Chapitre 1136: How To Become A Demorgorg.

Their four-star demorgorg said to them. "You know what to do. I will give you 5 minutes to complete the binding process."

The initiates know what to do. They have seen it being done before and have trained for it. So they scrambled toward their assigned cells without hesitation. They had gotten access cards which they used now to open the doors of the cells. 

Inside the cell is their target. It is a demon pierced through from all sides by runic spikes. The spikes extend from the walls and pin the demons at the center of the cell. Each spike has penetrated the demon from one side to the other so their sharp tip can be seen after passing through the flesh of the demon.
