"The Legend of Guo Huang" takes over the previous story of "The Legend of Heaven and Sword of the Dragon", focusing on the ups and downs of the world and the tragedy of family and country before and after the destruction of Xiangyang City. Guo Jing and Huang Rong led a group of heroes to defend Xiangyang, but they were attacked by beggar gang traitors and the Mongolian army from both inside and outside. When the city was broken, Guo Fu died in battle and Guo Jing died in battle. Huang Rong, carrying copies of the "Nine Yin Scriptures" and "Wu Mu's Suicide Notes", breaks out with Yeluqi and Cheng Ying's disciple Huang Shan'er and rushes to Peach Blossom Island, determined to fulfill Guo Jing's last wish - to forge the Yitian Sword and the Dragon Slaying Knife, and hide the secrets deep inside, waiting for the rise of heroes in the future.
On the way, the Mongolian troops pressed hard, the former beggar brothers turned against each other, and Peach Blossom Island was also coveted by the undercurrent. Huang Rong leads everyone with wisdom and tenacity, guarding the fire of the Han people's restoration amidst the light and shadow of swords. Yeluqi uses Quanzhen swordsmanship to support the crisis, and Huang Shan'er grows rapidly in the blood and fire.
This is not only a record of martial arts inheritance, but also a magnificent song of feelings about family and country. In the setting sun of Xiangyang and the sound of waves on Peach Blossom Island, it describes the tragedy of the hero's end and the hope of passing on the fire. It fills in the unsaid origin of the sword and the secrets of the world.
