"Lin Tian, although I can't understand your techniques, I have noticed a pattern. Why do you always apply each technique exactly nine times?" Zhang Lingyu asked, unable to hide her puzzlement, although she could grasp a little.
Lin Tian's hands continued to move as he naturally replied, "I don't fully understand the specific reason myself. The Nine Needle Technique contains many records about the number nine; the 'nine' in the name of the technique implies that techniques are to be applied in groups of nine, with nine groups making a complete cycle, using ninety percent of strength, piercing to a depth of nine-tenths, and there are also nine types of needle shapes, and so on—everything is based on the number nine."
"Why is that?" Xiao Manxuan also asked, her curiosity getting the better of her.
Zuo Xing'er didn't ask, but her gaze was fixed intently on Lin Tian as if awaiting his explanation.
