After the auction, Hua Yan had been holding back his breath in his heart, he had a big military training, and after only a month, he was countered by the Light and Dark Alliance and the Star Moon God Cult, and he blatantly threatened and persecuted the Steel City.

Especially the Light and Darkness Alliance, he actually directly injured Shi Feng with a weapon, and every time he thought of this, his anger kept going up, but he also knew in his heart that now was not the time to be angry, so that day in the auction hall, he forcibly suppressed his anger and did not make a move.

He wants to improve his strength as soon as possible, and he also wants to help the Steel City improve its strength, the sense of urgency in his heart makes him dare not waste a trace of time, now that the materials for building weapons are complete, the most important thing at the moment is to forge a sword.

Hua Yan first sorted out some images of ancient Chinese swordsmiths, trying to learn some experience from them, although Hua Yan has basically figured it out in theory, but when it comes to the real sword casting, the experience of many ancestors is still very important.

The same is to cast a sword, Hua Yan is currently preparing to do something is still obviously different from the ancient Chinese people, because of the limitations of science and technology, the ancient Chinese people have no way to refine rare metals, mainly using bronze and chromium alloys, and Hua Yan's iridium platinum chromium rhenium alloy at auction is much more complex than bronze.

Of course, the various property indicators of iridium-platinum-chromium-rhenium alloy are also much higher than those of bronze, and Hua Yan also has a lot of expectations for the sword he wants to cast.

Hua Yan packed up the iridium-platinum-chromium-rhenium alloy and the golden Buddha that had been warmed and cultivated into soul gold, and came to the city within a city on the surface of the Steel City.

As soon as he entered the blacksmith shop, the bald boss with a tattoo of a mountain tiger on his chest greeted him and said with a flattering smile:

"Director Hua, come here, the small shop is really shining."

"Oh? Do you recognize me? ”

Hua Yan was a little surprised.

"Director Hua moved the city bricks with his bare hands, and also organized a large-scale military training in the city, no one knows in this steel city, that one doesn't know, now everyone in this steel city knows that you are the second in command in this city in addition to the city lord!"

The bald blacksmith shop owner spat and splashed stars, and praised Hua Yan for a while.

Hua Yan was also a little embarrassed to be touted, smiled awkwardly, and said:

"What's the boss's surname?"

"Don't have your surname Shi, a single word is fierce, called Shi Meng."

The bald boss replied busily.

"Shi Meng? Are you also from the Shijia Martial Arts Pavilion? ”

Hua Yan asked with some confusion.

"No, no, no...", the bald boss waved his hand again and again, and then said:

"I'm no longer from the Shijia Martial Arts Pavilion, I used to be in the Shijia Martial Arts Pavilion, but my qualifications were too low, and I didn't build runes, so I was sent out, and I also learned some blacksmithing skills in the Shijia Martial Arts Pavilion, so I came out and opened this blacksmith shop."

"Oh~"

Hua Yan nodded, and then asked:

"Boss Shi, I want to borrow your blacksmith shop today to build a weapon for myself, I don't know how much it costs?"

"What did Director Hua say, you want to use my blacksmith shop to make weapons, that is the blessing of my blacksmith shop, then what money is needed?"

Although Shi Meng looks very strong and rough, he is also a very sophisticated person, and he slapped Hua Yan with a lot of sycophants.

"You're welcome, Boss Shi, it's not so easy for me to build this weapon, it is estimated that it will take several days, and I may need your help, in addition, do you have a furnace here that can reach a high temperature of 3500 °C?"

As Hua Yan spoke, he took out two giant desolate fruits and stuffed them into Shi Meng's hands.

When Shi Meng heard Hua Yan say this, his expression was also much more solemn, he took the two giant desolate fruits, and said after a while:

"Director Hua, if it was before, there was really no furnace with such a high temperature, but in the past half a year or so, more and more people have come to smelt some demon beast materials, and some of these materials require extremely high temperatures, so I used more than a dozen high-pressure acetylene oxygen welding guns to transform a furnace, which can reach nearly 4000 °C, but I don't know if it is suitable or not?"

"Oh?"

Hua Yan glanced at Shi Meng with a little surprise, but he didn't expect that this tattooed bald man was still an active-minded craftsman.

"Okay, Boss Shi is extraordinary, then let's try it first!"

Hua Yan gave Shi Meng a thumbs up and said with a smile.

Then Hua Yan took out the iridium-platinum-chromium-rhenium alloy and the warm-raised golden Buddha, and Shi Meng also began to arrange for the furnace to be fired, and sent the two apprentices home first.

Then the door of Shi Meng's blacksmith shop was closed, and only Hua Yan and Shi Meng were left inside, and they began to forge swords!

The piece of iridium, platinum, chromium, rhenium, which weighed more than fifty kilograms, was controlled by Hua Yan with soul energy and sent into the furnace, and then more than a dozen blue-purple high-pressure acetylene oxygen flames began to spray at the piece of material.

