The place where the Imperial Heaven Realm descended was actually not in Jiangnan Province, but in Hannan Province.
It's just that Hannan Province ranks among the bottom in the Forty-Nine Provinces of Great Zhou, and the people from the Imperial Heaven Realm somewhat looked down on it, so they migrated to Jiangnan Province.
In terms of geographical location, Jiangnan Province is very far from Shengjing City in Beiyuan Province. The Imperial Heaven Realm doesn't want to have any conflicts with Great Zhou just yet, maintaining a clear boundary is better.
Moreover, in Jiangnan Province, martial customs flourish and resources are abundant. This province definitely ranks in the top five among the Forty-Nine Provinces, only such a place is worthy of the Imperial Heaven Realm.
Most importantly, in Jiangnan Province, the Imperial Heaven Realm found no force capable of threatening them.
