Lu Yangming traveled to a different world and woke up to find that he was a beggar who was about to starve to death. This world is extremely short of resources, and nobles can start a war just for a piece of iron ore. By chance, he exchanged a discarded E-Lady for a steamed bun from a child. At that moment, he suddenly realized that the modern world he came from was full of "treasures" that were unheard of in this other world: plastic bags were thinner and tougher than silk, Elagian was a rare metal that never rusted, mineral water bottles could be made into the sharpest arrows, and even a piece of broken glass could be ground into gems that nobles were eager to collect. Three months later, Lu Yangming rose from being a beggar to becoming the richest man in the capital. A year later, his caravans monopolized trade across the continent. When the king finally couldn't hold himself back any longer, he sent someone to secretly track the source of his goods, only to find that this mysterious businessman was just rummaging through the garbage dump outside the city, and there were countless "treasures" in his eyes.
