In the middle of the battle, the prince asks the emperor to punish him for guarding the border and not returning to the capital for the rest of his life. The emperor tells him that the late emperor feared that the family would not be able to protect themselves in the future, so he hid an army in his mansion. The prince asks if the emperor is threatening him, but the emperor says that he is not threatening him. He tells the prince that they cannot trust each other, and that he will help the prince to guard his territory in future
