Inside the sovereign immortal aperture.
Mini Western Desert.
An enormous pitch-black city occupied the desert.
This was a large city with rigid structure. The entire city was a hexagon and its walls had gone through the weathering of time. The city walls were more than two hundred li long, they were a hundred feet tall and tens of feet thick.
If a person stood on the grassland, they would see what looked like a huge black beast sprawling. If they got closer, they would need to raise their heads to look up at the huge city gate and walls.
Every edge of the city had defensive towers that were filled with countless holes that could shoot out arrows.
Every few li apart, there would be a wide path for horse carriages to move on.
There were even very secretive armories within the city walls.
Passing the city walls, one would arrive at the vibrant world within.
