The plot generally follows the novels but some new changes have been introduced, creating links between the original story and the Condor Trilogy, another set of novels by Louis Cha. Tian Guinong is given a greater role as the primary villain - he survives the fall after being knocked off a cliff by Hu Fei and returns as an even more powerful foe.[citation needed] Apparently, Tian discovered Li Zicheng's treasure in a cave at the cliff's base and found a martial arts manual detailing Zhou Botong's famous skill, the 'Technique of Ambidexterity', along with the reforged Heaven Sword and Dragon Saber.[citation needed] He masters the skill and uses his new weapons to face the protagonists once more. Characters from The Book and the Sword are also given greater roles in the series.[citation needed] The cliffhanger ending in the novel is also replaced by a happy reunion for Hu Fei and his third love interest Miao Ruolan.[citation needed]
