I, Sima Yi, Must Usurp the Throne as Early as Possible

I've traveled through time! What a pity, it turned out to be Sima Yi! That cowardly old immortal! The LYB who survived three generations of the Cao family and finally stole the world by farting in Luoshui. It is also the source of all evil that leads to the chaos in China and the migration of people to the south! No, absolutely not. Now that I have become him, I have to change everything. How can it be done after such a long time! What's the point of usurping power at the age of seventy? It's already here, it's not early yet.