At a high temperature of nearly 4000°C, the iridium-platinum-chromium-rhenium alloy alloy began to melt slowly. Now Hua Yan's soul energy strength is more than 500 kilograms, which is much greater than the power of the iron hammer, so now he simply gave up using the hammer and directly used the soul energy to control the melted alloy to start slowly forming, which can also minimize the probability of impurities mixed in the alloy.

Seeing that this furnace could be used, Hua Yan's heart was also shocked, but he thought of another problem, he needed to smelt for a long time, and he was afraid that the fuel in this furnace might not be enough, so he asked:

"Boss Shi, how long does your furnace's fuel last?"

"It can last for more than two hours!"

Shi Meng replied.

More than two hours is definitely not enough, you have to hurry up and prepare fuel, thinking of this, Hua Yan quickly used the brain network to contact Hong Zhan and asked him to arrange to send some fuel over.

A few seconds later, Hua Yan turned his head to Shi Meng and said:

"You go to the Hunters' Guild Hall now, find Hong Zhan, and prepare enough fuel for me for five days in a row."

"Yes! Director Hua. ”

Shi Meng agreed, and hurried out of the blacksmith shop.

More than an hour later, more than 50 kilograms of iridium-platinum-chromium-rhenium alloy in the furnace had all been melted, and at this time, Shi Meng had already returned to prepare the fuel.

It's just that the alloys of these four metals are a little bit of a sign of wanting to separate after melting, which makes Hua Yan a little unexpected, and remembers what Zhou Fangzhi once said to him, should this alloy material be smelted badly, once separated, the property parameters of this material will drop a lot, and even become a scrap.

But it's already at this point, so I can only bite the bullet.

"Melt up the golden Buddha and take a third of it and send it to the furnace."

Hua Yan frowned slightly and shouted to Shi Meng.

"Yes!"

Shi Meng didn't dare to slack off, and quickly melted the golden Buddha with another stove, and then took about one-third of the golden juice and sent it into the furnace.

After the golden juice entered the furnace, it began to turn into golden silk threads under the control of Hua Yan's soul energy, and entered the liquid iridium-platinum-chromium-rhenium alloy alloy that had melted.

Hua Yan is going to construct a "Kun" character text first, and after the rune is constructed, see if the running rune can prevent the disintegration of this alloy material.

Using soul gold to construct runes in metal, this is the first time Hua Yan has done it, although there are some video materials of ancient Huaxia swordsmiths, and there are references to other ancient swords, but this step is still very difficult for Hua Yan, and it is much slower than building it in his own brain.

It took a whole day and a night, the "Kun" character text was finally constructed, Hua Yan breathed a long sigh of relief, the operation of the "Kun" character text, does not need soul energy, only needs three strands of material energy, 4000 °C high temperature, after dozens of times of Hua Yan's debugging, this "Kun" character text can finally run successfully.

After successfully running the first "Kun" character text, Hua Yan was pleasantly surprised to find that the trend of separation and disintegration of these four metals stopped!

It seems that he made the right bet, Hua Yan was secretly happy.

With the operation of the runes, the combination of iridium, platinum, chromium, and rhenium became closer and closer, and the attribute indicators were also rising, and finally after more than 20 operations, they began to stabilize, and Hua Yan also stopped.

Under the control of soul energy, this pool of liquid alloy also began to slowly condense into the shape of a sword, but now it is still a sword blank, and Hua Yan is still preparing to experiment with the next idea.

He was going to construct another "wind" character script in the sword blank.

This is something that has not been done before, the ancient Huaxia people used the ancient sword mainly to store soul energy, and then used to build runes in the body, and Hua Yan because he has a divine palace, he does not need this storage function, he now has enough soul energy available, he plans to try it, and then build a "wind" character text in the sword, to see if there will be other unexpected effects.

Now that the soul gold in the furnace has only been used up a small half, Hua Yan has not stopped, and dozens of gold wires have begun to enter the sword blank, and the construction of the "wind" character script requires two strands of soul energy and one material energy, and three strands of energy are input by Hua Yan into the gold filaments composed of these soul gold, and begin to run and debug little by little.

This time, it took longer to construct the rune than the "Kun" character text, nearly two days and two nights, and finally the "wind" character text was successfully debugged, and with the operation of the "wind" character text, the sword blank began to appear bursts of "hum... Hum...", and formed a series of sword aura brilliance around the sword.

And a layer of fine spirit patterns began to appear on the sword body, and there seemed to be a smart luster flowing.

Hua Yan was overjoyed, it seems that this "wind" character is really useful when integrated into the sword, and the effect is surprisingly good!

In the following time, Hua Yan began to use soul energy to decorate the subtleties of the sword blank, and the hilt, swallow, and blade began to take shape one by one, and after half a day of meticulous carving, the sword finally took shape.

More than fifty kilograms of iridium-platinum-chromium-rhenium alloy were not wasted at all, and a small part of the soul gold remained, the whole sword was one hundred and eighty centimeters long, fifteen centimeters wide, the sword spine was three centimeters thick, and the hilt was twenty-five centimeters long.

"Flameout!"

Hua Yan said softly.

"Yes!"

Shi Meng, who was standing aside and accompanying Hua Yan, who had also been unsightly for several days and nights, hurriedly turned off the furnace.
