After entering the valley, the main battle group and the Thousand Cattle Guard battle group advanced methodically towards the enemy's fortress. The huge army formation was awe-inspiring.
Over 1,600 sets of armor and vehicles spewed steam that almost drowned the entire mountain path.
The other three battle groups guarded the entrances and exits of the mountain range.
This mountain range was vast, but there were only three mountain paths in and out. It completely cut off the enemy's escape route within the encirclement and relieved the main attack force of any worries.
This was also a characteristic of the Great Tang. Their strict control of technology resulted in a huge gap between civilian and military technology.
Civilians had never seen a mobile vehicle; at most, they had shock-absorbing tires for horse-drawn carriages. In contrast, the military had steam-powered armor and steam-powered track vehicles.
