- **Era Background**: After Xiangyang City was destroyed in the late Southern Song Dynasty, the people of Jianghu established anti-Yuan strongholds in the mountains of Bashu. The story took place ten years before Zhang Wuji led the Mingjiao uprising, and there was an undercurrent of martial arts in the Central Plains.
- **Geographic Layout**: Taking the secret realm of the Ancient Tomb Sect as the starting point, it is connected to the Yanziwu ruins of the Murong Family to the east, to the west is the poisonous miasma forest of Tangmen in Central Sichuan, and to the south is the isolated island of the Sword Sect in the South China Sea, forming a rivers and lakes pattern with intertwined forces.
- **Martial Arts System**: Retains the essence of Jin Yong's martial arts, focusing on the Qing Gong of the Tomb Sect and the secrets of the "Nine Yin Manual", the Murong Family's changeable tactics centered on "The Stars Shift", and the Tang Sect's weird moves that combine poisonous techniques with mechanisms.
