Unlike the Red Heart Sect's Ultimate Skill, which focuses on cultivating the physical foundation, the Profound Qi Lifeless Yin Rune places greater emphasis on one's connection to and manipulation of the Heaven and Earth Primordial Qi.
It is said that once this Ultimate Skill is mastered, the Power of the Yin Talisman it generates possesses numerous transformative abilities. It grants a powerful enhancement to the execution of one's own Primordial Qi and Techniques, particularly those of a precise nature.
Furthermore, the Power of the Yin Talisman possesses a quality that makes it exceedingly difficult to defend against, as if it can permeate anything in the world. A Martial Artist who masters this Ultimate Skill wields unpredictable and uncanny methods, capable of harming others unseen.
However, because the cultivation requirements for this Ultimate Skill are rather demanding, its Cultivators often experience various hidden dangers and mutations.
