The fairyland is misty, and the fairy trail is hard to find. Li Nianfan came to the world of cultivating immortals with a mortal body, and after learning that there is no hope of cultivating immortals, he just wanted to live in peace. But he didn't know—a dog he adopted, because he watched him write poems and paintings, became a generation of demon kings, Suppress one world. The tree planted behind his house, because he listened to him playing piano music, became the tree of the world, supporting the bridge between heaven and earth. A passerby he met, because of his casual enlightenment, became a sage of immortality, leading an era. Looking back—it turns out that the scholar who has been pestering him for calligraphy and painting is the painting master of the fairy world, the old man with poor chess skills is the chess master of the fairy world, and the beautiful woman who comes to listen to music every night is the number one saint in the fairy world...
