This shits just ridiculous. Probably the worst torture in the history of torture.
SAND FLOOR ROOM
So basically it’s a torture device, where a person is put into a room with slow moving sand-paper at the bottom. There is no way out.
The person has to walk forward to keep from getting send to the corner and scraped.
Eventually after days of walking, the person will get tired and won’t be able to anymore.
What happens next, is pretty gruesome and self-explanatory.
