At court in the Great Liang dynasty, eighteen-year-old Princess Xiao Yueyin smashed the precious jade scepter presented by Chancellor Zhao Chongyuan in front of all the civil and military officials. “I don’t like people playing games in front of me.” The entire court was in an uproar, but no one dared speak. After the session, the emperor summoned her and appeared to scold her, though his real intent was to warn her: “Your temper will get you into trouble sooner or later.” That night, Xiao Yueyin was attacked. Her personal maid died saving her. The emperor ordered the Shadow Guard Battalion to send more men, and its commander, Anying, dispatched its strongest operative, Yun Gui, to protect the princess at all times.
