If the Plane Will were not dormant or had selected a spokesperson to manage all affairs, then even if the people from otherworldly realms wished to sacrifice lives in exchange for information, they might end up receiving false intelligence.
They might even deliberately provide coordinates to dangerous zones, or offer the locations of pre-set traps as coordinates to the others.
However, the planes where the Plane Will is awake or has selected a spokesperson are essentially advanced planes; for the majority of planes like Blue Star, the Plane Will remains in a state of slumber.
Thus, under normal circumstances, the sacrificial method used by creatures like Bat Monster would usually yield accurate coordinates.
The method used by Bat Monster, an otherworldly being, to search for treasures does not work for the humans of Blue Star.
