An ordinary fairy came to the mortal world and started infrastructure construction in Nanxing Mountain.
Slowly, more and more people who are destined to enter Nanxing Mountain become permanent residents who can come and go freely.
Nanxing Mountain is a very warm place with many interesting people and stories.

…
The barrier set up by the Nan family finally allowed Nanxing Mountain to last for ten thousand years.
