Well, Renault admitted that the basic chemistry of Dachu has not been greatly improved because of Renault's arrival. Except for the emergence of black gunpowder, everything else is the same.

To be honest, Renault didn't know much about the black gunpowder purification technology. He found only the egg white purification method in those books, but he only mentioned a word. Renault didn't know how to do it, so he could only let his craftsmen try it constantly.

The result is that Renault's black gunpowder is not the best, the formula ratio is OK, and the purity is a lot worse.

If the quality is not good, it can only be compensated by quantity. The teacher’s requirements are very high. He has to penetrate the iron armor at two hundred steps away, and explode in the human body, causing secondary damage. In just half a month, it is already quite amazing that Mo Zi can take out such a bullet.

"Start the test shot." Renault said. This is not the first time he tested it. Mozi conducted more than a dozen test shots, and the one he showed to Renault was already a very mature product.

Thanks to this treasure land, there are a wide variety of metal ores. The barrel made of fine iron can't withstand such a charge. Mo Zi was almost worried about the problem of heat dissipation.

The more impurities of black gunpowder, the worse the heat efficiency ratio. Most of the heat energy cannot be converted into kinetic energy. As a result, every shot is fired, it emits amazing heat. Such a large gun can't hold the gun even if it shoots ten times in a row. It's too hot. Even with a wooden butt stock, it won't work.

"Shoot!" With the command, gunfire sounds on the shooting range, and the rate of fire is too fast. The drawings given by Renault are five-round spring clips and bolt-action rifles.

Similar to the Mosinnagan and Enfield rifles, five bullets were pressed down from the top, and with the power of a spring, the bullet below was pushed up and bolted the bullet backing shell to bounce.

A more skilled gunman can make ten bullets per minute. Of course, in actual combat, the rate of fire cannot be so fast, you have to aim to shoot.

In fact, in Da Chu, I really don’t care about aiming. The enemies I face are rushing upward in rows. As long as the direction is right, don’t lift the gun too high. One by one, one by one, even if you can’t hit the one you aim, you will hit other people.

Each rifle has prepared thirty rounds of bullets. Mo Zi did this so that the quality of the barrel can be checked, and at the same time, it also makes the gentleman understand how terrible the firing rate of this kind of gun is. There are not many 100 rounds.

In less than five minutes, thirty bullets were exhausted. As for the result, no one could tell. Black gunpowder is not smokeless gunpowder. Every time he shot, there was a lot of black smoke. After a few shots, there was a black fog in front of him, and the choking smoke. Not to mention the pottery jars two hundred steps away, they couldn't see clearly even a few steps away, and it was difficult to breathe.

Renault's face was not very good-looking. He observed carefully that the gun was not only heavy, but also had an amazing recoil. A large part of the kinetic energy of the black gunpowder was eaten by the recoil, which greatly reduced the kinetic energy of the bullet.

Although the amount of charge is scary, the power of the bullet is not very high. You should know that a bullet weighs more than 100 grams. Apart from the shell and bullet, it takes at least 60 grams of black gunpowder. The charge amount of a few bullets is almost the same as a grenade, but the killing effect is far inferior.

After ten minutes, the black smoke dissipated. Looking at the clay pots in the distance, Renault's face sucked. There were hundreds of clay pots there, less than one-fifth of them smashed.

It's really not the Gunners. They actually shot very accurately. They can basically hit the starting lineup, but the second shot is hard to say. It's good to have half of the target hit. After the third shot, everyone just closed their eyes. It's the same whether they look at it or not. No matter how good the eyesight is, they can't see it.

Such a rifle basically met Renault's requirement, designed the gun according to the size of the bullet, with a range of within two hundred steps, penetrated the iron armor, and the warhead was made of armored bullets, which would cause secondary damage when shot into the human body.

In addition, because the bullets and guns are both large, this caliber is a bit scary. Even Renault believes that it is a gun with a caliber of 20 mm.

But its disadvantages...

It's so 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 is not as large as it is.

In actual combat, the first shot must be the best, and then it depends on luck.

This is not true. The advantage of a gun is accuracy, long distance, and fast shooting speed. The first benefit is gone. Is that gun still a gun?

The solution?

There must be one. As long as smokeless gunpowder is developed, it will be solved directly, but Renault won't. This project has been established for almost a year and a half. Unfortunately, Renault can provide too little guidance. The people of Dachu have a better understanding of chemistry than children of childish people. If they want them to develop smokeless gunpowder, Renault also knows that it is difficult.

"How is the refining of nitrifying glycerin?" Renault sighed softly. It was time for him to be content with Mo Zi being able to build a musket to this level. It took dozens or hundreds of years for the musket to evolve, and under the guidance of his half-baked man, Mo Zi only took less than two years.

