Jack continued to stay in his incorporeal state and monitored the spaces. The interval never shortened. It was never more than a minute before the spaces changed places. He would need extreme speed to cover the distance in that short interval. A speed that he didn't possess even with his high dexterity stat.
Jack lost track of time as he monitored the spaces. He finally decided to return to his body after he felt his link with his physical self getting weakened. When he was about to enter his body, he experienced a strange sensation.
'Hm…?'
Since he entered the incorporeal state, he had sensed this place to be unusual. This place was unlike the outside world. He accommodated that sensation to this place's special structures of having the multiple compartment spaces that kept on moving around. Now that he had averted his attention from those compartment spaces, he noticed that strange sensation had nothing to do with them.
