I’ve returned from a million years ago

One day in the year 2222, a large spaceship from a prehistoric civilization from a million years ago stopped in the sky above Earth!

In order to defend against the enemies in outer space! The owner of the spaceship, Zhao Xiaofeng, the mentor of humanity, led the heroes of Earth to explore the prehistoric civilization!

The legendary witch race, the Heavenly Court, God, Satan, Amon, and other gods actually existed in Earth’s history!

The powerful civilizations that had appeared on Earth were destroyed by history one after another!

Humans had discovered these high-tech bases left behind by the prehistoric civilization! Reorganizing the Earth Federation!

Earth’s hopeless fate finally had a chance!

[Important note: This novel is hard science fiction, no system!] The setting was rigorous, the idea was ingenious, and the author’s character was guaranteed. It was not frivolous or eunuch!

I plan to write five books about human exploration of the universe in different technological periods!
