Yin Nian, the illegitimate daughter of the Beast Kingdom, awakens the Phoenix Beast Origin. Yet the Empress and her daughter gouge out her bones to seize her origin and cast her into the Abyssal Demon Gorge. On the brink of death, she is taken as an adopted daughter by Yin Nü, an ancient great demon. Cultivating both spirit and demonic power, she bursts forth with divine beasts to seek vengeance. Using a Soul-Replacement Pill, she disguises herself as Bai Bailu, sowing chaos within the royal family of the Beast Kingdom. She then travels to Shengshan Sect to find a way to break the seal. In the end, she shatters the seal to rescue her mother. Together with her beloved Yuan Xinsui and Yin Nü, she swears to bring down the hidden mastermind, the Floating God Tower.
