A junior disciple of the Gusu Lan Sect. Born Wen Yuan, he's the last remaining blood descendant of the now-extinct Qishan Wen Sect. He was one of the Wen clan remnants taken in by Wei Wuxian shortly before his death, but he lost his home for a second time in the first siege of the Burial Mounds.

Discovered by an injured Lan Wangji who came searching for Wei Wuxian's remains in the aftermath, the then-three-year-old boy fell into a high fever and lost all memories of his past. He was then re-named to Lan Yuan and later presumably given the courtesy name Sizhui in the same year that Wei Wuxian returned to the living world.

The Wen Clan's rampage caused untold sufferings, and the other cultivation clans launched the "Sunshot Campaign" to join forces against the Wen Clan. Although Wei Wuxian, the Yiling Patriarch, had made great contributions to overthrowing the Wens, he was stigmatized and punished because he was considered too powerful and dangerous. He was persecuted by ten thousand people.
 
Thirteen years later, Wei Wuxian has been brought back by a sacrificial ritual and has met again with old acquaintances such as Lan Wangji from the Gusu Lan Clan and Jiang Cheng from the Yunmeng Jiang Clan. The mysteries of Wei Wuxian's past remain, and conflicts in the cultivation world have resurfaced - all of which began from when they were all once youths.

Continuing his masquerade as the deranged lunatic from the Lanling Jin Clan, Wei Wuxian resides in the Cloud Recesses while his former cultivation classmate, Lan Wangji, searches for answers about the demonic severed arm they have in custody. With an overwhelming dark energy emanating from the arm, the two are forced to work together in order to keep it contained. However, the demonic arm is not the only dark force lurking in the region, and as spiritual tensions rise in the mountains of the Gusu Lan Clan, it is up to the two of them to try and restore the natural order. 
 
The story of Wei Wuxian's fall from grace continues as more light is shed on his descent into the path of demonic cultivation. The demonic arm only further strains his mischievous spirit. This is the time for him to prove that he has truly broken free from the forbidden path and is not the maniacal sorcerer that everyone remembers him to be.

Feared and hated for his sinister abilities, Wei Wuxian–the grandmaster of demonic cultivation–was driven to his death when the most powerful clans united to destroy him. 
 
Thirteen years later, Wei Wuxian is reborn. Summoned by a young man who sacrificed his soul in a forbidden ritual, Wei Wuxian is now bound to seek vengeance on the stranger’s behalf or risk the destruction of his own soul. But when an evil entity emerges, a familiar face from Wei Wuxian’s past suddenly appears amidst the chaos–Lan Wangji, a powerful cultivator who will help shine a light on the dark truths that surround them.

This series hopes to heal the audience who loves the main story of Mo Dao Zu Shi, but were “injured” by the melancholy plot of the drama.
