Wizard: I have ten trillion nanomachines

To this day, Lokunlun has been on the continent of Volo for nearly four years.

The physical fitness score is fixed at 30 points, reaching the ultimate limit of the current physical body.

His own strength had already reached its peak, and no matter how much he cultivated, it would be difficult to improve.

To further enhance our strength, we must start with our weapons.

With his current physical strength, ordinary armor would only hinder his speed and agility, making it a complete burden, so it is not considered.

However, a suitable divine weapon can enhance his power, allowing him to unleash destructive power far exceeding his own limits.

Luo Kunlun had initially considered heavy weapons similar to Li Yuanba's pair of golden hammers.

With his physical strength of 30 points, even if he swings his arms haphazardly, he can still create a landslide or earthquake.

But then I thought about it again, and the heavy hammer is too narrowly applicable to different scenarios, far less suitable for various battle situations than swords, spears and lances.

More importantly, his trump card, the Resonance Slash, relies on the weapon to transmit vibration. The heavy hammer has an irregular shape, and the vibration is easily diffused, making it impossible to accurately transmit the force.

The ideal weapon must be slender and have a uniform cross-section, with a length much greater than its diameter, in order to allow vibrations to be smoothly transmitted along the axis.

Spears and clubs are included in this category, while broadswords and spears are the best choices.

It is said that Zhang Sanjia, the top martial arts scholar in the late Qing Dynasty, wielded a 180-pound broadsword during the imperial examination. His swordplay was as fierce as thunder, and he was ultimately selected as the top martial arts scholar.

Those heavy weapons specifically designed for strength training were exactly what he wanted.

However, problems arise as well. These specially made weapons are mostly cast as a single piece, with the blade and handle being one piece. They are also long and cannot be disassembled, making them extremely inconvenient to carry and even more difficult to carry out covert operations.

After much deliberation, Luo Kunlun decided to forge a two-handed greatsword.

Using the broken steel greatsword fragments from when he slew Graxis as a base, another treasured item was incorporated.

A black box containing nanomachine injections stored in the brain during time travel.

After obtaining the nanomachine, Lokunlun kept the empty syringe and the nanomachine in the space.

Apart from that one time when I tried to collect the giant bear's blood to see if there would be any new changes in the space, I have never taken it out.

The box was made of an unknown material, seemingly some kind of super-tough alloy, and its entire body gleamed with a cold, dark light.

Now is the time to put it to good use.

It was around November at this time, and there were still nearly four months before Golden Manor opened.

..............

The sulfurous, cold wind, carrying snowflakes, lashed against the mottled wooden windows of the royal workshops, making a crackling sound.

Inside the best workshop in the capital, Luo Kunlun held two oddly shaped alloy pieces in his palms. They were no bigger than a fist, yet they were heavy and exuded an indescribable sense of weight.

In this medieval-like world where even steam engines don't exist, forging an ultra-tough alloy into a divine weapon is nothing short of a fantasy.

The old craftsman Kyle, with his white hair and beard, tapped the dilapidated iron-smelting furnace beside him. Plaster and ash fell from the furnace walls. His face was full of difficulty. "Mr. Luo, it's not that I, old Kyle, am unwilling to try, but this furnace burns charcoal. The highest temperature it can get is a thousand degrees. Even refined iron needs to be forged a hundred times to take shape."

"But this 'black stone' of yours, oh dear, even if you throw it into a fire, it won't even get a red flame. How are you going to forge a sword from it?"

Luo Kunlun did not refute, but simply took out a sketch from his bag, which depicted an oval furnace, symmetrical vents, and a complex blower device. The lines were precise and the details were meticulous.

"Modify the furnace according to this plan: make the furnace hearth an oval shape that is four meters long and two and a half meters wide; ram the furnace walls with a mixture of quartz sand and refractory mortar; and then open four symmetrical tuyeres."

"We don't use charcoal as fuel, we use coke."

"Coke? What's that?"

For the next two weeks, the workshop became the liveliest place in the capital.

Luo Kunlun personally led a team into the mountains to mine coal, and later dug three dry distillation kilns in the mountain valley.

The circular earthen kiln has a ventilation opening at the bottom, and coal and firewood are laid in layers, with the top sealed with mud.

First, light the firewood, then adjust the fire intensity by controlling the size of the ventilation openings, allowing the coal to heat up slowly in an oxygen-deficient environment for several days to more than ten days. After cooling, it can be dug up to obtain coke.

When this coke burned in the furnace, the flames were blue-white, the heat was 30% greater than that of charcoal, and it did not produce choking soot, leaving the old craftsmen, including Kyle, dumbfounded.

The furnace renovation was an even more massive undertaking.

They felled ten century-old oak trees to make a support structure and used horse-drawn carts to transport whole blocks of limestone to reinforce the furnace base.

Luo Kunlun, referencing the design of the ancient Xing blast furnace, guided craftsmen to build a six-meter-high furnace chamber. Ceramic temperature measuring tubes were embedded in the furnace walls, and the interior was filled with dry wood ash for insulation.

The blower system is based on the principle of a watermill, drawing water from a nearby stream to drive a huge waterwheel, and then sending a strong airflow into the vent through a tough leather hose. The wind speed can be precisely adjusted by turning the valve.

This kind of metallurgical workshop was the pinnacle of what was possible under ancient conditions.

If it weren't for the vast amount of knowledge stored in the nanomachines, even with the technology of this world and without considering extraordinary factors, it might not have been possible to create one even after a hundred years.

Such an investment naturally came at a huge cost, but King Atlas III not only had no complaints, but also gave his full support.

He wasn't stupid. Luo Kunlun's only request was to spend money. For a powerful person like him, simply spending money to keep him in check was definitely a win-win situation.

