Lin Dazhuang is a hardworking, honest fisherman who shoulders the burden of supporting his family alone. By a stroke of fate, he receives the sea's special favor and gains the ability to perceive the treasures and resources hidden beneath its waters. Driven by his sense of responsibility toward his family, Lin Dazhuang devotes himself to the ocean, gathering seafood along the coast and sailing into distant waters, working tirelessly to turn his life around. He stands by his principles, treats others with generosity and loyalty, and works hand in hand with a crew of honest sailors, sharing both good fortune and hardship. Undaunted by the dangers of the sea, he ventures into treacherous reefs, fulfills the tasks entrusted to him, and discovers ancient artifacts from sunken ships. Rather than becoming obsessed with enormous wealth, he honors his promises and returns entrusted treasures to their rightful owners, while responsibly converting the remaining finds into money. After becoming wealthy, he never forgets his roots, honoring his elders and treating his friends with kindness.
