Wizard: I Brought the Wrong System Chapter 360

After finishing all this, Yarrow tidied up the ground a little, and then took out the skull mask.

The addition to this skull mask is not the official spell 'walking underwater', nor is it the constant mid-level trick 'breathing underwater', but as long as water is added to the interlayer, Yarrow can ignore the surrounding air environment.

The reason for all this lies in the magic patterns that can generate tiny electric currents.

That's right, it's electrolysis.

The skull mask is equivalent to a beautifully made electrolytic cell, relying on the magic power of the world, using magic stones as energy to generate a subtle current, and continuously electrolyzing the water in the interlayer into oxygen and hydrogen.

This is the knowledge learned from the previous life, and now he is going to use the mask to continue to use this knowledge.

- Make the caustic soda required for the saponification reaction.

Caustic soda, also known as sodium hydroxide, is a strong base that does not exist in nature.

There are many ways to prepare caustic soda, but Yarrow has limited materials, so he plans to obtain it by electrolyzing saturated brine.

After saturated brine, sodium hydroxide, chlorine gas, and hydrogen gas can be obtained.

Among them, chlorine gas and hydrogen gas flew into the air, and only sodium hydroxide was reserved in the liquid.

Air pollution?

what is that?

Wizards don't like this!

After enough sodium hydroxide was produced, Yarrow took out some saltpeter. Melting the saltpeter into the water would absorb heat and keep cooling down, and the water inside would gradually freeze.

Caustic soda will condense at a few degrees, but salt will condense at minus ten degrees, and caustic soda can be extracted by crystallization.

Of course, the caustic soda extracted in this way will inevitably contain impurities, but Yarrow does not have high requirements for concentration, which is almost enough.

Put the prepared caustic soda aside and let the water flow out.

Taking out the oil accumulated over several months, it is not much - in terms of conversion, it may not be as many as two barrels of vegetable oil in the previous life.

Perrin Castle was short of livestock, and the servants in the castle also had to eat oil. Yarrow himself was a big oil eater. He was able to accumulate so much oil, thanks to the help of White Deer in hunting.

Next, Yarrow prepares to use the knowledge of the previous high school - saponification reaction.

The saponification reaction is not difficult, and no other additives are required, but if you want to speed up the reaction, you can add some alcohol to reduce the consistency of the oil and make it easier for the caustic soda to penetrate the oil.

Yarrow didn't prepare alcohol and didn't think about those things.

Put the oil, heat it, wait for the freezing point animal fat to dissolve, and then put the caustic soda prepared earlier.

The next thing is to wait. In order to prevent the grease from re-condensing, and because this process also requires a temperature of 90-100, Yarrow added a pot of water in the middle, and the water temperature was used to maintain the reaction process.

Taking advantage of this spare time, Yarrow first took some food out of the space ring, and while eating, he observed the situation in Perrin Castle.

Fortunately, in just half a day, Perrin Castle did not change much.

Seeing that there was no sign of a trigger point for the 'bait', Yarrow skipped the telescope and turned back to continue making tools.

The saponification reaction does not use too much caustic soda, and Yarrow is useful for the remaining caustic soda.

Dissolve the caustic soda and continuously pass carbon dioxide into it to gradually turn it into soda ash.

With soda ash, making glass is simple.

The addition of soda ash can not only lower the temperature required to make glass, but also reduce the bubbles contained in the glass.

Of course, there are advantages and disadvantages. Glass containing impurities will reduce the mechanical strength and chemical stability, so limestone is generally added to ordinary glass.

Yarrow has no place to find limestone now, so he can only put less soda ash, and he can continue to make glass by increasing the temperature.

As long as you are willing to use the lava stone, even if you lack some materials, it is not difficult to make glass.

Large beakers, catheters, glass rods... With the passage of time, all kinds of utensils are constantly taking shape in Yarrow's hands.

When the sky was completely dark, Yarrow finally made these utensils.

At this point, the saponification reaction was finally done.

Illuminate with light, move the glider a little distance, and make sure no light is coming in the direction of the castle.

Saturated brine was added to the saponification reactor, and the solution showed that a layer of milky white viscous material appeared soon.

- This is soap.

The remaining ones are the by-products of the saponification reaction - glycerol.

Of course, glycerin also contains a lot of salt and water.

Continue to heat, the salt will not evaporate, so it will stay - collect the 'mysterious gas' and cool it to get the 'mysterious liquid a'.

The sulfuric acid is burned to collect the gas, and oxygen is added to the water to obtain the 'mysterious liquid b'.

Put saltpeter in the 'mysterious liquid b', heat it, collect the gas, and mix it with water to get the 'mysterious liquid c'.

Adjust the concentration, mix the three items...wait.

Boom...!

A muffled thunder rang out in the dark sky.

A white light lit up, and after a while, it gradually subsided.

The cool night wind rustled the surrounding leaves.

Yarrow raised his head and glanced at the sky, thinking in his heart: "Is it going to rain? It's getting really fast. UU reading www.uukanshu.com"

But he wasn't worried, anyway, with the 'glider' as the roof, the rain couldn't catch him.

Just need to deal with the surrounding gaps to prevent wind and rain from coming in and affect the rest at night.

Even after a hard day, little Heli still doesn't feel tired.

Not to mention that she came from a poor family, but that those things were personally explained by Lord Yarrow.

This kind of thing that can help adults, she just thinks that there are not enough, if it is not that Lord Yarrow is not allowed to light the lamp, and if the servants still need to rest, she will continue to do it without sleep.

How can you feel tired?

Speaking of Lord Yarrow, little Heli thought of Miss Bailu inexplicably.

"Why didn't Miss Bailu come back with the adults? Did she go home directly? Did she sing that song to Lord Yarrow?"

"Miss Bailu is so beautiful, she is a perfect match for adults!"

"Not like me... thin and small, with dry red hair."

The little girl's emotions came and went quickly. She only mourned and complained for a moment, and then cheered herself up again.

"Since I can't continue to help Lord Yarrow purify materials at night, then I'll be the generator that Lord said!"

"When the lord comes back next time, I will show the generator to the lord!"

Thinking of Lord Yarrow, the little girl's eyes became two crescents when she smiled, and she jumped when she walked.

After trotting to the familiar laboratory, Heli carefully picked up the ordinary-looking stone from the experimental bench, and then took out the personal notes from her bosom.

"What should the generator do?"

The little girl pursed her lips and checked it carefully.
