Seventy thousand years later, Bai Qian attempts to also sacrifice herself to re-seal the demon lord but is instead thrown to the mortal realm where she loses all her memories and divine power. Living alone on a remote mountain, Bai Qian saves Crown Prince Ye Hua of the Nine Heavens, who is actually her fiancé in Heaven and greatly resembles the late Mo Yuan.
