The beast God city was the Holy Land in the hearts of all the orcs. It was made from the soil of the grasslands, withered grass, and mud. The water used to make the mud was not ordinary water, but the blood of various magical beasts raised in the grasslands, so it was called beast blood soil.
And because the grasslands also lacked wood, orc city used magic beast bones instead of wood. It was because of this that it was called beast God city.
It was said that in order to build the orc city, all of the orc tribes had to live frugally for decades, using who knew how many magic beasts.
That was the Holy Land in the hearts of the orcs. The location of the beast God city was not far from the northern ice fields. The orcs believed that the orcs had defeated the demons there, and that was where the orcs had become today. Therefore, they built the beast God city there to commemorate the beast God.
