During the great famine of the Da-Xia dynasty, the Su family was exiled to the desolate beaches of Lingnan. The father was heavily injured and the whole family was on the verge of death. In a desperate situation, 5-year-old lucky treasure Xiao Bei activated the "Tidal Conch Seal" in the palm of her hand, carrying goods to shuttle back and forth to the modern era! Utilizing the price difference between the two worlds, Xiao Bei turned the "seafood waste" considered smelly in ancient times into top-tier private kitchen luxuries of the modern era, cashing in heavily, and even brought back modern supplies such as antibiotics, invisible nylon nets, and industrial deodorizing soda ash. The Su family "cute baby sets policy, parents govern" made a fortune quietly. Facing the oppression of corrupt officials and powerful gentry jointly sealing off the sea, the Su family made ice for preservation, built modern concrete wave-break dikes, led 500 exiled convicts across the island to technically reverse their fate, monopolized inland trade routes, and was ennobled to make a counterattack!
