The City God was a byproduct of the cultivation dynasty after the spiritual qi recovery.
At that time, in the cities of the world, other than the "Yang Official" who handled mortal affairs and ruled over a region, every place also had a corresponding "Yin Official" who was specially responsible for the Netherworld affairs of a region.
This Netherworld was not the land of reincarnation or the underworld, but a world that mortals could not see.
Among them were the spirits in the mountain and the ghosts after death.
It could be seen how ambitious the cultivation dynasty was at that time. Not only did they have to care about the living, but they also had to rule the dead and demons.
The City Gods of various places were basically not conferred to living people. They were all demons, spiritual beasts, and loyal cultivators who were willing to submit to the dynasty and die for the country.
