"The Church seems to have suddenly appeared. "
Even after returning to the office, Roland's heart was still echoing these words.
He closed his eyes and carefully searched through Prince Roland's memory, but still couldn't find any more relevant content. His understanding of the Church was similar to that of an ordinary noble – in the palace, Prince Roland didn't spend much effort on learning knowledge, and his knowledge of occultism was almost a blank. But if what Tilly said was true, then the Church's propaganda strategy was too strange.
Taking the religious legends of the original world as an example, the idea that God originated from the beginning of the world was child's play, and the idea that the world was created by God was the one that everyone unanimously chose. For example, the creation of the world in seven days, the reincarnation of karma, and so on … a complete set of legends describing the power of God was the standard for every religion.
In comparison, the Church of this world seemed quite … immature.
However, Roland didn't have any more clues to continue his research, so he shook his head and decided to put these thoughts to the back of his mind.
Perhaps after exploring the ancient ruins of the Concealing Forest, he would have all the answers.
He went to the window and looked at the huge coating that was spread out on the ground in the garden – in the vast expanse of white snow, its green appearance was particularly striking.
Now Soroya was gluing a larger air sac, and the new hot air balloon would be even larger and could carry more people. This was in consideration of the fact that if they couldn't find a way to rescue the trapped woman during the exploration of the ruins, they would simply let Anna cut the whole "ice coffin" and bring her back to Border Town along with a part of the transparent crystal.
The departure time was set for two days later.
The personnel had already been arranged. The Sleeping Island witches were Tilly, Sylvie, Shavi, Ashes, and Andrea. The Witch Union would send Anna, Vendy, Nightingale, Nana, Lightning, and Maggie. This time's lineup could be said to be unprecedentedly strong, with the highest level of attack, defense, and battlefield awareness. As long as they didn't use God's Stone of Retaliation, it would be difficult for the Devils to get close to them.
"Your Highness, Chief Alchemist Sir Kemchester wants to see you," a guard said outside the door.
"Let him in."
This time, Kyle didn't come alone, he also brought his colleague Chavez with him. "Your Highness, we already have some progress on the large-scale production of nitric acid that you requested."
"Really?" Roland was slightly startled, and then a burst of joy surged in his heart. This was probably the best news he had heard in recent days. He stood up excitedly and personally poured a cup of tea for the two chemists. "Tell me, how did you make it?"
"This is the credit of Chavez," he said, stroking his beard and smiling. "Let him explain it to you."
"Your Royal Highness," the young Chavez appeared to be somewhat reserved, he bowed and said, "Your Alchemy Workshop … No, the chemical laboratory produces nitric acid by dry distillation of saltpeter to obtain dilute nitric acid and then purify it with concentrated sulfuric acid. So I tried to combine the two together and directly put the saltpeter in concentrated sulfuric acid to heat it. As a result, I succeeded in obtaining a nitric acid solution. Moreover, the purity was very high. I could even observe the smoking phenomenon recorded in 'Elementary Chemistry'. "
"Shared heat? But the two are not the same thing, "Roland said, feeling strange." The temperature of dry distillation is much higher than that of shared heat. Moreover, the gas produced by dry distillation should be nitrogen oxide, and when introduced into water, it will form dilute nitric acid. The purification of concentrated sulfuric acid is only using the principle of its high boiling point and strong water absorption to reduce the water content of nitric acid, it does not involve a chemical reaction. "
"I don't really understand why, but Mr. Sichi later did a few experiments and thought that my discovery was a coincidence."
"A coincidence?" Roland looked at the chief alchemist.
"Indeed," Kyle affirmed, "The two are not the same, but they produce the same effect. According to the chemical formula, I deduced that it should be some component of the saltpeter and sulfuric acid that produced nitric acid, which then evaporated in the heat. According to the formula, it looks like some kind of … Well, nitrate. "
Roland's mind suddenly remembered that in the chemistry textbook, it was indeed mentioned that before the invention of synthetic ammonia, people used sodium nitrate or potassium nitrate to react with concentrated sulfuric acid to produce nitric acid. This was also the oldest industrial method. Because the main components of saltpeter were two kinds of nitrates, it was easy to obtain and extract, as long as the temperature was controlled, a steady stream of evaporated nitric acid could be collected.
Of course, because this method consumed a large amount of sulfuric acid, it was also extremely easy to corrode the equipment. Later on, it was quickly eliminated by more advanced technology.
However, these two points were not too big of a problem for Roland. His territory had not yet established a supporting fertilizer and pesticide industry, so the sulfuric acid produced was only used to purify nitric acid. As for the strong corrosiveness of the nitric acid steam, he could rely on Soroya's coating to solve it.
"Well done," Roland happily patted Chavez's shoulder, "You actually managed to come up with this method by chance."
"You may not know this, but when he was in the Redwater City Alchemy Workshop, he had already shown extraordinary luck," Kyle Moschui raised his eyebrows, "Before learning chemistry, alchemy itself is a kind of exploration that requires luck. But this kid was able to discover the double acid production method in his early twenties, and became the youngest alchemist in the workshop, causing a group of thirty or forty year old apprentices to be so envious that their eyes turned red. You have to know that for the rest of their lives, it is very likely that they will only be apprentices. "
"In any case, this is good news for Border Town," Roland praised, "You can first try to produce a batch of equipment, I will let the witches cooperate with you. If it is feasible, then we can expand the production scale. "
"As you wish."
"That's right, I still have another task for you," Roland then put away his happy mood and said in a solemn tone, "Now that we have a reliable source of nitric acid, I need you to try to produce a very dangerous item – nitroglycerin."
"How dangerous is it?" Kyle asked.
"The raw material used is very simple, that is, a reaction between concentrated nitric acid and glycerin, supplemented by concentrated sulfuric acid as a catalyst, but during the reaction process you must strictly control the temperature and maintain ventilation. Because nitrification will produce a lot of heat, you can put the container in ice water to test. Remember, sudden changes in temperature, vibration, impact, and friction can all lead to an explosion. " Roland didn't know whether this amateur knowledge was reliable or not, but there was no doubt that the composition was correct, even if it was dangerous, he still had to try. "During the test, use a small amount of acid, so that even if an accident occurs, Miss Nana will be able to rescue you."
"This …" Chavez opened his mouth, but before he had the time to answer, Kyle had already agreed, "I understand, how does its power compare to Snow Powder?"
"The difference is like heaven and earth."
"It seems that it will be an interesting experiment," the chief alchemist said with a smile.
"Nine out of ten chemists are potential explosion art lovers, this is really true …" Roland thought.
Nitroglycerin was extremely unstable, Nobel's safety explosives were made by adding diatomaceous earth to passivate the ester, which improved the safety, but reduced the explosive power. Roland naturally wouldn't choose this classical method, he intended to add nitrocellulose or nitrostarch to the nitroglycerin, both of which could play a stabilizing role, but could also further enhance the explosive effect. The former was an excellent smokeless propellant, while the latter was a powerful explosive. From their names, it could be seen that a large amount of nitric acid was the key to the evolution of black powder into chemical gunpowder.
And now he already had this key.
