Genius in the Late Han Dynasty

I was reborn as a little Orion with the same name in the late Han Dynasty, and I traveled around the Three Kingdoms with the help of a space jade pendant that transcended the three-dimensional world. Under the setting sun of the Han Empire, fight against the Xiongnu, conquer the barbarians, and quell the civil strife. He and the fierce generals and advisers were on the side of each other, calling each other brothers and sisters, and separatist power. Can these three countries still stand on "three pillars"? This time, you have to listen to me.
