The entrance to the gymnasium's basement is an ancient portal that flickers. Along the way hang old kerosene lamps, several times the number found in other places, resembling a seal that binds spirits and wards off demons.
Beyond the portal lies a super massive bunker labyrinth.
The main structure of this labyrinth is formed by a large number of crystals coagulated on the flesh's surface layer.
The entire labyrinth isn't a flat layer; instead, it's like a spherelike structure, with gravity distributed very irrationally, making people inside feel like ants crawling through a hollow tree.
In the labyrinth are numerous secret chambers, but what surprises Lin Yi is that those imprisoned within these chambers are not outsiders; they're either Sports Students or Physical Education Teachers.
