After his mana had recovered, Ash teleported above a large stone slab that rested right on top of the massive stone door.
He appeared without making a single sound, completely silent, as if he were a ghost.
Absolute Concealment was already active, cloaking his body so well that even the air didn't seem to notice him.
There was a small gap between the two sections of the enormous stone door. It was narrow, but just enough for him to peek through, like a tiny window, revealing a limited view of what was on the other side.
It reminded him of the size of a keyhole, offering only a partial glimpse into the mysterious chamber within.
Carefully observing the darkness behind the door through the gap, Ash locked onto what he could see and teleported inside.
As soon as he arrived inside the room, his instincts kicked in.
Without wasting a second, he moved behind a nearby pillar and kept himself completely hidden.
