"First, you must insist that this batch of grain is the private property of your Yelu Family. When the time comes, heh heh, you use the court's Black Cavalry to transport private grain for yourself, only to be discovered by the Commandery Princess. The Commandery Princess then has the right to report post-killing, and deal with you harshly."
"Moreover, this batch of grain will still end up in the hands of the Commandery Princess."
"There's another path the Commandery Princess has arranged for you. Didn't she hold a rally a few days ago? At that time, all of you expressed your desire to find ways to alleviate the Commandery Princess's worries and sought to gather grain to solve the grain shortage in Mianshui!"
"Well, now this batch of grain is what Lord Yelu has procured to alleviate the Commandery Princess's worries. You, my lord, are a greatly loyal minister, remembered by both the Commandery Princess and all the townsfolk as a good person."
