Ye Yinzhu said, "Since I promised him, I'm not afraid that he'll spread the news. After all, he is your father, and I can vaguely guess his thoughts. By making Siqin the heir to the Landias Empire, not only can he win us over and gain the favor of Qin City, but he also essentially earns the support of Master Aubrey. By stirring up conflicts between us and the Milan Empire, or even causing rifts, Landias can survive more easily. My father-in-law probably knows that we'll guess his motives, but his smartest move is that even though we can guess it, we have no choice but to cooperate with him. After all, the holy war is more important than anything, and I will have to compromise with him to a certain extent. As for his earlier proposal to let you inherit the throne, that was just an outrageous initial demand, a strategy of bidding high and settling for less."
Sura stared blankly at Ye Yinzhu, "If you know all this, why did you agree to his terms?"
