The writing is sloppy... Maybe some of the history has been changed...
This is the story of a history girl who traveled to the Three Kingdoms in order to complete her graduation thesis. She brought her [Counselor] skill to the full level, and decided to be loyal to [Yuan Shu] by chance, assisting this scumbag lord in returning to the historical stage of the Three Kingdoms...
Of course, as a proper stepmother of the historical party, she will never let the heroine get her wish.
It's obviously too late
