Su Chengyu listened to this unexpected answer, raising his head in surprise and looking at the other person with confusion.
The Green Hillock Empress reached out with her jade-like hand to touch Su Chengyu's face, softly saying, "Your grandfather's departure was destined. Even if Yang Chengyin hadn't acted back then, he would have inevitably temporarily disappeared from the Capital City, with perhaps only his name not being erased."
"Then what about Yang Chengyin—"
"The Xia Country was the fallback plan he left for himself. After doing that thing, whether he succeeded or failed, with the Xia Country there, your grandfather had room to retreat. Yang Chengyin knew this, so he acted at that time to brand him as a so-called traitor."
