Shen Guiyan lurked in Beiliang for ten years and returned to the Zhou Dynasty with arrow wounds and full of secrets. He thought he would be greeted with merit and glory, but instead he was thrown into a "ghost-seeing" inspection room where only he and a lame cat were.
The border is in crisis and refugees are everywhere, but the DPRK and China are enjoying peace and harmony. He soon discovered that the real enemy was not in the enemy's country, but around him - the gentle and elegant Li Heting from Zhongshushe, who turned out to be a three-faced spy who had been infiltrated for many years. Xiao Zhao, the eldest princess of Beiliang, is his mortal enemy and the only person who can understand his words.
From false intelligence to forged secret edicts, from the teahouse in the south of the city to the black market at the border, Shen Guiyan used the stupidest method to investigate the deepest case. He has no backer, no helpers, only a dying accountant, a few refugees who want to live, and a heart that has not yet cooled down.
When the truth surfaced, he faced a choice more difficult than life and death: stay in the court and get promoted and make a fortune, or go to the border to guard the uncared-for people?
This is a one-man war. He couldn't afford to lose, because behind him there were people who farmed, people who built city walls, and people who died on the battlefield and had no one to collect their bodies.
Purpose: Give a voice to the voiceless.
