Ye Xuan, a top engineer who is frustrated in modern society. In an experimental accident, his soul traveled to a fantasy world of swords and magic, and he became a destitute baron on the verge of bankruptcy. In this world, magic is powerful and knights are majestic, but the level of technology remains in the Middle Ages. Famine, war, and ignorance are the norm.
There is no golden finger or system. Ye Xuan's only "plug-in" is the vast modern scientific and technological knowledge in his mind. He started from the most basic: improving farm tools to increase grain production; building a simple waterwheel to provide power; using coke to make iron and improving metallurgical technology. He brought modern industrialization concepts into the world and started his journey as an "infrastructure madman" from a barren territory.
He built the first steam factory, and the roar of the machinery shocked everyone who saw it. When his "Iron Chariot" ran over the Knights' defense line, and when his "Magic Crystal Cannon" destroyed the magician's barrier, the entire continent was shaken. He combined modern military theory with resources from another world, armed the army with standard weapons produced on the assembly line, used radar to detect magic fluctuations, and used airships for aerial reconnaissance and bombing. His technological power has caused a dimensionality reduction blow to this magical world.
Ye Xuan not only changed the shape of war, but also changed people's lives. He promoted public health, established schools, and even brought modern entertainment and art into other worlds, triggering an unprecedented cultural shock. He used the power of science and technology to allow ordinary people to live an unprecedentedly wealthy and civilized life, breaking the monopoly of knowledge and power held by nobles and magicians.
