"Then why don't you make it smaller?" if compressing it would do such magic, then why wouldn't we make this hole like a needle hole?
"That size is the perfect size for the orb to bring the most effect without endangering the life span of the orb," he pointed at the orb before adding, "if we tried to compress it even further, the orb itself may crash. If not, the time for the den to last will be shortened."
"These orbs produce dens with life limits?!" I was shocked to hear that.
"Nothing we make lasts forever, lord," Loran acted as if he was a wise old man, "the lifetime of any single orb we have will last for a month at most. But if we compress it more, the time will decrease even if it is only a few days."
"Interesting…" I never thought these dens would last for one month and vanish. Thinking about this made me feel more secure and a little disappointed.
If this was the case, then there was no point in worrying about zombies coming out from these dens going berserk.
