Fresh out of college, Jiang Chen is struck by tragedy when his parents borrow a million yuan to buy a fishing boat and head out to sea, only to perish in a storm. Crushed by enormous debts, he faces creditors from the entire village demanding repayment. At his lowest point, Jiang Chen unexpectedly bonds with a Dragon Pearl, gaining supernatural abilities to see through the deep sea, transform his physique, and control seawater. Using the pearl to catch rare seafood, he quickly repays his debts and befriends Meng Fei and Lin Ruoxi, a woman from the business world, while repeatedly thwarting the schemes of seafood trader Zhao Wanlong. Later, he purchases an ocean-going fishing vessel and establishes Chenhai Group. As he investigates the truth behind his parents' shipwreck, gathers the complete Dragon Pearl, and obtains the power of the Sea God, he battles pirates on the open sea, stops a massive tsunami, and dedicates himself to marine conservation.
