Roy took a deep breath and said, "It's you!"

"Elemental Cultivation Liquid, suitable for use by spiritual rune cultivators below the second order. Medicinal materials needed: First Order (or Second Order, choose according to your own strength.) The corresponding element of the Demon Beast Crystal, the marrow washing grass, the ventilation grass, and the strong bone flower. How to use, the three medicinal materials are decomposed and fused with alchemy according to the ratio of a magic crystal, 500 grams of marrow washing grass, 350 grams of ventilation grass, and 200 grams of strong bone flower, and the synthesized powder is dissolved in a one-liter fixed volume bottle. Each time you use it, take 100 ml in a large basin of hot water and soak it while meditating and cultivating. ”

Roy showed Kemesri the prescription. Kemisri thought for a moment, looked at Roy in a bit of shock, and asked, "Thunder Elemental Rune Spirit Cultivator?!"

Roy nodded a little awkwardly. As we all know, under normal circumstances, only the light element and the wind element can condense a cultivator into a spirit rune.

"Heavenly genius. Kemisri took a deep breath and said, "I will definitely live up to Peter's expectations and teach you alchemy." ”

Roy was a little embarrassed about why Camesri seemed to be as crazy about knowledge and education as Peter.

"Without further ado, let's go to the herb store and have a look. Camesri didn't know why he was more anxious than Roy.

Of course, alchemy is still an emerging academic for now, so there are very few alchemists on the Kainoran Continent at present, and the alchemists of the older generation are complacent, resulting in not many medicinal herb shops, and only one in the entire Demon Cloud City sells medicinal herbs. Because alchemy must be based on alchemy, the threshold for alchemy has become very high.

In many cases, the owner of the herb store may not have seen some medicinal herbs.

However, the medicinal materials used this time are obviously relatively low-level. These medicinal herbs are usually very common in the Demon Cloud Mountain Range, but no one knows what their specific functions are. If it weren't for the fact that this book says "marrow washing grass, aeration grass, and strong bone flower," neither Roy nor Kemisri would have known that these flowers and plants had such strange names.

As for the magic crystal of Warcraft, you need to find it at the auction house or issue a mercenary mission to find it.

These low-grade herbs were quickly bought by Roy in proportion to a total of ten kilograms. It should be a serving of ten. Roy put the herbs into the Void Ring at the Herb Shop, costing a total of forty-five silver coins. Then, Roy and Camesri rushed directly towards the Demon Cloud City Auction House.

The auction house in Demon Cloud City was opened here by a large family in the Stardust Principality. The City Lord of Demon Cloud City didn't have that financial resources. The funds used to open an auction house, Roy conservatively estimates that with the auction behavior of Demon Cloud City as an example, there may be sixty or seventy thousand gold coins circulating in a day.

Roy thought about it, Elusa fire attribute, Genosis, Blake light attribute, and he is a thunder attribute, so it's good to buy these few. (A careful look at the children's shoes should have been discovered, the prescription said that it could only be used on Spirit Rune cultivators, and Elusa ...... ）

Roy and Kemisri came to the auction house, and after being introduced by the maid here, they learned that the auction house is divided into two parts, one is the exchange and the other is the auction house. The procedure of the exchange is as follows: generally, if there is something you want to sell, you can come to the exchange in the auction house for valuation, of course, the actual price is set by yourself, and the valuation given by the staff of the exchange is only for reference and advice. If it is confirmed, it will be listed on the exchange in the form of a commodity. Once the transaction is successful by the customer who came to look for the item, the money will be collected by the consignor himself, or the consignor can register the stored value card number, and the money for the item sold will be credited to it.

The exchange transaction tax is calculated at five percent, and this transaction tax is counted as the income of the auction house.

The auction house, on the other hand, is only open from 7 to 9 p.m. In the case of an auction, the seller makes an appraisal in the auction house, and the appraisal is the starting price set by the appraiser of the auction house, and if the seller is not satisfied with the starting price and thinks that it is too low, the auction cannot be carried out. Of course, if the seller feels that the starting price is too high, they can take the initiative to lower it.

The auction house is a kind of bidding activity, so assuming that it is a very rare item, the income from using the auction house is much higher than that of the exchange route.

The transaction tax on auction houses is three percent.

It is equivalent to: the auction house has two departments: the auction house and the exchange, while the exchange is opened all year round, and the auction house is opened in a fixed period of time, with different functions.

Like those magic crystals of Royti, the maid suggested going directly to the exchange to find them. Although the first-order magic crystals are relatively few than the second-order magic crystals, they are not uncommon.

It's a pity that Roy found that the Light Elemental Crystal was very expensive. The fire element, thunder element, water element, and price are about the same, and the earth element and wind element are the cheapest. The main reason for this situation is that the number of light elemental demonic beasts themselves is scarce, and the other is that the demand is relatively large, after all, knights are the main rulers of several empires.

What Roy saw on the exchange, the light element magic crystal, the cheapest is a hardware coin. The magic crystals of the thunder element and the fire element are much cheaper, two gold coins each. And the Earth Elemental Magic Crystal is the cheapest, only fifty silver coins. Anyway, the Wind Elemental Demon Crystal also needs a gold coin.

Of course, these are all first-order Warcraft Crystals, and the price of high-level is definitely more expensive.

Roy asked Camesri why the Earth Elemental Crystal was so cheap.

