Xuan Kong reached out, seemingly not exerting much force, yet those hands were like talons, effortlessly separating two entirely different materials of stone.
After taking the object into his hands, Xuan Kong then realized, this was not stone at all, but rather the skeletal remains of some creature, merely resembling stone.
Just as he lifted the bone for close examination, a moaning sound suddenly echoed from below the sinkhole.
However, the sound was so faint, it seemed more like a noise caused by draughts passing through corridors.
Xuan Kong merely turned his head to glance, then withdrew his gaze, as this sound posed no threat to him.
Meanwhile, Xuan Chu, climbing on the rock wall, naturally heard this sound too.
He could even sense a gaze from below the sinkhole, tightly fixed upon him.
Xuan Chu instantly felt a tingling sensation all over his skin, despite not seeing what lurked beneath the sinkhole.
