"It will show a large area of red, connecting to every place in the Buffer Zone." The staff member laughed, "This device is only somewhat useful in the desolate wilderness. Once there's a crowd somewhere for too long, it basically fails."
Alright.
It really is quite limited.
Inspectors could potentially detect infection sources every day, bringing the scent inside Shelter City.
Moreover, those scavengers sometimes also come into contact with infection sources, but they are not infected or have eliminated the infection. Relying on such simple signal detection can't even assist in detection at the checkpoints.
Furthermore, the maximum detection range is only two hundred meters.
Cheng Ye glanced around. The yellow signal points mostly ranged from 0.2 to 0.5, with some red points at only 1.1 to 1.3.
