The Dali Dynasty has exhausted its vitality. There are demon clans outside and treacherous ministers disrupting the government. The deposed prince Li Hanyi was exiled to the north to guard the mausoleum for ten years because of his "naturally useless body". Everyone thought that he had froze to death in the snow, but they didn't know that he spent ten years guarding the tomb not to cultivate spiritual energy, but to cultivate "national destiny". He uses his own spine as the bone of his sword and the thousands of miles of mountains and rivers as his sword intention. At the end of the ten years, the demon emperor's troops came to the city, and Dali was about to die. Li Hanyi held a rusty iron sword and pushed open the gate of the cemetery. With one man and one sword, he fought back to the imperial capital from the north and reorganized the country.
