The Western Region of the Tang Dynasty, the border town of Xizhou. Hu merchants and Han people lived together in the same city, and camel bells and Qiang flutes intertwined into the night.
Pei Jin, a member of the judicial army, was demoted from Chang'an. The first case he took on was the bloody business road with twenty-seven corpses outside Liuzhong City. The deputy general of the border guard has concluded that there is a "vendetta between Hu and Han", and Ashinayan, the leader of the Huihe women, is about to be executed.
But the Uighur scimitar left at the scene was sewn with Sogdian stitches; the fire started from the inside of the burned cargo box; and a standard arrowhead of the border guard was buried under the red willow bushes in the Gobi.
The laws of the Tang Dynasty must be enforced, tribal customs must be respected, the frontier generals must be given face, and the balance of the governor must be maintained. In the midst of the tug of war, this green-robed civil servant stepped into the intricate dark network of Xizhou City with a volume of "Tang Laws and Commentary", an arrowhead, and the trust of a Huihe woman.
From business murders to arms smuggling, from tribal feuds to court chess games. In this lonely border town in the Western Region, someone wants to use swords to divide people into you and me, but he just wants to use the law to guard the word "justice".
