After Donghuang the Great and Emperor Yeqing united the Divine Prefecture, many people began to follow their trail. A lot of people knew that Donghuang the Great and Emperor Yeqing spent some time in the Eastern Barren Territory during their upbringing, which was why so many wanted to step into the Eastern Barren Territory. However, the two emperors put out a ban stating that non-native Sages were not allowed to enter the Eastern Barren Territory.
They had united the Divine Prefecture and were peerless existences. Who would dare to challenge the ban? Even to this day, there were many who didn't quite understand the reason for the emperors' ban. Despite this, there still many people who followed their footsteps in those days. Naturally, they all knew about Sky Mountain, but no one was ever able to reach the top, especially Nobles.
