The Abbot's Growth Story

I heard that the Nine Yin Manual and the Nine Yang Divine Art are very powerful. Is there anything more powerful than this? So much! The Nine Yin Manual and the Nine Yang Divine Art are just fragments of a real martial arts myth. Even if you know both, you have only scratched the surface. Moreover, these two martial arts are actually closely related. Many people who secretly practice these two martial arts are at least ignorant of the key points, and at worst, they are obsessed with it, because they do not know the method. Once they master the correct way to open it, they will be like a fish in water and get twice the result with half the effort~
