This novel is adapted from ancient historical stories. At the end of the Liao Dynasty, the Jin soldiers pressed the territory, and Emperor Tianzuo fled in ignorance. Yelu Dashi, a distant branch of the royal family - the only Khitan scholar in the Liao Dynasty for two hundred years - led 200 cavalry to break through the encirclement westward when his country was ruined and his family was in ruins. After crossing the desert, climbing over the snow-capped mountains, and experiencing plague and pursuit, he regrouped in the city of Kedun, but suffered a disastrous defeat during the Eastern Expedition to his homeland. Faced with the "East that he could not return to," he resolutely turned to the west, defeated the greater number with less in the Katwan grassland of Central Asia, defeated the 100,000-strong Seljuq coalition, and established a huge empire across Central Asia - Western Liao.
However, when the empire was first established, the hero became old. Yelu Dashi died of illness at the peak of his power, leaving behind the young queen Xiaota Buyan and the young prince. This woman who came from the grasslands has supported the empire for twenty years with her iron fist and wisdom. Her daughter Yelvpu Suwan was so ambitious that she killed her husband to seize power, bloodbathed the court, and was eventually imprisoned until her death. The rise of the Mongolian cavalry caused the dynasty established by the exiles to collapse eighty-six years later.
This is a story about "not giving up". One person, two hundred cavalry, 30,000 miles, Guozuo in the 86th year. When the motherland ceased to exist, he spent his life proving that the soul of a nation is not its territory, but its faith.
