At this moment, Dong Tianyu, hovering in the sky, saw the situation on the ground right away. Although he was fifty meters above the ground—a distance even a school child could step over—the skeletons' leg movements when marching forward were not large. Hence, many of the skeletons would essentially be tripped by the Blockade Rope.
The majority of the skeletons, even when they fell, could quickly get back up from the ground. However, for some that had just emerged, their physical strength was not yet very high. An abrupt fall could likely result in fractured bones or even broken arms or legs.
As only the ordinary skeletons would be this affected, their bone repair speed was not very fast. Because they lingered in place to fix themselves, they moved beyond the coverage area of the white fog, exposing them to the sight of Dong Tianyu and the drone.
