When Su Wan, a graduate student in the Department of Modern History, opened her eyes, she became Xiao Chuo, the queen of Yelvxian of Liao Jingzong—the Xiao Chuo who was famous for her iron fist in history books.
At that time, the Liao Dynasty was in turmoil: the conservative Khitan aristocrats clung to the old grassland system and refused to let go, the Han ministers Han Derang and others were eager for the Chinese reform, and in the south, Taizu and Taizong of the Northern Song Dynasty were still eyeing the Sixteen Prefectures of Yanyun. However, Yelvxian was suffering from wind and illness, and the burden of the court fell half on her shoulders.
Xiao Chuo, who had the complete history of the Liao Dynasty in his memory, held the "Zi Zhi Tong Jian" in his left hand and held a bow in his right hand while riding and shooting. She predicted the flames of the Gaoliang River and dispatched Brother Yelvxiu to help in advance; she understood the route of Yongxi's Northern Expedition and forced Yang Ye and Chen Jiagu to be captured; she even fought with the Song Dynasty at the top of Chanzhou City to finalize the equal terms of the Chanyuan Alliance with her own hands.
She established a sinology hall, opened imperial examinations, and reformed taxes, walking a tightrope between conservatism and innovation; she took back Ruduo's military power, quelled the rebellion of the nobles, and used the art of balancing to hold on to power. From the grassland girl to the Empress Dowager Chengtian, she used the prophet of a time traveler to place pieces on the chessboard of the confrontation between the Liao and Song Dynasties, and finally paved the way for the Liao Dynasty to prosper with multi-ethnic symbiosis, and she became an indescribable legend in the history books.
