After an unexpected accident, college student Jiang Han is reborn one year before the tragedy that changed his life. He unexpectedly awakens an unlimited scanning system that allows him to see through the seabed and tidal flats, accurately locating seafood and hidden treasures. In his previous life, reckless spending and squandered opportunities to cherish his family left him dying with deep regrets. This time, he abandons his city career and returns to his hometown to start a sea-foraging business, quickly rising to success. He buys fishing boats, launches an online seafood business, and builds a team, all while protecting his older sister, Jiang Feng, and working hard alongside his childhood friend, Zhang Haidai. Along the way, he meets the restaurant-owning sisters Meng Fei and Meng Guo, and gives his vain ex-girlfriend, Ye Tiantian, a humiliating reality check. Through steady progress and honest business practices, he transforms from a down-and-out young man into a leading seafood entrepreneur on the island, protecting his family, building his business, exploring mysterious places, and amassing wealth.
