Li Ming, a graduate student in the Department of History, accidentally traveled to the Xianyang Palace of the Qin State in 228 BC. He was responsible for the mysterious "Universal Unification System" and became the guest of Qin Shi Huang Ying Zheng. His mission is no longer just to study history, but to personally participate in and change history - not only to help Qin complete the great cause of unifying the six countries, but also to help Qin's cavalry and civilization move out of East Asia and move towards true unification of the world.
