The General holding the small town was too conceited, believing the establishment of vibration detectors and explosion devices underground surrounded by reinforced concrete would prevent Beastman's burrowing beast assault. However, this method was already outdated; the Beastmen had already found a way to deal with it. Therefore, they unknowingly carried out the frog jumping tactics, and a group of assaulting soldiers led by the mad female orc and the guard team appeared on the supply road between the base and the small town.
The Beastmen were all impulsive. They never thought about trapping the enemy and exhausting their supplies before slaughtering them. The war had been going on for decades, Her Majesty the Queen and highest military commander, General Lamb, had already become impatient to eradicate humans. They wanted to become the only rulers of this planet.
