Chen Hua, a young man from a fishing village, and his younger brother, Chen Ming, are drawn into the mystery of an ancient merfolk pact dating back a thousand years after a typhoon splits a mountain.
After discovering that their mother carries deep-sea blood and their father has mysteriously disappeared, the brothers resolutely enter the mysterious world of the merfolk to save their family.
Caught between conflict among merfolk tribes and the covetous eyes of scientific research institutions on land, Chen Hua uses human knowledge and technology to kindle the flames of civilization in the dark abyss: teaching, improving tools, pioneering metallurgy, and even linking the two worlds through satellite communications.
He grows from a son seeking revenge into a merfolk king, forging alliances amid blood and intrigue and setting off a colossal wave that spans species.
Chen Hua says, "With our forces defeated and our situation desperate, then let us use human technology to rewrite the laws of this ocean!"
