Lu Ming, a frail fisherman, is schemed against by his own relatives and accidentally falls into the sea, only to miraculously survive. Thanks to a good deed from years ago, a true dragon grants him a dragon pearl, awakening supernatural abilities to control water and sense valuable seafood. After returning home, he rescues his wife and daughter. With the dragon pearl and his wife Lin Wan's secret seafood sauce recipe, Lu Ming calmly outsmarts the relatives who plotted against them and unscrupulous merchants, leading his entire village to prosperity. As his business gradually expands to the provincial capital, he steadily builds his seafood trade into a thriving enterprise, transforming the life of an ordinary man from humble beginnings.
