With irrepressible surprise, the black robe took the pill in his hand as if he was admiring a work of art, and admired it for a long time, and then he reluctantly put the pill into his mouth. Pen ~ fun ~ pavilion www.biquge.info

In an instant, a powerful vitality erupted in the belly of the black robe, and the black robe let out an irrepressible moan, and quickly sat down on the spot to refine the pill.

Half an hour later, the black robe's body trembled violently, and the surprise on his face was even worse. This pill actually allowed him to break through to the seventh layer of qi refining.

"Master, this pill is amazing, this pill has saved the old slave at least a month of cultivation time", the black robe finally opened his eyes and said excitedly.

Qiu Fenglin congratulated the black robe, but muttered in his heart: According to Pei Yuan Dan's introduction, the effect of this Pei Yuan Dan should not be so great, right?

Although Pei Yuan Dan was the most commonly used pill for low-level cultivators before the foundation building period, it was the most effective for junior cultivators.

According to the above introduction of the jade slip, even for low-level cultivators, the dosage of Pei Yuan Dan can at least take one a day, or even more.

If calculated in this way, like a black robe, one is like more than a month of cultivation, then wouldn't this pill be against the sky?

"This kind of elixir has such a powerful medicinal effect in your cultivation era?", Qiu Fenglin asked the black robe puzzled.

"This, this, when the old slave cultivated in his last life, his status was low, and he was also very poor, and he really hadn't taken this kind of pill. The exact effect is also not very clear. However, as far as the old slave knew, those monks who were able to take these pills seemed to be really not as effective as the pills that their masters had refined. Because among those powerful forces, there are still many monks who take this elixir, and some even eat them as jelly beans, which is not uncommon. If the medicinal effect of those Pei Yuan Dan was like the effect refined by the master, wouldn't it be as easy for those monks who took this pill to improve their cultivation? Moreover, the old slave was promoted from the sixth layer to the seventh layer this time, that is, the middle stage of Qi cultivation was promoted to the late stage of Qi training, which was also a huge hurdle for low-level monks."

Qiu Fenglin listened to the words of the black robe, and felt even more strange in his heart, could it be that it was his own alchemy method, which was much more sophisticated than the alchemists of the ancient cultivation era?

But Qiu Fenglin knew that this was completely impossible.

Although he has refined a first-level elixir, he can barely be said to have become a first-level alchemist. But his own means know that even if he is a first-level alchemist now, his level is the worst among the first-level alchemists.

So what is the problem with this medicine being so effective?

Qiu Fenglin thought about it, and suddenly found a possibility, so he asked the black robe: "At that time, when you were refining Peiyuan Dan, how old were you usually using medicinal materials?"

When the black robe heard this, he suddenly realized, and suddenly said: "The master is very smart, and the problem should appear here." In our time, there were monks everywhere, how could the elixir grow so easily and quickly, but some elixirs with a year had already been exhausted. Generally, these medicinal materials for refining Pei Yuan Dan are three or five years old, and at most they will not exceed ten years. Being able to collect an elixir that is decades or hundreds of years old is already a stroke of luck against the sky. Although the old slave had never taken the pill, he still often collected medicinal herbs. If you collect the elixir, you can also exchange it for some other cultivation resources."

Qiu Fenglin finally understood, this is all the elixir at work.

Although Pei Yuan Dan was only a first-class elixir, in the era of cultivation, the elixir used was no more than ten years at most.

But what is the concept of the elixir that I am using now?

The formation arranged by the old evil of Bijie has not been brought in for at least seven or eight thousand years. Even if there is a vein of vitality here, most of the vitality supports the operation of the formation, and the remaining vitality cannot be sufficient to supply the elixir for growth, and it is normal for those higher-grade elixirs to not grow.

But this part of the remaining vitality is just enough to meet the growth of these low-level elixirs like the third-level elixir.

Although there are also life and death changes in these elixirs below the third level, many of them have grown to the limit of their lives and died. But the elixir that grows in the mountains now is generally able to grow to the extreme age. The medicine is long, one or two thousand years, and there are still some of them. Those who are hundreds of years old are even more numerous.

