Perfect speech!

Lu Shan suddenly gained the recognition and support of military industry experts and students in the audience. He had extensive knowledge, wise eyes, and in-depth explanations. Although there was no substantive matter involved, it laid a theoretical foundation for the subsequent work of the institute!

The three words "simple, practical and reliable" have become the most basic principles of research and design in the institute!

It is to design a "simple, practical and reliable" weapon!

After the meeting, Lu Shan convened many researchers to stay and gave another lesson. This lesson also talked about weapon design.

But the requirements are higher.

"Adapt to local conditions, self-reliance, control costs, and be people-oriented!" Lu Shan condensed the content of his speech in these sixteen words.

Adapting to local conditions is easy to explain, that is, looking for suitable materials based on one's own situation. If possible, you can temporarily replace them with relevant poor materials or find more suitable materials.

Not to mention the meaning of self-reliance. Don’t expect to buy raw materials for producing weapons from outside. Everything is done by yourself, mainly by yourself.

Controlling costs is a considerable topic, involving all aspects and requires systematic research. Saving does not mean reducing the performance of weapons. You can work hard to improve production processes and improve production efficiency, as well as reducing defective rates, as well as providing equipment utilization, reducing wear, etc.

On the one hand, if you save a little, the savings will be considerable.

People-oriented, this is what Lu Shan wants to emphasize. Not only should the design and use of weapons take into account the user's factors, but also ensure the nutrition and rest of the researchers in research work.

Only after eating well and resting well can you have a fuller spirit and enthusiasm to devote yourself to your work!

Lu Shan's speech moved many people. He has been in exile in China for more than ten years and has never felt so valued and cared for. Many people burst into tears on the spot and expressed that they would work hard and contribute their strength to the military undertakings of the East Anti-Japanese War.

In addition, Lu Shan also announced one thing. That is, the Light Firearms Research Institute does not call this name to the outside world, but a code name: 601.

In the future, the name of the Light Firearms Research Institute will not be allowed in all work and conversations, and the name 601 will be replaced by the name. This is also for the need for confidentiality. This is gathered here for the purpose of doing so. Not only will the Japanese be interested, but the Soviet Union will not let it go. After all, these people have worked for them. Now in the eyes of the Soviet Union, they are traitors. If they serve other countries and pose a threat to themselves, they will use the means of Gru and Ukraine, and they will execute the parties involved without hesitation.

In order to protect the institute and to protect these Belarusian experts, some keywords that can cause doubt must be removed, so that the enemy will be confused.

There was already a 701 institute, which was the research direction of password listening, deciphering and communication, while 601 was the research direction of light firearms. These two institutes are only preliminary, and there are also research institutes with code names such as 501 and 401 in the future. Of course, their functions are different!

Military industry experts are all busy, and Lu Shan just briefly said that these people are very smart and will naturally understand what they mean and don’t need to explain more.

Moreover, Lu Shan’s itinerary cannot be completely certain. Once there is a situation in Harbin, he has to rush back immediately.

Lu Shan and Ivanov once again came to the light firearm depot, where the four students Ivanov led, Su Quan, were busy inside.

He left without finishing reading last night. He was most concerned about the design and trial production of the automatic rifle that he hadn't had time to watch!

Automatic firearms are extremely powerful and are also under a considerable pressure on the logistics support of war. Therefore, for the current Dongkang, automatic firearms are not suitable for large-scale equipment.

Of course, there is no country in the world that has equipped automatic firearms on a large scale. Most countries are still developing semi-automatic rifles. It was not until after World War II that automatic firearms were able to develop rapidly!

It can be said that this gun is ahead of the world's highest-level generation!

Therefore, Ivanov kept the most confidentiality of this gun. Everything was done by him, even part of the processing of parts. If he couldn't complete some parts by himself, he would ask someone to help with the processing. However, the person who processed the parts did not know the use of the parts, only knew the drawings and sizes of the parts, and also had to sign a confidentiality agreement, etc.

