Xiang Beifei, based on the known clues, roughly speculated his grandfather's plan to revive the Human Race.
The Human Race couldn't survive in the Edge Corner Airspace, so he and Daoist Qingyang planned for humanity's future by migrating humans to the Great Desolate Realm.
Daoist Qingde first utilized the ancestral artifact, the Great Cauldron, to protect every human from the influence of the Heavenly Dao in the Great Desolate Realm, allowing them to live freely there.
Then, let the Human Race begin their cultivation from the Qi-Controlling Realm in the Great Desolate Realm, and when the talents of humanity reached the Heavenly Connection Realm, take them to the Edge Corner Airspace to cut the Dao and step into the Immortal Realm, cultivating more Immortal Realm masters this way.
If their talent was poor, they would live in the Great Desolate Realm until old age, no need to return to the Edge Corner Airspace.
