

“I'm relieved if there's a criterion for success. I wondered whether you would have me hand out precious mithril and orichalcum each time you fail.”

“No, I won't use any more materials than these.”

Where creating a furnace is concerned, there will be blunders as well, but even if I fail the further refinement with magic, I just have to start over again.
Besides, all I need is an amount in proportion to the weight of orichalcum, mithril and steel.
The bigger problem here is that the ancient document doesn't mention just how much elements with low visibility such as tungsten, carbon, chromium and nickel have been added to the steel in the era of the Ancient Magic Civilization.

“(I guess I have to find all of that out through trial and error, don't I?)”

It will probably be necessary to run through thousands, no ten thousands of trials of repeatedly changing the mixture ratio minutely.

“Won't such complicated alloy combination trials take all day? That's impossible for me.”

Katharina, who came to check the situation, gave up with just hearing the story from me.
She had apparently gathered iron and exchanged it into money, but as the quality wasn't overly high, she couldn't sell it for much.
The gathering of iron and other metals by magicians makes the individual differences in quality apparent.
If there are people, who can't buy anything but iron with a lot impurities at a lower price, there are also those who are supported by public finances like master.
Either way, the point is to remove impurities with an image that suits you.
I use an image of logically lining up the atoms of iron as much as possible while ejecting other atoms to the outside. It's the same with other metals as well. That's also the reason why the quality of an metal ingot created by me is high.
Now that it has come to this, the studying during my student days, which I considered to be only for the sake of passing the exams in my previous life, proved to be useful.

“Wendelin-san, you are strong at such plain spells, aren't you?” (Katharina)

“Aaaaahaha! I mean, I didn't train in the Savage Lands by myself for nothing.” (Wendelin)

“It might have served as training, but it's nothing overly enviable.” (Katharina)

The reason for Katharina to think so is easy.
It's probably because she recalls the time when she trained as a loner just like me.

“Burkhart-san, are you going to work as teacher today as well?” (Wendelin)

“Yes.” (Burkhart)

There's no other magician as skilled in teaching as him.
Because of that he's taking care of a great number of rookie magicians upon Peter's request.
Given that a fair number of experienced magicians of the Empire died in the civil war, young magicians ranging in age from 7 to 13 years were gathered and are now receiving training from Burkhart-san while working as aides in the imperial army.

『It would be wonderful if there was a second Earl Baumeister among them!』 (Armstrong)

『Doushi, a too harsh training is not allowed!』 (Burkhart)

『Why? At their age Earl Baumeister has…』 (Armstrong)

『Earl-sama is a very rare case.』 (Burkhart)

Most recently the bored-looking Doushi joined their training as well. Though it seems he was given a warning by Burkhart-san when he tried to train them in the same way as he did with me.

“Seeing as the mixture ratio of the rare metals moves in the range of one hundredths of percents, I will have to comb through a huge number of combination patterns.”

“The only one capable of that is you, Wendelin-san.” (Katharina)

The rough mixture and molding has been already finished.
The raw materials of the cannon barrel with its diameter of one meter and its length of 20 meters have been placed on a special stone stand prepared by High Earl Mizuho.

“Besides, I will need to slowly change the mixture ratio while making sure to not forget to evenly distribute the metals in order to avoid adding hollows to it…”

It's the repetition of doing the same work over and over again, or rather – going by appearance – I'm simply casting continuously magic on the raw materials of the barrel while holding a cane in both my hands. With the work going on for the whole day, I ended up unable to change the mixture ratio once I ran out of mana. Towards the evening I used up the majority of my mana and thus simply slept afterwards.

“You have to keep at it patiently.” (Ina)

“That's the kind of work most unsuited for me.” (Luise)

Ina and Luise, who brought lunch as errand from Elise at noon of the next day, speak up to me who sits in front of the barrel.

“After all there's an infinite amount of combinations. It should have a bit leeway in its tolerance levels. Otherwise even the Ancient Magic Civilization shouldn't have been able to produce it.” (Wendelin)

Once I enter the permissible range, the gun barrel will emit a pale light for an instant. Aiming for that, I simply continue adjusting the composition with magic patiently.

“Maybe there's also an effect from you having fought Alfred before?”

“I'm sure there is.”

It's a plain work on the first glance, but keeping up this magic also serves as measure to fix my 『crudeness of control』 mentioned by master before. You can call it a homework for me who went through a tough battle while possessing a lot more mana than master.

“But Burkhart-san told us, didn't he? No matter how much of a genius Alfred might have been, he was never that great when he was around your age, Wend.” (Ina)

“In the past Burkhart-san gave Alfred the same advice.”

He was noticed because of his big mana pool, but in the end a young magician has to become skilled at magic control.
Since master was still a young man back then, he apparently received the same advice from Burkhart-san.

“Either way, as long as I don't manage to finish this, we won't be able to invade the underground fortress. My only option is to tackle this problem.” (Wendelin)

Right now it's only about perfecting the cannon barrel's raw materials anyway.

“Wend-sama, bento.” (Wilma)

“Thanks. I heard that you are in charge of firing and aiming, Wilma, but is that true?” (Wendelin)

“I'm valued for my actual experience in the battle against Rainbow Assault.” (Wilma)

“I see. Do your best.” (Wendelin)

“Yeah, I will.” (Wilma)

Because the handling of the magic cannon is the same as the handling of a normal cannon, there's no necessity for precise aiming, but we still have to arrange for a shooter.
Wilma had been assigned to that task because of her experience with the large sniper rifle prototype.

“The production of the cannon mount and the shooting device has begun as well.”

