Pei Ji downloaded a weird night shift nurse simulator and was dragged into an abandoned hospital the next second. A baby cried in the corridor, and rules written in red appeared in the medical records: [1. Don't look back] [2. Patients in ward 404 must be given medicine at three in the morning]. Violation is death.
While all the players were staring wildly in the morgue, Pei Ji stared at the rules and smiled. He has a natural ability to see through loopholes in the rules - as long as you tamper with the time of death on the medical record, you can have the ghost nurse on duty for you.
Not only that, he can also write rules for ghosts in reverse. Hundreds of ghosts walking in the morgue at night? He posted a note saying "Visiting hours have expired and unregistered persons are not allowed to enter" and raised the dean as a social animal.
