Which authors were good at describing mechanisms, secret codes, and secret chambers?

According to the given novel information, the following novelists were good at writing mechanisms, secret codes, and secret rooms: Black Horse River, Mo Jiu's keen mechanism thinking in "The Lonely King and Widow Daughter"; The Firefly Between the Feet, the dense puzzle-solving plot in "The Secret Room Can't Escape";; The rumor of the young master, the weaving and inheritance of the mechanism network in "Jinling Machine Master", etc. The above is my personal recommendation.
