Mael Kael said as he sleeps in his bed. In his previous life, he is a trained killer of the police, trained to assassinate high profiled criminals and big syndicates. After destroying all syndicates, he then retired and will make a family with his girlfriend Jane. They are happily wed and on their honeymoon, they slept but then he realized that he can't move after several minutes. He was killed in his sleep by his own wife.

"Wake up darling"

A sweet kind voice permeated his ear and then Mael opened his eyes. He saw two people that was holding his little hands in a very kind way.

"Maybe it is mother and father", Mael said as he slept again.

He was a boy born from the family of Erza Kael and Lord Melvin Kael. They lived in the Manor of Golden Valley. They have land given by the king and a mansion, vast lands, an estate, and a town to rule. The World he lived in was the World of Lumia inhabited by variety of creatures such as vicious monsters, humans, demi-humans, and beast mans.

"Mama! Papa!", Mael shouted to them when he is one year old.

"My child can talk!", Melvin said to Erza.

"He is a genius!", Erza said to him.

Time passed by, he was now already a four-year-old boy by this world's time. He was taught by his mother Erza to read and write and well, he was a fast learner when he was still a trainee assassin. Well, of course, he learned to read and write in a terrifyingly fast degree. With all that concluded at the age of five, he was reading books about history, and random stuff like heroic stories of olds, monsters bibliography, kingdoms and races, and as well as the prophecy books. With all he learned, he is still running out of books to read.

Mael approached his mom that was still sewing his dress, he grabbed the tip of her skirt and then pouted.

"Mom, I'm running out of books to read. I'm gonna die of boredom with this", he said.

"What? Did you finished them all?", she said, while shocked.

"Okay, there were still books that you have to read. Let's go to the library", she said to him.

Mael and Erza walked to the library located beneath their house. It was a mini library that had a bookshelf. There's a secret mechanism to open the underground library. Erza illuminated the room using the lights of lanterns. The books were filed on the bookshelves and there were many books that he haven't read yet.

She grabbed the books one by one and she piled them on her son's hands.

"The herbalist book—Oh here! Survival book. This one's important! Basic magic, basic enchanting, and this one's advanced! Alchemist book, crafting!, Job-classes of different races and their specialties", she said then Mael walked like a drunk, trying to balance all the books piled on his arms.

After reading the kingdoms and races, as well as their job classes and specialties, he discovered everything about them.

There were three factions of Lumians, first were the Humans which had three kingdoms: Farmas the Barbarian empire of barbarians, Dwight the Royal Kingdom of royals, and Skuld—the Death kingdom of necromancers and witches. Second were the demi-humans: the kingdom of Elves Riverdell, Dwarf kingdom Dwarven, and Hobbit kingdom Clockwerk. Last were the Beast-man faction: The Lycans called Fang kingdom, the Vampires called Blood kingdom, and Druids called the Grizzly Kingdom.

Humans had three kingdoms and the Barbarians were the pinnacle of humanity's warriors. They were known to be taller than most humans and had a body build of bulging muscles. Their class were barbarians and they were specialized on all melee weapons. The Dwights were the ones who have many job classes that was collected from many lineages and families. But they were inferior when it comes to resilience compared to barbarians. The Skulds were the united forces of witches and necromancers. They were once divided. But after the king of necromancers and the queen of witches had an affair, they wed. Thus, united their forces and established a kingdom.

Next, were the demi humans: first were the Dwarves, they were the masters of crafts when it comes to blacksmithing weapons and armors. They were the most armed when it comes to their army. Second, were the elves. They have three clans specifically the high elves, whom were magicians; the night elves, which were rouges; and the wood elves, whom were rangers. Lastly, the hobbits, whom were called the mechanics due to their inventions of automatons that were powered by mana crystal. They had an army of automatons as well as battle suits that they were equipping when they go to battle.

The last faction were the Beast-men: the first one is the vampires, called blood warriors; and the other was of the ancient clans of beast-men that can transform to bat-like beast named as draculas. Next, were the Lycans. Transforming to werewolves and possessing the ability to summon wolves that would attack for them. Last were the Druids. They had druid shamans and warriors that can transform to werebears.

