one's door

Chapter 227 Lian Xi
The blacksmith shop that Zhang Yan was looking for was the largest one in Langyuan City. It is said that there are also many branches in Nanyuan Kingdom, operating a series of goods channels from raw materials to finished products.It was also Zhang Yan who came to the door after he asked Zhou Cang to find out.

With Zhou Cang's introduction, and Zhang Yan's current status as a guest teacher in the martial arts academy, the shopkeeper of the blacksmith shop dare not be perfunctory.After reporting the news, look for it in shops and mines in various places.Due to time constraints, there are only more than ten kinds that have been gathered together and handed to Zhang Yan.There are basically some ores that have something to do with "special".Some can be used, and some are regarded as waste in the shop.I don't know if these can satisfy Zhang Yan.

But this teacher Zhang's shot is really generous.Just looking for it paid a lot.The shopkeeper thought so in his heart.

And Zhang Yan's expression remained the same, but he listened very carefully, followed the shopkeeper's same introduction, and picked up the same induction and discrimination.

Although he is not yet a craftsman, Zhang Yan's understanding during this period of time also allowed Zhang Yan to enter the door with half a foot. He is not a layman who knows nothing.According to the vast number of material properties recorded in the ancient books of refining equipment, it is a simple comparison.It's not difficult, but it's a little troublesome.

"This kind of... um... brittle iron stone is interesting, do you usually encounter many?"

After the shopkeeper finished the introduction, he heard Zhang Yan pick up a black stone in the box and asked a question with a smile, and quickly replied with a smile: "Many! This brittle iron stone is often accompanied by iron ore, and there is almost no difference in shape, so it is often misunderstood. Fortunately, I can still find it when I sieve it before putting it into the furnace. If I am careless, mixing this thing in can waste a whole furnace of ore. It is extremely annoying. Moreover, this thing can only produce brittle iron when it is smelted alone. It’s useless. But it’s definitely in line with the special word I taught you.”

It is indeed very special, it looks like iron ore, and it can be smelted in the way of iron smelting, but it is so brittle that it will shatter when touched.It's not that people in Huangtianyu haven't thought about this thing, but they can't find any use for it.So this thing is a very special but very useless typical.In terms of time, the shopkeeper also used it to make up the numbers. After all, if there are too few samples, it is not easy to explain to Zhang Yan.

"It's really special." Zhang Yan smiled, feeling pleasantly surprised.Because he found a corresponding material in his mind that was recorded in the classics of refining equipment, which was an extremely high-quality material in the era of earth legends: iron crystal.

There is only one word difference between iron crystal and iron essence, but they are two completely different things.Like gold essence, iron essence is a common main material for refining equipment that is extracted from iron by means of refining. The grade is not high, and it is mostly used to cast low-level magic weapon bodies.But Tie Jing is far more precious than Tie Jing even though it is just one letter away.

It is a great waste even to smelt iron crystals by the method of iron smelting, because it is only a half-smelted semi-finished product.So the finished product made in that way is not crisp enough!It requires a special refining method to maximize its "brittle" characteristics, and the obtained iron crystals are the purest.

Why does it need to be "crisp"?
Because for some things, the more brittle, the harder it is!Its brittleness is just because the hardness has reached a certain extreme, and it lacks toughness, so it cannot maintain the overall structure when resisting impact.And iron crystal has very stubborn independent characteristics, it is extremely difficult to be compatible and complementary with other things, so it is regarded as "waste".

Even though it is called "iron crystal", it actually has nothing to do with metal.It just looks like it.

Of course, since iron crystal can be called "extreme material" in the classics of refining equipment, there must be corresponding refining techniques to tame it.

One thing you can't tolerate, you're independent, right?Then add a few more, first refine a special material suitable for iron crystals, and then add iron crystals into it.In that case, the super hardness of iron crystal can find complementary toughness.This is also the best refining method for weapon-like magic weapons that pursue hardness and toughness.

"If I want to collect a large amount of this brittle iron stone, how can I sell it?"

"A large amount? Dare I ask how much is the teacher going to accept? If it is a few dozen catties or a hundred catties, I can decide to give it to him. If it is more, then we have to look at it in detail." The shopkeeper is also not around the corner.Although he didn't know what Zhang Yan could do with this thing.But it did not prevent him from giving a clear answer immediately.

Things are worthless, if they are a hundred catties, they are just a gift.But if it requires a lot, labor costs will be unavoidable, and there may be some business that can be done inside.After all, businessmen.When it is said to be waste, it is "waste" because it cannot be sold for money. When it can be sold for money, it is no longer "waste".

In fact, it can be seen that the number of iron crystals in the barren sky domain is far greater than that of the earth.It can even be said to be extremely unusual here.God knows how many there are in the entire Huangtian Territory?
But a hundred catties of iron crystal ore?How many iron crystals can be practiced?And this is not a one-off deal, there will be demand for a long time in the future.

Moreover, it is impossible for Zhang Yan to open a blast furnace and revolve around the iron crystal ore all day long.

"It's not just one or two hundred catties of ore, but a hundred catties of brittle iron that may need to be smelted in a blast furnace at one time. And I will ask for it from time to time. You can ask your number to keep it for me, and just refine it for me when I need it. Calculate the fee according to your account, and you can’t let your account lose money.”

"Ah? The brittle iron produced by smelting? It costs more than a hundred catties at a time?! Teacher, you may not know that one catty of brittle iron costs hundreds of catties of brittle iron ore. This hundred catties of brittle iron. Are you really Are you kidding me?"

Although there are a lot of brittle iron ore, they are only associated ore types after all. There is no way to dig one basket after another after a set of mine tunnels are drilled. They can only be picked out at the end of the ore dressing.It is not easy to collect a hundred catties.It is so troublesome to smelt one catty of brittle iron, but this teacher Zhang opened his mouth to say a hundred catties of brittle iron.Are you sure this isn't a joke?
Zhang Yan didn't talk nonsense, and nodded directly, expressing that he was serious.

"This..." The shopkeeper thought about it, and quickly got a set of business rules in his mind, and then followed Zhang Yan with a smile and talked about the scarcity of brittle iron ore, and how brittle iron would damage the blast furnace.Finally, when he took out the price tag in his heart, he found that Zhang Yan didn't even pay the price at all, only to realize that he seemed to be timid.

After agreeing to deliver a batch of ten catties of brittle iron in three days, Zhang Yan paid the reward for the previous mine search, and at the same time gave the deposit for the first batch of brittle iron, then left the blacksmith shop and went to a not too far away. Great jewelry store.

Zhang Yan collected the gold nuggets here before.Later, I asked the other party to find some strange stones.

It was similar to the situation at the blacksmith shop before.Naturally, all kinds of beautiful stones are the most contacted in jewelry shops.The more beautiful the stone, the more "gem" it is, and the more expensive it is.

It was also in these bright stones that Zhang Yan found another unexpected surprise: Lingshi.
