Of all the Martial Arts Shu Feng cultivated, the Sun and Moon Scripture was the most compatible with the Yin Yang Qi Finger. By using the Profound Qi from the Sun and Moon Scripture, he could easily unleash this incredibly terrifying Divine Technique.
Within the Bi Yao Demon Sect, the Jade Wave Demon Technique was a Yin-Attribute Demonic Cultivation Technique and was not compatible with the Yin Yang Qi Finger.
Of the Bi Yao Demon Sect's two great Sect's Demon Techniques, only the Ten Thousand Gu Demon Technique was truly compatible with the Yin Yang Qi Finger.
Once the Ten Thousand Gu Demon Technique reached the Minor Achievement Realm, the Lifebound Gu within one's body would gain the terrifying Ability of Profound Qi Transformation, able to freely convert the body's Profound Qi into Yin Yang Profound Qi.
Of course, the Yin Yang Profound Qi produced by ordinary Lifebound Gu was far inferior to that produced by a Top Level Divine Skill like the Sun and Moon Scripture.
