The difference between a Dan Furnace and its own level is not only based on its own level, but also on the medicinal power contained in it, in other words, the number of times the Pill is refined.

In contrast, the latter is more important.

It can be said that the more medicinal power a Dan furnace of the same level contains, the better the Dan furnace will be.

Because every time you refine a pill, a part of the medicinal power is absorbed by the Dan furnace, and the next time you refine the pill, these medicinal powers will be absorbed by the pill, which will not only not affect the medicinal properties of the refining pill, but also improve its medicinal effect.

This is like a wine vat for winemaking, after a long time, it will have a wine aroma on it, and the wine made from it will taste better than other wine vats.

Ling Feng's dragon pattern dark gold furnace is made of the best materials such as gold essence iron jade, dragon pattern blood crystal and ten thousand mother iron essence, the flame is the vajra flame that is tied for the first place in the three lists of strange fire, and the king of the fire and the danhuo double list, and the quenching is even more of the best quenching thing, extreme yin water, and the refining method is the method of ancient refining.

It can be said that every process of it is perfect, although the level is not as good as a true artifact, but even if it is a real artifact, it cannot be compared.

Moreover, the refining of the Dan Furnace is different from ordinary weapons, and there are very few Dan Furnaces that can reach this level, I am afraid that even the sixth-grade alchemist only uses a mid-to-low-grade spiritual weapon, which cannot be compared to his Dragon Pattern Dark Gold Furnace at all.

As for the medicinal power, although the Dragon Pattern Dark Gold Furnace had only refined more than a hundred pills since it was cultivated, the number of pills refined each time had reached as many as a thousand.

Counting up, this dragon pattern dark gold furnace has already refined more than 100,000 pills, and all of them are fourth-grade pills, which is more than the number that ordinary fifth-grade alchemists have refined for decades.

Because if there is no special need, the number of pills they refine each time will be controlled within one to three, because the smaller the number of pills, the lower the consumption of the mind.

Therefore, the level and medicinal power in this dragon pattern dark gold furnace are not comparable to ordinary alchemists.

If Ling Feng wanted to sell the Dragon Pattern Dark Gold Furnace, it would definitely cause a sensation, and even the Dan Dao Sect Master would be alarmed and fight for it.

Because for an alchemist, a good Dan furnace is no less attractive to them than fire.

However, what Ling Feng was most satisfied with was not the level of the Dragon Pattern Dark Gold Furnace and its rich medicinal properties, but his own understanding of it, because this Dan Furnace was refined by his own hands, and Ling Feng knew every detail of it.

It's like an extension of a part of his body, and it's more handy to use.

After a slight adjustment, Ling Feng summoned the Vermilion Bird out and prepared for alchemy.

At this time, Suzaku had already refined Li Mufeng's fire, and he had also learned about it in the past few days, Li Mufeng's fire was called Wuxiang Hellfire, which was not the fire on the two lists of Danhuo and Instrument Fire, but the eleventh fire on the martial fire list.

Tianwu, fire is divided into three types according to their specific use, Danhuo, instrument fire and Wuhuo.

As the name suggests, Danhuo and Vessel Fire are the fires that can be used for alchemy or refining, the common feature of these two flames is high temperature, and the use of this flame for alchemy or refining can increase the success rate of the pill and increase the efficacy of the pill.

But apart from alchemy and refining, the use of these two flames is very limited, although few people can withstand the high temperature of the Dan fire or the fire.

However, if you want to kill the enemy with Dan Fire or Weapon Fire, you must burn them until they can, and if you can't burn them, no matter how powerful you are, it will be useless.

And martial fire, compared to Danhuo and instrument fire, their temperature is not very high, and some are even extremely cold, and their abilities are strange.

For example, this phaseless fire has no fixed form, just like a liquid, it can be composed of any shape at will, including all kinds of creatures.

After the Vermilion Bird Devourer's Phaseless Flame was obtained, it obtained its ability, and the flames released could be controlled at will, changing into the form of a human being.

And the flames in Suzaku's body also changed again, turning gray-gold, but the power was even more powerful than before.

Suzaku jumped onto his shoulder as before, opened his mouth, and suddenly a gray-golden flame shot into the dragon pattern dark gold furnace, only to hear the sound of "crackling" coming from the Dan furnace, Ling Feng found that this dragon pattern dark gold furnace was a little unable to withstand the scorching of this flame.

In this situation, he challenged, to know that his Dan furnace had cost him a lot of effort, how could he let him be burned like this, and hurriedly activated the eighty-one formations on the road, and a faint fluctuation came from the road, and the next moment, the Dan furnace calmed down, and there was no sign that he couldn't bear it.

"These formations are amazing, they have to be figured out. Ling Feng reminded himself again, then took out the ordinary medicinal herbs and began to test the properties and temperature of this flame.

Soon he found that the fire after fusing the Phaseless Flame was not much different from before, except for gaining the ability to change form and changing the color.

