A fully deployed Tier Three Grand Array could cover an area dozens of miles wide, but due to insufficient manpower and a lack of need, it had been shrunk to a size of two hundred zhang.
Counterintuitively, an Array's Defensive Power isn't necessarily stronger the smaller it is.
The larger the area it covers, the more Spiritual Qi the Array Banners can draw in. Every Array has an optimal size for stability. The Seven Luminaries Demon-Slaying Array, for instance, is best when covering an area five li wide, which can easily accommodate over two thousand Demon Suppression Army soldiers.
Of course, an isolated array cannot hold out forever, so Yang Jing also planned to set up some Tier Two Arrays outside the Seven Luminaries Demon-Slaying Array for mutual support.
