Li Xing worked hard in the big city for many years but still lived an ordinary life. During the Spring Festival, he returned to Binhai Village and unexpectedly found an old painting that could travel to a magical space inside the painting. The space was rich in beaches and amazing seafood. There were countless football-sized crabs and rare Neptune spots. There was also a vast ocean. So Li Xing carried a piece of the sea with him and started a different life of catching the sea.
