There was no denying Gong Qinghua's rise to the throne. With the Imperial Court facing foreign invasions, there was no room for internal disputes. Thus, Gong Qinghua made Gong Zixuan the King Ding.
Shangguan Wanru felt uneasy, thinking the two had put their past grievances behind them a bit too easily. However, Gong Zixuan impatiently retorted, "What should we do then? Have us brothers fight to death and let Minze Country reap the benefits?"
Upon hearing this, Shangguan Wanru dared not utter another word. She couldn't help but feel a bit guilty about Minze Country's invasion of Nangong Country - it was her homeland after all.
So that's why Li Guzi now addressed them as King Ding and Princess Ding.
