Xu Xiao bought an injured little white snake at a barbecue stall. After raising it, she found that it was very spiritual. At night, she even dreamed of the white-haired snake demon Bai Yin. The two made a marriage contract. As the days went by, the white snake grew in size and often wrapped around her body. Xu Xiao saw the video and mistakenly thought the white snake was going to devour her, so she cruelly released it into the virgin forest. The white snake was found late at night, and soon Xu Xiao was targeted by gangsters. At the critical moment, Xiaobai transformed into a human form to rescue her. Only then did she realize that he was a well-organized snake demon, and that the marriage contract in her dream was not an illusion. What's even more surprising is that she possesses the gene of a demon hunter. After joining the Demon Management Bureau, she and Bai Yin started a sweet and fantastic daily life with shemales.