His mother even gave him books about job classes tutored in the academy of the Dwight Kingdom and their army. As you can see; in the job classes, the role of the combatant person that was used specifically for combat. For instance: the swordsman, ranger, knight, paladin, warrior, rogue, mage, priest, and fighter. He found out that he was capable of mastering it all, but the problem is the time to master it all. These kinds of job classes were only taught in the academy and the only things you can learn outside the academy were techniques. Yes. It was not a job class-dependent, but a matter of physical combat using only techniques of fighting: weapon techniques and unarmed techniques. It was not skill-based, because skills consumes mana and it is only a basic attack only using physical strength. Well, it was the time to ask for his father about his newfound info about techniques.

Gathering info was a success.

He approached his father and asked him kindly. As a previous assassin of criminals, it was important to know the info first before making the plan to attack. He learned it through his mistakes. He was making his greatest act and that is to make a dramatic scene for his plan to work. Because acting was one of his skills from his previous life.

"Dad, may I ask you something?", he inquired as he approached him.

"And what is it?", his father replied.

"About this book called 'combat techniques' that you wrote? Would you be pleased if your son was excited to learn your own fighting style?", he asked his father.

"No, son. It's still too early for you to learn it. I mean– you're still five years old! You still need to read lots of books as you can. Then when you're six– well, we can start with swords, then spear and so forth. But for the meantime, just read well. Okay?", he explained to him.

"If my age was the problem, well I can manage myself to dodge a bullet if forced to in my previous life. That's not it. The problem was my body", he said in his own self.

"Are you certain that your skills were really strong? Or you're just ashamed to show off of your skills to me?", he said as he handed the book to him, winked his left eye to him.

His father was moved and his pride is touched by an ignorant child. So he showed his techniques to him. His father lined up all the equipment that will be used like making a drill.

First, he demonstrated his swordsmanship. With all his focus, he slashed a combo of left and right diagonal slash then turned and slashed in a wide arch. That is called a sword technique, a technique on handling a sword on engaging combat.

Mael clapped his hands, but he had a thought in his mind that he will be a good sparring partner.

"Next", Mael said.

Next was the spear technique. The father swung his spear, turned and trusts it to the air. Then he pointed his spear making a clockwise motion, rapidly trusts by five times. Mael clapped then said "next".

Then his father showed him the bow and crossbow technique. He loaded three arrows to the bow and fired it all to the target points. Reloading it with three arrows in his hands, he fired it one after another, hitting all the marks. He then grabbed the crossbow reloaded it instantaneously rolled over and fired it to the mark. Then after, he dashed sideways as he released the bolt from the crossbow. He reloaded it again, then dashed backwards. He did a backflip, while releasing it in mid-air. All marks were hit. With no dull moment, he reloaded and fired it towards the two hundred meters distance target hitting near the middle of the bullseye.

Mael is impressed then said, "next".

The next one was dagger technique, his father slashed furiously all over the dummy. He made some distance then eventually throws it to its head. He grabbed it then he twisted the dagger sideways as he draws the dagger that ripped its face. He distanced himself, then he dashed and thrust the dagger on its belly. Then drawing the dagger from the belly in a gut ripping manner.

Mael said "bravo", while clapping his hands.

Next is two-handed techniques, his father lifted two-handed hammers and slammed it vertically to the dummy and all the dirt is flown over then slammed it to the other dummy sideways then it is flown through the distance. Only leaving barely recognizable dummy afterward.

"Next", said Mael.

Lastly, it was the unarmed techniques. He began striking the hands of the dummy with rotating hands. Suddenly, he was striking faster and defending at the same time. Then for the final act, he made a one-inch punch that made the dummy blown by the force.

"That's all. Aren't you impressed?", his father said as he is covered in sweat.

"Well, it caught my attention and I've stored it well on my memory. Might also learn it as fast as possible", he said while taking the book from his father and left afterwards.

His father let out a sigh as he watched all the mess on their training grounds. Disappointed for not even thanking him.

Meanwhile, Mael discovered the so-called techniques. He also discovered the leveling up of character stats by using a window card and your job class is leveling also. Your performance can be enhanced by the stat points that you will receive when leveling up after killing monsters. The character stats were based on strength, dexterity, vitality, and focus. All had the so-called " character sheet" and the "Job class sheet". His mother and father have all of those. Specifically, they have a Job class. But they didn't tell him which is which.

These needs further investigation. But he was still a five-year-old kid that has limited knowledge and understanding of this world. Besides, what was the reason he was reincarnated here? He wondered.
