That year, Ling Xian just entered the Zhou Dynasty and came to a conflict with the Third Prince.
Then, he publicly attempted to kill the Third Prince, causing the emperor to personally attack him, thereby creating a rivalry.
Today, the Zhou Dynasty's emperor was badly beaten and he has lost all his face. The old rivalry came to a complete end.
Ling Xian believed that he had taught the emperor a great lesson. For the rest of his life, he believed the emperor would spend it in shame. This was harder on him than killing him.
Plus, after today, the Seventh Princess will become the new empress of the Zhou Dynasty. Even if this person cannot let go of this past, he wouldn't have the guts to attack Ling Xian.
Therefore, what's there to dwell on?
"I will stay here another day. Tomorrow, after the Seventh Princess is crowned, I will leave."
