Li Yusen, a young man driven into bankruptcy and burdened with debt, returns to his hometown. By chance, he is struck by lightning on the beach and gains extraordinary abilities: generating electricity, breathing underwater, and storing things inside a nautilus shell. He begins gathering and catching premium seafood to earn his first fortune. Along the way, he meets Su Qing, the CEO of the Delicious Fresh Grand Restaurant. The two fall in love, marry, and join forces to build a business. They acquire a pier and seafood purchasing station, establish reliable supply channels, and tame a great white shark to explore the open sea. After discovering sunken treasures and rare marine delicacies, overcoming malicious competition, and securing long-term contracts, Li Yusen achieves success in both business and love. Together, they embark on a new chapter of expansion into the provincial capital and exploration of the deep sea.
