Hearing the inheritance of thousands of years, Liu Zhendong was a little unconvinced, and said: "It's impossible, this Dan furnace doesn't look like an old object, if you want to say that it is hundreds of years, I can barely believe it, it is obviously impossible for thousands of years." ”

Luo Li said: "This is the Dan furnace for thousands of years! Many ancient books have recorded it, by the way, you haven't read much ancient books about pills, so you don't know much about it." ”

Looking at the Dan furnace in front of him, Liu Zhendong still couldn't believe it, this thing has a history of thousands of years, and it is clear that the gilt or gems on it look lifelike, without any traces of time.

Soon the level 4 pill was baked, after opening the pill furnace, a few small pills were lying in the center of the pill furnace, Liu Zhendong stretched out his hand to absorb it, looked at it, and said: "It's okay, the quality of the 2nd grade." ”

Luo Li stretched out her hand to ask for it, peeled it open and looked at it, and said: "It's still the same as before, the pill you refine is of two grades, the closer you get to the inside, the better, and the more outside, the worse it is." ”

After putting down the pill, Luo Li said: "But your technique is too bad, the difficulty of refining the pill this time is not great, and the medicinal materials used are all high-quality, with the addition of such a high-quality pill furnace, you have only refined the quality of the second grade, which is really disappointing." ”

The corners of Liu Zhendong's mouth twitched, and he said: "The 2nd grade is already very good, how can there be a 1st grade every time, and you look at this elixir, only a few layers on the periphery are 2nd grade, and the inner core is all 1st grade, and there is even a little bit of super grade." ”

Luo Li still shook her head and said: "No, if it's a level 6 pill, I won't say more, this is just level 4, it's hard to satisfy me with such a performance, and it can even be said that it makes me quite disappointed, Liu Zhendong, you put too much energy on women, it's not good." ”

Liu Zhendong was not convinced, and said: "You said that I put my time on cultivation, I very much agree with this, if you want to say that it is put on women, this is complete nonsense." ”

Lori muttered, "Really, what's the deal with that medicine?"

Liu Zhendong squinted his eyes and said, "What kind of medicine, what are you muttering, can you say it out loud!"

Luo Li hurriedly changed her words and said, "It's okay, I'll just ask you if you can refine a level 7 high-grade elixir." ”

In terms of high-grade pills, Liu Zhendong knew very few pills, and the success rate of refining was miserable.

Liu Zhendong thought for a moment and said, "Level 7 pills, barely able to refine. ”

Luo Li opened a beautiful crate and said, "Then let's refine some simple level 7 pills, such as the Tiger Bone Deer Blood Pill." ”

Liu Zhendong sighed and said, "I don't even know this prescription, I just know what the approximate effect is." ”

Luo Li took out the medicinal herbs and said, "It doesn't matter, I will! Come, I'll tell you, remember carefully." ”

Tiger Bone Deer Blood Pill is a level 7 pill, naturally not as simple as Luo Li said, its medicinal effect is very domineering, it can greatly restore the spirit and spirit in a short period of time, which is why it is called a high-level pill, this is the reason why it is called a high-level pill, if it is in the middle of the battle, knocking down such an elixir, it can instantly recover the consumption, and it can continue to speed up the recovery speed, in the same way, according to the different focuses of the eight monks, the proportion of medicinal materials blended is not very different, among which the best blend is the monk of the Spirit Sect, because it is the main cultivation of the spirit, and the recovery of the spirit is also the easiest, so the difficulty is the lowest, although it is a level 7 pill, the difficulty of refining is not high, Roughly similar to the level 6 pill, the most difficult thing is the formula of the Divine Sect, because the medicinal materials of the Divine Soul are very expensive, and the recovery of the Divine Soul is quite difficult, so the difficulty of refining the Divine Sect has been directly increased to the level 8 category.

Luo Li's so-called Tiger Bone Deer Blood Pill is a level 7 difficulty of the Eight Classics, a pill that specializes in restoring Qi Sect monks, and the medicinal materials of innate qi are also very precious, but they are far lower than the Divine Soul medicinal materials, and the difficulty of refining is also slightly lower, so it is rated as a level 7 high-grade pill.

