    After the meeting, we dragged our tired bodies back to our respective offices and took a nap. When we opened our eyes again, it was already past eight in the morning.  Brother Ming carried a green instrument and knocked on the doors one by one.

    I heard the noise, twisted my neck, and tried my best to rub my sleepy eyes with my right hand. A ray of sunlight shined on my desktop through the crack in the door. When I woke up, Ye Qian had already finished washing and was standing in front of me.

    ¡°Let¡¯s go quickly, Director Leng and the others are ready, waiting for you to find the shooting spot!¡± Ye Qian said to me while applying some hand cream.

    ¡°Oh!¡± I got up a little tiredly and walked out of the corridor.

    ¡°Xiaolong, is this okay?¡± Brother Ming placed a metal instrument shaped a bit like a bent lollipop in front of me and asked.

    "Okay." I nodded.

    "Okay, I'll start the car, and you hurry up." Brother Ming put the instrument in my hand, turned around and left.

    Ye Qian walked up to me at this time, poked her head in, took the instrument from my hand curiously and asked, "What is this?"

    "Isn't there something written behind the butt?" I answered with a yawn.

    Ye Qian glanced at the Chinese characters on the handle of the instrument and read out: "Metal detector."

    "What do you use this for?"

    "Looking for bullet casings!" I rubbed my cheeks with my hands to cheer up and replied.

    "Why are you looking for bullet casings?" Ye Qian still refused.

    When I heard this, I simply took out a cigarette from my pocket and lit it, then leaned against the corridor window and replied: "When the gun is fired, the bullet is ejected, and the shell will be ejected from the barrel.  Do you understand?"

    "This is common sense, of course I know it."

    I blew out a puff of smoke and said, "But there's one thing you definitely don't know."

    "What?" Ye Qian frowned.

    "It's the traces of bullets from gunfire."

    "You tell people off every day, can you make it clearer?" Ye Qian said, raising her fist to demonstrate to me.

    When I saw her move, I stepped aside and said, "Calm down, I'm going to say it now. If we want to know the traces of the bullet, we must first talk about the entire process of firing the bullet and the structure of the bullet."

    "To put it simply, a general bullet is composed of three parts, the warhead, the cartridge case, and the primer. The principle of firing is that the firing pin in the pistol detonates the primer in the cartridge case, and then under the huge impact, the warhead is  was fired and the shell casings were ejected."

    "Tell me the important point!" Ye Qian anxiously slapped her hand on the window frame next to me.

    "Can you stop being impatient?" I took another step back.

    Ye Qian put away her right hand, inserted it into her pocket, looked at me very unfriendly, and said in a sinister way: "What do you think?"

    Upon seeing this, I quickly replied: "Now that we know the principle of bullet firing, we also need to know what traces will be produced during the entire firing process of the bullet. The first step before shooting is to put the bullet into the magazine and pull it into the gun chamber.  During the loading process, the bullet will collide with the gun, and reloading marks will appear."

    "The second step is that when the bullet is fired, the firing pin hits the bottom of the bullet, and there will be marks of the firing pin. The bullet rotates at high speed in the spiral barrel, and there will be marks of the barrel. The bullet case touches the bottom of the bullet when it is thrown.  There will also be marks on the outside of the gun. Although these marks are inconspicuous, they can identify the gun!"

    "What? Use these traces to identify guns?" Ye Qian said incredulously.

    I put out my cigarette and nodded: "Although guns are batch-processed by machine tools, in fact no two guns can be made exactly the same. In addition, people's usage habits are different, so every gun has different shooting processes.  , the marks left on the bullet heads and bullet cases are different. But if the bullets are fired from the same gun, then the marks are regular. Take the May 4th pistol you shot yesterday, for example.  When you fire a bullet, as long as you find the traces on the cartridge case and the bullet after you fired it, I can judge through a simple experiment whether the bullet was fired from your gun. Now you understand.  ?¡±

    "Oh! So you use a metal detector to find the bullet casing fired by the suspect at the shooting point, and then use the marks on the bullet and bullet casing to determine the gun used by the suspect. Guns are a tool for committing crimes, and the suspect must  Don't dare to throw it away. In other words, we only need to find a gun next to someone, and then you do an inspection. If it can be confirmed that the bullet was fired by his gun, then we can basically identify the suspect.What are the abnormalities?  "

    I looked carefully in the direction of his finger and shook my head.

    "Didn't you notice that there are three square depressions here?" Fat Lei reminded again.

    "Really, here." Ye Qian smoothed her hair on her temples and said with squinted eyes.

    Fat Lei patted the dirt on his hands, sat on the ground and explained to us: "I just thought of a detail. The crime occurred at night. Although there were not many vehicles on the road, it is impossible to tell the difference with the naked eye.  Which car belongs to the deceased. So I guess the suspect must have observed the license plate number and judged the target of the crime from this point."

    "That's for sure. All the cars look the same tonight. How can we do it without looking at the license plate?" I thought Fat Lei had some great ideas. After hearing him say such unworthy words, I immediately retorted.

    After hearing this, Fat Lei rolled his eyes at me and said, "We drive at night with our headlights on. How can people see the license plate clearly in the backlight? Do you think you are clairvoyant?"

    "This" I was dumbfounded when I heard what he said.  (Remember the website address: www.hlnovel.com