Once the parts are processed, they will be locked into an extra-large safe with the files, which can be said to be the biggest secret of the entire research institute.

Only Ivanov himself knew this automatic rifle with the temporary "May 4th" type, and even his four students did not know it.

"Su Quan, you four will put down your work first and avoid it!" Ivanov ordered.

Su Quan and the other two looked up in surprise. Teacher Ivanov had never done this before. What's going on?

"Why are you still standing there? The conversation between the teacher and Commander Lu involves confidentiality. You are not suitable for being there, do you understand?" Ivanov explained.

"Yes, teacher!" Su Quan then understood, quickly took off his gloves, tidied up, and quickly left the workbench!

"Mr. Liu comes in, everyone else stays outside!" Lu Shan turned his head and ordered.

Liu Shao felt unspeakable excitement. When talking about the secret, Lu Shan left his secretary and staff outside and called him alone. What kind of trust is this?

"Lu, I have set up a separate small room here, please!" Ivanov took Lu Shan and the others to walk inside!

An iron small door, although it is a simple password lock, cannot be opened by ordinary thieves.

After entering the password, the three of them walked in together!

Ivanov turned on the light switch on the wall, and the room suddenly became bright. There was a workbench, a simple camp bed, and an iron safe under the workbench.

The workbench is very neatly tidy, and most of the piles of books are placed next to it.

Behind the iron door was Ivanov's studio clothes, with oil stains on it. It was obvious that this was left by long-term contact with metal parts, and the smell of heavy gun oil.

Ivanov walked over and turned on the lamp on the workbench, and the entire workbench suddenly became bright.

There is no natural lighting here, but a closed small house, so there must be electric lights or other light sources.

This is for the need for confidentiality, working in such a sealed room is a very huge test for people's willpower and endurance!

Of course, Ivanov is not a prisoner. He can enter and exit freely. When he is tired of work, he goes out to breathe free air, which is also a kind of enjoyment.

"Is this where you work?" Lu Shan asked.

"I stay here most of the time, and sometimes I'm unhappy when I go back, so I sleep here!" Ivanov explained.

"Well, Ivan. Pay attention to your health!" Lu Shan reminded.

"It's okay, I'm in great shape. Haven't you seen me much younger than before?" Ivanov said proudly.

Lu Shan smiled: "What do you want to show me?"

"By the way, here!" Ivanov squatted down, pointed his hand at the safe, and explained.

"How did you get such a big guy?" Lu Shan asked strangely.

"This big guy was originally posted by Fengtian Arsenal. He was taken out by the workers. After we took out the drawings and information, I brought them back. For this, Director Liang and I almost started fighting!" Ivanov said.

"You fight with Lao Liang?" Lu Shan was surprised. Lao Liang was quite generous and knew that Ivanov would not want this safe because of personal reasons. Why was it so intense?

"Yes, he said he needed this safe to keep the drawings and materials they brought from the arsenal. These materials and materials are very important to them and will be very troublesome if they are damaged. I said that the materials are not very important, and I can copy as much as he wants, so we two started arguing!" Ivanov explained.

"Lao Liang is not a person who easily admits defeat. How did you convince him?" Lu Shan asked with a smile.

"I just said, you put all these materials and drawings in my research institute. First, we can study the technology of your arsenal, and second, we can also help you keep these materials. It is indeed unsafe to put them in your place!" Ivanov said.

"Well, this is a good proposal. Such important information and drawings are placed on the construction site. Even if there is such a safe hidden in it, it is not safe!" Lu Shan nodded, "Did he agree?"

"He agreed, but asked me to sign a guarantee letter to ensure that I would not lose a piece of information and a drawing, otherwise I would have to accompany him on double payment!" Ivanov said.

"Give it two portions?" Lu Shan didn't quite understand. The information and drawings were not something to eat or use. Isn't it enough to pay one portion? Isn't it just a copy of one portion? Is this meaningful?

