Special Forces: At the beginning, An Ran pulled him to get his certificate.

Colonel Wang had been looking at Chen Jun coldly. He suddenly said, "Engineer Chen, is this man reliable? These weapons are carefully developed. We have tested them so many times and found no problems. How can he find problems?"

He lowered his voice, not wanting Chen Jun to hear.

"No, I still say that. The soldiers you arranged for the test have not experienced war. Real weapons should be tested by soldiers on the battlefield. They know better how to use weapons to kill people." Dr. Chen looked at Chen Jun with a serious look in his eyes. "In my opinion, no one is better than him. I have talked to him. He has more experience in weapons than me."

"He is more experienced?" Colonel Wang said with disdain on his face, "If he is so powerful, he should not be hiding here and taking a half-month vacation. He should be on the first line of defense, ready to fight at any time."

No one knew what Chen Jun’s identity was, but Colonel Wang had been waiting at the hacker base for half a month.

So in his opinion, even if Chen Jun had saved Mr. Chen before, Dr. Chen had a special status, and if the country stepped in, he would just bring people to bring him back.

Wang Xun usually hides in the Longmai base. He is the bodyguard captain of those scientific research experts, so naturally he doesn’t know about the fierce battle taking place in the slums.

But after hearing his tone, Mr. Chen's face turned cold and he told him coldly, "I don't want anyone to question his words anymore. This is a great disrespect to Captain Chen. He is the best soldier I have ever seen. In the corner you can't see, he silently guards the peace. Otherwise, we scientists would not have such a stable environment. Including you, we are all under his protection, you just don't know it."

"I am under his cover?"

Wang Xun looked at Chief Engineer Chen in confusion, suspecting that he had heard it wrong. He didn't understand what this sentence meant.

Chief Engineer Chen did not maintain his composure this time. He looked grim and said coldly, "Next time, if I hear you disrespect him, I will report it and replace the security team."

"I... didn't mean that. Sorry!"

Wang Xun was surprised by such a stern warning. Usually, Dr. Chen was polite to everyone and he was a very elegant person.

His face looked a little ugly.

"People like An Xin are everywhere. Another person who doubts me..."

With Chen Jun's hearing, he had already heard the conversation between the two people, but he was too lazy to say anything. The colonel might think that the civil defense soldiers were the ones who made the greatest sacrifices. In fact, he was not a special forces soldier and had no idea about the danger and secrecy of special warfare operations. He should have graduated from a military academy and then sat in an office, relying on his seniority to get promoted. There were many such soldiers in the general affairs department. They had special identities and were promoted much faster than front-line soldiers.

Arguing with the office boss is like talking to a cow.

Chen Jun didn't care at all about the hatred that Dr. Chen had created for him. His mind was only on the weapon.

It has to be said that these weapons are well designed, but Chen Jun, who has just integrated a lot of high-tech skills in weapons, feels that they are not good enough, especially some details, which may be due to the rush, and are not done well enough. It can also be said that his current perspective is different, and he is not even inferior to Dr. Chen.

In particular, the integration of hacker mechanization and quantum mechanics skills, and black material research skills, has allowed Chen Jun to make rapid progress in weapons and become an expert with certain qualifications, not to mention that he has also integrated a modern electronic hacker skill.

In short, even in the field of weapons research, as long as Chen Jun is given time, he can achieve some results, and even in the future he may be no less than Dr. Chen.

Of course, in comparison, he prefers to be a pure special operations soldier.

After scolding Wang Xun, Engineer Chen stood beside Chen Jun and watched him disassemble the gun, reconnect it, and disassemble it again. As an expert, he understood the significance of Chen Jun's actions and his eyes lit up.

“He really knows guns!”

Engineer Chen kept nodding secretly and watched Chen Jun playing with his gun seriously.

In the last scene, after Chen Jun reassembled the disassembled gun, he finally stood up and stretched his waist. He had been squatting for too long and his body was numb.

"how do you feel?"

Chen Jun smiled and said, "Indeed, the design of these new weapons is very good, but the details can be improved. On the battlefield, if some details are not solved, it may cost the lives of soldiers. Therefore, I think these weapons cannot be used on the battlefield for the time being and need to be improved."

