The situation in the Dahuang Realm matches exactly what Fuxie described: it is a world currently in the midst of a process of "indoctrination."
However, due to various reasons, the people from the Dao Court—who should have maintained a dominant position to educate the masses—somehow ended up integrating into the local hierarchy. They found themselves trading blows with the natives, eventually becoming part of the landscape themselves. Perhaps it was because of the Heavenly Demons, or perhaps due to some other accident. In any case, An Jing would have to wait until he could next contact his master to find out the truth.
"No wonder the Dao Court is always expanding; there are indeed tremendous benefits to it."
