The defenses of the two neighboring countries were relatively weak, so the three Half-Beast armies split into two waves to attack the two Kingdoms. It was finally time to pay back their hatred from before; they had been holding in that anger for so long, and the three armies excitedly attacked the two Kingdoms.
They decided to destroy these two Kingdoms first before turning to destroy the Lelai Kingdom and the other Kingdom.
Even though they did not know why the Lelai Kingdom had done such a stupid thing, it was clearly beneficial to them. What was key was that the Lelai Kingdom could not defend against the three of them, so they were not worried that the Lelai Kingdom would do something to them.
After the two waves of Half-Beasts entered the territories of the two Kingdoms, they pillaged everything in sight, and the two Kingdoms quickly sent their armies to defend.
