This world is not a complete remake of the current world map that Zhao Changhe knows. For example, there are differences in places like Beimang and Ancient Sword Lake, but most of it remains the same.
Different oceans and monsoons, different mountains and rivers, different plateaus and valleys can cause completely different climate distributions, greatly affecting species and culture. Given such similarities to ancient China, the geography must be very similar.
The geography beyond the Northern Border to the north is also like this. There may be small differences, such as the rocky mountains of Xuanwu Secret Realm and Xuanwu Lake at Yellow Sand Market, but the overall distribution remains unchanged.
