When the fight is over, chen-qin tells his brother that he thinks he's strong enough to beat yi-zhang, but that his brother is going to lose, so he'll have to take the fight to him. Aww, that's kind of like saying, "Hey, I'm going to kill you, but you're going to have to kill me, too" . He's a little worried about that, but he doesn't want to kill his brother. He tells him that he can beat any of the other four princes, and that the crown prince will definitely help him.
