Li Yu, the young master of the Bright Realm of the Ten Realms was kidnapped. Because he had the way of space, he was used as a sacrifice to open up the Nine Heavens. He kept getting smaller in the reverse river of time. By coincidence, he opened the space cracks and traveled to the earth, which also brought unimaginable changes to the earth. Human beings began to die in large numbers, and the shadow of death continued to envelope humans. Mutated beasts and magical plants began the feast of doomsday. After turning back into Doudin, he kept getting stronger in order to go home, rushed out of the galaxy, and wandered through the stars with his gay friends.
