Originally, the Liaodan Great Khan sent a few warriors to Lingbei, who waited left and right but Cai Wei never showed up. Upon discovering that Zhao Yun was Cai Wei's most capable assistant in Lingbei, they took advantage of the deep, quiet night to kidnap her, hoping to lure Cai Wei out.
Tuoba Liang was deeply enamored with Zhao Yun and had people keeping an eye on her constantly. When he learned that Zhao Yun had been kidnapped, Tuoba Liang flew into a rage, led his troops, and pursued her captors throughout the night. After a day and night of pursuit, they finally caught up to them in a forest.
A fierce fight ensued between the two parties, and after several bouts of combat, Tuoba Liang was able to rescue Zhao Yun as he had wished.
