Hanyueguan

In 2217 AD, Chen Yue, a doctoral student in the Department of History, was accidentally electrocuted to death while looking up Han bamboo slips in the library. When he woke up, he found himself outside the city of Didao in Longxi County in the second year of Yuanshou, Emperor Wu of the Han Dynasty (121 BC), possessing the body of a garrison soldier who had just been shot by a Xiongnu ranger.
