The promise of the Prince of Yundian was to devote the entire strength of Yundian.
He was the greatest vassal king in Great Yan, wielding real power. Even if he wanted to rebel and declare himself king, the Imperial Court was helpless. In the eyes of the locals, there was only one Emperor, and that was the Prince of Yundian, not an emperor yet akin to one.
The people of Great Yan also knew this, often secretly referring to him as the local Emperor of Yundian.
The sides were so harmonious only because the Yundian Royal Mansion lacked ambition; otherwise, it would have been the greatest trouble for the Imperial Court.
However, Jun Yuyan and Murong Jiu had never thought of exploiting the Prince of Yundian.
They rescued Xiao Wen, treated him well out of pure intentions, without harboring any ulterior motives.
As long as the Prince of Yundian was not exploited by other princes, that was enough.
After sending Xiao Wen away, Murong Jiu felt down for a couple of days.
