"I heard you're going to change? Will you change my line? ......”

"I need to stop the bleeding now, I'm dying,......"

"You change, you change one, I'll take a look, and I'll stop the bleeding for you."

"Alright, alright, I'll make you ,......"

···································

In the interrogation room, this is the dialogue between Shadow and Yang Mengmeng.

After a few tosses, the shadow was about to die. But Yang Mengmeng still asked him to change one.

But at this time, the shadow was extremely short of blood and water, and his body only turned black like black charcoal, and he regained his human form.

"It seems that a large amount of melanin has been deposited in his body, coupled with his characteristic tights, which allows him to wander like a shadow."

Yang Mengmeng made an analysis in an instant, while Ye Xiuwen could only watch from the sidelines. Yang Mengmeng's theory is not something that ordinary people can understand. But her skills are not to say, Ye Xiuwen has learned anyway. She could make a radio in half an hour. And just with the materials in her room.

Her room was a labyrinth, but she was able to find everything she needed in a fraction of the time.

So in Ye Xiuwen's eyes, Yang Mengmeng is a magical person.

"Stop the bleeding, big sister, I'm really going to die this time."

The shadow was pale, and when he transformed just now, the amount of bleeding was heavy again. Although it was as if there was no blood left in his body.

But at this time, Yang Mengmeng took a tweezer and poked the wound on the shadow's body with cotton: "You don't have to worry, I won't let you die, I have to take a little blood sample now, otherwise the bleeding will stop, and I still have to use a needle to pull it out, isn't it?" ”

Yang Mengmeng asked very cutely, but the shadow didn't think she was cute at all. Because the girl was poking his wound with tweezers and cotton in her pocket. And if he hadn't fallen into a state of weakness, I'm afraid Yang Mengmeng would have died a hundred times.

"Huh? Why don't you use the blood on the ground? The shadow suddenly figured out that he had so much blood on the ground, and it was not enough to use the ground, so why should he poke it in his wounds?

"The blood on the ground has been contaminated with bacteria, while the blood on the wound is fresh. The two are incomparable.

Here comes that pair of scissors! ......”

Yang Mengmeng suddenly asked for a pair of scissors. The shadow hurriedly howled, "What are you going to do with the scissors?" ”

"The flesh of your wound is stuck to your clothes, and I don't cut it, how can I help you stop the bleeding? You're going to die. Yang Mengmeng said very seriously. But before the shadow could answer, Yang Mengmeng had already started to do it.

"Ahh .......”

The shadow screamed, and its body began to twist. On his forehead were large beads of sweat. Screamed, "Are you the devil?" When you are treated, don't you give me an anesthetic first? ”

"I'm sorry sir, I'm a scientist, not a doctor." Yang Mengmeng said apologetically.

"Ahh ...... If there is no heavenly principle, don't you have a doctor in Huaxia? .......”

The shadow screamed and wailed in pain.

"Originally, I wanted to find you a doctor to treat you. But you want to run, so I think, Dr. Yang is a better fit for you. ”

Ye Xiuwen sat on the table at this time and smiled.

At the same time, the shadow finally understood why the white devil and the black devil didn't run away just now. It turned out that the Huaxia black wolf sitting on the table in front of him was the real devil. He was taking revenge for his escape.

At this time, he had nothing to say, he could only endure Yang Mengmeng's treatment.

Yang Mengmeng's speed is still very fast, and after losing a large area of carrion, he made a boxy cotton wool to wrap the wound on Shadow's back.

The shadow also had an injury to his leg, but at this time, when Yang Mengmeng was treating the wound for the shadow, the shadow was no longer screaming, because the shadow had fainted in pain.

But this is better, Yang Mengmeng is even more unscrupulous when she starts to do things. A large number of fragments of shadow clothing were also cut out and used as evidence bags.

"Is there anything wrong with this dress?" Ye Xiuwen asked.

"The garment is very stretchy and very waterproof. There is a certain ability to resist impacts. Yang Mengmeng explained.

"And his ability to turn into a shadow?" Ye Xiuwen asked.

"The preliminary judgment is that there is too much melanin in his body, which will fill the whole body under special conditions, just like Africans.

It's just that the pigment of the African is always deposited on the surface of the body, and the melanin of the shadow is hidden in his body. It can only be excited after certain conditions.

And such a genetic mutation may be due to his African ancestry," Yang Mengmeng explained again.

"Hehe, that's kind of interesting." Ye Xiuwen laughed. However, at this time, Luo Han said on the side: "Is this still not right? His transformation into a shadow is not as simple as turning black, his body will become thinner. ”

"This is also very easy to explain, because the human body is 70 or 80 percent water, so if the human body can be liquefied through many methods, it is also possible." Yang Mengmeng explained.

"But are human bones hard?" Luohan was still puzzled.

"The main component of bones is calcium, which can be very hard, but liquid calcium can also be present.

I just saw a subtle change in the shadow, and when the shadow changes in the body, it doesn't suddenly become a shadow. Instead, it will first turn black and then gradually liquefy.

And this liquefaction is like oil. I think oil, you should all be familiar with it, right?

Studies have shown that it takes at least 2 million years for oil to develop, and that the oldest reservoirs discovered today are 500 million years old. Most of the oil was produced during the Jurassic period.

During the long history of the Earth's continuous evolution, there were some "special" periods, such as the Paleozoic and Mesozoic Eras, when after the death of a large number of plants and animals, the organic matter that makes up their bodies continued to decompose, mixing with sediment or carbonate sediments and other substances to form sedimentary layers.

As the sediment continues to accumulate and thicken, the temperature and pressure rise, and as this process continues, the sedimentary layer becomes sedimentary rock, and then the sedimentary basin is formed, which provides the basic geological environment for the generation of oil.

Most geologists believe that oil, like coal and natural gas, was formed gradually by ancient organic matter through a long period of compression and heating.

So according to this theory, oil was formed by the transformation of prehistoric marine animals and algae corpses.

Plants on land, on the other hand, generally form coal, but the carcasses of animals are buried under thick sedimentary rock after a long geological age, where the organic matter mixes with silt.

At high temperatures and pressures underground, they are gradually transformed, first forming waxy oil shale and later degenerating into liquid and gaseous hydrocarbons. Because these hydrocarbons are lighter than nearby rocks, they penetrate upwards into nearby rock formations until they penetrate into the tightly impermeable, inherently empty rock formations above.

In this way, the oil that comes together forms an oil field. By drilling and pumping, one can get oil from the oil fields. Geologists refer to the temperature range in which oil forms as the "oil window".

Therefore, according to this theory of oil formation, it is feasible for the human body to liquefy into a black substance,...... Yes, this method is possible, but I still need my research as a scientific basis, you wait a minute, I'll do some simple experiments first, this opportunity is really rare, I also need a handful of his hair,......"

Yang Mengmeng said, and also took a razor to shave a handful of Shadow's hair for research.

Ye Xiuwen was a little speechless at this time, and even regretted letting Yang Mengmeng come,......
