Under the Heavenly Dao, transcendence is not permitted; this is the destiny for all beings, with no exceptions, even for The Three Pure Ones and Nuwa, who attained their sainthood through merit.
Ye Xuan sought an existence where Heaven and Earth could perish, yet he would not; where all things could die, yet he would not die. His only path was to prove the Dao through strength, to truly transcend this realm, and become the saint of all saints.
Now, Ye Xuan faced two choices—he could, like other Daluo Golden Immortals, condense the Laws of Heaven and Earth, henceforth subsisting under the Heavenly Dao and utilizing the power of Heaven and Earth for his own use.
The second path, to carve out his own laws and Dao, to step into the Daluo Realm relying solely on his own strength without borrowing the power of Heaven and Earth, was also the initial threshold for proving the Dao through strength.
