…

The most mysterious and secret place in Liangshan is the Gunpowder Bureau.

Seeing Li Yan helping Liu Huiniang come in from outside, Ling Zhen quickly came up and said, "Brother, sister-in-law!" Then he asked someone to bring a chair to Liu Huiniang!

After Liu Huiniang sat down, Li Yan asked: "According to the ratio I mentioned, how powerful is the gunpowder?"

Ling Zhen sincerely said: "Brother is really a god. The gunpowder arranged according to the ratio mentioned by his brother is more than ten times more powerful!"

In later generations, even a primary school student knew that one sulfur, two nitride, and three charcoal could be used to make black gunpowder.

But those who truly understand black gunpowder know that the power of the black gunpowder matched in this ratio is really average.

After hundreds of years of experiments and practices, humans have discovered that the combination ratio of black gunpowder is about 10% sulfur, charcoal accounts for about 15%, and saltpeter accounts for about 75%, which is the most suitable ratio of black gunpowder.

Although people at this time had mastered the main components of gunpowder, they were still very immature in terms of ingredients. In addition to saltpeter, sulfur, and charcoal, they also mixed them with ten ingredients such as clear oil and maru. These ingredients are mainly flammable substances. At this time, people think that this can increase the power of black gunpowder.

In fact, it is the opposite, because after adding those messy things, gunpowder becomes impure and its power is much less.

As a soldier and an excellent soldier, Li Yan learned to make explosives while in the army.

Moreover, Li Yan not only knows the production of black gunpowder, but also the production of cotton nitrate and nitroglycerin.

If it were later generations, Li Yan could make cotton nitrate by himself by going to a pharmacy. Even if he gave Li Yan a bag of fertilizer, Li Yan could tinker with powerful explosives.

Unfortunately, this was in ancient times when technology was seriously backward. At present, Li Yan couldn't even get nitric acid. How could he make cotton nitrate and nitroglycerin?

Therefore, no matter whether Li Yan wants to do so or not, Li Yan can only develop black gunpowder at present.

Li Yan personally experimented with the black gunpowder made by Ling Zhen and the others, and confirmed that its power had indeed reached the limit of black gunpowder, and said, "Get some wine."

Ling Zhen was puzzled, "What are you doing with medicine? Are you celebrating?"

However, because Li Yan had changed the formula of black gunpowder before, the power of black gunpowder increased by more than ten times, Ling Zhen had already obeyed Li Yan.

Therefore, after reacting, Ling Zhen immediately ran out and soon took a jar of rice wine.

Li Yan looked at the rice wine that was lower than the beer and thought to himself: "It's time to teach them how to make alcohol by distilling."

The degree of rice wine is relatively low, and the effect is undoubtedly worse, but fortunately it is just a little worse, not that it cannot be used.

Li Yan took a shovel of gunpowder, poured rice wine onto the gunpowder, then poured it on the copper sieve he brought, and then shook evenly to turn the black gunpowder into small particles of uniform size.

After finishing all this, Li Yan said to Ling Zhen: "Let your people make all the black gunpowder into this granular form as I did just now, then dry it, and then store it in a dry place with care."

In the field of gunpowder, moisture prevention has always been the top priority. Moreover, once the gunpowder becomes blocky, it may be difficult to ignite, let alone increase its power, so no one has ever thought of wetting the gunpowder.

It is precisely because of this that Ling Zhen’s face was full of shock and incredible!

But Ling Zhen did not raise any objection - it was the same reason. Li Yan had proved that in the field of gunpowder, he was far better than Ling Zhen, so Ling Zhen only respected Li Yan, and even blindly followed him without any doubt.

Li Yan didn't explain anything to Ling Zhen either.

First of all, it takes too much time to explain something, and what Li Yan lacks the most now is time.

Secondly, it doesn’t make sense to explain it or not. Having the best ratio of granular black gunpowder is already the limit of black gunpowder and there is no greater room for development.

Again, Li Yan, who had not finished studying in junior high school, only knew that the power of the particles of black gunpowder was several times that of powdered black gunpowder, and it was not as easy to get damp as powdered black gunpowder, and it was more convenient to load. As for what principle it was, Li Yan actually couldn't explain it clearly. After all, Li Yan was not a researcher, and the old squad leader who taught Li Yan's blasting back then did not tell Li Yan the principle.

Again, keeping the mystery helps Li Yan's rule.

After Li Yan finished talking to Ling Zhen about the precautions, Liu Huiniang unfolded the drawings she brought and said, "This is the water wheel stone mill and water wheel copper sieve I developed. The real thing is in my studio. If you go back, you can send someone to move it. With them, you should save a lot of effort, but you must pay attention to moisture protection. The water wheel stone mill and water wheel copper sieve cannot be far away from water, and gunpowder is afraid of water."

Ling Zhen took the drawings and said, "Okay, sister-in-law, I'll send someone to move in a while and then produce as much gunpowder as possible."

Li Yan said: "Don't ignore quality because of quantity."

Ling Zhen said: "I have set off fireworks for the official family for ten years, and I know the importance of gunpowder quality."

Li Yan nodded and said, "After the granular black gunpowder is dry, I will start making the thunder and explosive packs I told you last time. I have told Military Secretary Wen that he will organize a thousand people to help you make these two firearms, but they are all old, young, women and children. They don't understand the terribleness of these two things. You must pay attention to safety at that time. I don't want to die before the war begins."

Ling Zhen said solemnly: "Brother, don't worry, I have seen my friend killed by himself, and I will never let this happen in front of me again!"

Li Yan nodded and asked again: "I asked you to train the gunner, how are you training?"

Ling Zhen smiled bitterly and said, "Brother, it's not that I'm shirking my responsibilities. We don't have any gunpowder, how do I train me?"

Li Yan also knew that this was a bit difficult for Ling Zhen. After all, there was nothing to do now, and it was indeed difficult to train.

Li Yan retreated and looked for the second best, saying: "You take the time to go to the reserve to pick two clever people to form the framework of the artillery battalion first, and then teach them the precautions of the gunners. Before the war, I will definitely let you have artillery. Then you will take them to assault for a few days... Brother, in this battle, you and your artillery battalion will be the key to the victory or defeat. Liangshanbo's eight or nine thousand lives are all tied to you!"

Ling Zhen straightened his back and said, "Don't worry, brother, Ling Zhen promises not to let his brother down!"

Li Yan patted Ling Zhen on the shoulder and said, "When picking people, tell them clearly that cannons are dangerous, let them join voluntarily, and then tell them that their monthly money is twice that of Ma Jun."

The cannon produced by Li Yan is quite powerful, but it is easy to explode. Especially when he was inexperienced at the beginning of the establishment, he was completely using his life to fire his guns. Therefore, Li Yan himself felt sorry for not giving them higher treatment.

Ling Zhen said: "Is there no danger in joining the army? Brother, what exactly is our cannon like?"

It is also time for Ling Zhen to meet his closest companion in the future, so Li Yan said: "Let's go, I'll take you to see our cannon."
