Dust Technique, profoundly mysterious. Once concealed, even the Divine Spirit Soul Force of a Divine Refinement Celestial could not search it out.
If Wen Yong had cultivated the Dust Technique, his chances of escaping would have greatly increased.
However, what saddened Xu Yan was that he had only taught him a little about the Dust Technique when Wen Yong appeared utterly confused, not knowing how to cultivate it.
At that moment, Xu Yan realized that the Martial Arts he cultivated were different from Wen Yong's, and Martial Arts from the Spiritual Realm might not be suitable for the Dust Technique.
Thus, Xu Yan did not impart the remaining methods of the Dust Technique; instead, he pondered a reduced or simplified version of the Dust Technique to teach Wen Yong.
