Claire left her son, and after Clark 'learned' from Thunder Thunder, he happily said goodbye to Thunder Thunder and left. In the few days since Claire left, Clark, who worships Lei Xiaotian as his teacher, has always been very well-behaved, and he has been acting as Lei Xiaotian's apprentice every day, and he has been naturally giving Lei Xiaotian a disciple in the past few days, without any reluctance, which makes Lei Xiaotian a little impressed.

And in the next few days, there were many guests who came to the place where Lei Xiaotian lived, all of whom came to be close to Lei Xiaotian, and they all brought some gifts, I don't know why, maybe it was because of Lei Xiaotian's identity as an alchemist! The things that these people came to give to Lei Xiaotian turned out to be some medicinal materials, of course, they were all some common medicinal materials, and there were not many precious and precious medicinal materials.

However, with these medicinal materials sent by these people, if Lei Xiaotian only refined the Pure Heart Pill, the Duplicate Pill, and the Soul Rejuvenation Pill, it would be more than enough, and he could even practice more than a dozen furnaces of these three pills each.

Of course, as for the prescriptions of the five kinds of pills that Lei Xiaotian newly obtained, Lei Xiaotian has also seen them, although he has not yet started refining, but the medicinal materials required for these kinds of pills, Lei Xiaotian already knows it.

And Lei Xiaotian checked the gifts he had gotten, and found that among these medicinal materials, there were relatively complete varieties, except for the eight-grade pill Bailing Golden Pill that Claire gave to Lei Xiaotian, and there were three more precious medicinal materials, and all the medicinal materials needed to refine all the other pills were gathered.

With the passage of time, the courtyard where Lei Xiaotian lived finally calmed down, but Lei Xiaotian's mood was a little bad, the reason why Lei Xiaotian was in a bad mood now was that his cultivation was completely stuck in a bottleneck, and now in the mysteries of the laws of the light system, the fourth law mysteries of the mysteries of the light system, Lei Xiaotian had already realized the great success, but the fourth law of heaven and earth mysteries of several other laws and mysteries still had no clue.

What's more, after being unable to comprehend the mysteries of several other laws, Lei Xiaotian also tried to fuse the mysteries of the laws of the streamer technique with the first three laws of the mysteries of the laws of the light system that he had comprehended, but after cultivating for a long time, it had no effect, and the mysteries of the laws of the streamer spells could not be combined with any of the other three laws and mysteries at all, and there was a trace of fusion.

Since reaching the median god, although Lei Xiaotian has not retreated, he has been deducing the mysteries of the laws of heaven and earth in his mind, but after such a long time, whether it is comprehending the new mysteries of the laws or the integration of the mysteries of the laws, it seems that they have fallen into a bottleneck, so for Lei Xiaotian, who is very eager for strength, he is naturally in a bad mood.

And now Lei Xiaotian is living a very comfortable life, not only in the small courtyard there are a group of slaves to serve, but also Leng Ji and Gavelin two guards to help deal with affairs, and there is also Clark, an apprentice, who is casually dispatched, Lei Xiaotian naturally has a very comfortable life.

On this day, Clark saw Lei Xiaotian sitting leisurely on a chair and this small wine, but he was not in a good mood, so he stepped forward, came to Lei Xiaotian, bent down and saluted, and said: " Disciple Clark visited the master, and the disciple saw that the master seemed to have something on his mind, so he didn't dare to disturb the master, but the disciple had a problem that bothered the disciple for a long time, and my father was even because of this, he was never able to increase the refining power of the elixir, and even every time he reached this step, it was completely by luck, so the disciple's refining level always did not improve, begging the master to call me!" After finishing speaking, Clark knelt directly on one knee and bent down deeply in front of Lei Xiaotian, looking extremely respectful.

Although Lei Xiaotian is not in a good mood now, but after all, Clark is a disciple he accepted, and now that the disciple asks for advice, how can Lei Xiaotian refuse? So Lei Xiaotian smiled slightly and said: "No need to be polite, just be casual, you know how I do things, so don't be so vain, just say what you have! Although my strength is similar to yours, after all, I am your master, so what you want to ask, I will definitely tell you!" After finishing speaking, Lei Xiaotian smiled and motioned for Clark to get up.

At this time, after listening to Lei Xiaotian's words, Clarke was overjoyed, and then bowed to Lei Xiaotian again, and then slowly stood up, and then stood respectfully in front of Lei Xiaotian, and said: " Master Qiyu, that's the case, in fact, I can completely refine all the medicinal materials for refining the Liupin Pill Chongmai Dan, and I can also ensure the medicinal power of these medicinal materials, and I can also fuse these refined medicinal liquids according to the proportion, but I don't know why, I will always destroy the medicinal liquid when baking, sometimes these medicinal liquids will be directly evaporated, and sometimes I will watch these medicinal liquids finally solidify, and I can't complete the real fusion at all, and the reason why my father fails to refine medicine every time is this, so I want to ask the teacher?" After finishing speaking, Clark looked at Lei Xiaotian without blinking, looking very expectant.

After listening to Clark's question, Lei Xiaotian thought for a moment and said: "Refining medicine is actually divided into five big steps, the first is to refine medicinal materials, the second step is to remove impurities, and the third step is fusion, and after the fusion of the medicinal liquid, it is the fourth step of baking to remove impurities, and the last step is to warm up the cultivation order." In fact, this question of yours is not difficult to solve, I just want to ask, what do you think is the most important of the steps I just said? No! Maybe I ask you that you don't understand, I mean what plays the most crucial role in these steps?"

After listening to Lei Xiaotian's question, Clark thought for a long time, and then said slowly, as if lacking confidence: "The master disciple is stupid, but the disciple thinks that the most critical role in this should be the flame, after all, among the five steps of alchemy, no matter which one needs to be completed with flames, so it should be flames!" Speaking of this, Clark looked at Lei Xiaotian expectantly.

Clark replied, Lei Xiaotian glanced at Clary, and then said, "Is it a flame? Could it be that when you were administering the liquid to purify, you were directly burning the liquid with a flame?" You are thinking about it carefully, the most important thing is not the flame you said. Can I remind you, what is the main thing that the flame provides in the alchemy furnace, is it directly burned with fire?" After finishing speaking, Lei Xiaotian smiled at Clarke, who was thinking about it, and nodded at Clark as if encouraging.
