Zhang He and Gao Lan broke through toward the west after covering the rear, successfully escaping Liu Bei's encirclement thanks to their combined efforts as two great martial artists.
It can also be said that the two managed to escape because Liu Bei and others were not targeting these Inner Qi Manifestation experts, as they were difficult to kill. The significance of defeating Yuan Shao outweighed the defeat of these experts, allowing the two to escape.
After breaking out from the battlefield, the two gathered nearly a thousand routed soldiers with their prestige. Without daring to linger, they decided to head towards Ye City, feeling the need to swiftly convey Yanzhou's defeat to the rear, so they could prepare and avoid Liu Bei exploiting the opportunity.
