Lin Mu's punch knocked up a lot of dust and debris, clouding their vision. But once it settled down, they could see the effect on the wall.
"Huh… It could actually withstand it." Lin Mu was surprised.
The wall now had a hole in it that was about half a meter deep and equally as wide. Fine cracks were also spreading from its edges and had ended after growing for about ten centimeters. While this looked decently big, one must know that Lin Mu's fist was enough to punch through a meter thick sheet of solid steel.
For a rock wall to limit the damage by this much was rather impressive, especially considering that there were no formation arrays reinforcing it. It was also not made of any precious material, but was just some common rock. And yet it was able to withstand so much damage.
