Having defeated by Li Jue, Yang Feng fled to the foothills of the Xian；
and he came up to offer his services as soon as he heard the Emperor’s journey. Seeing it was necessary to fight now, he drew up his line of battle.
Guo Si’s general, Cui Yong, rode out and began a volley of abuse.
Yang Feng turned and said, “Where is Xu Huang？”
In response out came a valiant warrior gripping a heavy battle-ax. He galloped up on his fleet bay, making directly for Cui Yong, whom he felled at the first blow. At this the whole force dashed forward and routed Guo Si. The defeated army went back some seven miles.
Yang Feng rode forward to see the Emperor who graciously said, “It is a GREat service you have rendered： You have saved my life.”
Yang Feng bowed and thanked him, and the Emperor asked to see the actual slayer of the rebel leader. So Xu Huang was led to the chariot where he bowed and was presented as Xu Huang of Hedong.
the Emperor recognized the achievement of the warrior.
then the cavalcade went forward, Yang Feng acting as escort as far as the city of Huaying, the halting place for the night. The Commander of the place, Duan Wei, supplied them with clothing and food. And the Emperor passed the night in Yang Feng’s camp.
Next day Guo Si, having mustered his troops, appeared in front of the camp, and Xu Huang rode out to engage. But Guo Si threw his army out so that they entirely surrounded the camp, and the Emperor was in the middle.
