The Heavenly Earth Union Scripture practiced by Cha Yuanjun, is inherently about drawing on the Yin Yang Qi and blending them marvelously.
This skill, in its operation, encompasses the strangest of capabilities, something normal people simply cannot practice.
One must possess the special trait of Yin Yang to thoroughly master it.
Even then, the transformations of the Yin Yang Qi inside the body often remain in a precarious balance initially.
It's like walking a tightrope on a cliff; a slight misstep can lead to destruction from the reverse surge of Yin Yang Qi.
Therefore, what this skill fears the most is someone forcefully infusing Inner Strength into the body, stirring the Yin Yang Qi.
It's akin to being pushed off the cliff while walking the tightrope.
However, at the stage of Cha Yuanjun, such risks are minimal.
Not to mention whether anyone could break through his defensive moves to infuse Inner Strength into his body.
