Lin Mo fell into the Silent Hill Sanatorium, and the rules were the iron law of life and death. The only chance of survival is to temporarily "distort" the rules of the burning spirit: running away turns into sliding, and the response turns into coughing... But every time it is tampered with, black crystals that corrode life are coughed up. When the nurse's metal heels and life-threatening whispers echoed in the corridor, he had to risk everything to find loopholes in the rules - because the administrator's cold giant eyes were already staring at this abnormal "virus" in the dark. Rewrite the rules, or be rewritten by the rules.
