"What weapons does this young man need to build?" The guy in the blacksmith shop couldn't help asking enthusiastically when he saw Chu Yun coming in.

This blacksmith shop is the largest blacksmith shop in Yangzhou Fucheng. Although its forging ability cannot be compared with the forging level of sects like Qingcheng, it is much stronger than ordinary small and medium-sized sects. At least it can forge low-grade treasure-level weapons here.

Chu Yun came here because he knew the strength here.

After all, the creation of the alchemy furnace itself is different from a weapon. The new alchemy furnace that Chu Yun figured out is essentially just an ordinary alchemy furnace. Although the materials are relatively precious minerals, the technical requirements for its creation are at most equivalent to the level of a low-grade treasure soldier. Otherwise, Chu Yun would not have chosen this blacksmith shop.

Of course, the alchemy furnace created by blacksmiths alone is not the final product.

After this guy asked, Chu Yun directly made his own request: "I want to build an alchemy furnace, with the specific sizes and specifications and materials on this piece of paper."

After saying that, Chu Yun handed over a dense design drawing.

"Alchemy furnace?" The guy was a little confused, but the person who was confused was not that someone asked their blacksmith shop to build an alchemy furnace, but that Chu Yun was so young that he was already an alchemist.

Thinking that the other party might be an alchemist, the respect on this guy's face became stronger.

However, after reading the materials listed on the paper, the guy couldn't help but open his mouth wide, and his whole face wrinkled together, as if he was constipated.

"This young man, are you sure you want to build an alchemy furnace in this way? Its price..."

"You don't need to worry about the price issue. I just want to know if you can build this alchemy furnace here."

When the guy heard someone suspected his blacksmith shop's skills, he immediately thickened his neck and said, "Of course it's no problem! Our Huangji Blacksmith shop is the best blacksmith shop in Yangzhou City."

"Okay, just build it according to this standard."

"This... Young Master, the young man needs to calculate the final cost of this alchemy furnace first. In addition, since the Young Master you created is a special item, you need to pay a 60% deposit first." The shop guy said.

A 60% deposit is definitely very high, and generally a 10% deposit is paid for a weapon.

But this is definitely understandable. As the shopkeeper said, an alchemy furnace is a special item. If the buyer doesn't want it after the blacksmith shop is built, the store will lose a lot. What's more, the alchemy furnace created by Chu Yun is indeed very special in materials. It requires the smelting and forging of seven precious minerals to create low-grade treasure soldiers. Only after thousands of tempering can the alchemy furnace be cast.

To forge low-grade treasure soldiers with this precious material does not require extreme tempering of these materials. For precious materials, the increase in the number of temperings will only increase the purity of the material, but it does not mean that the purer the material is, the stronger or sharper. Sometimes, materials that are too pure will be softer.

But alchemy furnaces are different. The alchemy furnace designed by Chu Yun does not need to be too strong, but must have sufficient energy permeability. This aspect is related to the purity of the material. The purer the material, the better the energy permeability.

Each of the seven materials chosen by Chu Yun has different qualities, but they all have one thing in common, that is, their permeability to energy is excellent.

For example, the iron of frost is extremely permeable to cold energy, but the rest of the energy cannot pass through. The copper of Yanyang is completely opposite to the iron of frost.

The fusion of these materials is the basis for Chu Yun to set up a formation on the alchemy furnace.

The formation chosen by Chu Yun is a formation called the spirit gathering array. This type of formation is not very common in the world. First of all, the skills required for the spirit gathering array are relatively high. Without a formation level above level 6, the spirit gathering array cannot be arranged. Secondly, the spirit gathering array itself does not belong to a large formation, and at most it is effective in the range of one or two feet in a radius.

Such a small formation is naturally impossible to assist in the cultivation of cultivation. More often, pharmacists use the spirit gathering array to cultivate medicinal materials. After the spirit gathering array is arranged around some small plants, the growth of medicine can be accelerated.

Correspondingly, this spirit gathering array is just right for use on an alchemy furnace. Of course, the premise is that the alchemy furnace is relatively small. If it is an alchemy furnace that is high by one person, it will not be possible to arrange the spirit gathering array.

Generally speaking, large-scale alchemy furnaces are most suitable for large-scale refining ordinary elixirs, while small alchemy furnaces are more suitable for refining extremely precious elixirs, so that the heat is easier to control.

The combination of the spirit gathering array and a small alchemy furnace is naturally used to refine precious elixirs. Therefore, there is no problem in this regard.

Finally, the waiter of the shop calculated and found that the cost of this alchemy furnace was as high as 10,000 taels of gold.

This is definitely an extremely high price. After all, a low-grade treasure soldier is only two or three thousand taels of gold. However, considering the materials and processes of this alchemy furnace, Chu Yun felt that this ten thousand taels would be kind.

