"Am I the murderer?" Gao Xiaozhe looked at Gu Chen, his heart suddenly fluctuated.
"Officer Gu, I am a maintenance worker and I don't know the deceased at all. If you say that I am the murderer, then you have to provide evidence, right?"
Perhaps because he was angry with Gu Chen, Gao Xiaozhe reacted a little excitedly.
Before this, he had been holding back and being careful at all times, fearing that he would not be able to escape.
But now Gu Chen puts the hat of murderer on his head.
It seemed that the emotions that had been suppressed for a long time broke out at this moment.
At this time, all the detained people on the stage looked at each other and looked at the two people in confusion.
In everyone's opinion, Gu Chen was like a thunderstorm, and he suddenly identified the murderer without making a sound.
Although some are rushed, some are surprising.
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, where is the evidence? You have to talk about evidence. We haven't found the pistol yet."
"Firearms are not necessarily required to fire bullets. The 107 rocket launcher, one of the three greatest weapons of guerrilla warfare, can also be fired without a barrel."
As Gu Chen introduced it, he took the tool bag from Gao Xiaozhe's hand again and placed it on the table.
This time, Gu Chen took out the tools inside again.
Zhao Guozhi was a little hesitant and came over to ask Gu Chen: "Gu Chen, you said bullets can be fired without firearms?"
"Yes." Gu Chen replied while placing the tools: "Private ownership of firearms is strictly prohibited in our country. Even if you can apply for a gun license, the standards are very strict."
"So I think the possibility of the murderer using a firearm to kill is very low. Otherwise, why would so many of us dig three feet under the bar and still not be able to find a firearm?"
Zhao Guozhi was a little embarrassed when asked, and quickly explained: "It may be because the murderer is hiding in a secret corner somewhere, or the gun is dismantled."
"But even if it is dismantled, we can still determine the type of weapon by finding its parts." 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 the bullets without using a gun." Gu Chen put his hands on the table and said with a faint smile:
"I have studied some interesting experiments, some of which were about firearms. However, people who do this kind of death-defying experiments usually live abroad."
"So there is 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, firearm bullets are naturally indispensable, because the most powerful thing about firearms is the impact of the bullet. With the extremely powerful launching mechanism, the bullet can reach thousands of meters away."
"There are many types of bullets, but their principles are the same. They all rely on stimulation such as mechanical energy to ignite the propellant and launch the bullet."
"Comrade police, what do you want to say?" Seeing Gu Chen explain the reason, the bar manager Wang Haifeng 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 firing bullets."
"As I just said, the 107 rocket launcher, one of the three major guerrilla warfare artifacts, can also be fired 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 fire the bullet when it is outside the barrel and meets the firing conditions of the bullet?"
Gu Chen nodded slightly: "You may not believe it, but the answer is yes."
"Okay?" Officer Wang was stunned and said with a slight smile: "You can fire bullets without a gun. This is the first time I've heard of it."
"So, few people in our country will try this kind of experiment, 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 why we couldn't find the firearm after the deceased Brother Hao was shot to death?"
Seeing Gu Chen looking at him, 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."
"Yes, Senior Brother Gu, could it be that we made a mistake?" Yuan Shasha was also the first to hear that bullets could be fired without firearms, and she was curious for a moment.
Gu Chen nodded slightly and said: "Without the barrel and other structures, the bullets will fly around without direction, and may even hurt yourself, because this kind of bullet is full of too many uncertain factors, and it 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 the bullet, the temperature is as high as 3,000 degrees Celsius, and the high pressure generated can push the warhead."
"But its power and damage will definitely not be as great as those fired from a gun. Therefore, to hurt people, it must be at close range. This can also explain why the deceased died in the bathroom, because the space is so big, once hit
The forehead will definitely die."
After hearing what Gu Chen said, Zhao Guozhi nodded slightly and raised his own doubts: "But the flammable temperature of the bullet's primer is not as simple as imagined. It can only be said that the bullet will be fired when it reaches certain conditions."
"But it is better to use a firearm to fire bullets. It is illegal to try such a dangerous experiment, let alone use bullets to do experiments where the bullets are not fired from the gun."
"Director Zhao, you are right." Gu Chen also agreed with Zhao Guozhi's opinion, but still put forward his own opinion: "In fact, you can launch the bullet by deliberately tapping the bottom of it."
"In previous wars, there were often cases where leftover ammunition was accidentally detonated on the battlefield."
