Chu Chen entered the copper market, and when he looked closely, pieces of copper nuggets of different colors were placed on the ground.

Red fire copper, jade bronze, submerged copper, thick earth brass, cold ice blue copper...... , pieces of copper with different colors and properties dazzled Chu Chen.

These copper blocks are good things for casting weapons, magic weapons, and talisman armor, so the price is extremely expensive, and the cheapest piece of copper requires dozens of spirit stones. The good ones are incomparably expensive and have no boundaries.

Building a medicine furnace is not the same as crafting a weapon, and it is not that the more expensive the copper, the better. A really good medicine furnace must have good thermal conductivity, which can enable the alchemist to accurately control every minute of heat. On the other hand, these copper blocks cannot carry properties.

For example, Chilian Fire Copper, which is a copper block excavated from the bottom of volcanic lava, is born with a strong flame spiritual power. If you cast it into a weapon, it is extremely powerful, and you can even summon underground flames to help you in battle.

However, if it is cast into a medicine furnace, its fire attribute will appear too strong, and the rich geocentric flame power will completely incinerate the entire pill if you don't pay attention to it.

Chu Chen decided to open the spiritual sense and take a look at the quality of these coppers, and when the spiritual sense opened, he found that most of the copper emitted gray or white gas, and some of the more famous coppers, such as Xuanyu bronze was green, and Chilian fire copper was blue.

Chu Chen's gaze kept wandering and searching, and finally found a cloud of purple qi!

Gray, white, green, blue, red, purple, gold, there is copper that comes out of purple,

When Chu Chen walked up to a copper block the size of a basin and had a dark body, purple qi kept coming out of it, so strong qi.

"Boss, how do you sell this piece of copper?"

Chu Chen found that this was the only piece of copper in the entire store that did not have a price tag, maybe looking at its appearance, the boss didn't plan to sell it at all.

"This piece of copper is not for sale. ”

The shopkeeper of this copper shop is a young man, his expression is not shocked, no joy and no worries, as if this shop is not his, everything is according to the program, there is no room for negotiation at all.

He sat behind the counter, dozing off, opening his eyes for a moment, squinting back to sleep.

"Why don't you sell it?"

"This copper has no value, and I don't know what to plant, and we don't want to pit customers. ”

Chu Chen's questioning made the young shopkeeper a little impatient, opened his eyes, and frowned, "There are a lot of copper in this store, pick something else." ”

"Boss, you open a store to sell goods, I like this piece of black copper very much, make a price. Of course, Chu Chen couldn't let go of this piece of good copper that was bubbling with purple gas.

"Well, if you insist on buying it, then I can explain first, you won't return it when you go out. The young shopkeeper looked at Chu Chen with the eyes of a fool, "I will give you the lowest price, one spirit stone and one catty, and there is a scale next to you to weigh it yourself." ”

Putting his hands on this piece of black copper, a strange qi suddenly passed through his palms to Chu Chen's body, and he seemed to be holding a basin-sized "other world" with both hands.

What's worse is that this "other world" is still very heavy, and when it is put on the scale, the weight that comes out makes Chu Chen a little unbearable, 506 pounds.

"506 spirit stones, if you want it, I will charge a whole number, 500 spirit stones, this is a small profit, all the metals in the small shop are not bargaining, if you are dissatisfied, you can find another house." ”

The young shopkeeper glanced at Chu Chen, estimating that he would definitely not buy it when he saw this price, so he leaned on the shelf, squinting slightly and preparing to sleep.

"Boss, I bought it. ”

Although there was some pain in the flesh, Chu Chen did not hesitate, and it was possible to refine a little more elixir with five hundred spirit stones, but the copper stone with purple qi could not be found.

The young shopkeeper who received Chu Chen's 500 spirit stones still couldn't come back to his senses, because he didn't know if this young man who bought copper was a fool, and he was willing to pay the money.

However, if he knew the truth about this copper stone, I am afraid that the young shopkeeper would scold him for being a fool!

Chu Chen, who had paid all the spirit stones and put the copper stones into the storage ring, left the copper shop, and the next thing was to go to the blacksmith shop to build a medicine furnace.

As he came to Fang City more and more, Chu Chen was already very familiar with this place, and without much effort, he entered the blacksmith shop in Fang City.

The blacksmiths in the sect are different from the mortal world. Most of the blacksmiths in the mortal world are used to make tools such as scissors, sickles, hoes, etc., so they are very rudimentary. However, the blacksmith shop in the sect specializes in creating flying swords, magic weapons, armor and other protective things, which are the most important things for monks to save their lives, and they are naturally very important.

Therefore, the blacksmith shop is also one of the most wealthy shops in the market.

Each blacksmith shop is magnificent, and it looks like a small ancient palace. In fact, being able to open a blacksmith shop in the sect fang market of the Biquan Immortal Sect was basically impossible without a few brushes.

Coming to the most magnificent blacksmith shop in the entire Fang City, Chu Chen walked in excitedly: "Shopkeeper, I want to build a medicine furnace!"

However, I found that there were all kinds of monks in the shop, men, women and children, lined up in an orderly manner.

"I'm sorry, but there are too many customers at our store, and you need to make an artifact, so please line up first. ”

A girl in a yellow shirt who looked very smart stopped Chu Chen and pointed to the long line.

Chu Chen could only line up to the end of the line without temper, a famous store is a famous store, and if it can play good things, it is natural that there are many visitors, and of course, the price must be high-end and high-grade.

Chu Chen was only glad that he only needed an advance of a few dozen spirit stones at the beginning, otherwise he would not even be qualified to queue up now that he was shy in his pocket.

An hour later......

"Little brother, where did you get this fragment?" The white-haired old blacksmith frowned and looked at the purple-gold fragment in his hand, and shook his head helplessly, "This purple-gold fragment, no matter what method we use, it is impossible to melt it." If you can't melt it, how can you build it? Forgive the incompetence of the small shop, you better ask for another skill. ”

The largest shop in the city actually said that it was incompetent and could not melt it?

Is there any hope for yourself?

Chu Chen, who was full of black lines, could only quietly leave the blacksmith shop with the purple gold fragment in his hand.

Although he was happy to get the fragment of the Laojun furnace, he didn't expect a very important problem, that is, this fragment of the gossip furnace has been immortal and incorruptible for hundreds of millions of years, and this kind of quality alone is probably not something that ordinary people can make it melt!

It can't be melted, the fragment is always just a fragment, and it has no use other than being sharp.

What can I do?

In desperation, Chu Chen had no choice but to hold the mentality of trying, and walked to another blacksmith shop, this blacksmith master who had no guests to wait, but without saying a word, he picked up the hammer and hit it, and the sparks flew wildly.

As expected, despite all the methods, the blacksmith shop was still unable to deform the purple gold fragment in the slightest. Seeing this scene, Chu Chen couldn't cry or laugh. He had the feeling that he was hungry guarding the Golden Mountain. It's hard to get the baby, but it can't be refined, what's this called?
