There was a hole in the wall of the crime scene that was very similar to the one found in the hospital bathroom.

In the bathroom of the hospital, Yan Huijiao's body was nailed, and what nailed the corpse was the one in the Killing Angel, the female killer used the steel arrow shot by the strange machine.

There are similar potholes in the current wall, plus the punctures I found in the elevator. Then it is easy to judge that here, a female killer may have appeared. To be exact, the strange weapon she used was there.

However, the situation at the scene is still very strange. Because judging from the location of the potholes in the wall, the steel arrow was fired from the position of the window.

Here, I have two judgments. The first is the female killer standing in a window position and firing a steel arrow at the wall. If so, then the killer and the three deceased should have known each other, and it was the steel arrow that was fired after entering the room.

But the cause of death of these people at the scene was not caused by steel arrows, but VX nerve agent. So this is not very logical, why would a female killer stand in the house and fire a steel arrow for no reason? Could it be that she was testing the power of her weapon? This consideration is obviously a bit too far-fetched.

Then the second possibility arises. The steel arrows are fired into the room from the window, and they carry a special vessel filled with VX nerve agent.

But this inference leads to a strange situation, because outside the window is a wilderness, and no high-rise buildings exist parallel to the house of the 16th-story house. Then the steel arrow was obviously shot into the house in mid-air.

I went to the window and opened it, and the window opened in a straight line with the hole in the wall. This confirmed that the steel arrows were indeed fired into the house from a location outside the window.

But how did the female killer do it?

Of course, everyone can think of some special effects. For example, pulling a rope to swing in the air and then firing a steel arrow. Or, like a spider, hang a rope upside down with a golden hook and drop it down to the window and fire steel arrows. Even use unmanned small aerial vehicles to hang weapons and equipment to attack this house.

However, I don't want to delve into the specific method used, because it has little to do with solving the case, only that this magical female killer successfully shot the steel arrow with the gas bomb into the room.

Of course, if I had to say so, I would think it was the female killer who used a climbing rope to land on the window edge at great speed, and crouched on the window edge to fire steel arrows with gas bombs.

As for why I judged this way, it was because I found that the aluminum alloy window edge was a little curl. This kind of curl is difficult to do in ordinary trampling situations, and this kind of stampede is obviously very powerful, which is formed by falling from a high place and stepping vigorously.

Of course, landing accurately from above and stepping on the edge of a window sunken in the wall is not something that ordinary people can do.

Once the source of the VX nerve gas bomb was determined, I looked at the scene for other possible residual evidence. Like the gas bombs and steel arrows.

However, after questioning the investigators at the scene, no remnants of steel arrows and gas bombs were found at the scene.

Then it can be determined that the remnants of steel arrows and gas bombs were taken away by the killers.

But why is that? Why take away the remnants of steel arrows and gas bombs?

So I thought of a possibility, that is, the female killer had disconnected from the Qu Mo crime group and drew a clear line. Because of this, the equipment of the female killer will be reduced after use, and there is no way to replenish it. That's why she recycles her equipment.

Recovering steel arrows, this is obviously very obvious. But what about recovering the remnants of the VX nerve gas bomb?

I pondered for a moment, looked at the hole in the wall, and had an idea. It is likely that this device, which fires VX nerve gas bombs, can be used again.

Underneath the hole, the wall is also slightly recessed, with an area about the size of a coin.

I can deduce, then, that this is the vessel containing the VX nerve agent.

This is supposed to be a percussion-type opening and closing vessel that opens when the tip is struck with an external force, releasing VX nerve agent.

Then VX nerve agent apparently still has a stock at the female killer. And it can be used like a lighter to fill the gas into the opening and closing utensils.

This made me a little worried, since the female killer had taken the opening and closing utensils, her purpose was obviously to use it again. It seems that it will not be long before another VX nerve agent fatality occurs.

Except for the guns and daggers, nothing was found at the scene.

Lao Lu later investigated the identities of the three deceased and found that the identities of the three deceased were all forged and belonged to unidentified persons. Ask the neighbors around, and no one knows where they come from.

In the office of the criminal investigation team, Lao Lu took the worthless deceased investigation report and threw it helplessly on the desk.

