In a previous life, Cheng Yan, a border postman, was ordered to deliver a military report. Heishiguan subsequently withdrew its troops, Linchuan Post was burned, and he became a collaborator and died at Yanzhou execution ground.
When he opened his eyes again, he returned to the snowy night where he received the letter.
The letter must be delivered, and the deadlock has begun. Cheng Yan didn't know who was behind the scenes. He only remembered a few flaws that no one believed: a batch of military rations that should not have left the customs, a military order with complete procedures, and the inn that burned down five days later.
He is just a postman at the lowest level. He has no soldiers, no power, and no system to predict everything. This time, he could only write down everything he saw with his own eyes in the book, leaving gaps for inspection in every procedure used to kill him.
When the door is closed again, Cheng Yan must find the real enemy between military orders, food roads and people's hearts, and find a way for himself to survive.
