Reborn 1990 Little Doctor

Chapter 2268 Years (finale)

Following this line of thought, scientists will soon extract special enzymes.

At the beginning, scientists made this enzyme into a drug and let people take it. It turned out that the human body's ability to adapt to harsh environments has improved, but with the metabolism of the drug, this ability to adapt getting weaker and weaker.

Since it cannot be taken externally, it can only be combined in the human body, so scientists are moving towards another research idea. They fuse the fragment of this enzyme to the human gene.

This fusion process took a lot of effort, and finally the research failed.

By this time, scientists also realized that it was too difficult to change species.

The only remaining human beings put all their energy into changing the environment and optimizing the environment. As plants that can adapt to underground life, people planted a large number of rejuvenating plants. After a long period of time, the environment was finally improved to a limited extent.

Rejuvenation can emit oxygen through the soil, which makes the environment on the ground less harsh.

After such a long time, the original vegetation on the ground never grew again.

What now covers the ground is a plant similar to thorns and moss. This plant does not have as much nutrient content as rejuvenation, but it can also perform photosynthesis and spit out a small amount of oxygen.

And the species in the ocean have also changed. A large number of precious and delicate deep-sea fish died one after another because they could not stand the polluted environment. Amphibians occupied the water source. This new species evolved quickly and was named by scientists as the salamander.

At present, the lizard salamander is highly suspected to have intelligence, and it seems to have the posture of occupying the sea resources and fighting against human beings.

Now humans are not as proud as they used to be.After a long underground life, everyone also realized that if we continue to blindly consume resources, human beings will become extinct sooner or later.

Newborn animals and plants have a strong ability to adapt to the environment, but human beings are as fragile and delicate as newborns. In some places with low oxygen content, they have to wear helmets to live.

In any case, people have finally returned to the ground, and everyone cherishes their current life.

Although the earth's resources have been consumed too much, the sun can still shine for many more years. If human life is not to die, then maybe we can persist until the return of the explorer, bringing everyone the hope of immigrating to a new planet.

Human beings returned to the ground, and the original order remained unchanged. After so many years of development, Su Nian and Chu Beichen's Nianchen Group has grown unprecedentedly, and some people have asked them to come forward to participate in management, but neither of them is interested in government affairs.

Now that the husband and wife are quite old, they just want to improve their living and living environment within their own capabilities.

It has been ten years since Chu Yongkang and Aya left on the Explorer. At the beginning, the Explorer could send back messages regularly to report the itinerary and new discoveries to Earth, but three years ago, the Explorer suddenly lost the news.

I don't know if there was an accident on the Explorer, or if the news couldn't be sent back in time.

For this reason, Su Nian and Chu Beichen have been very anxious, no matter what, Chu Yongkang is their child, as long as the husband and wife are alive, they are willing to wait for Chu Yongkang to come back.

The only good thing is that after going through the difficult years of the dungeon, human immunity and survivability have been greatly improved compared to before. Although it has not reached the level of the lizard salamander, it is much stronger than before.

Hope it is not extinct after all.
