The two kept communicating, and the hall master of the Dan Hall also explained to Chen Xuan what pills these elixirs could refine one by one, what pills had medicinal properties, and what elixirs were needed to explain to Chen Xuan, Chen Xuan was also listening, and every detail was very serious and stopped, although it was impossible for him to spare a lot of time to learn alchemy, but it was no harm to know some knowledge.

"Hall Master, tell me what the function of this pure spirit pill is!" Chen Xuan asked.

"Pure elixir, as the name suggests, is an elixir containing pure aura, this elixir can help people recover their Yuan Force, but to help their own lack of vitality when breaking through, especially when breaking through the lack of aura, the value of this pure elixir will be reflected, some disciples do not have a lot of Creation Pill, this Pure Spirit Pill has played a huge role, and the pure spirit pill does not need any refining, its value far exceeds the value of the Creation Pill, a pure spirit pill can be worth 500,000 Creation Pill!"

"I see, if I break through, I will be able to take this pure elixir!"

"There is also this Great Returning Pill, this is an elixir for treating injuries, and it has the same effect as the [Qiankun Recreation Pill], but the value of the Great Returning Pill is far more than the Qiankun Recreation Pill, as long as there is still a breath, it can basically recover quickly, as long as it is not cut off from life, it can be saved, each of this Great Returning Pills is very rare, and it is basically difficult to buy it outside!" After speaking, the face of the hall master of the Dan Hall showed a trace of envy.

"What is the role of the Yin Yang Glazed Pill!" Chen Xuan continued to ask.

"You're on point, although the first two kinds of pills are scarce, as long as you have the elixir, you can basically exchange it, and you can even buy it with the pill, but this Yin Yang Glazed Pill may not be able to buy it no matter how much resources you spend!"

"Please make it clear!"

"The main effect of the Yin Yang Glazed Pill is to help people improve their strength, especially your current realm, as long as you take a Yin Yang Glazed Pill, you can immediately break through the early stage of Yuanwu and reach the middle stage of Yuanwu, and the acquired martial artist, as long as you take one, you can immediately break through the acquired Lingwu Realm, so that the road of cultivation in the future is open, these pills are very precious in the Earth Spirit Realm, but the Yin Yang Glazed Pill cannot improve the strength of the Earth Spirit Realm to the Heavenly Spirit Realm, this threshold is not a pill that can be solved, but the Yuan Wu Realm wants to break through the Earth Spirit Realm, and your Yin Yang Glazed Pill can increase the chance of three percent!" said the hall master of the Dan Hall with an excited tone.

Chen Xuan showed an excited smile on his face when he heard this, except for the last [Yin Yang Glazed Pill] of these pills that can impress him, the other pills have no impact on himself, the pure spirit pill has a Heaven Swallowing Furnace on his body, as long as the Creation Pill is transformed by the Heaven Swallowing Furnace, it can provide pure aura, and the Great Return Pill, he has a soul stone on his body, and his soul stone can recover any injury, which is not very valuable to Chen Xuan.

Chen Xuan's idea would not be angry if the hall master of the Dan Hall knew about it, not everyone was as anti-heaven as Chen Xuan, there were two things on his body, the Heaven Swallowing Furnace and the Soul Stone, they were all hard work and needed to refine and purify by themselves, the pure spirit pill could reduce the refining time of many people, and the purity was thousands of times better.

And the Great Returning Pill is the second life of a cultivator, and no one will take out such an elixir to sell it, so the value of the Great Returning Pill is also very rare, but after having the soul stone, Chen Xuan naturally looks at these things a lot lighter.

"I have already told you the types of pills, the next step is refining, I estimate that these pills will take half a month at the earliest, we are here during this time, and don't have any distractions, once there is a mistake, all the elixirs will be scrapped, and this [Yin Yang Glazed Pill] This is my first refining, so I can't guarantee whether it can be refined, I only look at it from the Danfang, so this time the risk of our refining is also very great, Chen Xuan, have you thought about it, really all refining?" The hall master of Dantang asked.

