Qin Xiaoyu was originally a cute boy from the fishing village. After being angrily smashed by salted fish from the sky, he accidentally fell into the exciting and chaotic world of the spirit world. He has many adventures and meets funny partners and rivals who are also friends and foes. Along the way, Qin Xiaoyu relied on wit and nonsensicalness to break the rules, disrupt the three realms of monks, demons, and gods, face the game of fate and power, and gain growth, friendship, and love. In the end, a group of "little people" who were originally marginalized used their humor and courage to trigger changes in the spiritual world. The whole novel has a tight rhythm, ups and downs in the plot, and constant laughter. It tells a fantasy growth adventure in a relaxed and humorous way.