"So when the bullet reaches certain conditions and satisfies its firing principle, the bullet can be fired without being placed in the chamber."
Bar manager Wang Haifeng was stunned for a moment after hearing this.
Although what Gu Chen said was very clear, Wang Haifeng still didn't understand the principles, so he asked Gu Chen again: "But Officer Gu, according to what you said, what caused Brother Hao's death?"
"Have you ever watched any war-themed TV series?" Gu Chen asked him.
Wang Haifeng nodded: "Of course."
"In TV dramas, are bullets fired from firearms? Are the bullets in pistols usually kept in the chamber?"
"Yes... yes, after watching those actions, I feel like I can use a gun." Wang Haifeng 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 you can fix the bullet and hit the bottom of the bullet with other sharp or hard objects, it is entirely possible that the mercury fulminate at the bottom of the bullet will detonate, causing the warhead to be launched."
After a pause, Gu Chen continued: "Of course, this is an extremely dangerous behavior. Let alone launching warheads, it can completely harm people or objects in front of you."
"When fixing the bullet, the stability of the bullet will definitely not meet the requirements of being placed in the barrel. Once the gunpowder in the cartridge case explodes and is affected by vibration, the fixed bullet will fall off or be misplaced, and the bullet will likely form a larger angle.
fan-shaped damage, and even hurt the launch personnel themselves."
"So in reality, the vast majority of people who perform this operation are people who do not understand the situation, and the consequences are likely to be personal injury."
After hearing what Gu Chen said, Officer Wang quickly took out his gun, unloaded the magazine, took out a bullet and held it in his hand for observation.
"Senior Brother Wang." Gu Chen raised his hand to him and said, "I'll lend you your bullet."
"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 two fingers, looked around and said:
"It usually consists of a warhead, a cartridge case, propellant and a primer, and there are two types of bullet launches, namely bottom rim launch and bottom launch."
"A few bullets are rim-fired, using the entire bottom of the bullet case as the detonator. The bottom is filled with propellant. The firing pin directly hits the weak part of the bottom of the bullet, and the propellant is squeezed and ignited, thereby igniting the propellant."
Looking in the direction of Zhao Guozhi, Gu Chen also explained: "The most typical bullet is the 5.6mm small-caliber sports rifle."
Wang Haifeng looked at the bullet in Gu Chen's hand and said curiously: "Among these small bullets, the warhead should be the most deadly."
"That's right." Gu Chen nodded in agreement and explained: "So whether it is a cartridge case, gunpowder or anything else, it squeezes out the warhead and makes it move at high speed, producing powerful lethality."
"But with the rapid development of modern science and technology, bullet firing technology is becoming more and more mature."
"At the same time, many different launch methods have been produced through the experiments of some people seeking death, so the lethality of the warheads has also become greater and greater."
"In the process of firing bullets, the most common method is to use a primer to complete the firing of the bullet."
"I understand." Lu Weiwei also grinned after hearing Gu Chen's explanation.
She might not understand it at first, but after Gu Chen explained it carefully, 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, the cartridge case, the charge and the 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 small bullet, producing a large amount of gas, which ejects the warhead with great kinetic energy, completing the entire firing action.
After understanding these things, Lu Weiwei finally had some idea in her mind, so she smiled lightly and said: "Let's go back to the problem just now. Bullets can really be fired with fixed knocks."
"But this is really, really dangerous, and if the bullet is accidentally dropped, it may cause serious injury to yourself."
"Yes, that's what I want to say." Gu Chen also confirmed Lu Weiwei's words.
At this moment, everyone turned their attention back to the maintenance man Gao Xiaozhe and the tools on the table.
"So, what you, Gu Chen, mean...are these tools capable of causing bullet excitation?" Zhao Guozhi picked up an electric drill and asked.
Gu Chen nodded slightly and said calmly: "The principle is actually very simple."
Having said this, Gu Chen directly stuffed the bullet into the rubber tube, just enough to get it stuck.
"Did you see that?" 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 gas tanks at home. Then we will use this..."
This time, the tool Gu Chen picked up was a vise, and clamped the rubber tube with the vise.
"In this way, the bullet's firing caliber is produced, and the next step is to activate the bullet, which requires an electric drill."
"You...you mean, you can use an electric drill to stimulate the bottom of the bullet and it can be fired?"
