For example, Lu Yuan, currently residing in Mi Yun Mountain, has after thousands of years of expansion, already occupied one-third of the territory of Youxin Country.
Of course, his Immortal Sect Daoist venue is definitely not a place where ordinary people can enter at will.
Thus, this one-third of the area has become unreachable for ordinary people.
The various sub-courts under the Taiping Tao Sect, although not as extensive as Mi Yun Mountain, have essentially claimed one-tenth of the area where they are located.
This is just the recently risen Taiping Tao. One can imagine the degree of territorial encroachment in the Immortal Realm.
For other old, established Immortal Sects, this kind of encroachment is even more obvious.
Just from this point, at least one-tenth of the Immortal Realm's territory is exclusively occupied by various Immortal Sects and cultivators.
