In fact, about Jiyuan Dan, Lin Feng had only seen a record in an ancient book, but Lin Feng had been in the Source Realm for so many years, and he had never heard anyone say that someone could successfully refine it, so the refining method of Jiyuan Dan had basically been lost in the Source Realm.

It is also because of the recent cultivation of heavenly materials and earth treasures that Lin Feng has the opportunity to get the refining method of this set of Yuan Dan, because those heavenly materials and earth treasures within Huazong have also been planted for a period of time, and there are some heavenly materials and earth treasures that grow relatively quickly, which can already be picked and refined into pills, but at this time, those that can be used to refine pills are generally some branches or rhizomes of heavenly materials and earth treasures, after all, the time of the heavenly materials and earth treasures within Huazong is still a little short, so the real fruit is not ripe.

During the period of managing the cultivation of Huazong's Heavenly Materials and Earth Treasures, Lin Feng actually discovered that some of the disciples were not particularly willing to waste their time on planting these Heavenly Materials and Earth Treasures, so Lin Feng wanted to refine some pills that could help everyone to promote everyone's enthusiasm for planting Heavenly Materials and Earth Treasures, so he came to the medicine field that Liang Dong was in charge of, and picked some Heavenly Materials and Earth Treasures that could be used to refine pills.

Of course, if it was just these things, it was really impossible to refine anything, so Lin Feng came to the medicine field in the forbidden land again and selected some materials at random.

Regarding the medicinal field in the forbidden land, in fact, Zhang Yuan had already entrusted it to Lin Feng, after all, since the establishment of the sect, Zhang Yuan found that he had no time to take care of that medicinal field at all, so he could only hand it over to Lin Feng, but he asked Lin Feng that he would never be able to enter anywhere other than the medicine field.

That day, after Lin Feng picked some heavenly and earthly treasures in the forbidden medicine field, he put out all the materials he had obtained, although the heavenly materials and earthly treasures were already there, but with the heavenly materials and earthly treasures in front of him, what could be refined, Lin Feng did not have any direction in his heart, if he wanted to know what kind of pill the heavenly materials and earthly treasures in front of him could be refined into at this moment, he must first be familiar with the medicinal effects of each medicinal material, but after calculating what kind of changes would occur after combining them with other medicinal materials, how to integrate them could make this change more in line with his own hopes, Lin Feng thought that his head was big, and he couldn't calculate it, after all, Lin Feng's experience was still too littleIf you really want to invent and create a new elixir by yourself, I'm afraid you need to waste a lot of natural treasures to try, but at the moment, the materials in your hands are not allowed to do so, so you can only calculate the approximate results in your mind before you can really implement it.

Of course, even if it is calculated in one's own mind, it may not be possible to really refine the elixir in one's own calculation, after all, the medicinal effect can indeed be roughly calculated, but for the heat, it is impossible to calculate it at all, maybe the change in the medicinal effect you want requires seven points of heat, but in actual operation, the heat becomes eight points, then the elixir is absolutely impossible to succeed, so even if you calculate the direction of the medicinal effect in your heart, you need to be able to successfully refine the elixir after many attempts, so this matter is simply more difficult than ascending to the sky, not to mention Lin Feng at this momentIt is difficult to calculate even the change in the efficacy of the drug.

After calculating and not getting the change effect he wanted, Lin Feng stopped continuing to calculate, because the long-term excessive use of his brain made Lin Feng's head a little groggy, so Lin Feng could only run his true yuan first, so that his spirit could regain clarity.

Just when Lin Feng had just settled down, a slightly vicissitudes of life suddenly appeared in his mind, and this vicissitudes of life voice directly told him the refining method of Jiyuan Dan, as well as the heavenly and earthly treasures needed for Jiyuan Dan refining.

Since the voice sounded directly in Lin Feng's mind, it was as if it was directly engraved in Lin Feng's brain, even after Lin Feng woke up after a period of time, the vicissitudes of life that had just appeared in his mind were still fresh in Lin Feng's memory, and Lin Feng also discovered a strange thing, the heavenly and earthly treasures needed for the refining of the Yuan Dan happened to be all of those heavenly and earthly treasures that he had collected before, so he only needed to find some ordinary medicinal materials, and he could directly open the furnace for refining.

Lin Feng didn't understand if everything that had just happened was an illusion, but now that he knew the refining method of this elixir and the medicinal materials needed for refining, Lin Feng decided to try it directly.

When refining the pill, you need to put all your energy into it, although at the moment you are in the Huazong Cave Mansion, no one will bother you under normal circumstances, but just in case, Lin Feng still wants Xin Feizi to protect the Dharma for himself.

The refining of Jiyuan Dan took a full eleven hours, during this time, Lin Feng's spiritual power was highly concentrated, just hoping to be able to directly refine successfully, after all, the heavenly and earthly treasures in his hands at the moment were not particularly rich, and in order to increase the success rate, Lin Feng directly put the materials needed for ten Jiyuan Dan into the alchemy furnace, if this time failed, the materials in Lin Feng's hands would not be enough to refine again.

