With his extraordinary ability to identify fish and predict fishing seasons, along with his exclusive live-water technology, Shen Yan earned his uncle two million yuan in fishing profits, only to be dismissed with a mere twenty thousand. Furious, he cuts ties, taking his core technology and all his customers with him. Using an old wooden boat, he ventures into Devil's Reef and hauls in a boatload of rare wild seafood in a single catch, making a spectacular comeback. After losing access to his skills, the Shen father and son suffer one setback after another. When they come looking for trouble, they end up being humiliated instead. From then on, Shen Yan begins his journey to become the undisputed Fishing King of the East China Sea.
