Studies have shown that before the advent of human civilization, there may have been a high level of civilization of other species on Earth.

As we all know, many monuments of civilization do not belong to us humans. In fact, there are many monuments of civilization that we humans cannot build with today's high technology.

Based on these speculations, some scholars have put forward the theory of prehistoric civilizations.

In 1998, in the Egyptian pyramids, archaeologists discovered an artificial heart from the left breast of a boy mummified, which was inserted into a boy's chest 5,000 years ago. This fact strengthens the claim of prehistoric civilization.

What's even more shocking is that in 2018, scientists dug up a liquid nitrogen tank in Zhoukoudian, Beijing.

In this tank of liquid nitrogen are five hearts, five hearts that are very similar to humans, but it is certain that they are not human hearts.

Of course, there are also inferences that this may be an incompletely evolved heart.

With the progress of science and civilization, human beings have become more and more eager for eternal life, so the "cryonics technology" was born. As the name suggests, scientists freeze the human body with liquid nitrogen and then store it in a tank of liquid nitrogen. Theoretically, one day in the future, in the future when science and technology are more advanced, it is possible that these frozen people will be "resurrected".

But the problem is that the liquid nitrogen tank dug up in Zhoukoudian has existed for at least 3,000 years.

As soon as this news was reported, global public opinion was in an uproar.

......

After the liquid nitrogen tank was opened, the five hearts stored in it quickly thawed, but no one expected that these thawed hearts would begin to decay.

The Beijing Cryonics Center was ordered to receive the five hearts in a hurry, but unfortunately only four of them were saved in the end, and the other one was completely necrotic.

The cryocenter refreezes the 3,000-year-old hearts.

However, for unknown reasons, the refrozen heart continues to fail, but the rate of decay is greatly slowed.

The state department urgently set up a special research team and appointed Professor Han Yi as the team leader.

Professor Han Yi lived up to his responsibilities and led the researchers to study various problems day and night, and came to a conclusion in the shortest possible time: these ancient hearts have the possibility of survival in the human body.

This is good news, of course, but there are pros and cons.

The data shows that these ancient hearts have strong pulsations, and the human body is likely to be unable to withstand them.

In view of the fact that the refrozen hearts continue to decay, Professor Han Yi came up with a crazy idea: instead of putting these hearts in a liquid nitrogen tank and slowly disappearing, it is better to take this opportunity to try it boldly.

Fit them into human bodies!

There is also a debate within the special research group about Professor Han Yi's idea.

It has been suggested that this would be a breakthrough study that could have a significant impact on the study of prehistoric civilizations.

Some people think that this may create a bunch of monsters, which is against human morality.

However, there is one consensus among all: this should be the only way to preserve the Ancient Heart at this stage.

Since they can't be cryopreserved, let them go into the vector and be reborn.

Professor Han Yi's bold idea was approved by the relevant state departments, but the approval letter for this project was not carried out in the normal process, but was supervised by the National Office for Special Events, and every participating researcher must sign a confidentiality agreement.

As soon as the project was approved, work began expeditiously.

Since this project requires a carrier, the first step is to focus on the carrier.

The so-called carriers are actually people, living human beings.

How to choose, and who to choose to experiment? After all, these experiments are very risky, and whoever becomes the carrier may not survive.

The National Office for Special Events has issued instructions for this purpose: to select carriers from the army, volunteers are preferred, fatherless and motherless are preferred, and young and strong are preferred.

When recruiting carriers, the routine announcement emphasized the arduousness of this task: a secret mission, sacrificing one's life for the country, and dying for one's life.

......

Despite the almost cold writing in the public notice, the recruitment of carriers went very smoothly.

There are countless patriotic young people, how can there be people who are greedy for life and afraid of death?

Even if he is in the army, who is not full of enthusiasm? Who has not had the heroic pride of the horse leather shroud?

However, some things are more brutal than imagined.

The first batch of carriers, a full 16 people, 16 hot-blooded young people, none of them survived.

That night, Professor Han Yi couldn't sleep.

He felt like an executioner and killed the 16 young men with his own hands.

The 16 patriotic young people who ran away from the orphanage were just gone, and even because they had no family members, they could not even pay their pensions.

In the past, Professor Han Yi was a healer who saved lives, but today, he feels like a butcher.

A man with iron bones, lying on the operating table as if he was dead, what courage and courage he was, and none of them survived.

The pulse of the ancient heart was beyond anyone's imagination, and after entering the human body, each beat was fatal.

It is true that these hearts can survive in the human body, but the problem is that no body can withstand such intense stress.

The heart is like a compressor, and if the compressive force of the human heart is compared to 1, then the compressive force of these ancient hearts reaches a terrifying 10.

10 times the pressure, no human body can withstand it.

Under such pressure, the internal organs become congested and the blood vessels burst.

Professor Han Yi leaned on the railing, his face tired.

No one knows the pain in his heart, but he still has to lead this group of researchers to move forward, which means that maybe more people will die at his hands.

The mission given by the country, even if he gives up his old life, he will have to get a result.

However, all 16 vector tests failed, which seriously affected the progress of the project.

Zhou Yirong looked at the majestic and lonely figure in the corridor, a little hesitant, not knowing whether to say some words or not.

All 16 people died, and everyone in the research team was in a heavy mood.

Professor Han Yi heard some movement, turned his head to look at Zhou Yirong, and asked, "Why don't you sleep yet?" ”

Zhou Yirong hesitated, but still spoke: "Teacher, I think we should continue the carrier test......

Professor Han Yi frowned and asked rhetorically, "Didn't you take the lead in opposing it at the beginning?"

Zhou Yirong said: "Either you don't start, since you have started, you can't stop." ”

"You also know the current situation, and if you continue to try like this, you will only continue to die. ”

"I know...... It's just, I want to ...... You've probably thought about it, and there's a category of people who might be able to afford it......"

Professor Han Yi was silent.

Zhou Yirong continued: "The astronaut's physique can withstand more than ten times the normal pressure when the rocket is lifted off, I want to ......"

Syllable......

Professor Han Yi lit a cigarette.

Cosmonaut!

It's easy to say, but how many astronauts can a country have?

As far as Huaxia is concerned, after so many years of non-stop training of newcomers, the number of people has only remained at about 20.

One out of ten thousand, is the pilot.

And the pilot will go through one thousand selections before he becomes an astronaut!

The next day, Professor Han Yi typed an application report: apply for astronauts to participate in this carrier test.

The progress of mankind has been accompanied by the sacrifice of countless people, but people will not stop moving forward because of this, even if every step will come at a terrible price.

Some studies are not known to be fruitful, but in the 21st century, people clearly understand that only by moving forward can they become stronger.

......

At the same time that the special scientific research team was carrying out research tasks day and night, a major incident occurred in the capital.

An unknown virus spread quickly.

But anyone who is infected, whether male or female, old or young, will grow hard scales on their skin, and it feels like a bestiality in a movie.

Beijing is a world-class metropolis with a high population density and high mobility, which provides great convenience for the spread of the virus.

At first, there were only two or three cases of clinical symptoms, which did not attract attention.

It's just that what people didn't expect was that in just three or five days, the number of clinical cases changed from two or three hundred to two or three hundred, and this number is still increasing exponentially, and the speed is comparable to SARS back then!
