Datang: Guard Chang'an City for 99 Days at the Beginning

Li Huan traveled to Chang'an City during the Anshi Rebellion, and Emperor Xuanzong of the Tang Dynasty had just escaped with Concubine Yang. Li Huan originally planned to run away, but unexpectedly he awakened the mission system. Every time he successfully defended Chang'an City for five days, he would have generous exclusive rewards waiting for him. So, Li Huan gritted his teeth and imitated Cao Cao's thieves, went to Maweiyi, kidnapped Li Longji, rescued Yang Guifei, and held the emperor hostage to order the princes. Never let the prosperous Tang Dynasty fall from now on. We will never let the Anxi army fill the city with white-haired soldiers and hold Tang swords until death. He kicked the Tibetan and Uighur Turks, and punched the foodies to fight for hegemony in Central Asia. Li Bai: Li Huan's two-sleeved Green Snake Sword to Open Heaven's Gate is far superior to my Green Lotus Sword Technique. Tang Sect: Li Huan's mechanism skills are far superior to our Tang Sect's hidden weapons. An Lushan: My life is at an end! This novel and its characters are purely fictitious.
