Chapter 698

Lao Yang explained on the stage: "yes, as you guessed, the virus samples created by the five civilizations are a trading chip they put forward. The other party's vows should not be made up, but they really have this thing in their hands. "

The green star civilization has disappeared, but the scientific and technological heritage of this five-level civilization remains in the world, and everyone can't help raising their attention.

Through a virus, we may be able to solve more mysteries about life.

Lao Yang continued: "... This virus can not be said to be completely indiscriminate infection, but many animals on Kalina have been recruited. The genetic materials of organisms on the same planet are always similar to each other. Aren't human genes similar to Paramecium? In the same way, most of the creatures in the hemisphere mother planet are infected... "

"But this virus may not be able to infect humans, because the species on two different planets are still very different."

"... if both sides cooperate in an all-round way, hemispheric civilization can provide virus samples in this regard for joint research."

Biological samples created by five civilizations. Several experts specializing in biology showed interest.

Genetic viruses derived from the five levels of civilization can be regarded as a killer mace of hemispheric civilization, but the other party did not hide it, but directly and transparently said it, indicating that it did not use it to deal with human beings.

This has won everyone's favor.

Of course, even if people in the hemisphere secretly use this virus on humans, humans may not be caught. Because with careful preparation, the other party did not get the human genetic code. And people are well prepared for defensive measures in this regard.

One of the experts said: "the virus is very dangerous, but it is of great research value. As long as the security is properly controlled, there should be no problem. We are already a fourth level civilization. We can study the science and technology left over from the fifth level civilization, further improve biotechnology and improve the prevention and control ability in this regard. "

Zhang Yuan frowned and said, "don't take it lightly... I was thinking, how did people in the hemisphere get infected? Are you so careless in the face of an unknown virus? "

"They all know that life in the first era was killed by a virus. How can this virus be released?"

A vice captain shook his head and said, "Lao Zhang, do you want to see the story of what age it is? Equivalent to our end of the 20th century, the beginning of the 21st century! At that time, there were many dead explorers. The original hemispheric civilization was in the period of archaeological fanaticism. When it met scientific relics, where could it manage so much? "

"Their science and technology are not developed. Can't they still go to the north and south poles in fully armed spacesuits? If you want to open the museum, you can open it directly. Moreover, I seriously doubt that those people in the hemisphere were infected with the mutated virus when they were digging glaciers. "

"All right." Zhang Yuan accepted this statement.

"Then, what about the next history?"

"Next, after the resurrection of the alien virus, a terrible plague was born naturally!" Lao Yang saw that everyone under the stage listened very carefully. He couldn't help feeling a sense of achievement as a teacher.

He continued: "the original perfect virus is very mild and highly infectious, but it has no dominant symptoms. It will only destroy the reproductive cells of life and make life unable to reproduce."

"But now it begins to mutate at a terrible speed, infecting all kinds of creatures, and a large number of creatures can't reproduce! Moreover, this variation is becoming more and more widespread, with various complications, and animals and plants begin to die in large quantities. "

"These complications have successfully attracted the attention of hemispheric civilization."

They suddenly realized that those damn viruses that killed many people in the world had come back to life!

And infected them all!

Hemispheric civilization once wanted to control the spread of the virus, but the vast majority of organisms will be infected with the virus, but some symptoms are obvious, some symptoms are not obvious, these animals flee everywhere, birds fly everywhere, all places they go have become epidemic areas, and plagues have appeared in oceans, land and lakes. How to control them?

As a result, hemispheric civilization, like multi global civilization, fell into a desperate situation

This is the first time that their whole civilization has encountered a great crisis!

Lao Yang did not sell off, but directly said the final solution: "the world has entered the doomsday mode, the social order has collapsed immediately, and the population has withered rapidly. Only some scientists are still working hard."

Scientists of hemispheric civilization found in their research that their nervous system did not know what was going on and was not infected by virus. These alien viruses can not enter the nerve cells and assemble with free nucleotides, which may be related to the membrane structure of nerve cells.

"So at the end of the mountain, in order to survive, they made themselves into this bionic model of brain in a jar... It's strange, but at least they live. And with the help of the research results of the first era and multi global civilization. "

"I see! I see! " Zhang Yuan breathed a long sigh. Normal civilization would not make itself like this, but there is no way to survive in a desperate situation. Who can't solve this problem if science and technology fail?

The problem of survival has been solved temporarily, and then there is the reproduction of species. There is no way to reproduce with a brain alone.

The average life expectancy of people in the hemisphere is about 120 years old. Although this model of brain in a jar has inexplicably increased their life expectancy, if there is no next generation, they will be extinct sooner or later.

There are some uninfected germ cells in the biological gene bank, which are well preserved. But normal life will soon be reinfected in this environment full of viruses, so it will eventually become a "brain in a VAT" to live

If the germ cells in the gene bank run out, the hemispheric civilization will still die out.

"Therefore, in order to reduce the trouble, the hemispheric people have developed a special cloning technique, which can directly 'print out' the newborn's brain like 3D organ printing! In other words, the newly born baby has no other organs except the brain, so it has to use bionic organs to survive... "

"You think, since the heart, liver, kidney and other organs can be cloned with organs... The brain is also possible in theory."

Hearing this, a scientist asked, "do people in the hemisphere have such technology? This technology is still very difficult, isn't it? "

Lao Yang said with a wry smile, "their biotechnology is just barely passed. Mainly because the multi sphere civilization in the first era has been frantically studying this kind of technology, but the multi sphere civilization has not completely solved it, so it has directly become extinct. It was not until the second era that hemispheric civilization perfected these technologies that they could barely be used. "

"The culture of clapping as soon as they are happy is probably left over because the technology was too bad at that time."

Another person asked, "wait a minute, I have a question. Why don't they create an artificial sterile area to cultivate normal infants and young children? "

Yang Fan shook his head: "your idea is very good, but it's not realistic to really implement it. At that time, the hemispheric talents were barely level 0.9 civilization, and the productivity was not like what we are now. "

"Raising the children of the next generation requires at least millions or even tens of millions of people. These children have a lot of material needs to eat and wear."

"When the outside world is full of viruses, how large aseptic area do they need to build to meet such a great demand... The social system has collapsed, and it can no longer be like before."
