Upon hearing this, Duke Li Guo said sternly, "Empress Dowager, please rest assured. Even if Lady Mu were my grandson's wife, or even my grandson himself, if they had violated the national law, I would never shield them."
At that moment, the day had already broken. Nangong Yi and the ministers hadn't slept through the night, so he ordered them to rest first, while he and Duke Li Guo continued investigating Nangong Yu's case. Empress Dowager Mo, however, refused to return and insisted on following them in the investigation. She repeatedly declared that if anyone tried to shelter the criminal, she would stop at nothing, even if it led to mutual destruction, to avenge her daughter.
As she spoke, her eyes were fixed on Fei'er, as though she had already determined that Fei'er was the murderer of Nangong Yu.
