The Tang Army had effectively completed the occupation of the northern part of Qin Country, and the indigenous people there had no intention of resisting, having been numbed by the relentless war.
The westernmost West Wall Fortress continued to resist, but the battle there was no longer significant. As a border area of Qin Country, West Wall Fortress had little industrial foundation, and resistance against the Great Tang was merely a joke.
After killing his entire family, Liu Zhian resolutely prepared to represent Great Qin in resisting the last attack of the Tang Empire.
However, his troops only resisted for two days before collapsing under the crushing force of the Tang Empire's Armored Corps. Shortage of ammunition was one reason, but another was the Qin Army's loss of will to fight.
A shell landed, and an entire regiment chose to surrender, with hundreds or thousands raising white flags upon encountering the Tang Army's reconnaissance units.
