EXP!

"Who the hell are those guys?" I muttered to myself as I sat in the corner of a 7-11 store, sipping on an energy drink.

I hadn't used my skill on the newcomer who saved me, fearing that it might offend him as well. However, that mysterious man's level was completely off the charts. 

It had just dawned on me that I had been underestimating the capabilities of the humans. I had previously thought that levels around 20-25 were considered high, but it appeared that wasn't the case at all.

Did I think they possessed supernatural powers as well ? Absolutely not. It is more likely that the guy was just exceptionally skilled in combat, perhaps on the level of someone like Mice Tyson on steroids.

"I guess I'm still pretty weak," I sighed, feeling like a frog that had been living in a small pond. I used to be the big frog there, but now I've hopped into a river where there are much stronger and larger frogs around.