"The fatal detail?"

Mr. Chen could never have expected the answer that Chen Jun would give. Such a rejection sounded very serious.

He ran over excitedly to give Chen Jun such a mysterious gift. In fact, he just wanted to use this batch of weapons to repay him for saving his life, and then strengthen cooperation. But in the first round, he was completely denied?

He was stunned, looking at Chen Jun with wide eyes: "Can you be more specific?"

At this moment, Colonel Wang Xun, who was standing nearby, couldn't help but hear Chen Jun's pretentious words. He walked over and asked in a serious tone: "Captain Chen, I don't know what missions you have performed, but I can tell you responsibly."

"The weapons you questioned have gone through the most systematic process experiments. How can you be sure that there are fatal errors just because you assembled them for a few minutes? You haven't even fired a shot. Such arbitrary statements are really unacceptable."

He became so angry that he ignored the look from Chief Engineer Chen next to him, asking him to stop talking.

"We have personally tested it hundreds of times, and you just took a look and said there is such a big problem. Do you think it is reliable?"

"We trusted you and waited for you for half a month, and this is your attitude?"

His tone became more and more serious.

"Do you need me to tell you why?"

Chen Jun narrowed his eyes, and an extremely dangerous aura quietly settled in his eyes. The strong murderous aura was like substance, gushing out.

He stared at the colonel and said calmly, "The reason is simple. I have fought in battle hundreds of times. I have fired more guns and bullets than you have used in practice. Do you think I am qualified with this experience?"

"This one……"

Hearing such an answer, no matter whether it was true or not, Colonel Wang Xun could only purse his lips and had nothing to say. After all, someone was kidnapping him with reason, what could you say?

Are you farting?

But Chief Engineer Chen had already determined that Captain Chen was the best soldier in the country and had experienced many actual combat operations.

Therefore, Wang Xun could only remain silent, with a defiant expression to express his doubts.

Chen Jun turned his head and looked at Wang Xun who had a disdainful expression. At this moment, he didn't want to endure it anymore.

I don't know what's wrong with this colonel. He keeps finding fault with him, questioning everything he says, and having all kinds of disdainful expressions. He looks similar to that Qiang Ge in Jiuzhaigou.

He is not a good-tempered person. If others question him, there is no need to endure it. That is not in line with the national policy of peaceful coexistence.

Chen Jun's eyes were like substance. He walked to Wang Xun's side, less than a fist away, and said coldly: "Are you doubting that I have never killed anyone?"

“This murderous aura…”

After all, Wang Xun was also a soldier who was fed by bullets. He had never raised pigs, but he had seen pigs run. He immediately felt the strong murderous aura and the pervasive sense of oppression from Chen Jun. It was an invisible aura that nailed him to the ground. His hairs stood up, just like a ferocious Husky encountering a tiger that jumped out of the woods.

Blood pressure!

In an instant, Wang Xun became scared. He couldn't help but lower his head, not wanting to look Chen Jun in the eye. He felt like a mountain was pressing down on his head and it was difficult for him to breathe.

Chief Engineer Chen, who was standing nearby, saw Wang Xun's face trembling and his head almost dropping to the floor. He immediately knew what had happened and came over to separate Chen Jun and the other man.

"Captain Chen, I'm really sorry. Colonel Wang also participated in the research of these weapons. He may think that you are questioning him, so he has objections."

Chen Jun snorted coldly: "No matter what position you are in, only by humbly accepting other people's opinions can you know where the mistakes are. Living in your own world is just like living in a dream."

"That's right, that's right..." Chief Engineer Chen said, "You talk, I'm listening. I know you are an expert in this field, so I'm waiting for you here."

Chen Jun was stunned for a moment, feeling like he had hit everyone with one blow. What he said just now was too harsh. Expert Chen probably thought that what he said was that everyone here was garbage.

He immediately denied it, saying that was not what he meant and asked the other party not to misunderstand him.

Chief Engineer Chen laughed and asked Chen Jun to point out the mistakes. When he came here, he was not afraid of others pointing out the mistakes, but he was afraid that the other party would not dare to say it and would hide it. If that was the case, there would be no point in coming here today.

