The Demon Region was not a territory with only a single region.
The Divine Realm had a thousand regions. While the Demon Region occupied roughly one-fifth.
The remainder four-fifth consisted of regions for humans.
Of course, human regions had quite a number of demon race experts too. But to the dragon clan and the white tiger clan, this sort of clans, they basically could not be seen in human territory.
Ye Yuan reckoned that White Light might have awakened some inheritances memories and had compelling difficulties, that was why he would leave without saying goodbye.
Being informed that White Light left, Ye Yuan could not help feeling somewhat lost.
This goodbye, no idea what year and what day could they meet again either.
Ye Yuan was quite worried for White Light too. After all, he was only at Tier 6 right now. Wandering around the Divine Realm was still a little too dangerous.
