Lin Mu was certainly not expecting for such an effect to happen because of the boulder collapsing fist. Before when he used spirit qi with Boulder collapsing fist, the effect was completely different and now it was something else.
"Look at the next tree behind it," Xukong spoke.
Lin Mu snapped from his shock and went to the next tree that was at a distance of three meters from the previous one. There he saw that another small hole had been bored into it as well. Except this time, it didn't pierce all the way through and stopped about half of the way.
But that was not all. As the point where it stopped, the hole had increased in size as if the needle had exploded at the end. Lin Mu probed deeper with his spirit sense and saw internal cracks in the trunk of the tree. He reckoned that if some force was applied to the trunk, it may just split apart.
