There was only one conceivable reason for my body to no longer draw in energy from my kills, and that meant I had finally reached my limit, or well, the true limit of the Non-Rank.
With my eyes regaining their clarity, I came out of autopilot, and a wave of fatigue washed over me, causing me to fall to the ground, exhausted, panting for air, and worse yet, covered in a hellacious amount of gore and grime.
'Oops…look's like I over did it…' fighting to catch my breath, I turned my head enough to observe the obscene number of unmoving shadowy figures lying around as far as the eye could see, and frankly, I wasn't surprised.
This was a common occurrence for me, and I had long since realized that my body seemed to move on its own when it came to doing tasks I found menial or boring, and cutting down wave after wave of monsters was precisely that, boring.
