When orcish hooves shattered the southern plains, and infighting among nobles eroded the kingdom's foundations, Ryan Green, from another world, inherited the remote Eaglebeak Valley. Here, there was no fertile land, no loyal army, only a group of serfs struggling to survive and crumbling city walls.

In chaotic times, survival is the only rule. Ryan knew that relying solely on cold weapons and feudal constraints would ultimately reduce him to food for orcs or a pawn in the power struggles of nobles. He took up two "weapons": steam and gunpowder.

He used steam engines to drive forging hammers, stamping out indestructible iron armor; he used sulfur and saltpeter to develop cannons that shook the battlefield. He broke the aristocracy's monopoly on knowledge, teaching soldiers to read and navigate, and had serfs cultivate land and train soldiers, building an iron defense line in barren valleys.

Faced with the savage charges of the orcish legions, he constructed death traps with giant ballistae and gunpowder mines; dealing with the nobility's attempts to win him over and their schemes, he accumulated wealth by exporting iron armor, demonstrating the confidence of "neutrality" through his strength. From being forced to defend to actively expanding, from an unknown lord to Earl Green, he proceeded step by step, transforming a remote valley into the only safe haven in a chaotic world.

As the northern nobles' rebellion tore the kingdom apart, and as the eastern orcs brewed an even greater storm, Ryan stood before the steam-powered workshop, gazing at the armored army arrayed in formation, his eyes gleaming with ambition: "Chaos is not the end, but an opportunity to reshape order. This southern land will ultimately be dominated by steel and steam."

This is a story about using technology to break the shackles of feudalism and using strength to rise in a chaotic world.

A game called Civilization Wars suddenly appeared. Players create civilizations step by step from scratch. In the game, players can establish city-states, develop their civilizations, advance technology trees, and deploy troops. Li He entered the game as a tribal chief. He experienced the Stone Age, the Feudal Dynasty, and the Industrial Empire... He thought everyone was simply progressing steadily through the technology trees and civilizations, but who knew... what are these orcs, elves, goblins, and dwarves?! Didn't everyone start as primitive humans eating raw meat and drinking blood?

Lu Chuan, a modern civil engineer, unexpectedly transmigrates into the body of a deposed prince exiled to a barren land. Faced with saline wasteland and a desperate populace, he vows to create life in this desolate place. He gains trust with a shallow well, defeats a village bully with fishing traps, and discovers astonishing mineral deposits in the barren mountains. When powerful external enemies lurk, Lu Chuan uses his extraordinary wisdom to lead his people to independence. Caravans come and go, brick kilns rise, and disillusioned martial artists lend a helping hand; he embarks on an unprecedented path of infrastructure development in this wild land.
