Chen Mobai saw that once the sword qi penetrated the White Stone, it quickly tainted and transformed, retaining all the characteristics of its sword qi.
With the infusion of the third Qing Shuang sword qi, he could see the sword qi embodying three layers of power, changing as fluidly as the vast emerald sky, from persistent rain to the final snowfall.
"So, that's how it works. Evolving multiple changes within a single sword Qi, incorporating all the changes. This indeed tests one's control over the sword Qi."
After watching Pei Qingshuang's demonstration, Chen Mobai understood the trick of infusing multiple kinds of sword Qis into the White Stone.
