Zhou Ning understood what Zhu Xingxing meant, she felt that these things were too complicated, and they should not be cut here, but just sacrifices done here.

Before Zhou Ning could speak, Da Zhao had already come over.

"Why is there so much nonsense, not to mention twenty years ago, that is, in the sixties and seventies, there were mobile service teams showing movies everywhere, with generators and movie projectors in the car, this problem is easy to solve, but I suggest that Chen Cheng come over and take a look, these methods are not the means of professional doctors."

Liu Yufei rubbed her nose, and without waiting for Zhou Ning to say anything, she called Chen Cheng first.

"Don't wait outside, come to the No. 1 dissection room, Zhou Ning will let you distinguish, whether this suture and incision technique was done by a professional doctor, wear a mask at the door, don't come in and retch and embarrass me!"

In the last sentence, Liu Yufei turned around and whispered.

Zhou Ning has already moved out of the way, the position of the dry corpse's craniotomy has been covered with a middle scarf, and the cut skull, as well as the piece of head skin, are all placed in the tray, after all, it is a little more stimulating to the senses in this way, don't look at the doctor, the corpse can also be seen, but the irritation of the dried corpse is not something that ordinary people can bear.

After a while, Chen Cheng knocked on the door and came in, and when he saw his daughter-in-law, he was about to laugh, but was glared at by Liu Yufei, frowned and waved his hand:

"Come and have a look."

Chen Cheng ran in upside down, he knew very well what Zhou Ning and the others had gotten back, so he was very vigilant, and when he walked to the side of the dissecting table, he didn't dare to look around, Zhu Xingxing had already put the tray in front of him.

"Doctor Chen, please help me take a look, this suture figure 8 method, it seems that it is difficult to see now, in addition to this craniotomy tool, do you have any opinions, considering all this, do you think the person who did all this is from a professional background?"

Chen Cheng glanced sideways, his senses were fine, and he was also relieved.

"Forensic Doctor Zhu, don't worry, can you give me a magnifying glass? I'll observe and answer your questions!"

There was no need for Zhu Xingxing to pass, someone had already sent Chen Cheng a magnifying glass, and after observing it, everyone was not in a hurry, Chen Cheng pulled the stitches and made a loud sound.

"Hey, this thread is a bit special, much thicker than what we use now, I think we can remove it and check the material, after all, the stitches after 2000 have changed a lot, since the end of the eighties, the standard of stitches, the commonly used numbers in China are set at 0, 1, 4, 7, 10, the larger the number, the thicker the line.

And the history of the development of sutures has also changed very much, from the bottled sutures in the 1940s-1950s, to the appearance of polymer sutures in 1958, and even the PLA sutures in 1974.

But it's definitely not something that is used now, it's very tough, and it feels like it's very strong with composite materials, and as for the technique of opening holes with an electric drill, at least I know how to open a craniotomy."

Zhou Ning nodded, the sutures can be analyzed by generation, this is indeed a direction, you can ask Sister Cui after this, who is better at this.

He waved his hand at Chen Cheng, Chen Cheng walked to the dissection table, and following the direction of Zhou Ning's finger, he saw the position of the deceased's eyelid left and right to cut the eyelid fissure, and instantly understood Zhou Ning's intention, Chen Cheng observed, and his eyes widened instantly.

"Give me a pair of gloves, the deceased's eyeballs have been removed?"

Zhou Ning nodded, Da Zhao handed over the gloves, Chen Cheng put them on, Zhou Ning handed over two pairs of tweezers, Chen Cheng stiffly lifted the eyelids of the dry corpse, the eye sockets were empty, and no contents could be seen.

"It's professional enough, this frame removal technique is very professional, if you are not a professional, you won't do such a degree of professionalism, and at least leave a cut mark in the frame, you see there is no here, I think the person who did it is definitely a professional doctor, or often does this kind of thing, I don't know if the butcher takes the pig's eye like this."

Da Zhao leaned over, shook his head and said:

"The butcher doesn't take the pig's eye, and usually takes it out after the braised pig's head is cooked, after all, this thing will break if it is not touched well when it is soaked in water."

As soon as he finished saying this, Fang Dongsheng turned around and rushed out,

Da Zhao blinked and spread his hands innocently, which obviously meant to say, I didn't do anything, what's wrong.

Zhou Ning glanced at him, no nonsense, and waved his hand to signal Chen Cheng to give up his position.

"The dissection continues, and Zhu Xingxing prepares the scalpel and chainsaw."

Chen Cheng had already run out, Liu Yufei glanced at it, and followed out, Da Zhao smashed his mouth and swallowed the back, after all, the recording equipment was turned on here, otherwise he would have to say a few cool words.

Open the three chambers, take out the sternum and ribs, the hydration effect of the digestive tract viscera is not good, all of them are dried up like dead branches, attached to the posterior wall of the abdominal pelvic cavity of the thoracic cavity, and all these organs are removed.

Zhou Ning analyzed it carefully, and a conclusion appeared in Zhou Ning's mind, he had also done an autopsy of a dried corpse before, the hydration effect was not good, and he could also see that there was a residue in the digestive tract, but this one seemed to have been thoroughly cleaned up, all of them were shriveled, and there was no residue.

