Lin Chaochao is transformed into a cannon fodder who cannot survive three chapters in a fantasy novel. He is bound to the [merit system] and must prevent several key villains in the book from turning black and destroying the world in order to accumulate merit and rebuild his body. The first task is to prevent the demon king who will destroy the world in the future from falling into the devil's path in his youth. So she sneaked into the Demonic Abyss and took good care of the young man who was spurned by the righteous and covered with scars. She gave him the only warmth, but after he fell in love with her, she "died" in front of him to complete the task. Years later, he has become the number one demon in the Three Realms, frantically searching for her reincarnation, but he doesn't know that she has changed her vest and is saving the next beautiful, powerful and tragic villain.
