It is a common magic technique of the Devilish Dao used to refine and transform souls.
Background[]
The “Soul Refinement Technique” was a notorious, fear-inspiring magic technique in the cultivation world. Some cultivators would even swear death-oaths under threat of this wicked magic technique.[1]
All of the sects and great clans (at least those of the Heavenly South) have specialists that would learn this technique in order to deliver the harshest of punishments to set an example for traitors. This practice had gained it much infamy due to the cruelty involved. It was said that practitioners of this technique were capable of extracting one’s soul and using specialized magic techniques to torment them. Rumor has it that direct suffering inflicted on a soul for even a short moment was unbearable even to those with adamant wills. Furthermore, the stronger the cultivator’s soul, the greater suffering they would feel. These gruesome details would cause cultivators’ faces to pale when they spoke of them.[1]
Rumors of the Soul Refinement Technique have spread all across the cultivation world. The best known among them was the rumor that cultivators capable of the Soul Refinement Technique were able to cultivate a “Soul Tool”, a tool inseparably linked to their own souls. Only with such a magic tool would the user be able to fully utilize the Soul Refinement Technique and damn the target’s soul to suffer a fate worse than death.[1]
Not many cultivators had personally seen a soul tool, but it was said to release a dense, sinister and ghostly aura. Its description closely matched the appearance of the “Soul Congregation Bowl”, a magic tool that had held the souls of over a hundred cultivators.[1]
To demonstrate the fearful reputation that this technique held, early on, when Crooked Soul was possessed by a core formation cultivator from the Controlling Spirit Sect and was subsequently cornered by Han Li, as Han Li took out his alms bowl (Soul Congregation Bowl), Crooked Soul mistakenly believed that Han Li was capable of using this “soul tool” to perform the dreadful “Soul Refinement Technique”. While Han Li meant to integorate him using the the dark, icy qi of the alms bowl, Han Li took advantage of his misconception.
