The Lone Loyalist of Anxi

In the winter of 789, the Tang Dynasty was weakened in the wake of the An Lushan Rebellion. The Anxi Protectorate had lost contact with Chang'an, 100,000 Tibetan cavalry were at the borders, Shule had fallen, and Qiuci was on the brink of disaster. White-haired Protector-General Guo Xin led more than 10,000 surviving Anxi troops in a desperate defense of the Tang Dynasty's last spark in the Western Regions.
