However, the magical force field of the Ape Tribe is a black technology developed based on Earth's mutation rules. It can perfectly block all communication signals, and its intricacy exceeded even Yan Fei's imagination. Therefore, no matter how many reconnaissance devices Yan Fei had, once they entered the buildings, they immediately lost contact with Yan Fei behind the scenes. Unless Yan Fei personally entered those rooms, no one could break through the magical force field's barrier.
After the advantage in numbers also failed, Yan Fei did not deploy more reconnaissance devices to continue the investigation because he had already thought of an excellent method to solve this problem. From now on, he stopped considering what the conditions inside these unknown rooms might be. He only needed to use the process of elimination to identify the room where the Dream Island hostages were held from among the unknown rooms.
