As Fengg Ji and Guo Tu timed their actions perfectly, successfully deceiving the Xianbei and entering Jundu Mountain from the astrologer before easily capturing the unguarded Juyong Pass, Zhang He of Bingzhou also made his move.
Although Zhang He did not understand why Sheni Pei would open the Juyong Pass to let the Xianbei in, he still chose to trust Sheni Pei when the situation arose.
Zhang He knew Sheni Pei's pride; apart from Yuan Shao, Sheni Pei wouldn't bow to anyone, let alone barbarians. However, the subsequent defeat shocked Zhang He and made him have ominous thoughts.
After passing Jundu Mountain, the terrain is flat—a fact acknowledged by everyone. Sheni Pei was defeated by the Xianbei, and the Xianbei displayed legion talent, which could no longer be termed as mere strategy.
