When the lights on that floor of the tower came on, Minos and everyone else shielded their eyes, given how strong it was. But after the True Celestial left, they gradually got used to the place and spotted what was in the area.
They were in the center of what looked like a colossal building, about 300 meters away from many rooms separated from each other by the same distance, following the shape of a circle, with the cultivators practically in the center of the area.
Apart from the side rooms, which had opaque glass walls and transparent doors, there didn't seem to be any exit to this floor, either out of the building or to the upper level.
Minos narrowed his eyes, but reflexively had a feeling about where his future lay and looked towards the ceiling, where a closed golden structure stood, with a clock counting down the time to the opening of the second floor.
