Jiang Yuebai learned many things about Ao Juan from Zheng Yougong. Originally, she was thinking of going to the West Sea, but Zheng Yougong said that the western region of the Green Dragon Realm, with the Fulong Mountain Range as the boundary, is inaccessible to outsiders.
Even cultivators wanting to help resist the Dragon Clan can't come and go freely. They must go through identity validation from Biyou Palace and the Fulong Sect.
Moreover, after entering, one must stay for at least ten years to apply to leave.
He also said that this rule wasn't there before; it started being implemented five years ago, all because of the Winged Dragon.
It's said that the Winged Dragon once brought some of the Dragon Clan's experts, disguised as Human Clan cultivators, trying to sneak through the Fulong Mountain Range to wreak havoc in other regions of the Green Dragon Realm.
