Very quickly, Yuan Shao's Army, which had encircled Liu Bei from the rear, was dispersed by Zhang Yan leading a large troop force. Subsequently, Zhang Yan followed the orders in Lub Su's letter, dividing the Black Mountain Army into ten units to conduct continuous harassment of Yuan Shao's Army on the periphery, aiming not to kill but to disrupt their senses and cause misjudgments.
Meanwhile, Liu Bei's Vanguard had already consecutively pierced through Tian Feng's defensive lines, but the repeated breaches of these lines had left peerless valiant generals like Guan Yu, Gan Ning, and Xuu Chu exhausted, their originally unstoppable momentum gradually eroding away.
Upon breaking through the tenth defensive line, Liu Bei's Vanguard finally became entangled in a stalemate with Yuan Shao's Army under Tian Feng's expectant gaze.
