I Synthesize Everything in the Wasteland

In the world after the catastrophe, materials are extremely scarce. Song Xiaozhu holds an item synthesizer and turns waste into treasure under the garbage mountain. He accidentally becomes rich and powerful. What, a lumberyard needs an ax? Synthesizer recipe: [Wood Raw Materials] + [Stone Raw Materials] = Simple Ax. Song Xiaozhu: "There are 3,000 of them here. Let's use them first." What, the beast tide is coming and we need weapons? Synthesizer recipe: [Wood Raw Materials] + [Iron Raw Materials] = Simple Steel Knife. Song Xiaozhu: "Is ten thousand enough? If not, there are still one hundred thousand." What, the villagers have never eaten meat? Synthesizer recipe: [Contaminated Beast Meat] + [Antidote] = Fresh Meat. With a wave of Song Xiaozhu's hand, he served barbecued beef with meat sauce, braised pork ribs, pork trotters and knuckles, and the villagers were moved to tears from the corners of their mouths. And later... Do you need a strong army in troubled times? [Corpse] + [Energy Stone] = Undead. [Undead] + [Copy Chip] + [Super Energy Stone] = Undead Army. Behind Song Xiaozhu was the army of the undead, and in front were heavy weapons and black technology light shields. She faced the intruders with a smile: "... Are you still fighting?" Purpose: The perseverance of human nature in difficult circumstances
