Chen Qing and his wife, Su Xiaohe, have worked diligently for years to support their entire family. Yet his parents have always shown extreme favoritism toward his older and younger brothers. When the family property is divided, Chen Qing receives nothing but a dilapidated boat and a rundown house converted from a pigsty, while his brothers take the good boats and all the family savings. Facing his family's unreasonable treatment, Chen Qing signs the agreement in bitter resentment, cuts all ties with his family, and vows to build a better life. Unexpectedly, he discovers a mysterious golden pill inside the boat. After swallowing it, he gains the power of a Dragon Pearl, allowing him to breathe freely underwater and sense the fish beneath the sea. Determined to change his fate, Chen Qing sets out to use this extraordinary gift to turn his life around.
