Xie Mingyu is a simple and honest seaside fisherman. He makes a living by fishing and working part-time as a seafood vendor. However, he is repeatedly bullied by Zhang Lei, a bully in the local seafood market. Zhang Lei monopolized the seafood supply in the entire region, driving up prices and bullying small vendors. Xie Mingyu's meager income was often robbed by him, and even the sea areas out to sea were controlled by his power. In an accident, Xie Mingyu obtained a mysterious golden finger, which not only allowed him to accurately locate fishing groups, but also sensed the distribution of rare seafood in the sea. His fishing efficiency was greatly improved, and he even caught top-quality seafood that ordinary people could hardly see. Relying on the adventure brought by the golden finger, Xie Mingyu got rid of Zhang Lei's oppression. He started by setting up a stall to sell seafood, gradually expanded the scale, acquired fishing boats, built a seafood supply chain, and gradually broke Zhang Lei's monopoly. He attached great importance to love and righteousness, and led the fishermen around him to get rich together. With his own hands and golden fingers, he counterattacked from an ordinary fisherman to a well-known seafood tycoon, and wrote a legend of getting rich by eating from the sea.
