The long night has finally passed, perhaps as the year is approaching, and the students are on vacation, and the most dealt with this night is family conflicts and fireworks.

The former, most of them are because of children's education problems, dad thinks that he can watch TV and play with mobile phones moderately, and mom thinks that he can't do it for a second, he can't keep arguing, and when his temper comes up, he will make trouble, and he will call the police for this trouble, and he will give them all such services with police resources.

The latter, Xu Zheng can't remember how many years fireworks and firecrackers have been banned, banned every year, and can't be stopped every year, but the above has not changed the policy, and it is not them who are affected by the front-line police and comrades of comprehensive law enforcement.

Anyway, as long as it's not too much, Xu Zheng won't care, and as for the children and young people who run away after the fireworks, Xu Zheng won't chase them.

Some are small Internet celebrities who are engaged in live broadcasts and have not become popular, in order to become famous for what traffic, live broadcast fireworks, you catch it, just send him traffic, fine money to close his account, and it didn't take long for him to change to a new number for live broadcast.

Busy until seven o'clock in the morning, Xu Zheng breathed a sigh of relief, if there is no collective incident, the police on duty can rest for a day.

Xu Zheng didn't eat breakfast, because he was still going to go to Forensic Doctor Lu to lie down, and everyone had looked for him twice, and he didn't want to go if he didn't go.

It was not polite to meet with Forensic Doctor Lu, Xu Zheng directly asked to see the condition of the skull first.

Now in front of Xu is a skull that has been restored with soft plastic clay, and next to it is a forensic doctor in his 30s.

When Forensic Doctor Lu came over with Xu Zheng, the forensic doctor quickly stood up, "Teacher, is this Master Xu Zheng Xu?" It's so young. ”

As he spoke, he stretched out his hands, but when he saw that his hands were full of yellow mud, he hurriedly smiled embarrassedly and gestured to Xu Zheng.

Forensic Doctor Lu hurriedly introduced, "Xiao Xu, this is Jiao Guangnan, a forensic doctor from Danyang City, and also a student of mine, no, the skull restoration made by all of us can't be recognized, this looks like the New Year, the eucalyptus has not advanced at all, and the pressure of the Danyang City Branch is not small." ”

Danyang City is a county-level city, the local renovation of a section of cement road, but when the crusher operation, found a lot of white bone fragments, although these white bone fragments have been integrated with dry and hard cement, but broken into pieces of cement, can still find that this is human bones.

Now many workers have seen it, so the local criminal police brigade is required to break it as soon as possible.

They were now able to collect a quarter of the skulls, mainly the occipital bone and mandible, as well as other fragmentary fragments of the skull.

When Xu Zheng was carefully observing, Jiao Guangnan continued to introduce the situation to him, they all smashed cement blocks by hand in this 100-meter section of the road, and only so many were found so far.

It is estimated that in order to find out all of them, it is necessary to break all the cement roads 10 miles away, "This project is very big, whether to do it or not, the sub-bureau can't do it, but what we can do now is to identify the victim, and then find the murderer." ”

Xu Zheng nodded slightly, so many bones had to be broken and mixed into the cement mixer, and when it was paved on the road, it had to be checked that there could be no bones on the ground, which was obviously a gang.

Either paving workers, or contract foremen and paving workers, as long as the builder of this section of the road is found, the eucalyptus is not difficult to break.

He casually asked, "Have you detected the age of the deceased?" ”

Forensic Doctor Lu explained to Xu Zheng, "Because cement is highly corrosive, it has a great impact on the results of the identification, and the murderer also boiled the body of the deceased, leaving only the bones, which were broken and finally mixed with cement."

So, looking at bone density to measure age is a problem. ”

Xu Zheng is interested in this eucalyptus, but it is not very big, "You did a 3D model of the skull, right?" Let me see. ”

Looking at the 3D data map on the computer screen, Xu Zheng began to simulate in his mind, the corrosiveness of cement is indeed large, coupled with the density of these bones compressed by the cement after it is dry and hard, and the vehicles that often pass on the road make the bones slightly deformed.

