Wei Yuan spread out the map and pointed at it three times, saying, "The Witch Clan is coming in three separate groups this time. The strongest force is from the northwest, possibly tens of thousands, the west holds roughly twenty or thirty thousand, and the southwest is the weakest, perhaps less than twenty thousand."
This was Wei Yuan using the power of Qingming to sense changes in the energy of the world. The troop counts were estimates, not precise, but the relative positions were quite accurate.
The Witch Clan's three detachments were close, the nearest less than two hundred miles away, while the farthest remained beyond three hundred miles, and they were also several hundred miles apart from each other.
