Datang: Destroy Tang Taizong Li Xiao at the beginning

"Shut up!"

Tie Kui sneered coldly, frowned and said, "To be able to design such an astonishing tempering technique, Qiongzhou must have a master forging master."

"Yeah, such a miraculous beating method can be designed, and the person behind it must be extraordinary."

"Master Iron is right. Does that master still have a way to further purify this fine iron?"

"This... is this unlikely? If it is possible, it would be amazing."

"Thinking too much, if every piece of pig iron can be refined to such a degree, then it's still worth it? Doesn't that mean that all the magical weapons in this world are made by Qiongzhou?"

"Quiet!"

Seeing that these people were about to start discussing again, Master Gu scolded impatiently, and then ordered: "Go ahead!"

Then, after everyone waited for a while, the piece of iron burned red again, and the second round of beating began.

Repeat this until the third round.

With a hammer down, I saw a crack in the iron block.

"Oops!"

Tie Kui rolled his eyes, and his face immediately sank.

"Bastard!"

"I just said don't continue, why don't you wait to listen?"

"Such a good piece of iron has been ruined like this, alas..."

Tie Kui looked regretful.

"It's so sad to live in your own world!"

Master Gu sighed, and then said: "Don't worry, iron smelting has just begun! This is just the most basic process."

The most basic process?

Tie Kui was dumbfounded when he heard this.

Isn't this the whole process of refining?

The next step is to cast the model, hammer it into the shape of the weapon, then fine-tune it, and finally strike.

A peerless magic weapon is done!

But now someone actually told him that this was just the beginning.

How does this make him believe?

"Forget it, today I will show you how to make steel in Qiongzhou!" Master Gu said with a smile.

"Steelmaking? What is steel?"

Tie Kui was stunned.

Master Gu thought for a while, then suddenly asked: "Let me ask you, you call it fine iron, what is its nature?"

"Refined iron is already the king of iron. Among millions of catties of pig iron, it is rare to come across such a piece. It is very rare. If it is made into a weapon, its strength and sharpness are enough to be called a magic weapon." Tie Kui frowned. Said with a frown.

"But if I tell you, its hardness, flexibility and other properties can be increased several times?"

Speaking of this, the corners of Master Gu's mouth curled up, with a playful expression on his face.

"It's impossible! Absolutely impossible!"

Tie Kui sneered and said, "Could it be that Master Gu is trying to amuse me? It's fine to lie to children with such nonsense, but we are all experienced blacksmiths who have been working as blacksmiths for more than ten years or even decades."

"Okay, then wait and see."

Master Gu chuckled, and ordered: "Cool it down and bring it to the next boiler."

After a while, everyone brought this piece of refined iron to a strangely shaped boiler.

"What is this?"

Everyone is confused.

"This thing is a converter." Master Gu said.

"Converter?" Tie Kui was confused.

"Keep quiet if you don't understand, and watch carefully."

Master Gu glanced at Tie Kui, and then gave orders.

Under the orders of Master Gu, a blacksmith from Qiongzhou came to operate it.

Throw the iron block into the high-temperature converter, then turn on the mechanism, and the steam will drive the gears.

At this time, the iron block has been turned into molten iron, and the molten iron is continuously stirred in the converter. After being filled with oxygen, it is oxidized at high temperature to remove impurities and increase the temperature in the furnace.

Then, the molten iron was poured out and mixed with Li Xiao's special molten iron purification agent.

Purifiers are used to remove impurities and further enhance purity.

This operation made everyone dumbfounded.

"This... this... the iron produced in this way can still be used?"

Tie Kui and the others were stunned.

Chapter 364: Who is the frog in the well

Tie Kui was very confused at this moment.

He couldn't figure out what the function of these processes was.

But it feels very professional when I look at it, and I always feel that doing so is a profound way of tempering.

But when he returned to reality, he recalled the skills he had learned over the past ten years of apprenticeship, and felt that the operations in front of him were outrageous.

Although he was puzzled, at this juncture, he was too embarrassed to speak out, so as not to disturb the Qiongzhou blacksmith who was working.

Subsequently, the purified molten iron goes through a series of complicated processes such as "pumping", "stirring" and "heating".

Even the boilers have been replaced several times.

Finally, molten iron has been called molten iron and should be called molten steel.

Under the command of Master Gu, the molten steel was poured into the mold, and a bright "steel ingot" appeared.

"Mysterious iron!!!"

Looking at the steel ingot in front of him, Tie Kui couldn't help shouting.

