The day after the tour around the refurbished Realm, Alros head to the depth of the Palace of Debauchery, where the dungeon is.
The dungeon is large underground chamber with multiple cells, big and small, to keep prisoners, usually the strong enemies that he did not plan on killing.
Currently, the dungeon were filled with the A-rank combatants of the Holy Nation, who followed the Hero on her mission to kill him. And of course, the Hero herself, the reason for her visit.
He walked down the hallways, where monsters stood attention at his very presence. He also pass two of his S-rank monsters. From what he learned, they had set up a rotation of 8 hours per session to guard the Hero.
Considering how powerful S-rank is, the guard rotation were appreciated by the Demon Lord. He will reward them but first, he planned on seeing the Hero first.
