{Something happened, just a change today, sorry.} }

In a quiet room of the Qinglong Tribe, Ling Feng sat cross-legged on the bed, absorbing the aura of heaven and earth to restore his cultivation, adjust his state, and prepare for the refining of the Dan Furnace.

The Dan Furnace required by the Dan Master and the Dan Furnace required by the Alchemist were not only different in appearance, but also different in terms of production methods.

Today's alchemist's Dan furnace is all using the forging technique, but what he wants to use today is the refining method, which is almost two different concepts from the forging technique.

After an unknown period of time, Ling Feng's cultivation had returned to its peak, and his spirit had completely recovered.

"It's time. Ling Feng slowly opened his eyes, and his heart moved, he had already come to the Emperor Pearl.

Refining the Dan Furnace is not an easy task, and it also requires the use of Vajra Flame, which is not something that ordinary brick houses can withstand.

Moreover, his time was limited, and three days was simply not enough, but with Dizhu, he had four times as much time, that is, twelve days.

He had calculated before that it would take about nine days to refine the Dan Furnace, and in order to prevent accidents, he had only extended the time by one day.

After entering the Emperor Pearl, Ling Feng directly carved out a space, and then took out many of the materials he had prepared before.

The Golden Crystal Iron Jade, the Phoenix Blood Stone, the Dragon Pattern Blood Crystal, and a small piece of Ten Thousand Mother Iron Essence that he had obtained from Nalan Yanran, as well as some other materials needed to refine the Dan Furnace, were all placed in front of him.

"Suzaku, come out. Ling Feng let out a low snort, and the Vermilion Bird flew out in response, Ling Feng connected with its divine soul, and then saw it open its mouth and spew out a ball of Vajra flames.

However, he did not rush to put the materials in, but closed his eyes and recalled the whole process of refining.

After half a sound, Ling Feng suddenly opened his eyes, and with a wave of his right hand, a piece of golden crystal iron jade was punched out, and then he used his true qi control to hold it above the Vajra Flame.

As I said before, this Golden Crystal Iron Jade is most afraid of the energy of the fire attribute, and at the beginning, Suzaku was only a second-order, so it could affect the Golden Crystal Iron Jade, and at this moment, it was not much different from roasting it on the Vajra Flame and roasting it on the fire.

Since it was the first time, the grasp was not very good, and as soon as it touched the Vajra Flame, the golden crystal iron jade was dyed into ashes.

"It's harder than you think. After Ling Feng patiently tidied up, he took out a piece of Golden Crystal Iron Jade again and threw it over, this time it was much better, but in the end, he still couldn't escape the fate of being burned to ashes.

Weak Zhao Wuji is here at the moment, and he will definitely scold Ling Feng for being a loser.

You must know that the method of refining is different from forging, forging and striking iron are not much different, and the requirements for flame are not particularly high, so no matter how bad it is, it will only melt the material.

But refining is different, refining requires a flame like the Vajra Flame, and only in this way can the degree of fusion of various materials be close enough.

But for beginners, the first thing to do is to understand the flame, only to understand the characteristics of the flame, can we talk about what to do next, of course, the best way to understand the particularity of the flame is to try refining.

But in general, the material that beginners try is very ordinary, because the process is simply a waste of money.

But Ling Feng actually used the Golden Crystal Iron Jade to practice his hands, not to mention Zhao Wuji, even if any martial artist knew about it, I am afraid that he would not be able to treat it calmly.

After all, this golden crystal iron jade is also a rare material.

Ling Feng didn't care so much, fortunately, Ling Feng had enough gold crystal iron jade on his body, otherwise, before he started practicing, the materials would be wasted by him.

After nearly half a day of exploration, I finally had a certain understanding of the nature of this Vajra Flame, and there was no more situation where the Vajra Flame burned out.

At this time, after the cauterization of the Vajra flames, the golden crystal iron jade had become very soft, and then the appearance of the Dan furnace appeared in Ling Feng's mind, and then he hugged his hands in front of his chest, making a strange handprint.

This was not an ordinary handprint, every time a handprint was made, some of the true qi in Ling Feng's body would be consumed, and these true qi were affected by the handprint, becoming extremely condensed, directly acting on the golden crystal iron jade.

Strange to say, as the handprints continued to be typed, the shape of the golden crystal iron jade began to change, as if there was a pair of invisible hands, fiddling with the golden crystal iron jade.

However, gradually, the consumption of true qi in this process was extremely terrifying, and he could not touch a hundred handprints, and the true qi in his body was consumed.

Without true qi, the handprint could not have an effect, and only heard the sound of "bang", and the golden crystal iron jade that already had the shape of a Dan furnace was instantly dyed into ashes by the Vajra flame.

Although he failed again, Ling Feng did not lose heart, took out a few Gathering Spirit Pills and took them, and soon became true qi.

"Come again. Ling Feng was not someone who would give up casually, after adjusting his condition, he took out a piece of Golden Crystal Iron Jade again and threw it into the Vajra Flame.

