One month was a pretty long time. The leaders of each camp had to clear the regions in the area to prevent monsters from increasing their territory. Some of them even had to cultivate lands and kill monsters for their meat, after all.
"Why one month?" Alissa asked.
"One month isn't a shor period, but isn't that long either," Isis replied. "The demons should know that we are planning something, but taking our time will make them realize that we aren't confident in our preparations. That will make them drop their guards, once that happens, we will swiftly defeat the four remaining demon generals… if we all agree that we have enough strength to do that and face the next three."
"One month should be plenty enough time if we use Void World," Daniel said. "If thousands of survivors use Mana Stealer on the same enemy at the same time, I would bet that we can stop any creature."
