Civil engineer Lu Chen woke up and transformed into the poorest good-for-nothing baron in another world. The territory is called "Ashes Corner", and it lives up to its name - the land is scorched, the water sources are depleted, more than half of the people starve to death, and even the farmers next door are disgusted. What's even more desperate is that this world believes in the supremacy of magic, and any technology that does not rely on magic is regarded as "evil." In the first three months, one third of the people will starve to death. Lu Chen looked at the half bag of coarse grains and a pile of scrap drawings left in his hand, and made a decision: not to cultivate immortality, not to practice martial arts, but to engage in infrastructure construction. Repair canals, burn brick kilns, improve farm tools, build fortifications... When the lord next door invades on a magical beast, he is greeted by concrete city walls, hydraulic trebuchets and a precisely calculated blasting bomb. When the Magician Association threatened to eradicate "evil technology", Lu Chen's territory had already lit up street lights, connected to running water, and built the first engineering college. What's even more surprising is that the slave girl he rescued turned out to be an exiled princess of the elves - she knew magic, he knew science, and the two of them joined forces to make the entire continent begin to doubt life.
