Jiang Haichuan, Dongwan's ace captain, pours his entire fortune into building the brand-new Haiyue vessel. After spending ten years training a group of apprentices, he expects to celebrate the launch of his new ship. But on the day of its christening, his eldest apprentice, Zhou Kai, joins forces with the others to betray him. Exploiting loopholes in the paperwork, they seize the ship, the company, and all its contracts, leaving him with only the old, leaky wooden boat Guichao, which is barely holding together. Worse still, his father and older sister are forcibly taken aboard and sent straight into a deadly storm! At his darkest moment, Jiang Haichuan awakens the Myriad Tides Sea Eye system. Steering the dilapidated Guichao through a tornado, he risks his life to rescue his family. He refuses to forgive betrayal lightly, but he lives by one unbreakable rule: save lives first at sea, settle scores once back on shore. Starting with repairing his broken-down boat, he sets out to build a fleet of his own.
