Shalltear's declaration was undoubtedly an unshakeable death sentence for the natives of this world.
As the Guardian of the first to third floors of the Nasalik Underground Tomb, designed by the Supreme Sovereign "Ainz Ooal Gown" himself, the power of Shalltear Bloodfallen, a level 100 NPC, was calamitous to this world.
When she began her slaughter, let alone mere humans, even the dragons which once ruled this world, unless they were of dragon sovereign status, were no different from fragile dolls in her presence.
As for things like Heroic Domain or otherwordly domains, they were practically jests before this being.
In front of the fully leveled Shalltear, what difference was there between the so-called Heroic Domain of level 29 and above and an ordinary villager?
This mountain of corpses and sea of blood was the evidence.
No matter how many thieves or how large a party, in the eyes of a true monster, they were merely prey that could be hunted for sport unilaterally.
