In his original world, Liu Yun, who had been an ordinary high school student, did not continue his studies. To be honest, he knew a lot about steel.
In the modern industry, those with less than 0.02% carbon content were called wrought iron, and those with 0.02% to 2.11% carbon content were called steel.
Iron with a carbon content of more than 2.1% was called pig iron.
Simply put, the lower the carbon content of steel, the softer the ground would be. The higher the carbon content, the more brittle and hard it would be.
Although what Liu Yun had bought previously was called pig iron, it could only be called wrought iron in modern times because it had very low carbon content and a lot of impurities.
At this moment, the pig iron kept getting thinner and smaller under Liu Yun's hands.
Liu Yun kept hitting every part of the red-hot iron block with the hammer in his hand, causing the impurities in the iron block to decrease.
Although he did not know what modern craftsmanship was like, Liu Yun was currently using the basic forging method he had obtained from the system.
Now, Liu Yun was using the Zhen Formula of the hammer technique. Through a special technique and the circulation of true energy, he could knock out the impurities in the iron block.
With a sizzling sound, the water surface instantly boiled.
When he finally placed the iron piece into the water channel at the side, a large amount of white smoke immediately appeared.
He picked up the iron block. At this moment, the iron block was much smaller and much uglier.
Although it was much uglier, Liu Yun knew that the hardness of this piece of iron had increased by a lot.
Liu Yun exhaled lightly. Although there was no time here, he felt that he had spent almost an hour dealing with this piece of pig iron.
"Looks like you have quite the perseverance!”
Liu Yun threw a piece of metal to the side. Just as he was about to reforge the next piece, the system's voice suddenly appeared in Liu Yun's mind.
Clang! Clang! Clang!
As the system's voice suddenly appeared, Liu Yun paused for a moment before continuing to hammer.
Faced with the system's praise, Liu Yun said helplessly,""It's fine if you don't work hard. Not to mention that I will become a eunuch if I don't complete the mission in a few months, if I can't find a divine technique of the same level before the Red Fire Divine Technique reaches the highest realm, I will be dead for sure. I'm not a phoenix that can be reborn from the ashes. If I die, I'll really be a dead ball. Although he wasn't sure if there was a martial art on the same level as the Red Fire Divine Art in this world, it would be too difficult to find it even if there was one. Therefore, it was better to forge a divine weapon as soon as possible and then extract martial arts.”
"I didn't expect to gain experience from forging iron blocks. Although it's a bit lacking, it's still alright.”
After forging a few pieces of pig iron, Liu Yun was surprised to see that his experience bar had increased from 0/100 to 3.5/100.
This was the eighth piece, which meant that reforging one piece gave 0.5 experience points.
He had bought 400 pieces of pig iron. After forging, he would not be able to level up by two, but it would not be a problem for him to level up by one.
Once he reached level two, he would be able to draw a prize.
Thinking of this, Liu Yun became even more motivated.
The sound of metal clashing against metal rang out throughout Sword Crafting Valley from day to night.
Liu Yun had been in Sword Crafting Valley for a week straight. If it were not for the fact that he had become more and more skilled and that the time he took to reforge the iron blocks had become shorter and shorter, a week might not even have been enough.
He returned to his room and soaked his hands in the medicine that he had prepared earlier.
Liu Yun felt the medicinal power of the potion seeping into his skin and repairing his tired hands. He immediately felt a wave of comfort.
"I say, System, you're really stingy. I'm the only one in such a big manor. Why don't you give me some maids or servants?”
"If the host is willing to use the number of times to upgrade the lottery to exchange, the system can give you ten maids and ten servants.”
"Forget it." Upon hearing the system's suggestion, Liu Yun rejected it without hesitation.
Servants and maids could be hired or even bought directly. However, although the swordsmith's level promotion lottery was not limited to this time, it was an unlimited lottery. If one was lucky, they might directly draw a divine artifact.
Moreover, it seemed that the level of the swordsmith was easy to level up at the beginning, but Liu Yun had reason to believe that it would become slower and slower in the future. After all, this was the usual routine in online games.
At the beginning, they would level up by killing a small monster, but in the end, they might not be able to level up even once in a month or two or a year.
"System, give me the lottery."
"Are you sure?"
"Of course I'm sure."
After hearing the system's question, Liu Yun replied again.
"The random upgrade draw begins. The attacking host has drawn a divine weapon blueprint.”
"Haha, I told you I was lucky. " Damn, how could it be this..." As the system's voice sounded in Liu Yun's mind, Liu Yun, whose hands were still soaked in medicine, instantly exploded with excitement.
He had been worried about the initial mission, but now he didn't have to worry at all.
However, when a piece of information suddenly surged into his mind, Liu Yun expressed that his headache was even more intense.
He had thought that he would be lucky enough to get the Divine Weapon Blueprint and be able to forge a Divine Weapon to promote the reputation of Sword Crafting Mountain Village.
The reputation of the person who forged this divine weapon was indeed enough, but the problem was that with his current strength, he was simply unable to forge this divine weapon.
Not to mention that he was now a novice swordsmith, and not to mention the difficulty of forging this divine weapon, just the metal needed for it was afraid that this world did not have it.
"System, let me ask. Is there Black Frost Iron in this world?"
"Don't worry about this, host. There's no Black Frost Iron in this world.”
Upon hearing the system's answer, Liu Yun's expression was as interesting as it could be.
Black Frost Iron, also known as Black Frost, was one of the Four Great Mystical Stones in the Wind Cloud World.
Legend has it that the so-called Four Wondrous Stones were left behind by Goddess Nüwa after she mended the heavens. They possessed four divine stones with strange abilities.
As one of the Four Wondrous Stones, Black Frost was forged into two divine weapons, the Peerless Sword and the Sword of Defeat.
Back in the Windcloud World, the ancestor of the Sword Reverence Manor wanted to use the black frost to forge a peerless divine weapon, and this divine weapon was the Sword of Defeat.
However, the Sword of Defeat's murderous aura was so strong that nine swordsmiths died on the day the sword was completed.
As a result, the Sword of Defeat that was about to be completed was sealed, and the remaining half of the Black Frost was used to forge another divine weapon that would shock the world, the Peerless Sword.
This time, the Divine Weapon blueprint that Liu Yun drew was not the Sword of Defeat, but a peerless sword.
It was just that forging a peerless sword required Hei Han. However, after asking if there was no Hei Han in this world, how could Liu Yun not feel despair?
Without Black Frost, he would not be able to forge a peerless sword. It could be said that what he had obtained was basically useless. He could not even use it to wipe his buttocks.
"System, how much would it cost to buy the black frost from you?”
Liu Yun had no choice but to ask the system.
