Qingqiu Mountain.
Within Nine-tail King City, there were five major secret realms, each occupied by one of the five major families; only the successive clan leaders knew that there was a sixth secret realm in Nine-tail King City.
This secret realm was known as Qingqiu Mountain. Ancient trees of the barbaric mountain range reached the sky, sprawling for ten-thousand miles and emitting the aura of primal desolation everywhere.
There was no detailed record in the history of the Nine-tailed Fox Clan of how Qingqiu Mountain came to be. According to rumors, this place was originally a mountain range of the Greater Desolation that the first Monster Emperor had intercepted and bestowed upon the Nine-tailed Fox Clan.
At the end of Qingqiu Mountain, passing through the ancient caves, one finds a dim and hazy chaotic space.
