Through Mu Yuanli's slow exploration, Chen Xuan found the difference between these two identical elixirs, which is also a necessary thing for an alchemist, that is, to recognize the elixir, if you want to become a top-level alchemist, you need to have the ability to recognize the elixir.

"Great, I didn't expect you to be able to identify the difference between the elixirs, then the chances of our refining success will also be greatly increased, then let's distinguish these elixirs now and distinguish the first-level elixirs!" said the hall master of the Dan Hall with an excited tone on his face.

Soon, Chen Xuan used all the elixirs to identify and change with Mu Yuanli, and separated those with intermittent spiritual energy, the first-level elixir only accounted for a small part, and the traumatized elixir still accounted for the vast majority, which was also why Chen Xuan did not pay attention when picking the elixir, maybe it hurt the origin of the elixir.

"Since they are all differentiated, let's start now, when I am alchemy, you first familiarize yourself with the basic requirements of alchemy!" After speaking, the hall master of the Dan Hall handed Chen Xuan a booklet.

"This is my experience in alchemy over the years, you can take a look, if you are interested, you might as well try alchemy, and it will not delay the time to cultivate, it mainly depends on whether you have talent, if you have good talent, you can become a qualified alchemist in a few years!" The hall master of the Dan Hall took out a yellowed pamphlet and said.

After taking the booklet handed over by the hall master, Chen Xuan knew in his heart that the hall master of this Dan Hall also seemed to have the potential of Mu Yuanli, and once he was keen on alchemy, he would probably be able to vigorously woo himself at that time.

"Then thank you hall master!" Chen Xuan picked up the booklet and began to study it, while the hall master of the Dan Hall began to prepare for alchemy.

A flame rose up, and the fire that was still very small under the Dan furnace just now suddenly became vigorous, and the heat of the entire Dan room quickly increased, and the heat instantly filled the entire stone room, and the flames were like a spitting tongue of fire, spitting endlessly, and a crackling sound soon came from the inside of the Dan furnace.

Chen Xuan closed the booklet in his hand and watched the procedure of refining medicine in the Dantang Hall, the booklet Chen Xuan could remember all the steps in his mind in a few breaths, and Chen Xuan basically mastered the steps of refining medicine recorded in it, but how to refine it was a practical problem, now that the theory is there, what Chen Xuan lacks is the actual operation.

The Dan furnace was roasted and yellowed by the hot flames, and the steaming heat began to emerge from it, and the hall master of the Dan Hall instantly took out an elixir and put it in, and then his body began to wander around the Dan furnace, and his hands made Taoist palm prints, and hit them towards the Dan furnace, without any sound, and all these palm prints were submerged into the Dan furnace.

Chen Xuan knew this technique that this was refining, and by manipulating the elixir inside, the impurities of the elixir were eliminated.

Any elixir will have impurities, alchemy is to drive out the impurities in it, and retain the essence inside, the first thing alchemy to do is to drive away impurities, this is a very complicated work, the elixir will soon be roasted dry in the hot Dan furnace, that is to say, in a short breath of time to remove all the impurities of the elixir, otherwise once the elixir is all dry and becomes a powder, even if you are using thousands of techniques, you can not improve the quality of the elixir.

The tongue of fire is spraying, the temperature of the Dan furnace is not rising to a certain extent, Chen Xuan also glanced at this Dan furnace when he came in, but Chen Xuan had no way to tell the good and bad of the Dan furnace, but he could see the carved ancient words from the top of this Dan furnace, it seems that the age of this Dan furnace is definitely very old, and it can also release a faint aura fluctuation inside, and some unknown formations began to start slowly on the top of the Dan furnace.

One after another, the elixir was injected into by the hall master with excellent techniques, and impurities were constantly decomposed out, although Chen Xuan was still a layman at this time, he could also feel the changes in the elixir, and all the remaining essence was kept in the Dan furnace.

