Novel legend of northern blade chapter 16

<-- Episode 16-->

Jinmuwon also held a hammer today.

Land land!

Every time he hammered, sparks splattered in all directions, and the heated iron began to find its shape little by little.

In the intense heat, sweat was flowing from Jinmuwon's whole body like rain. In the middle of winter, it was just as bearable, but as spring came and the energy came, it was hard to bear. Still, Jinmuwon silently hammered without saying that it was difficult.

The work of hitting a hot iron ball with a hammer is called forging. As the impurities inside the iron are discharged to the outside through the forging operation, it has a tighter and denser structure.

For forging, pine charcoal powder and straw-burned powder are used as carburizing agents. Apply finely ground powder to the surface, heat it up in a furnace, and when cooling off, knead the powder of loess, white clay, and rice straw in water and sprinkle it on the iron.

After completing the series of work, the iron is heated again in a furnace and hammered. When the impurities inside are discharged to some extent by hammering, cut the center of the iron with an ax and fold it. And the sequence of hammering again is called folding.

In the Cheon Byeongjinseo, it was written to repeat forging and folding at least twelve times to make a proper weapon. If you repeat forging and folding twelve times, you will have a structure in which four thousand ninety-six layers of thin iron plates are stacked with iron, which was just a lump.

By repeating the forging and folding of twelve times, all impurities are removed, and the weight of the iron is also reduced to a fifth. Only then is the preparation to make a single sword.

From this point on, I had to lengthen the iron to get the shape of the sword. Put the iron in the furnace, heat it evenly, and hammer it.

Shit!

Each time Jinmuwon hammered, the red-hot iron gradually took on the shape of a sword. Jinmuwon's hammering hand was unstoppable. Sparks splattered in all directions, and his face and skin were ripened by the hot heat, but he never stopped working.

Tsutsu!

From some point, a white haze was rising from Jinmuwon's body. I don't know when, but while working on making a sword, Jin Muwon naturally began to operate Man Young-gyeol. Fighting and neutralizing the heat of the furnace, the shadow internally grew naturally.

While hammering, Jin Muwon was learning to use the beats and shadows that could naturally produce optimal power.

The iron that used to be tacky now has the shape of a perfect sword. But the work wasn't over. More important work remained.

Jinmuwon put the sword back into the furnace. At this time, it was important to adjust the furnace temperature. The knife that was put in the lowered furnace was naturally cooled at room temperature three times.

This is called an annealing operation, and it stabilizes the internal structure affected by the impact due to the forging and folding work, and the crystal structure is evenly aligned.

“Whew!”

Jinmuwon sighed as he looked at the sword he had made through several days of hard work.

Now, the most important work remains to be quenched and sharpened.

Jinmuwon applied the pre-prepared mud to a difficult sword. A thin layer of mud was applied to the blade, and a thick layer was applied to the blade to dry the whole day.

Jinmuwon put a sword with dry mud in the furnace. As time passed for a candle to burn, the blade heated up to a clear red color. Jinmuwon did not miss this moment and took out his sword and put it in the water he had prepared in advance.

Chi profit!

In an instant, the water heated up and steam rose. Then Jinmuwon quickly pulled the sword out of the water.

The blade part coated with mud quickly cooled and became very hard, while the part of the blade that was applied thickly cooled slowly and slightly softened.

This differential heat treatment prevents the blade from exiting by dispersing the impact received from the blade as much as possible.

Jinmuwon closed his eyes and waited for the sword to cool while operating Man Younggyeol.

The shadow naegong that had settled in his belly wriggled, and soon began to flow through his body with his blood chart. It's because it was difficult to make at first, but once it was formed, the shadow naegong was growing at a terrifying rate.

The shadow naegong had a secret yet somber nature. Like wet cotton, it gradually soaks into other energy and transforms it into the same shape as itself.

