After failing the college entrance examination, Jiang Nan is mocked by the entire village as a good-for-nothing. His father is disappointed, and the family is drowning in debt. Just when he hits rock bottom, he unexpectedly becomes bound to a marine ecosystem perception system that allows him to discover rare seafood. Starting with a single bucket of golden butter crabs that sells for 68,000 yuan, Jiang Nan joins his brother Wang Dayong in harvesting seafood along the shore, buying boats, rescuing people, protecting the sea, and discovering sunken ship artifacts. Step by step, he turns his life around. Not only does he amass a fortune worth tens of millions, but he also leads Nanwan Village in establishing a fishing cooperative, helping the entire village grow wealthy together through rules, hard work, and skill.
