I am a super cop

Chapter 952 The fire of hope was crushed by Gu Chen
"I'm the murderer?" Gao Xiaozhe looked at Gu Chen, his heart fluctuated suddenly.

"Officer Gu, I'm a maintenance worker and I don't know the deceased at all. If you say I'm the murderer, then you have to give evidence, right?"

Probably because of being offended by Gu Chen, Gao Xiaozhe reacted a little excitedly.

Before this, he had been forbearing and careful everywhere, fearing that he would not be able to get away.

But now Gu Chen puts the murderer's hat on his head.

It seemed that the mood that had been suppressed for a long time broke out at this moment.

At this time, all the detained persons on the stage looked at each other, looking at the two for some unknown reason.

From everyone's point of view, Gu Chen was a thunderstorm, he suddenly recognized the murderer without making a sound.

Although a little hasty, some are eye-popping.

However, when the murder weapon was not found, he dared to identify the murderer, thinking that this young policeman was too impulsive.

Lu Weiwei asked Gu Chen cautiously: "Junior Brother Gu, you said he was the murderer, what evidence? It's about evidence, we haven't found the pistol yet."

"Firing bullets does not necessarily require firearms. The 107 rocket launcher, one of the three great weapons of guerrilla warfare, can also be fired without a barrel."

While introducing, Gu Chen took the tool bag from Gao Xiaozhe's hand again and put it on the table.

This time, Gu Chen took out the tools inside one by one again.

Zhao Guozhi was a little hesitant, and came over to Gu Chen and asked, "Gu Chen, you said bullets can be fired without guns?"

"Yes." Gu Chen replied while placing the tools: "In our country, private ownership of firearms is strictly prohibited. Even if you can apply for a gun license, the standards are very strict."

"So I think the possibility of the murderer using a gun to kill people is very low. Otherwise, why do so many of us dig three feet in the bar and can't find a gun?"

Zhao Guozhi was a little embarrassed when asked, and quickly explained: "It may be because the murderer hid in a hidden corner somewhere, or disassembled the gun."

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

Officer Wang frowned and asked Gu Chen, "Gu Chen, what are you thinking now?"

"It's very simple. I want to make sure that I can still shoot bullets without using 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 firearms, but those who do this kind of deadly experiment generally live abroad."

"So there's a reason for their small population?" Lu Weiwei said.

Gu Chen said: "They will transform ordinary firearms into more powerful firearms, and they often do some incredible things."

"But when it comes to firearms, the bullets of firearms are naturally indispensable, because the most powerful thing about firearms is the impact force of the bullets. With the extremely powerful firing mechanism, the bullets can reach kilometers away."

"There are many types of bullets, but their principles are the same, they are all triggered by mechanical energy and other stimuli, and ignite the propellant to fire the bullet."

"Comrade policeman, what do you want to say?" Seeing Gu Chen's explanation, Wang Haifeng, the bar manager, was a little confused.

Gu Chen said directly: "What I want to say is that pushing the barrel of the gun according to the principle is not the only condition for the bullet to be fired."

"As I said just now, the 107 rocket launcher, one of the three major guerrilla warfare artifacts, can also 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 outside the barrel of the gun, and the bullet can be fired if the firing conditions are met?"

Gu Chen nodded slightly: "I told you that you might not believe it, but the answer is yes."

"Yes?" Officer Wang was stunned for a moment, and then said with a smile, "This is the first time I've heard that bullets can be fired without a gun."

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

"But it is precisely because of the existence of this kind of experiment that it reminds me of the deceased brother Hao who was shot and killed. Why can't we find guns?"

Seeing Gu Chen looking at him, the maintenance brother Gao Xiaozhe frowned: "But what does this have to do with me, I don't know how to do this kind of experiment."

"That's right, Senior Brother Gu, could it be that we made a mistake?" Yuan Shasha was also curious for a while when she heard that bullets could be fired without guns.

Gu Chen nodded slightly, and said: "Without the barrel and other structures, the bullets will fly randomly without direction, and may even hurt yourself, because this kind of bullet is full of too many uncertain factors, which is also a very dangerous weapon. Behavior."

"But this is only an objective factor. What I want to talk about now is an absolute factor, that is, 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 bullet."

"However, its power and damage will definitely not be as great as those fired from a gun. Therefore, if you want to hurt someone, you must be at a close range. This can also explain why the deceased will die in the bathroom, because the space is so large. Once hit Forehead, there is no doubt that you will die."

Hearing Gu Chen's remarks, Zhao Guozhi nodded slightly and raised his own doubts: "But the flammable 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 meets certain conditions."

