Logically speaking, the March God-Killing Palm was only an F-rank martial technique. In the original move recorded in the martial technique database, it might seem beautiful and powerful in the eyes of ordinary people, but in the eyes of martial artists, it was overly complicated and weak.
After Chu Nan's refinement and improvement, the moves of the March God-Killing Palm were clearly much more reasonable. Coupled with the Internal Breath circulation cultivation method given by Chu Nan, from the perspective of ordinary martial artists, the power was much stronger than before.
However, after Chu Nan actually practiced it, the power of the first ten palms indeed increased after his modification. However, at the eleventh palm, he was surprised to discover that this palm strike felt clearly different from the first ten palms.
