"So, the first step is to remove the impurities. To remove impurities, the calcination method is generally used. Depending on the material, we have to use at least two forging methods, one is extremely hot fire and the other is extremely cold
Water refining, through the cooperation of the two, achieves the purpose of refining materials."
"Your meteorite has been in the world for thousands of years and has been tempered by water pressure, so it has been tempered by water. And now I am tempering it in another way! Fire!"
With that said, Koushiro activated the flame beside the furnace mouth, and the rolling flames sealed inside surged out, but under Koushiro's control, they obediently burned towards the head-sized meteorite.
Koushiro paid close attention to the changes in the ten thousand-year-old meteorite iron, carefully controlled the flame at the furnace mouth, and adjusted the temperature of the flame and the center of gravity of the calcining.
A quarter of an hour later, two quarters of an hour later, and even an hour later, the ten thousand year meteorite iron slowly turned into a large mass of dark red liquid under the fierce flicker of the flames. Seeing this, Koushiro increased the firepower,
He also controlled the molten molten iron from a millennium meteorite, carefully dispersed it, and completely accepted the calcining of the flames of the earth fire.
Qiaoluo saw green smoke constantly coming out of the dark red liquid. This was a sign that impurities that were easily burned away were being removed, and the color of the liquid slowly became redder.
After burning like this for another quarter of an hour, the liquid completely turned red. At this time, Koushiro waved his hand again and quickly added a blood-colored crystal to the molten iron from the ten thousand year meteorite.
Then he said to Qiao Luo... "This blood crystal can be combined with some impurities in the thousand-year meteorite to precipitate, so the flame blood crystal is an indispensable material for refining the thousand-year meteorite." Koushiro reminded.
Qiao Luo quickly wrote it down. He saw that after the Flame Blood Crystal was added, it quickly turned into a ball of transparent red liquid. Then the two liquids started to bubble when they were mixed together. Not long after, a bubble appeared under the liquid.
There were white particles, Koushiro quickly took out those particles.
"The second step is to refine the blank. The blank is the foundation and skeleton of the famous sword. It is the container that carries strength and various auxiliary items. Therefore, the blank is also very important for a famous sword.
"This is called throwing sand in our forging industry." Koushiro, who was shirtless next to him, explained.
Shi said, "Use all your strength to hit the sand onto the surface of the mold, so that the sand and the mold can completely fit together."
While he was talking, Koushiro finished the work of throwing sand. He waved the shovel and quickly shoveled the sand in front of him into the iron box, tamped it down, and then added more sand.
After doing this several times, seeing that it was difficult to add any more sand to the box, he pulled out his long sword from his waist and scraped off the excess soil with one blow. Then he lifted the iron box and turned it over.
The red concentrate liquid slowly flows in along the grinding tool.
After seeing all the magma-like liquid flow into the mold, time gradually passed, and the meteorite liquid became much clearer. Then I saw Koushiro waving again, picking up a porcelain bottle next to him, and pouring out a ball of silver-white liquid.
.
"I fuse mercury and 10,000-year meteorite iron together, which can greatly improve the quality of the 10,000-year meteorite iron. This is the smelting method in the sword-making method. After the two are completely mixed, the 10,000-year meteorite iron will be
The preliminary refining is over.”
The mixture of thousands of years of cold liquid and mercury was constantly stirred and mixed under the control of Koushiro. The color became lighter and lighter, and finally turned into dark black with dots of white floating on it.
Seeing this situation, Koushiro said: "Look, now that the refining of the ten thousand-year meteorite iron is completed, I want to build it into a blank."
As soon as he finished speaking, Koushiro waved his hand, and the earth fire flames dimmed, leaving only a fist-sized stream. The dark red liquid stretched under Koushiro's control into a ball about five feet long and about five feet wide.
Three feet of thin plate.
While the thin plate had not solidified, Koushiro waved again, poured some unknown powder from the bottles and jars beside the furnace, and blended it into the liquid.
"These are all used to increase the flexibility of the sword blade. You must know that a good sword not only has an unparalleled sharp blade, but also has a soft and lingering feel around the fingers!
After saying that, Koushiro took out his handkerchief and wiped his forehead. Qiao Luo took a look and found that there were already beads of sweat on Koushiro's forehead.
"This forging consumes the most energy. Even if your body is made of iron, you can't stand it." Seeing Qiao Luo looking at him, Koushiro explained.
After saying that, Koushiro turned down the ground fire again, leaving only the liquid to solidify naturally in the air.
"Okay, now let's wait for the blank to cool down and check the quality again. As long as there is no problem, we can do the next step on it."
Koushiro took advantage of this time to rest for a while. After waiting for less than half an hour, the blank had cooled and formed. Koshiro took it in his hand, waved his hand back and forth in the air, and then nodded with satisfaction.
Koushiro threw the sword to Qiaoluo again and asked him to try it out. Qiaoluo held it in his hand and didn't feel anything different. He also tried it and found that it was indeed very different from the sword he had used before.
The big difference is that it feels like the slash is transmitted easily without any obstruction.
After feeling the blank, Qiaoluo returned the blank to Koushiro. Koshiro took it and said: "The next step is to beat it. This is also the most precise part.
"The third step is fine forging. Polish the imperfections on the blank piece by piece and smooth it out bit by bit. This is the most critical step. A swordsmith should not let his work have flaws, so
At this point, you must be fully focused.
Koushiro rolled up his sleeves and tied them tightly, tied his hair up and put it in a hat.
"You remember, forging a weapon is a physical activity. A little laziness and shaking when you need to exert your strength may lead to poor forging or even scrapping. When you are tired, go to rest nearby, but when you need to exert force, don't act like you haven't eaten.
."
However, when he saw the scene in the room again, Qiao Luo still felt that his eyes were shocked!
The huge metal block was firmly fixed on the cast iron. Around it, a hammer covered with armed domineering was beating back and forth on the piece of pig iron at high speed. The dark hammer was slowly moving under the control of Koushiro next to it.
Slowly approach the metal surface.
The moment it came into contact, the surface of the metal stirred up countless iron filings, sparks and debris. However, he showed no sign of stopping. Instead, he slowly beat away against the surface until the pig iron was gone.
At each point, Koushiro next to him breathed a sigh of relief and temporarily put the hammer aside.
Dang, Dang, Dang, Dang! The whole forging room resounded with a pleasant knocking sound...!
