"In addition, this, this, these three minerals, I also need to refine and purify, as for what ingredients are in it, I'm sorry, I can't tell you, this is a secret technique given to me by the master, and no one can mention it, second brother, you are no exception. ”

"In the end, the main forging work is still done by you, I am responsible for controlling the fusion of various metal materials with my divine sense, forging and quenching and cooling need to be completed by you, and polishing and grinding also need to be completed by you. The ancient craftsman Ou Yezi created three divine swords, Longyuan, Tai'a, and Gongbu, but it was not completed overnight, are you mentally prepared?"

The Longyuan Sword is the Longquan Sword, because it needs to avoid the name of the Tang Dynasty Emperor Li Yuan, it has been renamed the Longquan Sword since the Tang Dynasty, but in the Zhongyuan world, it is still called the Longyuan Sword.

After Yue Heng finished speaking, he quietly waited for Lei Fat Man and Yue Feiyan, and found that the two of them were stunned, staring at Yue Heng in surprise, their eyes full of disbelief.

"Third brother, you ...... Did the master really teach you the secret art of sword forging?"

Lei Fatzi didn't believe it at all, Shao Li taught Yue Heng the tricks, formation spells, and even poems and songs, he would not doubt these at all.

But if it is said that Shao Li knows how to forge swords, he has never seen Shao Li use weapons in the Misty Valley, and he has not seen the existence of swords and spears everywhere, how can a literati know how to forge swords? Even Guiguzi himself does not know how to forge!

Yue Heng blinked: "If it weren't for the sword-forging technique that my master taught me, do you think I learned it by reading books myself?"

"This ...... It seems that it is also oh, I learned to cast weapons, and it took me seven years to lay the foundation, and I can have a little bit of understanding, you are a literati ......" Lei Fat Man shook his head, don't say it, as long as Yue Heng can be round, it doesn't matter where he learned it!

Yue Feiyan asked a little excitedly, "Gongzi Yue, are you saying that you can use the power of the runes and your divine sense to control the forging process, and it is possible to fight a divine sword like Longyuan Tai Agongbu?"

Yue Heng nodded: "Miss Yue, don't be too excited, it's up to people." I've never forged a sword, but don't you two masters help me, I just need to control the composition of the sword embryo according to the secret technique of sword casting. Don't talk about it yet, hurry up. Let's start with the extraction of trace elements. ”

In the first smelting, Yue Heng and Lei Fatzi did their work, Yue Feiyan supervised and commanded on the side, Yue Heng chose the manganese element, which can mainly increase the hardness of steel. If it is a divine weapon such as forging a Longquan sword, it only needs a little bit as an additive.

Yue Feiyan motioned to Lei Fatzi to load some manganese-containing ore with a connecting rod trailer and prepare to send it to the smelting furnace, Yue Heng stopped him and said, "Now it's just for experimentation, it doesn't need to be too much, Miss Yue, all the minerals are reduced, if necessary, I will use my divine sense to control it." ”

He set up a circle of spirit gathering. Using the beast soul to provide energy, Yue Heng controlled his divine sense as much as possible to contact these minerals, and the purification began.

Yue Feiyan adopts the secret technique of Yue craftsmen, and in Yue Heng's view, it is actually a high-temperature manganese aluminum replacement method.

The manganese ore is smelted with a ground fire higher than 1000 degrees, and the manganese oxide is decomposed into manganese tetroxide, and then replaced with aluminum ore to obtain pure manganese metal, which is the most effective smelting method that Zhongyuan World can explore.

Consciousness is essentially an energy that burns at temperatures as high as 1,000 degrees Celsius. Therefore, Yue Heng couldn't use too much manganese ore for experiments, from the beginning of feeding to smelting into molten metal, Yue Heng's divine sense was almost half consumed, if it weren't for the help of the Spirit Gathering Array. It may hurt the vitality.

Yue Heng was pleasantly surprised to find that with the help of the power of the "Ye" rune, his divine sense could keenly separate the required elemental molecules and remove more impurities.

For example, manganese tetroxide is a relatively stable component of manganese ore, and although his divine sense cannot directly purify manganese from the atomic level, it can isolate other substances that do not contain manganese. In this way, he can obtain more than 99.99% high-purity manganese tetroxide, and then react with high-purity aluminum to replace the manganese element.

Half an hour later, seeing the steaming high-purity manganese metal on the shelf in front of him, which was about the size of half a football, Yue Heng sighed with emotion.

Just such a gadget, it cost him about four pieces of fifth-level beast soul energy, not to mention that the main ingredient of the sword embryo requires more iron, no wonder the craftsman is called a money-burning profession.

"This piece of metal is so beautiful, is it of high purity?" asked Fat Ray.

Yue Heng nodded and glanced at Yue Feiyan: "In Miss Yue's words, this should be hard and fine iron." ”

He couldn't say the manganese element, so he could only call it ferromanganese according to Yue Feiyan's statement, Yue Feiyan sighed and said: "Gongzi Yue, it seems that you have found a blank field that literati have never had, and you have become a friend of craftsmen......"

Yue Heng smiled: "Miss Yue, don't say that, you can't do more of this kind of thing, you don't know how much I have lost, I have already hurt my soul." ”

Lei Fat Man didn't know if what Yue Heng said was true or not, he was quite concerned about him, only to see Yue Heng continue to take out the beast soul energy, and said, "Let's continue!"

The next metal is nickel-iron alloy, and Yue Heng consciously can't do it to purify nickel metal alone, so he just physically purifies the "polished mythril gold" white copper introduced by Yue Feiyan, removes some impurities, and the rest is nickel-iron alloy.

The divine consciousness consumed by pure physical purification was not too much, and after Yue Heng got the nickel-iron alloy the size of a baby's fist, he said lightly: "Go on!"

Within two hours, Yue Feiyan felt more and more that something was wrong when she supervised the work, and she found that Yue Heng often used some uncommon and even inexplicable combinations to carry out smelting operations, some of which were even unheard of by the craftsmen of the Yue Kingdom, or considered unfeasible after thousands of experiments.

But after Yue Heng's combination and combination, some minerals that were obviously impossible to smelt together miraculously merged after a chaotic combination!

Yue Feiyan knew that Yue Heng must have used a mysterious substance similar to an "affinity", but she was very knowledgeable and experienced, but she still couldn't understand Yue Heng's dazzling combination, many of which were smelted out, and even the metal she didn't know what it was was thrown into the furnace twice, three times, to produce the fourth and fifth strange metals.

In two hours, Yue Heng had already scrapped more than thirty pieces of beast soul energy, and some of the rare minerals accumulated in Lei Fatzi's hands had also been taken out and consumed.

Could it be that Yue Heng had already prepared the materials for forging the sword, but he found that when the "Metallurgy" rune smelted minerals many times in a row, the comprehension ability would become deeper and deeper, this was very easy to understand, just like the proficiency, the more metal types he came into contact with, the more different feelings his divine sense felt, and the proficiency would naturally improve.
