Ziyi led Qingfeng and Tiangang into a hidden valley.
This valley was hidden under the cliff, so without Ziyi, Qingfeng and Tiangang would never have been able to find it.
In fact, Ziyi was planning to bring two fighters from the Northern Clan to battle with her tomorrow, but she changed her mind once she saw the power of Qingfeng and Tiangang. These two guys were even more powerful than the clan seniors. Right now, she was heading to the Holy Realm instead of going back home first.
In Ziyi's mind, Qingfeng was a monster. He was way stronger than those seniors in her clan.
The valley was, indeed, so gigantic that it occupied thousands of acres of lands. There were also hundreds of houses inside, inhabited by people from the Holy Land. Both people from the North and the South lived there together, but the land was exclusive to the seniors and core children. Regular people wouldn't be allowed to live there.
