Under this unique howl, the ultrasonic waves carried in the killer whale calls were all interfered with.
Then, amidst the howling, the silver four-clawed monster moved with a speed that surpassed the killer whales' imagination.
Fear unspeakable rose in the eyes of the two killer whales, for they couldn't describe what kind of speed it was.
Originally, the silver four-clawed monster was a good hundred meters away from them.
In the deep sea, this was a safe distance for them; no species could launch a sudden attack on a killer whale group from hundreds of meters away.
This wasn't land, nor was it the sky; it was the vast ocean.
Here there were strong currents to contend with, and the unique pressure of the deep sea.
In the deep sea, the fastest fish they had seen was the sailfish.
But even the sailfish couldn't come close to one-tenth of the silver four-clawed monster's speed.
Sound followed by shadow.
