The Founder of Diabolism (2018)

As the grand-master who founded the Demonic Sect, Wei Wuxian roamed the world in his wanton ways, hated by millions for the chaos he created. In the end, he was back-stabbed by his dearest shidi and killed by powerful clans that combined to overpower him. He incarnates into the body of a lunatic who was abandoned by his clan and is later, unwillingly, taken away by a famous cultivator among the clans-Lan Wangji, his archenemy. This marks the start of a thrilling yet hilarious journey of attacking monsters, solving mysteries, and raising children. From the mutual flirtation along the way, Wei Wuxian slowly realizes that Lan Wangji, a seemingly haughty and indifferent poker-face, holds more feelings for Wei Wuxian than he is letting on.
