At the beginning of the century, there was a black planet Staner floating in space. Ling Shuang was the first warrior of Staner Planet. When Bart, the commander-in-chief of Staner Planet, discovered the earth and decided to invade the earth, he sent Ling Shuang to the earth to investigate. Ling Shuang was infected by earthly things on the earth, changed from an invader to a defender, and stopped the invasion. Until today, 2000 years later, Bart invaded the earth again. Ling Shuang's body was destroyed by Bart. Ling Shuang's consciousness came to the earth and found Tianhai, a descendant of the earth warrior who fought with him 2000 years ago. He took him back to 2000 to practice, helped him step by step to become a strong man, and completely crushed Bart.
