The entrance to the lower floor of the gymnasium is an ancient portal that flashes, with old kerosene lamps hanging along the way, several times more than elsewhere, resembling a seal meant to suppress demons and spirits.
Beyond the portal lies a super-massive underground labyrinth.
The main structure of this labyrinth is formed by a large number of crystals that have coagulated on the surface of flesh.
The entire labyrinth is not a flat surface but is more like a spherical object with unbalanced gravitational distribution. Those who walk inside it are like ants crawling in a tree hollow.
Within the labyrinth, there are numerous sealed rooms, but what surprises Lin Yi is that those held captive inside are either sports students or physical education teachers; there are no "outsiders" at all.
