In the vast hall, dozens of Immortal Realm monks were concentrating, engrossed, and diligent...... Refining medicine. And in the light gate above the main hall, from time to time there are immortal realm monks who have just arrived here through the first level, and in a short time, the number of immortal realm monks in the main hall has increased from the original dozens to hundreds, and with the passage of time, the number of people entering this hall continues to increase.

Like Xia Mu, the vast majority of the Immortal Realm cultivators who came to this hall had almost never or rarely come into contact with alchemy, and the level of alchemy was completely disproportionate to their cultivation, so the Immortal Realm cultivators who came to this hall were all diligently learning how to refine medicine at the moment.

And Xia Mu, as the first person to arrive at this hall, although the speed was very fast, it was useless, in the end, he still had to learn how to refine medicine little by little.

Shen Nian slowly withdrew from a jade slip that recorded the experience of refining medicine, Xia Mu glanced around, but found that it seemed that everyone got a different prescription, but except for this difference, the other conditions were the same, and there were only three chances.

"It seems that the elixir I want to refine should be the highest grade at the moment. With a muttering in his heart, Xia Mu glanced at Bai Guan who was explaining to the new immortal realm monk behind him, and then shook his head helplessly, and once again turned his gaze to the stone platform in front of him.

On the stone platform, there are three kinds of medicinal materials needed to refine the Tianling Pill neatly, in addition, there is also a Danding that has reached the first grade of the world, and there is nothing else, that is to say, this assessment is not limited to the method of refining the pill, as long as the pill can be refined.

Sweeping the things on the stone platform with a rough glance, Xia Mu waved his palm, put away the three medicinal materials for refining the Heavenly Spirit Pill, and then took out the low-grade medicinal materials from the Qiankun Ring, with his current alchemy technique, it is simply impossible to successfully refine the Heavenly Spirit Pill, so Xia Mu needs to learn alchemy by refining low-grade pills, and when he is sure enough, he will consider starting to try to refine the Heavenly Spirit Pill, after all, there are only three parts of the medicinal materials, if all of them are exhausted and the refining has not been successful, it will be regarded as a failure.

Since he knew almost nothing about alchemy, Xia Mu did not start refining medicine immediately at first, but looked through all the classics on alchemy that he had collected in the past, and after reading through it and memorizing it by heart, he began to try to refine some low-level pills.

At this time, it has been nearly half a day since he entered this hall, and during this period, there have been some immortal realm cultivators who are proficient in the Dan Dao who have refined the elixir specified in the Dan Fang and successfully passed this level, but these have nothing to do with Xia Mu, because he has opened the enchantment at this moment, isolating the platform he is on from the outside world, preventing others from disturbing him when refining the medicine.

Carefully picking up the elixirs on the platform, Xia Mu identified the medicinal age of these medicinal materials one by one according to the "method of observing medicine" recorded in the classics, and selected the medicinal materials of the appropriate age.

If the medicinal properties are unbalanced, the pill will easily explode in the process of refining, and if it is serious, it may even blow up the person refining the pill directly, so choosing the right age of medicinal materials for refining is the common sense that every alchemist must understand.

Of course, when the alchemy attainment reaches a certain level, it is possible to improve the prescription to a certain extent and refine a better quality pill, but that is not what Xia Mu is worried about, he only hopes to be able to refine the Heavenly Spirit Pill smoothly now, as for how to improve the quality, that is something that will be considered when he has time in the future.

After preparing the medicinal materials, Xia Mu officially began refining the medicine.

"Replenish the elixir, a Lingru grass, a drop of spiritual chalcedony, and two ...... cypress flowers"

Xia Mu squinted his eyes slightly, reviewed the medicinal materials needed to refine the spirit tonic pill in his mind, and then opened his mouth to spit out wisps of blue flame at the medicine tripod in front of him.

As soon as his palm grabbed on the platform, a pale green Lingru grass was grabbed by Xia Mu, and after a little hesitation, he threw it into the medicine tripod.

As soon as the Lingru grass was thrown into the medicine tripod, before Xia Mu had time to control the fire, the blue flame rose up, and in the blink of an eye, a Lingru grass turned into pitch-black ashes, and was finally expelled from the tripod by the prohibition in the medicine tripod.

"This ......" Looking at the Lingrucao that had been burned to ashes because of his mistake, Xia Mu was so embarrassed that he couldn't speak for a while.

"Go on, anyway, how many of these low-level spirit grasses are enough, it's completely enough for me to accumulate experience. Xia Mu first muttered to himself, and then threw a Lingru grass into the medicine tripod again.

This time, Xia Mu deliberately controlled the fire, but Lingrucao only held on to the medicine tripod for a while, and in the end, he still couldn't escape the fate of turning into ashes.

"What's wrong with this time?"

Xia Mu looked at the ashes of the medicinal materials discharged by the medicine tripod speechlessly, he had made frequent mistakes at the beginning, so how long would it take for him to improve the alchemy technique to the level where he could refine the Heavenly Spirit Pill?

