The jade scrolls in the storage bag of the Ape Demon are mostly techniques of the Demon Race's cultivation or various Sword Scriptures, which do not interest Gu Yuan.
Only these two jade scrolls piqued his curiosity.
The Soul Refining and Demon Heart Technique is a Demonic Dao method for cultivating the Divine Soul.
This technique requires gathering a large number of Life Souls, then using a Secret Technique to refine them into a bowl of "Soul-Refining and Spirit-Vibrating Soup." This soup, once ingested, feels like being cut by a thousand blades. The Soul is sliced by countless sharp edges, causing extreme pain, but if one endures it, the Power of the Soul will greatly increase.
If one can endure seven bowls, they can forge a "Soul-Devouring Demon Light," with formidable power. If the Divine Soul Power of a cultivator is slightly weak, their soul can be directly pulled out and torn into pieces with a single strike.
