Almost discovered...
On the 10th floor of the Lost World, Hoenheim, wearing an invisibility cloak, hid under a twisted piece of metal debris, letting the demons above fly over.
His invisibility cloak was extremely effective, any light shining on it only revealed the scenery behind it. It also isolated sound and dust,
and combined with his well-hidden aura,
the demons passing by did not notice a human from Earth hiding among them.
Finally, they moved on.
The flying figures of over a dozen demons grew more distant. Hoenheim took out a liquid crystal panel from his backpack, glanced at it briefly, and then returned it to his inventory to prevent electronic signals from drawing the demons' attention.
Many people from the Bell Tower were also kidnapped, some of whom were still emitting location signals.
