Yang Xian followed Shen Liyun to the alchemy room again, Shen Liyun began to refine the Qi Refining Pill and explained, Yang Xian listened to it like a good baby.

"The most important thing in alchemy is the control of alchemy temperature and the accurate corresponding control of alchemy techniques, this kind of control can only be achieved through continuous practice to achieve a perfect fit, the flame of the alchemy room for the teacher is guided by the ground fire through the formation, relatively stable, so the control of the temperature during alchemy is more convenient to control, which is conducive to improving the success rate of alchemy, and the Dan furnace is also a low-grade alchemy furnace magic weapon obtained for the teacher, which is also helpful to improve the success rate of alchemy.

Alchemy must first warm the Dan furnace, although this stage needs to consume aura, but it is essential, when the Dan furnace is warmed, begin to understand the spirit herb elixir used in alchemy, this step you should know, especially the year of the spirit herb elixir, medicinal properties, the dosage of the elixir and the attributes of the spirit herb elixir and the best dissolution temperature of the spirit herb elixir, these are the basis of alchemy, must be kept in mind, the next is the resistance between the attributes of the spirit herb elixir, all the attributes of the spirit herb elixir are different, There are no two herbs with the same attributes, so in the process of alchemy, you need to use your divine thoughts or keen sense to grasp the changes in the medicinal properties of the liquid and other aspects, and make adjustments in time, which requires your divine thoughts and alchemy techniques to cooperate with each other to make changes, once you grasp the best condensing nodes and receiving pill nodes, and then you can follow these nodes to cooperate with the alchemy techniques, then the success rate of this alchemy has basically reached more than 90%, which is already a high probability. It is not possible for an alchemist to achieve a 100% success rate every time in alchemy, because you can't fully control every detail, as long as any detail is not perfect, then there is a possibility of failure in every alchemy.

Alchemy is gradual, the first-order pill is 10, the second-order is 9, the third-order is 8, and the fourth-order is 7...... And so on, you just started refining the pills, although the first-order pills are ten pills after the pills, but don't pursue the success rate of the pills, because your alchemy and divine thoughts are not yet able to support you to refine the ten pills, after the ten pills are divided, give up the remaining nine pills, concentrate on refining first to ensure the success rate of one pill, when the alchemy is advanced, the ten pills will give up the remaining eight pills, and ensure the success rate of refining 2 pills... And so on, when you can control the refining of 10 pills at the same time and the output rate reaches fifty percent, that is when your alchemy can be advanced, but the difficulty of alchemy will increase exponentially with the increase of alchemy, although the success rate of alchemy will decrease with the increase of alchemy, but the time for alchemy will be saved, and it takes 1 hour to successfully refine a pill, and it is also an hour to successfully refine 5 pills or even 10 pills, which is very different. This means the loss of alchemy materials and the cost of alchemy time, after all, resources and time are precious and limited. Next, I will personally refine the pill, and you will listen to my instructions. ”

"There are 5 kinds of elixirs used in refining qi pills, the main medicine is one, condensing spirit grass, 20 years can be used, there are 4 kinds of auxiliary medicines, namely yellow essence, ginseng, fire spirit fruit and black leaf vine, the years of these elixirs are more than 20 years old, if the year is not the same, the medicinal properties are not the same, it should be noted here that these five kinds of elixirs, the year of Ning Ling Cao is 20 years, the year of Huang Jing is 25 years, the ginseng is 22 years, the fire spirit fruit is 20 years, the black leaf vine is 30 years, the year of the elixir is different, The strength of the medicine also varies. The Wenyang Dan furnace has been completed, the medicinal property analysis has also been completed, and the alchemy can begin, you first put Huang Jing into the Dan furnace. ”

Yang Xian immediately used his divine thoughts to drive the yellow essence into the Dan furnace.

"Ginseng and Fire Spirit Fruit were put in succession, followed by Ning Ling Grass and Black Leaf Vine.

Yang Xian put the remaining four elixirs into the Dan furnace in turn.

"Divine thoughts enter the Dan Furnace."

Yang Xian decisively probed half of the divine thoughts into the Dan furnace, Yang Xian found that the positions of the various spiritual grasses in the Dan furnace were different, the black leaf vine was at the top, followed by the condensing spirit grass, followed by the fire spirit fruit, ginseng, and yellow essence, although the location of the five elixirs was different, Yang Xian found that the speed at which the five elixirs melted was indeed exactly the same, and the melted elixir essence was wrapped and controlled by Shen Liyun's divine sense, and the divine consciousness and divine thoughts were very magical things, not affected by high temperatures, but they could perceive the changes in temperature.

