I'm a Super Cop

"I am the murderer?" Looking at Gu Chen, Gao Xiaozhe suddenly has some fluctuations in his heart.

"Officer Gu, I'm a repairman. I don't know the dead at all. If you say I'm a murderer, you have to tell the evidence?"

It may be due to Gu Chen's bad temper. Gao Xiaozhe reacted with some excitement.

Before that, he had been patient and careful, afraid that he could not leave.

But now Gu Chen put the killer's hat on his head.

It seems that the previously suppressed mood for a long time broke out in this moment.

At this time, all the people who were detained on the stage looked at each other and did not know why they looked at them.

In everyone's opinion, Gu Chen's thunder was violent, and he suddenly identified the murderer.

Although some are hasty, some are surprising.

However, when the murder weapon was not found, he dared to identify the murderer. His heart said that the young policeman was too aggressive.

Lu Weiwei asked Gu Chen cautiously: "younger martial brother Gu, do you think he is the murderer? What is the evidence? It depends on the evidence. We haven't found the pistol yet. "

"You don't have to have guns to fire bullets. The 107 rocket launcher, one of the three magic weapons of guerrilla warfare, can also be fired without a gun barrel."

As Gu Chen introduces, he takes Gao Xiaozhe's Toolkit again and puts it on the table.

This time, Gu Chen took out the tools in turn.

Zhao Guozhi hesitated and came to Gu Chen and asked, "Gu Chen, do you think bullets can be fired without guns?"

"Yes." Gu Chen, while placing tools, replied: "it is strictly prohibited for private possession of firearms in our country. Even if we can apply for a gun license, the standard is very strict."

"So I don't think it's very likely that the murderer uses guns to kill people. Otherwise, why can't we find guns when we dig three feet in the bar?"

Zhao Guozhi was asked some embarrassment, quickly explained: "it may be because the murderer hid in a secret corner, or disassembled the gun."

"But even if it's disassembled, we can determine the type of weapon by finding the parts." Gu Chen still replied.

Officer Wang frowned and asked Gu Chen, "Gu Chen, what are your thoughts now?"

"It's very simple. I want to make sure that bullets can still be fired without a gun." Gu Chen put his hands on the table and said with a smile:

"I have studied some interesting experiments, some of which are about guns. However, people who do this kind of lethal experiments usually live abroad."

"So there is a reason why they are small?" She said.

"They will transform ordinary guns into more powerful ones, and they will often do some fantastic things," Gu said

"But when it comes to firearms, naturally, there is no lack of bullets, because the most powerful force of guns is the impact force of bullets. With the extremely powerful launching mechanism, bullets can shoot out thousands of meters away."

"A lot of bullets are ignited by the same mechanism."

"What do you want to say, comrade policeman?" See Gu Chen solution plane principle, the bar manager Wang Haifeng some do not understand Li.

Gu Chen directly added: "what I want to say is that pushing the gun chamber according to the principle is not the only condition for a bullet to be fired."

"As I said just now, the 107 rocket launcher, one of the three major guerrilla Warcraft, can be launched without a barrel, and it can be launched in multiple forms."

Lu Weiwei seemed to understand something, so she asked Gu Chen, "so, is it possible to launch a bullet outside the gun chamber and meet the firing conditions of the bullet?"

Gu Chen slightly nods: "said you may not believe, the answer is OK."

"Yes?" Wang officer Leng Leng Leng, is also light smile said: "this does not need the gun to be able to fire the bullet, I still heard for the first time."

"Therefore, few people in our country will try this kind of experiment, only some people abroad will do it."

"But it's because of this kind of experiment that reminds me of why we can't find guns after the death of brother Howe in the middle of a bullet?"

Seeing Gu Chen looking at himself, Gao Xiaozhe frowned: "but what does this have to do with me? I won't do this kind of experiment."

"Yes, elder martial brother Gu, can we make a mistake?" Yuan Shasha was also the first time to hear that bullets could be fired without guns. She was curious for a moment.

Gu Chen nodded slightly and said: "without the barrel and other structures, bullets will fly without direction, and may even hurt themselves, because such bullets are full of too many uncertain factors, which is also a very dangerous behavior."

"But it's just an objective factor. What I'm going to talk about now is the absolute factor. When a sharp object is used to impact a bullet, the temperature is as high as 3000 degrees Celsius, and the high pressure generated can push the warhead."

"But its power and damage are certainly not as big as those shot from a gun. Therefore, to hurt people, it must be at close range, which can also explain why the dead died in the bathroom, because the space is so large, once hit in the forehead, there is no doubt that he will die."Hearing Gu Chen's words, Zhao Guozhi nodded slightly and raised his own query: "but the combustible temperature of the primer of the bullet is not as simple as imagined. It can only be said that the bullet will be fired when it reaches certain conditions."

"But it's better to use guns to launch bullets. It's illegal to try such dangerous experiments, let alone use bullets to do experiments in which bullets are not fired in guns."

