Wang Ba's expression didn't change, but he had already understood in his heart.
"Using the rules of Yin and Yang to trigger my instincts, and then attack my Dao-heart... Interestingly, rules can be used in such a way."
Humans are driven by their desires, and though a Cultivator's Dao-heart is firm, it is not easily swayed by such instincts.
But these are the inherent instincts of living beings, difficult to completely erase.
Once they counterattack, it's like a flood or a wild beast, easily provoking a backlash against the Dao-heart.
A backlash against the Dao-heart can cause instability at minor, and at worst, lead to Heart Demons, threatening one's life.
However, Wang Ba was not unfamiliar with the rules of Yin and Yang, and the opponent's application of these rules was hardly sophisticated in his eyes, so he snorted coldly.
