She is the daughter of a residual spirit. She was born with the sound of the blood moon and was called a scourge. He is the incarnation of the spirit of all things. When he was born, the six realms that should have been in turmoil were restored to peace. He was called a dust fairy. Is her encounter with him love? Or debt? She was an immortal in two lives and a devil in one. In her last life, she transcended the six realms and became a person who was neither a demon nor a devil, nor an immortal nor a god. However, the fate of this last life was even more tragic than that of the previous three lives. Because of a misunderstanding, she became a sinner in the six realms. The two people who were supposed to love each other drew their swords at each other, and the two people who were supposed to be together until death were forced to have sex. The two people who should have been happy at the end of the road were separated by life and death. There is no right or wrong in the world, there is only a difference in stance, so she and he are destined not to grow together together until the end of the pain of bone evisceration and heart-wrenching hatred. She is gradually eroded by hatred and becomes a feared devil in the six worlds.