Yang Xian's divine thought is his own eyes, Yang Xian watched silently, when half an hour later, all the spiritual herbs and elixirs were left with essence, Yang Xian's divine thoughts saw that the essence of the five elixirs was fused in turn according to the order in which the elixirs were put in, and they seemed to be very smooth, and there was no attribute reaction in the alchemy process, and the other half of Yang Xian's divine thoughts directly saw that Shen Liyun was constantly changing the alchemy technique, Yang Xian now knows, Yang Xian watched at the same time according to the situation in the alchemy furnace and the situation outside the alchemy furnace, Yang Xian felt more specific, When the liquid medicine fused, Yang Xian saw that Shen Liyun's alchemy technique had not changed, and was still in the process of fusion, and after a period of time, Yang Xian found that the liquid medicine was more mellow, at this time, Shen Liyun's alchemy technique also changed, the Dan technique was added to the Dan Condensing Technique, Yang Xian's divine consciousness stared at it tightly at the same time, Shen Liyun's divine consciousness directly and quickly divided the fused liquid into ten parts, and then ten parts of the liquid medicine condensed at the same time, it turned out that the master Shen Liyun was refining the Mandan, and the method of dividing the Dan Condensing Pill was the root of an alchemist, Different methods of dividing Dan and condensing pills have different changes in the control of the liquid medicine, and the rate of Dan formation is also different. Divide one liquid medicine into ten parts of liquid medicine evenly with the method of dividing the pill, and then directly condense the pill into the qi refining pill with the method of condensing the pill, Yang Xian felt very magical, it turned out that the qi refining pill he had taken before came from this, and the 10 pills were all pills, but Yang Xian found that there were three pills that did not seem to have the other seven pills that were smart, and finally Shen Liyun received the pill recipe, and the ten pills came out of the pill in turn, and finally found that there were 7 pills in Chengdan, and there were three waste pills, it seems that these three pills were the pills that the master Shen Liyun gave up. Yang Xian's Divine Thoughts were also withdrawn, and in the end, he found that the three Waste Pills were the three that the Divine Thoughts did not feel agile.

After Yang Xian finished reading Shen Liyun's alchemy process, he found that he was even more confused about alchemy, and he seemed to have a lot of questions to ask. Shen Liyun looked at Yang Xian with a confused look, and said at the right time: "I can answer you three questions, you ask!" ”

Yang Xian was overjoyed, so he asked the first question: "How does Master make it the same melting speed for all elixirs?" ”

"The properties of different elixirs are different, the melting temperature is different, and it is also recorded in the elixir catalog, as long as you ensure that different elixirs correspond to different melting temperatures in the Dan furnace, you can adjust the corresponding temperature of different elixirs in time."

Yang Xian thought thoughtfully, "Master, the alchemy foundation says that even if the master is a second-order alchemist, the maximum success rate of refining the first-order qi refining pill is only 6 percent, how can the master's success rate be seventy percent?" ”

"This question is a good question, the so-called success rate of alchemy, this statement is often inaccurate, because every time there are two possibilities of success and failure in refining pills, the success rate to discuss the alchemy level of alchemists is one-sided, if you want to be accurate, verify the level of alchemy of an alchemist or take the Dan rate as the judging standard, the success rate is generally said by laymen, it will be more accurate to use the Dan rate, taking the first-order pill as an example, the full pill is 10 pills, each time the alchemy is divided, after ten pills, One Dan, the Dan rate is one percent, two Dan is two, the Dan rate is two percent..... If this alchemy fails, the pill rate will be zero. Laymen say success rate, insiders say Dan rate, on the surface sometimes it seems that the meaning is similar, but it is more accurate to describe it with Dan rate. For alchemy skills, the level of alchemy rate is the most accurate evaluation of an alchemist's alchemy, if the alchemist's skills are high, it is that the number of alchemy is less, the waste of alchemy materials is less, and the alchemy rate is high, which is the standard for testing the true strength of an alchemist's alchemy.

Generally speaking, the alchemist's Dan rate can get the addition of the external Dan furnace, alchemy techniques, and experience, so the Dan rate can exceed the theoretical value, but the alchemy auxiliary bonus is also extremely limited, the refining of the Qi Refining Pill this time is because the teacher itself is extremely skilled in refining the Qi Refining Pill, and it is refining the first-order pill at the level of a second-order alchemist, and under the auxiliary bonus of the alchemy furnace at the level of the lower grade magic weapon, the Dan rate exceeds the theoretical value, reaching seventy percent, generally speaking, the sixty percent Dan rate is the most reasonable. Yang Xian suddenly became enlightened, and Yang Xian continued to ask, "Master, can alchemy avoid the appearance of waste pills?" ”

"This question is a bit greedy, but I'll tell you about it, under normal circumstances, alchemists refining pills of the same level, no matter how clever the alchemy skills are, no matter how high the success rate of the auxiliary is, such as alchemy technique assistance, good alchemy furnace assistance, etc., there will always be the possibility of failure, so it is inevitable that there will be a waste pill, but it can reduce the rate of waste pills, such as cross-level alchemy, good magic weapons to assist alchemy, etc., but Master, I have crossed the level of refining qi refining pills this time, and the maximum pill rate is only 7 percent, resulting in three waste pills, Unless I am a fifth-order alchemist to refine the first-order pill, then the ten pills of the full pill can avoid the generation of the waste pill with a high probability, and the full pill of the first-order pill can be refined, and the pill rate is 100%, and the first-order pill Mandan, refined by this super cross-level alchemy, has no meaning.

Therefore, it is inevitable that the appearance of waste pills will appear, especially the higher the level of the refined pills, the less likely it is that there will be a full pill production rate, and even the pill production rate is very low, just because there are few high-level pills, so high-level immortal cultivators are also rare, just listen to these words, there is no need to take them to heart. "The question is over, then you can go back!" "Master, I don't have a place to live here." Yang Xian said embarrassedly.
