Main building of the Special Search Team Headquarters, third basement level.
There is a special area with a circular structure here.
The walls are uniformly painted dark green, reflecting a chilling luster under the incandescent lights.
The fluorescent tubes seem to be interfered by some kind of force, occasionally emitting low-frequency buzzing sounds.
The air is filled year-round with an ever-present smell of disinfectant.
There's also a faint mist of unknown origin drifting across the concrete floor.
Looking around, there isn't a single window for ventilation.
The building's inner circle is an arc-shaped wall, evenly inlaid with nine heavy iron doors, marked with conspicuous numerical labels.
The environment appears exceptionally oppressive and closed off.
And yet, the entrance on the east side of the corridor connects to a spacious hall.
The hall is furnished with several rows of cold metal long benches.
