After hearing the roar of the aircraft, the Black Hand Master did not move.
He did not even activate any of the prosthetic body functions that were not in normal operation.
— Stay calm, stay calm...
That was how the Black Hand Master admonished himself.
Even if there were sounds of departure, it did not mean that those people had truly left.
In this era, one could simply place a camera on the spot and observe this place from a distance of a hundred meters.
If one was willing to use several repeaters, that distance could be extended to faraway places, possibly several kilometers.
Conversely, without even considering the core of the Earth, sniper rifles had a range of several kilometers.
These were not ancient times where one could come out at ease after seeing people leave.
The Black Hand Master even forced himself into sleep once more.
Now, nothing else mattered.