"But it is better to use firearms to fire bullets. It is illegal to try such a dangerous experiment, let alone use bullets to do experiments that do not fire bullets in guns."

"Zhao Ju, you are right." Gu Chen also agreed with Zhao Guozhi's opinion, but still put forward his own opinion: "Actually, you can launch the bullet by deliberately hitting the bottom of the bullet."

"In past wars, there were often cases of remaining ammunition on the battlefield being detonated by mistake."

"So when the bullet reaches certain conditions and satisfies its firing principle, the bullet can be fired without being placed in the barrel."

Wang Haifeng, the bar manager, was taken aback when he heard this.

Although what Gu Chen said was very clear, Wang Haifeng still didn't know anything about the principle, so he asked Gu Chen again: "But Police Officer Gu, according to what you said, how did Brother Hao's death happen?"

"Have you watched war dramas?" Gu Chen asked him.

Wang Haifeng nodded: "Of course."

"In TV dramas, are the bullets fired from firearms? Are the bullets in pistols usually placed in the chamber?"

"Yes... yes, after seeing those actions, I feel that I can use a gun." Wang Haifeng also said truthfully.

"That's right." Gu Chen looked around and gestured with everyone with his hands: "The action before shooting is to load the gun."

"If the bullet can be fixed and hit the bottom of the bullet with other sharp or hard objects, it is entirely possible that the thunderbolt at the bottom of the bullet will detonate, causing the warhead to be fired."

After a pause, Gu Chen said again: "Of course, this is an extremely dangerous behavior. Leaving aside the firing of bullets, it can completely harm people or objects in front of you."

"When the bullet is fixed, the stability of the bullet will definitely not meet the requirements of being placed in the barrel. Once the gunpowder in the shell explodes, affected by the vibration, the fixed bullet will fall off or be misplaced, and the bullet will likely form a larger angle. sector, and even hurt the launch personnel themselves."

"So in reality, most of the people who carry out this operation are people who don't understand the situation, and the result is likely to be personal injury."

Hearing what Gu Chen said, Officer Wang hurriedly took out his own gun, removed the magazine, took out a bullet from it, and held it in his hand to observe.

"Senior Brother Wang." Gu Chen hooked his hands at him and said, "I'll borrow your bullets."

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

"Let's take a look at the structure of the bullet first." Gu Chen held the bullet between his fingers, looked around for a week, and said:
"It usually consists of a bullet, casing, propellant and primer, and there are also two types of bullet firing, bottom edge firing and bottom firing."

"A small number of bullets are edge-fired. The entire bottom of the bullet case is used as the detonator. The bottom is filled with propellant. The firing pin directly hits the weak part of the bottom of the bullet. The propellant is squeezed and ignited, thereby igniting the propellant."

Glancing in Zhao Guozhi's direction, Gu Chen also explained: "And the most typical bullet is a 5.6mm 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: "Then among this small bullet, the bullet should be the deadliest."

"That's right." Gu Chen nodded in agreement, and explained: "So whether it's the shell casing, gunpowder or others, the bullet is squeezed out to make it move at a high speed and produce powerful lethality."

"But with the rapid development of modern science and technology, bullet launch technology is becoming more and more mature."

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

"In the process of firing bullets, the most common method is to use a primer to complete the firing of the bullet."

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

At first, it might not be clear, but after Gu Chen's careful explanation, Lu Weiwei finally understood that what Gu Chen wanted to express was nothing more than the issue of bullet firing.

After all, an ordinary bullet is basically composed of four parts, namely the warhead, shell case, 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, during the firing process of the bullet, when the trigger is pulled, the firing pin will hit the primer part at the bottom of the bullet.

The moment the primer detonates, the internal charge is detonated.

The charge burns and explodes inside the narrow bullet, producing a large amount of gas, and ejects the warhead with great kinetic energy to complete the entire firing action.

Knowing these things, Lu Weiwei finally had a clue in her heart, so she said with a light smile: "Let's go back to the question just now, bullets can really be fired with fixed tapping."

"But it's really very, very dangerous, and if the bullet falls inadvertently, it can cause very serious injury to yourself."

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

At this moment, everyone turned their attention to Gao Xiaozhe, the maintenance brother, and the tools on the table.

"So, you, Gu Chen, mean...these tools can cause bullet excitation?" Zhao Guozhi picked up an electric drill and said.

Gu Chen nodded slightly, and said calmly: "The principle is actually very simple."

Having said that, Gu Chen directly stuffed the bullet into the rubber tube, just enough to get stuck.

"Did you see it?" Gu Chen picked up the rubber tube and showed it to everyone: "First put the bullet into the rubber tube, this kind of rubber tube is similar to the one used on the gas tank at home, and then we will use this..."

