Zhuge Liang through Lu Su tries to goad Zhou Yu into a fury, telling him that he is only capable of battle on water, and not on land. When Lu Su unwittingly tells this to Zhou Yu, he is, indeed, infuriated and orders Lu Su to take back the token of authority [which Zhou Yu has given to Zhuge Liang]. Zhou Yu wants to go north of the river to meet Cao Cao in battle. Lu Su tries to get hold of the token, but Zhuge Liang refuses to give it away. He makes an agreement with Lu Su that he will do a great deed for his commander.
諸葛亮用話激動魯肅轉激周瑜，說周瑜只能水戰，不能陸戰。魯肅無意將此話告訴周瑜，周瑜大動其怒，命魯肅把令箭收回，自己到江北與曹操交戰。魯肅來要令箭，諸葛亮不把，諸葛亮跟魯肅談定，我替你家都督另辦一件大事。
