Chapter 25: The Sempoa and the Iron Bleed

The sun rose over Dian Village, casting long shadows over a settlement that no longer felt like a refugee camp, but a booming industrial zone. The air rang with the sound of iron striking stone, the shouts of foremen, and the rhythmic thud of falling timber.

Inside the Administrative Headquarters, Takuya sat at his desk, his eyes bloodshot. He had been awake since Inori left for the Zephyr Forest, drafting the military blueprints that would keep them alive.

Scattered across his desk were complex schematic drawings. One was for a Ballista—a massive, mounted artillery weapon. Takuya meticulously detailed the “torsion bundles,” thick coils of tightly wound animal sinew and rope that would provide the kinetic energy to launch heavy spears.

Next to it was the design for the Mechanical Bow, the crossbow. Takuya sketched the internal trigger sear and the rolling nut mechanism. But as he stared at the horizontal prod—the part of the bow that bends—he ground his teeth in frustration.

“Useless,” Takuya muttered, tossing his charcoal pen down.

If he forged the prod out of the standard wrought iron they currently possessed, it would suffer from plastic deformation. The moment a soldier cranked the string back, the iron would bend—and stay bent. It wouldn’t snap back. He needed Spring Steel, a specific high-carbon alloy tempered to have an immense yield strength. And he couldn’t make Spring Steel until Inori returned with the magnesite to build a hotter blast furnace. He had the designs of the future, but he was bottlenecked by the materials of the present.

Taking a deep breath, Takuya rolled up the blueprints. It was time to shift from engineering to economics.

He walked out of his private office and into the main hall. The ten members of the Audit Commission and the eight members of the Financial Bureau were seated at long tables, staring blankly at massive stacks of parchment. The first shipment of the Duke’s provincial ledgers had arrived before dawn via a fast-rider courier.

“Lord Takuya,” one of the auditors said nervously, holding up a dense ledger filled with thousands of handwritten numbers. “The sheer volume of these transactions… adding these up using standard stroke tallies will take us months.”

“If you use stroke tallies, yes,” Takuya said smoothly. He walked over to a wooden crate he had commissioned Silas’s carpenters to build overnight. He opened it and pulled out eighteen rectangular wooden frames. Inside each frame were vertical rods, and on each rod were sliding wooden beads divided by a horizontal beam.

He placed one on the desk in front of the nervous auditor.

“This is a Sempoa,” Takuya announced, distributing the devices to the completely baffled clerks. “A calculating tool from my… homeland. We are abolishing stroke tally counting today.”

Takuya walked to a large chalkboard Inori had installed.

“Look at your Sempoa. The vertical rods represent place values: ones, tens, hundreds, thousands. The beads below the horizontal beam hold a value of one. The single bead above the beam holds a value of five.” Takuya demonstrated, sliding the beads with a rapid clack-clack-clack. “To add, you move the beads toward the beam. To subtract, you move them away. Once you memorize the physical movement, your fingers will calculate faster than your brain can read the numbers.”

For the next two hours, Takuya drilled them. At first, the clerks were clumsy. But these were intelligent, literate people. Soon, the room was filled with the rapid, rhythmic clicking of wooden beads. Equations that would have taken five minutes on parchment were being solved in seconds.

“You are no longer just clerks,” Takuya told them, pacing the room as the beads clicked. “You are my auditors. When you look at these ledgers, I do not want you to just add the numbers. I want you to look for the ghosts.”

“Ghosts, my lord?” a female clerk asked.

“Ghost companies and money laundering,” Takuya explained, slipping into his ruthless CEO persona. “Corrupt men do not just steal gold; they hide it. Look for mercenary guilds that receive monthly payments but have no record of buying food or replacing armor. Look for merchant caravans that charge exorbitant transport fees for short distances. Trace the flow of the money. If a ledger doesn’t balance to absolute zero, flag it.”

Satisfied with their progress, Takuya left the headquarters to inspect the village.

The transformation outside was staggering. Silas and Hameel were orchestrating a small army of laborers. Near the eastern gate, a massive cloud of dust rose into the air as the abandoned wooden houses were systematically demolished. Usable timber was being stacked for the school, while the debris was cleared to make way for Kaguya’s sprawling, sterilized hospital complex.

