In his past life, Chen Haitao indulged in gambling, incurred massive debts, and ended up in the tragic plight of a shattered family. Accidentally reborn back to the fishing village in 1980, he awakens the seafood detection system, capable of precisely detecting marine aquatic products. Having seen the light, he wholeheartedly protects his family, starting from beachcombing and making money through solid seafood. He successively confronts village bullies and unscrupulous merchants, resolves all kinds of conspiracies, sets up a fishery cooperative, and leads the fellow villagers to make a living and get rich. Building cold storages and running enterprises, venturing into the open sea to develop fishing grounds, he starts from scratch and carves out a massive fishery career, rewriting the destiny of himself and his family.
