Yu Ci naturally couldn't rush back now, in fact, there was no need at all.

He just said casually: "The magic weapons of the Liu family, I have also seen them, refining, refining, and making tools, they are miscellaneous, but it is a pity that there are great materials." ”

As soon as the words fell, a rough and angry voice came from his ears: "You Taoist priest, it's so unreasonable, did the surnamed Liu provoke you?"

When Yu Ci turned around, he saw a tall and powerful, almost bear-like man, but his skin was a little too fair, and his eyes were open angrily at this time, and he could see that he was very dissatisfied with Yu Ci's evaluation.

According to the intelligence, this is the refining master who is the most proficient in large-scale refining of mineral materials in Jujing Fang, Liu Shande.

Obviously, this person was hired by Sanxitang and had just rushed over to deal with the materials, but he was annoyed for a while when he heard Yu Ci's not very friendly evaluation.

Yu Ci smiled: "This is Master Liu, don't blame, don't blame." In fact, I still admire Master Liu's level of refining materials. However, I have seen a magic weapon, and although the Dark Tide Sand refining in it is good, the sacrifice is chaotic, and the magic weapon is also very average...... It's not one or two people who say that. ”

He described the sword qi gourd a little, and Liu Shande's face was still not good-looking, but his tone eased:

"Our Liu family has never sold gourd-shaped magic weapons, what you said is the 'Black Sword Gourd', only the refining is handled by the ancestors, but whether it is the sacrificial refining or the sword qi gourd as a container, it has nothing to do with our Liu family.

This is the reason why Liu Shande's father and son, in the intelligence chain, lack real value.

As first-class refiners, their father and son handle all kinds of materials every year, in millions or tens of millions of catties, all the clues are gathered in them, and then spread on a large scale.

In recent decades, more than half of the monks around the Barrage Mountains have been in contact with them through guò tools and materials.

Even Liu Shande has the ability to never forget, and he can't remember every family.

For more than ten years, the information that Yu Ci's followers have spied out has come to an end.

To be honest, it was not easy for Liu Shande to remember that sword qi gourd.

Yu Ci suspected that this was because more than one person had mentioned it to him in the past few years, either explicitly or secretly.

Sure enough, the more Liu Shande said, the more annoying he became: "The sword qi gourd is a thing about the sword Xuan system, and this was also popular back then, and there are more people who forge it near the sea and mountains, but I didn't think that the limelight has passed in the past few years, and I am looking for it." Our Liu family has just refined a batch of dark tide sand and used it on it, how the guests refine it and how it is used has nothing to do with us!"

"Success or failure. Typologies are always remembered better. ”

Yu Ci replied, and then said with a smile: "When Master Liu said this, don't you understand?

"Speaking of which, it is also fate to be able to meet a first-class refiner like Master Liu, it just so happens that I have some questions about the refining of raw materials that I need to consult, and I also want to see Master Liu's wonderful refining techniques, I wonder if I can accompany him when refining the dark tide sand for a while?"

Liu Shande really didn't have a good impression of the fake Taoist priest in front of him who was holding a stunning beauty, but it was inexplicably difficult to refuse such a "sincere" request, so he could only respond with a straight face:

"Dark tide sand is not a rare material, and the method is simple. But if the guests want to see it, it's nothing. ”

Yu Ci nodded, turned his face and asked Steward Chu again: "Of those heavenly mines, what two are missing in your hall?"

Steward Chu responded honestly: "Chenguang Stone and Star Refining Copper." ”

Yu Ci's eyebrows raised, sometimes, God likes to joke with people.

The two missing ones are exactly what Yu Ci is most familiar with and needs.

Not to mention the importance of star smelting copper, Chenguang Stone was the first batch of high-grade materials that Yu Ci came into contact with.

Back then, in the Heavenly Rift Valley, he obtained seven fragments of Chenguang Stone from the place where the demon lived, and he always suspected that it was the remains of a magic weapon, and it was owned by the powerful Taixuan Demon Mother. Later, at the mountain gate of the Lichen Sect, Uncle Rude used the seven fragments of Chenguang Stone to create a seven-star sword for him, which was of the highest grade, but unfortunately it was lost during the battle with Mr. Gaida.

Now recall the nature of Chenguang Stone, and use the legal analysis of the Nine Laws of Heaven and Man, Chenguang Stone should be one of the most suitable natural minerals for the Taixuan vein.

Yu Ci identified those ores, not just to cover for Star Copper Smelting, but also to collect some for some experimental use, but unfortunately, this idea seems to be temporarily interrupted.

Yu Ci didn't ask any more questions, but said: "As long as there is inventory, your hall's distribution speed should still be trustworthy...... So, I'll go and see Master Liu's refining techniques first, don't you mind?"

"Guest, please take care of it, when you come out, the five minerals must have been fully configured. ”

Looking at Yu Ci's rippling pupils, Steward Chu felt a little palpitating inexplicably, and unconsciously added: "We can also ask other stores to try to distribute the goods and make up for those two ores." ”

As soon as the words came out, I felt reckless. But at this time, Yu Ci had already responded with a smile:

"That's tiring. ”

After that, he signaled to Liu Shande, and he took it with him and went to Yiyin Treasury with Baoyun.

