My sister-in-law is as beautiful as a fairy, but she has puzzling hobbies. She not only prefers algae and meat, but also frequently soaks in cold baths all day long, which is very strange. What's even more strange is that Qifeng used his sister-in-law's bath water to make wine. The wine exuded a pungent smell, but the villagers rushed to buy it like a man possessed, claiming that they didn't feel tired after drinking it, and Qifeng also made a lot of money. Qiyue was filled with doubts. She found that the edge of the bathtub was always covered with pink particles. Her sister-in-law kept it secret and warned her not to tell anyone about it. Until by chance, Qiyue heard her brother confess after drinking that his sister-in-law was the "snail girl" he kept after hiding his "shell".
