The Special Operations Team stormed all the way to the door of Duan Zhiyi's room without suffering so much as a scratch, let alone any deaths.
Notably, as they approached the door, the surviving drones under Duan Zhiyi's control seemed to unleash their hidden potential. Their agility and coordination improved dozens of times over, if not more. They swooped and darted through the air, dodging and concentrating fire, giving the Special Operations Team quite a bit of trouble.
Of course, this was not some sudden power-up on Duan Zhiyi's part. Xia Xu, who also possessed brain-control technology, knew what was going on.
Brain-control technology only read the "meaning" of brain waves; it could not send information back the other way. As such, there was no way to receive information from electronic devices directly through the mind. Video and audio recorded by drones still had to be received through the eyes, ears, mouth, and nose.
But human sensory organs had their limits. When controlling drones remotely, one could only watch their footage on an electronic screen. At best, one could use smart glasses like Pan Yuanhang. Even something more high-tech would merely project images onto the retinas or the like.
This posed no problem when controlling a single object, but the flaws became apparent when controlling several.
For instance, remotely operating multiple drones required switching back and forth between their camera feeds, making precise control naturally impossible.
Even stitching all the feeds together would not help much. Human perception itself had flaws: attention and visual focus could only concentrate on one point. Without exceptional talent or extensive training, it was difficult to divide one's attention and process multiple streams of sensory information with precision.
However, if the drones being controlled were near the operator's body and within sight, the situation could
