The "sister-in-law" in the village is beautiful but weird. She takes cold baths all day long and is addicted to eating carrion. Her bath water was turned into a "tonic wine" by her brother, which attracted the villagers to rush for her. In fact, my sister-in-law is a mermaid. My brother and my mother actually colluded with the blind Granny Wang to raise me to be a fish girl. At the critical moment, my sister-in-law secretly helped me and asked me to scatter her insect eggs into the wine vat.