There's a lot of peripheral equipment necessary to operate this huge magic cannon.
A sturdy cannon mount to support it, an aiming device, a firing device and magic gems to store huge amounts of mana in advance. Since a single magic gem won't be enough, they seem to connect several of them together. Given that it's a technology that failed when they tried to apply it for the huge magic airship in the Helmut Kingdom, it was obvious that this would prove difficult as well.
In addition a highly efficient cooling device is indispensable as well.

“The polishing of the cannon balls made by you, Wend-sama, has started as well.” (Wilma)

These have been made out of tungsten and other metals, but as there still seems to exist a difference in size and unevenness if my molding is used, several craftsmen are busy polishing them.
Many people are involved with the production of such a huge cannon. Therefore failure is no option.

“You have also been put to work, right Luise?” (Wendelin)

“I'm in charge of providing additional mana. So you have to tell me that I should do my best, too.” (Luise)

“Luise, do your best.” (Wendelin)

“I will.” (Luise)

Luise unleashed a technique of charging her fist with mana exceeding her own several fold in the battle against the Rock Gigant Golem in the Herthania Valley.
Making use of that special skill, she accepted the duty of assisting by providing mana through the magic gems.

“It has taken a weird shape in the training, but I think it won't actually be too much trouble.” (Luise)

Making use of the magic gems filled with mana by other magicians, Luise will amass mana in her fist to the limit and then drive it into the cannon through a mysterious cord. Matching with the mana from the linked magic gems, a huge amount of mana will be forced to explode in one go to shoot a special cannon ball with a big calibre.
Of course normal magic cannon materials would rupture.
It all depends on the workmanship of the 『Extreme Limit Steel』 that I will create.

“Wend-sama, keep at it.” (Wilma)

“Go for it, okay?” (Luise)

“Aye, I will.” (Wendelin)

For one week after that I improved the adjustment of the mixture ratio little by little, but somehow the barrel doesn't want to shine.
Gradually the cannon mount and the the other peripheral devices took shape nearby.

“Dear, are you alright?” (Elise)

“For thee to have reproduce OOParts lost in ancient times; thou sure have it difficult, Wendelin.” (Therese)

Today Elise and Therese showed up while bringing my bento.

“Elise, is the first-aid station holding up well?” (Wendelin)

“Yes. Since there's almost no combat recently, it's not that hectic.” (Elise)

Since the fortress is protected by a sturdy 『Magic Barrier』, the imperial army is simply encircling the area without starting any battles. Occasionally a supporter or spy of Duke Nürnberg tries to pass through but their capture seems to only create a small stir.

“If it's only that level, even the empire's magicians are able to handle it somehow. Besides…” (Therese)

“Besides, what?” (Wendelin)

“The young soldiers deliberately suffer scratches and cuts for the sake of getting healed by Elise-dono.” (Therese)

It appears that the number of soldiers lining-up at the first-aid station after deliberately suffering wounds in their desire to be healed by Saint-sama has increased.

“Again?” (Wendelin)

Now that she mentions it, wasn't it the same during the dispute…?

“I have been told that I don't have to come to the first-aid station except at times when there are fairly heavily wounded people.” (Elise)

“After all the number of patients lessens if thee are not there, ELise-dono.” (Therese)

Deliberately getting injured; damn, are there no guys who receive healing from male priests? Realizing my thoughts, Therese seems unable to hold back her laughter.

“There are also many of the locals going there as part of the imperial army's pacification efforts, but…”

The imperial army set up free medical treatment and physical examination for the local residents in order to smoothen the military rule of the Nürnberg Dukedom. Given that there are many women, children and old people in the territory, Elise apparently wanted to participate.

“Elise-dono, I understand thy sentiments, but the empire's church has its own pride. It's better to hold back except for the times as helper in the worst case.” (Therese)

“Because the headquarters of the Protestant Church is located in the imperial capital, the time they obeyed Duke Nürnberg wasn't long. For them it's important to show Peter their merit. Since Mister Baron, who became one of his influential retainers, has a deep relation to the Catholic church, they feel an impending danger that Peter might ignore them, who ought to be the state religion, under his rule.” Therese explained the circumstances.

“Elise-dono, thou are a catholic, too. It's best for thee to not show your face much unless it's really a case the priests can't cope with.” (Therese)

“I guess you are right.” (Elise)

“Well, they are no idiots either. They shouldn't let a patient die due to holding onto some foolish pride. If they know that no one except for thee, Elise-dono, can heal the patient, they will likely request thy help.” (Therese)

If they allow patients to die for no reason, the reputation of the Protestants will fall instead. Therese said they they should ask for help if it looks impossible to them.

“Though Doushi might make a move before that. After all he was very angry over thy matter, Elise-dono.” (Therese)

『To harbour such evil emotions towards my niece! If they injure themselves so much, I will heal them!』 (Armstrong)

“The young soldiers, who wanted to be healed by Elise, threw Doush into a rage due to them rushing the healing station. The church might go to Doushi first if help becomes necessary”, Therese explained next.

“Therefore we have unexpectedly much free time. There won't be any change in the battle progress unless thou finish the materials of the huge magic cannon, Wendelin.” (Therese)

“You know it simply takes time since I have no other option but to test the material combination one after the other. In a way it also depends a bit on luck.” (Wendelin)

“It's a job requiring patience. Let me, who has little to do, feed thee. Here, aaahn.” (Therese)

“At the very least I should take a break for eating. Let us three eat together.” (Wendelin)

“Dear, everything has been prepared.” (Elise)
