Inside the prototype, Floor 6.
When Rio opened his eyes, he found himself standing inside a closed room; the lighting in the place was rather dim.
'There are no artificial lights here… It looks like the material of the wall is glowing by itself and providing this dim lighting…'
Rio spread out his mana detection and found that no one was present beside him in this small room.
'Ugh, it's this cliché thing again… Whenever something wrong is about to happen, we always end up getting teleported randomly; it was the same during the Dungeon of Maya too…'
The material used on these walls can easily block the mana detection of even SS-rankers; thus, Rio could only sense the area inside the room, and his mana detection was being blocked by the walls.
Thus, he couldn't sense what was located outside of the room.
