Therefore, when Xian'an City was besieged, the sole army stationed in Jiaoxi County that could shield the southern part of Xu State and use to restrain Chu State's advance, led by Yan Yunqing, had to be relocated and rushed to the Capital for assistance.
His departure completely sold out Xu State.
The previously planned Liang army, which was supposed to shield the south of Xu State, now utterly became a plan on paper.
Throughout Jiaoxi County, not a single troop that could honor the agreement could be found amid the turmoil in the Liang country.
With the Liang military abandoning their responsibilities and Xu Army having no contingency plan originally, who could possibly fill in the southern defensive line in such a short notice?
The southern part of Xu State was thus completely breached, leaving it wide open for Chu State to enter.
To the south of Le'an Prefecture, other than the southwest direction, there was still Sheqiu City capable of putting up some resistance.
