Shen Qingyan, an unambitious sweeper at a Taoist temple, accidentally discovers Su Jiuli, the ten-thousand-year-old fox demon empress, bathing in a hidden realm. Drawn to his one-of-a-kind, utterly pure destiny and his immortal aura and blood, the empress forcibly claims him for herself. Imprisoned against his will and reduced to her exclusive source of spiritual power, he fights the schemes of the male favorites in the demon palace, breaks free of the shackles of fate, and reverses his destined transformation into a demon. In the end, he rises from a lowly mortal to godhood, making the fox empress, obsessed for a thousand years, bow to love. Together, they rewrite the fate that says humans and demons can never be together.
