Jiang Ruan, a genius in metaphysics, turned into a fake daughter through a book, and was assigned two tasks by the Prince of Hell. He must redeem the sickly villain Huo Shiyu within two years and accumulate 10,000 merit points. After being kicked out of the house by the Jiang family, she relied on fortune telling, catching ghosts, and popping melons to accumulate merit, slap the bad guy in the face, expose the scumbag's plot, and resolve the crisis of her best friend. In the process, she and Huo Shiyu gradually got closer to each other. She used metaphysical means to help him avoid trouble many times, and the two gradually fell in love while getting along with each other in a humorous way. In the end, Jiang Ruan not only completed the task, but also gained love, bringing Huo Shiyu back to the right path and living a wonderful life.
