Lao Yang explained on the stage: "Yes, everyone also guessed that the virus sample created by the fifth-level civilization is a trading chip they proposed. The other party swears so much, it shouldn't be made up randomly, but he really has this thing in his hand. ”

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

Through a virus, it may be possible to decipher more mysteries about life.

Lao Yang continued: "...... This virus can't be said to be completely indiscriminately indiscriminately infected, but many animals on Karina Star have been hit, and the creatures on the same planet always have a great degree of similarity in their genetic material, aren't human genes similar to paramecium? By the same token, most of the creatures on the hemispherical home 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 the two sides cooperate in all aspects, hemispheric civilizations can provide samples of the virus in this area for joint research. ”

A biological sample created by a Level 5 civilization. Several experts specializing in biology looked interested.

The genetic virus from the fifth-level civilization can be regarded as a killer feature of the hemispheric civilization, but the other party did not hide it, but said it directly and transparently, indicating that it had no intention of using it against humans.

This has won the favor of everyone.

Of course, even if the hemisphere secretly uses this virus on humans, humans will not necessarily be tricked. Because under careful preparation, the other party did not obtain the genetic code of the human being. And people are well prepared for defensive measures in this regard.

One of the experts said: "Viruses are dangerous, but they are really valuable for research. As long as the security control is in place, there should be no problem. We are already a fourth-level civilization, and we can study the science and technology left over from the fifth-level civilization, further improve biotechnology, and improve the ability to prevent and control in this area. ”

Zhang Yuan frowned and said, "Don't take it lightly...... I'm wondering, how did hemispheres get infected in the first place? In the face of an unknown virus, are you so careless? ”

"They all already know that the lives of the First Age were killed by the virus, how could this virus be released."

A deputy captain shook his head: "Lao Zhang, do you want to see what era is the story?" Equivalent to our end of the 20th century, beginning of the 21st century! At that time, there were more explorers who died, and the original hemispheric civilization was in a period of archaeological frenzy, and encountered scientific relics, where could there be so many? ”

"Their technology is not developed, can they still wear fully armed spacesuits to explore the North and South Poles? If you want to open the museum, you can open it directly. Moreover, I have serious suspicions that those hemispheres were already infected with mutated viruses when they were digging glaciers. ”

"Okay." Zhang Yuan accepted the statement.

"And then, what about the rest of history?"

"Next, after the resurrection of the alien virus, a terrible plague was naturally born!" Lao Yang saw that everyone in the audience listened very seriously, and he couldn't help but feel a sense of accomplishment as a teacher.

He continued: "...... The original perfect virus was very mild and highly contagious, but it had no overt symptoms, and only destroyed the reproductive cells of life, so that life could not reproduce. ”

"But now it's starting to mutate at a terrifying rate, infecting all kinds of creatures, and a large number of creatures can't reproduce! And this mutation is becoming more and more widespread, various complications appear, and animals and plants begin to die in large numbers. ”

"These complications succeeded in attracting the attention of hemispheric civilizations."

It dawned on them that those damn viruses that had exterminated the multispheres had come back to life for some reason!

And infected them hemispheres as well!

Hemispheric civilization once wanted to control the spread of the virus, but the vast majority of organisms will be infected with this virus, but some symptoms are obvious, some symptoms are not very obvious, these animals flee everywhere, birds fly everywhere, everywhere they go has become an epidemic area, the sea, land, lakes have all appeared plague, how to control it?

As a result, hemispheric civilizations, like multispherical civilizations, have fallen into a more desperate situation......

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

Lao Yang didn't sell it, and directly said the final solution: "The world has entered the apocalyptic mode, the social order has collapsed immediately, and the population is withering rapidly, only some scientists are still working hard." ”

Scientists of hemispheric civilizations in their studies found that their nervous system, not knowing what was going on, was not infected by the virus. These extraterrestrial viruses do not enter the interior of nerve cells to assemble with free nucleotides, which may be related to the membrane structure of nerve cells.

So in order to survive, they made themselves into this kind of bionic model of brain in a jar...... It's weird, but it's still alive. And with the help of the research results of the First Age, the multisphere civilization. ”

"I see! I see! Zhang Yuan let out a long sigh, normal civilization will not make itself like this, but in a desperate situation, in order to survive, there is no way, who let science and technology fail to solve this problem?

The problem of survival is solved for the time being, and then there is the reproduction of species, and there is no way to reproduce with a brain.

The average life expectancy of hemispheric people is about one hundred and twenty years old, although through this model of brain in a vat, the life expectancy has been inexplicably increased a lot, but if there is no next generation, sooner or later it will be extinct.

There are some uninfected germ cells in the biological gene bank, which are well preserved. However, normal life forms will soon be reinfected in this environment full of viruses, so they will eventually become "brains in a jar" to survive......

If the gene pool runs out of germ cells, hemispheric civilizations will still go extinct.

"So, in order to reduce the trouble, the hemisphere has come up with a special cloning technique, which is like 3D organ printing, which can directly 'print' the brain of a newborn! In other words, the newborn baby has no organs except the brain, and it has to use biomimetic organs to survive......"

"You think, since the heart, liver, kidneys and other organs can be cloned with organs...... Then the brain is an organ that theoretically can. ”

Hearing this, a scientist asked: "Hemispheres have such technology?" It's still quite difficult, isn't it? ”

Lao Yang smiled bitterly: "Their biotechnology is just barely passing. Mainly because the multi-spherical civilization of the First Age has been frantically researching this kind of technology, but the multi-spherical civilization has not completely solved it, and it has been directly extinct. It wasn't until the Second Age that hemispheric civilizations perfected these technologies and were barely able to use them. ”

"The culture of applauding when they are happy is probably a legacy of the technology that was so bad at that time."

Someone else asked, "Wait a minute, I have a question." Why don't they create an artificial sterile field to raise normal babies and young children? ”

Yang Fan shook his head: "Your idea is very good, but it is not realistic to actually implement it." At that time, the hemisphere was barely a level 0.9 civilization, and the productivity was not as high as it is now. ”

"To raise the next generation of children, it takes at least millions or even tens of millions of people, and these little children need food and clothing, and have a lot of material needs."

"With the virus all over the world, how big a sterile area do they need to build to meet such a big demand...... The social system has collapsed, and it is no longer possible to be the same as before. ”
