The treasury had been empty for a long time.
A new funeral required a lot of silver. The more they gave to King of You, the less they would use. They even had to pay for it out of their own pocket. Other matters could still be discussed.
When it came to money, no one was willing to harm their own interests.
Redoing the funeral was also a laborious effort. Logically speaking, it should be done according to the rules of the imperial prince.
But!
First of all, King of You was a good general who had contributed greatly. There had always been a precedent of the Great Zhou Dynasty conferring titles to heroes.
His Highness King of You was already a imperial prince. If he were to be conferred the title of nobility, it would be equivalent to the title of regent. All funerals had to be arranged according to the title of nobility after the conferment.
