After Hou Pai and Cheng Shaowei made the conveyor belt, Liang Shuopeng's new step to make a gun plan has reached a milestone.

At present, Liang Shuopeng has made the steel needed for the firing pin, and also used the furnace made by Robin to forge a large number of empty shells that need to be made into bullets. Then he wrote a thick draft of the bullet production process and explained it to the workers in the workshop.

Then, he invited Robin again.

"Looking for me again today, are you finished?" Robin was a little helpless. Robin felt that the problems he received from Liang Shuopeng were much more than the problems he encountered from others in a year.

However, he has to do it, everyone, including Lin Qiang, has told him that he must meet Liang Shuopeng's needs, and scientific research will always come first.

There was no way, Liang Shuopeng's request for the construction of the arsenal was naturally accepted. It's just that now the power of the People's Salvation Army has been exposed. It's a world of magic, and although most of the people still do iron cattle farming, the level of technology is quite low. However, this does not prevent this world from having magic, using magic to achieve some things by leaps and bounds.

For example, this world is not technological, so he definitely doesn't have airplanes.

But logic tells us that people will always have the need to fly, lift off and so on. So, if there are no airplanes in this world, there is no flight magic?

And then by analogy, there are certainly no reconnaissance aircraft without aircraft. There is no way to conduct aerial reconnaissance without reconnaissance aircraft. Not even planes, let alone satellites.

But who can guarantee that there is no recon magic? If there is, then it will be seen with such fanfare, on the flat land of the back mountain, to make an arsenal?

Will it be killed by a magic shot that can replace bombers or missiles?

Liang Shuopeng asked Robin about this, he didn't want the freshly built arsenal to be directly attacked by a magician. Or that the high-ranking magician of Hussein Province is more suitable. He didn't want the freshly built arsenal to be wiped out in one fell swoop.

Robin thought for a while and said to Liang Shuopeng: "First of all, I have traveled all over the world, and I have never heard of a magician who can fly directly to the sky for a long time. Of course, there may be, but I haven't heard of it. Another one, no matter how strong the magician is, the magician, the target, the staff. All three are indispensable. To put it simply, if a mage wants to cast a spell on a target, he must see the target clearly and hold a staff. ”

But even Robin explained so, Liang Shuopeng was still not at ease, Liang Shuopeng said this: "Magic may not change for hundreds of years, or even longer. That's because for the aristocracy, that's enough. But with the advent of technology, there is no guarantee that it will not change the world. So, it's better to be hidden. ”

Later, Robin and Liang Shuopeng found Lin Qiang, chairman of the Military Committee of the People's Salvation Army, who had read books and comics miscellaneously, and had a lot of messy ideas and ideas, and asked Lin Qiang if there was any good way.

Lin Qiang didn't say a word, and said directly to the temporary camp of the ink-eyed young man who was now half-abandoned: "Over there, you can't abandon it." I look at the caves very well, the caves dug before, if you don't get close to the mouth of the cave, I really can't see that there are still houses on the hillside. In addition, the black-eyed youths have basically joined the army now, so these remaining houses that no one lives in can also be used as dormitories for the workers of the arsenal. ”

Liang Shuopeng and Robin suddenly felt enlightened, and Robin even felt that Lin Qiang was an angel sent by God to save him. Because I listened to Liang Shuopeng's idea before, what kind of workshop and that workshop, what assembly line and warehouse do you have to make, I imagined that I had a difficult task.

And you say that such an arsenal also asks for secrecy. Secrecy cannot be moved to the vicinity of the open town of Cair, where the Great Plains is easy to repair, but it is too easy to be destroyed. But let's build it in the mountains, and the reason why mountains are mountains is that they are rugged. There is a pitiful lack of space, and there is such a small place, so you can't let Robin dig a tunnel.

Now, after Lin Qiang's guidance, Robin felt empowered in an instant.

However, Lin Qiang still instructed: "You remember, when recruiting workers, you must first recruit from people with mine backgrounds or Moyan tribe backgrounds. I know that recently, there are migrant workers working in the town of Chel, in the mining village, and even in the mines. However, we must not let our guard down. From a development perspective, we cannot deny the participation of the people. But we also have to beware of sand mixed with it. ”

Liang Shuopeng patted Lin Qiang's shoulder and said, "Don't worry, the candidates are all checked by Sister Xu and Sister Lingzi, and they are all old people from the mine." Not only can it be safeguarded, but it also has an industrial base, so it is easy to use. ”

Lin Qiang nodded and said, "That's good." ”

Now that things have been agreed, it is natural to do what is said. Robin deserves to be Robin, and it didn't take long for Robin to build the prototype of the arsenal. Not only was Liang Shuopeng's production line arranged, but also electrified to ensure that Liang Shuopeng's assembly line and motor, as well as lathes, could be used normally in the new arsenal.

