The marble wall moved aside, revealing the door behind it.
The door was about two meters wide and there was a button next to it. It seemed to be an elevator to enter and exit the laboratory.
But because it had not been activated for many years, it was covered with mottled rust.
As the marble wall covering the outside moved away, the thick rust was scratched and fell straight down with a 'clang', making a faint echo.
Fortunately, the elevator's indicator light was still on, so it should still be working.
This was too lucky! Song qingxiao was both surprised and happy to find the escape door.
There was only a descending sign on the button. She suppressed the excitement in her heart and pressed the button with the handle of the dagger. The people from longevity technology should have stopped the elevator on this floor when they evacuated. After she pressed the button, the elevator door slowly moved to the side with a stiff creak.
