Fisherman's daughter Lin Wan is exploited and forced into a marriage of convenience by her toxic biological family. When she runs away in defiance, she awakens the "Rare Marine Intelligence System." Using precise school-of-fish data to harvest top-tier seafood and making her first pot of gold, she fiercely cuts ties with her family. Starting from setting up a street stall at the dock, she fights her way up, establishes a fishery cooperative, builds a marine ranch and a full-industry commercial empire, tears apart toxic relatives, defeats local bullies and monopoly capital, while uncovering her own lineage as the descendant of the Sea God. Ultimately, she reaps a perfect career and love, leaving her remorseful family bowing their heads to beg for forgiveness.
