Well, Renault admitted that the basic chemistry of Da Chu has not improved much because of Renault's arrival, except for the appearance of black powder, everything else is the same.

To be honest, Renault doesn't know much about black powder purification technology, what he found in those books is only egg white purification method, but only one word is mentioned, and Renault doesn't know how to do it, so he can only let his craftsmen keep trying.

As a result, Renault's black powder is not the best, the formula ratio is okay, and the purity is a big difference.

If the quality is not good, it can only be made up for by quantity, Mr. has very high requirements, to be two hundred steps away, penetrate the iron armor, but also to explode in the human body, forming a secondary injury, in just half a month, Mozi can come up with such a bullet, it is quite remarkable.

"Let's start the test launch. Renault said, this is not the first time to test firing, Mozi has conducted more than a dozen test firings, and the one shown to Renault is already a quite mature product.

Thanks to this treasure land, there are a wide variety of metal ores, and the barrel made of refined iron can't withstand such a charge at all, and Mozi is dying of worry just because of the heat dissipation problem.

The more impurities in black powder, the worse the thermal efficiency ratio, most of the heat energy can not be converted into kinetic energy, the result is that every shot, will emit amazing heat, such a large gun, ten consecutive shots, the gun can't hold it, it's too hot. Not even with a wooden butt.

"Shoot!" At the sound of the order, the gunfire on the shooting range was loud, the rate of fire was too fast, and the blueprint given by Renault was a five-round spring clip and a bolt-action rifle.

Similar to the Mosin Nagant and Enfield rifles, five rounds are pressed down from above, and the lower bullets are pushed up by the force of the spring, and the bolt is loaded with the unloaded cartridge case.

A slightly more skilled gunner can make 10 rounds a minute. Of course, in real combat, the rate of fire can't be so fast, you always have to aim before you can shoot.

In fact, in Da Chu really doesn't care about the problem of aiming, the enemy he faces is rushing upwards in rows, as long as the direction is correct, don't raise the muzzle too high, one by one, even if you can't hit the one you are aiming, you will hit others.

Each rifle was prepared with thirty rounds of ammunition, and Mozi did this to not only check the quality of the barrel, but also to let him understand how terrible the rate of fire of this gun was, and a hundred rounds was really not much.

In less than five minutes, thirty rounds of ammunition were gone, and no one could tell what the result was. Black powder is not smokeless gunpowder, every shot, emitted a lot of black smoke, after a few shots, there is a black fog in front of you, choking gunsmoke, not to mention the clay pot two hundred steps away, you can't see clearly a few steps away, and it's difficult to even breathe.

Renault's face was not very good-looking, he carefully observed, this gun was not only heavy, but also the recoil was amazing, a large part of the kinetic energy of the black powder was eaten up by the recoil, and the kinetic energy of the bullet was greatly reduced.

Don't look at the scary amount of charge, but the power of the bullet is not great. You must know that a bullet weighs more than 100 grams, excluding the bullet case, at least 60 or 70 grams of black powder are required, and the charge of a few bullets is about the same as that of a grenade, but the killing effect is too far behind.

After a full ten minutes, the black smoke cleared, and then looked at the clay pots in the distance, Renault's face twitched, there were hundreds of clay pots there, less than a fifth of them were shattered.

I really don't blame the gunners, they actually hit quite accurately, basically they can make the first hit, but the second shot is difficult to say, it would be good to hit half of the target, from the third shot, everyone closed their eyes and put it, anyway, it's the same whether you look at it or not, no matter how good your eyesight is, you can't see it.

Such a rifle basically meets Renault's requirements, according to the size of the bullet design gun, the range is within 200 steps, penetrating the iron armor, the bullet is armor bullet, the shot will produce secondary damage to the human body.

In addition, because the bullets and guns are very large, this caliber is a bit scary, twenty mm caliber, saying that it is a cannon Renault is believed.

But its disadvantages ......

It's sad, the gun is heavy and the bullet is heavy, the smoke is big and the power is small, and the recoil is amazing, in Renault's opinion, the recoil of the sniper rifle will not be as big as it.

In real combat, the effect of the first shot is definitely the best, and then it can only depend on luck?

This can't be done, the advantages of the gun are accuracy, long distance, and fast firing, the first benefit is gone, is the gun still a gun?

The solution?

There must be, as long as smokeless gunpowder is researched, it will be solved directly, but Renault will not. This project has been established a long time ago, and the research has been almost a year and a half, but unfortunately Renault can give too little guidance, and the knowledge of chemistry of the Da Chu people is not as good as that of the children of the child, and if they want them to study smokeless gunpowder, Renault also knows that it is difficult.

"How is the refining of nitroglycerin?" Renault sighed lightly, Mozi can build a musket to this extent, he should be content, the evolution of muskets takes tens of hundreds of years, and Mozi only took less than two years under the guidance of his half-man.

"It was blown up a few times, and a few big workers died. Mozi shook his head and said, he originally wanted to tackle this matter personally, but Mr. was not allowed, and sternly warned him that he must not touch this project.

