The white fox demon emperor Jiu Yuan set a love calamity for three lifetimes with Mo Yuan, the prince of the immortal world, in order to save his people. In the first life, she exchanged her life for him to prove his truth, but he personally cut out her heart and proved his ruthlessness; in the second life, she was reincarnated as a mortal emperor, and he held her in the palm of his hand as an immortal king, forcing her to kill him with her own hands to prove his love; in the third life, she turned into a world-destroying demon, and he knelt down and begged her for forgiveness as an immortal emperor. After three lifetimes of entanglement, and when his soul was shattered, he realized that the ten thousand-year demon pill sealed in her body was the only key to him overcoming the tribulation and becoming a god.
