Doesn't this mean that in the future, as long as one can cultivate to the Ninth Grade Annihilation Realm, they can reach the Sage Realm risk-free with the help of Saint Gu?
Especially those tributor who are already in the Ninth Grade Annihilation Realm.
Most of them have root bone talent that isn't enough for them to break through to the Sage Realm. Even if they've forcibly cultivated to the Ninth Grade Annihilation Realm Perfection, they know they cannot survive the heavenly tribulation. Their original fate should be to wait until their lifespan is near its end and attempt the tribulation, with the hope that among a hundred people, one succeeds!
Getting Saint Gu's assistance to break through to the Sage Realm, though it means there is no further space for progression and they become the weakest within the Sage Realm, it's still much stronger than the Ninth Grade Annihilation Realm, and their lifespan increases significantly!
