A veterinarian from a modern pet hospital traveled through time and became the wife of an exiled prisoner. She was assigned to the most barren penal colony with her three children. She relied on her "modern veterinary" skills to sterilize sick pigs, and then built an animal hospital, shared medicine for humans and animals, and a border animal husbandry town. Finally, even the imperial court came to learn from her experience - she went from "sterilizing cats" to "sterilizing pigs in the village". She raised a family with laughter and tears, and also fed a land.
