Su Wanning, who died suddenly while working overtime, woke up and found that she had been transported into a fairy tale and became the villainous female supporting character with the worst fate in the book - three days later, she will be forced to defend the male and female protagonists from the catastrophe, and her soul will be torn apart. The fate of her death was already written by Heaven, and she was not even allowed to carve the tombstone herself. But she doesn't. She used her heart blood to fake her own death and escaped alone, escaping into the depths of the Forbidden Land of the Demonic Abyss. However, she bumped into the most terrifying villain in the book, Demon Lord Yin Wuxie, on the Bone Throne. In the past three hundred years, no one had asked him if it hurt, until Su Wanning's first sentence was not to beg for mercy but to ask him if he had ever had a dream. Two sacrifices judged by the script, in the countdown to death, decided to join forces to tear up this entire "fairy world rules" that was based on the pleasure of killing supporting characters.
