Building a Viking Empire with Modern Industry-Chapter 61: Blueprint

Ragnar, sat in his private study. The conquest of East Anglia was over, the "merger" was complete, and the grain shipments were flowing north.

He had been working on this project in the late hours of the night, between audit reports and managing King Horik’s tantrums. It was his magnum opus. It was the solution to the biggest problem plaguing the Jernheim Corporation: Success.

York was bursting. Thanks to the agricultural reforms, the population had exploded. Thanks to the factories, thousands of peasants had flocked to the city for jobs. The result? York was no longer a city; it was a refugee camp with a GDP.

The streets were crowded with mud and waste. The wooden longhouses were packed so tight that if one caught fire, the whole city would vanish in an hour. It was efficient in terms of density, but catastrophic in terms of hygiene.

"We are suffering from success," Ragnar muttered, dipping his quill in ink.

He looked at the blueprint. It wasn’t a map of York. It was a map of a new location—a flat, defensible plain near the river confluence to the south.

He wrote the name at the top: PROJECT TITAN.

Ragnar tapped the paper. The first component was Sanitation.

"A worker with dysentery is a liability," Ragnar whispered to himself.

He sketched a grid of underground tunnels. The Cloaca Maxima. He planned to install a city-wide sewage system using vitrified clay pipes that would flush waste downstream, far away from the water intake. He also sketched a series of cisterns and sand-charcoal filtration beds. Clean water in. Waste out. It was a concept so simple in the 21st century, but god-like in the 9th.

The second component was Housing.

No more wattle-and-daub. No more thatch roofs that housed rats. Ragnar sketched multi-story buildings. The Barracks. They would be built of fired red brick—a material that didn’t rot and, more importantly, didn’t burn.

"Standardized living units," Ragnar mused. "Four families per floor. Central heating via hypocausts connected to the factory waste heat."

The third component, and the one that made Ragnar grin, was Defense.

The medieval castle was dead. Ragnar knew this because he had killed it himself at Thetford. High stone walls were just targets for trebuchets. Wood was kindling.

He drew a shape on the paper. It was a Star. The Star Fortress.

It was a design from the Renaissance, specifically engineered to deflect cannon fire (or in this case, Torsion Spike bolts and trebuchet stones). The angled walls deflected impact. The protruding bastions eliminated blind spots, allowing the defenders to create a "kill zone" of crossfire against anyone foolish enough to attack.

But Ragnar wasn’t going to build it out of stone blocks. That took too long. He wrote a note on the margin: Reinforced Concrete.

He planned to use the "Roman Cement" formula he had recovered, mixed with crushed granite, and reinforced with iron bars. It would be a bunker. An immovable object.

Finally, the Roads.

He drew straight lines radiating from the city center. The Arteries. Paved with macadam—layers of crushed stone compressed until they were hard as rock. These roads wouldn’t turn to soup in the winter. They would allow his heavy wagons to move supplies at triple the speed of a Saxon cart.

Ragnar stood up, stretching his back. The plan was solid. The math worked. Now came the hard part: convincing the workforce to build it.

Ragnar walked through the industrial district on his way to the Foundry. He didn’t take a horse; he needed to see the problem up close. It was disgusting.

The mud was ankle-deep. The smell of unwashed bodies and open latrines fought a losing battle against the acrid smoke of the blast furnace. Children played in puddles that were definitely not just rainwater.

"Director!" a worker shouted, tipping his cap. The man looked exhausted, his face grey with soot.

"Good shift, Arne?" Ragnar asked.

"Aye, Director. But the roof of my hut leaked last night. My kids are coughing."

Ragnar nodded grimly. "We will fix it, Arne. Hold the line."

He walked faster. He felt a desperate urgency. He had the money—Guthrum’s treasury had seen to that. He had the labor thousands of Danish prisoners. But he needed the materials.

He reached the Foundry. The heat hit him like a physical blow. The roar of the bellows was deafening.

Leif the Smith was standing over a vat of molten iron, shouting at an apprentice. Beside him stood Cedric the Saxon (Minister of Infrastructure), looking at a pile of gravel with a critical eye.

Ragnar strode in, waving the blueprint. "Stop the line!" Ragnar ordered playfully (though the line never actually stopped). "We have a new project."

Leif wiped sweat from his brow with a leather apron. "Another one? We just finished the plowshares for East Anglia, Director. The molds are still hot."

"This is bigger than plows," Ragnar said, slamming the blueprint onto a workbench.

He pointed to the diagram of the Star Fortress.

"I need pipes," Ragnar said to Leif. "Thousands of yards of them. Cast iron. Coated in bitumen so they don’t rust."

Leif blinked. "Pipes? For what? A giant flute?"

"For poop, Leif," Ragnar corrected. "I want to move the city’s waste underground."

Leif stared at him. "You want to use good iron... for dung?"

"It is the highest priority," Ragnar insisted. "And I need bars. Long, thin iron rods with ridges on them."

"Rebar?" Cedric asked, his eyes widening. He had seen similar iron clamps in the old Roman ruins.

"Exactly," Ragnar nodded to the Saxon. "We are going to pour rock. Liquid rock."

Ragnar turned to Cedric.

"Cedric, I am authorizing the budget for Project Concrete. I want you to burn limestone. I want you to crush volcanic ash. I want a slurry that sets underwater and dries harder than granite."

Cedric looked at the blueprint of the Star Fortress walls.

"If we mix the iron rods into the liquid rock..." Cedric whispered, visualizing the physics. "It would have the compressive strength of stone and the tensile strength of metal."

"Precisely," Ragnar grinned. "We call it Ferro-Concrete."

Leif looked at the blueprint, rubbing his bearded chin. He saw the sheer scale of the iron required. It was madness. It would consume the entire output of the mine for six months.

"Director," Leif said heavily. "This is... expensive. We could build ten thousand swords with this iron. We could armor an entire fleet."

Ragnar clasped Leif on the shoulder.

"Leif, my old friend. Swords win battles. But plumbing? Plumbing wins civilizations."

He pointed to the door, toward the crowded, smelly city outside.

"Do you want your children to grow up in the mud? Or do you want them to live in a city of stone and glass, where the water runs clear and the walls cannot be breached?"

Leif looked at the blueprint. He looked at the Star Fortress, with its geometric perfection. He imagined a city that didn’t smell like a latrine.

He sighed, a smile tugging at his beard.

"Iron pipes for dung," Leif chuckled. "The Gods will laugh at us."

"Let them laugh," Ragnar said. "They sleep in the clouds. We sleep in the mud. I prefer the clouds."

Leif slammed his hammer onto the anvil. "Alright!" Leif roared to the foundry crew. "Change the molds! No more swords! We are making tubes! And rods! Lots of rods!"

Ragnar turned to Cedric.

"And you, Minister of Infrastructure? Can you build me a Star?"

Cedric looked at the diagram. For a Saxon former slave, this was the opportunity of a lifetime. To build something that would outlast the Roman Empire.

"I will need timber for the forms," Cedric said, his mind already racing. "And ash. Tons of ash."

"You have the East Anglian forest," Ragnar promised. "Clear it."

"Then I will build you a mountain," Cedric vowed.

Ragnar rolled up the blueprint.

"Good," he said. "Breaking ground is on Monday. I have to go find Helga. I need her to figure out how to waterproof a basement."

With that, Ragnar left the heat of the foundry and walked back into the cool air.

He looked south, toward the empty plain where the rivers met.

"Just a few more years," Ragnar whispered to the wind. "Just hold on a little longer."
