Lu Xiao, who transmigrated into this world, was tricked by an empty promise into infiltrating the Demonic Sect as an undercover agent. Three years, they said—but he ended up staying for nine. The system wants him to become the strongest evil cultivator, so he chooses the easiest solution: kill all the other evil cultivators, and wouldn't that make him the strongest? He continues his undercover mission in the Demonic Sect, betraying his fellow cultivators, looting corpses, collecting souls, and refining puppets after every kill. He throws the evil cultivators into turmoil while leaving the righteous sects utterly bewildered. Even his self-proclaimed title, 'Heaven-Swaying Demon Venerable,' gets passed along until it becomes 'Demon-Subduing Heavenly Venerable.' After finally killing the Blood Fiend Old Demon, he becomes Qingzhou's number-one evil cultivator. Yet the righteous cultivators behind him unanimously hail him as the 'Leader of the Righteous Path.' Lu Xiao, I really am an evil cultivator!
