"Kill!" They realized that regardless of whether the undead had achieved their objectives, they currently had the main force of that organization barricaded outside the Ancient Ruins Space. As long as they exterminated these enemies, they would not have to worry about their own safety for a substantial period of time given that the organization would be unable to infiltrate the Ancient Ruins Space.

If the monsters left in the Ancient Ruins Space were to collaborate with the organization outside at that time, all their hard work would be in vain.
