Lin Mo, a geek in science and engineering, accidentally traveled to the late Qin Dynasty, made a living with improved farm tools, and borrowed new buckets to work as a craftsman in the palace. With his knowledge of modern science and technology, he built curvy plows, waterwheels, simple cement and other rare objects in the Qin Dynasty, and he was able to work among influential figures such as Qin Shihuang, Zhao Gao and Liu Bang. In troubled times, he not only had to rely on inventions to survive, but also faced choices that changed history, writing a different kind of legend in the Qin and Han Dynasties (any similarities are purely coincidental)
