On the back mountain, Xiao Yi comprehended the five elements of Ning Dan.

Today, Yi Lao's teaching has benefited him a lot.

At least it won't be like last night, like reading a book from heaven.

I have to say that Yi Lao's teaching skills are really powerful.

Those obscure knowledge of alchemy, complex and mysterious combinations of medicinal materials, when he said it, it easily became concise and clear knowledge.

The method of refining the elixir and removing impurities.

It is in the process of alchemy, when the pill is about to condense the pill, add the demon beast inner pill.

In the process of refining the elixir, the heavenly and earthly treasures added will more or less carry various attributes.

Such as 100-year-old Xuanshen, earth attribute, demon blood flame heart fruit, fire attribute, Peiyuan Zhuguo, wood attribute, hemlock branch, metallic....

For example, most of the materials used to refine the Snow Pill are ice attribute materials.

Therefore, the refined elixir, in fact, more or less, will have a little attribute.

The Five Elements of Ning Dan Record relies on these attributes to remove the impurities of the pill through the demon beast inner pill.

Of course, the pill has impurities, and the demon beast inner pill also has impurities and a brutal aura.

However, the five elements are mutually reinforcing and mutually restrictive.

For example, an elixir with ice attributes.

In the process of condensing the pill, adding the ice attribute demon beast inner pill can greatly increase its own ice attribute.

Before it is completely formed, the impurities are 'squeezed out'.

This is called symbiosis.

As for the impurities and brutal aura on the Ice Attribute Demon Beast Inner Dan, you only need to add the Fire Attribute Demon Beast Inner Dan to fight against ice and fire to eliminate the impurities and brutal breath.

This is called mutual restraint.

As a result, the impurities on the pill and the impurities on the demon beast's inner pill can be completely eliminated.

To sum it up, it's one sentence.

Mutual growth, in addition to the impurities of the pill, and in the restraint of the demon beast, in addition to the impurities in the demon beast.

This is the principle of the Five Elements of Ning Dan, and it is also what Yi Lao teaches today.

"It's no wonder that in the batch of commercial goods that were looted before, in addition to daggers, poisons, and finished pills, there are also so many demon beast essence blood and demon beast inner pills. Xiao Yi muttered to himself.

"The Shadow Building, there are many killers. The blood of the demon beast spirit is used for the killers to take a medicinal bath, improve their cultivation, or have other uses. ”

"The Demon Beast Inner Pill is used by the alchemists in the Shadow Building to refine the pill without impurities. ”

The Five Elements of Ning Dan is not unique to the Heaven Splitting Sword Sect.

According to Yi Lao, this is a method that some advanced alchemists must learn.

However, in the entire Beishan County, there are only three people who can have this ability, not counting the Sky Splitting Sword Sect.

These three are all alchemists of major forces, one is in the Demon Hunting Palace, one is in the Shadow Building, and the other is under the command of the King of Beishan County.

And these three people, although they are all fifth-grade alchemists, are far inferior to the elders of the Medicine Hall of the Heaven Splitting Sword Sect.

Therefore, even if these three people have this ability, they are very slow to refine the pill without impurities, even pitifully slow.

Straight to the point.

Principle is principle.

The principle, Yi Lao taught it in one day, it is not difficult, and it is easy to understand.

But it is very difficult to actually implement it.

If a pill has one attribute, it is necessary to add two demon beast inner pills with the same attribute of restraint.

But in fact, the elixir is made by the fusion of many kinds of heavenly and earthly treasures.

Therefore, there is more than one attribute.

This requires the addition of more demon beasts in the Inner Dan.

The greater the number of demon beasts, the more attributes have also become.

As a result, the combination of different attributes becomes quite complicated.

In the alchemy furnace, the heavenly and earthly treasures are burned by high-temperature flames, in fact, most of the attributes have been burned, and there will only be a little left.

And this little bit is the residual attribute of all kinds of heavenly and earthly treasures.

Which of these attributes is stronger or weaker? Is the fire attribute more vigorous, or the wood attribute more prosperous?

At this time, it is necessary to add the demon beast Neidan with different energy strengths accordingly.

In short, these combinations are ever-changing, and it is impossible to say enough.

It is the most important test of the alchemist's ability.

Refining medicine is a very complicated matter in itself, and although the Five Elements of Ning Dan can remove impurities, it has increased the difficulty by ten times or more than a hundred times.