Chen Xuan glanced at the other party and nodded firmly, although the elixir is precious, if it is really refined, it will really lose a lot of elixir, in fact, Chen Xuan understands very well that if the Danxuan Gate Dantang Hall Master in the Northern Regions cannot refine the elixir, even if he gets it to other places, he may not be able to refine it, so Chen Xuan has no objection and directly agrees to refine it.

"Okay, let's start now, you are responsible for giving me a hand, and you will also have to input the Yuan Force to the Dan Furnace at a critical moment, I will instruct you at that time, if only you could control the Fire Yuan Force and the Mu Yuan Force, then it will be much easier for us to refine!" The hall master of the Dan Hall seemed to be telling himself, and it was also like saying it to Chen Xuan.

"Hall Master, why does alchemy need fire yuan power and wood yuan power!" Chen Xuan asked puzzled.

The hall master of the Dan Hall said slowly while sorting out the elixir in his hand, "The fire element power that understands is the control of the flame, so that when you are refining, you can feel every change of the flame, and those who know the wood element force can be familiar with the feelings of every part of the elixir, so that the perception of the elixir will be superhuman!" Many people who refine the pill basically know how to simply control the fire element power, and they will look for some fire power to come back and refine it, but people who know the wood element force rarely like to have alchemy, even if they do, they can't refine a good pill if they don't understand the control of the fire element force, so the combination of the two is very rare!"

"How to distinguish the elixir of Mu Yuanli that the hall master said, the juniors know a little bit about the control of Mu Yuanli, the hall master might as well point out the juniors!"

"Really!" the hall master's eyes lit up.

Chen Xuan nodded.

"This is the basic way to distinguish the elixir, the above introduces the rating of the elixir, as long as you are familiar with the knowledge inside, you can distinguish the quality of the elixir, as well as the composition of the elixir, although they are all elixirs of ten thousand years, but not every elixir is suitable for refining the same elixir, this is the need for Mu Yuanli to infiltrate the elixir to feel the difference between each elixir!" After speaking, the hall master of the Dantang handed Chen Xuan a booklet.

Chen Xuan took the book handed over, carefully looked at every sentence in it, and was very serious, with the help of a huge soul power, Chen Xuan memorized all the contents of the book in the time of a stick of incense, and then returned the booklet to the hall master of Dantang again.

"Since you know Mu Yuanli, then you try it now, what is the difference between these elixirs, you first see what is the difference between these two strains, these two strains are the same year and type, whether there is a difference between them depends on you to watch and distinguish!" The hall master of the Dan Hall took out two identical elixirs and put them in front of Chen Xuan.

Chen Xuan picked up one of the elixirs, and the Mu Yuan Force in the dantian slowly mobilized, along his arm, and slowly flowed into this elixir, after the elixir absorbed Chen Xuan's Mu Yuan Force, it suddenly became more aura, because Mu Yuan Force can nourish all things, and this elixir is of course no exception.

Chen Xuan's divine consciousness also entered the elixir with Yuan Li, slowly feeling the changes in the elixir, according to his understanding of the elixir just now, this elixir should belong to the second-level elixir, that is to say, the second level of the same elixir is not ranked first, but the specific difference Chen Xuan does not know, he can only rely on the introduction in the book just now to determine the level of the elixir.

Putting down the strain in his hand, Chen Xuan picked up the elixir of the other strain again, or the same operation, Chen Xuan immediately judged that this strain was a first-level elixir, because Chen Xuan saw that this elixir was not damaged in any way, although from the outside, the elixir of the two strains was exactly the same, there was no difference, but with Mu Yuanli's feelings, Chen Xuan could feel from the top of the first strain that Nazhu had been traumatized, and there were loopholes in the elixir, maybe it was blown down by the fang wind, maybe it was broken or something, but Chen Xuan couldn't tell it。

"Can you tell me about it?"

When Chen Xuan was putting down the two elixirs, the hall master of the Dan Hall hurriedly asked.

"There is a difference, but the younger generation can't say clearly, I just feel that the aura circulating in the elixir of the first strain is not slack, there is always a feeling of unsmoothness, the elixir aura of the second strain does not have any leakage, and the aura circulates very regularly!" Chen Xuan said everything he knew.

As soon as Chen Xuan's voice fell, the eyes of the hall master of the Dan Hall lit up.
