When Bai Zemin returned to the Gales Kingdom, the war against the demons was already over.
It was no surprise to anyone that when King Philip appeared dragging the battered corpse of the demon general Bel'gos the demons immediately lost all spirit to continue fighting against the humans and tried to escape. However, without Third Order demons to stop the first princess and the king it was impossible for these demons to run faster than them.
The corpses of the demons were incinerated using a special method that burned everything except the bones. As for the skeleton of the demons' bodies, Bai Zemin later learned that they possessed a strange quality that helped accelerate the growth of plants and also strengthened the soil for the cultivation of food.
