After falling off a cliff, modern poverty alleviation official Zhao Long accidentally finds himself in the Great Qin dynasty. Mistaking Qin Shi Huang, Ying Zheng, for the impoverished village chief known as Old Zhao, he devotes himself to helping Zhao Village escape poverty. However, Ying Zheng sees Zhao Long as an extraordinary man sent from heaven. Through Zhao Long's casual remarks and everyday knowledge, he hears about grain production, people's livelihoods, the Xiongnu, Xu Fu's deception, and the future crises facing Great Qin. The more seriously Zhao Long takes his poverty alleviation mission, the more restless Ying Zheng becomes. What began as a misunderstanding unexpectedly becomes the starting point for rewriting the fate of Great Qin.