Further out, along the perimeter, the “Water Lock” moat was taking shape. Men covered in mud were swinging heavy iron picks, digging deep into the dense clay and striking the solid bedrock beneath.

“Lord Takuya!” Silas called out, wiping sweat from his brow. “We’ve hit the bedrock on the eastern flank. It’s hard going, but if the Dwarves try to tunnel under this, they’ll flood their own mines just as you predicted.”

“Keep digging, Silas,” Takuya ordered. “The deeper the trench, the safer we sleep.”

Takuya spent the rest of the day moving between the construction sites, optimizing labor lines, and ensuring the agricultural expansion was on schedule. By the time the sun set, his muscles ached, but the village was functioning like a well-oiled corporate machine.

Returning to the Administrative Headquarters late that night, the building was silent except for the rhythmic clack-clack of a single Sempoa.

The lead auditor was standing over the master ledger, his face pale in the lamplight.

“Lord Takuya,” the auditor whispered, his voice trembling. “I found the ghost. I found the bleed.”

Takuya immediately moved to the table. “Show me.”

“It’s the iron ore extraction reports from the northern hill mines,” the auditor pointed a shaking finger at the columns. “According to the mining overseer’s logs, they extract exactly one hundred tons of raw iron ore every month. But when I cross-referenced it with the provincial armory receipts in Suebic Town… the armory only receives sixty tons.”

Takuya’s eyes narrowed. “Forty tons of iron missing. Every single month.”

“I thought it was a recording error,” the auditor continued, frantically sliding the beads on his Sempoa. “But I traced the transport guild responsible for moving the ore. They are charging the Duke for the transport of the full one hundred tons, but their wagon weight logs only account for sixty. The remaining forty tons never make it to the Duke’s armory. They are being diverted at a crossroads town.”

Takuya leaned over the ledger, tracing the signatures authorizing the transport guild. “Who signed the ledgers for this specific guild?”

“Two men, my lord. Baron Luthor and Viscount Hadrian Kestrel.”

Takuya recognized the titles from his previous political briefings with the Duke. His corporate mind rapidly began putting the pieces together.

“Luthor and Kestrel,” Takuya murmured, staring at the numbers. “They don’t belong to Duke Matthew’s inner circle. They belong to the rival faction. They are sworn to Earl Cedric Thalwyn.”

The political reality crashed down on Takuya. The Kingdom of Cynthia wasn’t just fighting the Dwarves; it was eating itself alive from the inside.

“Forty tons of iron a month doesn’t just disappear,” Takuya said, his voice dropping to a lethal whisper. “You cannot hide that much metal. You have to sell it. But to whom? If they sell it back to the Cynthia Kingdom, the Duke would notice the surplus.”

Takuya looked up at the massive world map pinned to the wall. His eyes traced the border from the northern mines, past Cynthia, straight to the deep woods of the west.

The Elves.

“My god,” Takuya breathed, the sheer scale of the treason making his blood run cold.

Earl Cedric Thalwyn’s faction was actively undermining Duke Matthew. Thalwyn’s men, Luthor and Kestrel, were siphoning off the Eastern Province’s iron and smuggling it out of human territory to the Elves. The Elves, acting as the geopolitical middlemen, were then using that very same iron—along with their magnesite—to supply the Dwarven war machine.

Earl Thalwyn was getting filthy rich off the smuggled iron, while intentionally starving the Duke’s military of the resources they needed to defend the border. The Earl was letting the Dwarves slaughter the Duke’s men just to weaken his political rival.

“Lord Takuya?” the auditor asked nervously. “What do we do?”

Takuya slowly stood up, a dark, terrifyingly cold expression settling over his face. He had come here to build a hospital and a school. But to protect this village, he was going to have to destroy a Noble House.

“Compile every piece of evidence,” Takuya commanded quietly. “Copy the ledgers. Map the exact route of the missing forty tons. I want the financial noose tied so tight around Baron Luthor and Viscount Kestrel’s necks that they hang themselves before the Duke even draws his sword.”
