Fireflies.

The bullet flew through the air; without any obstructions, it reached the massive head of the Centipede.

The Centipede still didn't seem to react; it was like the bullet was invisible to the eye.

Isaac widened his eyes and noticed that the Centipede didn't have any reaction.

The bullet finally reached the massive eye, and since there was nothing in the way to stop it, the shot was successful.

*Bam*

The bullet crashed onto the eye, and the sight which Isaac expected didn't happen.

''What... The... Fuck...'' Isaac staggered backwards after seeing the Centipede's eye being fine!

The destroyed bullet landed on the ground, it showed that it hit its target, but the damage was nonexistent!

The Centipede didn't have any reaction; instead, it was still looking straight at Isaac, but soon that changed.

The ground started trembling and shaking; the culprit for such an event was the Centipede, whose massive body suddenly moved, but an only a little bit.

*Bam!*
