After being reborn, Hai Xiaoman awakens as a little girl in the Great Yong Dynasty, unloved by anyone. Her father has disappeared, her mother has fallen ill, and her grandmother calls her a worthless burden. All her family has left is a shabby thatched hut with a leaking roof. But she neither cries nor makes a fuss. Guided by the Sea God, she takes her little wooden bucket and heads out to gather treasures from the sea. She collects seashells at low tide, catches green crabs among the rocks, digs for razor clams on the beach, and gathers sea cucumbers in shallow waters. Kelp can be sold for money, laver can be exchanged for grain, and even giant clams can yield pearls! In her hands, worthless fish and shrimp turn into delicious meals and silver. She leads her mother and brother on the road to great riches. But why does the poor little boy she rescued look more and more like the cold-faced prince as he grows up? How has a little girl who simply goes beachcombing become the Princess of Fuhai?
