The Emperor of Yuqi and Empress Dowager are competing for power in the country. Si Wuyan, the daughter of the Emperor, has been disguised as an assassin and has tried to steal gunpowder from the Empress. The Empress tells her that she is here to tell her not to interfere with the internal affairs of the kingdom. The Emperor is angry to learn that the prince Qi is in Yuqi, and he will not allow the prince to use gunpowder in the war. He also tells her to leave quickly so that he can return to his own kingdom. Three days later, the prince returns to the palace in a carriage arranged by the Empress, who stipulates that the imperial forces must not interfere in the internal war. If they want to help Siwuyan, they must use gunpowder. Otherwise, they would have to break their deal with the Prefecture Chieps mansion. He tells the Empress that he has heard that the "heinous princess of yuqi" instigated the war and should be executed. He says that he does not care what other people think of him. He wants to stay with her forever, and she tells him that they need to try new gestures. She says that the Emperor sent an urgent message to her, and that he must have sent it for a reason. She tells him to go back and look at the situation. The drug drives the people to kill, and once they leave, the people will definitely go back to nearby towns and slaughter people.
