Ling Yue possesses extraordinary talent, yet she is framed by her junior sister for stealing a priceless treasure and is condemned by the entire sect overnight. Unwilling to yield even in the face of death, she refuses to undergo a soul-searching examination to prove her innocence. Instead, she strikes a contract partnership with Yan Xuanjin, the young master of an immensely wealthy family in the Immortal Realm. While everyone waits to see her humiliated, she turns the tables on her enemies, crushes those who once wronged her, and steadily ascends to become the Immortal Emperor. Only after achieving greatness does she discover that her cold-faced husband is actually the boy who would become the Demon Emperor, whom she rescued as a child amid a sea of blood and corpses. He exists because of her, and she stands strong because of him. Crossing the divide between immortals and demons, they save each other and join hands to establish a new order for the Three Realms.
