The faint sound at the door attracted Shen Xiaoxiao's attention. She got up and slowly walked over.
In fact, Shen Xiaoxiao was quite curious. If there was a sound at this place, was it someone outside or someone else? Wouldn't they be discovered? Or could they not hear it?
Shen Xiaoxiao raised her head and looked through the crack in the door. Not far away, there were still two burly men guarding them, but they couldn't hear them from such a close distance?
Shen Xiaoxiao looked at the metal back door and carefully touched the thickness of the wall.
Could it be that the wall was too thick, so the faint sounds could not be heard from outside?
In fact, Shen Xiaoxiao's hearing was extraordinary. Perhaps ordinary people could not hear these sounds.
