In 762, seven years before the events of the novel, the prince of da-zhou asks why his son-in-law has killed him. The prince says that the prince is afraid of the kingdom's imperial blood and wants to return to his own capital to rule. He says that six years ago, he sent someone to check on the prince, but the prince didn't kill him. This is the only way to save the prince's life, says the prince. He tells the prince that he has withdrawn assassins from the area where the prince lives, and that he tried to escape from his father, but that dream will not come true when they go to meet his older sister and seek her help. He asks the prince why he has killed himself, and the prince replies that he wants to unite the north and pacify the world, but he cannot do so without the support of his father. He adds that he cannot make great things without the father's support, but perhaps the hysteria of the prince has already gone, and she has not changed her first goal, until now. She has always wanted a great career, he says, and it is time for her to execute immediately. He reminds the prince and his men that the one to blame is the prince who is clinging on to life and fears death, and he reminds them that he is goodhearted and does not fear death. They ask the prince to help the lieutenant general get the prince so that they can cancel the order to kill the prince
