Zhao Che, a modern engineer, travels through time and becomes the emperor of the Yan Kingdom. The moment he opens his eyes, 100,000 Northern Wei cavalry troops are already bearing down on his borders. He binds himself to the "Empire Industrial Revolution" system and starts with a kiln of cement and a single steel ingot, going on to smelt steel, cast cannons, build trains, establish a navy, and lay railways. From defending cities to conquering kingdoms, from land battles to naval warfare, he crushes every enemy with the power of industry. Ultimately, he establishes a world alliance and makes Yan the nation that sets the rules for the world.
