As the grandmaster who founded the Demonic Sect, Wei WuXian roamed the world in his wanton ways, hated by millions for the chaos he created. In the end, he was back-stabbed by his dearest shidi and killed by powerful clans that combined to overpower him. He incarnates into the body of a lunatic who was abandoned by his clan and is later, unwillingly, taken away by a famous cultivator among the clans—Lan WangJi, his archenemy.
