On a rainy night, deliveryman Lu Xiaofeng crashed into a tree while delivering orders. When he opened his eyes, he became a postman at Yanmen Pass in Dajing. All that was left in his arms was a deformed takeout box - a lighter and an order record book inside, which became his life-saving trump card.
Dysentery was raging in the post camp, so he borrowed cotton linings from take-out boxes to learn how to keep warm, boiled water to prevent the epidemic, and risked his life to protect half of the people in the camp; the mail delivery route was far away, so he copied the take-out zoning scheduling logic, saving a lot of horses; when the northern barbarians attacked, the grain truck froze, so he modified the grain truck to deliver warm grain. He was appreciated by the border general Niu Yanhao, and was promoted from post soldier to grain officer.
After entering the capital to take charge of logistics, he and his ally Li Mo, from a poor family, promoted the official assessment system and assisted Zhang Jingzhi, the leader of the war, and used secret reports from the inn to uncover the crime of treason between the two princes. Emperor Jing was seriously ill, so he used "takeaway style" precise arrangements to stabilize the food supply and quell the civil strife among the gentry. Finally, with the petition of all the people, he ascended the throne and changed the Yuan Dynasty to Xinjing.
After ascending to the throne, he promoted equalization of land, reformed commercial taxes, built practical colleges, and doubled grain production with new plows and waterwheels. The Northern Barbarians and Western Regions came to pay tribute. In his later years, caressing the old takeout box, he still remembered his original intention of traveling through time: to let the people have food to eat and fields to farm. Until he died of illness, his last wish was to be buried next to the old inn and rest in a box. The survival wisdom of a deliveryman finally watered the flowers of prosperity in ancient times.
