Wutong Prefecture is the most remote prefecture city in Baoping State, closest to the northwest wilderness.
And Black Mountain City is the most western part of Wutong Prefecture.
Beyond it is a vast wilderness, inhabited by numerous demons, beasts, and the like.
It is unknown how many monsters have mingled among them or are mixed into the city.
Further north, one must travel far to reach the so-called 'northwest bitter cold' territory of the Demon-Suppressing Great Wall, a barrier against the invasion of Baoping State by three Dao Lineages of demons.
This shows that it is a mountain city built in reliance on the mountain.

The day is nearing dusk, the sky is dim, with light rain falling.
A carriage arriving from afar stops at the door of 'Black Mountain City'.
Low earthen walls, pieced together haphazardly, managed to be constructed.
At the entrance, a queue of people comes and goes, inspected one by one by constables in old constable uniforms with sharp eyes.