Zhou Ning frowned, and carefully checked the limbs of the deceased again, only to find that there were two cut marks under the bracelet, and when he was just raised for inspection, he did not find it, after all, after shriveling, the cut marks were also completely sealed, and it is estimated that bloodletting was carried out here, but it was one of the embalming measures.

Signaling Zhu Xingxing to take a sample, Zhu Xingxing cut open the stomach and small intestine, Zhou Ning took a look, although it was shriveled, the bleeding marks on it remained, and the mottled ulcer surface was dotted, Zhou Ning took off his mask and gloves.

"Sun Tietie sutured, Zhu Xingxing recorded, before the corpse died, fasted for a long time, and even did a process such as drug excretion or enema, on the inside of the two wrists, there were cut marks, and the cut marks hurt the arteries and veins, which was bloodletting, in preparation for the embalming of the corpse.

Let's sort it out, except for the traces of the head electric drill on the head and the wrist suspension injury, there are no fractures, and the water is fasted for a long time before the sacrifice, and it is excreted by enemas or laxatives.

Initially I thought that the deceased was anesthetized and could not resist the struggle, and seeing the deep cut on his wrist, he should have been bled first, and when he reached a certain amount of coma, he was cut off from his eggs, his eyes were gouged out, his tongue was cut, his teeth were extracted, his skull was cut, and he was filled with mercury.

After doing this, they are smeared with special pharmaceutical powder, and the cloth wrapped in the shell is suspended and dried in the required posture, and we don't know whether the sacrificial technique is professional or not, but all the cutting techniques and the selection of sutures are very professional, and they should be medical practitioners or professionally trained personnel.

The cause of death of the deceased was hemorrhagic shock, and the non-decomposition of the corpse was related to the above-mentioned operations, and as for the time of death, the preliminary judgment is about 20 years, and the specific time will be determined by the identification of sutures and wrapping materials."

Zhou Ning waved his hand, Da Zhao turned off the recording equipment, Sun Gaotie had also completed the stitching, the dried corpse was wiped clean, covered with a white cloth and pushed out, all the doors and windows were opened, after all, a large amount of mercury was poured into the body of the deceased, even if the ventilation system was turned on, they would cut the body of the deceased, and it would still volatilize a part.

Chen Cheng came in at this time, and when he saw that this side was over, he trotted over.

"I checked, according to the size of the craniotomy aperture you mentioned, the drill bit of an ordinary electric drill M5 can be adapted, not a specific tool.

Also, I think of a point, if according to your analysis, this was a sacrificial event twenty years ago, then how did this mercury get it? Although this is a small child, the amount of mercury injected into each of the eight children is considerable.

A normal seven or eight-year-old child's brain weighs 1,350 grams, and the texture is similar to that of water tofu.

After all, the specific gravity of the brain is not much different from water, about 1 gram per cubic centimeter, but the specific gravity of mercury is 13.59 grams per cubic centimeter, I don't understand the difference, but it is many times worse, right?"

Speaking of this, Chen Cheng retched, this was disgusting what he said, Zhou Ning understood and patted him on the shoulder.

"I understand what you mean, one person needs a few catties of mercury, and eight people need a larger amount, and dozens or even more than a hundred catties of mercury are made at once, this is not a small amount, and you can inquire from this angle, right?"

Chen Cheng clapped his hands.

"That's what it means, or do you know what I mean, Liu

Yu Fei has to stop me from telling me."

Liu Yufei gave him a warning look, and Zhou Ning waved his hand and said:

"Sister Fei, don't stop Chen Cheng, thanks to him this time, the autopsy here has also ended, and another dried corpse is soaking in Lu Feier's solution, do you want to ask Fang Da, did the respected old lady bring it?"

And the coffin is not said to be transported down today, we also have to look inside, if we don't find it, we still have to go to the site to investigate it for a second time, after all, we didn't bring any tools last time, whether it is the first scene, we need to check carefully."

Liu Yufei nodded, obviously agreeing with Zhou Ning's judgment.

"Said that the old lady will be here soon, let's go to the front and wait, the office next door has just sent a whiteboard, I found that it is the same as your office, it is double-sided, leave someone to sort out the content of the anatomy, as for what to do next, we will talk about it later."

Zhou Ning nodded and glanced at everyone.

"Zhu Xingxing will take someone to sort out the autopsy records, a few of you will take a look at the temperature of Lu Feier's solution, help Zhu Xingxing improve the discoveries in the past few days, and see if there are any omissions in us, Fang Da didn't send a few people over, you want to follow the trace examination, Lao Yang, you teach you the basic knowledge, and then you can come out with us on the scene."

Zhu Xingxing called everyone to leave, and at this time, Fang Dongsheng, whose face was pale, came back and nodded apologetically to Liu Yufei and Zhou Ning.

"I'm sorry, I really can't help it, we have a dead man's criminal case here, and it's a big deal when it comes out, and the forensic doctor Lao Zhang can't get it, so I directly contacted the provincial department and came over to help, I really haven't seen the autopsy."

Zhou Ning shook his head.

"It's okay, this kind of professionalism can't stand it, we also hold on to it, by the way, Fang Da, is that old lady here?"
