The innate abilities possessed by the main body were also present in the Demonic Body, and thus, the innate abilities Rebirth. From the second Demonic Body onward, they were all fully developed.
However, the Rebirth of innate abilities was useless for the Demonic Body. Chen Fei's method of absorbing the Demonic Body involved directly advancing the stagnated proficiency of the Six Desires Demonic Separation.
Normally, once the proficiency of the Six Desires Demonic Separation reached a certain level, it stopped advancing unless the Demonic Body was consumed, in which case the proficiency would continue to grow.
Chen Fei reversed this process by advancing the stagnant proficiency, causing the technique to believe the Demonic Body had failed, so all the essence flowed back to the main body.
The essence of the Rebirth innate abilities, entrusted in the void, was composed of essence itself, which the Six Desires Demonic Separation automatically devoured.
