Standing on the highest mountain in the future base, Cai Ruichen looked at several small towns in the distance that could no longer see their original appearance, and sighed for a while.

The traces of human civilization are gradually disappearing from most corners of the earth, and if it were not for the existence of this place, there are a large number of survivors taking care of the city, between extreme heat and extreme cold, the interior of the city's concrete buildings swells, and the wind blows the seeds of vegetation, carrying dust, and taking root in the city.

The Mozabi County in the future base, the city of Erbil, will inevitably be covered with vegetation, and then time passes, and after a few years, the high-rise buildings in the city that are not maintained and cared for will collapse one after another, and the city will become a ruin under time, and then it will be covered with dense vegetation, withered yellow plants, and falling dust, and finally after a few decades, all the cities will be completely buried.

For those metropolises, they may be able to hold out a little longer, but decades later, they still can't escape the fate of being completely destroyed by historical occasions.

There are not many human beings alive in the world, and according to Cai Ruichen's thoughts, it can really be called a miracle that there are millions of living people now.

It's like these survivors who will be collected by the base in the future, if Cai Ruichen never appeared, and there was no base and Red Police Corps, then most of these survivors would not be able to survive to this day.

Not to mention, it seems that now it is like returning to the era of peace, life has begun to become normal, and life is in order.

But this is only a superficial phenomenon after all, at least in the current environment, it is impossible to have children. Humanity will not hold out much longer than these cities.

When cities disappear, there is no solution to the problem of reproduction. Then humanity will inevitably come to an end.

Let's just say that the current future base, although life is beautiful, the cold winter has lasted for a year, no one is hungry, and no one has been frozen to death.

However, the pressure of survival in the future has not diminished at all in the hearts of most survivors.

Those young kids. It has almost become the only hope for mankind in the future, and the way to change the fate of mankind is not to wait for the rescue of the gods. Rather, it needs to rely on the wisdom that human beings have always endured to survive.

As long as the problem of human reproduction is completely solved, then there will be hope for mankind in the future.

And Cai Ruichen also believes that not only those survivors in his own base, but most of the survivors in the world. They all have the same thoughts.

More than six years of living in the wasteland. Those who have been able to survive until now have mature ideas, and death is really not terrible for most people.

Compared to those who have really suffered, living in the wasteland is more painful than dying a hundred times.

As for whether there is still a large gathering area outside, or human civilization, Cai Ruichen can't say this at present.

But one thing is for sure. Cai Ruichen will never give up all hope, no matter what the outside world is.

For this. He will also rely on the combat laboratory to recruit a large number of experts in the field of biomedicine to be responsible for this aspect.

Among them, Wu Jie, the superhero of the Tyrannosaurus, and Qin Chen, the superhero of the Beast Man, took the lead in researching this issue.

Even if it really involves the need to modify the current genetic genes of human beings, so that the person who conceives will not be disturbed by the virus in the process of fetal embryonic growth, it can only be modified by finding a way.

It's just that if you want to modify the genetics, it is also very, extremely difficult for the technology owned by the base, not to mention that it is even more difficult to formulate the direction of modification.

And this kind of research, with the deepening of research, has also brought about the development of many other medical technologies, and those drugs for the treatment of cancer are also a result of this research project.

It is also appropriate to improve human genes so that they have stronger immunity, which cannot be solved by viruses in the air, and can be used to solve cancer and AIDS.

The research continues, and in Qin Chen's words, even if the research is thirty or fifty years, it must be so that the descendants of the current human race must have the ability to completely immunize the virus in the air.

In fact, among the subjects of the study, Cai Ruichen also contributed his own efforts, because most of the research direction is from his and superhero's serum as a sample.

Qin Chen and Wu Jie were not stingy with their genes and serums, and they all hoped to find a breakthrough from them, the veritable monsters among human beings.

It's just that the virus in the air is completely invisible, and countless viruses are all about the same size and size as God particles.

Under the current technology of human beings, all detection devices cannot fully observe what this virus is.

The most terrifying thing is that these viruses, although they are usually stable, are also quietly evolving and mutating.

As a result, several years of research have been conducted, but the answer to the big question of human reproduction is still zero.

In this regard, Cai Ruichen only hopes that Qin Chen and Wu Jie can go step by step, after all, he still has another earth world.

……

"Commander!"

On the top of the mountain, Cai Ruichen was looking at the sky and the earth in a daze, and Elleyesel came over and woke him up from thousands of thoughts.

"Is Chizuru still in Erbilne?" Cai Ruichen nodded, and asked Elleyesel without looking back.

"Ever since Miss Chizuru came from this world, she has been staying in Erbilene and has not left a single step." Elleyesel said.

"Those mutants under the command of Chizuru, are there any changes?" Regarding Qianhe's actions, Cai Ruichen also felt a little strange.

After returning from Jituyi Island, Chizuru asked to return to the wasteland, and when she returned, she stayed alone in the underground mall in the center of Erbil City.

Cai Ruichen asked the reason many times, but Qianhe just didn't say.

After that, Cai Ruichen did not continue to ask, and at the same time, he also paid attention to Qianhe's whereabouts every day.

In fact, Cai Ruichen also guessed a little, on Ji Tuyi Island, Qianhe's ability was lost, and he fainted, and he recovered immediately after that, but Qianhe's spirit has not been very good.

But as for why such a thing happened to Chizuru, Cai Ruichen didn't know and couldn't understand it.

"Those mutants are very normal, and they eat the mutated creatures we clone every day, most of them have evolved to the first level, and a few have been promoted to two levels." Elleyesel said.

"Continue to pay attention to Chizuru's situation, and report to me anytime if anything." Cai Ruichen commanded.

"Yes." (To be continued.) )