"It's just to pay for two design drawings!" Ivanov said.

"Oh, I understand. He wants you to design a gun for the arsenal!" Lu Shan understood. This is a sure profitable deal.

If he lost nothing, Lao Liang also made money. At least he didn't need to worry about the custody of these materials. Ivanov had to pay for it, and he had to pay him double. In other words, if he lost a design drawing, he would get two copies back and make another profit!

But one is willing to fight, the other is willing to be beaten, and each is going to win, which is a win-win situation!

"Hurry up and open the safe. I can't wait to see what's inside!"

"Oh, I'll be here soon!"

Ivanov possessed himself, turned the password lock on it, and then pointed it one by one, and finally heard a slight "click" sound, which was the sound of the password lock being untied!

Ivanov slowly opened the safe door, revealing the true appearance inside!

A row of guns was exposed, exactly the same as Lu Shan’s memory, except that most guns only had a part, not fully assembled, only three guns, which were complete and assembled.

Ivanov reached out and took out the three assembled guns: "Lu, according to the creativity and drawing design you provided, I made these three guns. These three guns, two of which were 7.62mm rifle bullets, and one of which was 6.5mm rifle bullets, just like the Japanese Army's Type 38!"

"Oh, the barrel lengths of these two guns seem to be different?" Lu Shan picked up one and compared it with the other one.

"Yes, this one is relatively long, has a long range and a slightly higher accuracy, but I found one of the biggest weaknesses of this gun!" Ivanov said.

"What?"

"Although I haven't had time to test the gun, I feel that the weight of this gun is probably a big burden for ordinary soldiers!" Ivanov said.

"You mean the gun is too heavy?" Lu Shan said.

"Yes, it is more than one kilogram heavier than the weight of the same rifle now. One kilogram is about the food ration for a soldier to carry for two days. If he marches with a load, it will inevitably increase the burden!" Ivanov said.

"This problem is not difficult to solve. The weight-bearing problem can be solved through training. The army's weight-bearing level can be improved. Besides, in future wars, we have cars, armored vehicles, and tanks. The weight-bearing of soldiers themselves can be reduced through other methods, so the problem of increasing combat weight-bearing is not big!" Lu Shan explained.

"There is another issue of bullet caliber matching. The bullets we use now are generally 7.92mm and 6.5mm rifle bullets, with most Japanese weapons, so our bullet production and reinstallation are mainly 6.5mm. So, I improved the design so that this gun can use 6.5mm rifle bullets!" Ivanov explained to the third gun.

"Well, what is the theoretical coefficient?"

"It's a little worse, mainly because it's not as good as 7.62mm in terms of lethality and reliability!" said Ivanov.

"Why didn't you build a 7.92mm?"

"I thought about it too, but Lu, the number you gave me is too accurate. The 7.62mm caliber is the most perfect. If the 7.92mm caliber, it will increase the weight of the gun and increase the power, but the shooting accuracy will decrease!" Ivanov said.

In fact, which size is the best for the caliber of a rifle bullet? Early-moving rifles are affected by technology and ammunition performance. The large caliber has a huge power and the range also occupies a large factor. Within an effective combat distance of 300 to 900 meters, a more powerful bullet is naturally chosen.

"Mr. Liu, what do you think?" Lu Shan turned his head and asked Liu Shao.

"Mr. Lu, I have never seen such a gun. I don't know how it performs, but it seems that it is a gun that has never appeared in the world!" Liu Shaofu was a little excited.

"Liu, you are right. This is the world's first automatic rifle. Now it is temporarily in the May 4th. These three are sample guns I tried first. Some of them need to be tried out below for testing!" Ivanov said, "In addition, this gun is designed by Lu. I just helped to improve and manufacture it. It uses a bolt slewing lock. This is a brand new architecture. Its reliability is really amazing!"

"This, was this gun designed by President Lu?" Liu Shaofu was stunned.
Chapter completed!
