Chen Mo assumed the role of a postman in the Xi'an Prefecture in the early years of Chongzhen. It happened that the court was abolishing the post, and his job was about to be lost. He still owed usury to the landlords. At the critical moment, the "People's Livelihood and World Aid System" is bound. Complete the task of "Improving the food of the post soldiers" to get coarse grains, and "repair the post stables" to get farm tools! While others were dawdling, Chen Mo used the system to work in farming and practice rural bravery, from rescuing hungry people to quelling banditry, and gradually escaped from the bottom. Chongzhen is short of food? He sent high-yielding crops; the frontier army was short of pay? He opened trade routes to generate income. From a postman to a county magistrate, and then to a feudal official, Chen Mo used his mortal body to help the world, protect the people of the Ming Dynasty, and became a powerful official in the chaotic times of the late Ming Dynasty!