However, Lin Feng's luck was still very good, because when he was consuming the pill, Lin Feng very clearly smelled a burst of strange fragrance coming from the alchemy furnace, and the appearance of such a situation was a sign of the success of alchemy.

Sure enough, an hour after the pregnancy pill, Lin Feng opened the pill furnace, and saw four milky white pills in it, and some medicinal residues, and saw that he had directly succeeded in refining four pills in one attempt, Lin Feng was already very satisfied, after all, for a completely unfamiliar pill, he could have such a great success rate, which was enough to prove that his basic skills were solid.

Although the Jiyuan Pill has been refined, Lin Feng still does not know the real medicinal effect of the Jiyuan Dan, although he has seen the specific effects of the Jiyuan Dan in the ancient books, but whether he has successfully refined the Jiyuan Dan or not, Lin Feng is not at all sure, so after carefully identifying and recording the smell of the Jiyuan Dan, the shape and the halo on the Jiyuan Dan, he directly sent the Jiyuan Dan into his mouth and swallowed it.

Next, Lin Feng's encounter was exactly the same as Liang Dong's, and a large amount of heaven and earth aura appeared around him to pour into his body, Lin Feng's realm had just entered the middle stage of true immortal, but after the medicinal effect of Jiyuan Dan passed, Lin Feng found that as long as his spirit could be improved, then he could directly break through to the late stage of true immortal, so he originally needed to refine and accumulate for a longer time to be able to make his true yuan full, but now it was completed in just half an hour, if this kind of pill can be popularized, then the cultivation speed of the disciples in his own sect can definitely be slightly improved。

Originally, Lin Feng was not going to say the matter of his successful refining of Jiyuan Dan at this meeting, after all, he had just refined it once, and he didn't have a special understanding of the refining situation of this Jiyuan Dan, only after refining it many times, let himself be more familiar with the refining method of Jiyuan Dan, as well as the approximate success rate of this Jiyuan Dan, it was not too late to bring it up, not to mention that at that time, the Jiyuan Dan in his hands would be able to accumulate some, and then he could directly issue one to the disciples in the sect, which could be regarded as a welfare distribution for the disciples of the Hua Sect！

However, the plan couldn't catch up with the changes, Lin Feng didn't expect that just when he came to the Elders' House, Zhang Yuan sighed at everyone's hard work, and in an instant, all the disciples were actually emotionally reduced, Lin Feng was afraid that Zhang Yuan would directly give up those natural treasures because of his compassion for the disciples, so he took the first step to tell the matter of Jiyuan Dan.

For the story Lin Feng said, maybe others don't understand, but Lin Feng understands that Lin Feng happened to be in the medicine field in the forbidden land at that time, so the sound of the vicissitudes of life should come from Taishang Laojun, otherwise, how could Lin Feng get the refining method and refining materials of Jiyuan Dan for no reason, thinking of this, Lin Feng still felt a little grateful to Taishang Laojun in his heart.

However, for the matter of Taishang Laojun's help, Zhang Yuan temporarily put it down, Zhang Yuan was thinking of another possibility at the moment, not to mention whether this episode of Yuan Dan would really be able to improve a small realm, even if it could not be improved to a small realm, according to what Lin Feng said, it was already very powerful, and Lin Feng felt that this episode of Yuan Dan seemed to be able to be used in battle, but Zhang Yuan also just thought about it, whether it could be successful, Zhang Yuan could not be completely sure, so whether the specific set of Yuan Dan would help in the battle, Zhang Yuan decided to try it himself。

Took the last two Jiyuan Pills from Lin Feng's hands, and then Zhang Yuan asked Lin Feng and Xin Feizi to leave temporarily, because the second rebellion was about to begin, since this moment can refine this kind of pill that can instantly increase everyone's strength, Zhang Yuan of course wants all the disciples to be able to improve some strength, only when the strength is improved, the safety of Huazong's disciples is more guaranteed, so Zhang Yuan asked Lin Feng to refine two Jiyuan Dan for each disciple of Huazong as quickly as possible.

After Lin Feng left, Zhang Yuan led the remaining disciples to the courtyard outside the Elder's Courtyard, and after looking at the mountains in the distance, Zhang Yuan casually slapped a palm, but the surrounding mountains were also made of Taiyi Essence Gold, so Zhang Yuan's casual palm did not have any effect, after seeing the result, Zhang Yuan sent a Jiyuan Pill into his mouth, and the aura of heaven and earth began to quickly gather around Zhang Yuan, and quickly poured into Zhang Yuan's body, and then Zhang Yuan slapped at the mountain range in the distance again, but this time Zhang Yuan used only a trace of the true yuan, and more of them are those heaven and earth auras that are entangled by the true element.

"Boom!", a pit dozens of centimeters deep suddenly appeared in the distance.