When people refine Pei Yuan Dan, they use elixirs within ten years, but they use them for at least hundreds of years, so it is impossible for these pills to have a bad effect.

Qiu Fenglin thought about it like this, and suddenly came to his senses.

The treasures left to him by the old evil of Bijie are not those things that have been obtained or not obtained in the cave. It's such a huge treasure trove of medicinal herbs within a radius of hundreds of miles.

According to the elixir map left by the old evil of Bijie, Qiu Fenglin has also compared it, and these elixirs in the mountain range, the highest grade, are only level three.

But just these elixirs below the third level are already very remarkable.

The first-level elixir is suitable for monks below the foundation building period to refine the elixir. The second-level elixir, that is used by the monks of the foundation building period. And the elixir refined by the third-level elixir is the elixir used by the Jindan stage cultivators.

To what extent the strength of the Jindan period cultivator, Qiu Fenglin didn't even dare to imagine it now. And these elixirs are enough to allow him to cultivate without worry before the Yuan Infant Stage, such favorable conditions, I am afraid that even those low-level cultivators in the Heavenly Realm dare not imagine it.

Thinking of this, Qiu Fenglin suddenly had the urge to slap himself a few times.

He studied alchemy by himself, and to this day he has refined the first furnace of Peiyuan Dan, and at least hundreds or thousands of furnaces of medicinal materials have been refined.

With so many medicinal materials, if all of them were refined into pills, what a huge amount would that be? Bringing these pills to the Heavenly Realm would probably be a lot of wealth, right?

However, this regret is also slightly redundant.

This alchemy was originally piled up with elixir, and if he didn't consume so many elixirs, how could he refine Pei Yuan Dan today?

Qiu Fenglin could only secretly make up his mind that in the process of studying alchemy in the future, he must be cautious and suppress the medicinal materials consumed by his study of alchemy to the lowest amount.

Today's discovery also made Qiu Fenglin have another plan.

His own Pei Yuan Dan has such an effect against the sky, and it is impossible to see it in the heavenly realm. Then before entering the Heavenly Realm, he should have prepared more of this elixir. Especially the pills of the foundation building period, or even the pills of the Jindan period, you must learn to refine them as soon as possible. When the time comes, bring enough of these pills, and only by cultivating can you have no worries.

With the success of the first furnace, the subsequent learning will be much smoother.

Two months later, Qiu Fenglin had mastered all the refining of Pei Yuan Dan and Buzhen Pill, and the Cheng Dan rate had reached seventy percent.

However, when he was learning to refine the True Yuan Pill, Qiu Fenglin ran into trouble again.

Zhenyuan Dan is an elixir that is refined using a combination of first-class medicinal materials and second-level medicinal materials, and its grade is also between a first-level pill and a second-level pill, which can barely be regarded as a second-level pill.

Alchemy is a process in which the body and consciousness work together. But now Qiu Fenglin's cultivation has not yet reached the stage of Dacheng. At this time, Qiu Fenglin realized that his divine sense could not support the refining of second-level pills.

After practicing a few furnaces of elixir, Qiu Fenglin couldn't see any hope of success, and Qiu Fenglin was a little desperate. While feeling distressed about the elixir, Qiu Fenglin became worried again, when will this bottleneck of cultivation be broken, and this bottleneck will not be stuck in his life for a lifetime, right?

If you can't cultivate and don't succeed in alchemy, what should you do?

Qiu Fenglin was helpless, and was ready to improve his formation means again.

But now that his cultivation can't be improved, how can Qiu Fenglin calm down and cultivate, under the irritability in his heart, after a few days of hard work, not only can the formation level not be improved, but he even feels that there is a kind of anger in his heart, and he actually has an urge to kill from time to time.

"Master, it can't go on like this. With such a mentality, it's easy to go crazy", the black robe finally found out that Qiu Fenglin was wrong, and hurriedly reminded.

"Then what should I do? Is it just like that, staying here for the rest of my life?", Qiu Fenglin forced himself to resist the urge to scold and asked.

"The master hasn't been out for a long time, or go out for a walk, so that the master's mood can be calmer," the black robe suggested.

Qiu Fenglin thought about it, it was indeed true, if he continued to cultivate or study like this, he would go crazy.
