During the Shenlong and Jinglong years of Tang Zhongzong (705-709 AD). This was the period of fierce struggle between Queen Wei, Princess Anle, Wu Sansi and other forces and the royal family of Li and Tang Dynasties after the "Shenlong Coup".
The core of the struggle: the competition around the "Gaozu Sword Jue" (symbolizing the orthodoxy of Li and Tang Dynasties) and the "Zetian Relics" (recording the secrets and martial arts of Wu Zhou).
Prince Li Chongjun was dissatisfied with the dictatorial power of Empress Wei and Wu Sansi, so he secretly ordered Li Mubai to retrieve the "Gaozu Sword Art" that symbolized the orthodoxy of Li Tang to boost his prestige. This search triggered the involvement of good and evil, and the involvement of various forces from the government and the opposition, and finally triggered the "Jinglong Palace Incident" in the first year of Jinglong (707 AD) - the prince led his army to kill Wu Sansi, but was ultimately defeated and died. Li Mubai experienced the collapse and reconstruction of his faith during this great change.
