Wei Wuxian is alive, when he was thrown in the burial mounds thats where he got his dark cultivation magic in controling corpse's or dead people. And thats what he used in defeating the Wen-clan... But after time using it the outher cultivating clans started to be anxious around him and he also used that power in making Wenning his own loyal servant when Wenning died from hard abuse fron the Jin-clan, and that also caused the death of Jiang cheng's older sister and her husband (it was an accident because of Wenning being out of control) and when jiang cheng had his army attack wei wuxian that power Wei wuxian has also back fired which is also the cause of his first death.(the dead ate his flesh) (=・ω・=)
