Release that Witch

"The church is like a sudden pop."

Until returning to the office, Roland still echoed this sentence.

He closed his eyes and searched the memory of the four princes carefully, still could not find more relevant content. His understanding of the church is similar to that of ordinary nobility. In the palace, the four princes did not spend much time learning knowledge, and occultism was almost blank. But if Tilly is telling the truth, then the propaganda strategy of the church is too strange.

Take the original religious legends of the world as an analogy. The gods originated in the world at the beginning of the pediatrics. The world is created by the gods and is the routine that everyone chooses. For example, creation on the 7th, karma reincarnation, etc.... A set of legends that fully describe the power of God is the standard for every religion.

Compared with the church in this world, it looks quite...innocent.

However, Roland did not have more clues to continue the research. He shook his head and decided to leave these thoughts behind.

Perhaps after waiting to explore the ancient remains of the fascinating forest, everything will have an answer.

He walked to the window and looked at the huge coating on the ground in the garden - in the snow of the white, its green appearance was particularly eye-catching.

Now that Soroya is bonding more airbags, the new hot air balloon will be even bigger and more people can be carried. This is because if you can't find a way to save the trapped woman when exploring the ruins, simply let Anna chop the whole "ice" and bring her back to Bianbu Town along with a part of the transparent spar.

The departure time is scheduled to be two days later.

The staff has made arrangements for the sleepy island witches with Tilly, Sylvie, Sawyer, Ashes and Andrea. The Witch Alliance will send Anna, Wendy, Nightingale, Nana, Lightning, and McMug. This lineup is unprecedentedly powerful, with attack, defense and battlefield perception reaching the highest level. As long as the stone of the gods is not used, it is difficult for the devil to have a chance to approach them.

"His Royal Highness, the chief alchemist, Camo Spoel, wants to see you," said the guard outside the door.

"Let him come in."

Kemo did not come alone this time. He also took his own colleague Chamez. "His Royal Highness, the large-scale nitric acid method you requested, has already got a clue."

“Really?” Roland gave a slight glimpse, and then a burst of joy came to mind. This is probably the best news I have heard in recent days. He stood up excitedly and poured a cup of tea for the two chemists. "Quickly, how was it made?"

"This is the credit of Chames," he said with a smile on his beard. "Let him come and explain it to you."

"Respected Your Highness," the young Chames looked a bit cautious. He said after his salute, "Your alchemy workshop... No, the chemical laboratory produces nitric acid, which is obtained by dry distillation of nitrate. Then, it was purified by concentrated sulfuric acid. I tried to put the two together and directly heated the saltpeter into concentrated sulfuric acid. The result was a nitric acid solution, and the purity was very high. It can even be observed in the "Elementary Chemistry". The phenomenon of smoking."

“Common heat? But the two are not the same thing,” Roland said strangely. “The temperature of the dry distillation is much higher than that of the co-heating, and the gas that is retorted should be nitrogen oxides. When it is introduced into the water, it forms dilute nitric acid. Concentrated sulfuric acid. Purification is simply the use of its high boiling point and strong water absorption principle to reduce the water content in nitric acid, and does not involve chemical reactions."

"I don't quite understand why, but Mr. Stern did a few experiments and thought that my discovery was a coincidence."

“Coincident?” Roland looked to the chief alchemist.

“It’s true,” Kemo affirmed. “The two are not the same, but they have the same effect. I deduced it according to the chemical formula and guessed that this should be a reaction of some of the components of the saltpeter with sulfuric acid. Nitric acid is evaporated and evaporated in the heat. According to the formula, it looks like something... well, nitrate."

Roland’s mind suddenly remembered that it was mentioned in the chemical textbook that before the artificial ammonia was invented, sodium nitrate or potassium nitrate was reacted with concentrated sulfuric acid to produce nitric acid, which is the oldest industrial method. Because the main component of saltpeter is two kinds of nitrates, it is convenient and easy to obtain, and the extraction is also relatively easy. As long as the temperature is controlled, the source of nitrogen can continuously collect the evaporated nitric acid.

Of course, because this method consumes a large amount of sulfuric acid and is extremely susceptible to corrosion, it was quickly eliminated by more advanced technology.

However, these two points are not too big for Roland. The chemical fertilizer and pesticide industry has not been established in the territory. The sulfuric acid produced is only for the purification of nitric acid. As for the strong corrosiveness of nitric acid vapor, it can be given to Solo's coating is solved.

"Good job," Roland patted Chalmers' shoulders with delight. "This method can be tried out by you."

"You don't know, he has shown extraordinary luck at the Chishui City Alchemy Workshop," Camo Stoucher raised his eyebrows. "Before learning chemistry, alchemy itself is a kind of exploration that requires luck." And this kid can find out the double acid method in the early 20s, becoming the youngest alchemist in the workshop, and envying a group of 30-40-year-old apprentices with envy and envy. They must know that they will live their lives. It is probably just an apprentice."

"In any case, this is good news for the town," Roland praised. "You try to make a batch of equipment to see, I will let the witch cooperate with you. If possible, expand the scale of production."

"As you wish."

"Right, I have another task to hand over to you," and he put away the joy of joy, saying in a solemn tone, "There is a reliable source of nitric acid, and then I need you to try it as dangerous. Item - nitroglycerin."

“How dangerous is it?” asked Kemer.

“The raw material used is very simple, that is, concentrated nitric acid reacts with glycerin and is catalyzed by concentrated sulfuric acid, but the temperature must be strictly controlled during the reaction and kept ventilated. Since a large amount of heat is generated during nitrification, you can place the container Experiment in ice water. Remember, cold, heat, vibration, impact, and friction can cause it to explode.” Roland doesn’t know if these amateur knowledge is unreliable, but the ingredients are undoubtedly correct, even if there is danger. Also have to try. "It's good to use a small amount of acid during the test, so even if an accident occurs, Miss Nanava can rescue you."

"This..." Chames opened his mouth and had not had time to answer. Kemer had promised it. "I understand, its power is compared with snow powder?"

"The weather is far away."

“It seems to be an interesting experiment.” The chief alchemist smiled.

Nine of the ten chemists are potential explosion art lovers, and that’s true. Roland thought.

Nitroglycerin is extremely unstable, and Nobel's safety is to add diatomaceous earth to passivate the ester. Although it improves safety, it reduces the explosive power. Roland naturally does not use this classical method. He intends to add nitrocellulose or nitrated starch to nitroglycerin, both of which can stabilize and further enhance the explosion. The former is an excellent smoke-free propellant, while the latter is a powerful force. As can be seen from their names, a large amount of nitric acid is the key to the evolution from black powder to chemical gunpowder.

And he now has this key.
