"Is it hollow?"
The echo from the floor wasn't very distinct, but Su Ge was still sure that there was another layer below.
Out of curiosity, she immediately stood up and looked around, trying to find an entrance to go down.
Her gaze finally fell on a slightly ajar door.
She slowly walked over, gently twisted the doorknob, and inside it looked like a utility room, filled with a jumble of medical equipment.
Feeling it wasn't the place, Su Ge was about to close the door when her eyes suddenly fell on a vintage clock on the wall.
The items in the utility room were all covered with dust, yet this vintage clock was very clean.
Although it wasn't spotless, compared to other things, it was much cleaner.
Could there be something wrong with it?
Su Ge carefully walked over and cautiously reached out to try to take the clock down for a look.
Unexpectedly, it seemed to be nailed to the wall; she pulled it a few times but couldn't take it down.
