-Xiaoxi Tian Land / Mountain Ghost
Entering the mountain gate along the mountain road, there is a chance to find Bintie Sha in the coffin treasure chest on the left side of the road, but most likely it will be something like Hantie Ye.
After going in, you can turn left and go up the stairs.
Be aware that there are ambush creatures at the stairway entrance.
Proceeding straight along the red line will encounter a large number of frozen creatures, including elite Mountain Ghosts and Ginseng Spirits.
You can first lure out the elite creatures to obtain their essence, and the frozen small creatures can be killed instantly when charging up.
Turning right here and going down to the courtyard will trigger a plot event.
Following the red line to the end will encounter Ginseng Spirits.
The treasure chest in the corner contains Hantie Ye, Iron Blood, and Broken Gold.
After defeating them, either walk back or follow the blue line downwards as shown in the image.
Crossing the bridge into the courtyard will trigger a plot event.
The Earth Spirit incarnate in the form of a human-faced owl will take the appointed person to the Mirror Lake.
