Isn't this cheating? [2/2]

"Rest in peace," I whispered softly as I squeezed the trigger.

Like an airsoft rifle, the M24 sent a bullet silently and without recoil. I would not have believed I had fired at all had it not been for the carnage at the other end. It was unlike anything that I have ever seen in real life before.

I say real life because it was a sight that most anime and video games used. The bullet I fired wiped out everything it touched in its path. I mean that literally. The blessed bullet turned everything it passed through to golden ashes.

Normal bullets, after finishing off an undead, simply dropped its body to the ground. Blessed bullets left no residue, not even blood. I kept trying to confirm that what I was seeing was real. When the scene didn't change no matter what I did, I asked my partner.

"Aira, I'm not dreaming, am I?"

[No, my lord, the blessed bullet you fired traveled like a normal bullet but vaporized nineteen zombies on its way].
