The daughter raised by a Taoist, she learned the art of observing people at the age of three, and at the age of fifteen she took the initiative to marry the most useless good-for-nothing prince in the entire capital.
Others thought she was the loser, but she knew that "trash" was the last person to turn over the cards in the whole game.
She has no medical skills, no superpowers, and no space - she can only see people. See who is lying, see who cannot last three months, see where the cracks in a dynasty begin to break.
The useless prince ascended the throne and she became the queen. She saw through every woman in the harem who smiled and handed teacups.
There was only one person whom she could not always see through - the man who had passed away from the imperial examination incognito, the man who had grown up with her and walked in silence for twenty years.
