In 2020, biologists from Country A announced that the preliminary experiments of the "Natural Selection Project" were successful, and that the fate of mankind will be determined by the "Natural Selection" virus-the virus has a 30% probability of inducing atavistic gene mutations in humans, thereby triggering biological degeneration. In other words, 30 percent of humans will degenerate into "other animals" to repay humanity's debt to nature.
The resulting survival problems, humanitarian crises, social unrest, and wars... Until the era of natural selection in 2220, the aftermath still has not subsided.
Two hundred years later, the young scholar Ding Shi, the culprit of the "Natural Selection Project", woke up from his hibernation chamber. He was the last biologist in the world.
Note: Two hundred years ago, the gloomy, sick, weak and aggressive x sunny, cheerful and feeling relationship may have changed two hundred years later.
