() Time passes bit by bit.

After nearly half an hour of careful study, Duan Chen took a deep breath, and with a move of his palm, he took out the Purple Immortal Pill that he had just purchased from Baicaotang.

I saw that the whole body of this purple fairy pill is dark purple, the surface is glowing with a faint aura, at the bottom of the pill, there are six fire vents, connected to the inside of the pill, each flame port is also engraved with a formation prohibition, can be opened and closed at will, in order to adjust the flame temperature in the tripod.

In the center of the Danding's body, there is a palm-sized chip, through which the alchemist can easily see the refining of the pill in the Danding.

In addition, there are also some finger-thick silver holes distributed on the tripod cover, which seem to be specially chiseled for heat dissipation, but the holes are distributed on the tripod cover, but it is like a simple star map, which seems to hide a mystery.

In addition, the surface of Danding is also engraved with a series of quaint patterns, which looks natural and majestic.

Looking at this Dan Ding with a simple appearance, Duan Chen nodded with satisfaction, then touched the storage ring on his finger, and with a movement of his mind, he took out the medicinal materials needed to refine the Essence Qi Pill from it.

"Lingyan grass, Biyun fruit, green wood vine...... Before refining the Essence Qi Pill, the essence of these medicinal materials must first be refined. ”

After quickly recalling the steps of refining the Essence Qi Pill in his mind, Duan Chen first opened his mouth and spit out a wisp of magic pill fire, submerged under the Dan Ding, and with a movement of his heart, he threw a Lingyan Grass into the Medicine Ding.

However, the next moment, before he could begin to manipulate the fire of the magic pill to refine the herbal essence in the spirit flame grass, the terrifying fire of the magic pill directly burned the spirit flame grass into ashes.

"No, the fire of the magic pill is too violent, it is not suitable for a novice like you who is learning alchemy at all, I think you should use the fire of the golden pill. The voice of the Seven Demon Lords sounded in Duan Chen's mind.

"Yes. After being reminded by the Seven Demon Lords, Duan Chen also reacted at this time, and immediately withdrew the Demon Pill Fire under the Ding, and then used the Golden Pill Fire in his body to try to refine the herbal essence of the Spirit Flame Grass again.

However, a moment later, the second Lingyan Grass that was thrown into the Danding was still burned to ashes because the flame temperature of the Jindan Fire was too high.

"When controlling the fire, you need to use the power of the divine sense to control it, so that the temperature of the flame can be controlled to the most appropriate degree, and a superficial flame control method like yours will not succeed no matter how many times you try. The Seven Demon Lord reminded again.

Duan Chen nodded silently, and then made a third attempt.

Time passed quickly, and after more than a dozen failures in a row, Duan Chen finally succeeded in refining the Lingyan Grass into a small handful of dark red medicine powder under the guidance of the Seven Demon Lords, and when he smelled it carefully, there seemed to be a faint fragrance faintly exuding from this dark red medicine powder.

"It seems that this refining of herbal essence is not very difficult. Looking at the dark red medicine residue left in the Danding, Duan Chen said with a relaxed expression.

However, just as he was rejoicing about it, the Seven Demon Lords poured a basin of cold water on him:

"No, this quality of medicine is still too complicated, if it is used to refine the essence qi pill, the probability of failure is very large, and even if it is really successfully refined for you in the end, the quality of the essence qi pill that comes out is also the worst one, and it may not be accepted if you give it to others for nothing. ”

"It's not that unbearable. Duan Chen muttered

said a word, but he still honestly put away the dark red medicine powder and continued to refine the herbal essence of Lingyan Grass.

In this way, after Duan Chen's unremitting refining dozens of times, he finally extracted a handful of bright red medicinal powder from the Spirit Flame Grass.

"The finished Lingyan herb powder, the surface is bright red, if you use the power of divine sense to probe and look closely, each pill is faintly crystalline, the herbal essence contained in such a medicine powder is the purest, if it is used to refine the pill, the pill rate will be greatly improved. ”

The Seven Demon Monarch said lightly: "Okay, the medicinal powder of the Lingyan Grass has been refined to this extent, and then it is time to refine the herbal essence in the Biyun Fruit." ”

After a slight pause, he continued: "Biyun Fruit is cold in medicinal properties, and it is not as heat-resistant as Lingyan Grass, so it has higher requirements for the control of Danhuo, so you should pay more attention when refining." ”

"Yes. Duan Chen nodded, and then sent the Biyun Fruit placed aside into the Danding.

This time, perhaps because of his experience in refining Lingyan Grass, Duan Chen only failed seven or eight times before he completely refined the herbal essence contained in Biyun Fruit.

However, in order to reach the standard of being able to refine the Essence Qi Pill, it needs to be refined a few more times.

In this way, under the guidance of the Seven Demon Lords, Duan Chen continued to use the Dan Fire in his body to refine various herbs.

Once the mana and Dan fire in the body are exhausted, they will stop to meditate and breathe, and after the mana and Dan fire in the body are exhausted, they will continue to refine the herbs.

In this way, it took Duan Chen three days to refine more than a dozen medicinal powders and medicinal liquids for refining the Essence Qi Pill.

Looking at the dozen or so medicinal powders extracted from various medicinal materials placed in front of him, Duan Chen let out a long breath, and he couldn't help but feel a sense of satisfaction in his heart.

