Lin Mu placed his palm against the wall, and the moment his skin touched the weathered wood, his expression changed as there was something inside.
At first, he could only sense a faint spatial fluctuation, so faint that an ordinary immortal would have completely overlooked it. Even someone with a decent understanding of the Spatial Dao might have mistaken it for the natural spatial instability that existed within the Mad Demon Depths.
But Lin Mu knew better. He closed his eyes and allowed his Spatial Perception to spread through his palm. His consciousness slipped past the physical structure of the wood and entered the hidden spatial layer contained within it.
"What is this?" His brows slowly rose. as the space inside the wall was immensely compressed.
It reminded him of a spatial storage ring, yet the comparison was still inadequate. A normal spatial storage treasure created a pocket of space that was separated from the outside world.
