He didn't know how long it had been before Charles awoke, as if from a deep slumber.
The first thing he did upon waking was to immediately look around vigilantly.
The humanoid monster had vanished, his location had changed, and he was locked up, confined in what seemed to be a cell of only ten square meters, with nothing else inside except a heavy iron door in the distance.
Everything he had been carrying was gone: wallet, relic, clothes—all were missing, leaving Charles completely naked.
Charles could also see blood seeping from where his prosthetic limb joined his body, as if someone had tried to pull off the prosthetic while he was unconscious, but had not succeeded.
From these clues, Charles swiftly grasped his current situation—he had been captured by those strange creatures.
Although he didn't want to admit it, this was a good thing—they had chosen to imprison him rather than kill him outright, which meant there was a possibility of communication.
