Martial: I Started The Technological Revolution In Ancient Times

The heat wave surged out and burned a few strands of his hair.    

However, he was not afraid. He said with surprise, "The temperature is up!"    

However, Badao's face was full of doubt. He asked, "Young master, what is the reason for this?"    

Xiao Yun explained, "You are also a person who practices martial arts? Why are you so slow to sense the surrounding environment? Previously, when you pulled this bellows and used all your strength, it would take you at least an hour to sweat. After another hour, your back would get wet, but now, it's only been a short while. You're sweating? First, you don't have a cold, and second, you don't go out at night to be cool. Of course, it wasn't because of the weakness in your body. It could only be because the furnace temperature rose. When the heat waves are released, your body can feel the heat! "    

Badao was stunned for a moment and then immediately said, "Yes, it is indeed much hotter than usual!"    

"Continue, add carbon drum wind! Looks like that stone can be refined today!"    

The most primitive smelting was actually quite simple.    

In nature, metal was embedded in the rock in the form of particles. It could be considered a physical fusion, not a chemical fusion, and thus became other matter.    

If it was a chemical fusion, in order to extract the metal, some chemical reactions were needed. This was not something Xiao Yun could do at the moment.    

However, it was still possible to extract those particles.    

There were many components in the stone, but most of them were objects with extremely high melting points. They could not be melted easily.    

The metal had melted more than a thousand degrees, and the rock was still intact. Therefore, the metal flowed out of the rock in liquid form. When it gathered together, it would be an impure piece of metal.    

In fact, it was that simple.    

The so-called smelting technique was only to control the temperature. For example, when melting copper, the temperature would be slightly uniform, and other metals would not melt as well. The copper would also flow out together, and this kind of copper would be slightly purer.    

Only slightly.    

There were many melting points like copper, and gold was one of them. Thus, when copper was refined, it was usually made of alloy.    

If one were to look at it from a different perspective, it was likely that the matter of 'gold and copper does not separate' also existed in nature in the form of accompanying ores because the melting points of gold and copper were similar!    

Of course, this was just gossip.    

The key was that the black metal that Xiao Yun had obtained from the blacksmith shop could already be considered a complete piece of metal. Star Iron. This name that sounded somewhat cute was indeed something beyond the heavens!    

As long as it was smelted a little, there was no need to refine it. It would be good as long as it could be dissolved and easily molded.    

This actually involved the difference between forging and smelting.    

One had a high level of skill, while the other had a high level of skill.    

There was no distinction between superior and inferior.    

The content of the design was a little complicated.    

Xiao Yun originally thought that he did not need to consider this.    

He just needed to use the smelting method.    

But...    

Things went against his wishes!    

He needed to make two pieces of metal.    

One was Star Iron, and the other was Soft Gold.    

They were both objects from beyond the heavens.    

The reason why the temperature of the furnace had to reach 1,890 degrees was because the melting point of the soft metal was the same as the melting point of the Chromatic Metal.    

As expected, when the soft gold entered the furnace, a golden metal solution flowed out from the stone very quickly. It looked as if it had a life of its own as it trembled and flowed. Finally, it gathered in the crucible, as if it could pulsate with gold. It was very likable.    

After burning some of the impurities, especially some of the impurities, the melting point was very low, causing their boiling point and vaporization point to be very low as well. Thus, like water vapor, they were all burned away!    

After waiting for a while, Xiao Yun took out the crucible and poured it into a groove that had long been prepared. He then began to mold it. After that, he also had to do some grinding, quenching, and other procedures.    

This was to be done after that.    

What was more important now was to smelt the Star Iron as well.    

But... when the thing went in, it would only turn red and soft. If he wanted to melt it, he would always be one step away!    

Xiao Yun couldn't help but sigh.    

This was the best furnace in Great Qin Country. After his own modifications, it had already reached the pinnacle of technology in this world.    

But... it still couldn't do it.    

However, it could be considered a blessing in misfortune. There was no chance for smelting, so there was a chance for forging!    

Yes, the method of smelting was very simple. The purified metal could be placed in the groove and directly molded.    

However, if the melting point was not reached, then there was no way to completely melt it. That was, there was no way to increase the furnace's temperature. What should he do?    

