who proceed to attack Song and Dali thereafter. Guo uses the tactics from the Book of Wumu, his understanding of Mongol warfare, Xiangyang's natural barriers (the Han River waterways and the surrounding mountains), and his allies from the wulin (martial artists' community) to counter the invaders for 46 years. However, after the loss of a nearby fortified city Fancheng, Guo Jing eventually dies a martyr when Xiangyang finally falls to the Mongols. Before Guo's death, he hid the Book of Wumu in the blade of the Dragon Slaying Saber. The latest edition of The Heaven Sword and Dragon Saber states that the manual was hidden on Peach Blossom Island, together with the Nine Yin Manual and the 'Eighteen Subduing Dragon Palms' manual. The Saber carries a piece of an iron-plated map of the books' location, while another half of the map is in the saber's counterpart, the Heaven Reliant Sword. The Saber is passed on to Guo Jing's son Guo Polu, but is later lost in the wulin by the time of the Yuan dynasty. The Sword comes into the possession of Guo's younger daughter Guo Xiang, who founds the Emei School later. The Heaven Sword and Dragon Saber Nearly a century after the Battle of Xiangyang, the Dragon Slaying Saber is taken by Xie Xun after it is found by the Heavenly Eagle Cult. Xie keeps it with him for several years as he lives on an isolated island away from the Chinese mainland. He loses it to Zhou Zhiruo later. Zhou breaks the weapon by clashing it against the Heaven Reliant Sword, and the items hidden in the blades are revealed.

He passes the book to Xu Da later and Xu becomes a brilliant military leader after studying it.
