The heroine, Yue Xiner, is actually a princess of the Celestial Realm, the daughter of the Celestial Emperor and the eldest princess of the Demon Realm. When the Myriad Manifestation Order suddenly appeared, the Celestial Empress, who was also the eldest princess of the Demon Realm, was falsely accused of harboring sinister ambitions and secretly grooming the next Demon Emperor. She then took her own life. After losing her mother, the heroine hid her identity from childhood on the orders of her imperial father and became the first female High God in the Celestial Realm. Later, after an accident sent her to the mortal world to undergo trials for ten years, she returned to the Celestial Realm and fell in love with Feng Hanli. Along with finding love, she discovered that she was the one who controlled the Myriad Manifestation Order. She unified the Demon Realm, cleared her mother's name, and exposed the corruption behind the Celestial Realm's so-called justice.
