For Zhou Tian, there was no difference whether the cave dwellers hide underground or not. He could pull them out purely based on his will. If he wanted to, he could immediately subdue these cave dwellers. But if he chose not to, they could escape unscathed.
However, it was clear by the current situation that these cave dwellers had no way of escaping Zhou Tian's grasp.
As soon as the idea formed in Zhou Tian's mind, his spiritual power quickly scanned the underground locations of the cave dwellers under his control. In a short span of time, under Zhou Tian's power, every cave dweller felt their bodies tighten, followed by an involuntary rising out of the ground.
