Before any cultivator ascends from Constellation to Moon Jade, they will try every possible way to purify their own spirit force, reducing the impurities in it to the lowest level.
The purity and strength of the spirit force will directly affect the potential of the cultivator after ascending to Moon Jade.
This is similar to when a cultivator initially opens spiritual apertures in the Spirit Stream Realm; the more spiritual apertures opened, the greater the potential in the future. It might even be the case that if the number of spiritual apertures doesn't reach a certain level, one could be stuck at a certain realm for a lifetime.
Lu Ye doesn't need to purify his spirit force; his foundation is utterly perfect. Thus, what he needs to do is quite simple: activate the Dragon Transformation Method, allowing his spirit force to metamorphose into mana. When the spirit force metamorphoses into mana, that is when he ascends to Moon Jade.
