"Once when Yan Kingdom was at its strongest... it opened the gates of Yecheng Pass." Ye Shouguan said coldly, "But, even at that time, the ever-victorious Yan general Tang Yi, known as the God of War, opened the gates of Yecheng Pass in the hands of my grandfather and father, yet ultimately did not dare enter. Why?"
"Tang Yi feared that if he entered Yecheng Pass, he would be trapped by the well-fortified Xiliang soldiers on the high peaks at the sides..." Ye Shouguan looked towards the city walls on both mountain peaks, illuminated like a long dragon by lights, "And if they directly passed through Yecheng Pass to advance on Yunjing, Yecheng Pass would be reoccupied by the Xiliang army. How then could Yan's forces manage without supplies? Should they rely on the northwest winds to conquer Yunjing?"
