Qin Yang is born with the ability to explore seabed treasures, going out to sea to treasure hunt with his cousin Qin Yaozu, only to have his dividends rolled away and be ostracized in public. Lin Group President Lin Wanyu feels gratitude for a lifesaving grace in his childhood and gives all-out help. Qin Yang accidentally fuses with the Sea King Pearl to awaken sea-controlling divine powers, salvaging massive gold to help Lin Wanyu vie for a ten-billion-level order. Facing Qin Yaozu and Lin Qiusheng's ship-boring and high-seas manhunt, Qin Yang makes a desperate comeback to punish the villains. After obtaining the ancient shipwreck chart, he abandons his fantasy of sudden wealth, transforms into a maritime guardian, opposes overseas treasure-stealing forces, and guards the precious cultural relics on the seabed.
