Xu Yin stood waiting with lowered eyes for a while, then said, "Although this incident came suddenly and caught us off guard, ultimately, Prince, your meticulous planning back in the day left no future troubles. Even if someone discovers some clues, it is of no major consequence. There is no need for you to worry so much. The Commandery Princess was quite frightened tonight, I shall take my leave first."
"Wait a moment."

Xu Yin stood still. "Please, Prince, ask whatever you wish."
Prince Rong stepped out from behind the curtain, his gaze deep under the lamp light, "Was it you who killed Liang Ning?"
