Under the leadership of Nalan Fenghua, Chu Duan came to Xiao Dan Pavilion, accompanied by the maid Xiaohuan and two guards.

Along the way, Nalan Fenghua simply introduced Xiao Dan Pavilion to Chu Duan, so that Chu Duan had a more intuitive understanding of Xiao Dan Pavilion, and after that, he even called out the personnel of Xiao Dan Pavilion to let Chu Duan know a thing or two.

The Xiaodan Pavilion is indeed small, with a total area estimated to be less than a hundred square meters, and it is divided into three parts, one is the shop, one is the alchemy room, and the other is the inner hall.

In the Xiao Dan Pavilion, there is a shopkeeper and a buddy and an alchemist, the shopkeeper has met Chu Duan before, the buddy is a young man in his twenties, his cultivation is not high, and the sword qi realm is at the eighth level, as for the alchemist, it is actually a highly praised title, because he is just an alchemy apprentice.

Get to know each other, the shopkeeper and the guy are busy, Nalan Fenghua briefly introduced Chu Dui, and then asked the alchemy apprentice to take Chu Dui to the alchemy room, and they waited in the inner hall.

Alchemists have a rule, when alchemy, others are not allowed to watch, one is to prevent their own alchemy techniques and skills from leaking, and the other is to be afraid of being disturbed, resulting in the failure of alchemy.

This alchemy apprentice is called Qin Yang, thirty-eight years old, without a teacher, his alchemy is seven or eight years of collecting all kinds of alchemy-related books and items, through uninterrupted efforts, little by little attempt, simply put, he is a wild road, without any guidance, nor any formal learning.

When he knew that Chu Duan was an alchemist, he was very respectful to Chu Duan.

The alchemy room of the Little Dan Pavilion is quite small, surrounded by shelves, on which some medicinal materials are placed, and in the middle there is a bronze Dan furnace, under which there is ink carbon, which is one of the types of charcoal that can burn for a long time and at high temperatures, and is generally used exclusively for alchemy.

"Usually, what kind of pills do you refine?" Chu Duan asked lightly. It seems to have the bearing of a master.

"Energy Pill, Jin Chuang Pill, Blood Replenishing Pill, and now I am trying to refine the Xiao Huan Pill. Qin Yang replied truthfully.

"Is there a Dan Fang, give it to me. Chu Duan said.

Without hesitation, Qin Yang took out four Dan Fang from the shelf on the side.

This pill, in the hands of ordinary people, is relatively precious, but in the hands of alchemists, the value is extremely low, because of these pills. They are all very low-grade pills, like the Energy Pill, which is a first-grade pill, and its main effect is to restore physical strength.

Jin Chuangdan and Xuebu Dan are two kinds of pills, which are mainly used to treat trauma and replenish blood.

As for Xiao Huandan, it is a three-pin pill, which is mainly used to treat internal injuries.

After studying for more than ten years, he has only been able to refine the Energy Pill and the Golden Creation Pill and the Blood Replenishing Pill, which shows how miserable Qin Yang is.

Think about it, too, alchemy. Not everyone can, it is required to have enough talent, in addition to talent, to have enough resources, and so on.

Talent. Qin Yang did have some, but the resources were seriously insufficient, lacking the guidance of a true alchemist, and lacking formal learning. Under all these constraints, even if he spends a few more years, at best. It's just that he's more proficient in refining those energy pills.

"Alright, you can get out of the city first. Chu Duan said while looking at Dan Fang.

Qin Yang's expression was stunned, his expression couldn't help but be a little gloomy, before Nalan Fenghua said that Chu Duan was an alchemist, coupled with Chu Duan's extraordinary bearing, Qin Yang instinctively felt that Chu Duan was extraordinary, and planned to stay here and watch one or two, maybe it would be very helpful to him, but now when he heard Chu Duan's words, he felt hopeless.

To be honest, Qin Yang was extremely eager to get the guidance of a true alchemist, even if it was just watching from the sidelines, and he was willing to pay any price for it.

It's a pity that every true alchemist is very noble, and he simply looks down on an apprentice like him who is a wild man, so that he doesn't have any chance.

Qin Yang, who had a gloomy expression, left the alchemy room, and his mood changed, Chu Duan felt it, but he didn't care.

Four Dan Fangs, Chu Duan glanced at them, and wrote down all the contents.

Among the inheritances he obtained, there were no such pills, and Chu Duan was not ready to refine the inherited pills, at least not for now.

The first is the Energy Pill, according to the records on the Dan Fang and the inheritance of the Secret Book of the Pill, Chu Duan immediately found the corresponding medicinal materials on the wooden shelves around him.

The Heavenly Desolate Realm is definitely related to the Archean Realm, so in the inheritance that Chu Duan obtained, the memories of hundreds of thousands of medicinal materials are also applicable to the Heavenly Desolate Realm, at least most of them are similar.

After preparing the medicinal materials of the Energy Pill, Chu Duan began to light the ink charcoal, heat the bronze Dan furnace, and then, when it was time for the hot furnace, he closed his eyes and recalled the techniques of alchemy and the records on the Energy Pill formula.

Half a quarter of an hour later, the bronze Dan furnace was hot enough, and Chu Duan opened the lid of the furnace, and a stream of hot air suddenly emanated from it.

