The shooting range between Devil's Castle and the other four castles was a hundred meters. This was meticulously designed. An ordinary thief wouldn't bring a sniper rifle; it would be too much trouble. They only carried easily concealable handguns.

But this was only true for ordinary thieves. It was useless against Wushuang.
