Zhou Hanhai is reborn back to 1982 and awakens the divine power of the Sea Emperor. To save his wife and daughter, he dives into the deep sea to subdue a hundred-pound fish king, braves dangerous reefs to gather herbs, and befriends wealthy merchants, escorted by a hundred whales and a white-naped crane! Returning through the waves in a giant ship to face his mother-in-law's family, Zhou Hanhai decisively protects his wife and safeguards the warmth of his small home. Afterwards, he establishes a fishing fleet, rising from a prodigal son to a fishing king who leads the whole village to prosperity, fulfilling his promise to protect his wife and daughter with passionate devotion and demonstrating the pure dedication of kindness and beauty.
