To Sebastian's surprise, right as he had just applied force onto the invisible barrier with the fire spiritual energy…
The invisible barrier immediately shattered into pieces as if it was an extremely fragile paper-thin glass!
"…?"
Before Sebastian was able to have the time to fully register into his mind what had even just happened, he could feel that his energy core was able to absorb even more spiritual energy into it once again!
Immediately, without hesitation, Sebastian began absorbing all of the refined fire spiritual energy that was currently within his dantian into his main energy core, and as the main energy core began absorbing the refined fire spiritual energy, the space that was within the main energy core began to expand, so that it could contain even more spiritual energy within it.
