Before that, Xiaotian Xin had been quite confident in his sprinting technique. He had thought his retort could make Dai Li speechless.
However, after Dai Li's explanation, he knew Dai Li was right. Dai Li's understanding of sprint training was several levels higher than his.
The concluding words of Dai Li had been especially convincing. They had indicated that Xiaotian Xin's training method might cause a contraction of his hip joints, as well as a downward shift of his pelvis, which could give Xiaotian Xin some nasty surprises. These athletic injuries would slightly influence his professional life, and could even cause illness and agony throughout his life.
Before now, Xiaotian Xin had ignored this completely. However, after thinking about Dai Li's words, as well as his actual physical condition, Xiaotian Xin was fully convinced by Dai Li. He even wanted to thank Dai Li for reminding him of such an important problem.
