The male and female protagonists both traveled through time and became a cowardly king and a demon queen.
There are the Prime Minister's gang members in front of the court, and the Queen Mother is watching covetously in the back.
There are tiger's dens in the front and back, so let's just open a harem for the queen.
All the concubines and mothers were brought into the harem, and the eunuch looked very handsome.
The government was in trouble, the people were wasted, the money was wasted, and corvées and taxes were imposed all over the place.
Minister, is it hard? Give him a female secretary.
There are three thousand people in the harem, all of whom are students.
Who says women can't serve as officials?
Everyone in the world thinks it is absurd, but it has created a prosperous world for a hundred years.
