Stepping inside the largest library hidden away within the palace at the very core of the capital without encountering any problems along the way, Xuan Hao didn't waste much time lingering around the outer parts of the library and directly moved towards the deeper sections where the most valuable information would be stored…. And soon enough, he found himself running into a rather unique formation that should have been created in the past when there had once been a skilled formation master amongst those following traditional immortal cultivation.
The only reason why he didn't think it had been constructed by one of the Foundation Establishment Realm cultivators currently within the capital city being that he could clearly sense that the creator of the formation had at least reached the Core Formation Realm when the formation had been created. Impressive by the standards of the ancient secret realm where the limit of cultivation was the Nascent Soul Realm.