The elixir of the Level 6 Essence Sect is called Tiger Blood Yang Spring Soup, and the elixir of the Level 8 Divine Sect is called Flying Soul San.

The first precious medicinal materials that need to be used are also the key to restoring the innate qi, which is the tiger bone of the white fronted tiger, and the legendary fairy deer grass, also known as the unicorn grass, the tiger bone is already difficult to find, mainly because the wild tiger is too rare, and it is even more difficult to find the fairy deer grass, why is it called unicorn grass, this thing is really as rare as the unicorn, the place where it appears is ethereal, there is no fixed growth environment at all, sometimes it appears next to the snow pool of the Tianshan Mountains, sometimes it appears on the Gobi rocky beach, or it appears in the cliffs, in short, it is very difficult to find。

Liu Zhendong saw the unicorn grass for the first time, it belonged to the spirit grass that looked at its unsightly appearance, and it felt very peculiar, from the perspective of external view, this seemingly ordinary grass actually contained a large amount of innate qi, and the degree of abundance was surprising, even higher than some Qi Sect monks, which can be described as a treasure of heaven and earth.

Luo Li put on special gloves, slowly took out the unicorn grass, and said: "Xianlu grass is also known as unicorn grass, and I don't need to talk more about its preciousness, so for the sake of insurance, in the practice stage, you first refine the smallest dose, and the tiger bones are actually very few. ”

Liu Zhendong also looked at the tiger bone just now, to tell the truth, the quality of the tiger bone is very high, better than the quality of the tiger bone used by Liu Zhendong before, and it is very large! This is the most precious pipa bone, which is very suitable for medicine, and the essence contained in it is also quite abundant.

In addition to these two main materials, there are some other medicinal materials, of course, these auxiliary medicinal materials are also very valuable, many medicinal materials are things that Liu Zhendong could not buy before, but he didn't expect Luo Li to bring dozens of boxes at once.

The previous medicinal materials have been purified, due to the particularity of high-grade medicinal materials, tiger bones and unicorn grass can be poured directly into the Dan furnace without purification, the so-called medicine with medicine, while proposing and fusing at the same time, there is no fixed way, all rely on the play on the spot.

This is because the spirituality of high-grade medicinal materials, if it is directly purified like ordinary medicinal materials, is too wasteful, and what is the purpose of purification, isn't it just to refine the essence and remove impurities?

And the difficulty of high-level pills lies in the improvisation, the so-called amorphous, is the biggest difficulty, the general law can be summarized and recorded in the book, there are too many changes on the spot, you must experience it yourself, in order to experience all kinds of difficulties, just like the enlightenment in cultivation, this is also the biggest threshold, ninety percent of the pill pharmacists are stuck on this layer, staying at the level of level 6 for life, and cannot step into the category of level 7.

The prescription of the tiger bone deer blood pill is not complicated, Liu Zhendong remembered it after listening to it, and Luo Li also introduced a lot of situations that he would encounter, but Liu Zhendong had a trace of hesitation when he put in the medicinal materials.

Luo Li knew what Liu Zhendong was thinking, and said: "Rest assured and bold refining, just let you put a little less, not let you not let go, what is this, the most precious of this batch of medicinal materials is still behind, I also brought a complete ginseng fruit, it depends on whether you have fate or not." ”

After hearing the word 'ginseng fruit', Liu Zhendong's eyes lit up, ginseng fruit belongs to the top medicinal materials, and it is the main medicinal material that can refine grade 9 pills, and its preciousness is rare even in ancient times, let alone in this era of scarcity of medicinal materials.

Liu Zhendong gritted his teeth and stomped his feet, and after putting on his gloves, he cut off a piece of unicorn grass, and then opened the Dan furnace and threw the unicorn grass and tiger bones into the Dan furnace.

Slowly turning on the flame switch, Liu Zhendong calmed down and released his divine soul and innate qi, watching the changes inside the Dan furnace.

At the beginning, he encountered great difficulties, the tiger bones were quite smooth to fuse, and the unicorn grass was very repulsive, and he had been constantly free from the essence of medicinal materials, and he had always refused to enter it, Liu Zhendong didn't dare to use too much force, after all, there were very few unicorn grasses put in, and if he used too much force, he would destroy the innate qi in the unicorn grass, and he could only guide it slowly.