"Zhao Ju, you are right." Gu Chen also agreed with Zhao Guozhi very much, but still put forward his own opinion: "in fact, deliberately knock the bottom of the bullet can be fired."

"In previous wars, there were often cases in which residual ammunition was accidentally touched and detonated on the battlefield."

"Therefore, when a bullet reaches certain conditions and satisfies its firing principle, it can be fired without being placed in the gun chamber."

The manager of the bar, Wang Haifeng, was stunned.

Although Gu Chen said it clearly, Wang Haifeng did not know anything about the principle, so he asked Gu Chen again: "but officer Gu, according to what you said, how did brother Hao's death come about?"

"Have you ever seen a war drama?" Gu Chen asked him.

Wang Haifeng nodded: "of course."

"In the TV series, are bullets fired through guns? Are the bullets in a pistol always in the chamber? "

"Yes Yes, after watching those movements, I feel like I can use a gun Wang Haifeng is also truthful.

"That's right." Gu Chen looked around for a week, his hands and others rowed: "the action before shooting is loading."

"If the bullet can be fixed and hit the bottom of the bullet with other sharp or hard objects, the mercury at the bottom of the bullet is likely to detonate and cause the warhead to launch."

After a pause, Gu Chen said: "of course, this is an extremely dangerous behavior. Let alone the launch of a warhead, it can completely hurt people or objects in front."

"When a bullet is fixed, the stability of the bullet must not meet the requirements of placing it in the barrel. Once the gunpowder in the cartridge case explodes and is affected by the vibration, the fixed bullet will fall off or be dislocated, and the warhead will probably form a fan-shaped injury with a larger angle, and even hurt the shooter himself."

"Therefore, in reality, most of the people who carry out this operation are people who do not know the situation, which is likely to cause personal injury."

The officer took out a cartridge from his pocket and listened to it.

"Senior brother Wang." Gu Chen hooked his hand and said, "borrow your bullet."

"Here you are." Officer Wang handed the bullet to Gu Chen.

"Let's look at the structure of the bullet first." Gu Chen sandwiched the bullet between his fingers, looked around for a week and said:

"it is usually composed of warhead, shell, propellant and primer, and there are two types of bullet firing, namely, bottom edge firing and bottom firing."

"A few bullets use side firing, with the whole bottom of the shell as the detonator, and the bottom is full of propellant. The impact pin directly hits the weak part of the bottom edge of the bullet, and the propellant is squeezed and ignited, thus igniting the propellant."

After looking at Zhao Guozhi's direction, Gu Chen just explained: "the most typical bullet is a 5.6 mm small caliber sports rifle."

"That's right." Zhao Guozhi nodded slightly, confirming Gu Chen's words.

Wang Haifeng looked at the bullet in Gu Chen's hand and said curiously: "in this boy's bullet, the warhead should be the most lethal."

"That's right." Gu Chen nodded with approval and explained: "therefore, whether it is the shell, gunpowder or low-power, the warhead is squeezed out to make it move at a high speed and produce strong lethality."

"With the rapid development of modern technology, however, the technology is becoming more and more mature."

"At the same time, many different launching methods have been produced under the test of some dead people, so the warhead's lethality is also increasing."

"In the process of firing bullets, the most commonly used method is to use primer to complete the firing of bullets."

"I see." Lu Weiwei also grinned when she heard Gu Chen's explanation.

At first, you may not understand, but after Gu Chen's explanation, Lu Weiwei finally understands that Gu Chen's meaning is nothing more than the issue of bullet firing.

After all, an ordinary bullet is basically composed of four parts: warhead, shell, charge and primer.

This basic structure has hardly changed since the second half of the 19th century. This is the basic structure of common bullets.

Moreover, when the trigger is pulled during the firing process, the impact pin will hit the primer at the bottom of the bullet.

When the primer detonates, the internal charge is detonated.

The charge burns and explodes in the narrow bullet, which produces a large amount of gas and ejects the warhead with great kinetic energy to complete the whole firing action.

After learning about these things, Lu Weiwei finally had a score in mind, so she said with a smile: "let's go back to the question just now. Bullets can really be launched by fixed percussion.""But this is really very dangerous, and if the bullet is accidentally dropped, it can cause very serious damage to itself."

"Yes, that's what I want to say." Gu Chen also confirmed Lu Weiwei's words.

At this moment, we all put our eyes back on the maintenance brother Gao Xiaozhe and the tools on the desktop.

"So, you mean These tools can trigger bullets? " Zhao Guozhi picked up an electric drill.

Gu Chen nodded slightly and said calmly, "it turns out that it is very simple."

Speaking of this, Gu Chen put the bullet directly into the rubber management, but it just stuck.

"See?" Gu Chen picked up the rubber tube and showed it to the public: "first, insert the bullet into the rubber tube. This rubber tube is similar to the one used in the gas tank at home, and then we use this one again."