"Okay, let's first follow this stereotype, design process tooling, and start production, especially the bullet production line, the required output is very large, no matter what method you use, within a year, at least 10,000 rifles and 10 million rounds of ammunition must be prepared. Renault thought for a moment and said.

Mozi's face is as ugly as a bitter melon, and the gun is okay to say, as long as the output of the barrel and spring is solved, 10,000 is not much, there is no shortage of materials here, and there is enough water to drive various equipment, which can be 10 million bullets......

patted Mozi on the shoulder: "Try your best to let people do it, you only need to be in charge of the process tooling, and I will send someone else to take over the production matter." ”

Renault also knew that Mozi was a technical talent, and letting him be in charge of management would only be a mess.

Leaving the shooting range, Renaud took people to the military school.

The military academy was completed and opened three months ago, and the first batch of cadets was ready-made, recruited from the convoy, a total of three hundred people. And it is a compulsory recruitment, otherwise Renault will not be able to recruit a single student.

The Great Chu people are really interesting, these guards, if you let them carry knives to kill, they won't even frown, let them take a pen to study, that will really kill them, like tiger teeth, it is quite common to get dizzy when you read a book.

Fortunately, after a few days of class, the spirit of these people came. Renault naturally didn't have time to teach them in person, so he compiled the textbooks of the military academy, the instructors were very easy to handle, Cui Qing's classmates and friends were a lot, and it was still very easy to put the hundreds of bachelors in the military academy according to the textbook.

Renault's request is very simple, read the textbook, teach according to the words on the textbook, you don't need to understand, and don't add your own opinions and understanding. If the students have questions, you just need to record them and hand them over to Renault, who will have time to answer them, and the instructors will hold special answering classes to answer these questions.

Not to mention, the effect of Renault's actions is not bad, except for driving away a few nonsense, self-righteous bachelors, the teaching progress of the military school is not bad.

Since he came, Renault took over the class, postponed the normal teaching task, and temporarily changed it to a solution class, so that there were not many opportunities for face-to-face communication.

"Master Lei, according to what is said in the textbook, if we want to carry out a war of air-ground integration, how can we solve it in rainy days and night battles?" As soon as it was arranged, the first question was quite acute.

"Good question, there are not many night battles in the first place, and we should reduce night battles as much as possible on the premise of having superior equipment, so we must learn how to camp, defend, and warn. You haven't learned the night defense class yet, but you'll know when you do. In addition to this, there are several new types of night combat weapons that will take time to develop, and night combat will become easier at that time. Renault nodded and said, he knew that this cadet, who was originally a member of the bachelors, heard that there was a military academy here, and actually surrendered his identity, became a cadet, and wanted to lead the troops to fight.

"As for the problem of rainy days, it is more complicated, in such weather, it is not suitable for combat in the first place, we will be difficult, but the enemy is even more difficult......"

Renault's answer, the students carefully made a transcript, if the military experts on the earth heard it, they would be able to laugh off their big teeth.

There is no way, Renault is a college student, not even a military enthusiast, and he uses gunpowder weapons that have long been obsolete, and it is not easy to take the problem into account at this depth.

When Renault was instructing the students, Cui Cheng took Luo Ning, plate armor, and riding a gun, and crossed over to find General Wei's house, the conditions here are still very simple, even if he is a general, there is only a single room with a small area.

Cui Cheng's report is very taboo, even in the Shengong Palace, it is easy to cause problems, let alone a department like the Ministry of Industry.

But Cui Cheng couldn't help it, several colleagues were not optimistic about the plate armor, and Qiu Shangshu directly reprimanded. Cui Cheng complained to Cui Qing, Cui Qing told him to find General Wei directly, if he can't work in the Ministry of Industry, with his uncle's experience as a doctor in the Ministry of Industry's workshop, come to the Shengong Palace, Mr. will definitely raise his hands to welcome, now the Shengong Palace, the lack of people is crazy, and it is not enough to send as much, and an experienced doctor like Uncle will inevitably be reused.

With this back road, Cui Cheng still hesitated for five days, and finally gritted his teeth and decided to fight, it's a big deal, come to the Shengong Temple to work, change to another place, Cui Cheng has this thought, it's useless, who dares to snatch people from the mouth of the Ministry of Industry, can't kill you!

The Shengong Temple is different, there is a Lei Master, who dares not to give it to the person he wants?

It was still through Luo Ning's identity that Cui Cheng saw General Wei, otherwise he was a workshop doctor, and the general's guards would not let him go at all.

Luo Ning is different, don't look at the fact that she has not been in the Shengong Hall for a long time, but her reputation is loud enough.

The general leader of the 21st project team of the craftsman camp laboratory of the Shengong Temple!

Anyway, when this name is spoken, everyone who listens to it is dizzy, the ghost knows what kind of official position this is, not to mention, with the name of the Shengong Temple, everyone has to look up to it.
