The Founder of Diabolism (Seasons 1–3)

Watch The Founder of Diabolism online on iFILM — a 2018 Chinese donghua series in the xianxia fantasy genre, adapted from Mo Xiang Tong Xiu's novel. Wei Wuxian built the Demonic Cultivation path from scratch and paid for it with his life.

He comes back in a stranger's body, memory scrambled, reputation gone. His old rival Lan Wangji — of all people — takes him in rather than finishing the job. Now the two former enemies work through a series of dark supernatural cases, each one trailing back to events neither of them fully understands. Director Xiong Ke paces the story like a slow-burn mystery: answers arrive quietly, the weight accumulates, and the hits land harder for the wait.

Released in 2018, the series helped define what modern xianxia animation could look like. It works even without prior knowledge of the genre — the cases draw you in before the lore does. Stream The Founder of Diabolism (2018) online on iFILM.
