Liu Dashui, a young man from the modern countryside, accidentally traveled to a time of great disaster in ancient times. The fields were starved to death, plague was rampant, the government failed to act, and powerful men took advantage of the situation to plunder. With no experience in ancient times, he relied on modern knowledge and tenacity to teach people how to make simple water purification devices, then improved agricultural tools and promoted hybrid crop cultivation. In the confrontation with natural and man-made disasters, he not only had to solve the food crisis, but also faced the calculations of local evil forces and the suspicion of court officials. See how an ordinary time traveler can turn the tide in a desperate situation, write his own legend, and become the "savior" in the hearts of the people.
