All that glitters is not gold
Well... To be fair, Liu'er did forget something rather important. Not that Bai Yue was any better. They both got pretty distracted by the rest of their conversation. Moreover, the news wasn't anything Bai Yue didn't expect. In her past life, the Dowager Empress also sent a decree to invite her into the palace for a first meeting. With Bai Li An here to act as a substitute, it made sense for Madam Fu to seize the opportunity and make the girl go receive the decree in Bai Yue's stead. As for the Crown Prince, her father was currently working with him to investigate Ji Mo Zhen so it wasn't that much of a surprise either.
Noticing Liue'er's expression, a helpless expression came over Bai Yue's face and she swallowed her laughter. "You were talking about the Crown Prince and the imperial decree before I started teasing you. Which one sounds more important to you right now?"
