Southern Border.
The Da Lan Dynasty borders the East Grassland in the east, the Wilderness in the north, the vast sea to the west, and an endless desert to the south.
Initially, there were many small countries and tribes on the desert, but later a legendary king unified them, establishing a unified empire called the Great Desert.
However, as this legendary king passed away, coupled with the Central Plains countries' constant provocations and discord sowing, the Great Desert eventually split into two desert countries.
One with a black flag was called Xuanmo.
The other with a red flag was called Chi Mo.
These two desert countries were conquered over five hundred years ago by the Grand Ancestor Emperor, who led troops to subdue them, and they both bowed to the Da Lan Dynasty, willingly becoming its vassals, offering tributes annually.
After the death of the Grand Ancestor Emperor, although there were some movements in the two desert countries, not many large-scale wars erupted.
