This is the story of Luo Jie, a dockworker at Shaluo Harbor who has been exploited for ten years by the local tyrant Zhang Wancai through a fraudulent debt supposedly left by Luo Jie's deceased father. After being humiliated on New Year's Eve, Luo Jie uses his father's legacy, the Book of Tides, to venture out alone and gather seafood, earning his first fortune. He buys a battered fishing boat named Lucky Prosperity. With extraordinary sailing skills, he braves storms and navigates dangerous reefs, catching wild large yellow croaker and bluefin tuna. At the harbor's grand auction, he decisively defeats the bully and publicly exposes the truth behind the fake debt. Ultimately, he takes over the docks, establishes a new order, and restores the glory of the Fishing King.