It is precisely because these combinations are too difficult that the alchemist needs to have an incomparably rich knowledge of alchemy.

This has stumped countless alchemists, not to mention Ye Ming, even if he is waiting for a five-grade alchemist, he is also helpless.

Even those five-grade alchemists who have been famous for a long time and understand the Five Elements of Ning Dan often have to spend a lot of effort and time on a pill to think about how to join the Demon Beast Inner Dan, so it is very slow.

This has very high requirements for an alchemist's comprehension.

And Xiao Yat's comprehension is frighteningly high.

Under Yi Lao's guidance, he was able to roughly master these combinations within a few months and really start refining medicines.

Yi Lao spent one day teaching the principles, and the rest of the time was spent teaching these combinations and alchemy.

"Months, too long. Xiao Yi shook his head, "And that's only a rough grasp, and the refining speed will be very slow." ”

"If you want to quickly refine an impurity-free elixir, you can only reach the point of integration. However, I don't know how many years from now. ”

"The Eye of the Sun, this time it's up to you again. Xiao Yat muttered to himself.

In the next second, his eyes changed. The left eye is as dark as a black hole, and the right eye is as hot as the sun.

Then, look inside the Bingluan Sword Martial Soul in the body.

He didn't know if it would work, after all, the Five Elements of Ning Dan was not a pill formula, but the knowledge of refining medicine.

But he wanted to give it a try.

Last night, he read the five elements of Ning Dan for the second time, just to write down all the content on it.

After a few seconds, when his eyes returned to normal, his face was visibly happy.

Because, all the knowledge on the Five Elements of Ning Dan was reduced to the simplest content in his mind.

Those so-called complex combinations, the five elements are mutually reinforcing, and at this moment, it is easy for him.

He was even sure that he was now perfect enough to easily refine the impurity-free elixir.

"It really can. Xiao Yat was secretly shocked in his heart, and he was extremely happy.

.....

Early the next morning, Xiao Yat went to the outer gate treasure house again.

Of course, he didn't tell Yi Lao that he had completely comprehended the Five Elements of Ning Dan.

In just two or three days, he completely realized that this is no longer a genius, it is simply a monster.

Yi Lao guided as always.

However, Xiao Yat deliberately accelerated his learning speed.

Half a month later, he told Yi Lao that he had fully understood.

Inside the treasure house of the outer gate, Yi Lao looked at Xiao Yi with a smack.

"Boy, are you a monster? According to my guess, I thought it would take you months to start understanding, but it's only been half a month, and you've fully understood. ”

In the past half a month, Yi Lao has spent all kinds of surprised expressions.

When teaching Xiao Yat every day, the difficulties in the record of the five elements of Ning Dan, whenever he just finished explaining, Xiao Yat had already drawn inferences and skipped directly.

In some places, there are even more unique insights that can be given, no, they are simply perfect insights.

Sometimes, he felt that Xiao Yat was more like his instructor, and he knew more than he did.

Xiao Yi smiled bitterly, he had long expected that Yi Lao would have this expression.

Fortunately, it was delayed for half a month before he said it, otherwise, Yi Lao would definitely treat himself as a monster directly.

As for those inferences, there are also perfect insights, he has perfectly understood the content of the Five Elements of Ning Dan, and he can naturally do it easily.

"Boy, you...."Yi Lao wanted to say something, but in the end he didn't know what to say.

The surprise that Xiao Yat has given him in the past half a month is completely due to Xiao Yat's terrifying comprehension.

He just thought, perhaps, his previous estimation of Xiao Yi's comprehension was far from enough.

Of course, he looked at the extremely talented 'disciple' in front of him, and his heart was also satisfied.

As a 'teacher' and 'disciple' are excellent, I am naturally very happy.

"Yi Lao, what are you doing?" Xiao Yi quipped, "Do you want to praise me for being good?"

"Hmph. Yi Lao snorted coldly, he really wanted to praise Xiao Yi, but now he said, "Have you forgotten what I told you before? ”

"Now that you've understood it, let's really start alchemy. Yi Lao pouted and said directly, and directly opened the topic.

"Hmm. Xiao Yi nodded, he also wanted to really practice.

The four-grade alchemy furnace was taken out from the fire gold furnace.

