Yoko had explained to Ryan earlier that the dungeon was a single-person dungeon, meaning that each person went in and had a different experience.
According to Yoko, each world dungeon was the same and would be tailored for each person individually.
As the dungeon activated, Ryan felt his connection with Yoko suddenly terminated, as she told him it would, so he in no way could cheat.
Inside a room similar to the one inside his training tower, Ryan got a heavenly notification with a simple choice.
[Would you like to begin 'Ravier's World Dungeon'?]
[Yes / No]
Selecting yes, Ryan saw the white walls surrounding him shift, and he was suddenly inside a dark space with a series of options in front of him.
[Which ability would you like to upgrade?]
[Overlord's Pleasure Aura]
[Overlord of Lust]
[Overlord's Oath]
Ryan snapped his fingers. 'Disappointing my conversion or palace abilities weren't on the list, but at least pleasure aura is.'
