Item #613, which Ves dubbed the B-stone, exhibited simple properties. It blocked spiritual energy. The higher the mass, the more effective the blocking strength.
Ves could easily pierce a sheet of B-stone as thin as a fingernail with a spiritual jab.
However, layering several sheets of B-stone on top of each other increased the blocking strength as if they were a single whole. This made working with B-stones a lot more convenient.
He continually cut more and more rectangular sheets from the B-stone and kept layering them against each other. He kept doing this until his full-strength spiritual probe could no longer pierce through the material.
"It's kind of strange." Ves scratched his chin. "My spiritual energy loses a bit of force and energy if the B-stone isn't thick enough, but it's still able to go through. However, the moment I add in just a single sheet, the B-stone turns into a solid wall. I can't even get past the front door anymore."
