An hour later, thunderous roars echoed from the distance.
Two opposing positions lay directly ahead. Humans were hiding behind cover, continuously exchanging fire with the Mechanical Lifeforms ahead.

Facing the human fortifications, the Mechanical Lifeforms clearly did not think much about it and simply kept charging forward.
What shocked Li Mu Chuan was that several production lines were actually still operating behind the Mechanical Army.
Ammunition was constantly being manufactured on the production lines, then transported to the Mechanical Army at the front.
Several extremely burly-looking robots stood around the production lines, continuously picking up scrap metal or fallen Mechanical Lifeforms from nearby.
Once tossed into the production lines, they produced an endless supply of ammunition.
Li Mu Chuan stared blankly at the scene. What was this?
"How do those production lines work? These things can manufacture their own ammunition?"
Li Mu Chuan looked toward the rear of the Mechanical Army and asked several soldiers beside him.

That was what had puzzled Li Mu Chuan.
Hearing him put it that way, the soldiers understood.
However, they were not entirely sure either. "Our guess is that their technology is actually somewhat
