The imperial decree only contained a single sentence!
As King Heavenspan, Bai Xiaochun is hereby formally appointed as the Saint-Emperor Dynasty's ambassador in Vile-Emperor City!!
Technically speaking, Bai Xiaochun would still be the king of the north in the second immortal domain, but for all intents and purposes, he would no longer serve in that role. He would be the official ambassador stationed in Vile-Emperor City!
Both imperial dynasties had ambassadors in each other's capital cities. Usually, they were demigods with long records of service, although occasionally celestials would also serve in that role.
Sima Yunhua was the former ambassador, except that he didn't actually visit the Vile-Emperor Dynasty very often. Most of his time was spent in Saint-Emperor City.
Unfortunately, Sima Yunhua had been wounded in the fight with Celestial Virūpākṣa, so whether he wanted to or not, his responsibilities were being transferred to Bai Xiaochun!
