Northern Blacksmith

Lin Yuan was a military engineer in his previous life and worked in steel all his life. In this life, he traveled to another world and was thrown to Beifeng Castle to die when he opened his eyes. The city walls were collapsed, the stoves were cold, and dozens of people were so hungry that they were chewing tree bark. No system, no magic, no backing. But Lin Yuan knows how to make iron. Bellows too backward? Change. Can't get the furnace temperature up? Water-powered forging hammer. The robber next door comes to rob? Queue to be shot to find out. While others were still fighting with magic, he had already repaired the city wall, grown food, and built a steam engine. The orc veterans surrendered, the dwarf blacksmith knelt down, and even the elf princess stayed behind. The empire sent a large army to suppress it? Thirty thousand versus three hundred? Lin Yuan said: You are here, just stay and work. This is not a story about a hero saving the world. It was an honest man who, with a group of people who wanted to have enough to eat, used the stupidest method - work hard, help each other, and don't bully others - to build the poorest place into the richest city. As for recruiting a few girls, fighting a few good fights, and changing the rules? That's all by the way. Here, whoever has a big fist may not be able to use it easily, but whoever follows the rules will be able to eat well.
