When Lin Wan stepped into the abandoned campus holding the rusty school badge, the red compass was pointing to the coordinates of her missing sister. The blood-stained student handbook oozes thirteen rules in the moonlight: *Do not respond to the cry of the plaster statue/Forbidden to gaze into the eyes of the person in the mirror/Please synchronize your breathing when the piano plays on its own* - Violators will become the new carriers of the curse.
The seven trapped people formed the "Night Watch" alliance: Lu Xingzhe, a genius reasoning boy, found a Latin prescription hidden in the manual, a sick girl Cheng Xiaoyu's asthma spray was engraved with the pharmaceutical group's LOGO, and ghost teacher Jiang Linchuan's white coat was dripping with fresh formalin. When modern student ID cards emerged from the specimen jars in the biology laboratory, they discovered that the 217 teachers and students who were burned to death thirteen years ago were eating away at reality through the cracks with a temperature difference of 17°C.
On the eve of the collapse of the mirror world, Lin Wan finally understood the inscription left by her sister on the back of the school badge - *The sacrificer must be so hateful that he is willing to become a monster*. When the dawn bell rang, the piano keys froze at the speed of the mirror image, and deep in the pupils of the survivors, the rust-red rules were being reorganized.
