An elite special forces soldier unexpectedly reincarnates in 1980 in a coastal fishing village, becoming Zhou Guoliang, a gambling addict who squandered his family's wealth. Faced with his critically ill daughter suffering from a high fever, his despairing wife Xiulan, and the relentless exploitation of loan shark Qian Zhiqiang and his family, he resolves to turn over a new leaf and make amends for the original owner's mistakes. Using his elite combat diving skills, Zhou Guoliang ventures into dangerous reefs to catch incredibly valuable wild seafood, earning the money needed to save his daughter's life. Time and again, he foils the local bully's schemes, including spreading rumors, monopolizing ice supplies, and setting fishing boats on fire. He purchases a large ocean-going vessel, establishes connections with the provincial capital's cold-chain suppliers and restaurants to break the monopoly, and leads the formation of a fishermen's mutual-aid cooperative with a transparent profit-sharing system, guiding the villagers to venture out to sea together and build their wealth.