With the reason for his previous failure, Ling Feng learned to be obedient this time, and took the Green Dragon, White Tiger, and Xuanwu into his body, allowing them to absorb the aura and transform it into true qi for his own use.

With their help, his pressure was much less, and soon nearly a thousand handprints were completed, and the golden crystal iron jade had been shaped into the shape of an incense burner, with three legs standing under it, and two ears on the top were erected, which was very exquisite.

However, Ling Feng knew that this was only the first step, and the next step was the key.

Then there was a series of handprints, but this time the shape of the Dan furnace did not change much, but there were strange patterns on it, although I don't know what they were, but it looked very mysterious.

The entire refining process is divided into four steps, the first step is forging body plasticity, that is, making it into the appearance of a Dan furnace, which is the step that Ling Feng has completed at the moment.

The second step is to engrave the pattern.

This formation pattern is not something from this era, but something from the previous era, according to Zao Wou-ki's memory, Ling Feng believes that it should be a kind of writing, a kind of writing that only heaven and earth can understand.

These "words" can be combined together like articles, different combinations have different meanings, and when these "words" are activated, they can hook the power of heaven and earth.

It's a pity that the formation pattern has been lost a long time ago, and what Ling Feng knows is only ninety-nine eighty-one, and all of them are used to engrave on the Dan furnace.

Although, he remembered these formations, but he didn't know what they meant exactly, because even Zao Wou-Ki didn't know, he was just copying them.

The third step is smelting and reinforcing.

To put it bluntly, it is to integrate some other things into the furnace embryo that has been plastic, and here it is to fuse the phoenix bloodstone, dragon pattern blood crystal and ten thousand mother iron essence into it, so as to make the Dan furnace stronger, more stable, or add some special properties.

For example, the dragon pattern blood crystal, after being integrated, the dragon pattern is transferred to the Dan furnace to enhance the strength of the Dan furnace, or the phoenix blood stone, which can greatly increase the temperature that the Dan furnace can withstand.

As for the last step, which is actually the most critical step, there is quenching.

Anyone with a little forging knowledge knows that the quality of quenching directly determines the final level of a divine weapon, and it can even be said that no matter how perfect you do in the first three steps, if the last step is not good, it will also directly affect the quality of the divine soldier.

Therefore, some great powers, in order to be able to forge a good divine weapon, even spend years looking for quenching solvents.

And the most difficult thing for Ling Feng was the first three steps, because he had the best quenching solvent above Tianwu, and there was Extreme Yin Water, that is, as long as he completed the first three steps well, then he could refine a good Dan furnace.

But even for a veteran refining expert, the first three steps would be difficult to accomplish in one go, and there would even be several failures, let alone Ling Feng.

In the next five days, Ling Feng finally completed the second step without knowing how many times he had failed, and all the nine nine hundred and eighty-one formation patterns were engraved on the Dan furnace.

"Whew-" When the last formation pattern was successfully engraved, Ling Feng couldn't help but breathe a sigh of relief.

But at this moment, the Vajra Flame slammed away, and the entire Dan Furnace was reduced to ashes again.

"My day. Ling Feng, who was angry in this situation, wanted to scold his mother, struggled for a few days, and finally got better, but it was all in vain because of an oversight.

However, Ling Feng didn't know that even he, if he was another person, it would be impossible for him to complete the second step in such a short period of time, of course, he could do this step, Zao Wou-Ki's experience played a decisive role, but Ling Feng's talent was not covered.

Gritting his teeth, he calmed down again, this time he didn't continue refining, but closed his eyes in order to recover his cultivation, while summarizing and digesting.

In the past five days, he was very tired, especially the mental attrition, and he didn't dare to be sloppy in the refining process at all, because the result of sloppiness was the same as just now, and all his previous efforts were lost.

After resting for a long time, with the help of Qinglong, the loss of his heart and body has almost recovered, and he has also found a benefit, that is, the continuous output of true qi, making his true qi more vigorous, which can be regarded as an unexpected joy.

After adjusting, he refined it again.

This time, the refining process was very smooth, and the first two steps were completed in the blink of an eye, with almost no mistakes in the middle, and then the two were devoted to two purposes, while warming the furnace embryo, while preparing to melt the phoenix bloodstone.

At this moment, he didn't dare to be careless, because the phoenix blood stone and the dragon pattern blood crystal were only one piece, and once they were damaged, there would be no second piece available.

Therefore, Ling Feng's spirit was also highly concentrated at this moment, and only the Vajra Flame and materials were left in his eyes.

As soon as Ling Feng pushed, the phoenix bloodstone was controlled by the true qi and flew above the Vajra flame, and in less than a minute, this phoenix bloodstone was melted into liquid, like blood, extremely scarlet.

Without thinking about it, Ling Feng poured the scarlet liquid into the Dan Furnace, only to see that the Dan Furnace shook, and the color immediately changed, and finally turned into a crimson gold.
