An Underworld city established by Kampala, Guli, and Jiang Zheng.
The city wouldn’t lose against any great Human city.
Its walls were made of stone. However, the adhesive used to paste them together wasn’t cement nor mud, instead it used a bloody red soil that had a strong bloody smell.
The city wall was about 20 meters high with a gate that was 20 feet wide and ten feet high. The gate was made out of bones and looked horrible.
Zhao Hai still can’t feel the total length of the city wall, but he reckons that it should be more than 10 thousand meters.
