Inside the cave, Feng Yi was waiting quietly for the situation to change. He had lost his courage and had nothing left, which meant that if he left the cave now, he might be exposed to the detection devices of the Saudi hurricane mechas.
The hurricane mechas use a bio-wave sensing system for detection, with an effective range up to 2000 meters. So, Feng Yi had no choice but to rely on the natural coverage provided by the cave to shield himself from these threats as much as possible.
To avoid any accidents, he cautiously made his way further into the cave. The most likely creature to encounter deep within the cave was venomous snakes. Over the centuries, Big Macs had become densely populated with these creatures, effectively controlling the early proliferation of local rats.
Feng Yi remained very vigilant and even set up a small tent to take a brief rest, making sure everything was settled before deciding on the next course of action.
