Zhao Xuan scratched his head and frowned and thought about it, until he was a long time old, and then he put it down and started the second experiment.

Another red grass entered the Dan furnace, a section of eight layers and six points, this time it melted faster, and the impurities were soon gone, the same as the situation just now, this time immediately opened the Ding furnace to collect, the perfect essence essence!

After pausing for a moment, I thought back to the difference between the two practices and found that the timing of the collection was different.

Another test, waiting for a breath to be collected, the liquid medicine is intact; Try again, wait for two breaths, still intact; Third, fourth...... Until the fifteenth breath starts to have problems, the sixteenth breath is scrapped by two percent!

It can be inferred from this that the time for purification to be completed is also limited. Otherwise, the purified liquid at high temperature will come into contact with the aura for too long, and it will destroy something.

He took out a new jade slip and wrote, "Chiying grass, the temperature is eight layers and six minutes, and after the purification is completed, it will be collected within fourteen breaths, and the fifteenth breath will begin to be damaged, and then it will be scrapped for every one breath delayed." ”

Zhao Xuan was happy to experiment, and every time he completed a herb, he would carefully record it, and then replace it with another herb, repeating it constantly.

There are also times when the spiritual power can't keep up, so I stop and meditate to recover, and in the process of recovery, my mind begins to recall what I have gained before. With the support of the Demon Pill, the divine soul power has recovered far beyond expectations.

"Winter vermilion grass, the temperature is one layer and three minutes, and it will be collected within fifty breaths after the purification is completed, and then it will be damaged by one percent for every three breaths."

"Bone-setting grass, the temperature is six layers and two minutes, and it will be collected within thirty breaths after the purification is completed, and then it will be scrapped for every five breaths delayed."

"Silver leaf grass, the temperature of the second section of nine layers is one minute, after the completion of purification, it will be collected within five breaths, and then it will be scrapped for every one breath delayed."

"Return the blood grass, the temperature is two layers and four minutes, and it will be collected within ten breaths after the purification is completed, and then it will be scrapped for every two breaths delayed."

……

The various data of low-level herbs were constantly improving, and Zhao Xuan was also extremely satisfied in his heart. However, every herb is carefully guarded for fear of making mistakes.

I don't know how long it took, Zhao Xuan took out a blood algae, which was the material of the blood return pill used in the liquid realm.

The temperature increased little by little, and there was no reaction at all, until the temperature reached the second stage and seven layers. With a hula call, the algae directly began to melt in large quantities, and the temperature rose to eight layers of impurities and was discharged.

After receiving it, I carefully compared it with the description of the jade slip, and found that there was a big difference. The color is not pure enough, the melting is not thorough enough, and some parts are a little burnt.

Take out a strain of Rheumatis again, the temperature rises directly to the second section of seven layers and five minutes, all melted, no burning, and still contains impurities; Test again, directly raise to the second section of seven layers and six points, all melted, no scorching, no impurities, perfect purification; Then another test, seven layers and eight points, no impurities and a little burnt; Seven layers and nine points, no impurities, began to appear noticeably burnt.

After making the record of the blood algae, Zhao Xuan pondered, the blood algae is raised to the right temperature before it reacts, what about the rest?

Some of the temperature increases slowly, and it is impossible to increase it little by little during alchemy, but in one step, so is the herb in front of it feasible?

Thinking like this, our Great Sect Master Zhao began to take out the Chiying Grass from scratch again and start experimenting!

……

Zhao Xuan completely threw away everything he knew before, and only recorded the current test results, constantly devouring these data like a sponge absorbing water, and constantly accumulating.

Fortunately, there are a lot of basic herbs, otherwise each plant would be gone before the results can be obtained!

……

"Green radish, the temperature is four sections and eight layers, and it will be collected within ten breaths after the purification is completed, and the temperature can be in place in one step!"

Finally, all the herbs on hand have been purified, and all that remains is some medicinal stones.

Although there are not as many types of medicinal stones as Dan grass, they cannot be ignored. The medicinal stone plays a vital role in the formation of the liquid medicine into a pill and the improvement of quality. Some high-level pills don't need pill stones, but for low-level pills, many pill stones are indispensable.

It's a new round of experiments, and the medicinal stone is not as easy to purify as the herb, and the smelting lasts longer! Moreover, during the refining process, there will be some slight collisions with the Dan furnace, and the residue after purification must be specially treated to remove it! This is also something that cannot be rushed.

The temperature required by the medicinal stone is obviously higher than that of the medicinal herb, and it is also more troublesome, but Zhao Xuan is very patient. No matter how detailed others tell them, they don't have a direct experience, and the effect is good.

……

"Haha...... It's finally done! Zhao Xuan jumped up excitedly and kept waving his fists.

Even those medicinal herb stones with higher temperature requirements and higher grades, Zhao Xuan also completed the purification with the help of two sharp weapons.

At this point, more than half a year has passed! Zhao Xuan didn't notice it.

I stretched my waist and saw that the ring was basically full of bottles and jars of liquid medicine, and my heart was full of joy and satisfaction!

As for the damage to nearly forty percent of the herbs, Zhao Xuan didn't pay attention to it at all, although the loss value was painful enough, but it was still acceptable compared to the harvest!

The pinnacle of the pharmacist is to be able to complete the purification of the aura realm elixir. The next step is to successfully refine the elixir and become an alchemist.

