Do you have that ability?

"Do you have that ability? You're just a half-Saint, and you want to kill me?" Shi chenhua's wrist turned nimbly, and a stream of flowing light flew out from his middle finger. It curled around like an invisible soft whip, forcing Zi Yin to take two steps back. Then, he moved past her and grabbed her pulse. Zi Yin's body went soft and she couldn't move.

Ling Chuxi's eyes narrowed. What Shi chenhua had used was obviously not a martial arts technique, but its power was definitely not inferior to any martial arts technique.

This must be the wondrous technique that Huangfu qingjue had mentioned. She had heard from Zi Yin before that in the heaven domain, cultivators started off with martial arts, stimulating their body's potential to cultivate their true Qi and Yuan Qi. However, after reaching the Grandmaster level, one could comprehend the laws of heaven and earth, use their Yuan Qi to cast spells, or refine their domain.