At this time, Yi Lao suddenly threw a Qiankun bag.

Xiao Yi was stunned for a moment, and said suspiciously, "Yi Lao, what is this?"

Yi Lao said lightly, "I knew that you could complete those tasks and save enough five thousand sword points to exchange for the Five Elements of Ning Dan." ”

"I also knew that with your comprehension, you would be able to comprehend the Five Elements of the Condensing Pill, so naturally I would have prepared alchemy materials for you in advance. ”

Xiao Yi opened the Qiankun bag and looked at it, and was shocked.

This is a high-end Qiankun bag with a lot of space.

There are countless treasures of heaven and earth, and the lowest ones are third-grade medicinal materials.

There are thousands of demon beasts, and the worst ones are all level three.

"This...."Xiao Yi was shocked, the contents of this Qiankun bag were of astonishing value, even more than several times higher than the batch of goods that robbed Saxo Firm last time.

Xiao Yi knew very well that Yi Lao was a strange and conformist person, although he guarded the treasure house of the outer gate, he would never use half a pen.

proves that these things were all found by Yi Lao himself.

Moreover, it is impossible for Yi Lao to know that he can fully understand it in just half a month, so he may have been prepared a long time in advance.

Just a month ago, when he just came back, Yi Lao was not in the outer treasure house for the first time....

Xiao Yi could already guess that it must have been when he went out to practice before, and as soon as the front foot left, Yi Lao went to prepare these materials for himself.

With such a huge number of Heavenly Treasures and Demon Beast Inner Pills, Yi Lao must have taken a lot of pains.

"Yi Lao...."At this moment, Xiao Yi slowly lay down with a warm current in his heart.

After coming to this world, except for Yiyi and Xiao's parents, only the old man in front of him was so good to him.

"No need to talk nonsense. Boss Yi raised his face and said, "Start alchemy, let me see your level." ”

"Yes. Xiao Yi replied earnestly and began to refine the medicine.

He was going to refine the Dong Xuan Dan, the Dan prescription of the Dong Xuan Dan, long before the previous alchemy guidance, Yi Lao gave it to him, and he would also refine it.

Each piece of material is put into the furnace.

When the Dong Xuandan was about to condense the pill, Xiao Yi quickly put in several demon beast inner pills.

Yi Lao on the side nodded with satisfaction, "Well, the timing is very accurate." ”

In the middle of the night, when a perfect, impurity-free Dong Xuan Pill was refined. Xiao Yi also felt a burst of joy in his heart.

He had already determined that he could quickly refine these impurity-free pills.

Yi Lao took the pill, looked at it for a few seconds, and said, "Yes, it is still a perfect-level pill." ”

"In terms of refining medicine, you should not lose to Ziyan, I heard that he has refined a large number of perfect pills. ”

Yi Lao said in a deep voice, "Zi Yan, this son, is a fire path, and he can control that terrifying Zi Yan, presumably his martial soul is extremely powerful." ”

"Now, you can comprehend the Five Elements of Ning Dan so quickly. Prove that your comprehension is not inferior to his, and may even be stronger. ”

"The level of alchemy should be similar to him. ”

"The only thing that lost to him was the martial soul. ”

Xiao Yi rolled his eyes and said, "Yi Lao, don't you think that others are always in front of me, how powerful they are, and it hits me very much?"

"Blow?" Yi Lao sneered, "In the past half a month, you have hit me very hard. ”

"Besides, if I don't beat you well, you won't be proud to go to the sky?"

"Within the Sword Sect, whether it was Ye Ming, Gu Changkong, or the chiefs of the other halls, they had all been proud and proud when they were the chiefs, which led to the stagnation of their cultivation. ”

"Since I have instructed you in your cultivation, I naturally will not let you take these detours. ”

"Hmph. Yi Lao said coldly, "Those chief disciples of the inner hall, the elders are protecting them like treasures. If you take a detour, you will also be able to solve it. ”

"But I'm not going to be in such trouble. Yi Lao said in a deep voice, "If you are proud and complacent, I will directly throw you into those dangerous demon beast forests in the Eighteen Cities of the Eastern Wilderness, and live alone for ten days and a half months." ”

"Let you see what it means to have a sky outside the sky, and also let you see the power of the peak demon beasts of the Cave Xuan Realm. ”

"I—" Xiao Yi was speechless.
