As a Dao Ancestor of a realm, just how abundant one's wealth could be was something ordinary Supreme Realm cultivators could hardly imagine.
Nan Caiming had been the Space Dao Ancestor for so many years. Although Top-Grade Essence Crystals and Ninth-Order Spirit Materials were already of little help to his cultivation, he still kept a portion of Essence Crystal Spirit Materials on him.
Just this small portion alone was already so vast in quantity that it far surpassed what had just been obtained from killing the evil creatures of the Abyssal Cold Sea.
Moreover, aside from Essence Crystals and spirit materials, Chen Fei was currently holding a portion of spiritual essence in his hand—a portion of spiritual essence left behind after a Dao Ancestor had fallen.
Of all Chen Fei had learned, only Dragon Elephant Return to Ruin had yet to reach Great Perfection. Everything else had already stepped into the Great Perfection Realm. As for Heavenly Dao Authority, there was also only one—Space Heavenly Dao.
With the Dao Ancestor's spiritual essence plus the Essence Crystal Spirit Materials before him, taking control of the remaining Authority of the Space Heavenly Dao would definitely be more than enough. When that time came, Chen Fei would also directly step into Ninth-Order Peak and become a true Dao Ancestor of a realm.
But whether Dragon Elephant Return to Ruin could be cultivated to the Great Perfection Realm, Chen Fei felt somewhat uncertain. The remaining portion of Dragon Elephant Return to Ruin was far too difficult to comprehend.
The further he went, the more Chen Fei felt his comprehension was insufficient. Even after plundering a portion of Nan Caiming's aptitude just now, Chen Fei did not have much confidence at this moment.
A cultivation technique like this was simply not prepared for Ninth-Order cultivators.
