I don't think they will add something relate to YG's children at the end, because if they do that then the whole mystery about the girl in yellow dress in HSDS will be ruined. Instead i hope they will add the last chapter of the novel where YG, XLN and Guo Xiang go to Shaolin and meet Zhang Sanfeng (who created the Wudang sect) for the first time and explains how Jiu Yang Zhen Jing hidden in the monkey's stomach.
