quote BlackScythe

...Zhuge Liang really rules the empire and has the Empire at Wei at his feet until his demise.

If that really is true, why did Zhuge Liang ultimately fail in ALL of his campaigns until his death, as did his student after him?

If you ask me, I believe it was vice versa, Cao Cao had both Shu and Wu at his feet until his death, and so did his sons after him, that is, until Sima Yi sucessfully betrayed them...
