In an imaginary and chaotic era of dynasty replacement, Xu Sanduo, a small town gangster, wanted to eat and die, but was dragged into a power vortex. He was forced to form a "nonsense squad" with the daughter Su Xiyu who disguised herself as a man, the retired bandit Liu Gaizi and the mysterious boy Lu Mo. They accidentally uncovered conspiracies, played tricks on powerful officials, witnessed friendship, love and growth in troubled times, and also revealed their own unknown secrets. The whole book uses humor as the background, telling the fate of small people under the shadow of swords, making jokes along the way, and finally using small and big things to rewrite the pattern of troubled times.
