According to Tawell's research, reversing the Abyssalization of Fallen Apostles or similar higher lifeforms that had undergone Abyssalization—such as fallen God Race members—was limited by their energy levels, or rather, their resistance levels. The more powerful an individual was, the stronger their resistance would be after Abyssalization, because any normal living being had an instinct to maintain its current state of life. On the side of order, they resisted the Abyss; on the side of the Abyss, they resisted order. To shift a powerful unit between these two states required far more effort than converting an ordinary unit. If you wanted to purify a group of ordinary Fallen Apostle soldiers, you only needed to connect them to the New Empire's Spiritual Network—naturally, a local network dedicated to purification, to prevent their Abyssal Aura from interfering with others on the network. Since Void Creatures were connected to the network, ordinary Fallen Apostle soldiers could quickly be reversed. But converting a leader-level Abyssal creature was much more troublesome. Silvia had remained connected to the Spiritual Network for a full year or two before the Bellavella personality within her awakened in a normal state. Viska had fought me until the heavens went dark before she remembered who she was. Pandora had nearly fought Viska to death before I purified her in a short time. As for the Fallen Apostle commander before us, it took fifteen minutes of a father-daughter double beating from Xiao Xue and me before his eyes finally cleared...
Before I figured out a more efficient method of reversal on my own, the purification Benevolent Fist was probably the only thing capable of controlling the Abyssal power within high-ranking Fallen Apostles. And judging by Xiao Xue charging in with her fists swinging, I apparently still hadn't developed a more efficient method
