In the dim underground city, a massive building had been modified by Amberser into his weapon testing facility.
A drone with four wings smaller than a palm took off from the ground, swiftly flying forward,
Suspended by dozens of ropes, its path segmented, the drone had to make several turns to reach the destination before firing mini crossbow bolts at three targets there.
Calling them crossbow bolts was a bit of a stretch since they were more like slightly longer flying needles.
This drone took a full minute to complete the task over a distance of just over fifty meters.
Though its speed had some issues, overall the completion rate was high, successfully navigating all obstacles and striking the targets accurately at the end.
Amberser then released another small plane made of metal, perfectly designed according to aerodynamics.
