The Red Devil walked past the Necromancer. After continuing down the narrow tunnel for a little bit, the undead entered an underground area that was as large as a spacious hall.
This was the rather sizeable hideout of the Black Order.
There were networks of tunnels resembling an ant hill underground, and numerous Necromancers could be found walking around inside. They were either busy carrying around various grimoires or scanning through important-looking documents. Some were even dragging away crying and resisting children.
In addition, there were summoned zombies standing in rows like some kind of statues. The Necromancers were studiously examining them one at a time.
The location the Red Devil headed to was the depository where the other Red Devils were being kept. It pushed open the steel door and entered the room.
