Following the success of the trailblazers, more squads were sent out to the Lost Continent to create and man the outposts. By now, there are at least six federal outposts on the Lost Continent; each one was created without alarming the demons roaming the lands.
Of course, this operation wasn't completely silent. There had been times when some squads were unlucky and were met with aggression from the demons who sensed their movement. The way they solved this issue was simple, though: kill all witnesses. It doesn't matter whether they're stray animals or not; as long as they see humans on the Lost Continent, they must die. And the soldiers gave them thorough deaths too. After all, they couldn't risk allowing the demons they killed to be reincarnated, only to inform the entire demon race about this operation.
