Chu Duan was alchemy in the alchemy room, while Nalan Fenghua and the others were waiting in the inner hall of the Xiao Dan Pavilion.

Time passed little by little, and soon, an hour passed, and within this hour, Xiao Dange did not even make any business, that is to say, within this hour, no one came here to buy pills.

I have to say that this is a kind of sadness, the pills sold by Xiao Dan Pavilion are of low grade, and there are mainly three kinds of energy pills, Jinchuang pill and blood tonifying pill, in addition to a small number of small Yang Dan.

The Energy Pill, the Jin Chuangdan, and the Blood Replenishing Pill were basically refined by Qin Yang, while the Xiao Huanyang Pill was brought by Nalan Fenghua this time, and there were not many.

Such a small Dan Pavilion is too weak to have any competitiveness, and it is only a matter of time before it closes.

......

In the alchemy room, the temperature is extremely high, and ordinary people can't bear it at all, even if it is an alchemy apprentice like Qin Yang, he will sweat profusely if he stays here for a long time, and he has to leave to rest and replenish his water, but Chu Duyun is light and breezy and will not be affected in any way.

At this time, he had already refined all four pills.

Energy Dan, Jin Chuangdan and Blood Replenishing Dan as well as Xiao Huan Dan.

With the inheritance of the secret book of pills, it also contains all kinds of memories, and Chu Duan's own comprehension can be called demonic, and his spiritual intention is even more powerful, above the ordinary alchemy masters, plus these elixirs refined, the level is extremely low, and Chu Duan will master it in an instant.

The first time he made an alchemy, Chu Duan succeeded.

There are 12 capsules in one furnace of the Energy Pill, 10 grains in one furnace of Jinchuang Dan and Blood Replenishing Pill, and 8 grains in one furnace of Xiaohuandan.

Chu Duan didn't know what the number of pills in one furnace was when other alchemists were refining these four pills, so he didn't feel much of it, and then, he discerned the quality of the pills.

"It's not enough. "Put down the four pills. Chu Duan shook his head slightly, obviously dissatisfied with this refining, if Qin Yang was there, he would definitely jump up in shock.

Take a little rest, and at the same time storm your head, recall every detail of the previous alchemy, like a replay, you can also see it clearly, and then compare it with the memories obtained by the inheritance, and find out your own shortcomings. Fix the shortcomings and try to do better next time.

"To improve the quality of the elixir, we must first start with the purity of the essence of the medicinal materials. Chu Duan said secretly, thinking about it, how to improve the purity of the essence of the medicinal herbs.

Thinking about it, Chu Duan suddenly thought of his own spiritual thoughts, and with the help of his spiritual thoughts, he could help with the extraction of medicinal materials, if he directly participated with his spiritual thoughts. Will it be able to improve again?

Thinking of this, Chu Duan thought about the feasibility again and immediately took action.

Taking out the five medicinal materials needed to refine the Energetic Pill, Chu Duan heated the furnace again. Then, the first medicinal herb was put in, and the spiritual mind entered the Dan furnace and began to extract the medicinal herbs.

Extraction of medicinal herbs for many times in a row. This time he was more skilled, and Chu Duan took the initiative to directly participate with his spiritual thoughts, infiltrating the inside of the melted medicinal herbs. Combined with the technique and high temperature, the impurities in the herbs are eliminated.

Direct involvement with a spiritual mind is more efficient.

After the extraction was completed, Chu Duan took out this group of medicinal essence and identified it, and found that the purity of the essence was ninety percent five, which was 0.5 percent higher than before, but compared to ninety percent nine, it was not enough.

Next, Chu Duan was not in a hurry to refine the elixir, but specialized in extracting the essence of medicinal materials, there are many medicinal materials here, all of them are low-grade medicinal materials, and their value is not high, which is a good place to practice.

The continuous extraction and the participation of spiritual thoughts again and again made Chu Duan more and more proficient in extracting medicinal essences.

Two hours passed in a flash, and within these two hours, Chu Duan had taken more than three hundred kinds of medicinal essence from the essence, and his proficiency had greatly improved, and the purity of the essence of the medicinal essence had also reached ninety percent and seven, and at the same time, the speed of extracting medicinal materials had also been greatly improved, and the time had been reduced by one-third.

Obtaining the inheritance, coupled with the cooperation of his own demonic understanding and strong spiritual intent, the improvement of pure medicinal materials in just two hours is enough to completely defeat the efforts of ordinary alchemists for more than ten years.

Chu Duan was busy inside, and the people waiting outside were impatient.

"Qin Yang, how much time do you need to refine a furnace of energy pills?" asked Nalan Fenghua.

"Energy Dan...... Half an hour......" Qin Yang was stunned for a moment and replied.

"What about the other pills?" asked Nalan Fenghua again.

"It takes an hour for both the Jin Chuang Pill and the Blood Replenishing Pill, and the Xiao Huan Dan has not yet been successfully refined. Qin Yang said.

Nalan Fenghua nodded, Chu Duan entered the alchemy room, and three hours had passed, and there had been no movement.

Immediately after, another hour passed, and at this hour, Chu Duan still took the essence of medicinal herbs, and it was the energy pill.

Because of the breakthrough of the bottleneck, the five medicinal essences of the Energy Pill have reached ninety percent nine, as for ten percent, it is too difficult and too difficult, even if it is the inheritance obtained by Chu Duan, the great alchemy master is only ninety percent nine.

