On the verge of despair, Lin Chaosheng discovers that his father's heirloom compass can point to what he desires. Relying on the skills learned from his father, he harvests the sea for lost treasures and goes out to sea to catch fish. Facing oppression from his uncle's family, he strikes back aggressively. Protecting his grandmother and younger sister, utilizing high-grade seafood found through the compass, and establishing a partnership with the largest restaurant in town, he builds up his base on the deserted island, develops and expands all the way, establishes his own fleet, leads the villagers to get rich together, and lives a happy life.