A group of Leizhou blacksmiths beside them also widened their eyes in shock, looking at the scene in front of them in disbelief.

"This turned out to be the legendary black iron!"

"Absolutely not wrong! It's as black as carbon, smooth as a mirror, but faintly red, this is definitely black iron!"

"My God! A piece of black iron was born right under my nose, I..."

"Didn't you say that black iron is a natural treasure? Could it be possible to forcefully upgrade a piece of pig iron into black iron with human power? This... this is incredible!"

"It is said that if the black iron is cast into a weapon, it will be cut like mud after the attack. The top ancient weapons in the world are all made of black iron. Over the past thousand years, only a few have been produced, and now , I actually saw Xuan Tie with my own eyes!"

"The most precious treasure in the world! Looking at the entire Tang Dynasty, it is rare to find one or two. This one must cost at least twenty catties!"

The Leizhou blacksmith who was watching was trembling with excitement.

Tie Kui was also extremely excited at this time.

Suddenly, he seemed to have thought of something, his pupils narrowed suddenly, he stared at Master Gu and asked: "Tell me quickly! You have spent a huge price to temper such a piece of black iron, and then It can't be copied either, can it?"

"It turns out that this is called Xuan Tie in your place. Is it necessary to be so excited?"

Master Gu said with a look of disgust: "How can there be only one piece? What can this piece of steel ingot do? Not even a fraction is enough to make a cannon."

Hearing this, Tie Kui stiffened all over, and said in a daze, "That is to say, you can easily make such black iron?"

Master Gu nodded and said, "Yes, what's the problem?"

"hiss……"

Hearing Master Gu's affirmation, there was a series of breath-taking voices at the scene.

After a long time, Tie Kui calmed down, and asked with twitching corners of his mouth, "Do you know what this means?"

"represents what?"

Tie Kui took a deep breath, and said in a deep voice, "In this world, there are only a handful of ancient magic weapons."

"But now, with your tempering method, it means that the divine weapon is no longer a divine weapon, and it is no longer a rare existence. Everyone can use the divine weapon."

"My Great Tang, every soldier's combat power will be increased by more than ten times because of this, and everyone is an existence with one as ten!"

After a pause, he continued: "Even, the magical effect of black iron is not only that."

"It is conceivable that in the future world, farmers will no longer be troubled by logging, and hunters will no longer need to worry that their sharp arrows will not be able to penetrate the defenses of ferocious beasts..."

"The shields and armors of our Great Tang soldiers will be indestructible, and the enemy will no longer be able to penetrate the defense, endangering the lives of the Great Tang soldiers."

"From ancient times to the present, there has never been such a craft."

"This is Pangu who opened the sky, the beginning of heaven and earth, and the source of all things!"

"It will create a whole new era!"

After saying those words, Tie Kui was so excited that he couldn't be more excited, and his eyes were even more captivating.

Beside, those Leizhou blacksmiths were also shocked by Tie Kui's words.

Thinking about it carefully, it seems that it really is the same thing.

If black iron is no longer a rare thing, what will this world be like?

It’s amazing!

can not imagine!

Listening to Tie Kui's words, Master Gu couldn't help curling his lips, and said with a look of disdain: "It's just a piece of steel ingot. Look at what you said. If I tell you, this is only the minimum standard for steelmaking here. What should you think?"

"what?!"

Tie Kui and the others were shocked again.

"Minimum Standards?"

"That is to say, can you still refine a higher-level existence than black iron?"

"how can that be?"

"Yes, how can there be more advanced mineral materials than black iron in this world?"

Leizhou blacksmith heard Master Gu's words and felt that he was going crazy.

This amazing news, one after another, makes people breathless.

"This kind of steel ingot is just the most basic thing. Its hardness is enough, but its flexibility is very poor."

Master Gu shook his head lightly, and continued: "We still have to go through some processes such as carbonization to combine rigidity and flexibility. In addition to retaining hardness, the flexibility is greatly enhanced, so that it can be used to forge weapons."

"Carbonation?"

Everyone was stunned.

"what is that?"

Although I don't understand it, it always sounds very powerful and advanced.

At this time, they no longer questioned Master Gu.

The appearance of Xuan Tie shocked them too much.

"You guys don't understand what I said, but besides carbonization, many different types of 'alloy steel' can also be produced."

"Depending on the application, it can be unilaterally strengthened for one performance direction."

"Alloy steel?"

Listening to one unfamiliar vocabulary after another, Tie Kui only felt that the knowledge he had acquired for decades was not enough.

What the hell is this?
