Li Huailin, a history lecturer from the 21st century, unexpectedly transmigrates to the Qin dynasty in 221 BC, carrying The Oxford Advanced Learner’s English-Chinese Dictionary, The Times Atlas of the World, and the Global Integration System. Just as the First Emperor completes the unification of the six states, Li uses his modern knowledge and the System’s power to enter Qin’s inner circle under the name “Li Yang.” Starting as a “spy” hunted through the streets of Xianyang, he gradually becomes a world conqueror, leading Qin’s armies across the Pamir Plateau and over the Mediterranean Sea. As English words enter the refined speech of the Qin palace and imperial roads reach the ruins of Babylon, a Qin Empire rooted in Huaxia civilization and infused with technology from across the globe begins to redraw the map of human civilization.
