What does it mean that the only heroes in the world are Shi Jun and Cao Er?

What Cao Cao said to Liu Bei while they were drinking and discussing heroes. That is to say, in Cao Cao's eyes, the only people who could become heroes in the world at that time were Cao Cao himself and Liu Bei, and the others were not as capable as them. It was also Cao Cao's admiration for Liu Bei that finally caused Liu Bei to rush away from Cao Cao, fearing that he would be killed by jealousy.

Simple, Cao Cao believes that the world belongs to either himself or Liu Bei, and only he and Liu Bei are worthy of being heroes. This means that if you and Liu Bei become heroes, I will kill you, so that the world belongs to me alone.

This is what Cao Cao said to Liu Bei when Qingmei was making wine and discussing heroes. It means that Cao Cao believes that the only real heroes in the world are him, Liu Bei, and me, Cao Cao, which means that in the future, it will be the two of them who will compete for the world

The only heroes in this world are you and me. It means that the people fighting for the world in the future are you and me. So after hearing this, Liu Bei was so scared that he even dropped his chopsticks because Cao Cao would kill him. So Liu Bei ran away immediately after returning home.
