Casper could control his body in middle-air with the jet boots he got. It was difficult to stay stabilized, but soon enough he got the hang of it and began to descend through the floors at a reasonable speed.
'The thing that passed here surely is strong. This hole is straight and clean, like a well-made tunnel. It's even unbelievable. It demands amazing speed and strength to do something like this.'
After five minutes, Casper could pass the floor he was before, appearing on the one below. In his head, he counted the number of floors that he passed for. He needed to do it to get into the one that he needed.
'Just as I thought, the other places where there aren't cities within are not destroyed. Jomurgand shook this place by doing this huge tunnel on the ground, but that's all. Also, people might have been stuck here since the start of the attack. After all, the Teleporting pads probably stopped to work even before the raid began.'
