The mountains were blocked by heavy snow, and military reports were subcontracted. Qingshi Fort, forty-two miles away, knew nothing about the enemy's attack.
Jiang Yan, who was an emergency logistics planner in his previous life, when he opened his eyes again, he had become the lowest postman at the border, with the body of the messenger on his body.
What he woke up with was a torn scroll of "Mountain and River Station Map".
It cannot produce food or summon soldiers and horses. It can only record roads and calculate journeys. But at this time, in Qingshi Post, the post horses were sold and the food was only enough for three days. The post chief was busy burning the accounts and escaping for his life. There were still 20 disaster victims outside the door who had nowhere to go.
Jiang Yan could only start from a bowl of porridge, a sick horse and a post road that was about to be blocked by heavy snow. He recruited refugees, built a horse team, set up post regulations, opened trade routes, and turned a dilapidated post station that everyone wanted to give up into a lifeline connecting the border town with the world.
Many years later, the princes are still fighting for the city, and the powerful officials are still blocking the news.
But they finally discovered——
What really determines whether a city can survive is never how high the city walls are, but whether a letter, a bag of food, and a supporting army can arrive in time.
