In an 1980s fishing village, Wang Ziwen returns to the day his father died. In his previous life, he was idle and irresponsible, missing his chance with the woman he loved most, Feng Shuihua, and spending the rest of his life drowning in regret. Given a second chance, he binds himself to an intelligence system that accurately reveals the locations of seafood treasures. After splitting the family estate, all he has left is a broken wooden boat. But by gathering seafood late at night, he hauls in huge catches of swimming crabs, large yellow croakers, and pearl oysters, filling his boat time and again. He earns money to support his family, helps his elder brother and childhood friend A Zheng, puts the arrogant village teacher Jiang Xiaojun in his place, and eases Shuihua's mother's concerns. He repairs his fishing boat, buys a motorcycle, saves money to build a house, and uses hard work and his system to rewrite his impoverished fate. Protecting his family bonds, he finally marries the woman he loves and builds a prosperous, fulfilling life by the sea in the 1980s.
