He had only travelled a few meters on the water when he saw the shadow again; it moved under him. It was still very deep down, so he waved it off and kept walking.
But when he got to the midpoint of the lake, the shadow got closer, rushing in his direction like a torpedo.
Silva reacted fast, he kicked the floor, launching himself back and into the air. The ice cracked and a massive monster the size of a skyscraper blasted out.
It was like a crocodile made of ice-white scales, with fins rather than hands. The water splashed all around and the ice scattered in every direction.
Silva only saw this creature for a moment, but he could tell that it was massive and extremely dangerous. He landed a few meters away, watching as the massive monster slammed into the ice.
It didn't try to chase him at all, it simply slid back into the water, and right before Silva's eyes, the ice that had been shattered was fixed; it froze instantly and covered it.