I picked up the report and looked at it casually, except for the photos that were real and valid, the rest of the contents were inconclusive, and this was indeed the most unacceptable investigative report.

Lao Lu looked at me and said, "Don't look at it, it's worthless." By the way, has the Rubik's Cube encrypted file been unlocked? ”

I closed the case file in my hand and said, "I contacted X Weirdo in the morning, and he said that there was some progress and that he could crack it as soon as tomorrow afternoon." ”

Lao Lu's previous gloomy face eased slightly, and then he said in a deep voice: "The weapons and poison gas bombs used by Qu Mo's two killers are too bad. Sometimes handling Qu Mo's case really makes my head big. It feels like these bastards are always going to be right under our noses, and we're always helpless against them. ”

I sat down on the sofa and said, "The death of three unknown people this time has nothing to do with Qu Mo, but it has a certain relationship with Qu Mo. ”

Lao Lu frowned and said, "You can be clear, it doesn't matter what it matters, it gives me a headache." ”

I said, "The three people who died are most likely Qu Mo's killers. ”

Lao Lu said with an 'ah' sound: "Qu Mo's killer? So why did this killing angel kill his own people? ”

I said, "Apparently Qu Mo's plan was discovered by the Killing Angel. ”

Lao Lu said: "Do you mean to say that you speculated that Qu Mo wanted to entrap Yan Zhongzhi and kill the killer who killed his family for Yan Zhongzhi, and the plan to pretend to avenge him was discovered by the killing angel?" ”

I nodded and said, "Quite possibly." And the female killer killed these three people, obviously to strike first, because these mysterious three people are likely to be the killers who are ready to get rid of the killing angels. ”

Lao Lu frowned and said, "You mean that there is infighting within Qu Mo now?" ”

I said, "Yes." As I said before, there should be something wrong with Qu Mo's internal affairs, and he can no longer fully control his subordinates. However, Qu Mo was ruthless, how could he allow someone to betray him. So I guess that after the death of these three killers, Qu Mo will definitely use more powerful power to destroy the 'Killing Angel'. ”

Lao Lu sneered: "This is just right, this inhuman guy is killing each other, it is better to die a fine death, and return the society to peace." ”

I was silent for a while, lit a cigarette and said, "Old Lu, there may be another VX nerve gas case in the near future, you have to be mentally prepared for this." ”

Lao Lu shook his head and said, "You told me before that the vessel that released the gas bomb was not found, so I know what you mean." But I'm relieved now, because I know that this gas bomb will no longer be used against innocent civilians, but to poison those crooked minions. ”

I didn't answer, because Lao Lu's idea was somewhat too idealistic. The VX nerve agent is not a weapon with directional lethality like a pistol arrow, but a gas bomb. And I believe that when the Killing Angels use this kind of gas bomb, they obviously don't think about whether they will hurt innocent people. If the Killing Angel and Qu Mo's killer exchanged fire in a place where the crowd gathered, the consequences would be unimaginable.

After leaving the criminal investigation team, I came to the forensic identification center, because I wanted to personally examine the three corpses with mysterious identities, and maybe I could find some clues on the corpses.

Tang Zhenguo didn't have to wait for me outside the coroner's room today, because he took Tangtang to dance class today. In fact, I sometimes admire Tang Zhenguo, he always forcibly switches between ordinary people and my bodyguards, which requires a very sophisticated mentality to do. Why? Because my world is like a battlefield, you think about it, there is still a war during the day, and at night I have to accompany my wife and children. The kind of scene of fighting during the day and seeing corpses all over the field, and not being able to reunite with your family at night with a little shadow, that kind of mentality is not something that ordinary people can stabilize.

Of course, I also feel a little guilty that I made Tang Zhenguo, an already ordinary person, even more unusual.

Perhaps, the reason why he is so extraordinary is that God deliberately placed him next to me.

When she came to the autopsy room, Liu Lili was still lying on the unknown corpse as before, concentrating. Her little boyfriend, Lu Jianfei, is gone.

Of course, I'm not a gossip person, and I don't ask questions that don't matter the facts of the case, I like to go straight to the point of the case without ink.

I could see Liu Lili examining the body of the strongest killer. If it weren't for Liu Lili's understanding, others might have misunderstood Liu Lili's current moves. Because she was examining the genitals of this strong corpse.
