When Chen Tianyi, a numb social worker, encountered an indiscriminate murder at a subway entrance, he rolled down the escalator while escaping in a panic. When he opened his eyes again, the world had been completely turned upside down.
He fell into "Jingchuan Middle School" that was blocked by endless fog.
Here, the weird "school rules" are iron laws, and the price for violating them is not demerits, but being "cleaned up" in various unimaginable ways.
Seemingly ordinary classrooms, canteens, dormitories, and radio gymnastics are filled with murderous intent.
And the "teacher" who enforces the rules and the numb "old student" don't seem to be alive...
Partnering with the mysterious girl An Yao, Chen Tianyi discovered that this school is actually a "cognitive reconstruction field" that has been operating for decades.
"Transfer students" are all "experimental subjects" who accidentally fell into the system. After "observation and evaluation", they face the fate of "cleaning up" or "assimilation".
The "sleep time" after nine o'clock at night is the only window they can take a breath and explore the truth.
However, as they touched upon the core secret in the dusty archives, the void-piercing gaze in the mirror told them:
The "rules" of this school are far from simple as they appear.
And deep in the thick fog, that "she" who has been mentioned all the time may be the source of all terror...
