Copy 150 Howitzers at the Start

Lin Chen traveled through a different world. You get the copying hand at the beginning. In a world where warlords are fighting and foreign enemies are invading, having a gun is king. If you don't have a gun, just copy it, you already have a rifle and a machine gun. If you don't have cannons, just copy them. Mountain cannons, howitzers, and field cannons are all available. If there are no planes, then copy. If there are no tanks, then copy. In a world where human life is as important as mustard, with the hand of copying, everything is possible.
