I Am Cao Cao of the Three Kingdoms

I traveled through time and became Cao Cao. I thought I could use the emperor to control the princes and unify the world. But who appears again, but this time traveler actually has a system. I thought that when this time traveler took action, he would actually become a reincarnation person. I couldn't bear it, but he actually told me that this world is a world of immortals and heroes, and there are also the Great Qin, the Great Han, the Great Jin, the Great Sui, the Great Tang, the Great Song, the Great Yuan, the Great Ming, the Great Qing, and other nomadic tribes such as the Great Jin, the Liao Kingdom, the Khitan, and the Xiongnu. I couldn't bear it. Do you have the guts to give me another Japanese concave-convex man? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
