In January 2023, a guard and his faithful dog patrolled the grounds of a Chinese boarding school. His routine was typically mundane, involving occasional chases after stray chickens. However, something had changed. A student had vanished three months earlier, casting an unsettling aura over the surrounding woods. On a fateful day, the guard's dog suddenly erupted into a frantic bark, diverting his attention. Intrigued and apprehensive, he cautiously followed the dog's lead, arriving at an abandoned shed on campus. What he saw would never leave his memory. Suspended from the trees, the missing student dangled lifelessly, held by nothing more than a pair of shoelaces.
