'Wuhua Zhai' was not too big in this city, but Xie Ling and Shen Conghu were attracted by the black iron ore piled up outside.

The first thing Xie Ling did when he arrived at Cangyue Sect was to smash ore in the gravel yard, and the first thing he chose was black iron ore, plus the 'Black Water Heavy Sword' behind him was based on refined iron, so he was very interested in it.

The refined iron refined from black iron ore is the main material of most magic weapons, the same refined iron is also very different because of the quality and refining techniques of the ore, and it is generally divided into three grades: upper, middle and lower, Xie Ling's 'Black Water Heavy Sword' The refined iron used is more miscellaneous, which he extracted from those broken magic weapons, so the quality is not good, if it is not added to the star iron and river beads, at most it can only be refined into a low-level small Zhou Tian magic weapon.

When you enter the 'Wuhua Zhai', you will see that the inside is larger than expected, with two sets of counters on one side displaying the finished materials that have been refined, and the other half of the space is divided into piles, all of which are raw ore of uneven size.

It is impossible for any raw ore to produce only one type of ore, and so is the black iron vein of Heiling Mountain. In addition to the yellow and white things in the secular world, there are also some common or rare ores in the Xiuzhen world, such as bronze ore, heptel gold ore, mica stone, and so on.

Xie Ling walked to the edge of a pile of black iron ore, and casually picked up a fist-sized piece of raw ore with his hand, with his current understanding of black iron ore, this piece of black iron ore in his hand should belong to the better quality. The amount of iron produced is large, the impurities are less, and as long as the technique is used correctly, the quality of refined iron is definitely medium and high-grade.

Shen Conghu was in front of a group of counters on the other side at this time. His gaze was drawn to a piece of golden material the size of a broad bean. I saw that the label in front of it was marked with the words 'semi-intermediate copper'.

The guy behind the counter had already paid attention to him, and said with a smile: "Guest, please see, this is a fine 'half-dimensional copper', and there is absolutely no problem with refining fire attribute magic weapons!" he said and took it out and handed it over.

Shen Conghu took it carefully, didn't speak, looked at it carefully for a long time, and then shook his head and handed it over again: "Is there a two-dimensional copper?"

"The guest laughed, the two yuan copper is the entire Xuanwu Realm will not exceed one or two, how can I have this small shop, if you have one or two dollars, it's just 6161616161" The guy looked up and down Shen Conghu smiled and stopped talking.

"It's just a 61616161," Shen Conghu said hurriedly.

"It's just that the cost is quite expensive, you need a thousand spirit stones per money, how much do you want for the guests?" said the man.

"I want a thousand spirit stones per penny!" Shen Conghu's tongue was a little knotted, he had only accumulated more than eight hundred spirit stones over the years, and his eyes fell on the half-dimensional copper of broad beans on the counter again.

The quality of Yuan copper is based on the unit, and the best known is two-dimensional copper, and then one is the second, and the value is much lower than the above two.

"This 'half-intermediate copper' is actually enough for the guests, and the Huoyun Elder of the Qingling Sect has to purchase a batch of refining weapons in this store every month, and the quality is absolutely guaranteed!"

"Then how to sell this 'semi-intermediate copper'?" Shen Conghu felt a slight balance in his heart when he heard this, so he said.

"There are only a hundred spirit stones per penny, and a few dollars added to the fire attribute magic weapon can definitely add three points of power out of thin air!" the guy said.

Shen Conghu knew that the guy didn't say a big thing, no matter how much the half-intermediate copper was, it was also yuan copper, and its effect was still not to be underestimated!

At this moment, Xie Ling walked over, and Shen Conghu said, "Senior Brother Xie, what do you think of this 'Half Jie Yuan Copper'?"

Xie Ling picked it up and looked at it carefully, because this was the first time he compared the real thing, so he was extremely serious. He turned to look at the sunlight shining in outside the door and said, "Can you try it?"

"Guests please feel free. ”

At this time, an old man in sackcloth wearing a square hat walked on, and after he finished speaking, he waved his hand at the guy and said, "You go and do the rest, I will greet these two guests." ”

The guy bowed away very respectfully, obviously the old man in sackcloth had a very high status here.

Yuan copper can absorb the essence of the sun, and the faster the better. Of course, there are other criteria, but the easiest thing is to measure the speed!

Xie Ling put it on the palm of his hand, allowing the sunlight to fully shine on it, in order to speed up, he urged the spiritual power in his body, and the yuan copper on the palm of his hand emitted a red halo, and after a while, a trace of reddish flames appeared above and below his body.

"Well, this 'half-intermediate copper' is okay, Senior Brother Shen can consider it if the price is right!" Xie Ling handed it back to Shen Conghudao.

"Even Senior Brother Xie said yes, then it shouldn't be wrong, this has three dollars, right?"

"Three coins and three cents 616161" said the old man in Mai.

"How about three hundred spirit stones?" Shen Conghu said.

"The original price is three hundred and thirty spirit stones, and the guest is coming to the shop for the first time, so he should make a friend, okay, it's three hundred!" said the old man in Mai with a smile.

After completing the transaction, Shen Conghu's wish this time was finally fulfilled, and he turned back to Xie Ling and said, "Senior Brother Xie doesn't have something he likes?"

"Don't worry, we still have to stay here for a few days, by the way, shopkeeper, I saw someone selling a small black stone outside, and the flame can't melt it, so what kind of material is it?" Xie Ling smiled and looked at the old man in Mai.

"What's the matter, the guest was also interviewed outside just now?" said the old man Mai.

"I tried 61616161 it just now," Shen Conghu said with a smile.

"You've been fooled, that thing is called 'one-yuan heavy iron', and like refined iron, it is obtained from black iron ore. But one is artificially refined, and the other is congenital!" said the old man Mai.

"Why haven't we ever heard of this?" Shen Conghu wondered.

"This is material that has just appeared, and you certainly haven't heard of it. Mai said the old man.

"The materials that just appeared?" Xie Ling was also a little puzzled.

"Yes, this is a long story, if you two don't dislike it, how about you go in and try the new tea that has just arrived at our store?"

"I don't dare to ask for it!" Xie Ling said.

There is a wing room behind the shop, which is very elegant and quiet, the old man in Mai has the surname Duanmu, the name is Lei, he is a monk with the thirteenth floor of the famous Qi training period, and has been operating the shop pù for more than 30 years, and his son Duanmu Xiuming is a monk in the early stage of building the foundation of Qinglingmen, and his shop is not big, but he can always get good goods.

Both sides briefly introduced, Duanmu Lei saw that the two were disciples of the Seven Great Immortal Sects, so he was more polite, and returned to the previous topic after being polite.
