Please recommend a transmigration novel. The main character's name is Li Suying.

The protagonist of the novel is Li Suluo. She is a cold-blooded secret agent who transmigrated to a prime minister's residence and became a weak third miss. Later, she solved all kinds of obstacles one by one, and her strength soared. She countered every move she saw, killing one when one came, and killing two when two came. I hope you like this fairy's recommendation. Muah ~😗
