"Honk!"
Hundreds of kilometers away, soldiers in many monitoring rooms heard the sound. Those who had been slacking off hurriedly snapped to attention, their eyes turning to the screens.
There was... nothing!
Even the computer AI showed no reaction.
Of course, some superpowers acted directly on the soul, beyond the AI's ability to detect, so humans did not blindly trust the computers' judgment.

"I heard it too. How about slowing down the surveillance footage?"
