Jiang Yu is pushed aside by Jiang Tao and receives only a dilapidated wooden boat when the family property is divided. However, using a national-level marine database model from his previous life, he accurately locates fish and stages a spectacular comeback. Su Muxue invites him to become the exclusive seafood supplier to Haiyan Tower. Jiang Tao retaliates by poisoning the catch and destroying fishing nets, while outside investors use monopolistic tactics to suppress Jiang Yu's business. With Director Li's support and fishermen such as Tie Zhu standing by him, Jiang Yu fights back with a transparent fishing port and patented traceability technology. He brings down criminal forces and monopolies, establishes the Hongfeng Port Cooperative and a distinctive fishing town, and joins forces with Su Muxue to help the fishing village prosper. Their good days are only beginning, and their achievements eventually earn international certification.
