As Snow had expected, Arlene melted the pig iron with ease. Pen %Fun %Pavilion www.biquge.info Snow resisted the heat wave on the side, and kept stirring with a refractory stick. After sufficient combustion, the magazine and carbon in the pig iron are quickly removed, and the carbon content is rapidly reduced. Because Snow had never used the method of frying steel in books before, this was the first time. He couldn't grasp the essence of it, and he couldn't see the level of carbon content in the molten iron.

But fortunately, Snow's goal is clear, that is, to use the steel filling method to refine steel. In this way, it is simple, as long as the carbon content in the molten iron is removed as much as possible by sufficient stirring, then the pig iron can be converted into mature iron. After more than ten minutes of constant stirring and burning, Snow felt almost there. After Yalian stopped and waited for the molten iron to cool and solidify, Snow checked and made sure that the pig iron had been converted into wrought iron.

Now that both raw and wrought iron are available, the steel filling method can be implemented. Snow first asked Aarnium to cast a spell to melt the pig iron in a deep groove. Then, in proportion, the molten pig iron is poured onto the wrought iron that has just been smelted. Then it is repeatedly melted with a black flame, and it takes a whole hour for the raw and wrought iron to completely blend into a whole.

Because the steel filling method uses pig iron as a carburizing agent, the temperature after melting is high, which greatly accelerates the carburizing speed to wrought iron, shortens the smelting time and improves productivity. In addition, at high temperatures, the carbon, silicon, manganese, etc. in the liquid pig iron react with the oxide inclusions in the wrought iron, and the metal structure is purified at the same time, and the quality of the steel is better improved. These two points are incomparable to 100 steelmaking and frying steel.

When it was all done, Araine almost collapsed. Snow hurriedly helped her aside, and only after she had recovered did he relax.

Pulling out Yalian's dagger, Snow was full of excitement and scraped off the black substance on the surface of the iron plate in the deep groove, and the raw and wrought iron, which was originally gray, had now turned into a bright white with a flat surface.

"It worked." Snow looked at the steel in front of him and said excitedly.

Yalian on the side looked at the bright white steel in front of her, as if she thought of something. Quickly took the dagger in Snow's hand and slashed at the steel plate with all his might. I only heard the sound of ping-pong, and there was not even a trace of scratches on the steel plate.

Yalian's mouth opened wide, and she said in a daze: "This ...... This is, Kim...... Gold, iron, stone? ”

The so-called gold, iron and stone is another name for steel by those nobles. Yarlian had the privilege of seeing it once, and she was impressed by something shinier than silver coins and harder than iron.

"That's right, it's gold, iron, and stone." Snow said with a smile.

"Yes...... However, it was obviously iron just now. Yalian said suspiciously, she really couldn't figure out why Snow poured it back and forth, turning iron into gold and stone.

"This ...... It's science. Snow thought about it, but still put the reason on science, not that Snow didn't want to explain it to Yalian. It's just that the principle of this is too incredible for this era. Speaking of Yalian, not only can I not understand, but I will also have more questions, what is carbon content, what is neutralization, why is it called carburizing, and so on. These extended questions will only make Yalian more distressed.

Snow will slowly explain some scientific knowledge to Yalian and them, but only from shallow to deep, and after the stabilization of Ruke Town. Now, he really doesn't have time.

After instructing Yalian to keep quiet, the two quietly returned to town. Snow slept soundly that night, but Yalian didn't fall asleep, and she wondered what kind of expressions the townspeople would look like when they saw such a large piece of gold and iron stone in the livestock farm after dawn tomorrow.

The next morning, it was Gerosanne who first discovered that pig iron had turned into gold, iron, and stone, and as the only professional blacksmith in the town, he naturally recognized gold, iron, and stone. His father was lucky enough to hit a piece that was only half the size of a palm. Just such a small piece of money was exchanged for six gold coins, which is equivalent to the salary of an ordinary blacksmith for six or seven years. If it weren't for his grandfather following Laosk to build the statue of the god, he would have offended the church and the count. He believed that with the help of these six gold coins, the family would have a good life. Then his grandfather and father would not have died of illness, but these are only ifs.

Although the memories were not good, Gerosan knew too well the value of these gold and iron stones, which was almost equivalent to the same amount of gold. And if you polish these gold, iron and stone into weapons. It will definitely be sold for a sky-high price at the Rondell auction house, which is a huge fortune.

Gerosan's excited shouts instantly attracted the townspeople. After listening to Geralsan's explanation of being slightly crazy and dancing. Randolph and the others quickly ran to the deep groove, and took a closer look at it to determine what Geralusanne said. Everyone was stunned for a moment, followed by cheers that resounded through the sky. Except for Randolph, no one thought about why the iron, which was fresh yesterday, turned into gold and iron overnight. Everyone just cheered loudly and ran to tell each other.

"Tell the mayor the good news." Abra beckoned, and all the residents ran to Snow's room to be the first to report the good news.

"Abra, don't you think it's strange? These ores are not qualified. Logically speaking, it is already very good to be able to smelt iron, but how can it be possible to smelt gold, iron, and stone? Randolph frowned and asked, "And yesterday we all saw it really, it was indeed iron that came out of the oven, how did it change overnight?" ”

"Hey, I said Randolph, you can't even answer this question for an alchemist. Isn't it so surprising that the appearance of gold and iron stone is? Abra said disapprerovingly.

"But this time, the gold and iron stone is such a big piece, and the quality is ridiculously high." Randolph frowned, he felt that the appearance of Jin Tieshi this time must not be a coincidence.

Randolph said happily, "In short, these gold, iron and stones are placed in front of us, and we can't fake them." Suffice it to know that, regardless of how it came to be. ”

"You, it's just simple." Randolph gave Abra a blank look, "I said, if we can know how these gold and iron stones came to be, then we can refine more gold and iron stones." Think about how much wealth it would bring to our town if we could do it. ”

"You're right." Randolph's words woke up Abra, but after thinking about it, Abra shook his head again, "The reason for the appearance of Jin Tieshi can't even be understood by the alchemy master, how can we do it." ”

Randolph patted Abra and said, "Let's go and find the mayor." ”

The entire process of smelting this batch of gold, iron and stone, as well as charcoal and shaft furnaces, was all designed and directed by Snow. If the appearance of Jin Tieshi is really not accidental, then the reason for its appearance can only be explained by Snow alone.
