Li You nodded slightly, a gentle smile on his face as he said, "The Crown Prince is absolutely right. However, to me, the heights of social ranks and the nobility or humility of one's status don't really matter. As long as there is mutual affection and harmony between the parties, it is enough."
The Emperor was highly pleased with Li You's performance, praising, "The Prince of Zhao, he's a child of great affection and righteousness."
Quite obviously with regards to these two sons, the Emperor's heart was beginning to tilt in favor of his illegitimate son.
The Crown Prince's excessive competence, his overt ambition, had already started to engender dissatisfaction and a sense of crisis in the Emperor.
He is a father, but he is an Emperor first.
As an Emperor, he would not tolerate anyone coveting the throne he sits on.
Even if the Crown Prince is the successor he himself had appointed.
It still wouldn't do.
