You Idiot in the Prime Minister's Office, I'm Pretending to Be Crazy and Acting Stupid in the Capital

In the Zhou court, Shen Qinghuan, the legitimate daughter of the prime minister, has been a foolish person since she was a child. He drooled all day long, talked nonsense, and walked crookedly, becoming a laughing stock among the ladies of the capital. But no one knows that this "silly" eldest lady of the prime minister's house is actually a genius. She pretended to be crazy and stupid for fifteen years just to avoid her stepmother's plot and to survive in this deep compound. Shen Qinghuan knows one thing very well: in this world, no one will be wary of a fool. Because of this, she was able to secretly collect the clues of various dignitaries in the capital and master the secrets of the court. Now the time has come for her to tear off the mask she has been hiding for many years and use her intelligence and talent to make those who once laughed at her pay the price.
