Former Fisher King Xu Shanhai suffered a shipwreck, losing his father and wife. To raise his daughter alone, he sold his fishing boat, put away his sharpness, and worked uncomplainingly for twenty-eight years. On his birthday, a ten-yuan cake was swept to the ground by his daughter, and all his sacrifices were met only with contempt. Heartbroken and disillusioned, leaving behind an account book, he resolutely left home and returned to the sea he had been away from for many years. Relying on his supreme skills, he went from catching seafood at dawn to mastering the "Guihai", repeatedly winning top-tier seafood and once again becoming the Fisher King looked up to by all. Facing his greedy daughter and son-in-law, he no longer compromises; amidst wealth, dignity, and family affection, he walks towards a new life truly belonging to himself.
