Su Yu put on protective clothing. In order to avoid accidents, he also prepared spare protective clothing and spare spare protective clothing.

Then, Su Yuliulied up a high platform and took off the strange and unknown body of the gray man in the sky.

Su Yu was very careful, but nothing happened, after all, it stopped.

Su Yu slowly transported the gray man's body and placed it in the specially prepared anatomy room.

In the dissection room, a simple dissection table was ready. The body of the gray man was sent to the dissection table. Su Yu immediately began to prepare a scalpel.

The dead can't speak, but the corpse never lies.

Su Yu knew that autopsy is a very complex discipline, and there was even a forensic doctor who was responsible for dissecting corpses and thus judging cases.

But Su Yu has never learned it. There are too many subjects and too much knowledge in the world, so it is impossible for Su Yu to learn them all.

But Su Yu has mastered the complete method of scientific investigation, so it doesn't matter even if he learns anatomy from scratch.

What's more, this is an alien, a gray man, and it may not be useful to use human anatomy.

Su Yu began to sharpen his knife. The gray people in the imperial city did not cook or chop firewood at all, so they did not have suitable knives at all.

After all, they only ate candy, but Su Yu still found some rusty knives and grind them carefully.

Anyway, it's just a gray man's corpse, and there's no need to find a sharp knife.

Moreover, because this corpse has no life, as long as Su Yu touches this corpse, it will not be stopped.

Su Yu began to dissect the anatomy. Although the knife was not very fast, it was still useful. Su Yu kept dissecting it and carefully checked the problem with the corpse.

Although Su Yu had never dissected the body, he knew very well that all organs, internal organs, and systems in the human body were synergistically working. If a person died without trauma, then there must be problems in these aspects.

Su Yu kept dissecting the disease, first checking his brain, because Su Yu was very worried about the zombie viruses and other things in these corpses.

But the result is no, the brain of this corpse is normal.

Su Yu continued to dissect the patient downward to confirm that there was no problem with his eyes, ears, nose and tongue.

Su Yu continued to dissection, and then he found that the blood flowing out of the man's heart was somewhat unusual in color.

The blood flowing out of the left side of the heart is obviously bright redder than the blood flowing out of the right side.

This shows a problem, that is, the deceased was frozen to death, and the blood in the left and right ventricles was different in color, which was the result of the inhalation of low-temperature air before death.

Moreover, many parts of this corpse are obviously shrinking.

As we all know, some parts of the human body will expand and contract. Everyone knows it, and you all know it, so you don’t need to say more.

Judging from the various special forces, this corpse has the characteristics of a frozen dead person.

"Maybe..."

Su Yu began to boldly guess: "Is this an extremely cold virus? The virus that can emit cold and freeze to death the infected person?"

Su Yu immediately extracted the cells from the corpse, but the problem arose, he did not have experimental equipment.

To make experimental equipment, one thing must be included, that is glass.

Su Yu sighed: "In such a primitive place, I can't even find an experimental equipment. I have no choice but to make it myself."

Su Yu considered himself a scientist, and it would be difficult for him to build glass from scratch.

First of all, there is silicon sand, which can be found by the river, and there is a river next to the gray imperial city.

Su Yu came to the river carefully and found that time had not recovered, which was enough to show that Su Yu had not left the threat range.

"It seems that this extreme cold virus spreads very broadly, or it is not a virus, but a certain technological creation? Or is it a psionic energy?"

Su Yu collected silicon sand and found some shells. The shells contained enough calcium carbonate, which was also one of the materials used to make glass.

"This world..." Su Yu thought, "The elemental composition is very similar to our world, no, it's better to say it's exactly the same."

Su Yu began to burn the fire, heated and mixed the materials until the materials turned into a viscous liquid, and then dipped a vacuum bamboo tube into a thick liquid, and then blew out a bottle-shaped bubble with his mouth.

Then Su Yu waited patiently, and when the bottle-shaped bubbles cooled, a glass bottle was made.

But because the raw materials are too rough, the glass bottle is also frosted, completely opaque, and has irregular shapes at all.

"The level of process and technology are indeed crucial!" Su Yu sighed. "Although science can improve productivity, after all, it is just a theory that needs to be manufactured. "

"So, technology determines the upper limit of civilization, and technology determines the lower limit of civilization, which shows that scientists and workers are the most important groups, while capitalists..."

"Not the fart."

Su Yu began to make glass cups one by one, and he became more and more skillful, and the glass cups were also made better and better.

After having the glass, Su Yu also began to polish the convex lens.

Convex lenses are essential parts for manufacturing microscopes and telescopes. They all achieve the effect of amplifying objects through the refraction of light.

Su Yu kept trying and finally polished out a suitable convex lens and then made a microscope.

However, the magnification function of this microscope is not very strong, and at most, only changes in cells can be observed.

Su Yu found the living gray man and extracted the cells from their bodies, and then raised the cells from the dead gray man.

Then, Su Yu put two different gray people cells together and observed them with a microscope.

In order to keep the cells active, Su Yu also dripped in normal saline.

Then, Su Yu began to observe, and he found that the normal cell began to lose its activity little by little and eventually died completely.

Su Yu observed carefully and found that the internal activity of this normal cell was normal at the beginning, but after contacting the cells of the dead gray man, the activity began to slow down and finally stopped completely.

Su Yu was shocked and even felt a little cold.

This is not an illusion, nor is it a psychological effect, but it is really a bit cold.

Su Yu immediately began to measure his temperature. They brought medical insurance this time, and there was a thermometer in the medical insurance.

I thought I couldn't use it, but I didn't expect it to use it.

Su Yu immediately took the measurement and found that his body temperature had dropped at least five degrees.

If Su Yu had not been an existence beyond the individual, he would have lost his temper and died at this moment.

Su Yu immediately injected himself with a high-concentration nutrient solution. As the large amount of nutrients poured in, Su Yu's cells began to function wildly, and his body temperature began to rise again.

Then Su Yu immediately demolished the gray man's house and used it to make a fire and keep it warm.

The flames burned wildly, constantly providing temperature to Su Yu, but this could only maintain the temperature of Su Yu's core.

But Su Yu has calmed down.

"I'm infected!"

“I have to find a way to solve this problem.”
