In final chapter of the original novel for RETURN OF THE CONDOR HEROES, Jin Yong introduced the characters of Cheung Gwun Bo (future Cheung 3 Fung), his Shaolin teacher Gok Yeun, and the concept of the 9 Yeung Jen Ging, which would serve as a foundation for the HEAVEN SWORD AND DRAGON SABRE novel he would write and publish a few years later.
As many times as ROCH has been adapted for film, television, and comic books, this scene has NEVER been included. On a practical level, I can understand that the people making the film, TV show, or comic book are just looking to end their movie, show, comic, etc., and don't necessarily need or want to bother with setting up HSDS, but still...seldom has a studio or publisher offered an adaptation of ROCH *without* following up with an HSDS project within a few years (or sooner). Might as well do the early marketing as Jin Yong did.
