After the God King Tang ascended to the divine realm, Qian Renxue of the Spirit Master Continent was caught in a struggle among the various factions and chose to self-destruct. Her soul was later saved from the God King Tang by the God of Death, a suitor of the Angel God, and traded to Bai Wuchang.
Later, when Sun Wukong wreaked havoc in the underworld, one of his hairs carried Qian Renxue past Meng Po's soup and straight into reincarnation.
From then on, with Sun Wukong's hair as her aid, Qian Renxue began a journey across the myriad worlds.
