"It's open..." Outside the narrow passage with the fire door, Anzhi Tianlan and Guigu stood side by side, looking inside at the already open door.
No one knows who opened it.
Behind the door was a wide staircase, and on the wall directly opposite them was a window barred with steel rods. They saw the thick black night outside.
Anzhi Tianlan looked down at her feet.
It was the door handle that used to be on the fire door, now thrown at the entrance of the narrow path by someone.
When she and Guigu were walking here earlier, she saw the door handle thrown out from a distance.
The handle lay on the tiles covered with thick dust, and the dust told them about the people who had been here before—a row of four footprints in the walkway reflected the flashlight, and besides these, there was a trail of bloodstains.
