Yingjiang: "You, the Dragon Kingdom, don't respect martial ethics, so dismantle my satellite's solar panels!" Mao Xiong: "We have always been friends in the Dragon Kingdom, please take back the nuclear-powered tanks!" Pickles: "You won't believe it if I tell you, our White Tiger Regiment was gone as soon as we arrived on the battlefield!" Sakura: "Do we still have a chance?"
