It was a pretty simple solution he came up with to be fairly honest. All he did was slowly release pressure in the surroundings, and check where the pressure got disturbed.
This required heightened concentration, but he quickly had the other two Rulers defend him, while he just stood frozen in place trying to do what he had to.
After all, he would be quite vulnerable during the time, so he had to make sure that nothing untoward happened towards himself while he tried to locate the rat.
With those thoughts in mind, he didn't waste any second more as he got to work. Of course, all the experts around them had to stand on their spot frozen, and no one dared to make a move.
Unfortunately, despite the great idea, it seemed like it was useless, as he wasn't able to find even a shadow of the rat, not to mention the rat himself.
This was extremely disappointing and enraging, but he didn't give up, there had to be something, there had to be a trace.
