Earth in 3010

A million years ago, a highly advanced civilization on an ancient star searched the universe for a suitable new home. They came to Earth and chose apes as hosts, implanting their genes of intelligence into their brains to achieve a different kind of migration to Earth. But after finding a more suitable planet to settle on, they hurriedly left Earth.

In 2010, they came to Earth again.

"When we terminated the plan, we forgot a dying female ape. She didn't die. She gave rise to the terrifying human race, which possesses some of our genes of intelligence while retaining the savage cruelty of animals. Intelligence isn't helping humans live better lives. It's merely a weapon that lets them slaughter one another, upgraded from sharpened branches to nuclear weapons. What's terrifying is that they won't just slaughter one another until Earth is destroyed. They'll also venture into space and go on to destroy other planets, upsetting the balance of the universe. We must conduct an experiment. Whether humanity should be eliminated will depend on its results."

Chen Weike, a kind, naive, and melancholy young woman. Ray Collison, an outstanding American fighter pilot.

In 2060, Ace returned to Earth.

"Ace, you are the first purely intellectual being on Earth. Remember, this is humanity's last chance!"

By 3010, Earth had become a truly unified whole!