"It exploded a few times, and several major workers died." Mo Zi shook his head and said. He originally wanted to solve this problem personally, but the teacher was not allowed to do so. He sternly warned him that he must not touch this project.

"Okay, first, design the craftsmanship and start production, especially the bullet production line. The required output is very large. No matter what method you use, you must prepare at least 10,000 rifles and 10 million bullets within a year." Renault thought for a while and said.

Mozi's face looks as ugly as a bitter gourd. It's okay to say that the gun is produced by the barrel and spring. There are not many ten thousand pieces. There is no shortage of materials here, and there is enough hydraulic power to drive various equipment, which can produce ten million bullets...

Pat Mozi's shoulder: "Try to make the best of you, you just need to be responsible for the craftsmanship and work clothes. I will send someone else to take over the production matters."

Renault also knew that Mozi was a technical talent, and letting him be responsible for management would only be a mess.

Leaving the shooting range, Renault brought his men to the military academy.

The military academy had completed and started three months ago. The first batch of cadets were ready-made and recruited from the guards, totaling 300 people. Moreover, it was recruited for compulsory purposes, otherwise Renault would not be able to recruit any cadet.

The people of Da Chu are really interesting. If you ask them to kill people with a knife, you won’t even frown. If you ask them to learn with a pen, it will really cost them their lives. It is quite common for them to get dizzy when they read books.

Fortunately, after a few days of class, these people were energetic. Renault naturally had no time to teach them in person, so he compiled military academy textbooks, which were easy to handle. Cui Qing’s classmates and a lot of friends. It was easy to put those hundreds of bachelors in the military academy to read the textbooks.

Renault’s requirements are very simple. Look at the textbook and 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. Renault has time to answer them, and the teachers will give them special answers and answer these questions.

Not to mention, Renault's performance in this way was pretty good. In addition to driving away a few bachelors who were talking nonsense and self-righteous, the teaching progress of the military academy was pretty good.

Since he is here, Renault takes over the class, pushes back the normal teaching tasks and temporarily changes them to answering classes, so there are not many opportunities for face-to-face communication.

"Master Lei, according to the textbook, we need to carry out a war of integrated air-grounds. So how can we solve it in rainy days and night wars?" As soon as the arrangement was made, the first question was quite sharp.

"Good question, there are not many night battles. We should minimize night battles as much as possible under the premise of having advantageous equipment, so we must learn how to camp, defense, and early warning. You have not learned the night defense class, but you will know when you learn it. In addition, there are several new types of night battle weapons that take time to develop, and night battles will become easier at that time." Renault nodded and said, knowing that this student was originally one of the bachelor's students. He heard that a military academy was opened here, but he actually reduced his status and became a student, wanting to lead troops to fight.

"As for the problem of rainy days, it is quite complicated. In such weather, it is not suitable for combat. We will have a hard time, but the enemy will be even more difficult..."

The students took the transcript of Renault's answer seriously, and if the military experts on earth heard it, they would laugh out loud.

There is no way, Renault is just a college student, not even a military enthusiast, and he uses gunpowder weapons that have been eliminated long ago. It is not easy to take the problem into consideration of this depth.

While Renault was instructing the students, Cui Cheng took Luo Ning and Plate Armor and rode a gun to find General Wei’s house. The conditions here were very simple. Even the general had only a single room with a large area.

Cui Cheng's report on the level of the ranks is very taboo. Even in the Shengong Hall, it is easy to cause problems, let alone departments like the Ministry of Works.

But Cui Cheng had no choice. Several colleagues were not optimistic about the plate armor, so Qiu Shangshu directly scolded him. Cui Cheng complained to Cui Qing, and Cui Qing told him to directly look for General Wei. If he couldn't work in the Ministry of Works, he would come to the Shengong Hall with his experience as a doctor in the Ministry of Works workshop. The gentleman would definitely welcome him with both hands. Now, there are so many people in the Shengong Hall that are short of people. It is not enough to send them. An experienced doctor like Uncle Lao will inevitably be valued.

With this retreat, Cui Cheng hesitated for five days, and finally gritted his teeth and decided to fight. At worst, he would stop working in the Shengong Temple. If it were something else, Cui Cheng would have such a thought. Who dares to snatch people from the Ministry of Works and can't kill you!

The Temple of Shengong is different. With Master Lei here, who dares not give the person he wants?

It was still because of Luo Ning's identity that Cui Cheng met General Wei, otherwise he would have been a doctor in the workshop and the general's guard would not have let him go.

Luo Ning is different. Although she has not been in the long run for joining the Shengong Temple, her reputation is very famous.

General head of the 21st project team of the Shengong Temple Craftsman Camp Laboratory!

Anyway, when this name is said, everyone is dizzy. Who knows what official position this is? Not to mention that, everyone has to look up to the name of the Shengong Hall.
Chapter completed!
