At the end of the Daye Dynasty, war broke out everywhere. The northern separatist forces raised their troops and moved southward, and the people were displaced. Lin Dou, the son of an ordinary blacksmith, was involved in the rebellion. He repeatedly averted danger with his humorous eloquence and clever tricks. He teamed up with the greedy and timid Wang Pangdun, the scheming female general Xiao Qingzhi, and the grumbling poet and strategist Meng Shunzhai. In the gap between "laughing" and "war", he experienced countless absurd, thrilling and hilarious life-and-death moments. They grew from cannon fodder to heroes in troubled times, using alternative methods to promote the war situation. In the end, Lin Dou faced Xiang Cui Ce, the idealistic villain of the "Perfect World", and not only defended his home, but also allowed laughter to persevere in the flames of war. The book uses a humorous and compact rhythm to show the warmth, growth and heroic qualities in the background of war.
