Reborn in a fishing village in 2000, 18-year-old Zhang Sheng awakens the Matsu Believer System, gaining seafood positioning through three daily bows. He takes his older brother Zhang Hai and childhood friend Liu Zhiqiang to go sea fishing, catching large yellow croaker, giant grouper, etc. to save money, buying cell phones, and ordering a 25-meter deep-sea fishing boat. He asks Yu Kejiao to design a villa, and takes fellow villagers out to sea for dividends. The system guides fish schools, obtains bluefin tuna, etc., encounters a leatherback turtle giving coins, gets to know buyer Zhao Qing, and makes millions in revenue in a single trip. He respects the ocean, releases juvenile fish, installs monitoring, and plans the deep-sea fishing fleet. From street vagrant to counterattack, he leads relatives and friends out of poverty, sticking to his original intention.
