"How is the Lord of White Stone City doing now? Has he been replaced?" Du You had a good working relationship with the Lord of White Stone City, and if he was replaced, other problems might arise.
"The Lord of White Stone City has not been replaced. After all, he has been serving here for so many years. The Empire can't easily replace him, as it would cause dissatisfaction among other nobles and lords. However, the presence of a fourth-tier expert and a large number of third-tier troops has supposedly made the Lord's life very difficult recently."
Indeed, the Lord of White Stone City himself was only a third-tier individual who hadn't even reached the peak, or perhaps he had, Du You wasn't sure. But this level of power, combined with just a few subordinates, would not be enough even with a long tenure.
The people sent from above were too strong, and it would be very easy to sideline the Lord.
