Liu Hengchang's question hit right at the border army's sore spot.
Over the years, the border army has barely held on by relying on the fortifications of the city walls when the Rouran Cavalry invaded. It could be said that as long as the Rouran Barbarians retreated, it was considered a major victory for the border army.
The large number of civilians abducted by the Rouran Barbarians were beyond the border army's ability to rescue.
General Fan sighed with some shame: "Commander Liu, this general feels the same pain for the abducted Da Liang citizens. But you have seen the actual situation of the border army. In reality, there are only about ten thousand cavalry capable of fighting. Once the infantry enters the grassland, they can't even find a trace of the Rouran Barbarians."
