They were not mentioned at all in Smiling Proud Wanderer. Did this formely illustrious clan appear in other periods?
It is said that Qiu QianRen and his teacher Shangguan improved the Iron Sand Palm technique, making it a Great level martial art.
Some say that Qiu QianRen was a step below the Greats. But since Qiu QianRen lived longer than Hong Qigong and Ouyang Feng, and since the post 16 years Yi Deng was said to be only barely better than Qiu, I think Qiu QianRen would be better than Hong and Ouyang at their deaths, therefore giving him the level of a Great.
Qiu did not benefit from 9 Yin in any way either, his power derived entirely from the Iron Sand Palm clan's martial arts.
Now, although the Iron Sand Palm is a Great level martial art, did Qiu teach any successor this skill, or was it lost to the sands of time? Did he teach anyone the improved variations imparted to him by his teacher Shangguan? Were Qiu's own variations lost as well?
Qiu seemed like a cheapstake when it came to sharing martial arts. He did not even teach his own TWIN BROTHER any good martial art. How good was the other Qiu twin anyway? Could he beat 2 of the Freaks by himself?
Since he did not teach even his brother, it's possible that the improved Iron Sand Palm was lost. Or maybe Qiu recorded it? I think he must have. He obviously still practiced martial arts during all these years. It would have been basic courtesy to return to the clan what he received, and leave a manual to a successor.
Do you guys think the Iron Sand Palm could have played a key role in the power struggles of later periods if they have a complete Iron Sand Palm manual in their hands?
