Unemployed aquaculture specialist Lin Chen returns to his hometown on the Shandong coast and accidentally activates a sea-land space within his ancestral fish-shaped jade pendant. Starting from gathering seafood to pay off debts and farming fish, he teams up with returning agricultural operations specialist Su Wanqing to build roads, construct cold storage facilities, set up cooperatives, and create marine pastures, ultimately transforming a dilapidated fishing village that everyone wanted to escape into a modern maritime pastoral paradise with industries in every season and tourists year-round.
