Zhou Haichuan, a veteran, suffered a severe injury to his right leg while saving a fellow soldier. After being medically discharged and returning to his hometown, his life grew increasingly difficult. His wife, Wu Caifeng, resented his disability and poverty. She took the house, their savings, and the fishing boat left by his father, then heartlessly abandoned their daughter, Niannian, who had leukemia. On the day he was thrown out with nothing, Zhou Haichuan plunged into the sea once more to save Liu Qinghe, the village beauty. By chance, he activated the bone whistle left by his father and received the inheritance of the Divine Dragon. With boatloads of valuable catches, he earned the life-saving money his daughter needed. From a destitute, wounded veteran with nothing, he gradually acquired fishing boats, a fleet, an aquaculture farm, and a home of his own. In the end, he saved his daughter and found love and a new life again.
