Flying devices hovered over the sand dunes;
Countless mechanical spiders densely packed into more than a dozen underground tunnels;
Explosions sounded continuously throughout the desert;
Human Warriors poured military goods into the stratum channels, ranging from a hundred to two hundred meters deep, through various means, while technicians at their control terminals constantly linked up with new drone swarms.
The extermination battlefield was divided into three layers.
The outer troops were responsible for blasting any new passages underground that might appear, the central main fire-power positions awaited to eliminate Blade Beast Groups surging from beneath, and the dozen or so tunnel entrances and exits were the most dangerous combat zones, where the drones' main battle took place.
Daoist Wang sat comfortably inside the command vehicle, closely observing the battlefield and the human commanders up close.
These were all unprecedented experiences.
