After the family property is divided, Su Qing receives a barren tidal flat that nobody thinks highly of. The white fox that has always been by her side often guides her to valuable treasures hidden across the tidal flats. With a keen eye for the natural resources of the mountains and sea, she builds reliable partnerships with merchants and runs a legitimate seafood business, steadily increasing her income through honest dealings. Her uncle's family grows jealous and repeatedly schemes to make things difficult for her, only to suffer the consequences of their own plotting. Su Qing remains calm and refuses to fight recklessly, resolving disputes according to the rules and carefully protecting the tidal flats. Through diligence and hard work, she builds a new home and, together with her family, makes a peaceful life by the sea.
