Nanjing, 1937, purgatory on earth. The bookworm Chen Mo watched his father, a locksmith, stabbed with a Japanese bayonet. Before his death, his father gave him not a gold bar, but half a code book and a strange picture. Escape? Where can I escape! Meeting Feng Yue, a nurse who dared to light explosives to save lives, and an old blacksmith who had been pretending to be mute for twenty years, the three "waste" formed a strange team. Chen Mo used a welding gun to turn broken copper and iron into a radio in his hand, Feng Yue changed the first aid kit into an explosive kit, and the old iron muffled to build hidden grids and pontoon bridges. Major Miyamoto's direction-finding vehicles were all over the city, vowing to find this "electric rat." "Hey, are you coming to catch me?" After Chen Mo sent the last message, he detonated Feng Yue's "Kaiselu Mixing Detonator" buried in the granary. From the ruins of Jinling to the beacon smoke in the southwest, the three of them used their "imagination" and "craftsmanship" to weave a large network: passing on top-secret intelligence, specializing in bombing the enemy's vital points, and opening up life channels! Who says little people can't stir up the storm of war? A secret message and half a picture, the fire of faith ignited by a group of "waste" will eventually burn through the night!
