率更丞王秘密禀告李世民说： 太子对齐王说： 现在，你已经得到秦王骁勇的将领和精悍的士兵，拥有数万人马了。我与秦王在昆明池为你饯行，让勇士就在帐幕里摧折秦王的身体，将他杀死，上奏时就说他暴病身亡，皇上该不会不相信。
率更丞王晊密告世民曰： 太子语齐王： 今汝得秦王骁将精兵，拥数万之众，吾与秦王饯汝于昆明池，使壮士拉杀之于幕下，奏云暴卒，主上宜无不信。
The Secret Secretary of the Ministry of War, Wang, secretly informed Li Shimin, saying: The Crown Prince said to the King of Qi: Now, you have gained the brave generals and elite soldiers of the King of Qin, and have tens of thousands of troops. The King of Qin and I will hold a farewell banquet for you by the lake of Kunming, and ask the warriors to cut down the King of Qin's men in the tent and kill him. When reporting to the Emperor, they can say that the King of Qin died of sudden illness. The Emperor would not doubt them.
