Zhou Ye, a delivery boy in the old city, specializes in taking orders that no one dares to touch: items that are restricted, sealed, and missing. He lived like a leftover in the city, walking through the zoning lines with his head down every day, until the "error ledger" recorded every late arrival, route change, and lost item as an abnormal coordinate.
When others regarded the anomaly as an accident, he regarded the anomaly as a clue; when the officials were busy sealing off the district, he had already followed a list of lost items and found out the truth about the city being cut into pieces. A delivery, an evasion reminder, and a piece of truth. Zhou Ye began to use the lowest-level delivery route to pursue the top-level shady story.
But the more I looked up, the more it seemed like someone deliberately fed the entire city to anomalies. Who wrote the ledger? What is sealed behind the partition? And will the next order be delivered in his own name?
