Kemo Steele has hardly slept much these days, and he finds that coming to the border town is the most correct choice he has ever made in his life.

It took two days and one night to turn over the "primary chemistry" all over again, slept for two or three hours, and it was mentally shaken.Now he has returned to the first page and studied this ancient book carefully.

Matter is made up of very small particles!The change of matter is the decomposition and recombination of particles!During the reaction, the total amount of material remains unchanged!

God, what kind of person is the author of this book, can describe the world that people can not see so clearly.On more than one occasion, he suspected that the contents of the book were fabricated and fabricated, but the alchemy tests were carried out according to the above examples, and the results were fully met!Moreover, some common examples in reality can also prove that the book is correct.

For example, the oxygen described in the first chapter.

This gas is the main component of air, and people are not breathing air, but oxygen.Flame combustion requires oxygen because combustion is essentially an oxidizing reaction.The more oxygen, the more intense the combustion.

These words reminded him of the glass kiln of the city of Chishui, which required two people to keep shaking the airbag to raise the temperature in the furnace to the melting point of the sand.Since it is a substance, it can obviously also be obtained through alchemy... No, pure oxygen is extracted through chemical reactions.If you can directly go to the furnace to pass oxygen, can you save the blow molding equipment?

And the most amazing thing is that the book says that water is actually composed of two hydrogen particles and one oxygen particles, which is probably why all living beings drink water.But hydrogen seems to be a kind of gas, the two gases together into a liquid, this is how to do?

Kemo found himself to have a lot of questions to ponder.But there is no doubt that he has walked in front of all the alchemists, and while they were still groping for formulas in the chaos and fog, a straight and flat road appeared before their eyes.

However, the work has to be done.He closed the book.At this time, the sky has become white, and it is time to work again.

Kemo blew out the candle, approached the bedroom to look at his sleeping wife and daughter, and quietly went out the door.

His Highness assigned to his house, located west of the castle, was much larger than his own home in the city of Akashui, and the walls were made of masonry, which was evidently much more comfortable than the easy-to-mold wood, and had plenty of furniture and kitchen utensils.Although he did not say it, he was more satisfied.The disciples lived in another district two streets away from him, and the house was small and round, and it was not a separate house, but it was a bit like the arrangement of the hotel, and a bedroom could be used for four people.

Walking to the chemistry laboratory by the river, the disciples were already busy.They were carefully selected by Kemo, who had been learning to clean materials in the alchemy workshop almost as a child, and were now between the ages of twenty and thirty.Seeing the clean lab and the shiny glass container, Kemo nodded with satisfaction.

“Good morning, Chief Master,” the disciples bowed their heads together.

“Start it.”He took a pair of gloves out of the cupboard, which was extremely thin and flexible, presumably stitched with the intestines of animals.Previously, there was no such regulation in the alchemy workshop, but His Royal Highness repeatedly stressed the dangers of chemical experiments, and in the operating regulations, all those involved in the reaction of corrosive raw materials must wear gloves and open all windows at the same time.

Unlike the workshop, the content of their work is very clear now, that is, to produce acid for His Highness.The method of bistile acid has been operated many times, so Kemo only needs to tour the fingertips and does not have to go down in person.

These two acids are recorded in detail in the "primary chemistry", one is called sulfuric acid, and the other is called nitric acid.He used to use manufacturing to name, such as the former called green hydroxic acid, the latter called nitric acid.Different names, the production method is basically the same, through the dried distillate green alum and nitrite to get acid vapor, and then through condensation to get acid.Green alum is usually accompanied by sulfur ore, and nitrite has a special nitrate production in large cities, which is a common raw material.

However, His Highness stressed that the two acid concentrations he wanted must be high, and also deliberately explained the purification method.

For example, after the sulfuric acid is collected, the water can be evaporated by heating, and finally the concentration of up to xiutious sulfuric acid is obtained.However, nitric acid is a lot of trouble, listen to the Prince's Highness said that this acid itself is not stable, easy to volatilize, the concentration is high to a certain extent, and even see the light will decompose.Therefore, the dilute nitric acid that is dried must be mixed with concentrated sulfuric acid and heated, so that the concentrated sulfuric acid absorbs water, evaporates the nitric acid and stores it in a brown glass bottle.To this end, His Highness also specially prepared a thermometer.

At the first time he saw it, he thought it was a clever thing, a hollow glass tube filled with mercury, and both were sealed, not to worry about the mercury leaking out.The above is painted with several coils of paint, and the mercury will gradually rise when heated, and the final position of the residence represents the current temperature.

Today, the laboratory has produced three bottles of concentrated sulfuric acid and a bottle of concentrated nitric acid.At this concentration, he found that sulfuric acid does not flow as easily as water, but is more like a bit of viscous oil.Nitric acid in high concentration is no longer colorless transparent, but become pale yellow, as long as the glass cap is opened, it will emit a burst of white smoke.

“Master, do we have to make these two kinds of acid every day?”A student named Amon asked.

“Until His Highness gives a new mission.”Camorton said, "What's the matter, worry that there is no time to explore the alchemy formula?"

Amon nodded his head.

Kemo smiled at the chin's garb, "Forget to tell you that the title of the alchemist will not be needed, so you don't have to rely on the formula to become an alchemist."

“No,” Amon stam stam, “no need?”Other disciples also slowed down the work at hand, listening to the teacher's next words.

"Yes, the alchemy formula does not need to be groped, but to memorize and derivate," Camo clapped his hands, simply gathered everyone around, "Your Highness gave me a copy of the first chemistry - this is why I brought you here, if you study thoroughly, most of the formulas in the world can be speculated according to the contents of the book."

“Presuming it?”The students shouted a little.

"That's right.When I read it in detail, I will teach you a lesson.”He said, “As for the promotion, your Highness has also mentioned to me.In the future, you will have to pass the test he has personally arranged to get the title of chemist.Believe me, it won’t be long before this honorary title takes precedence over the alchemist.And the knowledge which you possess, even the King's alchemy, is beyond the reach of the earth."(Unfinished).
