At 40, Jiang Yue is reborn 20 years into the past, returning to 2002. He avoids the tragedy that once left his nephew dead after falling down a mountain and himself with a crippled leg. After awakening a sea-foraging system, he can exchange tools for other people's goodwill and jealousy points. He dives into the sea to collect razor clams, sea cucumbers, large yellow croakers, and other seafood, selling his catches to buyers and quickly making a fortune. He supports his family, treats his relatives kindly, helps his older sister open a shop, and finally gets together with the woman he loves. Through sea foraging, he transforms his family's impoverished circumstances and gets back at the snobbish, jealous villagers, building an increasingly prosperous life.
