At that time, both the West and the East used black HUO medicine, so everyone faced the same problem, that is, if the gunpowder was left unused for a long time, the various substances in the gunpowder would be layered according to their own density and weight. It's like a jar of muddy water standing still, it will slowly separate into the bottom stone, the upper layer of coarse sand, the upper layer of thin mud and the top layer of clear water. The same is true of gunpowder, which will slowly flow on its own when it is standing still, separating the raw materials and eventually causing it to lose its effect.

The first to discover the secret of gunpowder granulation is said to have been sailors on whaling ships. It is said that the powder keg on the ship was soaked with water due to poor storage, so when the water evaporated, the gunpowder condensed together and became a large lump. Because the sailors had no extra gunpowder, they had to break up the solids formed by the gunpowder and crush them into small particles for use. As a result, I didn't expect the effect of granular gunpowder to be unexpectedly good! With the same charge as before, the range of the whaling fork is even longer!

The reason for this is actually quite simple. Because the combustion of gunpowder requires enough air, and there are more gaps between granulated gunpowder, a large amount of air is contained in it, which is convenient for the full combustion of gunpowder. Make gunpowder burn faster and with more power! On the contrary, powder gunpowder of the same weight cannot be fully burned due to lack of air, and the force is small. Since then, Westerners have been using granular gunpowder. And with the progress of Western chemical research, the accuracy of the black HUO drug ratio is getting higher and higher, and the East is gradually left behind.

After finishing speaking, Liu Pei looked at the old man and asked, "What's the matter with this old man?" The old man looked a little pale, and at first glance it was the result of years of malnutrition. The eyebrows are thick and thin, but the gaze is very firm. Wrapped in a hairless sheepskin jacket, his body looks thin, but the muscles and bones in his hands are prominent, and he has a lot of strength at a glance!

Qi Qitao said: "His surname is Wu, and his name is Wu Jinshan. This is a veteran of our guardhouse. I once fought with Qi Dashuai back then! Because none of us here know how to train sword and shield soldiers, I asked my father to ask about it and invite him later! 2 taels of silver a month plus five buckets of grains! ”

Liu Pei nodded and said with a smile: "It can be seen that Daddy Wu has a good knife." It's especially exciting when you hit someone! Qi Qitao and the two also laughed.

Wu Laohan blushed and explained: "Master Liu is laughing at the little old man!" In fact, Xiao Lao'er practiced swords and shields in the army back then, and he still knows a little bit about how to train swords and shields. ”

Liu Peike knows that there is a treasure in the family. He asked, "Uncle Wu, I don't know how to practice sword and shield soldiers, so I just want to ask, is it good to practice the Fa like ours?" Do you want to hire a martial artist to teach martial arts? ”

Wu Laohan pursed his lips and said: "This sword and shield soldier is in the front row on the battlefield, and it is a matter of time to kill or be cut down!" If you are fast, you will live, and if you are slow, you will die! Everything else is useless! As long as you practice the few strokes I taught, you can form a formation and stand firm when you go into battle, and there are pikemen in the back, and there are firecrackers to shoot, and no number of people can break through! ”

Liu Pei nodded again and again after hearing this, and said, "Uncle Wu is right! In this case, please ask Uncle Wu for this matter of training sword and shield hands. As long as they practice well at the end of the month, Uncle Wu's monthly salary will be doubled! ”

Uncle Wu was pleasantly surprised when he heard this, and said loudly: "Master Liu, don't worry, the little old man must train them seriously!" This time of meat, even Qi Dashuai's soldiers can't get by, if they don't practice well, Xiao Lao'er will be very beaten! The crowd burst into laughter.

Liu Pei continued: "By the way, the firecrackers also have to practice hand-to-hand combat. I have a set of bayonet tactics that I will teach you later. ”

The bayonet method of warfare that Liu Pei said was the bayonet technique he learned in the army. Since the establishment of our army, it has been in a state of underarmament. Therefore, the bayonet has always been one of the main tactics advocated by our army. After years of improvement, the bayonet technique of our army has been relatively perfected. Because these techniques are actually honed in battle! It was summed up with the lives and blood of the warriors! Quite practical and awesome!

Because the Ming army did not have bayonets on their firearms, they often had to carry a waist knife or dagger when fighting, which was very heavy and cumbersome. In this regard, compared to Liu Pei, the Suifa pistol they used was much worse.

Wu Yizhou said: "There is one more thing that the family should hurry up and find a way. It's just that we don't have enough gunpowder and lead. ”

Liu Pei said in surprise: "It's not enough so soon?" I remember saving quite a few of that! ”

Wu Yizhou said: "If you practice according to the training method in the guard, I'm afraid there will be a lot left now." However, according to the instructions of the head of the family, he should shoot live ammunition ten times a day. This is not enough to use. Some of the lead can be recovered, but the gunpowder is running out! ”

Liu Pei sighed and said, "It seems that we have to build another workshop!" In this case, you can send someone to the county to inquire about it, find those who can make fireworks, and see if you can hire a few people to come back and help us make the medicine. By the way, I did both the ordering of the sub-medicine and the granulation of gunpowder. However, this workshop was to be built a little further away from the village, so as not to have trouble. ”

Wu Yizhou nodded and said, "That's okay." I'll go there myself tomorrow. But you have to talk to Uncle Qi about building a workshop in the village. If you ask him to help, you can hurry. ”

Qi Qitao said with a smile next to him: "My dad can't help much faster!" Almost all the young people in our village have come to take charge! If you want to hire someone again, you have to run far. Or maybe it's built in another village? ”

Liu Pei shook his head and said, "No! The stakes are high in the medicine workshop, where can it be placed in someone else's! It's better to keep it under our noses. If it is not possible, recruit workers from among the homeless. There is always no shortage of people to do the work. “

So they took some more counsel, and then they dispersed. At this time, Liu Pei especially missed the logistics staff when he was in the army. What a blessing it was! Someone has someone ready for everything you want, you just need to practice seriously, and you still need to worry about this and that. So Liu Pei now especially hopes to have a qualified logistics helper.

Not to mention, Liu Pei really figured out a person to choose. But whether this person agrees or not is a matter of two things. Liu Pei felt that a good way was needed to lure him over. But what Liu Pei didn't know was that while he was pondering others, there were also people pondering him.
