Xu Fei, a 35-year-old social animal teacher, accidentally transformed into Zhu Youlang, the Yongli Emperor of the Southern Ming Dynasty who fled to Yunnan in a hurry. Faced with the endless internal strife in the court, the pressing Qing army, and the "countdown to death" with only one year left, Xu Fei, who was familiar with history, did not despair. He decided to use knowledge and patterns that transcended the times to carry out a complete "transformation" of this empire that was hard to recover from. Starting from establishing a foothold in Yunnan, we have purified internal affairs, reformed the military system, developed science and technology, and united vertical and horizontal forces to reverse the destiny step by step. But he knew that driving away foreign enemies was only the first step. How to break the three-hundred-year dynasty cycle was the real challenge. This is a race against time for self-rescue, and it is also a great experiment to reshape Chinese civilization.
