But the nitrate field, which really produces nitrate, also needs time to precipitate. Why is it called a nitrate, it's similar to farming. Crops are planted in the fields, while nitrate is planted in the nitrate.

So for a while, this nitrate field can't be counted on. Liang Shuopeng wants to solve the problem of nitrate for the arsenal, and he has to rely on toilets, as well as rotten grass and trees in the mountains suitable for the growth of nitrate, etc.

The rest is to make a reasonable ratio. Nobel was blown up by the explosion back then, mainly because he started from scratch and experimented little by little with the best ratio. But Liang Shuopeng doesn't need it, he himself has crossed over, and he already has some experience in the ratio of gunpowder, and he also has it in the book.

Soon, Liang Shuopeng concocted a new gunpowder suitable for firing bullets. It's just that the new gunpowder needs to push the bullet, so the danger of the new gunpowder is also much higher than the previous gunpowder. On the other hand, Liang Shuopeng is also in the back mountain, and more safety facilities have been built. For example, the arsenal and R&D center are completely banned from smoking, etc., which makes the mountain people who are used to smoking very uncomfortable.

In the long run, there will definitely be grievances among the people. So Lin Qiang discussed with Li Xueyuan and said that he had to implement a ban on smoking, and get a propaganda that smoking is harmful to health.

Before the advent of computers and idea printing, as well as photo PS, posters were the best way to promote the word. So Lin Qiang found Zhao Huiying, the Minister of Propaganda, and worked with Li Xueyuan to study how to promote the ban on smoking.

For a time, anti-smoking posters and slogans were plastered all over the areas currently controlled by the People's Salvation Army.

For example, the classic: "Smoking is bad for your health." ”

There are also seductive: "Men who don't smoke are more attractive, and women who don't smoke are cuter." ”

And some threatening: "Every cigarette smoked is equivalent to burning a cent of one's life." ”

And so on and so forth. And now in the area where the People's Salvation Army is located, medicine is being promoted. People also have a little bit of an idea of what the organs in their bodies are. With such publicity, people are worried. There are a lot of people who have quit smoking.

However, there are not a few people who love to smoke, after all, even before the development of medicine and the development of various biological knowledge, there are many people who know that smoking is harmful, and even many lung cancers are caused by smoking, but they just don't believe in evil and smoke a lot. It can be said that the path you choose is not what others can do.

But relatively, everything has advantages and disadvantages, not smoking brings safety to the people, and what brings the mine is the control of fireworks that the mine needs for the development now. And smoking, in fact, also relieves the mental pressure of some people in the areas controlled by the People's Salvation Army, even if it is harmful to health, but the relief pressure brought by this thing is undeniable.

Of course, cigarettes, matches, including distilled spirits, as an incidental product of industry, were created, and for the improvement of people's lives in areas controlled by the People's Salvation Army, it spanned many eras, so even the people in the areas controlled by the People's Salvation Army knew that they might face a counterattack from the nobles of Hussein Province and even the entire kingdom in the future. But they did not regret it, and they did not go to the areas ruled by the nobility in search of any safety. Including the newly captured residents of the town of Chel.

The reason for this comes from two aspects, one is that there is no oppression of the nobility in this place. It's very free. On the other hand, it is also because advanced technology brings more convenient life. These people don't want to go back to the past, the dark life.

Although progress has been slow, the People's Salvation Army has gradually changed the lives of the people under the People's Salvation Army by using the technology in its hands. And the current largest scientist of the People's Salvation Army, Liang Shuopeng, finally built his own arsenal with the assistance of Cheng Shaowei and Hou Pai.

The arsenal is located in the area where the Moyan youth gather in front of the mountain behind Qingling. Using the caves previously dug by the Moyan people, the mine was further strengthened, and in some important areas it was even reinforced with reinforced concrete.

In fact, the technical conditions of reinforced concrete are not high at all, and with the mining of ore in mines, smelting can bring a large number of by-products of the iron-producing industry. For example, quicklime and so on.

This lime is stirred to form a large amount of cement that was common in pre-industry applications.

When Liang Shuopeng recommended the cement to Robin, Robin felt incredible. Because this thing is dry, it has a strong ability to shape, and it is not as difficult to use as bricks, and it is much stronger than simple wood and stone.

Especially after the construction of the steel-making furnace, it can also be smelted to produce steel bars, and when the steel bars are added to the concrete, the ability to produce this reinforced concrete is simply more than half a light.

So you say that the cave, under the force of the arch, is quite stable, plus the reinforced concrete and other fulcrums, it is really not ordinarily firm.