Moreover, this workshop is truly the "cornerstone of the nation" for the Bauhinia Kingdom.

Militarily, with higher-temperature furnaces and tougher metals, soldiers and knights will have superior equipment comparable to the heavy armor of the powerful southern kingdom of Honeysuckle.

In agriculture, sturdy iron plows can deeply till the land, and sharp iron sickles can improve harvesting efficiency, thus increasing grain yield.

In trade, high-quality ironware and metal tools will become scarce commodities, monopolizing the metal trade in surrounding areas in exchange for strategic resources such as gold, grain, and minerals.

Such benefits would be enough to make all the nobles submit, and Atlas III was naturally pleased with it.

Inside the workshop at this moment.

"There's one last step," Luo Kunlun said, pointing to the newly crafted giant crucible.

This crucible is made of kaolin mixed with metal ore powder and fired; its walls are five centimeters thick.

He used his spatial ability to cut the alloy into walnut-sized pieces, carefully polished off the surface oxide layer, and stacked them alternately with wrought iron forged into thin sheets, sprinkling graphite powder on each layer to prevent oxidation and deterioration at high temperatures.

On the day the furnace was opened, the entire workshop was enveloped in a sweltering heat.

The coke burned fiercely in the furnace, making a "whooshing" sound. The water-powered blower ran continuously, and a strong airflow was injected into the furnace, making the flames even more intense.

The ash inside the ceramic tube gradually turned grayish-white, which meant that the furnace temperature had exceeded 1,200 degrees Celsius, far exceeding the limit of ordinary blacksmith furnaces.

Old Kyle personally pushed the crucible into the center of the furnace, while his apprentice Adrian stood by the observation port, watching the changes inside the crucible closely through the inlaid quartz disc.

Two hours later, the alloy and wrought iron in the crucible completely melted into a golden-red liquid, with a layer of gray impurities floating on the surface.

This material has high strength per unit weight, but fortunately it is not very durable.

"Take it out of the furnace!" Old Kyle shouted, and four burly blacksmiths pulled the iron chain together, slowly lifting the scalding hot crucible out of the furnace and pouring it down onto the pre-made clay mold.

The pottery mold was made according to Luo Kunlun's requirements. It was a two-handed greatsword, 175 centimeters long and 25 centimeters wide. The hilt had anti-slip grooves where the rope was wrapped.

When the sword blank was half solidified, Luo Kunlun personally took to the field, wielding a heavy hammer weighing a thousand pounds, and smashed it down hard on the sword blank.

Relying on nanomachines for scanning and recording, his blacksmithing skills are no less than those of old Kyle.

The deafening hammering sounds rose and fell, each strike squeezing out air bubbles and impurities from the molten metal, making the sword's structure increasingly dense.

The sword blank gradually takes shape under the hammer. Every ten forgings, it is sent back into the furnace for tempering. This process is repeated more than a thousand times until the metal texture of the sword becomes as delicate as silk, with a restrained luster.

The quenching process is particularly critical.

Instead of using the usual cold water quenching method, Luo Kunlun found a natural hot spring in advance and used ceramic pipes to channel the water to the workshop, maintaining a constant temperature of around 50 degrees Celsius.

When the sword blank is heated to 600 degrees Celsius and its surface turns dark red, he personally steps forward, holds the hilt with both hands, and slowly immerses the sword blank into the hot spring pool.

"Sizzle—!" A plume of white mist shot into the sky, filling the entire workshop; the sword was complete.

Finally, there is the sharpening and polishing.

The craftsmen collected natural whetstones from deep in the mountains and polished the swords step by step, from coarse to fine. Then they carefully wiped the sword blades with a mixture of wood ash and animal fat to remove any remaining oxide layer.

Several days later, a peerless divine weapon finally appeared in the world. The sword was as black as ink, with faint dark red patterns showing through, like the pulsation of blood vessels.

Under the sunlight, the sword's surface is as smooth as a mirror, clearly reflecting a person's image.

Luo Kunlun reached out and grasped the sword hilt.

The sword weighs exactly 200 jin (100 kg), with a balanced center of gravity, making it perfect for Luo Kunlun to swing with one hand, as if it were an integral part of his arm.

With a casual wave of his hand, the greatsword, accompanied by a whistling sound, slashed towards the anvil beside him.

when!

With a crisp, loud crack, the anvil was split in two, the cut smooth and clean, while the sword remained undamaged, its edge still as sharp as ever, without even a scratch.

Old Kyle trembled as he stroked the sword, his eyes filled with shock, his voice choked with emotion: "Sir, this divine weapon is nothing compared to the legendary Dragon Slayer Sword!"

"How about we call it 'Dragon-Slaying Greatsword'?"

Huh? The Dragon Slayer Greatsword?

Upon hearing this, Luo Kunlun shook his head: "Forget it, after all, I'm not Guts."

"It's better to keep things simple."

Although old Kyle didn't know who Guts was, he thought about it again and said, "Let's call him Mo Yuan."

The ink corresponds to the deep black color of the sword blade, conveying a sense of profundity, simplicity, and power, which fits the appearance without being ostentatious.

"Very well, let him be called Mo Yuan. Those who die by my sword should not cry foul!"

Luo Kunlun gripped the greatsword, exerted a slight force, and the vibration traveled along the blade, producing a soft hum.

He could clearly feel that the sword was almost perfectly suited to his Resonance Slash, and the vibrational force could be transmitted to the blade edge.

This is due to the vein-like patterns.

With this divine weapon in hand, coupled with his strong physique and thirty points of physical strength, he was ready to fight.

I'm giving it my all; I don't know if I can compete with the advanced apprentices.

After all this is done, there is only one and a half months left before the Golden Manor opens.

It's time to set off.
