The church seemed to pop up out of nowhere. Pen % fun % Pavilion www.biquge.info

Until he returned to the office, Roland still echoed this sentence in his heart.

He closed his eyes and searched through the memories of the fourth prince, but still couldn't find anything more relevant. He knew about the church like an ordinary nobleman - when he was in the palace, the fourth prince didn't pay much attention to learning knowledge, and the occult was almost blank. But if Tilly is true, then the church's propaganda strategy is too strange.

Take the religious legends of the original world as an example, the gods originated from the world at the beginning of the child, and the world was created by the gods, which is the routine that everyone chooses. For example, the seven-day creation, karmic rebirth, and so on...... A set of legends that fully describe the power of the gods is standard in every religion.

The churches of this world are quite ...... Tender.

However, Roland had no further clues, and he shook his head, deciding to put these thoughts behind him.

Perhaps when you are done exploring the ancient ruins of the Hidden Forest, everything will have an answer.

He walked over to the window and looked at the huge coating that lay out on the ground in the garden—its turquoise exterior stood out against the white snow.

Now that Soloya is bonding larger airbags, the new balloons will be larger and can carry more people. This is due to the fact that if she can't find a way to rescue the trapped woman while exploring the ruins, she simply asks Anna to chop up the entire "ice coffin" and bring her back to the border town along with some transparent crystals.

The departure was scheduled for two days later.

Arrangements have been made for the personnel to include Tilly, Sylvie, Savi, Ash, and Andrea on the side of the Sleeping Isle Witches. The League of Witches will send Anna, Wendy, Nightingale, Nanawa, Lightning, and Maisie. This time, the lineup is unprecedentedly strong, with attack, defense, and battlefield awareness all at the highest level, and as long as they don't use the Divine Punishment Stone, it is difficult for the Devil to get close to them.

"Your Highness, Master Kamo Stell, the Chief Alchemist, wants to see you," the guard said outside the door.

"Let him in. ”

Kaimo didn't come alone this time, he also brought his companion Chames, "Your Highness, you already have a clue about the large-scale production method of nitric acid you requested. ”

"Really?" Roland was slightly stunned, and then a wave of joy welled up in his heart. This was probably the best news he had heard in recent days, and he stood up excitedly and poured a cup of tea for the two chemists, "Tell me, how is it made?"

"That's a credit to Chames," he said with a smile on his beard, "and let him explain it to you." ”

"Your Highness," said young Chammes, who bowed a little stiffly, "your alchemy workshop...... No, the nitric acid produced in the chemical laboratory is made by dry distillation of saltpeter to obtain dilute nitric acid, and then purified with concentrated sulfuric acid. I tried to combine the two and heat the saltpeter directly in concentrated sulfuric acid, and the result was a nitric acid solution with a very high purity, and even the smoke phenomenon recorded in the "Elementary Chemistry" could be observed. ”

"But the two are not the same thing," Roland wondered, "and the temperature of the distillation is much higher than the cothermal, and the gas from the distillation should be nitrogen oxides, which are introduced into the water to form dilute nitric acid." The purification of concentrated sulfuric acid is just to use the principle of high boiling point and strong water absorption to reduce the water content in nitric acid, and does not involve chemical reactions. ”

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

"Coincidence?" Roland looked at the Chief Alchemist.

"Indeed," affirmed Kemo, "the two are not the same, but they have the same effect." I deduced the chemical formula and guessed that it was a component of saltpeter that reacted with sulfuric acid to form nitric acid, which evaporated in heating. According to the formula backwards, it looks like some kind of ...... Well, nitrates. ”

Roland suddenly remembered that it was indeed mentioned in chemistry textbooks that before the invention of artificial ammonia, people used sodium nitrate or potassium nitrate to react with concentrated sulfuric acid to produce nitric acid, which is also the oldest industrial method. Because the main components of saltpeter are two nitrates, it is convenient and easy to obtain, and it is relatively easy to extract, as long as the temperature is controlled, the evaporated nitric acid can be continuously collected.

Of course, due to the large amount of sulfuric acid consumed by this method and the fact that it was very easy to corrode the equipment, it was quickly eliminated by more advanced technology.

However, these two points are not too big a problem for Roland, there is no supporting fertilizer and pesticide industry in the territory, and the sulfuric acid produced is only for the purpose of purifying nitric acid, and the strong corrosiveness of nitric acid vapor can be solved by Soloya's coating.

"Good job," Roland patted Chamez on the shoulder happily, "This method can be tried out by you." ”

"You don't know, he has already shown extraordinary luck when he was in the Alchemy Workshop in Chishui City," Kemo Storier raised his eyebrows, "Before studying chemistry, alchemy itself was an exploration that required luck, and this kid was able to figure out the method of making double acids in his early twenties, becoming the youngest alchemist in the workshop, and his eyes were red with envy to a group of apprentices in their thirties and forties. You know, they will probably be just an apprentice for the rest of their lives. ”

"Anyway, it's good news for the town," Roland praised, "and you try to make a batch of equipment first, and I'll get the witch to work with you." If feasible, scale up production. ”

"As you wish. ”

"By the way, I have another task for you," he said, recalling his joy, and said in a solemn tone, "Now that I have a reliable source of nitric acid, I need you to try out a very dangerous substance—nitro*glycerin." ”

"How dangerous is it?" asked Kemo.

"The raw material used is simple, that is, concentrated nitric acid reacts with glycerin, supplemented by concentrated sulfuric acid catalysis, but the temperature must be strictly controlled and ventilation must be maintained during the reaction. Since nitrification generates a lot of heat, you can experiment with the container by placing it in ice water. Remember, hot and cold, vibration, impact, friction can all cause it to explode. Roland didn't know if this amateur knowledge was reliable, but there was no doubt that the ingredients were correct, and even if there was danger, it had to be tried. "Just use a small amount of acid in the test, so that even if something happens, Miss Nanawa can rescue you. ”

"This ......," Chammez opened his mouth, but before he could answer, Kemo had already agreed, "I see, how powerful does it compare to snow powder?"

"It's a long way off. ”

"It looks like it's going to be an interesting experiment. The chief alchemist laughed.

Nine out of ten chemists are potential blast art enthusiasts, and it's true...... Roland thought to himself.

Nitrogenitor* glycerin is extremely unstable, and Nobel's safety explosive is to add diatomaceous earth to it to passivate the ester, which improves safety but reduces the power of the explosion. Roland naturally did not opt for this classical method, and he intended to add nitrocellulose or nitrocellulose to nitrocellulose glycerin, both of which would have a stabilizing effect and further enhance the explosive effect. The former is an excellent smokeless projectile*, while the latter is a powerful explosive. As their name suggests, the large amount of nitric acid was the key to the evolution of black powder to chemical powder.

And he now has the key.
