Three days later.
Wuguan.
As its name suggests, this pass commands a mountain that rises abruptly, overlooking the chaotic north ridges, with only a small path winding its way through, intermittent and yielding an imposing stance of "one man guards the pass, ten thousand cannot breach."
Unlike the mountainous Yu State, Huai State is a plain, and beyond Wuguan is flat land.
If Huainan County is the water gateway of Huai State, then Wuguan is the throat of Huai State; losing Huainan County means losing the water advantage at worst, but losing Wuguan equates to losing Huai State.
However, as the throat of Huai State, the troops stationed at Wuguan are not as many compared to Huainan County, less than ten thousand.
It's not that Prince Huai undervalues Wuguan, but to reach Wuguan, one must first breakthrough Huainan County, then Wuguan, a natural barrier, can be held even by a few troops.
Even if Huainan County falls, the garrison in the county city can retreat to Wuguan.
