You Jin travels back in time to the villain heroine in a fairy tale novel, and her mission is to conquer the demon king Ling Gui.
A few days later, she discovered that she was poisoned and was about to die soon. The key to detoxifying the poison was the Demon Lord, so she had sex with the Demon Lord Ling Gui the next day and ran away.
The Demon Lord disturbed the peace of the six realms just to find You Jin.
A few months later, Demon Lord found You Jin and asked, "Who are you? You dare to climb into my bed. Forget it, you have made me pregnant."
You Jin was dumbfounded when he saw the big-bellied Demon Lord in front of him.
Mission: There is no boundary between good and evil
