In the Cultivation World, there's a legend that when someone's comprehension of the Dao reaches a certain level, Innate Purple Qi will appear.

In ancient times, the Cultivation World was rich in spiritual energy, and people back then had no concept of ascension.

In the center of the Central State, there was an ancient tree that reached the heavens, connecting to the Immortal Realm. As long as one's strength was sufficient, they could pass through this channel and directly enter the Immortal Realm.

Similarly, powerful beings from the Immortal Realm would occasionally descend to this world.
