"Tang Li," Mei Quzhen seemed to have a good relationship with Doctor Tang, directly addressing him by his name, "keep an eye out for me. Once the graveyard is closed, if anyone patrolling comes by, it's up to you."
"Alright, Director Mei."
The graveyard was scheduled to close at five.
At four-thirty, the graveyard began to repeatedly broadcast a message, urging those visiting graves to leave.
Once it was five, Mei Quzhen checked the surroundings, then walked to one of the tombstones.
She opened her medical kit, and from inside, she took out a vial of blood. She unscrewed the cap of the tube and then... poured the blood onto the tombstone!
Dai Lin was taken aback and quickly said, "Doctor Mei, there are surveillance cameras here!"
"No problem," Tang Li replied. "Nothing can be seen from the monitor room. No one will come here to patrol either."
Then, she opened her medical kit again, took out a doll, and threw it in front of one of the tombstones.
