At night, the nurse's station.
This was the first time Yin Yourong and her colleague Zhang Ya were on the night shift.
During the day, they hadn't noticed anything amiss since the hospital was bustling with people, and they were too busy to feel scared; they only felt tired.
But now, as the number of people slowly decreased, and since this was the inpatient department where hardly any patient needed consultation, the entire nurse's station had become quiet.
"Yourong, do you hear anything?"
Yin Yourong, who was passing the time by reading medical books, suddenly heard Zhang Ya ask this question.
Yin Yourong looked puzzled.
"What sound?"
Zhang Ya, curled up like a quail, said with some fear, "It's that kind of voice, straining with all its might, a very painful sound, as if it's coming from the men's restroom."
Zhang Ya usually liked watching horror movies.
