"Mirror?"
Upon hearing this, Dai Lin stopped his pen and looked towards Gu Yanan.
"Yes, that's right. At the time, we also found it very strange..."
Dai Lin remembered the first clause of the Hospital 444 contract that he had forgotten and then recalled.
"Every day when you wake up, you must look in the mirror to make sure there isn't a black inverted cross on your forehead. If you find a black inverted cross, never, ever approach a Demonic Department Doctor."
This point was in stark contrast to the hospital's official rules. The hospital staff rules clearly emphasized that whether one is a doctor or a nurse, if an inverted cross appears on their forehead when looking in the mirror, they must seek treatment from the Demons Department immediately.