Hearing these words, Chen Jun was filled with respect. What he admired most was the broad-mindedness of this country's sharp sword. If he could not accept other people's opinions, Chen Jun felt that there was no need to continue today's communication.

"Captain Chen, didn't you just say that details determine failure? You have a point, but what are the specific details? I need you to list the problems so that I can correct them. To be honest, this batch of weapons was rushed."

Hearing the other party speak so directly, Chen Jun did not think too much about it. He himself was also such a straightforward person. He would say whatever he wanted to say. If he was not convinced, then they would see who was better. If he still was not convinced, then they would fight to the death.

"First of all, it's a good gun, and the idea is very avant-garde, but..."

Chen Jun picked up a pistol and said, "Your design is to lengthen the barrel so that you can switch between a pistol and a submachine gun. It seems to have many aspects and a good idea, but the biggest problem is that in order to overcome the switching problem, you changed some devices. These changes have improved performance, but they have fatal flaws for the life of this gun."

"Increasing performance will increase the destructive power of recoil, but this is a pistol after all, and it is not a submachine gun. So after being subjected to excessive performance output, it is easy for the bullet to get stuck, or in professional terms, a jam problem!"

“This detail often determines the life of the firearm and the life of the user.”

To be honest, what Chen Jun said made a lot of sense and was very fluent, and everyone could understand it.

However, as a weapons expert, Expert Chen didn't quite understand.

This batch of weapons of his had actually been researched abroad, and he didn't know how many times they had been debugged. It should be impossible for them to have defects such as being damaged by recoil, right?

This has been tested many times.

Of course, Chen Jun is not talking nonsense, he is a master of black technology and a master of firearms. As long as he studies it carefully and relies on his integrated skills, he can immediately find out the defects of the weapons. These are not problems that can be discovered through ordinary tests.

This is a problem that can only be discovered through experience, and often the soldiers who discover this problem will die on the battlefield.

This is also the reason why the improvement of a gun takes decades or even several generations. For the AK47 alone, it took more than years to overcome the problem of preventing sand from jamming.

"That's it..."

Chen Jun began his explanation from the material aspect, talking about the role of mechanics and under what circumstances, qualitative changes will occur... He was like a professor on the podium, giving a passionate speech, and expert Chen and others in the audience, including the rebellious colonel just now, all listened to him quietly, with an expression that said, "You are right, but I don't quite understand."

Finally, Chen Jun finished speaking, and he said confidently: "That's about it. However, Engineer Chen, I think your idea is amazing. The key is that you can actually make it, which is enough to show your level. I dare say that there is no weapon in the world that can switch between different forms so quickly. If you can overcome the defects, you can take off directly."

He still praised it.

"It feels like you haven't said anything, you're just talking nonsense, and in the end, you're just trying to flatter me. Don't you just want the weapons test site to be placed in your base?"

Wang Xun couldn't help but mutter to himself. He didn't dare to say it out loud because he felt that among all the things Chen Jun said, only the last sentence was important.

Generally speaking, the soldiers who come to the Longmai Base are somewhat special. They walk around the five major military regions with great authority and have a very high status. Usually, don’t the chiefs be respectful when they see them?

Chief Engineer Chen told them that it was a small matter as he was the leader after all. However, Wang Xun must be unhappy with Chen Jun's attitude. Anyway, he has never been convinced until now.

"Captain Chen, do you have any way to verify those questions you just mentioned?"

Chief Engineer Chen pondered for a moment and asked the key question.

"The problems you mentioned are indeed very insightful. When I started researching and modeling weapons, I also considered these issues, but I thought they shouldn't be a big problem, so I skipped this step. There were no errors in the subsequent weapon tests. If you can verify it, it would be more straightforward."

Chen Jun glanced at everyone and nodded: "Yes, I do have a way."

Everyone looked at him in shock, wondering what his method was. Was it direct violent destruction? They had tested the shooting test hundreds of times.

"Fire a gun to test it. However, my testing method is different from yours. I will test it in a battlefield mode. Give me the bullet first."

Facing the puzzled faces of the crowd, Chen Jun was like Uncle Da from the Serious Crime Unit 6. He took off his coat, asked for the magazine and bullet bag, and everything was ready.

He wants to use practical actions to show them that details determine success or failure!
