The ghostly being had disappeared.
It left a single yaksha mask hovering in front of Gu Qing Shan.
This yaksha mask was the manifestation of the last of the ghostly being's power, so it was completely different from any other yaksha masks Gu Qing Shan had ever seen.
It was not disgusting.
It was a pure-white mask painted with a pair of thinly opened eyes using black shade, other than that, it was blank.
If one took a careful look, they would find that the shades that made up the irises of the mask flickered between red and black, appearing like they were both moving and not, highly animated.
Lines of glowing text quickly appeared on the War God UI:
[This is a unique yaksha mask, never before seen within the lengthy flow of history]
