Former criminal profiler Lin Mo is involved in the "forbidden game". Every time he enters a field, he must abide by strange rules——
"Hospital Rule 3: Don't talk to the red nurse when the red light is on"
"School Rule 7: Do not stay on the rooftop for more than 10 minutes."
"Shopping mall rule 5: 999 yuan products must be purchased"
Those who violate the rules will be "liquidated", and his awakened [Forbidden Eye] can see loopholes in the rules:
"Red Nurse only attacks people who look directly into her eyes - then lower your head and run away."
