Psshewww

Now, how should I approach this?

Recklessly rushing in like earlier is stupid. I was stupid for even doing that, but at least the ringing in my ears has stopped.

*BOOM*

"SHIT!!"

The asshole shot another shock wave as a long-range attack. 

I quickly formed another Aura barrier to block the shock wave. 

However, it shattered just like earlier. But there was enough distance between us that I was only pushed back by a few steps.

A boom...

What if I use an Air Bomb to cancel out his shock waves? 

I think that's worth a try, right?

I started gathering the surrounding air into my palm. The vents blasting a lot of cold air helped quite a bit since the amount of air in a closed space was very limited.

In order to keep his attention away from my other hand that was forming the Air Bomb, I brandished my sword to distract him and make him think I'd attack with my sword again.