Furthermore, even if he reached the melting point, he would not have the corresponding ability to remove impurities...    

Even in Xiao Yun's previous life, he could only refine steel a few decades ago.    

This was very difficult! Extremely difficult!    

It was not something that could be done with just a slap to the forehead.    

However, before that, what could people do if they wanted high-performance steel? Forging!    

Using their craftsmanship to make up for their lack of skill.    

Just like what a general did, when he did not have the technology and did not have a grasp of coal and other new energy sources, he could only use extremely complicated craftsmanship to improve as much as possible.    

Forging meant that the item had not been melted, and the shape could not be molded. What if he wanted to remove the impurities? He would smash it! What if he wanted to mold it? Smash!    

With all kinds of hammering, Xiao Yun could be said to have used all his strength. From day to night, and from night to day, the soft metal was made of metal. The hard metal was like debris that splashed with impurities.    

After a while, at midnight on the third day, when it was time to rest, the metal finally stopped changing.    

It was burning red, like a piece of hot tofu.    

A metal ingot weighing dozens of kilograms was smashed into ten kilograms!    

And because the density of this object was too high, the remaining materials were only the size of a fist.    

Xiao Yun's eyes turned. He stopped eating and sleeping. He forged it overnight and forcefully forged it into the shape of a crescent moon.    

This was called a crescent moon blade. It was curved and had a single blade on it.    

The crescent moon blade of others was about three feet long, but this one of his was less than a foot long. It looked more like an exquisite piece of art.    

The others had blades on the inside, and they used them like sickles. The cutting effect was excellent.    

However, Xiao Yun had blades on the outside.    

When he cut something, he would use force to walk out. If an ordinary person used it, it would hurt the skin and not the bones.    

The biggest difference was that when the Star Iron first appeared, it was completely black.    

At this moment, it was as white as silver!    

That kind of white, the white was fresh and translucent, and the white was as white as snow!    

Even Xiao Yun himself had a look of shock on his face.    

He couldn't understand why the original black metal had turned white after being forged. This reversal was a bit too big.    

However, Xiao Yun didn't think too much about it. He picked it up and wanted to sharpen the edge of the blade. However, when he grinded it, he discovered that only stone powder was left on the grinding stone, but not the flesh on the knife!    

If it did not drop, how could it be sharp?    

He tried several types of grindstones, but he could not grind it off. In the end, he even used a diamond. In the end, the diamond did not move, and it did not move either!    

This didn't mean that its hardness was at the level of a diamond. It was just that the toughness of this thing was too high, and its wear resistance was too good.    

Helplessly rolling his eyes, he could only burn and smash again. Using his own technique, he forcefully knocked out a blade angle!    

Then, he did not even need to quench it and directly cooled it down.    

On the other side, the soft gold also cooled down. He returned to the furnace to withdraw the fire, and knocked on the molding model. Carefully, Xiao Yun used a small hammer to crazily hammer, and the short palm-sized knife forcefully knocked hundreds of thousands of times!    

Knocking it into a perfect mirror was one thing.    

When he looked back, he saw that the two knives had already been formed!    

One was as bright as a crescent moon, and the other was like the golden light of the morning sun.    

The Sun and Moon Dual Blades had been formed at this point.    

It was even better than what Xiao Yun had expected.    

Clapping the two blades between his fingers, Xiao Yun laughed out loud in satisfaction.    

Badao could finally rest.    

He had been crazily pulling the bellows for the past few days. He felt that his arms were no longer his. His upper half of his body was numb!    

However, he also came over curiously and asked in a low voice, "Young master, this knife of yours is pretty and heavy, but it doesn't have a handle. How do I use it? If the hidden weapon is a little bigger..."    

Xiao Yun smiled and said, "Handle? It is in my hand. As long as the blade is in my hand, it will be fine."    

"This... can be used?"    

Xiao Yun laughed. He shook his hand and a white light flashed. The moonblade flew past and stabbed into the anvil beside him. The tip of the blade cut into three parts of the metal!    

Badao's eyes widened.    

If he wanted to do this, he could do it too, but he needed a good knife. He needed to accumulate strength and cut it hard.    

Xiao Yun's actions were too casual.    

That was why it seemed a little scary.
