Ten years ago, the Canglan Empire's First Fleet was wiped out. Deputy Commander Lu Canghai was executed for treason, and overnight, the Lu family became known as the family of a traitor.
Ten years later, Lu Yuan, Lu Canghai's son, is assigned to the empire's shabbiest destroyer, the Wavebreaker, as acting captain. It's a floating coffin with a broken cabin lock, expired torpedoes, and a half-deaf sonar operator.
Everyone thinks this is all his life will amount to. The son of a traitor should consider himself lucky to have a roof over his head.
Until, in the rain, a submarine from the Redflame Federation surfaces...
Until one of those two torpedoes hits its mark...
Until everyone realizes that this unlucky ensign reads nautical charts differently from anyone else.
A blue light flickers in his mind, allowing him to predict enemy ships' courses, spot weaknesses in their armor, and calculate the best tactics. He has no idea where this power came from. He only knows it's connected to something that sank to the bottom of Zhenhai Harbor ten years ago.
Connected to his father's death.
Connected to a shocking treasonous conspiracy buried for ten years.
From destroyer to light cruiser, from cruiser to aircraft carrier, from the Madman of the Wavebreaker to the Overlord of the Deep...
He turns the tables against the odds and defeats the strong with the weak, proving in an age of battleships and big guns that naval battles have never been decided by whose ship is larger.
But as the truth is revealed layer by layer, he discovers that...
The one who betrayed his father came from within the empire, while the mastermind behind it all belongs to an even more powerful organization.
The real enemy was never on the surface of the sea.
