After Yuan Chiyi entered closed-door Foundation Establishment, Chen Mobai asked E Yun about the secrets of the Divine Tree Mystic Realm.

"This is a secret passed down orally within our Divine Wood Sect. Now that you've reached Foundation Establishment, there's no harm in telling you."

"The Divine Tree Mystic Realm is said to have been left by ancient cultivators. In the past, Yuan Zhenjun entered it and took away the greatest opportunity. It should have collapsed and disappeared."

"However, Yuan Zhenjun pitied all beings and felt that he should give future cultivators a chance. Thus, he spent great effort transplanting three divine trees, connecting them to the ley lines of Giant Wood Ridge, reinforcing the mystic realm, and leaving behind an entrance that could be opened."