"That's because, this is the Shengyao Empire! The land here is the most suitable for the growth of earth-attribute demonic beasts. Because of the large output. Kemesri explained.

"That's it......" Roy was helpless, and he didn't hesitate to buy four light element magic crystals, two thunder element magic crystals, and two fire element magic crystals.

He must have forgotten that Elusa was not a spirit rune cultivator, otherwise why would he buy a fire elemental magic crystal?

A total of thirty-two gold coins were spent.

According to the maid of the auction house, this is already considered a ...... The wealth is deep. Thirty-two gold coins is already a lot, and for an ordinary family, this money can feed and clothe for several years.

After buying all the materials, Roy also returned to the third floor of Peter's Library, in their lab, accompanied by Camisry.

Roy roughly explained his experience when refining medicine for the first time to Kemesrui, it was very detailed, and no details were missed, including that the power of the thunder element was too high, which would burn the medicinal herbs and so on.

Subsequently, Roy and Kemesri divided the herbs into small portions according to the proportions according to what the book said, and the pretreatment required grinding, which was a waste of time.

Luckily, Peter bought Roy several mortars, so the two of them were more productive when they were separated.

It took the two of them almost an hour to grind a dozen kilograms of herbs into the powder they needed. Kemisri thought for a moment and asked, "Which elemental do you want me to try to refine first?"

After pondering for a moment, Roy said, "The thunder element and the fire element can also be used, because the magic crystal of the light element is too expensive, and it is only refined in the end." ”

Roy's analysis is very spot-on.

According to Roy's previous experience in alchemy, Kemesrui began to decompose the medicinal powder.

Seeing this, Roy also watched very quietly.

However, how to decompose such a magic crystal? It is not right to grind, grinding will cause the elemental energy in the magic crystal to be lost. Roy and Camesry looked back at the book for a long time, but said they were going to wrap it in dirt to decompose.

"Is it so weird?"

Dirt is not hard to find. Roy quickly dug some outside and came back. According to the book, the earth is first wrapped in the thunder elemental magic crystal, and then it is decomposed by alchemy.

Kemesri did so. He used a large cauldron to hold the Thunder Elemental Crystal, and then put dirt into it.

Then he put the crucible on the decomposition formation.

Because Kemisri is just a normal thunder elemental magician, not a thunder elemental rune cultivator, when he uses alchemy, he must use an alchemy array to assist.

Obviously, Camesri's spiritual power is not comparable to Roy's, far above Roy's. In just an instant, the alchemy array reacted, and the thunder and lightning the thickness of a pencil tumbled in the formation.

It was only a moment before Camethry stopped moving. He suddenly paused, "I see...... Hey, wait!"

Seeing that Roy tried to push away the dirt, Camesri immediately stopped him. Kemesri said, "This dirt cover is to prevent the decomposed Thunder Elemental Crystal from collapsing when it comes into contact with the air!

The two of them went back to the book.

Kemesrui thought for a moment, and then said, "The next step should be to fuse the three herbs first, and finally mix the decomposition of the Thunder Elemental Demon Crystal with the herb fusion. ”

Without saying a word, Kemesri hurriedly put the herb powder that had been processed into the synthesis formation.

And Kemesrui's spiritual power was very strong, and it only took about ten minutes to refine this level of medicinal powder. This is something that Roy is far behind. Looking at the synthesis speed of Camesri, Roy helplessly wiped the cold sweat from his forehead.

Eventually, according to some of Kemesri's alchemy experience, he first put the synthesized powder into an Erlenmeyer flask, and then, he also looked a little nervous.

The crucial step has arrived.

Throw the Thunder Crystal disintegration from the cauldron into the Erlenmeyer flask.

If it fails, then all the work done is wasted. And this step is entirely a matter of luck, not an alchemical reaction. So even if Kemesri's mental power is very high, it depends on luck at this point.

Of course, if the refining powder is of high purity, then the success rate of this step is relatively high.

"Roy, stay away. ”

Camesri was afraid that if this kind of thing did not succeed in contact and fusion, it would fail and explode. Seeing that Roy was already hiding, Camesri slowly raised the crucible, tilted it sideways, and poured it into the Erlenmeyer flask.

And the decomposition of the thunder elemental crystal...... It's liquid, and it looks like plasma. The liquid seeped out of the dirt that covered it at an angle as the crucible tilted, strangely not taking away a single bit of it. As soon as these plasma come into contact with the air, this thing begins to evaporate as smoke visible to the naked eye. Kemesry took a deep breath, increased the angle of inclination, and after pouring it at once, quickly capped the Erlenmeyer flask.

"Squeak! squeak!"

The plasma that was poured into the Erlenmeyer flask actually squeaked when it came into contact with the powder. The contents of the Erlenmeyer flask jumped and jumped.

It took about another five minutes for the Erlenmeyer flask to go silent.

At this time, Roy walked over from the side and carefully looked at the product inside the Erlenmeyer flask.

A light blue liquid with a smoky color. Obviously, this bottle of stuff has stabilized. However, it is still relatively volatile. After quickly completing the volume with water, Kemesri found that the diluted light blue liquid no longer emitted smoke.

"Huh...... Both Kemesrui and Roy breathed a sigh of relief, refining the Thunder Element Pei Yuan Liquid for the first time, and actually succeeded in the first attempt!