Five medicinal essences with a purity of ninety percent and nine percent of them, Chu Duan began to use these five essences of shocking purity to refine the elixir.

The second time he refined the Energy Pill, combined with the previous shortcomings, Chu Duan was confident that this time he could refine a better Energy Pill.

Once again, the spiritual mind was directly involved, and I watched the fusion process of the five medicinal essences at a deep level, which was vivid.

This feeling is very peculiar, and Chu Duan's basic alchemy technique is also much more proficient, and it is easy to make it, and the combination of inside and outside makes the formation speed of the energy pill significantly improved.

In about five minutes, the essence of the five medicinal herbs was completely fused and coagulated, forming one pill after another.

When the Dan furnace was baked, Chu Duan already knew that this time the number of Cheng Dan was higher, reaching fifteen grains.

Each energy pill is the size of a soybean, with a delicate, smooth and round appearance, and it looks very attractive, but there is no fragrance of the elixir.

After discerning, Chu Duan nodded, the energy pill of this furnace is indeed higher than the energy pill of the first furnace, and the number of Cheng Dan is also higher.

He suddenly remembered that he had been in the alchemy room for several hours, and he should go out to let them see this elixir.

Thinking about it, Chu Duan walked out of the alchemy room with five bottles of pills and went to the inner hall.

Seeing Chu Dui appear, everyone was stunned at first, Nalan Fenghua quickly stood up, and looked at the five porcelain bottles in Chu Duan's hand with a hint of expectation.

Chu Duan placed five porcelain vases on the tea table in the inner hall.

"These are ......," Nalan Fenghua sat down again.

"Pills. Chu Duan said lightly.

Qin Yang looked at Chu Duan, and then at the five porcelain vases.

Nalan Fenghua picked up one of the porcelain bottles, pulled the cork up, and with a pop, there was a very faint fragrance of pills wafting out, if you don't pay attention, you won't notice it.

"Why doesn't there be the fragrance of the elixir?" the maid Xiaohuan sniffed hard: "It turns out that there is, but why is it so light? Is it a waste pill?"

Nalan Fenghua poured out a pill, and everyone's eyes suddenly fell on the pill.

"Energy Dan!" everyone shouted, and immediately their faces changed greatly, and a trace of disappointment flashed on Nalan Fenghua's face.

The Energy Pill, a pill, is the lowest grade of all the pills, and its value is not high.

"I thought there was some surprise? it turned out to be the lowest level of energy pills. The maid Xiaohuan said sarcastically.

Qin Yang stared at the goose-yellow energy pill without blinking, and gradually, his eyes became solemn, and he strode over.

"Miss Nalan, can you show me the pill. As he spoke, Qin Yang's tone trembled slightly.

Nalan Fenghua handed the pill to Qin Yang, Qin Yang carefully pinched it, first sniffed it close to his nose, only felt a faint fragrance of medicine, which shocked his spirit, and then, he carefully stared at the pill in his hand, looking at it from all angles, the more he looked, the more excited he looked.

"Master Chu, may I ask if this is a flawless quality energy pill?" The excited Qin Yang suddenly turned to Chu Duan, bowed deeply to Chu Duan, and at the same time shouted out the title of Master, and the words he said made everyone present stunned, and then shocked.

The business of the Nalan family is dominated by pills, although Nalan Fenghua does not know how to make pills, and there is no outstanding point in distinguishing pills, but he is very familiar with the basic knowledge of pills, as her maid, Xiaohuan also has some understanding of pills, and the shopkeeper of these, because of the elite pill shop, naturally has to understand.

The so-called flawless quality refers to the quality of the elixir.

For the same pill, according to the purity of the essence of the medicinal materials before refining and the techniques in the refining process, as well as the difference between the most refined pill and the final pill, etc., there will be different qualities, from low to high, which can be divided into five quality levels: rough, ordinary, sophisticated, flawless, and perfect.

The quality of the pill affects the efficacy of the pill and the amount of erysipelas.

Although the pill is the essence of the herb, it also has a slight toxicity, and it is not good for the human body to take it many times, so the higher the quality of the pill, the less erysipelas, and the greater the degree of efficacy.

It is said that if the quality of the pill reaches perfection, there will be no erysipelas, and the effect of the medicine will be ten out of ten.

However, the perfect quality elixir is a kind of legend.

The quality can reach flawless, that is already the sky, like Qin Yang, an alchemy apprentice, most of the energy pills that are refined, most of them are just rough quality, and if you play well, you can reach ordinary quality.

The flawless quality pill was in his hand, and each one of them was excited, very excited.

Nalan Fenghua quickly opened the corks one by one, and poured out pills one by one, in addition to the Energy Pill, there were also Jinchuang Pill, Blood Replenishing Pill and Xiao Huan Pill, after Qin Yang's identification, they all reached flawless quality.

The fifth porcelain bottle was opened, and a pill was poured out, which was also goose yellow, and it looked like it was the Energy Pill, but under Qin Yang's recognition, the whole person trembled violently because of excitement.

"End...... Finish...... Perfect...... Quality ......" Qin Yang trembled like a sheep's madness, his eyes widened, he stammered and pointed to the energy pill in his hand, and said with great difficulty, and suddenly, the inner hall exploded. (To be continued......)
