Li You is reborn in a poor fishing village in the 1990s and becomes bound to a fish intelligence system. The system regularly provides information about fish locations, sea conditions and potential hazards, as well as seafood market prices. Using this information, he accurately catches valuable seafood such as large yellow croaker and grouper while avoiding dangerous waters. With the money he earns from selling his catches, he buys a fishing boat and leads his family and fellow villagers to prosperity through fishing. Seizing the business opportunities of the era, he transforms himself from a struggling fisherman who repeatedly returns with empty nets into a renowned seafood magnate.
