Compared to the previous fifty meters width, a kilometer is naturally considered very large. But to a twenty-thousand-strong army, what does a kilometer matter?
Even if each person only needs half a meter of space, the width of a kilometer would at most allow Caiqiu's army to line up 2,000 people horizontally. Such a small number of people, thinking of breaking through the Xia Army in one go, would be pure wishful thinking.
However, Caiqiu's strength is indeed astonishing!
Hundreds of Xianyang Level fighters attacking simultaneously, the Xia Army's Divine Machine Crossbows and bows and arrows were completely depleted within less than a quarter of an hour. And when these ranged methods failed, what followed naturally was close combat.
