The iron gate on the street cut off Dongfang Gang accidentally triggering the "play within a play" infinite flow space, and was forced to enter various parallel copies of the ancient city. With the "emotion collection/exchange system", he collects emotional values such as laughter, curses, tears, and joy by playing tricks and making jokes, and exchanges them for secrets of the world, market intelligence, and even hidden props in copies. From cracking street scams to disrupting the Fireworks Tower gambling game, from sneaking into the imperial examination room to be the "question king" to resolving the escort crisis for the escort bureau, the funny male protagonist turned against the villain in the absurd copy, gradually uncovering the secret connection between the "play within the play" space and the city owner of Thousand Plays City, and finally used "laughter" as the blade to rewrite the rules of the system.
