Although the court officials had been focusing their attention on the military affairs in the South recently, they were still aware of some news about the North Country.
In particular, the news of North Country's troop review alarmed officials, realizing that the North Country had grown beyond control with the appearance of its two hundred thousand-strong army.
However, with the Southern rebels yet to be eliminated, they lacked the energy to pay attention to what was happening in the North Country.
Before the Southern rebels were put down, going after the North Country could very likely lead to being caught between two fronts. Therefore, the court officials had a very clear stance on the North Country: they chose to ignore it, pretending it did not exist.
