The leader finished the first barrack and moved to the second one.
Similar things are happening in different spots.
But one of the unit members is standing on a large tree with his red metallic bow as he shot arrows.
They are silent and not flashy at all. But as soon as they landed at different spots, the arrows exploded and threw some kind of liquid into the surroundings which then immediately turned into raging flames that looked like they came straight from hell.
The whole camp that just went peaceful suddenly became an inferno with screams and smells of people burning to death.
But the Fire unit didn't show any expression. In fact, they didn't even show their face. Their face is covered with a mask and they are killing and burning everything alive and dead.
The camp organizers and the leaders are all alerted by then and started running toward the troublemakers.