Hotel manager Wang Haifeng couldn't help but secretly smacked his tongue when he saw this magical operation, feeling that it was a bit subversive.
Gu Chen did not hide it and said: "Actually, this is a relatively famous launch method. It was once used in assassinations. It's just that few people know about it now. I also saw it by chance."
As soon as the words fell, the scene was in an uproar.
All the police officers looked at each other.
You may be familiar with your own firearms, but you have never paid attention to firing bullets without a gun.
But this time, Gu Chen opened everyone's eyes and increased everyone's knowledge blind spots.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! And many men and women who were isolated above the stage were also shocked at this moment.
In everyone's opinion, ordinary maintenance tools can actually do this.
If Gu Chen hadn't said this, everyone might not have known it all their lives.
Gu Chen glanced at Gao Xiaozhe, who was trembling at the moment, and said: "These tools may seem ordinary, but in fact you hide them very deeply."
"You should be familiar with these operating methods, so you took advantage of the convenience of your job and adopted this method to kill people."
Gu Chen said as he pressed forward step by step.
Gao Xiaozhe, on the other hand, kept retreating, with a look of horror on his face.
"You...you are talking nonsense. I have no idea what you are talking about? I don't know anything about gunless shooting. This...this is something that only you professionals know. I am a maintenance worker and I don't know anything at all."
In this case, you have wronged me."
Gao Xiaozhe spoke tremblingly and somewhat incoherently.
But Gu Chen directly picked up the electric drill, pointed at the drill bit and said, "Is this what I said? Just take this tool for testing and you will know."
"The electric drill fires the primer of the bullet and leaves traces. I used to wonder why there was a gunpowder smell on the drill."
"At first I thought it might be left behind when the drill bit drilled into the wall, but after careful inspection, 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 the sweat on his forehead started to flow down unconsciously.
Gu Chen nodded slightly and said, "It's not that I know, and you just left empty-handed in a hurry, which made me suspicious."
"A professional maintenance man who makes a living from tools actually left the scene without even taking his tools with him. Maybe I can understand that he was nervous."
"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 inside one of the leather tubes, I smelled a familiar smell."
Seeing Gao Xiaozhe's face turned blue, Gu Chen bowed forward and said, "Yes, it smells like gunpowder."
"Bah!" Gao Xiaozhe staggered while retreating, and hit a small table directly.
He quickly held on to the small table to keep himself steady.
At this moment, he was forced into a corner by Gu Chen and had no way to retreat.
Gu Chen handed the electric drill to Lu Weiwei and said, "You are very smart. You have done something that no one has done before. I just want to know where your bullets came from?"
"I……"
"You don't have to quibble anymore." Seeing Gao Xiaozhe hesitating and thinking, Gu Chen interrupted directly: "Because that's the fact. We can take the tools back to the inspection 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.
Everyone worked hard to search for weapons for a long time. Is this weapon a maintenance tool?
This shocked many of the old colleagues present. They felt that the fear of future generations cannot be explained clearly in just one or two sentences.
Zhao Guozhi also nodded slightly.
At first, I was still worried about the missing firearms.
Zhao Guozhi also knew that if no firearms were found tonight, it would have very serious consequences.
But now, through his own judgment and reasoning, Gu Chen successfully found the principle of firing bullets.
In this way, how the bullet entered the head of the deceased Brother Hao can be explained at the scene.
Gao Xiaozhe was a little desperate, covering his cheeks with his hands, feeling regretful: "Just a little bit, just a little bit close, 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 leave this hellish place. I can just disappear. You policemen will never find me."
"But why? Why did you stop me?"
Gao Xiaozhe's tears were streaming down his face.
I originally thought that if I took a few more steps, I would be able to walk out of the bar.
But now Gu Chen stopped himself and reconstructed the process of murdering Brother Hao exactly.
And according to his own tools, he successfully found the remains of bullets and gunpowder.
Based on this evidence, even if Gao Xiaozhe had 10,000 reasons to escape guilt, he would still be doomed in the end.
Originally thinking of perfect escape techniques, he even kowtowed to show weakness in order to win the sympathy of Furong Branch Chief Zhao Guozhi.
But all this seems to be too late.
He had done so much preparation, and even invited the bar manager Wang Haifeng, who was kept in the dark, to confirm his identity.
I originally thought that things would develop as I planned.
But the appearance of Gu Chen was tantamount to stamping out his last hope.
