Report to Chang An

A history college student who picked up Taibai's handwriting unexpectedly fell into the wind and sand of the Western Regions in the late Tang Dynasty; a Sogdian girl carrying an agate cup carried the Tang flag of Guo An's Western Army; border residents with their families and a painter depicting Feitian walked through the twenty-six cities of Qiuci, Loulan and Shazhou, looking at Chang'an. From the twenty years of isolation in Anxi to the uprising of the Guiyi Army, from the desperation of the snowy mountains to the wind and snow of Wushaoling, they sewed the Feitian murals and the nostalgia of the people on the way home thousands of miles away. When the treasure protector's white clothes are stained with blood, only the crazy man is left to guard the tomb in Chang'an. The jade cup finally enters the court, can the loyal and brave return?
