"Twenty meters?!" A sheriff who was relatively close exclaimed, immediately pulling out his gun.
"At this distance... I should be able to find a way to pinpoint it precisely..." The researcher holding the device walked in a small circle at the spot, and as he moved, the device kept emitting a "beep beep" sound... Finally, the researcher settled on a direction and started walking forward step by step.
The frequency of the beeping increased continuously, indicating that his chosen direction was correct... The distance between the device and the spectral object kept shortening.
Behind the researcher, a group of fully armed sheriffs stood ready, each one trying their best to suppress their breath and heartbeat. The scene was so quiet that only the beeping of the device and the sound of the researcher's boots stepping on the ground were heard.
The beeping became more and more rapid, while the researcher's steps grew slower and slower...
