Every Stone Chamber had four doors, and Bai Youwei had walked through several rooms, all exactly alike. Even if someone tried to make a mark, it couldn't change the fact that the Stone Chambers seemed like "clones" of each other.
Continuing like this, there was no way to determine whether the Stone Chamber she entered was a new one she had never entered before or an old one she had already been through.
Bai Youwei squatted in the middle of the Stone Chamber and reached out to touch the spot where the waste batteries had just been placed; the hard stone brick gave no indication of any mechanism.
So, where had the batteries gone?
And why had the "Z" inscribed by Shen Mo disappeared?
"Listen..." Asarina pressed her ear against the north door, "There are no sounds anymore."
The previously approaching sounds of panting and footsteps had vanished completely as they entered this Stone Chamber.
Why was there such a big difference after just walking into another room?
