Topic: Pang Gang returned to the sad eighth year of Chongzhen in the Ming Dynasty, and the world was in great turmoil. Li Zicheng made chaos inside, and the Manchu Qing invaded outside. What should this buddy from urban management do? Is he following the trend and waiting to welcome the Manchus? The invasion of the Tartars still needs to pick up a kitchen knife to resist? Uh, wait, didn’t you say that every buddy who travels through time has a golden finger? Where is the buddy’s golden finger? Oh! Damn it turned out to be 'Modern Weapons Encyclopedia' ? But I'm just an urban management not a fitter! Who can tell me how to make this gun! Ordinary group: 52877079
