During the Tianbao period, the territory of the Tang Dynasty expanded thousands of miles westward, and unexpectedly discovered an unknown continent. This land was in the turbulent times at the end of the Yuan Dynasty, and uprisings broke out all over the Central Plains. Two dynasties that were supposed to be separated by six hundred years met here. The Tang Dynasty wanted to expand its territory, but the heroes in the late Yuan Dynasty regarded the sudden appearance of the Eastern Empire as a huge threat. The two civilizations came into contact under a new geographical pattern, and trade and conflict sprouted at the same time. Both sides found that the other side had completely different military systems, political systems, and governance philosophies. In this new land, the fates of the two dynasties began to intertwine, and a collision of civilizations and a game of power across time and space quietly began.
