Feng Lian, the legitimate princess of the Phoenix Clan, descends to the mortal realm to undergo a trial of tribulation, only to be cruelly deceived by her husband, Jiang Huaiqing, who pretends to die. As he ascends and transforms into a dragon, he heartlessly takes her life. Reborn overnight, she returns to the eve of Jiang Huaiqing's ascension and specially forges close-fitting armor from refined iron to foil his scheme of transforming into a dragon while naked. She unexpectedly takes in Xiaobai, a white fox who seems to be faking an injury to gain sympathy, but who is actually Xie Wang, the Fox Venerable who reversed time for her. In this life, Feng Lian tears apart the sweet-faced schemers, humiliates her wicked relatives, exposes the impostor hiding behind a false identity in the Heavenly Realm, battles formidable enemies in the Demon Domain, and rises to the pinnacle to become the supreme ruler of the Heavenly Realm.
