The border between Liangzhou and Yongzhou.
There is a continuous mountain range of thousands of miles. Because there are so many monsters and beasts in it, this mountain is called Beast Mountain.
This mountain is also a notoriously dangerous place, and ordinary friar dare not enter at all.
In the heart of this mountain range lies a valley.
There are many buildings in the valley, which is hard to imagine. In such a place, there is such a large area of buildings, which are all built of black stone, and there is eerie darkness in the night.
This place is called Poison Prison Valley.
Apart from a few top friars in the Yunshui world, such as Wuzui, who knew about the existence of Poison Prison Valley, the others seldom knew about the existence of this place.
The name of Poison Prison Valley was also changed later, and the popularity was much greater before.
