Part-time sailor Lin Yuan desperately rescues a wealthy girl, only to be kicked straight into the deep sea by her. On the brink of death, he awakens the heritage of an ancient true dragon, gaining the power to control water and master the seas. With a single net of premium large yellow croakers netting a million, he establishes the Dragon Saliva Pavilion to sweep the seafood market, retrieves night-pearls from deep-sea shipwrecks, crosses over into the jewelry industry to shock the entire city, single-handedly crushes ancient martial grandmasters with just a drop of water, and makes prestigious families bow in submission. Wealth, power, and beauties all fall into his embrace, yet on the night of his ascension, a black fog locks the sea and abducts his beloved, leaving behind a dragon-hunting totem. If you want to save her, come to the Lost Demon Sea.
