When his father was bitten by a shark and his legs were amputated, and his mother was forced into desperation by a vicious neighbor who kept the price low, college student Zhang Shukai resolutely dropped out of school and returned to his hometown. He was accidentally bound to the "Sea Fishing System" and received the blessing of adverse weather luck. He went to the sea to find rare goods many times, and formed a "sea-going trio" with seafood shop owner Xu Qian and village expert Xiang Jie to dig clams, fish for rare fish, and achieve bumper harvests repeatedly. After thwarting Zhang Laosan's several conspiracies, he unlocked a god-level fishing rod, strengthened his fishing boat, and finally became a "seafood tycoon", not only protecting his family, but also gaining true friendship.
