The Tang Army's tanks and armored vehicles have started to appear frequently outside the city. In fact, the main forces of the 3rd Corps are less than 15 kilometers from Wuyang City.
The reason they haven't launched a probing attack yet is actually because the Tang Country has already agreed with the Qin Country to temporarily halt military actions against Wuyang.
On the other hand, the Qin Country has not been idle in recent days. Although they haven't further mobilized troops, they are indeed reinforcing their own defense lines. However, due to lacking equipment and supplies, their reinforcements are somewhat at the mercy of fate.
Stacked bricks and haphazard sandbags, combined with various buildings and obstacles on the city's edge, constitute the last line of defense the Qin Army can rely on.
The lines of defense built outside the city actually serve no real purpose. Even Zhang Xuan himself doesn't hold out hope for those trenches, let alone the officers below him.
