Fu Wan, who had lived a miserable life, was reborn and returned to 1987. In a desperate situation where she was bullied by her husband's family and something happened to her family, she swallowed a fish pearl and awakened her underwater breathing ability. She decisively divorced and fled with her daughter. She used her supernatural powers to catch rare seafood in the sea, and started a business together with her family and cousin Fu Liang to become rich. During this period, he dealt with the entanglement of the Shen family, the jealousy of the villagers and competition with his peers. He even unexpectedly reunited with his father who was also reborn, and unlocked adventures such as bird's nests and sunken ship treasures. She wisely fights evil forces, protects the countryside, and transforms from a frustrated daughter-in-law into an "ocean overlord". She not only changes the fate of her family, but also takes her family to set sail towards the treasures and hope in unknown seas.
