Late at night, the darkness as thick as ink tightly enveloped the entire building.
A few ceiling lights emitted a ghastly pale halo, dragging long, bizarre shadows along the corridor.
Upon reaching the fifth floor, Professor Zheng's steps unconsciously became lighter and slower.

A sharp, piercing scream emanated from one of the wards, echoing through the empty corridor.
This cry seemed to disturb the patients in the other rooms; subsequently, more strange noises arose, one after another.
Some sounded like the deep growls of hungry beasts, some sounded like desperate pleas under torture, and others were inexplicable murmurs.
