In his previous life, Mai Chengye was foolish and addicted to gambling when he was young. He ruined his family's offshore fish pond and was exploited by fish dealers who maliciously lowered the price. His parents became ill due to overwork and had no money for medical treatment and died early. His sweetheart was forced to marry far away. He lost all his money from breeding for many years. He was finally buried in the sea during a typhoon, and he ended up full of regrets.
Once reborn in 2008, the 19-year-old returned to the beginning of the tragedy. He has the deep-sea talent to predict the sea conditions, sense fish plagues, and understand the market price of aquatic products. At this time, the uncle's family takes advantage of his inability to repay his debts and attempts to seize the ancestral pond entrance at a low price. The fish fry in the town are hiding a deadly fish disease, and the unscrupulous fishmongers who monopolize the local sales are closing in step by step.
With more than ten years of future memories and unparalleled knowledge of the sea, Mai Chengye held on to his own fish pond, catching high-priced seafood to resolve debts, avoid fish plague losses, improve fishing rafts to breed golden pomfret and eastern star spotted, and revitalize Wenchang's offshore resources. He exposed the villainous plot of his neighbors, broke the monopoly channels of fish traders, and led the whole village to engage in aquaculture, deeply cultivate fishing ports, and develop seafood businesses. He grasped all the trends in the South China Sea era, protected his family, made his hometown rich, and created his own deep-sea fishery territory.