In this world, there is no such thing as commercial housing and real estate speculation. The house is built for use, of course, everything must be done to the best, and after the efforts of Liang Shuopeng and Robin, under Robin's estimate, the large cave of the arsenal is estimated to be easily used for a hundred years, and what will happen after a hundred years, then we will talk about it then.

Maybe a hundred years from now, when the arsenal is open on the plains, no one will dare to invade, or even if they do, no one will have the ability to invade.

The house was built, and then Cheng Shaowei and Hou sent in to build the motor and assemble the production line. And then finally the first bullets were produced.

When Cheng Shaowei and Hou Pai held the steel bullets glowing with silver light, they felt very strange. After all, the R&D center and the scientific research department of the Military Commission have been established for a long time, and Cheng Shaowei and Hou Pai have more or less some understanding of gunpowder, explosions, and the like.

Cheng Shaowei immediately asked, "Can this thing work?" If this is not wrapped in a layer of gunpowder, how can it be fired? ”

Liang Shuopeng then picked up a bullet, pointed to a circle-shaped thing at the bottom of the bullet, and explained to Cheng Shaowei and Hou Pai: "The idea of a bullet is completely different from a paper-wrapped gunpowder projectile. There is gunpowder inside the bullet itself, see this circle? Liang Shuopeng pointed to the circle at the bottom of the bullet and said.

Hou Pai and Cheng Shaowei nodded.

Liang Shuopeng continued: "Actually, this thing is called a primer. Then Liang Shuopeng took out a hand-rubbed firing pin from the small box next to him. At present, because the firing pin is more precise and has a relatively high strength, it is best to grind it with steel rather than water, so it is still hand rubbed.

Liang Shuopeng picked up the firing pin, made a gesture to go up to the bullet, and then explained: "This thing is called a firing pin, and when I turn back the new rifle, I want to remove the flintlock mechanism and change it to a trigger that connects the firing pin." Then use the trigger to pull the firing pin, hit the bottom fire, and the gunpowder inside the bullet will be ignited. ”

Liang Shuopeng then picked up the bullet, approached Cheng Shaowei and Hou Pai and said: "Look carefully, the bullet is divided into two parts, the bottom is filled with gunpowder, and the top is a bullet. When the primer is converted into heat by the kinetic energy of the impact, the bullet is fired by the explosion of gunpowder. Moreover, this shape, that is, a conical warhead, has less resistance in the air than the previous round projectile, and the speed is naturally faster and the lethality is stronger. ”

Although Liang Shuopeng's explanation made Cheng Shaowei and Hou Pai still not fully understand. But the two of them are always engaged in scientific research, as long as they are given a little time to think about it, they can understand the same.

And the firing pin and the bullet, the two most difficult parts are solved, and the rest is the barrel and the barrel.

Of course, these are not difficult for Liang Shuopeng, compared to grinding the firing pin, grinding the barrel is simply much easier. In addition, from the beginning of the flintlock pistol, the R&D center has mastered the technology of grinding rifling, and although the new barrel uses bullets, it is actually about the same.

Of course, if Liang Shuopeng is given a period of time, Liang Shuopeng can also develop a new thing, that is, the automatic unloading part of the air intake and outlet, as long as there is that thing, it can realize the continuous fire of automatic rifles, and it can also make a big killer weapon in modern warfare small arms - machine guns.

It's just that Liang Shuopeng can't spend more time studying something deeper. It took Liang Shuopeng two or three months to make steel furnaces, make firing pins, make motor assembly lines, improve gunpowder, and produce bullets. These industrial infrastructures are one step at a time, and they cannot be built overnight. And the completion of these steps is only to ensure that the semi-automatic rifle is made, and it cannot be mass-produced.

If nothing else, let's just talk about the firing pin trigger, which currently requires precision operation, and cannot be completed by relying on the current motor assembly line. It's good that thing can get a bullet.

Therefore, Liang Shuopeng's research is completely out of touch with the current training of the first, second, and third regiments. The current 1st Regiment, 2nd Regiment and 3rd Regiment have absorbed the three-stage tactics developed by the company commander under him when Hal was still the battalion commander, and are intensively using the flintlock rifled guns in their hands to carry out three-stage training.

And the surrounding area of Chel Town, because in the opinion of Lin Qiang and others, there is no moat without a city wall, and it may not be useful in the face of long-distance large-scale magic attacks, so the moat is released on the spot and changed to a trench.

Who built this trench, of course, Robin's Ministry of Construction. It's just that the Ministry of Construction has set up a shelf, and it is no longer necessary for Robin to personally run back and forth with the firefighters. There are already new members of the civil engineering team together, and some of the responsibilities can be shared.

Most people in this world belong to the master and have to hide them, and they can't study all their ideas and ideas. But this situation is completely non-existent in the entire PLA-controlled area.
