After learning about the Sin Devils, Liang for some reason chose the Unholy Soul Refining Scripture as his main soul cultivation method. However, he also recognized the value of the other two techniques and decided to study and integrate them into his own techniques. He believed that by successfully combining these techniques, he could reach new heights in his abilities.
Liang planned to integrate the Soulfire Incantation into his Infernal Void Flame Art, the soulfire would probably help him in cultivating the third stage of Infernal Void Flame Art-Flame Fusion.
Likewise, he intended to incorporate the Shadow Essence Veil into the shadow techniques of the Oblivion Sword Manual, using it to deepen the shadows' concealment and deception.
