Chen Zhaoyuan, the founder of Taoism who has survived for thousands of years, opened a paper-making shop in hiding in the suburbs of the city. His only companions on a daily basis were two paper-making children and a civet cat. One day, Chen Ergou, captain of the Tianhai detachment of the Special Investigation Division, came to her door and asked her to investigate the girl's disappearance. As the case fermented, the Animal and Plant Research Institute of the Demon Management Bureau entered the investigation, and numerous old acquaintances appeared one after another. She was deeply involved in a huge conspiracy, and the dust-laden past slowly surfaced.
