[Today's third update is delivered! ] 】

Zhao Mengji said with a little regret: "So that's the case!" ”

He also thought that Xu Xingxia was going to make a fire gun. From the point of view of these craftsmen, the profit of making firecrackers is the highest. It takes about a month to make a firecrackle from the beginning to the completion, and you can earn at least three taels of silver in the middle. However, Xu Xingxia did not need to make firearms, which inevitably disappointed Zhao Mengji's dream of making a fortune.

I really don't know, what he's going to do with this flintlock machine. Even Liu Guangliang is a little skeptical that Xu Xingxia has too much silver and has no place to use it. Since it's something you don't use, what do you do researching to do? However, when they looked at Xu Xingxia's face, they felt that Xu Xingxia was not wasting money. In desperation, both of them had to bury all their doubts in their hearts and wait for Xu Xingxia to explain themselves.

Xu Xingxia thought for a while, and said with a solemn expression: "Maybe the two of you will ask, why did I study this flintlock gun machine." In fact, this flintlock gun is linked to another technology. Now that the problem of the flintlock gun has been solved, the next step is to specialize in this technology. ”

Zhao Mengji said expectantly: "My lord, please speak." ”

Xu Xingxia said word by word: "I want to carve some rifling inside the barrel." ”

Zhao Mengji looked at Xu Xingxia, then at Liu Guangliang, and asked suspiciously: "What is rifling?" ”

Liu Guangliang also showed a puzzled look, quietly waiting for Xu Xingxia to explain.

Xu Xingxia looked around, lowered his voice mysteriously, and said slowly: "Rifling is ......"

Seriously, the word rifling is not much of a problem to interpret in later generations. That's all common sense with firearms. However, in this day and age, rifling is definitely a new word. Xu Xingxia needs to explain in detail what is a yang line, what is a yin line, what is winding, and what is a spiral, and to make Zhao Mengji and Liu Guangliang understand and understand. It's not easy to do that. Xu Xingxia must slowly weigh the words and sentences, explain in as simple as possible, and explain clearly any doubts.

In this, there is also the issue of confidentiality. In addition to explaining the meaning of rifling, it is also necessary to carefully explain the role of rifling. It is necessary to let the two of them understand it, but also not to make the two of them feel that this technology can set off a revolution in the history of firearms development, so as to generate some unnecessary ideas. Because, once this technology is spread, rifled guns will bloom everywhere. Xu Xingxia felt that at present, he did not have the ability to fully control the rifled gun technology. If the rifled gun is cloned in large numbers, he has no technical advantage.

After all, Zhao Mengji was a craftsman who specialized in the study of firearms, and his explanation of Xu Xingxia quickly captured the main point. He soon understood that this new type of rifled gun, because the bullet can rotate and fly, can fly farther, hit more accurately, and the power is much greater than any kind of firearm at this stage. The so-called rifling is used to give the bullet a spin to fly. However, this rifling problem is indeed difficult to solve.

To carve rifling on the inside of the barrel, just think about it, and find it very difficult. Anyway, with the technology that Zhao Mengji currently mastered, he couldn't do this. He conceived several options, none of which he was sure of. After thinking for a while, he said with a little embarrassment: "My lord, if you want to carve rifling on the iron pipe, you need something very hard!" We don't have anything like this in our hands......"

Xu Xingxia took out a diamond from his arms, smiled and said, "Do you think this is okay?" ”

Zhao Mengji looked at the diamond in his hand and asked a little puzzled, "What is this?" Transparent stone? ”

Xu Xingxia said lightly: "This is a diamond, which is quite hard, harder than 100 steels." I think you can use it to slit. ”

Zhao Mengji looked at the diamond in his hand suspiciously, and looked at it carefully for a moment, still looking more skeptical. A diamond, as the name suggests, is a type of stone. Stone is harder than iron, but I'm afraid it's not easy. Not to mention 100 steel. As we all know, by far the strength and hardness of 100 steels are the strongest.

Xu Xingxia said confidently: "If you don't believe it, you can try it yourself." ”

Zhao Mengji is a guy who does what he says, and immediately brought a piece of scrap iron and used diamonds to grind it back and forth. His purpose was not to scribble rifling, but to see how the diamond was worn. He really didn't believe that this transparent stone was stronger than a hundred steels.

As a result, after grinding for a long time, the diamond was not damaged at all, but the surface of the pig iron was marked with a lot of marks. Although these imprints are not very deep, they are enough to prove that the hardness of diamonds is higher than that of pig iron. Theoretically, it is indeed possible to scribble rifling.

