Yes, there is a Wudang Sect in the novel, so it was not a concoction of the imaginative minds at TVB (although in general, the adaptation with Tony Leung was as far away from the novel as it could get).Originally Posted by Xi Men Chui Xue
Most readers agree that it takes place some time in the Ming Dynasty (after Smiling Proud Wanderer, some say), because Wudang was already established. However, in order to determine whether it comes before or after Smiling Proud Wanderer, one would have to look at the leaders of Shaolin and/or Wudang during that era. If the order of leadership could be ascertained, the position of Xia Ke Xing on the JY timeline can then be confirmed.
