Back in the 1980s, Chen Lin breaks free from the cowardice of his previous life. After awakening a system that helps him revive the coastal fishing trade and protect his family, he gains abilities such as locating seafood, keeping it fresh, and farming aquatic products. He devotes himself to protecting his widowed sister-in-law, Jiang Lili, and his niece, Wenwen, who suffers from congenital heart disease. Facing harassment from local bullies, schemes by relatives, and commercial suppression by the powerful Zhao family in the seafood industry, Chen Lin builds up capital through a coastal harvesting business and cures his niece's serious illness. With the help of trustworthy partners, he overcomes his rivals' repeated attempts to obstruct him, establishes an aquaculture cooperative, helps the villagers prosper through hard work, and finds sincere love of his own.
