In his previous life, Zhao Dahai was a hopeless drunk who indirectly caused the deaths of his wife and daughter. He died consumed by regret, only to be reborn in the 1980s! Given a second chance at life, he turns over a new leaf. Armed with the water-repelling treasure left behind by his father, the Shark Pearl, he overcomes his fear and becomes an outstanding deep-sea diver. By harvesting valuable seafood such as ornate spiny lobsters and yellow-lip croakers, he earns his first fortune. He gradually buys boats and builds factories, ultimately winning back the hearts of his wife and daughter while leading his entire village to prosperity and becoming a legendary Dragon King of the Sea.
