After transmigrating into Su Haisheng, known as "Foolish Hai" in Qingluo Village, he is pushed into the sea by his scheming cousin and awakens the supernatural ability to hear the thoughts of sea creatures. Breaking free from his family's oppression, he separates from the old family household and establishes himself independently. Using his ability to communicate with animals, he recruits seagulls, seals, sharks, and other creatures to form an army of marine beasts. He also takes a master and learns the healing arts of seafood. Starting with a small stall at the pier, he overcomes bullying by powerful local families, foils commercial sabotage, and puts an end to a plague in the nearby waters, earning an official commendation for his compassionate efforts to help the people. In the end, he establishes Su's Seafood Trading House, builds a harmonious family, and earns the respect of his neighbors, forging a path to success through kindness and hard work.
