Reborn in 1998, Zhou Haichuan opens his eyes to the very day his eldest uncle slams the table, tries to seize the family boat, and forces his mother to sign an agreement surrendering it to settle an 8,000-yuan debt. In his previous life, his younger sister dropped out of school, while his mother and older sister wasted away half their lives without a better future. This time, he awakens a Deep Blue Fishery Detection System. Starting by gathering seafood along the shore and prying abalone from the rocks, he clears the debt in two days, tears up the IOU, and saves the Haiwang. He helps his older sister catch fish and build wealth, shields her from a forced marriage, sends his younger sister back to school, and reconnects with Xu Qinghe, the woman he personally pushed away in his previous life. As long as the boat remains, the family remains. This time, he will protect them all.
