tracks people with a 'scent'

As expected, Fugan Ryuuzou’s tanker truck was attacked within minutes. The situation
was reminiscent of leaving a sugar cube near an ant hill. At first, a few groups began
fighting over it, but they soon realized it would all be for naught if someone called AntiSkill. Once they decided to work together, they used gas burners and high pressure
water jets to disassemble the tank and take away all the gold bars.
The weapons seller who owned the truck had hidden directly below it. It had been a
desperate strategy forced onto him by his inability to move. If any of the men had
glanced under the truck, his death would have been unavoidable.
“…”
Tsuchimikado was on the roof of a nearby building.
He was monitoring the situation using binoculars that could digitally change the
magnification. One of the hyenas may have been keeping track of the time with a
stopwatch because they scattered at exactly seven minutes. Tsuchimikado started
hearing Anti-Skill sirens two minutes after that, but it was of course too late.
(Now then…)
Tsuchimikado took a deep breath and pressed a few buttons on the side of the
binoculars.
He switched the mode over to one that displayed a few glowing bluish-white lines on the
cityscape below. The lines were all straight but took countless turns along the way as if
they were carelessly travelling through a maze. Needless to say, the lines indicated the
escape routes of the hyenas who had taken the gold bars.
Tsuchimikado had added a special “scent” to the gold bars Fugan had collected.
(When things go this well, I start to suspect a trap.)
The hyenas had started fighting when they first saw each other, so they were obviously
not comrades. The different teams naturally used different escape routes.
However, as Tsuchimikado watched on from the rooftop, the scattered groups started to
converge on the same point.
(Just as I thought, someone bigger is secretly controlling all of the hyenas.)
