In the twenty-third year of the Yuan Dynasty, two otherworldly souls crashed into the territory of the Yuan Dynasty. In the golden bloodline of the Borzhijin clan, a military fanatic from modern times awakened, bound to the "longitude and latitude system", and wanted to restore the family's glory in the game between the grassland and the court; but the lustful boy of the Boya Wutai clan put on the Quanzhen Taoist robe and carried the "Xuanzhen system", hoping to use alchemy and Taoist talismans to survive for the aliens in the disputes between Buddhism and Taoism. One is working step by step in the whirlpool of military and political affairs, and the other is exploring the obstacles in the world outside. When the Mongolian scimitar meets the Taoist Qingfeng, the two reborn people with the system will eventually set off a storm that rewrites history in this era of iron cavalry.
