Yan Fei was startled as he realized that the disappearance of the glass cabinet had caused a change in floor pressure, resulting in hundreds of tiny probes emerging on the floor, ceiling, and surrounding walls. These probes corresponded with each other two by two, and whenever they aligned in any vertical, horizontal, or lateral orientation, they would emit a beam of red light. The red light emerged from one probe and traveled into the corresponding one, cycling endlessly without pause. These red beams formed a rectangular prism, trapping Yan Fei within, rendering him unable to move an inch from where he stood.
