In the winter month of the sixth year of Tianqi, Li Chengfeng of Zhao Country mobilized a hundred thousand troops, launching a strike across seven thousand miles within a month, achieving nine victories in nine battles, advancing unimpeded all the way to beneath Han Yang Pass. After besieging the city for half a month, they finally captured Han Yang Pass in one fell swoop, sending shockwaves across the realm.
Upon hearing this news, several princes and princesses of Zhao Country underwent drastic changes in temperament, especially the Sixth Prince who had previously led a sudden attack on Han Yang Pass, resulting in the annihilation of his entire army, and in his anger, accidentally killed several maids.
The Crown Prince was initially training troops at the rear. Upon receiving the news, he ceased all training and rushed back to the front line overnight to personally lead the assault on the two counties of Yunxiang.
