After Theo's decision, the group finally came out of the room, staring at the gentle slope that would bring them to the first level.
Suddenly, the lamps started shining, illuminating the whole building, but it wasn't too bright that it would harm the monsters. Instead, the brightness increased slowly, so the monsters thought the sun came out.
There was no natural light coming in because of the architecture, but Theo could see that the light was too dim in his perspective.
Alea and the others quickly used their Night Vision Glasses.
It turned out the light was similar to that of the night, allowing them to operate normally with the glasses.
Theo also put it on while checking the first floor.
He found walls upon walls around the nests, making it look like a labyrinth. It wasn't that confusing, but still enough to block monsters' visions of the others.
