Resonance between man and heaven was, in truth, a required lesson for every cultivator.
For low-level cultivators, so-called "heaven" meant spiritual qi. Once they sensed spiritual qi and developed qi perception, they had formally entered the ranks of cultivators and set foot upon the great path of cultivation.
The higher one's cultivation, the more concrete one's understanding of "heaven" became.
The void was not empty. Spiritual qi formed its threads into a vast, stable framework, nourishing all things and all living beings. High-level cultivators needed to comprehend the laws and principles that constructed the void, making the fullest possible use of them to command heaven and earth's endless might.
At the ninth rank, a cultivator's body merged with the Dao, becoming a Grotto-Heaven of its own—equivalent to becoming a part of heaven and earth. Precisely because of this, ninth-rank cultivators were also subject to immense constraints.
Once the Yin Yang Cave Scripture reached the divine level, Gao Xian had already surpassed the ninth rank in the aspect of dual cultivation. With such a foundation, his Taiji Sword Scripture could break through, and his Taiji Idol Spirit could rise to the Saint level.
Though the Yin Yang Cave Scripture was profound, Gao Xian had never paid it much mind. After all, it was a dual cultivation art. It was useful for assisting cultivation, but utterly useless in battle.
It was not until Sister Bai reminded him that Gao Xian suddenly awakened to the fact that the Yin Yang Cave Scripture was ordinarily of no use.
At this level, one had naturally long since transcended all dual cultivation between men and women.
Gao Xian was not treating "heaven" as a woman. Rather, he was searching within the heavenly tribulation for the root of spiritual qi, using his own divine soul to resonate
