Heroes have great ambitions in their chests, good strategies in their bellies, and the opportunity to hide the universe. Those who have aspirations of heaven and earth say so.

Cao Cao said: "A hero has ambition, a good plan in his belly, an opportunity to hide the universe, and an ambition to breathe heaven and earth."

Liu Bei said, "Who can it be?"

Cao Cao pointed to Liu Bei with his finger, then pointed to himself and said, "Only the monarch and Cao Er are heroes in the world today!"