From the other side's point of view, it is pollution, and from this side, it can be seen as absorption. Even now, Jinmuwon's shadow naegong was digging into the absorbed heat and making it the same as himself.

Thanks to that, Jinmuwon's strength was increasing at a terrifying rate. Yet, externally, there was no mark at all. No matter how much martial arts are at the extreme, you will never be able to know that you have mastered the internal skills only by looking at Jin Mu-won's external appearance.

After finishing Daejucheon, Jinmuwon opened his eyes. In an instant, the intense eye light exploded, then gradually disappeared, regaining the original normal look.

Jinmuwon got up from his seat and lifted a completely cold sword. There were still a few more work left, such as setting the blade, but it could be said that it was almost finished.

Jinmuwon removed the mud still attached to the sword. Then, a smooth, silver-colored sword appeared. The body shining in silver like a beautiful woman's naked body was shining dazzlingly without any fine scratches.

Jin Moo-won flicked his sword with his finger while appreciating his work for a while.

Taang!

The sound of clear metal rang in the room, but Jinmuwon's expression was not so bright. Jinmuwon, who bounced a few more times, became darker.

“Whew!”

With a sigh, Jinmuwon suddenly lifted his index finger and pointed at a part of the sword he had completed.

Shhh!

Instantly, with a sharp metal sound, the sword exploded in all directions. Jin Muwon looked at the scattering pieces of iron with a bitter face.

“Are you a real fan again?”

On the outside, it was incredibly perfect, but it was a failure. In Jinmuwon's eyes, there was a flaw hidden behind perfection. It's a very subtle flaw that can be ignored, but Jinmuwon couldn't even tolerate him.

While dealing with iron and fire directly to make a sword, Jinmuwon saw the grain of iron. Iron with perfect texture was beautiful and perfect, but the iron that was not contained contained imperfections, such as a brick-and-mortar, which you never know when it will explode.

If you impact the texture with the correct force at the right moment, it will break like this. That was the reason Jinmuwon was able to break the sword so easily.

In response to a small enlightenment acquired by accident, Jinmuwon named it "Swaebyeongji (碎兵指)."

Even though he got a crushed bag, Jinmuwon's face didn't open at all. Because what he wanted was to understand the sword perfectly, not to learn a cryptic gimmick.

Jinmuwon collected sword pieces, put them in the furnace, and came out. After returning to his residence, Jin Muwon suddenly realized that he couldn't see an esoteric theory. There was no trace of holding a spoon on the food I had made in advance to eat while I wasn't confident.

“There’s no way he could have eaten with his own hands, so he must have starved.”

Jinmuwon shook his head.

As I looked at my face every day, I now know all the little habits of Eun Han-seol. She never cooks and eats with her own hands. Not only was he not interested in making food, he wasn't talented.

She pursued practicality to the point that she considered spending time on work without talent or talent as a waste of her life. Probably, while Jinmuwon was trying to make a sword, she was starving and engrossed in martial arts.

“Not a kid… … .”

Jinmuwon shook his head and opened the warehouse door on one side of the residence. The food warehouse was full thanks to Hwang-cheol's visit not long ago. Jin Muwon took out some ingredients from the warehouse and cooked food.

After making rice, side dishes and Japanese sweets, Jin Muwon came out. It was to sing Eunhanseol.

Jinmuwon crossed the Yeonmujang and headed for Eunhanseol's residence. It wasn't that difficult to find Eunhanseol. This is because Eunhanseol was standing on the roof above the hall.

“What are you doing there?”

Jin Muwon called, but Eun Han-seol was looking only at the south without answering.

“What are you seeing like that?”

Jinmuwon whine and climbed onto the roof. Still, Eunhanseol had no answer. Jin Muwon looked in the direction she was looking at.

“What the hell… … .”

Jinmuwon shuts his mouth.

A dust breeze from the south came and a group of wagons escorted was running towards this place.

"Well!"

Jinmuwon's face hardened unavoidably.