These problems have to be taken into account, and the 3D data model in front of Xu Zheng is based on the current data of the skull, which does not take into account the problem that the skull has been deformed for so many years.

But how can they know if the data has to be changed, how many forensic doctors have to change?

Xu Zheng also has no experience and no data.

As for the restored skull in front of him, it was also done by Forensic Doctor Lu with his feelings and experience, and now the result of his skull restoration is out, obviously, it failed.

"Master Lu, Master Jiao, for such a compressed and deformed skull, I don't need to say it, you also know that I definitely have no experience.

What I can do is just like you, trial and error, you see? ”

Xu Zheng said very clearly, he can promise to do it, but there is no guarantee of the success rate, now this skull, no one dares to guarantee it, unless the forensic doctor Yuan in Nanhai Province, who has already retired, is 30 years younger, it is estimated that he will dare to say 90%.

"That's okay, Xiao Xu, you do the skull restoration, and then hand it over to the Danyang City Branch, and that's it if you don't succeed." Dr. Lu assured Xu Zheng.

"Okay, let's start now, I'll go home and sleep when I'm done." Xu Zheng also simply agreed to start this.

Doctor Lu persuaded: "Xiao Xu, why don't you go back to sleep first, and then do it when you wake up..."

"What is this dragging, my colleagues in Danyang City are in a hurry, the dead are big, I can hold on for a while."

"Uh..."

After Xu Zheng finished speaking, he began to do it, found a brush and water, and had to remove the soft plastic cement on the skull first. Remove the mud, brush it clean, wipe it with a towel, and then gently rub the surface of the occipital bone with your fingers, design the next idea according to the lines on the skull, and push it backwards to the entire skull step by step.

It's easy to say, Xu Zheng deduces while doing it, and sometimes it feels wrong, so he has to start over, and it is the deformation of this skull that causes the variables deduced by Xu Zheng to increase exponentially.

Because there is a part of the mandible, it can be directly judged to be female, and the mandible is slightly smaller, indicating that the skull is not large, but considering the reason for cement compression, Xu Zheng judged that the skull should be slightly larger than the 3D data simulated by the computer.

In this way, while deducing, he touched the soft plastic cement on the skull, and before he knew it, it was more than three o'clock in the afternoon, and finally, a restored skull with closed eyes was completed under Xu Zheng's hands.

He looked at it for a moment, "Master Lu, you bring me a pen and paper, and I'll draw an eye." ”

"Master Xu, my master and Senior Brother Cui can't hold it anymore, so we will go back and rest first, and let me help you here." Wang Dong, the apprentice of Forensic Doctor Lu, stood behind Xu Zheng with a pen and paper at this time, and respected and admired Xu Zhengxian very much, and even changed his title to Master Xu.

Xu Zheng didn't care about this, took the pen and paper, swished, and spent another ten minutes drawing a pair of eyes, "Wang Dong, don't you happen to know how to operate the software?" That's right, you can do the rest of the work. I'll go back first. ”

After speaking, Xu Zheng stood up, his head was a little dizzy, and at this time he felt tired, hungry and sleepy, his whole body ached, and his feet were numb.

However, this time his gains were not small, and after 7 hours of continuous work, his mind sank, so that his understanding and techniques of skull restoration had reached the master level.

This is also thanks to the advanced forensic technology given by the system.

Before going out, Xu Zheng said to Wang Dong who sent him: "If the results come out from your side, you can send them directly to the Danyang City Branch, and let them find them directly by the map." ”

Wang Dong was a little suspicious, this compressed and deformed skull, the master said that it would be trial and error, but when he finished it in an hour, he handed it over to the Danyang City Branch, which took the photo and visited within a radius of 30 miles, and was recognized by people at 9 o'clock in the evening.
