Ji Xiao died four years after the war between the Immortal and Demon realms.
She had once been the person most likely to become an immortal, but she lost her Daoist heart for the sake of a demon. The fearsome woman known as the leader of all demons in the world, Luo Yaomu, was, in Ji Xiao's eyes, simply a woman with a faint smile.
When the war between the Immortal and Demon realms broke out, Ji Xiao had no choice but to kill her with her own hands. From then on, she lost her Daoist heart forever, was devoured by demons, and vanished from the mortal world. Yet when she awoke again, she was a hundred years in the past, reborn before Luo Yaomu had turned to the demonic path, and had become her master.
Looking at the stubborn, cold girl before her, Ji Xiao couldn't connect her to the future Demon Lord at all. And yet this little demon really was ruthless. Ji Xiao thought that for the sake of all living beings, and for her own sake, she would teach Luo Yaomu well. Even if she couldn't become a righteous cultivator of the Immortal Sect, she mustn't become a demon who slaughtered the innocent.
But the little demon, Luo Yaomu, didn't see it that way. She had killed her master with her own hands. So who was this hypocrite? And why was she being so good to her? Fine, then Luo Yaomu would use her to the fullest.
Luo Yaomu called her master at every turn, yet kept taking one step after another down the path to becoming a great demon. With countless sins on her hands and enemies all around, she sneered at this "master," who was determined to lead her onto the righteous path. Until one day, her master used up all her spiritual power to atone for Luo Yaomu's sins and vanished completely.
Luo Yaomu finally panicked, but there was no longer anyone in the world who was determined to teach her to be good.
Ruthless, cold disciple x gentle, devoted master
1v1, happy ending, both take the lead
Theme: What goes around comes around; always keep a compassionate heart
