Linghai University is a rusty prison that swallows up memories and lives.
The first day Ni Mingjun stepped into the school gate, he discovered something unusual - rust-like blood stains oozed from the walls, prying eyes were hidden behind the cracks in the door of the old school building, and his body was slowly being devoured by some invisible rust. Transfer student Zhang Huai told him that people in this school disappear every few years, including his sister. The mysterious girl Ling Huixiang looked on coldly and said that Ni Mingjun was already a "sacrifice".
When the rust creeps into the heart, the truth will emerge - something older than death is buried beneath the ground of this school.