The alchemist corresponds to the aura realm and the liquid realm, and the elixir within the four grades. After that, it is the alchemy master, corresponding to the Zhudan realm and the star realm, that is, the five and six pins of pills. After that, it is the alchemy master, corresponding to the Xingyang Realm, that is, the seven-grade and eight-grade pills.

There is also a product, nine pins of pills. Those who can refine the Nine Pins Pill are directly called Grandmasters.

Zhao Xuan's goal this time was to be able to refine the second-grade peak Chengye Pill and prepare for refining the fourth-grade Red Soul Pill.

"Finally, and most importantly, the liquid medicine is mixed into a pill, and if it is successful, it will be much smoother! As long as the same elixir makes me successful once, this elixir will no longer be a problem for me in the future! ”

Zhao Xuan is still full of confidence in this point.

After recovering to the peak in all aspects, he began his first alchemy.

Facing the Dan furnace, take out all the medicinal liquids needed for a set of Dan. Carefully recall the introduction of the alchemy link in the jade slip.

I sketched the appearance of the Dan furnace in my mind, and constantly simulated it. From the beginning to the final alchemy technique, the details of the collection of the knot pill and the cheng dan are not let go, and it is only when they are sure that they have mastered it that they start.

Each has its own methods, but Xue Fengchen only used a set of seals called "Heavenly Gods and Buddha Hands".

The hands of the gods and Buddhas, the seal of the Dan into the Dan, it is easy to practice, and it only needs to be sealed one by one according to the technique. It is still a kind of sealing about seals, so it requires understanding and cultivation.

……

More than a dozen jade bottles containing medicinal liquid, such as Chiying grass, Huang Lingshi, and a set of birds, were poured into the Dan furnace in order.

Zhao Xuan was cautious and kept fighting.

……

A few days later, Zhao Xuan laughed like a madman.

"It's done, haha...... It's done, I finally refined the first pill in my life, haha...... Now this sect master is also an alchemist! ”

As soon as the unicorn fire was closed, Zhao Xuan danced excitedly. He carefully looked at the three pills in his hand, and smiled from ear to ear. Although it is only the lowest-level Hui Li Dan, and it is still a low-grade product, Zhao Xuan's heart is still beautiful.

It's hard to get started! Although the pill is not good, the meaning of the representation is different. This is an important step on the road to Dandao.

"This time, there are only three pills, and they are still low-grade pills. Next time, after the correction, it should be able to reach nine. Hui Li Dan is still the lowest level of elixir, and it is of no use to me. ”

Zhao Xuan cherished it, put the three Huili Pills into a jade bottle, and put them on a stone shelf in the ring. After relieving for a while, he cleaned up his mood and began to refine the pill again.

On paper, I finally feel shallow, but now I really know the difficulty of alchemy by myself. Therefore, it is better to be more committed and more serious.

Skillfully pointing to the Dan furnace, a purple flame was suddenly generated under the Dan furnace, and after a dozen breaths, the internal temperature of the Dan furnace rose to the temperature required for the refining of the Hui Li Dan.

Quickly opened the lid of the tripod, and the divine mind controlled more than a dozen jade bottles to open, and each poured out different amounts into the Dan furnace, and closed the lid of the tripod.

The mind controls the different medicinal liquids, forming a large liquid mass. The spiritual power was like silk wrapped around the liquid mass, and it quickly hit the Dan Duel, the temperature increased by one layer, and the liquid mass suddenly divided into the same twelve parts.

After the temperature was lowered by one layer, he raised his hand to make a pill decision, and the spiritual power output spread to the bottom of the pill furnace to wrap the twelve parts of the mixed medicinal liquid.

After more than twenty breaths, the spiritual power was suddenly retracted, and the Dan Dan was decided, only to hear the slight impact sound of the Dan furnace. After two breaths, the flame was withdrawn, the lid was opened, and with a sharp pull, the nine pills were received into the four prepared jade bottles.

"Hey, there is one that is much worse in quality, only a lower grade, four medium grades, and only three are top grades. Well, it should be because the Dan furnace was not preheated just now, and I will test how long the Dan furnace temperature needs to be preheated later, which should affect the quality of the Dan medicine. Zhao Xuan was a little dissatisfied and continued with his head buried in his head.

……

Half a year later, he was still in the alchemy room.

Zhao Xuan repeated the action again. A clear water was over, and the Dan furnace cooled down quickly, and the furnace was also cleaned.

The Qilin Fire was under the Xuanyuan Divine Furnace, emitting purple-red flames. After more than a dozen breaths, bottles of liquid medicine, under the control of divine consciousness, entered the Dan furnace.

The hands are constantly changing, and one by one, the handprints of the gods and Buddhas flow into the Dan furnace after mixing the vitality of the hands. In less than half an hour, a furnace of twelve pills was freshly baked. There are no lower grades, six medium grades and six upper grades, but there are no superbs.

"After refining this furnace into liquid pills, you can stop it. You can only obtain a high-level spirit beast tongue fetus, and you can start the Red Soul Pill. Hey...... Chen Ming, you wait for the master. ”

After a year of almost non-stop alchemy, Zhao Xuan's divine soul power not only recovered to its peak, but also went further, reaching the level of the Great Perfection of the Liquid Realm.

Xiuwei has already encountered a bottleneck, and it was already rare to make an inch of progress three months ago, and it has reached the threshold of breakthrough.