It's a pity that the unicorn grass doesn't give Liu Zhendong a good face, and he still goes his own way, seeing that the temperature of the flame is already suitable, the tiger bone has begun to melt slowly, at this time, if you don't add the unicorn grass, the entire medicinal essence will be formed, and this refining will be regarded as a failure.

So Liu Zhendong can only take the risk, forcibly wrap the unicorn grass and bring it into the essence of the medicinal herbs, the unicorn grass is naturally very resistant, constantly struggling, the spirit does not dare to touch, can only make elastic avoidance, but the action of the unicorn grass is getting bigger and bigger, if it goes on like this, the Dan furnace will be damaged, in fact, the essence of the medicinal herbs has begun to be integrated into the molding, this refining has been regarded as a failure for more than half, but there is still a chance to make up for it, it depends on whether Liu Zhendong can surround it.

The spirit was not enough, Liu Zhendong mobilized the innate qi for counseling, and under the combination of the two, how could the unicorn grass resist, but it was also unable to twist the thighs with his arms, and could only be dragged into the essence of medicinal materials.

After entering, the unicorn grass began to calm down, following the essence of the medicinal herbs that had been fused.

This is the first step, after integration, we must also vigilantly stare at the reaction and change, and then we can shape, and finally Cheng Dan.

In the process of integration, the conflict continued, and it was suppressed by Liu Zhendong again and again, on the whole, all the medicinal materials in the Tiger Bone Deer Blood Pill were considered moderate, and there would not be too much conflict, the most difficult point was that when shaping, the essence had to be forcibly stuffed into it, and the main body was the innate qi refined by the Qilin Grass, which was the most difficult place at that time.

Sure enough, after surviving the changes in the fusion stage, the Qilin Grass in the shape began to be restless again, and the innate qi that had been refined was very excited, and began to wander desperately again, wanting to escape from the high temperature environment of the Dan Furnace.

So the two sides began to chase and intercept, Liu Zhendong relied on the total amount of divine soul and innate qi, constantly intercepting the unicorn grass, and forcibly stuffed something into it, although it was just stuffed in, it would be squeezed out by the unicorn grass immediately, but it was so hard to stop, it had to be clamped, like compression, forcibly according to the requirements of the prescription, shaped into the required arrangement.

Forcibly compressed like this, you have to die hard, naturally it is not good, shaping can also be forcibly fixed together, what to do when you become a pill, then you have to let go, otherwise, you can't always resist it, as soon as you loosen the pill, it will be scattered, how can this become a pill.

Liu Zhendong found that this was the case, as soon as he let go, the pill would be dispersed, and he could only continue to tighten, but the roasting time had exceeded the best time, and if it continued like this, the essence of the medicinal herbs would be lost due to high temperature, and it must be disposed of as soon as possible.

Luo Li estimated behind her that the time had passed, and she hadn't turned off the furnace for so long, presumably Liu Zhendong failed to refine for the first time, which was also a normal thing, Luo Li didn't feel very disappointed, after all, this was a level 7 pill, and the difficulty of refining was still relatively large.

Just as Luo Li was about to comfort Liu Zhendong with a few words, let him rest first, think about today's alchemy process, and when she continued refining tomorrow, the fire of the Dan furnace suddenly became fierce, seeing this scene, Luo Li was very surprised, this has reached the final stage, the furnace fire should be mild, how can it suddenly become violent.

Liu Zhendong didn't want to fail like this, and thought of the 'Thunder Dragon' in his body, the 'Thunder Dragon' is also the innate qi conceived by the essence of plants and trees, although after several mutations, it is essentially very different from the original appearance, but it cannot be denied that it is the body of the essence of plants and trees, so with the attitude of a dead horse as a live horse doctor, Liu Zhendong gave it a go, ready to let the 'Thunder Dragon' wrap the pill to try, whether it can successfully shape the pill.

Because the 'Thunder Dragon' has its own electrons, it is originally a violent attribute, so after wrapping the pill, the temperature in the pill furnace cannot reach the pill directly, and Liu Zhendong began to raise the temperature and increase the flame.

Not to mention that as soon as the 'Thunder Dragon' appeared, the pill immediately stopped making noise, and began to fold and form in a regular manner, and when it was about to become a pill, the mutation occurred again, and the pill was constantly tearing the 'Thunder Dragon' into it.

