The original title of the book is: I, a Poverty Alleviation Cadre, Helped the First Emperor to Unify the World. There are too many words to name. This is a different Da Qin. Because I prefer Da Qin, I use Da Qin as the background to express some of my thoughts. Whether now or in ancient times, I hope that such a person will appear to change the status quo. Zhang Yuan, deputy director of the County Poverty Alleviation Office, encountered a flash flood while escorting poverty alleviation materials to the countryside. When he woke up, he found that he had arrived in the Qin Dynasty. Due to the vast land, sparse population and different dialects in ancient times, he mistakenly believed that this was a mysterious "deep poverty village" in the country. He was determined to use modern poverty alleviation experience to lead the "extremely poor households" to make a fortune, and ultimately unknowingly promoted the technological leap and global expansion of the entire Qin State.
