Although Situ Qing was the top among all evolvers and was about to become a surpasser, it did not necessarily mean that he was better at black and white boxing.
Black and white boxing did not have much to do with strength or speed. What was important was the control of one's body, judgement and state of mind.
Because Han Sen had practiced Jadeskin, the control he had over his own body and strength was not worse than an evolver, and the other two factors had nothing to do with status.
Han Sen had just started to practice Yin Yang Blast, and he was very much inspired by its theoretical knowledge.
Bai Yishan was right in that it was not dangerous to practice and also helpful to increase his fitness.
The danger of Yin Yang Blast was in its usage.
Using the yin force and yang force at the right moment was extremely challenging for the users. If a mistake was made, the users themselves would be hurt instead.