After determining this, Ling Feng grasped it again in his heart, took out the medicinal materials needed to refine the True Martial Pill, placed them in front of him one by one, and began to sort out the refining process of the True Martial Pill.

When it was all digested, he threw the herbs into it one by one.

Under the high temperature of the flame, the main medicinal ingredients in these medicinal materials were extracted, and some impurities were also refined into fly ash at this time.

Ling Feng's divine thoughts were released, forming two invisible big hands, gathering the essence of these medicinal materials together to form a pill shape, and then with the help of Vermilion Bird, Ling Feng easily pulled out a ball of flames, and instantly wrapped this pill.

This is not a process unique to the True Martial Pill, but this method is only used when refining pills above the sixth grade, and it has a fixed name, Yun Dan.

The so-called Yun Dan is to use flames to wrap it to form a relatively closed environment, without harming the drug itself, at a relatively high temperature, to promote the reaction between these drugs to form a high degree of fusion.

The reason why the True Martial Pill can be used in this way is that it is not an ordinary four-grade pill, but an elixir that helps people break through the realm, and it is not an exaggeration to say that it has a rebellious nature.

Moreover, this process is not achieved overnight, and it takes a long time, generally speaking, it takes three to five days for the short ones, and ninety-nine eighty-one days for the most ones.

However, after all, the True Martial Pill is a four-grade pill, and the time required is short, according to Zhao Wuji's calculations, it should take six days.

Ling Feng was afraid that he would not be able to complete the refining of the True Martial Pill at one time, so he took two more medicinal materials and finished refining them as before.

Without Suzaku's help, Ling Feng would definitely not have been able to do this.

Because Yun Dan is a very delicate job, it has extremely high requirements for the alchemist's ability to control goods, and he must always keep his heart and soul into it, and if he is not careful, his efforts will be wasted.

Even if it is a seventh-grade alchemist, he can only cultivate two pills at the same time at most, and three pills are simply impossible.

And with Suzaku's help, Ling Feng didn't have to worry about Yundan's process at all, and for Suzaku, controlling fire was a simple thing that couldn't be simpler.

There is no way, people are the kings of fire, and controlling goods is a natural instinct for them like a blink of an eye, and they don't need to spend anything to have a natural advantage.

So, in the past few days of Yun Dan, Ling Feng was the same as usual, between the classroom and the practice room, the days passed and the anger and love, and in a blink of an eye, six days had passed.

In the practice room at this time, Ling Feng sat in front of the dragon pattern dark gold furnace, and with the help of Vermilion Bird, he easily removed the flame wrapped in a pill.

Don't look at this step, it was very simple for Ling Feng, but for many alchemists, it was a chasm that was difficult to cross.

In the past few days, the medicinal herbs have been perfectly fused together under the impetus of the relative high temperature, and at this time, the sudden withdrawal of the flame is like throwing a hot porcelain into cold water, and the result can be imagined.

Therefore, this process needs to control a constant temperature, even if it is an experienced Dan Master, he has to take it slowly, how can he withdraw directly like Ling Feng.

After this pill embryo gradually "cooled", Ling Feng began to make one handprint after another, and with each handprint, the volume of the pill would shrink by one point.

The original fist-sized pill, after hundreds of cashiers, was only the size of Longyan.

Ling Feng knew that the most critical step had arrived.

"Knots. Ling Feng let out a low shout, and the handprint of the Jie Dan was instantly punched, and then immediately glanced at Suzaku, who seemed to understand what Ling Feng meant, and the flames slammed away, wrapping it again.

I only heard the sound of "bang", like the muffled sound of a bean bursting, and the next moment, a wisp of black smoke came out of the flame and was absorbed by the Dan furnace.

"Failed. Ling Feng exhaled, this result was also expected by him, after all, it was the first time to refine the True Martial Pill, how could it be so easy to practice.

So he quickly adjusted his mentality, sorted out the mistakes he might have made before, and began to refine the second one.

Unfortunately, the second one also failed.

This time, he didn't rush to refine, but combined with Zao Wouji's memory, he summarized it well, and then started refining.

And when his last handprint was typed out and the word "knot" was shouted, suddenly a thick dark cloud appeared in the sky above the Shining World Secret Realm, and a terrifying coercion penetrated the protection of the secret realm and descended on Ling Feng's body.

"This is ......" This situation attracted the attention of many people, and everyone raised their heads one after another, with a slight weirdness between their eyebrows.

"Tribulation, it's calamity, which elder refined the best elixir or artifact!" Someone recognized the origin of this dark cloud and immediately exclaimed.

It's no wonder that this person guessed so much, it is not particularly difficult to get started with refining medicine and refining weapons, but it is easy to learn and difficult to refine, and it is not difficult to refine ordinary pills and artifacts.

But if you want to practice the best elixir or artifact, you not only need to have a deep understanding of the Dan Dao or Instrument Dao, but also need a strong cultivation to do it.

In the entire Yaoshi Secret Realm, only a few elders could cultivate such a treasure.
