Boom!
A muffled thud rang out.
The massive Sea Overlord Submarine gave a sudden shudder, then slowly sank into the base lake.
Liu Yan, a Class B Submariner, was obediently staying in his cabin. Through a porthole nearly half a meter wide, he watched seawater rapidly cover the glass.
He could not help recalling the brief speech the Colonel had delivered before this behemoth set sail: "Everyone, the forty-eight Sea Overlord Submarines of the Sea Overlord Legion will travel over eighteen thousand kilometers to launch a surprise attack against the Three Great Sea Races.

Liu Yan drew a deep breath, his heart filling with lofty ambition.