Chu Yun took out a gold ticket of 6,000 taels of gold and handed it to the other party. The other party also gave him a certificate and asked him to come and get the alchemy furnace the day after tomorrow.

Chu Yun naturally had no meaning for this, and Chu Yun had no hope of getting the alchemy furnace immediately.

Then Chu Yun left the blacksmith shop and returned to the inn, with a large pile of medicinal materials piled up in the corner of the guest room.

Chu Yun is not idle now. He needs to re-select these medicinal materials and use the best-quality medicinal materials. After all, the Zhenqi Yuan Pill refined this time is an extremely precious elixir. If the quality of the auxiliary medicines causes problems with the alchemy, Chu Yun will be in tears.

In the past, Chu Yun had only refined elixirs twice to select medicinal materials. If it were ordinary medicinal materials, he would not have to do this at all. Knowledge was because they were both in the Qingcheng Sect, so naturally someone helped him select medicinal materials, and here he had to do it himself.

This is a very meticulous job. Chu Yun carefully observed each medicinal material and then selected it.

The True Qi Yuan Dan Speed ​​involves a lot of medicinal materials, and it took Chu Yun most of the time to choose them all.

Immediately afterwards, Chu Yun began to prepare for the subsequent manufacturing process of the alchemy furnace.

The alchemy furnace created by the Blacksmith Shop is just a semi-finished product, and Chu Yun also needs to arrange a formation on it.

This matter is very simple, which is to inlaid jade with different energy stored on the groove reserved in the alchemy furnace.

Jade is the most common item used to arrange arrays because it has the effect of energy storage. With jade not knowing the spirit gathering array, it can completely achieve the complementary effect.

A formation is a combination of points and lines. Points are the nodes of the formation, and lines are the lines of energy flowing when the formation runs.

When Chu Yun was building the alchemy furnace, the line was determined, and it was outlined by those special minerals. What Chu Yun needed to do was to place these points and install a total of 108 thumb-sized jade pieces on the alchemy furnace, so that the spirit gathering array would be completely laid out.

Chu Yun went to a jewelry store, spent only 200 taels of gold, and bought enough jade, and then returned to the inn to start carving according to the established appearance.

When setting up a formation, it is naturally impossible to simply place the items according to certain rules. If this is the case, it would be too simple.

The real difficulty inside is the patterned array base, that is, the items that form the array nodes.

Different formations have very different shapes, sizes and patterns of nodes. The higher the formation level, the more complex the patterns of these items, and the more stringent the order and thickness.

Even the engraving of some patterns requires the cooperation of internal force...

All of these things are not difficult for Chu Yun. He spent a whole day carving all the patterns of the formation base. It was lunch, so Chu Yun set out to the blacksmith shop directly.

At this time, the alchemy furnace had been built. After Chu Yun delivered enough gold tickets, he left with the alchemy furnace more than two feet high.

Although this alchemy furnace is not big, it weighs not low, weighing a thousand pounds. Fortunately, this weight is nothing to Chu Yun, so he took it back to the inn directly.

Now everything is ready, but the east wind is not available.

Without any hesitation, Chu Yun took out the cornerstone of the formation that had just been engraved and began to put it into the reserved holes on the alchemy furnace one by one.

The size of these holes is exactly the same as the foundation stone of the formation engraved by Chu Yun. With the clever design, it cannot be taken out after being put in.

When the last jade was put in, a blue light flashed across the surface of the alchemy furnace, adding a mysterious color to the entire alchemy furnace.

"It seems that it's time to give this alchemy furnace a name. Could this thing be the first alchemy furnace in the world with a formation?" Chu Yun's mouth raised slightly, and he felt proud.

Although it is easy for Chu Yun to integrate the formation into the alchemy furnace, this is not something that ordinary people can do.

First of all, when this idea appears, you must have a deep understanding of the elixirs and formations. Secondly, you also need to be very clear about the alchemy principles of the alchemy furnace, and you must also have extremely high formation cultivation. Finally, in the process of using this alchemy furnace to refine the alchemy, you also need to be very proficient in the operation techniques and alchemy techniques.

It is obvious that it would be good for people in the martial arts world to achieve some achievements in one of the alchemy or formations. Practicing two items is simply not something that humans can accomplish. If Chu Yun had not had two lives of souls and had already had a top-level medical profession as soon as he came to this world, he would probably not have chosen to practice the formation. In this way, it would naturally be impossible to make such an alchemy furnace.

"Just call it Qiankun Furnace!" Chu Yun raised his lips and gave it a grand name. Although he wanted to call his cauldron Qiankun Furnace, he still gave up after thinking about it. If he really wanted to choose this name, it would only add a joke.

"First refine a few ordinary elixirs to try the effect." Chu Yun made a decision in an instant.

He was not kicked by the donkey in his mind, so it was naturally impossible to directly refine the True Qi Yuan Pill using this newly created alchemy furnace.
