This Body Tempering Technique of Chen Fei's truly counted as an Epic Transformation.
At the level of Dragon Elephant Return to Ruin, no such technique had ever appeared in the entire history of the Ruin Realm. Cultivated to its peak, it could grant a fleshly physique surpassing that of a Dao Ancestor.
Dao Ancestors were the beings with the strongest physiques in the entire Ruin Realm, because their fleshly bodies had received the reinforcement of a Powerful Heavenly Dao, making them far stronger than the physiques of other Ninth-Order peak cultivators.
However, once a Dao Ancestor's physique reached this level, it was basically already at the peak of the Ruin Realm. Whether it was a Dao Ancestor with one Powerful Heavenly Dao or a Dao Ancestor with three Powerful Heavenly Daos, the difference in their fleshly bodies was negligible.
At most, the Dao Ancestor of the Power of Heavenly Dao would certainly win by a margin in strength, but that was bestowed by the Heavenly Dao's Traits and had little to do with the level of their physique.
Perhaps, in the long river of the Ruin Realm's history, there had been Supreme powerhouses who wanted to create this kind of Body Tempering Technique that surpassed a Dao Ancestor's physique, but perhaps after cultivating it to the end, they discovered it was simply impossible to continue upward.
Human strength had its limits, and even Supreme Realm powerhouses were no exception. Without the reinforcement of a Powerful Heavenly Dao, a Ninth-Order Peak Physique was the limit, let alone surpassing the strength of a Dao Ancestor's physique.
If the technique Dragon Elephant Return to Ruin were taken out and given to other Ninth-Order Supreme Realm cultivators to practice, they could only cultivate it to the Ninth-Order peak. There were far too many barriers
