In the 1980s, Chen Haisheng, a skilled diver, is seriously injured in an accident at sea. His adoptive father and elder brother refuse to save him, already plotting to abandon him. After narrowly escaping death, Chen Haisheng gains the supernatural ability to control water and a spiritual spring space that accelerates the growth of precious seafood. He rides the waves home and saves his wife and daughter. Teaming up with restaurant owner Liu Ruyan and supplying her with rare seafood, he breaks free from his family's exploitation. He forms a diving team, establishes a cooperative, and leads the entire village in taking a hundred-ton vessel out to sea. When an ancient nautical chart surfaces, a crisis involving the Four Seas Chamber of Commerce in the provincial capital and the deep-sea ruins of Dragon King's Tomb emerges. He sets sail once more, chasing the waves into the distant ocean.
