On an abandoned road in the countryside, Wei Wuxian and Lan Wangji come across a stone plaque with the inscription “Yi City”. In their quest to uncover the mystery behind the cursed severed arm, they venture into the abandoned city in search of new leads.

However, their investigation takes a dangerous turn with the arrival of a mysterious cultivator, leading Wei Wuxian and Lan Wangji to a plot that could threaten the entire cultivation world. The situation becomes even more critical when they discover that the Chief Cultivator of the renowned Lanling Jin Sect, Jin Guangyao, is involved.

As Wei Wuxian and Lan Wangji delve deeper into the conspiracies of the cultivation world, their friends and allies begin to question their motives. With the world turning against him, Wei Wuxian must clear his name and prove he is not the demonic sorcerer people believe him to be. He must regain their trust and stop the sinister evil from destroying the cultivation world.

Posing as a crazed member of the Lanling Jin Clan, Wei Wuxian takes refuge in the Cloud Recesses while his former cultivation classmate, Lan Wangji, investigates the mysterious demonic arm in their possession. With its dark energy radiating ominously, the two are compelled to work together to contain it. However, the demonic arm is not the only dark presence in the area and as spiritual unrest grows in the Gusu Lan Clan’s mountains, Wei Wuxian and Lan Wangji must strive to restore balance.

The tale of Wei Wuxian’s fall from grace continues as more is revealed about his journey down the path of demonic cultivation. The demonic arm only intensifies his mischievous spirit, making this the time for Wei Wuxian to demonstrate that he has truly forsaken the forbidden path and is no longer the maniacal sorcerer that he once was.
