The Head of the Family at the End of the Han Dynasty

At the end of the Eastern Han dynasty, as warlords vie for power, I transmigrate to that era but pledge allegiance to no faction. With the help of my golden finger System, I advance Eastern Han technology by a thousand years and spend a trillion to build the Han dynasty's first heavy mechanized brigade. After unifying the Han dynasty, I lead my army north to attack the Xiongnu, west to conquer Rome, and east across the Pacific. To reward my achievements, the emperor appoints me Shepherd of Europe.
