(); Yu Haiyang accompanied Chang Ming around the various stores in the black market, and the more Chang Ming looked, the more surprised he became.

This market is called the Black Market, and it is located under the beneath of Qi Tian City, right under the noses of the royal family and the Royal Mechanics Association, but the scale is extremely staggering!

The first Ocean Beast Material Store he entered was indeed the largest one, and that was because the body of the Ocean Beast was already very large, and it should have such a large footprint.

But here, there is a strange beast in each booth, and it still feels a little empty.

But when he goes to other stores, especially the market for processed materials, he doesn't feel this way at all!

All kinds of materials are piled up, divided into categories, arranged one by one according to grades, and Chang Ming is stunned at a glance!

Chang Ming is not a person who has never seen a large number of materials, when he was in Heaven Slaying City, he simply made the warehouse of the War Commission his home and stayed in it for a long time. But even that warehouse, compared to this store, is like a small supermarket compared to Metro, it is not a first-level battlefield at all!

Chang Ming walked all the way and looked at it, and after the initial surprise, he gradually frowned.

Although there are a lot of these materials, they are a little different from what I imagined!

In his thoughts, most of the materials sold on the black market are materials that cannot be obtained by ordinary people, especially some high-end and rare materials, which will most be circulated at high prices in such places.

But surprisingly, there are still many low-level materials below level 5 here, and high-level materials are very rare!

Strange, there were so many high-level alien beasts in the Ocean Alien Beast Farm just now, which is equivalent to high-grade materials, why is there no such kind of material in the materials that have been processed? Could it be that they were sold out before?

Chang Ming shook his head and continued to look down.

Of course, even if it is rare, it is only relatively speaking, and it still appears much more frequently than outside. Chang Ming saw a lot of things on the list, and he couldn't buy them in Jintan City, but here, he just piled them up casually, which seemed to be inconspicuous.

Chang Ming bought it according to the name on the list, and finally stood in front of the metal material field.

The largest item on the list is metallic, called Shuiliujin, which is a fourth-grade metal material.

This metal is flexible, malleable, stable, and does not undergo oxidative changes under normal conditions. Chang Ming needed a ton of water to keep gold, and Jin Xiao bought about ten kilograms in Jintancheng, so he bought the market over there empty. Now there is still a difference of more than 900 kilograms, Chang Ming originally planned to buy it on the black market, but when he looked at it, the total amount of water retained in the black market was only 270 kilograms, which was far from the amount he needed!

If you don't have enough money, it's a bit troublesome...... This was the main material for some kind of trap he was going to make.

It stands to reason that although this material is relatively expensive, it is not too rare, and it is not very useful in organ warfare, so how can there be such a small stock?

Chang Ming bought all the two hundred and seventy kilograms of water retention gold, and was stunned by the large pile of metal in front of him.

Yu Haiyang watched Chang Ming buy materials one after another like this, spending a lot of money, but he didn't look as surprised as he was just now. On the one hand, the venue is different. In addition, Chang Ming was looking at what to buy just now, and now it is obviously purposeful. Impulsive surname consumption and destination surname consumption are not the same, like this, there are many middle and low-level stewards who come to purchase a large number of middle and low-level stewards, and no one will pay attention to him.

In Chang Ming's next plan, the proportion of water retention gold is quite large, and now the stock is not enough, and it feels a little troublesome.

What to do?

Chang Ming walked around in the metal material, and Yu Haiyang followed him loyally, not interrupting his thoughts.

After thinking about it for a long time, Chang Ming started again and bought more than a dozen kinds of metal materials. This time, he bought only one kilogram of each, apparently as a sample.

After buying the metal, Chang Ming went to other districts, and the same goods on the list were checked. In the end, there was still a part of it, but this black market in Qi Tiancheng was enough to meet Chang Ming's basic needs.

This time for the big shopping, Chang Ming spent a total of about 1.3 million gold coins, and Yu Haiyang's expression was very calm, as if this money was nothing to her at all.

But also, how much can the materials on the whole body of a strange beast be sold for? Just the sample he bought in the Ocean Alien Beast area just now, Chang Ming spent more than this amount!

The results were remarkable, Chang Ming retracted his gaze with satisfaction, saw Yu Haiyang at a glance, and said embarrassedly: "Ah, I want to be engrossed, I forgot that you are next to me!"

Yu Haiyang waved his hand nonchalantly: "No way, I just led you around, it's best if you have a harvest!"

She looked at Chang Ming expectantly and asked, "Will you come over again tomorrow? In two days, my second uncle and I will go back!"

Chang Ming was stunned: "You don't wait for the auction to end?"

Yu Haiyang shook his head: "These strange beasts can't be sold out in a day or two!" Uncle Lu has already given us the deposit, and after collecting the balance back, he will send people to our account in batches." We won't wait long here!"

