I accidentally traveled through the late Han Dynasty, but I have the entire history of the Three Kingdoms in my mind - this is not luck, but a heavy opportunity.
From merging troops with states, to dividing the world into four quarters, and then to unifying the country. Cao Cao, Yuan Shao, Liu Bei, and Sun Quan are each true heroic opponents. There is no system, there is no golden finger, there are only three things you can rely on:
A prophet of history, my own brain, and a group of brothers to whom I can trust my life.
The country is like a chess game, with murderous intent at every step. In this life, history will be rewritten by me.
