Zhou Ming was an ordinary courier until he discovered that he could see the "sin points" on other people's heads. That day, he received an order to be delivered to the old city. The recipient was an old man living alone in a Tongzi building. The package is not big and is cold in hand. When the old man signed for it, Zhou Ming saw the number above his head jump from "17" to "Annihilation". News broadcast that night: The veteran killer "Razor" died of natural causes at home. The phone rang, a new order popped up, and a line of small words was written in the remarks column: "Deliveryman Zhou Ming, welcome to join 'Order Express'." From that day on, the packages he delivered began to change the world - or end some people who should not exist.