This time, Gu Chen picked up the vice and held the rubber tube in the vice.

"In this way, the caliber of the bullet is made, and the next step is to stimulate the bullet, which requires an electric drill."

"You Are you saying that you can fire the bottom of a bullet with an electric drill? "

Wang Haifeng, the hotel manager, looked at this kind of divine operation, but he couldn't help smacking his tongue in secret. He felt a little subversive.

Gu Chen did not conceal: "in fact, this is a more famous method of launching, which was used in assassination, but now people know less about it. I have seen it by chance."

The voice dropped and the scene was in an uproar.

All the police officers looked at each other.

You may know more about your guns and weapons, but you never pay attention to shooting bullets without guns.

But this time, Gu Chen is to open your eyes and increase your knowledge blind area.

And the many men and women who are isolated above the stage are also astonished.

In everyone's opinion, ordinary maintenance tools can do this.

If Gu Chen didn't say so, we might not have known it for a lifetime.

Gu Chen looked at Gao Xiaozhe, shivering at the moment, and said: "these tools seem ordinary, but in fact, you are very hidden."

"You should be familiar with these methods of operation, so that you can take advantage of your own work to kill people in this way."

Gu Chen said, pressing step by step.

But Gao Xiaozhe is constantly retreating, his face is full of panic.

"You You're talking nonsense. I don't know what you're talking about? I don't know what to shoot without a gun. This This is something that you professionals only know. As a repairman, I don't know what the situation is. You wronged me. "

Gao Xiaozhe spoke with trembling and incoherent words.

But Gu Chen picked up the electric drill directly, pointed to the drill and said, "is it what I said? Take this tool to test and know."

"When the electric drill fired the primer, it would leave traces. I had been wondering why there was a smell of gunpowder on the drill bit."

"At first, I thought it might have been left by the drill bit when drilling into the wall, but if you identify it carefully, it's just the smell of gunpowder carried by the bullet."

"You You can smell it all? " Gao Xiaozhe doesn't know when, the sweat on his forehead is flowing down unconsciously.

Gu Chen nodded slightly and said, "I don't know, and you just left empty handed, which made me doubt."

"A professional maintenance personnel who relies on tools to earn money even left the scene without tools. Maybe I can understand it as nervous."

"But when I saw the tools in your kit, I was suspicious for the second time, because the leather tubes looked more like gun barrels."

"And in one of the tubes, I smelled a familiar smell."

Seeing Gao Xiaozhe's face blue, Gu Chen bowed forward and said, "yes, it's the smell of gunpowder."

"PATA!" When Gao Xiaozhe retreated, his feet staggered and hit a small table directly.

He quickly held the table to keep himself stable.

At the moment, he was forced to a corner by Gu Chen and could not retreat.

Gu Chen handed the drill to Lu Weiwei and said, "you are very smart. You have done something that no one has ever done. I just want to know, where did your bullet come from?"

"I..."

"You don't have to argue any more." Seeing Gao Xiaozhe hesitating and thinking, Gu Chen directly interrupts: "because this is the case, we can take the tools back to the testing room to test all the residual items, and we can always find traces of bullets and gunpowder."

"So You are the killer. "

"Wow..."

Gu Chen's voice dropped, and the scene was in an uproar again.

We worked together to search the weapon for a long time. This weapon is a tool for maintenance.

This made many old colleagues present astonished and felt that the future was daunting, but it was really not a word or two that could be said clearly.Zhao Guozhi also nodded slightly.

At first, I was still worried about the lost guns.

Zhao Guozhi also knows that if we can't find guns tonight, it will have very serious consequences.

But now Gu Chen, through his own judgment and reasoning, has successfully found the principle of bullet firing.

In this way, the scene can explain how the bullet went into the dead man's head.

Gao Xiaozhe some despair, hands covered his cheek, some regret: "just a little, just a little less, I can go out of this place."

He raised his head and looked at Gu Chen and said with hatred: "but why do you want to expose me?"

"Give me a few more seconds, just a few seconds, and I'll be able to get out of this place, and I'll disappear. You police will never find me."

"But why? Why did you stop me? "

Gao Xiaozhe's tears flowed.

I thought I could walk out of the bar a few more steps.

But now Gu Chen stops himself and restores the process of his murder of brother Hao.

And according to their own tools, the successful discovery of bullet powder residues.

With these evidences, even if Gao Xiaozhe had 10000 reasons to get rid of the crime, he was still doomed in the end.

Originally thought of the perfect escape technique, even kowtow to show weakness, in order to win the sympathy of Furong Branch Director Zhao Guozhi.

But all this seems to be late.

He has done so much bedding, and even Wang Haifeng, the bar manager in lalamont, confirms his identity.

I thought things could go on as planned.

However, Gu Chen's appearance is tantamount to stamping out his last hope.
