司馬懿
During the stalemate, when Zhuge Liang sent a messenger to meet Sima Yi, Sima Yi asked the messenger about Zhuge Liang's daily routine and living conditions. The messenger said that Zhuge Liang consumed three to four "sheng" of grain a day and that he micromanaged almost everything, except trivial issues like punishments for minor offences. After hearing this, Sima Yi remarked, "How can Zhuge Kongming expect to last long? He's going to die soon."
