Chihiro and his parents drove together to their new home, and accidentally entered a mysterious tunnel on a small road in the suburbs - they went to another strange world - a medieval town. The fragrance of food wafted from afar, and Mom and Dad ate it quickly. Which one turned into a pig! At this moment, many strange and semi transparent people gradually arrived in the small town. Chihiro fled in a hurry, and a person named Xiaobai saved him, fed her medicine to prevent her body from disappearing, and told her how to find Grandpa Boiler and Grandma Tang, and had to obtain a job to avoid being transformed into something else by magic. With the help of Xiaobai, Chihiro was fortunate enough to get a job as a busboy in the bathtub. Gradually, she was no longer intimidated by those strange looking people, and learned from Xiaoling that Xiaobai was a disciple of the ferocious Grandma Tang. Once, Qianxun found that Xiaobai had been injured by a group of white flying paper people. In order to save the injured Xiaobai, she used the pill given by the River God to drive out the seal inside Xiaobai's body and the small demon guarding the seal, but Xiaobai still did not wake up. In order to save Xiaobai, Chihiro embarked on her adventure again.