Immediately, according to the records of Danfang, Chu Duan began to put medicinal materials in an orderly manner.

There are five kinds of medicinal materials in total, and they should be put in order, and the amount is also precisely specified.

Alchemy is to remove impurities from various medicinal materials, extract the essence of them, and then fuse these essences in a certain way.

This so-called method is the technique and technique of alchemy.

Without alchemy techniques and techniques, the essence of medicinal materials can also be fused, but that is the most superficial fusion, and the final formation cannot be called an elixir at all.

The so-called elixir is the aggregation of the essence of various medicinal materials, and then produces some kind of favorable change, and the superficial fusion is like a patchwork, which will not produce qualitative changes at all, and it is useless.

Chu Duan put in the first kind of medicinal material, covered the furnace lid, and began to burn the medicinal material at a high temperature, completely locked the furnace lid, and urged the flame of ink and carbon to increase it to the maximum, and the temperature continued to rise inside the entire bronze Dan furnace.

And Chu Duan's spiritual thoughts spread out, seeping into the inside of the bronze pill furnace, and under the scorching heat of the high temperature, there began to be signs of melting.

When the medicinal herbs began to melt, Chu Duan waved his hands and continued to slap on the bronze pill furnace to control the burning temperature of the flames.

If the herbs are kept under high temperature burning, the herbs will be burned.

It is necessary to control the temperature.

......

"What? He asked you for Danfang?" In the inner hall, Nalan Fenghua was shocked when he learned about the situation, and the others also looked at each other.

"Miss, I'll just say it, he is definitely not an alchemist, where is there an alchemist who does not have an alchemy furnace, and there is no Dan Fang, you must know that it is not a precious Dan prescription, but the most basic Dan prescription. The maid Xiaohuan found room to play again, and immediately crackled and said: "He must have lied to you, when the time comes, he will waste a batch of medicinal materials, and if he can't do it, he will blow up the furnace, causing losses, and he will also blow himself up to serious injury." ”

Nalan Fenghua didn't speak, bowed his head slightly, and was a little uncertain.

The shopkeeper sat quietly and did not speak, while the man stayed in the front shop, waiting for any business to come to the door.

Time passes slowly.

"Let's see. "Nalan Fenghua Road.

......

The spiritual power of an alchemist will be stronger than that of ordinary people, and Chu Duan's spiritual power will be much stronger than that of many alchemists.

His spiritual thoughts infiltrated into the bronze Dan furnace, and he was able to observe every change in the Dan furnace in detail, and, after trying, he was able to influence the purity of medicinal materials through his spiritual thoughts.

Ordinary alchemists, even alchemists, can't do this.

There are alchemy techniques on the outside, and spiritual ideas on the inside, combining inside and outside, so that the quenching efficiency of the medicinal materials is increased several times, and soon, the first medicinal materials are extracted one after another, leaving a ball of the purest medicinal liquid.

Chu Duan quickly opened the lid of the furnace, and directly took out the pure medicinal liquid from the Dan furnace with his spiritual thoughts, placed it in the container next to it, and stored it first, and then put in the second medicinal herb and began to extract it.

This is the step of the general alchemist's alchemy, first extracting the essence of each medicinal material, and Chu Duan is the first time to do alchemy, so follow the normal steps.

It didn't take long for all the five medicinal materials to be extracted into essence, and they were all essence with a purity of ninety percent.

It is important to know that the purity of each medicinal material has a degree.

Under normal circumstances, the essence obtained by the general alchemist extracting medicinal materials is about 50%, that is to say, it is also mixed with 50% impurities.

If you have enough experience and good techniques, you can improve the purity of the essence to the point of 60% or even 80%.

However, the higher the purity of the essence, the greater the difficulty, and if you are not careful, the essence of the herb may be destroyed under the burning of high temperatures, which is extremely risky.

Generally speaking, it is very difficult to achieve an essence with a purity of 80%, which is already surprising, and what a shock it is to reach 90%.

It's a pity that Chu Duan is not satisfied.

In the process of inheritance, the extraction of each medicinal material, the purity of the essence is higher than ninety, and even reaches the point of ninety-nine.

"Let's refine a furnace of energy pills first. Chu Duan said secretly, put the five kinds of medicinal essence into the bronze pill furnace again in order, and let the temperature of the ink charcoal burn at the level of a simmer.

And Chu Duan's spiritual mind entered the bronze Dan furnace again, and between the waves of his hands, he performed the basic alchemy technique, and with the cooperation of the inside and outside, the five medicinal essences in the Dan furnace began to approach each other and fused with each other, this fusion was a deep integration.

Chu Duan's hands waved continuously, using the basic techniques in the inheritance memory, with a total of thirteen movements.

Under the simmer, it is slowly calcined, and the spiritual intention helps to promote the fusion of medicinal essences.

Time passed little by little, and the five medicinal essences in the bronze pill furnace also penetrated each other and fused into a ball.

Next, it is necessary to completely fuse the essence of the five medicinal herbs to produce a qualitative change, and then let it solidify to form a real elixir.

As for how many pills can be formed after Cheng Dan, at present, Chu Duan can't be sure, he can only do his best. (To be continued......)
