In his previous life, Zhou Haichuan squandered his family fortune, helplessly watching his wife and daughter suffer and die young. Although he owned a large seafood company, all that remained was endless regret. Reborn in 1980, he returns to his impoverished, desperate circumstances just as creditors arrive to demand repayment, nearly assaulting his wife and daughter. Armed with a lifetime's worth of memories of gathering seafood and doing business, Zhou Haichuan vows to make up for everything he owes them. The gambling wastrel, long accustomed to contempt and scorn, completely transforms himself, earns a fortune, buys new clothes, furniture, and a bicycle for his wife and daughter, and devotes himself to his gentle wife and well-behaved daughter. With nothing but the sea, he fights his way toward a stable, prosperous, and happy life.
