Liu Chuan failed in business and fell into a huge debt of two million, his wife jumped into the sea, and creditors pressed on his door. In a desperate situation, a white dragon drilled into his body, and from then on he gained the ability to sense aquatic life, control fish schools, and evolve fish and shrimp. He first caught a nine-jin large yellow croaker to repay his debt, and then caught ornate rock lobsters, bluefin tuna, and premium blood-red dragons for Shen Qingyue of Dayang Aquatic, repeatedly cracking the interception, poisoning, and schemes of Li Wei and Shen Qingshuang of Huangting Aquatic. In the end, Liu Chuan raised six billion with shipwreck treasures, bought back all the shares of Longgong Group at a low price, sent Li Wei, Shen Qingshuang, and Li Lingling to prison, married Shen Qingyue as his wife, and became the chairman of Longgong Group.
