With the command given, countless fireballs suddenly erupted above the valley, falling like meteors and instantly turning the valley below into a sea of fire. Amidst the flames came a piercing squeaking sound, as if countless rats were struggling in agony.
Outside the flames, the soldiers of the United Army gripped their weapons firmly, poised for action.

"These rats are trapped now! Second and third rapid response units, advance to the River Source Battlefield immediately!" The commander's voice echoed through the valley.
With the order given, some mounted soldiers of the United Army and Night Watchers swiftly broke away from the battlefield and galloped towards the distance.
