The Minor Zen School is a lineage created by Humans.
It was created on five islands outside of Dongting Lake by Humans. It could be considered a powerhouse of the Human race. of course it is nowhere close to giants like the Dongting Lake and the Exquisite Valley.
The School had a half of a map which was brought by one of their female ancestors who used to be part of Undying Gate. However, no one was able to determine its use and it was considered useless. Su Yonghuang borrowed the half of the map.
