Seventh Breath: Infinite Substitute

Lin Yuan opens his new freezer and finds his homeroom teacher Chen Jianguo curled inside the frozen compartment, only the upper half, the cut neat, the scar on his brow frozen purple. Three hours ago, he saw this man pushing a bicycle, right hand on the handlebars, fingers all intact. A text message arrives: "Don't call the police. He knows about your sister." Three months ago, his sister Lin Xiao fell to her death from a building. The police ruled it suicide, but Lin Yuan knows the rooftop surveillance was tampered with. He sneaks into Chen Jianguo's office, pries open a drawer: a photo album shows Lin Xiao standing at the edge of the rooftop, video screenshots show someone pulling her in the early morning, a medical report indicates six weeks pregnant. At the bottom, a glass jar contains a right hand, the label dated yesterday, the inside engraved with "Seventh Breath."
