Unlike their previous encounters with supernatural phenomena, both the Player Group and the Student Group seemed to have adjusted to the atmosphere of Honghuai Ghost School. After all, aside from the eerie atmosphere, the shadowy figures that appeared around the school had all sorts of strange abilities, but were nowhere near as frightening as the supernatural incidents the three middle-aged players had encountered before.
Whether it was the "Terrifying Music Classroom," ranked fifth among the Seven Mysteries of the Campus, or the sixth-ranked "Student Who Didn't Exist," both the Student Group and the three players got through them without a scare or any danger.
According to the rumors about the "Terrifying Music Classroom" that Ai Xiaojia remembered from the Campus Forum, if someone entered the music classroom in the school's Comprehensive Building at midnight, the door would close, and the piano inside would begin playing by itself. Anyone trapped inside had to sing along with the piano accompaniment. Only by getting both the lyrics and the melody completely right could they leave.
It sounded as though this mystery shouldn't have ranked below the "Death Screening Room" in difficulty, but those who vanished inside the "Death Screening Room" merely reappeared safely somewhere far from Rainbow Locust No. 1 High School, without suffering any harm.
In the "Terrifying Music Classroom," however, if an intruder's singing failed to satisfy the Ghost Creature lurking inside, they would be forced to keep singing. They had to sing until their throat hurt so badly they almost wanted to snap their own neck, until their voice grew too hoarse to make another sound, and still keep singing until the Ghost Creature was satisfied.
Compared with such a terrifying ordeal that tortured both mind and body, being transported to another district or city might actually have been easier.
