But it's precisely because each raid into the Otherworldly realm is conducted by only a small number of elite teams, that once an accident leads to the annihilation of the entire team, it actually causes a considerable loss to their own Plane.
After all, the members of the elite team are usually cultivated with an immense amount of resources. So even if it's not a total wipeout, just having significant casualties is a considerable loss for their Plane.
As for the Plane where the Bat Monsters reside, the reason they dispatch large numbers of low-level Bat Monsters into the Different Dimension for plunder each time the Plane Channel is opened, is not because their ranks lack individually strong fighters.
Instead, they rely on those powerful individual Bat Monsters to fend off elite teams sent by other Planes to invade their Plane.
