Lin Yuan accidentally "saved" a young postman in the late Ming Dynasty with a meal of braised pork, and was involved in the troubled times of the late Ming Dynasty. The main line is how the protagonist uses modern materials (such as medicines, potatoes and sweet potato seeds), information (historical knowledge) and limited time and space rules to start from a small post, step by step to create a "peach blossom garden" in troubled times, and ultimately affect the general trend of the world.
Very good, very innovative and unconventional
