Spirit Hall Secret Prison.
There was no sunlight here.
The surrounding walls were built from special Black Stone, covered in patterns that suppressed Soul Power.
An ordinary Soul Master locked in here would find their Soul Power becoming sluggish within three days.
After ten days, even Martial Soul Possession would become difficult.
Xiao Wu sat in the innermost part of the cell.
She hugged her knees and lowered her head, her face pale.
There were no iron chains on her.

That was the most terrifying part.

Gui Mei stopped outside the cell door and looked at her through the Black Stone
