Xu Jing was a housekeeper before she wore the book, but she became a mirror with a gold finger after wearing the book.
The thing that tricked her was either a human or a ghost, and she was given homework to find the truth.
At first, Xu Jing thought she had found the truth. The emperor was an infatuated person who was willing to sacrifice everything for his sweetheart.
Later, Xu Jing thought that she had mistaken the emperor's attributes. He was not a pitiful person, but an aspiring young man who was determined to make progress.
Only in the end did Xu Jing understand that if her homework was a test paper, her score should be zero.
Because the truth she thought was actually not even close to the truth.
The emperor is not an ambitious young man, he is just a white-blooded person, a good actor, who deceived Xu Jing into a fool, and after the show, she said with a sympathetic look on his face that he was really pitiful.
She even got his sweetheart wrong.
