After walking around the area for a while, Luke didn't find the skeletons, and he frowned upon realizing that. It was hard to believe that the entire population of monsters and people from that world had become skeletons were all inside the fortress. It was impossible for all of them to fit in there. Luke felt that he needed to investigate more instead of heading straight for plan B and risking a failure that would leave him exposed. Besides, he needed time to prepare for that. So, it was like he had much of choice there.
"Another troublesome world… There is always the option of going to another world and ignoring this one, but I wouldn't go too far if I keep skipping this kind of enemy," Luke thought.
