Back in 1995, in a poor fishing village, Zhang Shuisheng returns burdened by the regret of dying on the high seas in his previous life.
His family has nothing, his mother is bedridden with lung disease, they are deep in debt, and his reputation is in ruins.
After activating the Rare Catch System, he ventures across reefs and into the open sea, angling for large yellow croakers and battling giant giant grouper.
He turns the ocean into a treasure trove, earning money for life-saving medicine, paying off old debts, and shouldering his family's burdens.
The former prodigal transforms himself, using his skills to turn his fate around. He will not let down his family, or Liu Xiaoxia, who truly cares for him.
