"I swear I heard a giggle, but I do not know where it is coming from. The giggle even sounded near my ear so I can assure myself that I am not hallucinating." Adrian muttered as he looked around.
Adrian then stopped looking round and looked at two directions that he has yet to consider. He did not consider up and down. He first looks upwards and spread his wings. He then flapped his wings in order to take off as there is no upward wind to carry him.
Adrian flew about a hundred meter until he hit something like an invisible wall. He stuck his face near the invisible wall and saw the nether realm just outside of it. He could more or less infer that the ceiling that he touched is none other than the boundary of the fox marble.