Soon, dozens of elixirs were all submerged into the Dan Furnace, at this time, the hall master's technique changed one after another, becoming slow, Chen Xuan from the hall master's body style, it seemed that his posture of playing Tai Chi in his previous life was a bit similar, and the elixir that had been dissolved in the Dan furnace slowly moved in with the hall master's body.

Chen Xuan, who was standing in the distance, did not let go of any change in the details, and then the second elixir went in again, and it was the same technique again, but this time the speed was not as fast as the first time, Chen Xuan knew that the elixir with the most impurities was generally placed in the front to refine, and the higher the level of the elixir, the fewer impurities would naturally be, and it would naturally be placed at the end.

The time of a stick of incense passed, and all the elixirs for refining the pure elixir were beaten into the Dan furnace by the hall master, and suddenly the top cover of a Dan furnace the size of a water tank flew up, directly covering the top of the Dan furnace, and then I saw that the formation on the Dan furnace began to start, and the flames jumped up all of a sudden, and the hall master also retreated to the side.

"Can you see the key to this?" asked the hall master of the Dan Hall towards Chen Xuan.

"Forgive me for being stupid, it's hard to see the essence of it!"

"It doesn't matter, as long as you want to learn, I will teach it, you don't have to be burdened, as long as you have time to come over, alchemy is not about teaching you, it mainly depends on your talent for alchemy!"

"Then the juniors will thank the seniors, and if there is a chance, the juniors will definitely want to ask the hall master for advice!"

"Then I'll tell you a few steps of alchemy now, first, purification, this is the most basic kung fu of alchemy, a lot of elixir waste is in the place of purification, time, heat, must be controlled very well, a mistake, the elixir will be scrapped, you can slowly familiarize yourself with this in the future!"

"In, fusion, this is a more esoteric thing, not words can be learned, but to rely on your own continuous research, now what I want to do is fusion, slowly fuse these four or five kinds of elixir together, even if your elixir is very pure, but can not be fused, it is also a pair of fly ash, there is no effect, this level is also crucial!"

Chen Xuan listened intently, not letting go of any detail.

"The last one, and the most critical one, molding, this is also the most difficult place in alchemy, many alchemists can not only disperse the impurities of the elixir, but also fuse these elixirs together, but the last step, forming, does stop a lot of alchemists from moving forward, the higher the level of the elixir, it is difficult to fuse, and the formation is even more difficult, which requires the alchemist to constantly think about every change in the Dan furnace, because every change can be related to whether your furnace pill can be formed!"

"If you learn these three points, then you are also a qualified alchemist, but it is also very difficult to achieve this requirement, which requires you to explore a lot, that is to say, you need to refine a lot of pills and find out the key to it!"

"Thank you for the teachings of the seniors, the juniors understand!"

"As long as the pill is formed, the rest of the matter is much simpler, that is, to collect the medicine, and you should not underestimate [receiving the medicine] This process, the pill is a regular shape when it is formed, during this period, you need how to collect the medicine, the pill refining out of light and smooth, the key to this also needs to be mastered by yourself, and finally it is out of the oven, the baking is also very critical, not early, nor late, the medicinal properties of the pill are not enough, it has lost a lot of effect, slow, maybe the medicinal properties of the pill will disappear, and even become a waste pill, how to refer to it I have an introduction, as long as you can understand the meaning of it, you understand!" The hall master of Dantang took the trouble to explain.

"Thank you for the guidance of the seniors, the juniors are grateful!"

"This time the elixir has been refined, you might as well come and try it when you have time, there are also a lot of pills here, you can refine some ground-level pills first, don't be afraid of wasting the elixir, we have it here!"

"Hall Master, what do you mean by the need for fire element power to refine the pill just now, it will be better!" Chen Xuan asked.

"You can't touch this for the time being, we are now refining the pill with the fire of the heart of the heart called the alchemist, and there is a more advanced alchemist above the alchemist, that is the [Danzun], every [Danzun] can control the power of the flame, without the fire of the heart, relying on the Tao of their own comprehension, plus absorbing the power of fire, using the power of fire to refine the pill, whether it is the speed or the probability of success, it is much higher than the ordinary level of alchemy!"
