He took a deep breath and found the reason. It was this sudden, inexplicable drowsiness. If someone affected by it slept, then all would be well. On the other hand, if they fought the drowsiness and won, congratulations, for the ghost would soon be knocking on their door.

Combining this with the letters in the envelopes, Yang Xiao confirmed that Room 701 was indeed the administrative office, which meant it likely concealed crucial clues.
