The Southern Demon Sect's greatest specialty was using Secret Techniques to refine various Celestial Demons into Divine-Demonic Avatars. The Powerful White Bone Demon was one of the most outstanding of these Divine-Demonic Avatars.
However, these avatars required the implantation of a Cultivator's Sub-Soul to fully unleash their power and eliminate the risk of a backlash from the Celestial Demon within.
But a Cultivator's Divine Soul is ultimately finite. Even upon reaching the Nascent Soul Realm, one could not split off too many Sub-Souls without risking the enfeeblement of their Divine Soul.
The Southern Demon Sect, however, found an alternative. To control even more Celestial Demons, they created a unique Demon Sect Secret Technique called the Stealing Fetus Divine Spell.
