A large camp a few kilometers in diameter was cleaned of all lives that originally inhabited it. And one wouldn't believe that the grunt of the work was done in the shape of behemoths fighting.
The makeshift arena of the three Level 5 beings had been wide enough to clear part of the battlefield, courtesy both of Mountain intentional actions, and of the lack of care by his two opponents who had been fighting with their lives on the line.
Half an hour, that was the time it had taken to cause hundreds of deaths, and that was the time Mountain's fight had taken. And that was the time that tested the human evolvers who participated in the operation. Because whether they were elites or not, faced with a crowd of aliens they had no means to crush one-sidedly, being alive as they reaped lives was already a feat in and of itself.
