The Founder of Diabolism - S01

Still posing as the madman from the Lanling Jin Clan, Wei Wuxian stays in the Cloud Recesses while Lan Wangji, his old cultivation classmate, investigates the origins of the demonic severed arm in their possession. The arm's intense dark energy forces them to cooperate to keep it under control. But other sinister forces are at work in the region, and as unrest grows among the spirits in the Gusu Lan Clan's mountains, the two must work to restore balance. Wei Wuxian's past continues to unravel, revealing more about his turn to demonic cultivation. The cursed arm tests his already rebellious nature, challenging him to prove he has truly abandoned the forbidden path-that he isn't the dangerous sorcerer people once feared.