Of course, manpower is limited. Relying solely on manpower, it is a bit difficult to carve out the rifling. However, in terms of strength, Zhao Mengji and Liu Guangliang have ways to solve it. When necessary, animal power can be used. Ningxia Town has war horses. The power contained in a war horse is much greater than that of ordinary people. If one horse is not enough, you can add a few more. As for how to solve it, that is an internal matter for the craftsmen.

Xu Xingxia said eloquently: "I estimate that the research of this technology will not go very smoothly. If you have to start from scratch, it may cost some money. Well, I'll give you a hundred taels of silver as funds for your research. You can try a variety of things to see what you need to do to get the rifling out. If you run out of funds, you can continue to come to me. In short, it is important to study the method of rifling. ”

With that, Xu Xingxia stood up, walked to the head of his bed, took out a cloth bag that had been prepared a long time ago, and handed it to Liu Guangliang. Inside the cloth bag, of course, is a silver tael of white flowers. The emperor did not send hungry soldiers, and if he wanted the craftsmen to work hard, the necessary money must be guaranteed. Xu Xingxia couldn't be clearer about this.

After handing over the silver, Xu Xingxia's expression became serious, and he said slowly: "Liu Guangliang, Zhao Mengji, the study of rifling is my personal need. Therefore, you two, you must be kept strictly confidential. No one is to tell anyone about the rifling without my permission. Otherwise, you will be severely punished. Do you know what I mean? ”

Liu Guangliang's face turned straight, and he hurriedly said: "My lord, please rest assured, we won't tell anyone, and we will definitely not leak it out." ”

Zhao Mengji also said: "Since the lord asks for secrecy, his subordinates should abide by it. ”

Xu Xingxia nodded, and said in a deep tone: "Since you understand, I won't emphasize it anymore." In case of a leak, both of you will have to weigh the consequences. Even if it's my relative, if they break the rules, I will punish them severely. ”

Liu Guangliang and Zhao Mengji had a cold spine for no reason. If these words had come out of someone else's mouth, maybe they wouldn't have been so nervous. However, when it came out of Xu Xingxia's mouth, the meaning was completely different. The guy in front of him was the one who once beat the guerrilla general Lu Yide, and he also coerced Peng Feng of thousands of households to ask him to distribute all the money and food. Such a guy is definitely not to be provoked.

The two hurriedly said again that they would never leak it out. In fact, the craftsmen of Weizhen Fort have long been untreated by their superiors, and even if they want to leak secrets, someone must be interested! In the current Ningxia Town, it is estimated that no one is willing to invest money in the research of a more powerful fire gun except for Xu Xingxia. Those are all errands of the Ordnance Bureau and the War Bureau.

At lunchtime, Xu Xingxia said to Liu Guangliang: "Uncle, you have to pay close attention to me about the rifling and don't leak it out." You are my uncle, and I trust you the most. You have to help me take care of Zhao Mengji. ”

Liu Guangliang said in a low voice: "Xia Zi, don't worry, I will." In fact, Zhao Mengji is a person, and no one likes him, otherwise, he would not have been thrown to Weizhen Fort. Even if he took the initiative to find the people above, the people above probably wouldn't see him. ”

Xu Xingxia nodded and said, "If that's really the case, I'll be relieved." ”

……

With the continuous improvement of the level of mounted archery training, the scale of the training ground has also been expanded, and the entire northern wilderness of Niujiaodun has become a training ground for the white-clothed army. To the south to Niujiaodun, to the north to Zhenyuanguan, to the west to the foot of Helan Mountain, and to the east to the bank of the Yellow River, they are all free worlds for the white-clothed army. In this area, Deng Rubai, the commander of Wei, has been assigned to Xu Xingxia for management, so he naturally regards this place as his own territory and disposes of it at will.

The soldiers of the white-clothed army can freely gallop on horseback, looking for the feeling of shooting at the Tartars. Non-commissioned officers with actual combat experience and non-commissioned officers without actual combat experience communicate with each other and pass on experience. Xu Xingxia also divided his soldiers into two groups and practiced with arrows without arrows. Whoever is shot will be out of the fight. Whichever group is shot all is declared defeated. The winning group will have an extra meal in the evening.

As the two most outstanding rangers, Mao 13 and Chi Hu became the leaders of the two groups. Xu Xingxia's task for the two of them is very simple, that is, to let their group win. As for the means, there are no restrictions at all. To put it simply, it is unscrupulous. On a real battlefield, who cares with what means? As long as you can kill the enemy, it is a useful means!

With Xu Xingxia's meaning, Mao Shisan and Chi Hu were really polite, the two of them instilled their previous skills as rangers into the minds of every soldier, which greatly enriched their actual combat experience. Since the level of the two is not far apart, the combat effectiveness of the two teams under their command is naturally not far apart. Therefore, the odds of winning in both groups are five out of five, and both have the opportunity to eat extra meals.
