Batman slowly made his way forward through the dark sewers.
Before leaving the sewers, he had to scout the area. Just as he had said before, Bat-Cat could not possibly have set up a surveillance network covering all of Gotham without a single blind spot. That was nearly impossible.
If Batman had been given ten or twenty years, it might have been possible. But according to Croc-Cat, Bat-Cat had only been here for four or five years. More than half that time had been spent remodeling the city, so the current surveillance network was bound to have plenty of gaps.
By poking his head out from beneath manhole covers and observing the surroundings, Batman gradually drew a map of the cameras' patrol routes in his mind.
After roughly completing the map, he discovered a modest but significant flaw in the patrol routes.
From the ground, the patrol route seemed nearly flawless, with almost no openings to exploit. Yet one set of cameras, during a certain period, failed to adequately inspect the ground—or rather, the area around the manhole covers.
That was interesting. Batman knew it did not exactly count as a flaw, because if it had been him, he would also have prioritized monitoring building rooftops and terraces over the unremarkable ground. Between the two, high ground was naturally more important. Elevated positions had always been crucial in any strategy.
Still, it was as though the opening had been deliberately left for Batman, allowing him to move safely onto the surface through that gap without being discovered.
Even more coincidentally, the flaw in the patrol route appeared in the dead of night, allowing Batman to use both his fur color and the darkness as camouflage to safely reach the surface.
Batman felt that it was all too coincidental, as if
