"Damnit!"
I yelled and punched the wall of the spatial bubble.
My fist slammed into the strange surface with enough force to send a dull impact through my arm, but apart from the bluish lines running through the walls flickering like they always did whenever I attacked, nothing else happened.
There was no crack. No distortion. Not even the slightest sign that I had weakened it.
I pulled my fist back and sighed, my heart still beating rapidly in my chest.
I needed to calm down.
Getting desperate and frustrated wasn't going to produce any results. If anything, losing my composure would only make it harder for me to think clearly, and right now, thinking was more important than throwing attacks at something that had already proven it could withstand them.
I had to try other alternatives.
And I think I had an idea.
The idea lay in how I thought the barrier itself worked.
