Kunlun Mountain is the center of the Divine Continent, where the capital of the Kaiyuan Divine Dynasty is located. Below it is a vast plain arranged in the Eight Trigrams, with eight giant cities. After several years of development, they have become increasingly prosperous.
The scale of a city is restricted by many factors, the most important being industry and transportation. A huge industrial system is needed to support enough population, and developed transportation prevents the city from being paralyzed.
Originally, the human race was primarily agricultural, and such large cities were impossible. But Zhang Kui broke the monopoly from the top, spreading the cultivation method among the people, inadvertently breaking the shackles of civilization.
