Pei Zhao was just a low-ranking soldier in the army, tasked with leading horses and delivering supplies.
One afternoon, a blood-soaked stranger stopped his horse and asked just one question: "How many times has the wooden clapper sounded?"
Then the man slipped a short flute and a fragment of a score into the supply sack before being shot dead in the street.
To save his own life, Pei Zhao lost two military horses. After the third clapper, his identification token was voided, and the army began hunting for him.
Even stranger, the people in the camp already knew about the folded score, though it had never been shown to anyone.
The side warehouse at Xingjiao Gate, a handover scheduled for the following morning, a name that had been erased...
Pei Zhao thought he had found a plea for help.
Only later did he realize it was a thread.
At the other end of that thread lay the darkest secret in the entire city.