The Yiyin Reservoir is located at the edge of the forbidden area controlled by Sanxitang, and has a channel to communicate with the refining pool on the periphery of the core area, which can attract various external forces such as magma and cold springs for refining purposes.

Liu Shande's temperament is a little strange, but in essence, he is still an extremely professional refiner, and after entering the workshop specially prepared for him in the library, he bored his head and did his own thing.

Yu Ci and Baoyun didn't bother him for the time being, just watched quietly.

The two of them saw that the famous refiner had drawn a large amount of dark gray sand from the special conduit of the storehouse into the prepared empty pool, and during this time, he often stretched out his hand and secretly probed the gushing sand fountain to determine the basic nature of the gravel, and looked very cautious.

Yu Ci asked in the back: "It's all dark tide sand dug from the Qingtan of 'Jiaocheng', will there be any difference in it?"

"Jiaocheng Qingtan covers an area of 100,000 acres, and the surrounding environment is harsh, and there are often sea creatures washed ashore, and the impact of its blood on the sand and gravel is very complex, and this is only one of the reasons that affect the quality of the dark tide sand. ”

Liu Shande is used to answering questions, and while dealing with the gravel, he also knows everything.

"Just now the guest mentioned 'Tiankuang', which is also a big factor. In order to speed up the generation of the Heavenly Ore Vein, the Sects of the Barrage Sea Mountain laid a traction circle in the Biluo Heavenly Domain, which was very large, and many meteorites that should not have fallen here were also smashed down, and the density was amazing. If a meteorite hits nearby, it will also cause the sand to mutate......"

Yu Cizhen chatted with him: "So, even if the refining dark tide sand comes from the same origin, it is also different in nature, and the corresponding method of sacrifice should also be changed?"

Liu Shan responded: "Actually, large-scale refining of materials, this kind of problem is always unavoidable, it is good to deal with all defective products, and it is difficult to have a similar situation if you change the heavenly mine purchased by the guests and carefully carve it...... Hehe, everyone in this world has it, this kind of defective material, and some people are still engaged in collections. ”

The latter sentence jumped out, and it was completely true.

Liu Shande didn't notice it at all, as the dialogue between him and Yu Ci deepened, the activity of the brain palace was far more than usual, and some details that he would not have thought of were also popping out one by one, and he was open-mouthed, saying whatever he thought.

Yu Ci's voice was not in a hurry: "Engage in collections?"

"It's Yang Ming in the original mining area, his biggest preference is to collect the deteriorated parts of these materials, and there are two warehouses in his house, all of which are these things, and sometimes they are also sold out, and the price is rising like a head, profiteer!"

"It's been a habit for a long time. ”

"That is, when my father was alive, that guy had already started, and the partnership alone had been maintained for more than a hundred years. ”

"I see. ”

At this point, Yu Ci took the initiative to change the topic and began to talk about other things, and also asked some questions about refinement.

Liu Shande has a sharp hand, and his mouth is also sharp, knowing everything, and saying everything.

In this way, when this batch of dark tide sand is refined, not to mention anything else, it turns out that his mouth is dry.

At this time, Yu Ci and Baoyun had already left the workshop and returned to the store of Sanxi Hall, where they took over several materials that had been packaged from Steward Chu.

Steward Chu was also showing them his merits: "I'm ashamed, I'm ashamed, I've contacted a few shops, and I only got these six or two stars of copper smelting...... The mining of Chenguang Stone has always been controlled by the Lingchen Sect, and now they are too busy to take care of themselves and have no intention of doing business. Guests can come back after a while. But at that time, it was impossible to say whose property it was. ”

"It's okay for Steward Chu to help me keep an eye on it. ”

Yu Ci dealt with it casually, opened the encapsulated box, and saw that it had been refined into a special metal in the shape of semi-solidified droplets, and nodded slightly. Although it is a drop in the bucket, although it is a "pure goods" that has not been processed by the means of the magic gate, it can be regarded as a good start.

After putting away several heavenly mines and paying for the goods, Yu Ci asked about something again:

"I've heard that there are people in the market who specialize in collecting and selling mutant materials......

Steward Chu was slightly stunned, thought carefully for a moment, and then said: "You mean Yang Ming in the original mining area, there is this person! Hey, the Yang family's broken household has been nesting here for half their lives, studying some inexplicable things." However, the guests have a good eye, and if they are lucky, they may be able to dig up some treasures from there. ”

"The Yang family, is it the one that has something to do with the Four Ming Sect?"

"It's that Yang family, and now they can get close to the Four Ming Sect Masters. However, this family has long been a side branch, and it has nothing to do with the main family, but it is hanging in our hall......"

"Oh, you said Youngder. ”

"Ouch, you know the guest?"

Yu Ci smiled dumbly: "I know a little bit, I have dealt with it...... Sometimes it's just a coincidence. ”
