A few days later.

Several cars arrived in Laoshan County in a hurry.

The Institute of Biology of the Kyushu Academy of Sciences has been vacated as a large laboratory, fully equipped, and refrigeration technology has been used to reduce the temperature in the house and ensure that the body does not decompose. 、

Li Zhen and the others all put on protective clothing and waited for a long time with glass masks.

It was determined that Wang Tongxue was poisoned, but no one could be sure what kind of poison it was, and for the sake of safety, protective measures must be taken.

"Here we are."

Someone shouted outside.

Li Zhen sat on the high place in the room and waved his hand: "Send it in." ”

A moment later, several people walked in carrying a large coffin with heavy steps. The coffin was still dripping and wet. That's the water droplets that the ice cubes put in it melt away.

With a 'bang', the coffin fell heavily to the ground. The group of people led by Lin Guofu looked at each other for a while, and immediately opened the coffin.

The body in the coffin was well preserved. But the smile on the face of the deceased made people feel weird.

But how can a scientist be afraid of these things? Lin Guofu and the others looked at the corpse without any mood fluctuations, and carried the corpse to the test bench with their hands and feet.

And Wang Shun's people are obviously also experienced people, and they spread a very thick plastic sheet under the coffin, and under the plastic sheet is ice cubes. In this way, the temperature in the coffin is very low, but there is no water vapor invasion.

Wang Tongxue has been dead for several days, and it is just a few more corpses.

"Knives."

Lin Guofu stretched out his hand, and the assistant behind him immediately handed over an extremely sharp knife.

'Puff puff'

A knife quickly cut the thigh artery of Wang Tongxue's corpse.

A clump of black-red blood flowed out, and the blood flowed like jelly, and it flowed a lot.

Lin Guofu immediately put it in a sterile container: "Take the blood for testing." ”

"Yes."

"Look at the cells, what I taught you, don't forget. He is poisoned, so there must be ingredients in the blood, and you must not forget to compare. ”

"Got it, Dean Lin."

“……”

Lin Guofu got busy, and immediately began to study the corpse after taking the blood.

Ding Zhenzhen sat next to Li Zhen, a little nauseous and retching.

Li Zhen glanced at her and didn't say anything.

Ding Zhenzhen said with some embarrassment: "This person's death is so terrifying, I estimate that I will have a nightmare for a few days." Why is he laughing? It's really scary that the corpse is still laughing. ”

Li Zhen still didn't speak.

Jia Liping said softly beside him: "It's because I don't know why he still laughs after he dies, so he has to test it." ”

"Can this be tested?"

"It's hard to say, it's mainly because I don't know what ingredients are used. This poison is too powerful......"

Li Zhen watched from the side, a flash of doubt flashed in his eyes, and his heart was full of doubts.

Zhang Zhi told me that there is a way to die called euthanasia. Wang Tongxue's death is very consistent with euthanasia, because someone injected him with a certain drug. Then it is clear that his killer could not bear to make him so miserable, but yet he had to kill him.

Why do you have to kill him? What exactly does he know?

The most important question, Li Zhen almost ignored, but in fact, many people ignore this question.

He who has the ability to mysteriously take him captive and kill him secretly. Why throw him into the wilderness? Was his body found on purpose?

If you kill someone in secret, it is actually difficult to find a place to bury it in the wilderness. But it was sloppy and rough in the wilderness, like the way a robber killed someone and disposed of a corpse.

Moreover, the person who was able to come up with this euthanasia drug. According to his mysterious character, he should like the situation where he can't see people alive or dead, and he should like to create a mysterious state. Why should people find the body?

In fact, if you want to hide something, let Wang Tongxue disappear mysteriously, the effect is better. And that person is absolutely capable of making people never find Wang Tongxue's bones, and the person who can make euthanasia, he makes a strong acid, and it shouldn't be a problem to turn the corpse into a corpse.

Li Zhen couldn't figure out these problems, and always felt that this force was a bit inconsistent in doing things, and the donkey's lips were not in the horse's mouth.

But Li Zhen is basically certain that it was definitely not the government that did it. Because the Kyushu Academy of Sciences has not researched this euthanasia drug, the government does not have the ability to do so.

It's not that Li Zhen looks down on others.

The main reason is that the Kyushu Academy of Sciences is fully developed, while the government pays more attention to the development of physics and does not pay much attention to chemistry and biology. There are many academies and laboratories in the country, and they are basically physics. It's not enough for someone else to work on something like that.

Li really thought about it, and saw Lin Guofu stabbing Wang Tongxue's chest.

"Ahh

Ding Zhenzhen exclaimed in surprise, and hurriedly closed her eyes, unable to bear to look.

And Jia Liping also turned his head away, not daring to look.

This picture is too bloody, and the two admire it in their hearts, how did this Lin Guofu and his group manage to be without waves?

After his chest opened, Lin Guofu suddenly shouted: "Master Li! I've found a problem. ”

Li Zhen nodded flatly: "You say." ”

"Wang Tongxue died of heart failure."

Lin Guofu said excitedly: "The process of Wang Tongxue's death is only fifteen seconds at most, and his heart quickly fails and dies within fifteen seconds. ”

Li Zhen didn't ask Lin Guofu how he knew that it was within fifteen seconds, and he could still trust Lin Guofu's experience, but Li Zhen frowned. Even more certain, this is euthanasia.

Zhang Zhi said it to himself.

The purpose of euthanasia is to allow some death row inmates to die without pain. Or it is used for some severely disabled, suffering from illness, severe mental illness, and is a humane way for the hospital to end their lives.

And euthanasia is stipulated, and it must be within 20 seconds, so that people can die completely painlessly. It takes twenty seconds for people to feel the unparalleled joy in the world, and for twenty seconds, people die before they have time to be afraid. Try to be as humane as possible, and make him as happy as possible.

So it's usually about fifteen seconds to die.

It can't be long.

And there are only three ways to make people die quickly and happily within fifteen seconds.

Li Zhen didn't tell anyone from the College of Chemistry, but in fact, people from the College of Chemistry would do this, but they forgot.

The first is cyanide.

The second is a large amount of anesthetic combined with respiratory suppressants.

The third is the injection of coagulants with high-intensity tranquilizers.

Cyanide, the Faculty of Chemistry will ......

Because when he once attacked the Eight Dragons City, he attacked the city with cyanide, and the city died, and there was not a single living mouth. And the people killed by cyanide also have calm and serene faces, have weird smiles, and look happy.

Li Zhen's heart moved, could it be that I was thinking too much?

In fact, is the cyanide formula of the Kyushu Academy of Sciences spreading? Someone learned to configure cyanide and used cyanide to kill Wang Tongxue.

So who can afford to configure cyanide?

Li Zhen unconsciously thought of Du Taiping......

Because of the latter two, Li Zhen has never made it out himself, he just knows it.

"Lin Guofu, is Wang Tongxue's face blue?"

Li Zhen asked loudly.
