Davis learned a few Battle Techniques before, some that even uses his Soul Forging Cultivation. Except they couldn't be called Battle Techniques, but Supporting Techniques, also called as Soul Technique or Arts in some regions.
The Soul Techniques he chose were known as Dark Concealing Shroud Art, Soul Suppression Art, Sacred Mark Art, and Unholy Brand Art.
Dark Concealing Shroud Art is a Low-Level Sky Grade Soul Technique. It is used to conceal a person's presence, energy, and soul aura using soul force. The soul force exhaustion is minimum, especially at night since it is dark attributed.
Davis would have been only able to use this support technique if he had cultivated in a dark-attributed Soul Cultivation method, but fortunately, he had his Death Book, which emits a unique dark and evil-like energy which actually is compatible with the technique. He learned it when he tried to practice it.
Soul Suppression Art is a Peak-Level Earth Grade Technique. As the name implies, it suppresses the target's soul, causing the target to face heavy pressure. If the target is weaker than the user in Soul Forging Cultivation, then the target will not be able to make any movements at all, at least, in theory.
But if the target is stronger than the user, then the technique will provide a suppression effect depending on the target's cultivation level.
When Davis found these two support techniques, the Sacred Mark Art and the Unholy Brand Art, he was shocked. These two arts were soul techniques that can be used to brand a person's soul, making that person into a Soul Slave.
Even though the name Sacred Mark Art sounded righteous, it was no different than Unholy Brand Art.
These two Battle Techniques, also called Soul Techniques, needed a person to cultivate either a light-attributed or dark-attributed Soul Forging Cultivation Manual.
Davis decided to train in both since he had both the light and dark attributes from his Sacred Luminance Mist Soul Forging Cultivation Manual and the Death Book, as well as for various reasons such as being able to throw his opponents off-guard since it took only some of his time.
