Hun Changqing could feel that strange yin-yang energy stirring his incomparably pure Supreme Yin True Qi, circulating through his body and limbs along a route he had never seen before.
Once that energy completed a circuit through his body, it actually left him and flowed into Gu Xun'er, following the same route through her body and cycling endlessly between the two of them.
"What is this... some kind of dual cultivation art?"
Shock and suspicion surfaced in Hun Changqing's eyes. He simply could not understand why the Dou Qi Continent possessed a dual cultivation art of this caliber, one capable of forcibly mobilizing his Supreme Yin True Qi and making it cooperate with Gu Xun'er's energy to circulate along a prescribed route.
Indeed, Gu Xun'er was currently practicing the dual cultivation art exclusive to Supreme Yin and Supreme Yang: the Yin-Yang Mysterious Feminine Music Fusion Art.
Those familiar with dual cultivation understood its benefits. Not only could it offer bliss comparable to ascending to heaven, it could also rapidly increase one's strength, benefiting both participants.
However, that required both participants to link their minds and practice the art together. If only one of them knew the formula, the other's experience would not be nearly so wonderful.
Hun Changqing, for instance, lacked the corresponding cultivation instructions needed to coordinate with Gu Xun'er. He could only passively circulate his energy according to her will. At that moment, he was nothing more than a puppet on strings, and the ordeal was excruciating.
Thus, the energy containing both Hun Changqing's and Gu Xun'er's power continued completing circuits through their bodies. Yet compared with its gentleness and docility inside Gu Xun'er, it ran rampant and tyrannical inside Hun Changqing, leaving him entirely incapable of thought.
He felt as though his entire being was falling apart.
