In the Cangxuan Realm, cultivators can awaken a spirit beast tied to their life force. After being reborn, the protagonist, Chu Yan, carries the memories of his past life as a God Emperor. He discovers that his fiancée, Su Li, is actually the reincarnation of a Nine-Tailed Celestial Fox. To make amends for the debt he left unpaid in his previous life, he awakens a mutated spirit beast, the Heaven-Eater Taotie, which comes with a Chaos Space capable of devouring all things.