Hit on the account?

This statement is too kind, Chang Ming thought for a while before realizing that the money bank is a chain, and of course the funds can flow between the money banks!

He said, "Okay, I'll come back tomorrow, and then you can walk with me again!"

"Okay!" Yu Haiyang replied very happily, she really cared about this rare friend she had made on land!

She is very arrogant in some ways, and the Yu family is a VIP merchant who has been working closely with the black market for a long time, so she doesn't have a pass in her concept at all, so she doesn't ask Chang Ming if she can come in tomorrow.

This matter was not a problem for Chang Ming at all, he nodded, walked to the cashier of the black market, and handed the list in his hand to the other party.

This place is really the same as a supermarket, the cashier lady quickly calculated the total amount of the goods, and said with a smile: "A total of 1,385,200 gold coins, is it to be paid now?"

Chang Ming nodded and said, "Yes, pay now." ”

The cashier lady said: "After half an hour, our people will drop all the goods at the pick-up office, and you can pick them up yourself." The free storage time is half an hour, and if you don't pick it up by then, we will transfer you to a paid storage warehouse for ten gold coins per hour. If you do not pick up your order within three days, we will collect it. Any more questions?"

Ten gold coins an hour, that's dark enough...... Chang Ming shook his head and said, "No, let's pay." ”

He took a money bag and counted out the corresponding amount of crystal cards to the other party, and the cashier's expression did not change at all, and she quickly accepted the points. Just by looking at her facial expressions, you can imagine how much turnover there is in this black market in a day!

After receiving the payment, the cashier handed him the pick-up card, along with two passes. A succinct sentence contains an explanation –

"Welcome to the next visit!"

Now that he already has a pass, Chang Ming is not in a hurry to sell the materials of the alien beast. He said goodbye to Yu Haiyang, waited for half an hour, picked up all the goods, hurried back to Xiao Shuxuan, and entered the organ room. When he was in the store, he had some new ideas and was eager to put them into practice!

He opened the virtual metal material training room that he hadn't used for a long time, there was a sample slot here, as long as the material samples were put in, the machine room would automatically scan and copy all the names of the materials.

Then, Chang Ming can do all kinds of work on these virtual materials, and it will feel exactly like the real thing.

Chang Ming put all the metal samples obtained from the black market into it, and after a while, the panel of the virtual training room showed the name and basic surname of the same metal, and Chang Ming could extract it at will.

Chang Ming extracted two things, one is called wind-milled copper, and the other is called Shentu tin. He pondered for a moment, took a certain proportion of each, threw them into the furnace, and began to smelt.

He stared at the furnace closely, constantly manipulating, carefully observing the changes in the two metals.

They melt and mix under the action of high temperature, and the two different colors gradually mix together and become a new color.

The system prompt rings in time:

【Achievement】Create a new type of material and increase your points by 100,000 points.

It worked!

He made bronze!

The first alloy in history!

When Chang Ming observed wind-ground copper and sunken tin, he found that the casteas of these two metals were very similar to copper and tin in the other world. He wanted to make alloys, and the first thing he thought of was to test these two materials.

Experiments have shown that although the metals of this world are more complex and diverse than those of the other world, and some of them have strange castes, they still have characteristics that are unique to metals.

By mixing two or more metals, it is possible to create new types of metals. The new metal has completely different characteristics from the previous ones, and even some characteristics that do not exist in ordinary metals!

That's alloy!

Yes, what should I do if the ready-made water retention gold is not enough? Chang Ming can make alloy instead!

Perhaps, the alloy made is better than the ready-made metal of water and gold!

Moreover, for Chang Ming, there is a more convenient place. That's that he has a virtual metal training room!

In this training room, he can use the sample to virtually produce metal for testing, which can save a lot of real metal without causing waste. In addition, the conventional characteristics of the metal can be inspected directly in the training room, making the alloy results more intuitive!

Moreover, he has long discovered that there is no multi-alloy in this world, at least, it has not been used in large quantities! In other words, the alloy itself, and even every alloy formula, is Chang Ming's unique capital!

In modern industry, materials are king, and in institutions, materials are king!

With a unique material that only belongs to him, Chang Ming has his own material capital!

Without a doubt, this is an extremely powerful advantage!

This whole night, another eighty hours, Chang Ming stayed in the organ room and did not come out.

He still started with bronze, and continued to increase or decrease the proportion of tin, recording the characteristics of different objects in bronze under different proportions.

After experimenting with bronze, he expanded his experiments to other metals.

The metal of this world is not only different from the metal of the other world, but also the surname and quality of the items are also very different. Chang Ming continued to experiment repeatedly, and a column of records appeared in the book, and each line of new text was a new alloy, and it was possible to turn it into a huge fortune in the future!

Throughout the night, this record continued to extend downward! )
