[Rules-based horror + eerie campus survival + campus version of Delta Force: Search, Fight, Extract + infinite-loop survival]
A group of strangers were all transported to a school where every teacher was a ghost.
Everyone had to attend class.
Students who passed their classes earned credits, which could be used to upgrade doors, windows, and classrooms,
helping them hold back attacks from the ferocious ghost teachers.
While the other students carefully spent their credits upgrading classrooms,
Chen Tian acquired the Zhong Kui Hook,
a ghostly artifact that let him open blind boxes by spending credits or years of his life.
Playing it safe was out of the question.
Though it was a blind box,
it could yield ghostly artifacts, supplies, food, and even beautiful campus idols.
While everyone else was fighting to survive, Chen Tian was gambling with his life.
It's okay, but why did it stop updating?
