Paper Kills Xuanwumen

Every stroke is murderous. One case and one volume can determine the destiny of the country. In Chang'an, which has been in the seventh year of Wude, under the prosperous age, murderous intentions are undercurrent. Du Heng, a ninth-grade scribe, just wants to be an inconspicuous and transparent person in the imperial bureaucracy and survive in troubled times. Until his colleague Chen Yizhi died suddenly and tragically in a dark alley. A cross mark hastily engraved on the document dragged Du Heng into the endless abyss. Only then did he discover that Chen Yizhi's death was not an accident, but because they had glimpsed a secret together that could subvert the empire - there was a pair of invisible black hands named "Tingyu Si" who were using a mysterious technique called "mirror imaging" to forge seals on documents and ink, tamper with military orders, and quietly mobilize armor and sharp arrows that could arm an army. From then on, Du Heng's world was divided into two. On the surface, he is a humble, cowardly green-robed official in Shangshu Province who can only bury his head in documents. Secretly, he must walk on thin ice under the supervision of the East Palace, King Qin, and even the mysterious chamberlain. From the subtle anomalies in the documents, to the secret flow of water transportation, from the secret transactions of Hu merchants, to the huge flow of money in underground banks... With his unparalleled sensitivity to document rules, he searched for clues about "Tingyu Si" between the lines. He gradually realized that all the clues pointed to a shocking conspiracy, and its end point was the core of the empire's power - Xuanwu Gate. Now, he holds key evidence and knows when the storm is coming. On one side is the "Tingyu Si" who is pressing forward step by step and killing people invisible; On one side is the morning bell that is about to ring and determine the fate of the Tang Dynasty. Xuanwu Gate.
