Before Yao Yuan's eyes was a large hall the size of a football field. However, when compared to the openness of the universe, it was extremely small.
The hall even felt more cramped thanks to the various mechanical paraphernalia like cogs, parts, gears, and wheels that covered the four walls. It gives the impression that they were inside some kind of mechanical structure. Yao Yuan could feel his eyes getting blurry, following the different turning motions of the many different gears in the room.
