Ling Chen is a "waste" who can be bullied by everyone in the martial arts school. No one knows that he is a top killer hiding in the dark, and he is also an evil undercover who has sneaked into the righteous way. He lay dormant and waited for the opportunity to show off. In a crisis, he was forced to reveal part of his strength in order to save the miserable but stubborn Su Qingyuan, and he broke away from the "waste" disguise. With showdowns one after another, his identity gradually surfaced. The righteous were afraid of him and the evil was attracted by him. The relationship between him and Su Qingyuan grew in the gap between good and evil. When Su Qingyuan learned of his undercover identity, the two were in a dilemma. Faced with the pursuit of the right and the use of the evil, Ling Chen swept across the world with both good and evil means. He not only wanted to protect Su Qingyuan, but also wanted to carve out his own world in the world of high martial arts, and eventually became a big threat that neither the good nor the evil dared to provoke.