In this world, there is no chemical industry, Robin's buildings are definitely made of the most valuable natural and environmentally friendly materials in another world, and there is no formaldehyde in nature. Liang Shuopeng quickly put the factory into use.

However, when he made the first firing pins and made the first steel bullets, he found that his semi-automatic rifle project was still one step away. That's gunpowder.

Yes, that's right, he needs a new gunpowder ratio now.

The bullet thing, he can't do it very big, it's like a cannonball, it's a cannonball, and the bullet has to look like a bullet.

It's not for the sake of pretty, but mainly for the sake of logistics, and the limit of the amount of ammunition that soldiers can carry.

If each bullet is the size of a mineral water bottle, it is not plastic like a mineral water bottle, it is steel. Not to mention bringing fifty rounds, just bring ten rounds, and it is estimated that it will cost the soldier's life.

But if you say that the bullet is the size of a mineral water bottle, how big is the gun?

If several people could only carry one gun, it would be better to use the current flintlock rifled gun.

If the bullet is small, the gunpowder is not enough, and even if it can be excited, the lethality is not high.

Paper-wrapped gunpowder projectiles, if you can't do gunpowder, put more gunpowder. But the primer of the bullet is not as much gunpowder as you want.

There was no way, Liang Shuopeng's plan to produce semi-automatic rifles came to a standstill again. I had to think about improving the gunpowder.

Modern gunpowder, especially rifle bullets, artillery shells, and grenades, is very important to the strength of gunpowder. Nitrifying gunpowder must undergo a certain chemical reaction and find a scientific ratio of sulfur and charcoal.

If there is a lot of sulfur and it burns vigorously, the gunpowder will explode. The explosiveness was too strong, and before the bullet could be shot out of the chamber, the chamber exploded and killed the gunman first.

If there is more charcoal, then it is even more useless, what is the effect of this gunpowder mixed with charcoal? In fact, it was to make the gunpowder a little more stable. When it is stable, it is not easy to be a little dry, so it will "boom" and blow up the warehouse where gunpowder is stored into the sky.

But you can't put too much charcoal. If gunpowder is too stable, what's the use? Stones are the most stable, can you still hit people with stones?

Nitrate is the most peculiar thing, it is neither a flammable substance like sulfur, nor a stabilizer, but an accelerant. Only gunpowder with a reasonable ratio of nitrate can burn more fully and have more explosive driving force.

Of course, the process of nitrification is dangerous, and if you are not careful, it will soar. Before the crossing, Nobel turned out to be a researcher of explosives, and he was almost killed.

So after Liang Shuopeng realized that he had to get gunpowder for his dream of a semi-automatic rifle, Liang Shuopeng was extremely scared. But scientists, sometimes bold and outrageous.

For example, Cheng Shaowei, if you ask him to talk to an ordinary person and take a stick to fight alone, he may be stunned. But when he invented electricity, especially DC to AC, and studied voltage to try to make the power supply of the mine more stable, he was repeatedly electrocuted and almost electrocuted. However, after recovering from this, he is still obsessed with the power industry, and he is really brave.

Of course, Liang Shuopeng is not so brave. Cheng Shaowei was able to survive repeated electrocutions, and that was because his body was intact. But if Liang Shuopeng has an accident with explosives, it is not as simple as the face being blown up like the bottom of a black pot in the cartoon, and it is estimated that he will have to become meat floss.

Therefore, Liang Shuopeng contacted the medical department, and Li Xueyuan also set up a rescue room for the R&D center. Of course, with the current medical conditions of the People's Salvation Army, it is estimated that even if it is rescue, it is to stitch him up for the trauma, and then prevent the infection and let him take sulfonamide for his life.

In any case, Liang Shuopeng is very heroic. But the demand for nitrate is getting bigger and bigger day by day, and Liang Shuopeng finally found that just by collecting manure or something, as well as mineral resources and caves, as well as the nitrate that accompanies in the mountains and forests, with a little less, with the geometric growth rate of the army, it is estimated that sooner or later it will not be enough. So, he came up with a new solution.

That's to make nitrate!

Nitrate, as the name suggests, is the field where nitrate is made. This technique first originated in the West before Liang Shuopeng crossed over. To put it simply, dig a pit in the land, get some plant ash, dung, anyway, everything that comes out of nitrate through various reactions, and bury it for a year and a half. By the next year, a large pit of nitrate raw materials can be harvested.

It's like making dough, a little yeast can make a big ball.

Although after the establishment of the People's Salvation Army, the town of Chel was conquered, and both the population and the area were greatly increased, but Liang Shuopeng could not go to poop one by one.

It can be said that the emergence of nitrate technology has laid another foundation for Liang Shuopeng's modern military industry.
