Becoming an Immortal signifies entering the Heavenly Human Realm within the Great Luo Heavenly Star Domain.
Stepping into the Heavenly Human Realm is also known as Feathered Ascension, entering the Immortal Realm, transcending mortal existence.
This Nine Heavens Flames, as recorded in ancient texts, can only be surpassed by the heavenly beings.
Thus, over the millennia, only those Immortal Lords have left the Nine Domains and ventured into the outer cosmos.
Other beings, like True Emperors and Ancient Emperors, could not leave the Nine Domains.
But now, the Nine Heavens Flames have weakened.
Chu Fengmian looked, and now these Nine Heavens Flames even True Emperors could not withstand.
Even some powerful Six Tribulations True Emperors, some quasi-emperors aided by external forces, can now break through the Nine Heavens Flames and enter.
It seems that during the time Chu Fengmian was absent from the Nine Domains, something major must have occurred there.
