Not only did Wan Qingshan's face change dramatically, but all the Beihu people also instantly turned pale.
That's a drone!
Everyone here is well aware of the impact of drones. On pre-apocalyptic battlefields, these small things brought shock and slaughter, known to anyone who follows the military.
But since the apocalypse, people subconsciously ignored these things.
Because drones are not very useful against zombies.
Firstly, there are no production lines, making mass production difficult.
Drone bombings were all targeted at armored vehicles; bombing zombies was too costly, and no one would do it.
What everyone pursued were essentially steel torrents, metal storms, and such things.
Drones were glamorously forgotten until recently, when people remembered their application, but mass production couldn't be achieved in a short time.
Unexpectedly, the Dawn Army actually mass-produced them!
At this moment, Wan Qingshan broke out in cold sweat.
