After Regina came across those three members of the Blood Triangle Pirates, even though they were enemies, she had no choice but to direct them to Dry City.
They were powerful but did not seem to have bad intentions. At the same time, Dry City already had methods of dealing with people from the late 8th stage.
So even if it was dangerous and bad to deal with these people, she directed them to the local leaders, who could best solve the present situation.
Since Minos was not in the city, much less his wives, those three quickly arrived in front of Dillian and some Spiritual Saints from the Gray Clouds Sect.

In the imperial palace...
As usual, Dillian was taking over Minos' duties when no one else from the imperial family was in this city.
