Half of a broken gun lay in the bloody mud at the northern foot of Yinshan Mountain, and the sound of Hun cavalry's hoofbeats came from three sides. The intelligence was delivered to Xianyang two months in advance, via the military aircraft department's dedicated post road. I held down the arrow wound on my shoulder and glanced at the mouth of the valley - where Mengtian's response flag should have been. The deputy general asked me with red eyes who had betrayed us. I inserted the broken gun into the frozen soil and did not answer. Let's wait until we break out. Climb out of this pile of dead people first.