Liu Zhendong was puzzled, he wanted to let go of the pill, but found that it didn't seem to work, the 'Thunder Dragon' spontaneously poured into the pill, and he couldn't pull it, like an instinct, Liu Zhendong was no longer able to command the 'Thunder Dragon', so he could only say that he cut off the connection with the 'Thunder Dragon', and did not let the 'Thunder Dragon' get supplemented.

Soon the 'thunder dragon' in the Dan furnace disappeared, and after the pill was absorbed, it began to take shape slowly, but the speed was extremely slow, seeing that 3 minutes had passed, and it had not yet been closed, Liu Zhendong was a little anxious, raised his hand, and poured a large number of 'thunder dragons' into the Dan furnace. The influx of the thunder dragon, the formation speed of the pill is getting faster and faster, Liu Zhendong is not stingy, and began to input a large number of pills, in order to quickly become a pill, because the epidermis of the pill is not shiny, and it begins to become dull, this is because the delay is too long, the essence of the medicinal materials in the pill has begun to collapse, and slowly disappears.

With a crisp sound, Liu Zhendong turned off the fire, wiped the sweat on his forehead, and slowly opened the Dan furnace, only to see a black pill lying in the center of the Dan furnace.

Liu Zhendong shook his head and said, "I didn't expect it to fail, refining a waste pill." ”

Luo Li frowned and walked to the Dan furnace, and said: "I can't blame you, this time the refining time is too long, it is estimated that the essence of the medicinal materials has been lost and collapsed, which caused the waste of the Dan, but I have finally completed the last step, Cheng Dan is a success, take a break today, go back and think about the situation, make a detailed summary, and continue to refine the Dan tomorrow." ”

Liu Zhendong nodded, reached out and grabbed the pill, and was about to throw it into the waste bucket when he paused, spread out his hand and looked at the pill and frowned.

Luo Li also found out that something was wrong, because the waste pill that had no spirit began to slowly overflow a trace of innate qi, although it was very weak, but it did exist, strictly speaking, this pill did not belong to the waste pill.

As the name suggests, the waste pill has no value, and naturally there will be no so-called spirit and spirit, just like the 'dead thing', not only does it not have any benefit from taking the waste pill, but it is a basket of disadvantages, so it can only be discarded.

Luo Li looked at Liu Zhendong and said, "Otherwise, cut it open and take a look." ”

Liu Zhendong nodded, took out the jade knife and peeled off the pill directly, and the result was that the cut pill was the same on the inside and out, just like the pill skin, it was all black and dark.

Luo Li was very puzzled when she saw this scene, and said, "Could it be that it is a 7-level 9-grade pill?"

Liu Zhendong was a little unsure, because after the incision of the elixir, there was still only a trace of innate qi, and it did not increase or weaken.

Swinging the jade knife again and cutting it into a complete one-eighth size, Liu Zhendong picked up a small ball and said, "I'll know if I try it." ”

After taking the pill, Liu Zhendong was full of shock, Luo Li looked at Liu Zhendong's expression and asked, "What's wrong?"

Liu Zhendong pointed to the pill and said, "You take one and taste it, and you'll know." ”

Luo Li picked up a small piece and put it in her mouth, the bitter taste filled the entire mouth, but the pill melted in the mouth, but it was very in line with the standard of the elixir, after entering the body, Luo Li felt a strong warm current appear, not only the innate qi, but also the spirit and the soul have recovered a large section, the most terrible innate qi, continuous strong recovery, you must know that this is one-eighth of the size! The effect of the medicine is only one-eighth of the whole, if you take it whole, the recovery effect is quite terrible! At least far beyond the level 7 elixir Tiger Bone Deer Blood Pill, you must know that the Tiger Bone Deer Blood Pill can only restore the innate qi to a large extent, restore the spirit with a medium range, and restore the soul with a small extent.

And the elixir refined by Liu Zhendong restored the innate qi in a huge amount, greatly restored the spirit, and moderately restored the soul.

Don't underestimate the effect of restoring the divine soul, it is already comparable to the level 8 flying soul scattering, and the recovery of the divine soul is the most difficult, even if it grows from a small to medium amplitude, it is a huge leap.
