Xuanyuan Que saw that war was forthcoming, not immediately, nor a month later, but in about half a year; therefore, he did not rush to send troops, but preparation was needed in advance.
On the following day, Xuanyuan Que proposed to the Emperor that he wished to inspect the borderlands.
The Emperor expressed his surprise, "You've just arranged your marriage, and you can have a grand wedding as soon as the Imperial Astronomical Bureau sets the date. Why inspect the borderlands at this time? Why not wait until after your marriage?"
To inspect the borderlands, he did not specify whether it was Nanzhou, the Northern Border, or even the Western Frontier!
One round of inspection would inevitably take at least a year and a half, which would delay the marriage arrangements.
Xuanyuan Que responded, "There's no time to delay."
Without inspections, he would not even be able to marry on schedule; with them, there was a chance to end the conflict before the wedding date.
