Lao Yang explained on the stage: "Yes, everyone has guessed that the virus sample created by the level 5 civilization is a trading chip they proposed. The other party is so confident that he should not have made it randomly, but that he actually has this thing in his hand."

The Green Star civilization has disappeared, but the scientific and technological heritage of this level 5 civilization is still left in this world, and everyone can't help but increase their attention.

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

Lao Yang continued: "...This virus cannot be said to be completely indiscriminately infected, but many animals on the Kalina Star have been infected. The genetic material of the same planet always has a large degree of similarity. Isn't human genes similar to paramecium? By the same token, most organisms on the hemisphere's parent planet have been infected..."

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

"...If the two sides cooperate in all aspects, hemisphere civilization can provide virus samples in this area and study them together."

Biological samples created by level 5 civilization. Several experts specializing in biology showed their expressions of interest.

The genetic virus originating from the fifth-level civilization can be regarded as a killer weapon of the hemisphere civilization, but the other party did not hide it, but instead spoke it directly and transparently, indicating that it did not have the intention to deal with humans.

This has won everyone's favor.

Of course, even if the hemispheres secretly use this virus on humans, humans may not be affected. Because with careful preparation, the other party did not obtain the human genetic code. Moreover, people are well prepared for this defense measures.

One of the experts said: "Virus is very dangerous, but it is indeed very research-oriented. As long as the safety control is properly controlled, there should be no problem. We are already a Level 4 civilization and can study the science and technology left over from Level 5 civilization, further improve biotechnology, and improve the prevention and control capabilities in this area."

Zhang Yuan frowned and said, "Don't take it lightly... I'm wondering, how was hemisphere infected? Was he so careless when facing an unknown virus?"

"They already know that life in the first era was killed by a virus, so how could it still release this virus?"

A deputy captain shook his head: "Lao Zhang, do you want to see the story of what era it was? It is equivalent to the end of the 20th century and the early 21st century! In that era, there were more explorers who committed suicide. The hemisphere civilization was in the archaeological fanatic period and encountered scientific remains. Where could it be controlled so many?"

"Their technology is not developed. Could it be that they are still wearing full-suited space suits to go to the Arctic and Southern Pole for adventure? If they want to open the museum, they will open it. Moreover, I seriously suspect that those people on the hemisphere were already infected with mutated viruses when they were digging ice."

"Okay." Zhang Yuan accepted this statement.

"And what about the next history?"

"Next, after the alien virus is resurrected, a terrible plague was born naturally!" Lao Yang saw that everyone in the audience was very serious and could not help but feel a sense of accomplishment as a teacher.

He continued: "...The original perfect virus is very mild and highly contagious, but has no obvious symptoms. It will only destroy the reproductive cells of life and prevent life from reproduction."

"But now it began to mutate at a terrifying speed, infecting various creatures, and large quantities of organisms could not reproduce! Moreover, this mutation became more and more widespread, with various complications, and animals and plants began to die in large quantities."

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

Then they suddenly realized that those damn viruses that have exterminated many balls of people have been resurrected.

And they were infected with the hemisphere!

Hemisphere civilization once wanted to control the spread of the virus, but most organisms would be infected with this virus, but some symptoms were obvious, some were not very obvious. These animals fled everywhere, birds flew everywhere, and all the places they went became epidemic areas, oceans, land, and lakes. How to control it?

As a result, hemisphere civilization, like multi-ball civilization, fell into a more superior situation...

This is the first time that their entire civilization has encountered a huge crisis!

Lao Yang didn't keep it a secret and directly said the final solution: "The world entered the doomsday mode, the social order immediately collapsed, and the population quickly withered, and only some scientists were still working hard."

Scientists of hemisphere civilization found in their research that their nervous system, for some reason, was not infected by viruses. These alien viruses cannot enter the nerve cells and use free nucleotides to assemble, which may be related to the membrane structure of the nerve cells.

"So at the end of the road, in order to survive, they turned themselves into this bionic model of brains in the tank... Although it was strange, at least they were alive. And they used the first era and the research results of multi-ball civilization."

"So that's it! I understand!" Zhang Yuan let out a long sigh. A normal civilization would not make him look like this, but in a desperate situation, there is no way to survive. Who can make science and technology fail and cannot solve this problem?

The survival problem has been temporarily solved, and the next step is about the reproduction of species. There is no way to reproduce with one brain alone.

The average lifespan of a hemisphere is about 120 years old. Although the lifespan has been increased by some reason through this model of the brain in the tank, if there is no next generation, it will sooner or later become extinct.

There are some uninfected germ cells in the biological gene bank, which are well preserved. However, normal living organisms will soon be reinfected in this environment full of viruses, so they will eventually become "brain in the tank" to survive...

If the germ cells in the gene bank are used up, hemisphere civilization will still become extinct.

"So, in order to reduce trouble, hemispheres have developed a special cloning technique. This cloning technique is like 3D organ printing, which can directly ‘print’ the brain of a newborn! In other words, newborn babies have no other organs except the brain, and they have to use bionic organs to survive..."

"You think, since the heart, liver, kidney and other organs can be cloned with organs... Then the brain is also theoretically OK."

Hearing this, a scientist asked: "Half-sphere people have such technology? Is this technology quite difficult?"

Lao Yang smiled bitterly: "Their biotechnology was only barely passing the qualifications. It was mainly because the multi-ball civilization in the first era was already crazily studying this type of technology, but the multi-ball civilization did not completely solve it and became extinct. It was not until the second era that the hemisphere civilization improved these technologies and could barely be used."

"The culture where they applauded when they were happy was probably because the technology was too bad at that time, which left behind."

Someone asked again: "Wait a minute, I have a question. Why don't they create an artificial sterile area to cultivate normal infants and toddlers?"

Yang Fan shook his head: "Your idea is very good, but it is not realistic to implement it. The hemisphere talents at that time were barely only at level 0.9 civilization, and their productivity was not as good as we are now."

"It takes at least a population of millions or even tens of millions to raise the next generation of children. These children need to eat and wear and have a lot of material needs."