This time, the tool Gu Chen picked up was a vise, and the vise was used to clamp the rubber tube.

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

"You...you mean, you can fire the bullet by stimulating the bottom of the bullet with an electric drill?"

Wang Haifeng, the hotel manager, looked at this kind of magical operation, and couldn't help clicking his tongue secretly, feeling a bit subversive.

Gu Chen didn't hide it: "Actually, this is a relatively well-known launch method, which was used in assassination operations, but now people know less about it. I also saw it by chance."

The voice fell, and the scene was in an uproar.

All the police officers looked at each other in blank dismay.

You may know your own firearms and weapons better, but you have never paid attention to firing bullets without a gun.

But this time, Gu Chen opened everyone's horizons and increased their knowledge blind spots.

And the many men and women who were isolated above the stage were also shocked at this moment.

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

If it weren't for Gu Chen's words, everyone might not have known it in their entire lives.

Gu Chen glanced at Gao Xiaozhe who was trembling at the moment, and said, "These tools seem ordinary, but you are actually hiding them very deeply."

"You should be familiar with these methods of operation, so you use the convenience of your own work to use this method to kill people."

While talking, Gu Chen pressed forward step by step.

But Gao Xiaozhe kept backing away, his face full of horror.

"You... you're talking nonsense, I don't know what you're talking about at all? I don't even know what gunless shooting is. This... This is something only you professionals know. I'm a maintenance worker and I don't know anything at all. The situation, you wronged me."

Gao Xiaozhe spoke tremblingly, and was somewhat incoherent.

But Gu Chen directly picked up the electric drill, pointed at the drill bit and said, "Is it what I said, just take this tool for testing and you will know."

"The electric drill fires the primer and leaves traces. I wondered why there was a smell of gunpowder on the drill bit."

"At first, I thought it might be left behind when the drill bit drilled into the wall, but after careful identification, I found that it was completely the smell of gunpowder that came with the bullet."

"You...you can smell this?" Gao Xiaozhe didn't know when, beads of sweat dripped down his forehead unconsciously.

Gu Chen nodded slightly, and said, "It's not that I know, and you left in a hurry with empty hands just now, which made me suspicious."

"A professional maintenance man who earns his living by tools doesn't even bring tools with him when he leaves the site. Maybe I can understand it as nervousness."

"But when I saw the various tools in your tool bag, I became suspicious for the second time, because those leather tubes looked more like gun barrels."

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

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

"Pa-ta!" Gao Xiaozhe staggered with both feet while backing away, and directly bumped into a small table.

He quickly supported the small table to keep himself stable.

At this moment, he was forced into a corner by Gu Chen, and there was no way he could retreat.

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

"I……"

"You don't need to make excuses anymore." Seeing Gao Xiaozhe was hesitating and thinking, Gu Chen interrupted directly: "Because that's the truth, we can bring the tools back to the testing room and test all the remaining items, and we can always find bullets and gunpowder. Mark of."

"So...the murderer is you."

"Wow..."

After Gu Chen finished speaking, the scene was once again in an uproar.

The co-authors worked hard to search for weapons for a long time. Is this weapon a tool for repairs?
This stunned many old colleagues present, feeling that the younger generation is awesome, but it really can't be explained clearly in one or two sentences.

Zhao Guozhi also nodded slightly.

At first, I was still worrying about the missing firearms.

Zhao Guozhi also knew that if no firearms were found tonight, there would be very serious consequences.

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

In this way, how the bullet entered the head of the deceased brother Hao can be explained on the spot.

Gao Xiaozhe was a little desperate, covered his cheeks with his hands, and regretted: "Just a little bit, just a little bit, I can get out of this place."

He looked up at Gu Chen, and said with hatred: "But why did you expose me?"

"Give me a few more seconds, just a few seconds, and I can get out of this damn place, I can just disappear, and you police will never find me."

"But why? Why did you call me?"

Gao Xiaozhe burst into tears.

Originally, he thought that if he walked a few more steps, he would be able to walk out of the bar.

But now Gu Chen stopped himself, and restored the process of murdering Brother Hao in detail.

And according to their own tools, they successfully found the remains of gunpowder in the bullets.

Based on these evidences, even if Gao Xiaozhe had 1 reasons to escape the crime, he was still doomed in the end.

Originally thinking of a perfect escape technique, he even kowtowed to show weakness in order to win the sympathy of Zhao Guozhi, the director of Furong Branch.

But all of this seems to be too late.

After doing so much foreshadowing, he even invited the bar manager Wang Haifeng, who was kept in the dark, to confirm his identity.

I thought things would go as planned.

However, the appearance of Gu Chen is equivalent to stamping out his last flame of hope.
