Moreover, the most crucial aspect is that on this side of the Tianhe Realm, the Great Dao of Life is already claimed.
That claim belongs to the Heavenly Sovereign.
It is possible that the Heavenly Sovereign has already mastered the control of life and death, refining the Innate Life and Death Great Dao.
It is for this reason that Chen Mobai does not want Qing Nu to waste her efforts. However, the Great Dao of Life is the most useful Great Dao for a cultivator, because once mastered, it can absorb the vitality of the Great Dao. Even if it does not achieve immortality, it can still extend one's lifespan several times over.
If one reaches the realm of the Big Tree, of the Sixth Rank realm, they can continuously refine the power of the Great Dao of Life. As long as one does not experience tribulations, they are essentially already immortal.
