The sound waves traveled up from the seabed, creating a shockwave that sent countless ripples across the ocean's surface.
All sorts of fish and marine life hidden in this sea region now surfaced. Many large fish even tried to leap onto the various ships, but they couldn't jump high enough.

The naval officers present all wore grim expressions as they watched the scene unfold.
