**Introduction to the work**
Jiang Wandeng, the only female watchman in Bianjing City, inherited the bangle chime from her late father, and spent the long night asking for peace in the world.
An accident on a rainy night gave her a glimpse of the forbidden transaction between the prime minister of the dynasty and the secret envoy of the Liao Kingdom. From then on, her voice was no longer pure, and every step she took was on the tip of a knife. Above the court, the main war faction and the main peace faction regard her as a pawn; in the arena, various forces covet the most detailed picture of Bianjing's night journey in her mind.
As a watchman, she weaved an intelligence network all over ghost markets, water transport, and high-end back alleys; using the rhythm of banging as a signal, she conveyed life and death messages between the Imperial City and the Prime Minister's Office.
The stern man who was rescued by her on a rainy night and disguised as a down-and-out poet was actually the commander of the Imperial City who held the power of life and death. From testing each other to back-to-back trust, the two work together to protect the city that is about to be swallowed by the night.
In the long night, surrounded by traitors, what she wants to sound is not only a watch to tell the time, but also a warning bell for the Song Dynasty!
