He Yu is an ordinary young man struggling at the bottom of the urban world. Framed by his superior and betrayed by his girlfriend, he is buried in debt. In despair, he falls from a rooftop. Yet his body does not die. Instead, it is taken over by the soul of Lin Potian, the last Martial Sovereign from a world of advanced martial arts. A legend in the martial world, Lin Potian had been betrayed by the woman he loved and his sworn brother, leaving him dead and his spirit shattered. A wisp of his remnant soul crossed through time and possessed this young man, who had also been abandoned by fate.
With He Yu's memories fused with Lin Potian's soul, the new He Yu awakens in a hospital bed. He inherits Lin Potian's Hunyuan Martial Scripture, a cultivation method powerful enough to found a martial arts school, along with his extraordinary martial knowledge and the ruthless resolve of a strongman. But he finds himself in a modern city where spiritual energy is scarce and martial arts have fallen into decline. The mess left behind by the original He Yu is appalling: a 500,000-yuan loan shark debt is about to come due, the company supervisor who framed him is waiting to laugh at him, and the insults from his ex-girlfriend and her new boyfriend still ring in his ears. What concerns Lin Potian even more is a hazy fixation buried deep in He Yu's memories: a girl named Su Wanqing. She was the only light in He Yu's bleak childhood, and one of the reasons he fought so hard to stay alive.
