9 Yum can't cure Iron Palm injuries, but 9 Yeung can cure YM Divine Palms injuries?

[Stance]

Yup I agree that is the reason -- it is still very impressive to me though that the 9 Yang creator thought up all those theories on the fly, which Zhang Sanfeng couldn't replicate in a century of pondering martial arts.

It wasn't on the fly. He created 9 Yang after reading and modifying 9 Yin.

Obviously this process of creation is alot faster than inventing something from scratch.

Just like taking an iPhone and producing 1000 "Hiphones" vs a new mate30 etc.

Z3F didn't get the whole 9 Yang to replicate or modify, he had to invent alot of his stuff.

Now look at YG, he was able to invent something in no time lol.
