Cheating in the Great Tang

With a heart as broad as the heavens and earth, I ride wherever swords and spears lead me. Having witnessed the heroes of ages past, I alone claim the carefree glory of ten thousand generations. What legend will be left behind if I give the mighty Tang a cheat? Why should the Turks be allowed to throw their weight around? Why should Tubo come demanding a marriage alliance? How dare Goguryeo boast so shamelessly? Why is the Tang Crown Prince always beset by misfortune?
