Somewhere by a waterfall in the Magical Beast Mountain Range.
This was a spot the Apothecary had "carefully selected." It was not particularly deep within the Magical Beast Mountain Range, so there were no fifth- or sixth-rank magical beasts.
Nor was it too close to the outskirts of the Magical Beast Mountain Range. If they needed to venture deeper into the mountains to search for medicinal herbs or the like, they would not have to travel too far.
The Apothecary had also cleared out all the nearby fourth-order magical beasts, allowing Xiao Yan to cultivate here in peace.
