After checking the kidneys, the next thing to be checked is the brain, because there is no hand drill and milling cutter, so there is no way to use the normal "point drill" craniotomy method, but, of course, this is difficult for our male protagonist Du Lin.

I saw him groping for a while in the occipital part of the back of the deceased's head, as if looking for some acupuncture points, and after finding it, Dührin marked the place with a silver needle, and then used a scalpel to cut along the deceased's hairline, and removed the scalp, revealing a white skull (Pudding: You look first, I'll go and vomit for a while).

The silver needle is removed, and then the scalpel is inserted into the exact position of the pinhole, and a cross-shaped incision is made horizontally and vertically.

As if he suddenly remembered something, Du Lin stopped what he was doing, and motioned for Ji Ruoming, who was concentrating on the dissection next to him, to stretch out his hand.

Ji Ruoming stretched out a right hand that was still stained with kidney tissue fluid, and Durin grabbed the hand and asked her to touch the skull near the incision on the back of the deceased's head with her fingers.

After touching it a few times, Ji Ruoming's eyes lit up, "Soft?

Du Lin nodded, the child can be taught, and he understood what he meant, it seems that this little girl really has a talent in this area, and when she goes out, she can be introduced to Shui Guochang and a belt.

Durin then used a scalpel to cut the muscles and ligaments of the jaws on both sides, and made several incisions along the "herringbone suture", "scaly suture" and "coronal suture" on the skull. Gently pushed Ji Ruoming with his hand, let her stand farther away, and then turned the deceased's body over and turned it into a prone position, holding the neck of the deceased with one hand, and the other hand on the incision at the back of the head, and with both hands, the deceased's skull was lifted from the coronal slit at the top door, revealing pale red and almost white brain tissue (my God, why am I writing this? This is a medical text, it shouldn't be harmonized because it's too bloody, right?).

Du Lin glanced at Ji Ruoming again, she still looked interested, and took the initiative to take the part of the skull that was removed from Du Lin's hand, and wondered whether to look at her Yongnian uncle's brain first, or study this skull first.

Confirmed the eyes, born forensic man. This little girl's refusal to do forensic medicine is definitely a big loss to the Chinese forensic community.

Duhrin left her alone, cut open the dural mater, and used his fingers to pluck the cerebellum a little from the ventricles, so that it was easier to observe the "occipital side" of the cerebellum adjacent to the internal auditory canal.

Sure enough, as Durin expected, this part of the cerebellum on the occipital side has developed lesions, which indicates that the inflammation of the deceased's inner auditory canal has invaded the cerebellum.

The brain controls people's thoughts, so the cerebellum controls people's actions, and if there is a problem with the cerebellum, people cannot walk normally and lose the ability to coordinate movements.

But even so, it won't let the patient die!

Doolin continued to pull out the brain tissue until the deeper part of the brain stem was exposed, and Doolin finally understood what caused the death of this patient named Ji Yongnian - brain stem damage.

If the human brain tissue is compared to a computer, then the brain is the CPU and the hard disk, responsible for thinking and memory.

The cerebellum is a computer system that coordinates the movements of various parts of the body.

As for the brain stem, the function is very simple, it is the "POWER button" on the computer, which is only responsible for one thing, that is, life and death.

People can survive without brains, and it was reported that a government civil servant in Gaul went to the hospital for a physical examination, and the doctor almost jumped out of fright when he did a brain CT scan - he didn't have a brain!

The person had only a large amount of cerebrospinal fluid in the ventricles, and the brain tissue was squeezed as thin as paper. But this situation has no impact on the normal life of this person, he can marry a wife and have children, the children are also healthy, and he can also work in government agencies, although his intelligence is a little worse than that of a normal person, but it is far from being mentally retarded.

If there is no cerebellum, the impact is more significant, but acceptable. There are many patients who have had their cerebellum removed due to cerebellar injury or other reasons and can continue to survive.

For example, a normal person can quickly draw a straight line on paper with a pen, while a person with cerebellar injury does the same movement slowly, erratically, with many corrections in the middle.

They are able to control their bodies, but their accuracy is greatly affected, their coordination is reduced, they lose the ability to maintain balance and body posture, they walk slowly, and they fall easily.

However, if there is no brainstem, or even the slightest damage to the brainstem, then there is no if, and it is directly "OVER".

Ji Yongnian's brain stem was affected by the virus, which produced organic lesions, causing him to die quickly in a short period of time.

This shows that the virus not only causes deafness, but also kills people at worst!

The virus must be eradicated.

Durin's face was serious, and the first thing he had to do now was to eliminate the source of the virus - those bats!

Du Lin packed up his things, rearranged Ji Yongnian's body, and let Ji Ruoming go back to her own cave, and then hurriedly ran down the steps down the mountain wall, found He Wenjing in the farmland, and briefly talked about the autopsy.

"Second sister, we must kill all those bats immediately, otherwise not only will everyone here be infected, but the bats will also spread this deadly virus outside, and the consequences will be unimaginable. ”

"Okay, I'll figure it out right away. ”

He Wenjing gathered a few middle-aged men, prepared a pile of firewood, and piled it in front of a cave.

"This is the cave where we usually dispose of garbage, and I have them pile up all the garbage that can be burned here and set it on fire. He Wenjing introduced.

"What about bats? It's not possible to catch them one by one by manpower, it's not inefficient, and if you get infected, it will be bad. Durin said worriedly.

"Don't worry, you second sister and I have a way. ”

I saw He Wenjing walking alone to the area where the bats lived, and a few minutes later, hundreds of bats hovered above He Wenjing's head, and with He Wenjing's footsteps, they came to the mouth of the cave where the firewood was piled up.

One of the largest bats fell to the ground, facing He Wenjing, as if talking to her, He Wenjing also nodded and spoke for a while, and after chatting for a while, the big bat rose into the air, led the bat swarm to turn around in the air, and plunged into the cave, and the other bats also flew in.

He Wenjing, who was outside the cave, burst into tears at some point.

Du Lin gently patted He Wenjing on the back, lit the firewood at the entrance of the cave with a burning torch, and then threw the torch into the cave as well.

In an instant, the fire scorched every corner of the cave like purgatory, and the bats made a dying "squeak" sound in the cave. Outside the cave, not only He Wenjing, but also several spirit beast sect members also shed tears.