Shaking his head, Xia Mu didn't think about this terrible question for the time being, but continued to throw Lingrue grass into the medicine ding. Finally...... After burning more than forty Lingrue grasses, Xia Mu barely mastered the temperature requirements of Lingrue grass, and successfully refined a drop of pale cyan juice, and then this juice was refined under the blue flame, and the water in it evaporated, leaving a little bit of pale green powder, which was the essence of the medicinal power in Lingrucao, and after Xia Mu burned more than forty Lingrucao grasses at any cost, it was finally refined by him.

Looking at the pale green powder in the medicine ding, Xia Mu couldn't help but breathe a sigh of relief in his heart, but as a result, this mood fluctuated, causing him to temporarily lose control of the blue flame, and the next moment, the original pale green powder was incinerated into pitch-black ashes in front of Xia Mu's eyes.

"I@#¥%......" Xia Mu almost couldn't help squirting out a mouthful of old blood, seeing that he was about to succeed, but he fell short at the last moment, which really made him even have the heart to scold his mother.

However, being angry is angry, the medicinal materials that should be refined still have to be refined honestly, and after calming down a little, Xia Mu began to refine the Lingru grass again, and this time nothing else happened, allowing him to smoothly refine a little light green powder.

Next, Xia Mu concocted the same method, and refined dozens of Lingru grass one after another, successfully refining a small pinch of pale green powder.

"Okay, this amount should be enough to refine the elixir dozens of times. Looking at the pale green powder that was placed in the jade plate, Xia Mu smiled slightly, then grabbed another medicinal herb on the stone platform and began to continue refining the essence in it.

With the previous experience of refining Lingru Grass, Xia Mu was obviously much easier to refine the Bai Kui flower this time, just burning a dozen Bai Kui flowers, and successfully extracting the essence of it.

What is extracted from the Bai Kui flower is a kind of tiny grains with a slight bluish tinge, these grains contain a large amount of concentrated spiritual power, and if you take it directly, you can also supplement the spiritual power in the monk's body to a certain extent, but it is not as cost-effective as using it to refine the elixir.

As for the spirit chalcedony, it does not need to be refined, and can be directly used to refine the spirit tonic pill.

Looking at the essence of medicinal materials left behind after refining on the stone platform, Xia Mu nodded slightly and muttered: "Refining medicinal materials is nothing, the next refining pill is the main event, I hope it won't fail too many times." ”

By now, Xia Mu no longer had the luxury of hoping to be able to refine it at one time, as long as he didn't fail too many times, he would be thankful.

Taking a deep breath, Xia Mu once again reviewed in his mind the steps of refining the spirit tonic pill and the matters that needed attention, and after a while, he began to put the light green powder refined from the spirit grass into the medicine pod, and smoked it with blue flame for nearly half a column of incense, and after the light green powder melted slightly, he quickly put the grains extracted from the Bai Kui flower into it.

As soon as the light blue grains entered the medicine tripod, they were wrapped in the slightly melted light green powder controlled by Xia Mu with his divine thoughts, like a sugar coating, and gradually merged into one under the smoke of the blue flame.

Shen Nian carefully observed the degree of fusion of the two medicinal materials in the medicine tripod, and every once in a while, Xia Mu would drop a small drop of spirit chalcedony into the medicine tripod.

After the spirit chalcedony entered the medicine pod, nothing changed, but it slowly penetrated into the powder and grains, harmonizing the balance between the two.

"The degree of temperature requirements for various medicinal materials is different, and the same medicinal material, over time, needs to be refined with different degrees of flames, but I didn't expect that just refining a pill in the world will divide the divine mind for multi-thought control. Looking at the pill that was gradually taking shape in the medicine tripod, Xia Mu's expression was slightly solemn, although he didn't expect to be able to refine the tonic pill at one time, but if it was really refined, it would naturally be a very happy thing.

However, the wish is very beautiful, but the reality is very cruel, when Xia Mu tried to control the change in the temperature of the blue flame in the medicine tripod, he only heard a soft sound of "bang", and the pill that was about to take shape burst open instantly, fortunately, this is only an incomplete pill of the world after tomorrow, so even if it exploded, it was completely borne by the medicine tripod, but it did not affect Xia Mu.

"Well, I knew it wouldn't go so well. Shaking his head, Xia Mu re-put the essence of the medicinal materials for refining the tonic elixir into the medicine tripod and started refining the tonic elixir again.

And in this process, in other places in the hall, there is also a continuous phenomenon of pill explosion furnaces, and those who can really successfully refine the designated pill are not one out of ten, which shows that although there is no gunpowder smoke and no blood in this level, for the vast majority of people, its difficulty is still above the first level.

Fortunately, this level only requires refining the pill specified in the pill, and there is no time limit, so you can stay as long as you want.

Time passed little by little in the process of refining the medicine that everyone was crying for.
