As soon as the seventeen-year-old new emperor Xiao Che ascended to Dabao, the Beidi cavalry broke through Yanmen Pass, and the war was directed at Chang'an. Above the court, Wei Yong, the wily and scheming Taifu, holds power and is eyeing the power; Zhao Chengyu, the fierce and brave hussar general, has his own troops and shows his sharpness; Shen Congyuan, the Zhenbei general who is far away in the northern Xinjiang, seems to be loyal, but he has hidden secrets.
An emergency report at the border opened up the undercurrent under the guise of a prosperous age. Xiao Che knew very well that under the dragon chair, there were all the lights and shadows of swords. As the young emperor, he made a dangerous move in the Zichen Palace: he mobilized the Lingnan Army to rush thousands of miles to help, and sent the Yulin Guards to escort the grain and grass. It seemed to balance all parties, but in fact he was making every step of the way.
In the sound of Beidi's iron hoofs, there is the blood of loyal ministers, the calculations of treacherous people, and the invisible threads entwining the imperial power and people's hearts. Xiao Che must learn to check and balance in the flames of war and intrigues, discern authenticity between betrayal and loyalty, and hold on to the thousands of miles of land in the swaying wind and snow.
The snow in Chang'an will eventually stop, but once the chess game of power begins, there is no way out. Can he carry the world on his young shoulders and have the last laugh in this life-and-death game?
