"This cause of death is unprecedented." After a while, Liu Xuan put the information in his hand on the table and said.

"Yes, on the surface, the main cause of death of the man named Qiao Tian was throat slitting, but in fact, his internal organs were broken before his throat was slit."

"What would be the normal cause of death?" Chen Ziyan looked at the analysis on the autopsy report and asked.

"Generally speaking, the cause of death is usually caused by extremely strong external force. Car accidents can cause such broken internal organs. In addition, there are sound waves. However, this killing method is only used abroad and domestically.

There is currently no research on sound waves, and our country’s management of sound wave equipment is extremely strict, so this situation can basically be ruled out.”

Looking at Chen Ziyan, Qin Siyu gave his own explanation.

"Is it possible to cause this kind of death with human power?"

Then she spoke, and Sun Jianyan asked her.

"Unless this person has the power of bullfighting, it is absolutely impossible. But I don't know if hard qigong can achieve this effect. There are also qigong that I have never seen before. As for the others, I can't think of them at the moment."

Shaking his head, Qin Siyu said that he did not know.

"This is indeed very questionable, but since we are talking about traditional martial arts, I think this can be used as a reference. After all, in our vast country, the traditional things still have their essence, and for things we don't understand, we need to go

Let’s get acquainted with it again, and then look up the information on this aspect and see if there are professionals who can answer it for us.”

"Well, leave this to me. It just so happens that there are no anatomy matters in the bureau recently. I can also increase my knowledge, otherwise it will be really embarrassing to face this kind of situation in the future."

Nodding, Qin Siyu took the initiative to take over the task.

"Are the bodies of the woman and the child in the same condition?" Liu Xuan asked her as he continued to speak.

"No, he just died from a normal stab wound. The murderer's main target was Qiao Tian."

Listening to this answer, Liu Xuan couldn't help but ponder, and then spoke to Sun Jianyan: "Old Sun, I remember that you dealt with a fatal fight in a martial arts school last time, right?"

"Yes, why are you asking this all of a sudden?" Sun Jianyan answered Liu Xuan's somewhat confused question.

"Since everything is still unclear at the moment, and apart from the kindergarten, only the martial arts aspect can be used as a clue to trace, I think we can go to the martial arts gym in the same city to see if anyone knows Qiao Tian. We can't just sit idle."

Hearing this, Sun Jianyan nodded: "Then I will lead people to search for how many martial arts schools there are in the city later, and then take a trip."

"Well, thank you for your hard work."

"Have you retrieved the surveillance data?" Liu Xuan turned to Zhang Chuge again and spoke.

"I've been there, but just ten minutes before the death was determined, all the surveillance cameras along the way were destroyed. There was no trace of the murderer at all. And all the shots in the last scene were of a flying stone. We

I simply judged the speed of the stones in the video and found that they are very powerful."

"That means the murderer knows all the surveillance locations in the community, right?"

Asking directly, Liu Xuan rolled his eyes and seemed to have an idea.

"You can say that, Captain Liu, what do you mean?"

"Since the murderer is familiar with the monitoring location of the community, it is enough to show his understanding of this community. So now there are only two possibilities. One is that he is from this community himself, and the other is that he came here in advance and touched some

, but no matter which one it is, he will appear in the previous surveillance of the community, so we have to adjust the surveillance again, the one from the previous week."

With a firm tone, Liu Xuan seemed to have caught a new clue.

"Then should we go to the kindergarten first or adjust the monitoring?" Zhang Chuge asked, his tone hesitant.

"Just leave the monitoring to me and Ziyan. Your original plan remains unchanged."

Hearing this, Zhang Chuge nodded.

After arranging all the tasks, Liu Xuan lowered his head slightly and tapped his fingers on the table, seeming to be thinking. After a while, he raised his head again: "Everyone has other ideas.

What?"

No one spoke, everyone looked at each other, as if they didn't understand what Liu Xuan meant.

"I just think that if we check this way, the efficiency will be very slow and it will consume a lot of manpower. I want to see if you have any good suggestions."

"Right now, all the clues are unclear. What else can we do? You are impatient, Old Liu."

Putting his hands on the table, Sun Jianyan spoke to him.

"Hey, it's possible. If that's the case, let's just do it. Everyone should be busy with their own affairs." Shaking his head, Liu Xuan stood up and made the final decision.

After everyone walked out of the conference room, Liu Xuan was still sitting on the chair, lost in thought for a long time.

Looking at his appearance, Chen Ziyan sat next to him: "Brother Liu, actually I had an idea just now, but I didn't dare to say it because I wasn't sure."

"Oh?" Liu Xuan raised his head and commented, his eyes brightening.

"I think that no matter what the case is, there is no possibility of no clues, because no matter how cunning the murderer is, he cannot have no clues, because when a person commits a crime, no matter what mood he is in, there will be some clues.

Negligence, let’s just talk about this case. Assuming that the murderer has high martial arts, then it is worth verifying that he committed such a murder. This means that even if they had a grudge, the deceased should have better martial arts. As a martial artist, I don’t think they

Will stop practicing. Even if the murderer's martial arts surpasses the deceased, the deceased will not be able to fight back. And from the traces at the scene, we can confirm that the murderer was knocked away by a blow and hit the shoe rack. This means that there is not a huge gap in strength between the two.

.”

Listening to Chen Ziyan's analysis, Liu Xuan's eyes brightened and he motioned for him to continue.

"So under such circumstances, it is impossible for the murderer to be unharmed. Since he is injured, he must go to the hospital for treatment. And because of the identity of the murderer, he will definitely not go to a big hospital. So we can treat him from the surrounding small clinics.

Investigation, also, since there is no trace of the murderer at the scene, it means that the murderer must be fully armed and take measures, and because he abused the corpse, the blood will inevitably splash on him, so he will definitely destroy these things

, but even if the things on his body can be burned, he can only throw away the knife, and the murderer is so cautious that it is impossible to throw it away in the trash can, so the most permanent solution is to throw it into the river or sewer, and in such a place,

They are usually monitored, so can we contact the transportation bureau to request the monitoring of some road sections? Try looking for it?"

Listening to Chen Ziyan's words, Liu Xuan nodded slightly: "Although it's a bit like finding a needle in a haystack, it's not useless after all."

"Well, since we can't find intuitive clues, we can only use this method. Also, although the media method cannot be used, the bureau did not say that we cannot investigate through the community? Where did the murderer come from? The vehicle or the vehicle

Walking? Or have you encountered strangers when traveling between floors in the same building? Once found, it will be a major clue and the most intuitive witness. Although the deceased died at one o'clock, he was going to someone else's home after all.

It's impossible to start fighting right away, right? Even if it really starts fighting right away, then two people of similar strength will not directly determine the winner. If we look at it some time in advance, this is the time when many people go shopping for groceries.

So it is very possible that someone has seen the murderer. We didn't think of this last time we visited, so I think it is necessary to walk around."

"Okay, although it sounds like it takes a lot of effort, it's better than finishing one thing and then being helpless. Let's go. You are really good."