"Okay, first of all, congratulations on completing the preparations for refining the Essence Qi Pill, and then you can start trying to refine the Essence Qi Pill, I hope that among these dozen or so materials, you can successfully refine a furnace of Essence Qi Pill." "The Seven Demon Monarchs said.

"Absolutely. ”

Duan Chen took a deep breath, and then carefully sent several medicinal powders and medicinal liquids for refining the Essence Qi Pill into the Danding in turn and slowly refined them with the Dan Fire.

However, after only a moment's effort, only a bang was heard, and as the top lid of the Danding was knocked away by the impact of a burst from the furnace, a rich smell of burnt paste permeated the entire quiet room.

Then, without waiting for Duan Chen to react, the voice of the Seven Demon Lords sounded in his mind: "Hurry up and clean up the waste residue and continue the second refining." ”

"Yes. ”

Duan Chen nodded, not caring about being frustrated by the failure of refining the Essence Qi Pill for the first time, so he threw himself physically and mentally into the process of refining the Essence Qi Pill for the second time.

A few days later, after more than ten refining failures, Duan Chen finally succeeded in refining five Essence Qi Pills with slightly uneven surfaces.

"This ......" Looking at the five Essence Qi Pills in his hand that were obviously different in size and slightly black and yellow on the surface, the corners of Duan Chen's mouth couldn't help twitching slightly, and then he couldn't help but sigh heavily.

"Normally, one material can refine at least seven or eight Essence Qi Pills, and the size, color, and shape of each Essence Qi Pill must be the same and round and full, but after all, you are refining the Pill for the first time, so it is not bad to be able to refine it like this. The Seven Demon Lords were relieved.

When Duan Chen heard this, he licked his slightly dry lips, and then fell silent

Silently, he continued to refine the Essence Qi Pill.

Time flew by, and in the blink of an eye, another few days passed.

In the past few days, Duan Chen has been guarding the Danding almost with his eyelids, constantly refining the Essence Qi Pill, and learning from the experience of every failure.

Although this kind of day was boring, when he successfully refined a furnace of Essence Qi Pill that met the standards, the joy still made him feel quite satisfied and gratified.

In the following half a month, Duan Chen successively refined dozens of furnaces of Essence Qi Pills, and only then did he begin to refine the higher-grade Spirit Yuan Pill under the guidance of the Seven Demon Lords.

It is worth mentioning that during this period of continuous alchemy, the mana in Duan Chen's body has unconsciously become more powerful and pure than before, and at this speed, I am afraid that he will soon be able to break through to the peak of Jindan.

Thinking of this, Duan Chen worked even harder to learn alchemy with the Seven Dead Demon Lords.

Whenever the mana in his body was exhausted, he would take the little Lingyuan Pill left in his body to cultivate and replenish it, and before he knew it, time passed quickly.

And when Duan Chen was in retreat to learn alchemy, in the Phantom Moon Demon City, Mu Ye was also constantly helping him inquire about the whereabouts of the Black Silkworm Demon Gu, and finally found out in an auction house that there was a Jindan monk from the Demon God Society who planned to sell a batch of Black Silkworm Demon Gu eggs.

What's even more commendable is that the other party actually has a female worm of the Black Silkworm Demon Gu in his hand.

So on the same day, Mu Ye rushed to the Fox Immortal Residence non-stop and saw the ghost who was in charge of disguising himself as Duan Chen during Duan Chen's retreat.

It's just because the ghost has the mask of the Demon God Society on his face, coupled with the blood refining clone he has taken, it was originally refined according to Duan Chen's appearance.

So when Mu Ye first saw him, he just felt that the aura on the senior in front of him seemed to be slightly different from when they met a few days ago, but he didn't have much suspicion.

"Senior, that's the thing, the eggs of that batch of Black Silkworm Demon Gu and the female worm will be sent to an auction hosted by the Phantom Moon Alliance tonight, if the senior really plans to buy it, you must act immediately. ”

Mu Ye stood in the hall of the cave and looked at the ghost sitting on the main seat in the center of the hall and said.

"Very good, you did a good job, I can't imagine that someone would be willing to take out the female worm of the Black Silkworm Demon Gu and sell it, you can take me to the Phantom Moon Alliance now." Hearing this, the ghost's figure immediately stood up in a flash of gaze.

"Yes, the small one will lead the way for the seniors. Mu Ye bowed and said, and then left the Fox Immortal Residence with the ghost and flew towards a stone hall in the south of the city.

Regarding this stone hall, the ghost had already noticed it when Duan Chen followed Mu Ye to visit the Phantom Moon Demon City, after all, there were not many buildings in the city that covered such an area as this hall.

Looking from a distance, I saw that on both sides of the gate of this stone hall, there were two giant purple demon fox statues more than ten zhang high.

And under these statues, dozens of fox men and women with handsome faces or beautiful flowers are greeting the monks of all ethnic groups who are coming from all over the world with smiles on their faces.

"Senior, this is the Phantom Moon Auction House opened by the Chamber of Commerce of the Phantom Moon Alliance, and it is strictly forbidden to fight in the auction house, and if you violate this ban, you will not only be killed by the Yuan Infant Demon King who is sitting in the auction house, but also the corpse will be hung outside the auction hall for seven days to set an example. ”

Far away, before he got close to the Phantom Moon Auction House, Mu Ye turned his head and said to the ghost with a solemn face.
