Zhou Yu, heir to Zhou Shipping, is framed at his engagement banquet—publicly jilted, stripped of his inheritance, and sent back to his fishing village with nothing but a broken wooden boat. He is given three months to earn 50 million on his own. At his lowest point, he awakens the Master Fisher System, yet never takes shortcuts. Starting with one net and one fish, he works hard and uses his wits, operating with integrity and supplying quality goods. He punishes bullies who undercut prices and cheat fishermen, growing his fleet alongside brothers and fellow villagers who stand by him. Finally, he passes his grandfather's test, crushes his cousin's schemes, reclaims everything that is his, and keeps his promise to leave no one behind.
