Three thousand years after the great cataclysm, the earth was reduced to a "ruin realm" and humans degenerated into tribal nomads. In the night sky, satellite debris forms a "star chain", which is regarded as a miracle, but it also conceals a harbinger of destruction. Young Jialuo, the only "Shepherd" in the tribe who can sense the changes in the Star Chain, is forced to embark on an epic journey to find the legendary "Ark" due to the crisis of the Star Chain's fall.
