Master descends to earth

Chapter 41 The brightest star in the night sky

The stall owner looked at Su Yuan who was in his early twenties in disbelief, and was woken up by Xu Kui's slap, and quickly introduced: "Yes, the iron ore just mined from Laoxi Water Mine is most suitable for Caogang."

Su Yuan walked up to several large sacks, and grabbed a handful of iron sand with his hands. In the traditional steelmaking method, there is a kind of steel frying method. First, iron sand is used to make pig iron, and then the pig iron is melted. During the process, it is constantly stirred. Decarburization of pig iron can turn it into iron or steel according to the degree of decarburization.

Grass steel is obtained in this way by using the local iron sand unique to Longquan. Because of the homophony of "fried" and "grass", and the appearance of the refined steel is rough and rough, it is called "grass steel" in Longquan dialect. It is one of the best materials for swords. .

Shaking his head, the quality is still not good, not even yellow light, how can it be used to make a golden lightsaber!

Huimei Liusheng watched Su Yuan's every move. For swordsmiths, iron ore selection is the first step in the Long March, and it is also the most critical process.Experts judge the quality and density of ore through years of experience, which can be said to be one in a million.

The steel of the katana sword is called jade steel, and it is also smelted using traditional low-temperature methods.Fold and forge the red-hot steel. If you fold and forge two pieces of red-hot steel 10 times, you will get 1024 layers of steel.

By folding and forging, impurities and excess carbon in the steel can be removed, thereby increasing the elasticity and toughness of the steel.The more times of forging, the more uniform the carbon content of the blade, and the finer the iron crystals will be. Finally, the forged blade will have thousands of layers, which makes the sword have strong toughness.

Su Yuan looked over it and found that there was not even a piece of yellow iron ore. He shook his head and led everyone to continue searching.Suddenly remembering something, he turned around and asked Emi Yagyu: "I heard that in Shimane, the southwest of your country, called the hometown of the gods, rare ores for special steel are produced?"

"Are you talking about the minerals of the gods?" Yagyu Huimei said respectfully: "The iron sand produced locally has the highest iron content, and there are very few sulfur and phosphorus impurities, which can ensure that the smelted steel and iron will not be contaminated by impurities. Destruction, rare, only the top swordsmiths are worthy of it."

Su Yuan curled his lips, everything is a treasure in the eyes of a little devil. After all, there are many people and few lands, and resources are scarce. I have the opportunity to see the so-called ore of God with my own eyes.

When he came to another booth, Xu Kui grabbed a handful of iron sand, weighed it with his hands a few times, and showed it: "According to my experience, a good top handle is heavy and shiny, indicating high iron content. A big bag can Picking out five or six catties is considered lucky."

Su Yuan walked to the sack and looked at the iron sand flickering with faint light. Most of them were white light. The difference was nothing more than brightness, which was basically unusable.

Scrolling down, I finally found two pieces of iron sand emitting yellow light. The weight was indeed slightly heavier than ordinary ones, and they were more lustrous. Xu Kui's experience was more pertinent.

After a few visits, I have figured out the basics of the Five Elements Technique. The white light iron ore can only be used to make a white light sword, and the better quality yellow light ore has a chance to make a yellow light sword. Unfortunately, the quantity is too small, one in a million.

Su Yuan frowned. It seems that the efficiency of traditional iron sand is too low. Even a sack can't pick out a few usable materials. The next step is to make a golden lightsaber. It's useless to buy this kind of garbage.

"If the master is not satisfied, there is ore ahead, which is dug directly from the mountain. Let's go and have a look?"

Su Yuan nodded and followed Xu Kui to continue walking inside. Many people moved large and small ores from the trucks, and many of the surfaces were covered with mud, so they couldn't see clearly inside.

Seeing this scene, Su Yuan was a little excited. This is also a different kind of stone betting, but the betting is not jade, but iron, which is a bit interesting.

The market is very lively, and many people are whispering around the ore. A piece of high-quality iron ore is very expensive in Longquan, and the supply is even in short supply. Therefore, some people get rich by gambling on iron ore, and they are playing with their eyesight.

Su Yuan looked at Xu Kui and Liu Shenghuimei's eager expressions, and ordered: "You don't have to follow me, you go around by yourself, and meet here in an hour."

Xu Kui nodded and left. He was very familiar with this place. It was rare that Su Yuan wanted to forge swords. It was the best time to learn. He quickly got a few good mines out and saw the master's true strength as soon as possible.

Huimei Liusheng was also very excited. She came all the way to Longquan to find clues. Seeing the two leave, Su Yuan found it more convenient to act alone, so he quickly started looking for the Jinguang Mine.

"I can't do this..."

"Hey, it's still yellow light, it's worse!"

"Boss, is there anything better?"

Time was running out, Su Yuan quickly shuttled among the crowd, and he could tell the general good and bad at a glance. After running down a dozen stalls, he only found two pieces of iron ore flashing yellow light.

"Huh? This is..."

Just when he was immediately disappointed, Su Yuan's eyes suddenly lit up, and he hurried to an inconspicuous stall in the corner. It was getting late, and the business was probably not very good, and the stall owner was already preparing to close the stall.

"how much is this?"

Su Yuan picked up a strange thing the size of a washbasin. It was covered with a brown shell, which was not too heavy. There were many round pits and grooves of different shapes on it, which looked very ugly.

The stall owner took a look at it and introduced it while cleaning it up: "This thing is something I picked up from the abandoned mine in Laoxi. The texture is not very good. Take it away for two thousand!"

Su Yuan suppressed the joy in his heart, frowned on purpose, pretended to study for a long time, seemingly unintentionally asked: "Laoxi abandoned mine? I often go there too, why haven't I seen such a strange thing?"

"It's right next to the grove south of Calabash Ridge. Don't tell me, I rarely see this kind of thing. I definitely can't make a sword, but it's quite interesting to collect."

When Su Yuan got the information he wanted, he paid the money and left without saying a word. He left the distance and couldn't help but excitedly said: "Hahaha, God help me, this is really God help me!"

"You can actually meet a meteorite!"

Meteorites are cosmic meteors outside the earth that have deviated from their original orbit, or unburned stone, iron or stone-iron mixed materials that are rapidly scattered on the surface of the earth or other planets.

More than 4 meteorite samples have been collected all over the world in various styles, which can be roughly divided into three categories: stony meteorites, whose main component is silicate; iron meteorites and stone-iron meteorites, a mixture of iron and silicates.

The piece in front of you is an iron meteorite, containing 90% iron and 8% nickel.The surface is covered with a black or brown oxide layer, called a fusion crust.

Large and small round craters are called gas prints, and grooves of various shapes are called melting channels. These are all formed due to their violent friction and combustion with the atmosphere during their fall.

In Su Yuan's eyes, this meteorite shone with rich golden light, yes, the golden light shone like gold.

"This yellow mud..."

Su Yuan pinched the dirt attached to it with his hands, and it actually shone with the same golden light. Could it be that...
