Coming to an alchemy room prepared in advance, Ye Feng placed the Wood King Ding in it, sat down cross-legged, and familiarized himself with the steps of alchemy first.

To refine ordinary pills, the general flame is enough, in the Southern Regions Shenzhou, there is a kind of wood called charcoal heart wood, which has excellent combustion power and a strong flame, which is suitable for refining ordinary pills.

He had already ordered someone to find charcoal wood, which had been cut off by a foot and placed in a corner of the house.

If you want to refine the innate level elixir, ordinary charcoal wood cannot be used, because the congenital level elixir has extremely strict requirements for flames, at least it can only be refined by earth fire, and even strange fire is required, the higher the level of the elixir, the more stringent the requirements for flames are.

An hour later, Ye Feng opened his eyes and took out a lot of low-grade elixirs from the storage ring, the first step was to identify the elixir.

Regarding the knowledge of elixir, Ye Feng is not very profound, and the general elixir can still be distinguished clearly, so he plans to start with Guyuan Dan first.

Refining Guyuan Dan can generally be done by more than a dozen kinds of elixirs, it is not very complicated, it is basically a big road goods, and it is not very difficult to refine, and an alchemist with a little alchemy qualification can complete it, to put it bluntly, this is an apprentice-level elixir.

After gathering the materials of Gu Yuan Dan, Ye Feng took a deep breath and ignited the charcoal wood, a vigorous flame appeared, and the wood king tripod was placed on top of the flame, and when the flame burned the wood king tripod, a faint fragrance appeared.

"This Mu Wang Ding is really a good thing, it can exude rosemary by itself, helping alchemists to stay awake at all times!"

Ye Feng felt that his soul had been greatly benefited, and this rosemary could help the development of his soul and keep people awake at all times.

The first elixir was thrown into the Wood King Ding by Ye Feng, and the water in the elixir was quickly evaporated and turned into the shape of powder, and Ye Feng began to produce various handprints and refine them according to the introduction in the Golden Book of Heaven.

The main purpose is to reject the impurities in the elixir, any elixir, there are impurities in it, only through the guò technique, the impurities can be cleaned out, and the rest is the essence.

Ye Feng's technique is very strange and unique, if there is a real alchemy master who sees it, he will definitely be surprised, Ye Feng is going to be a anyway method, while refining the elixir, he produces all kinds of handprints, and even a trace of soul inscription in it, Ye Feng is a three-pronged approach.

Refining the elixir is to repel impurities and make hand prints, which is to make the medicinal properties of the elixir come into better play, and the soul inscription technique is to improve the quality of the elixir.

The first two are not difficult to understand, ordinary alchemy masters can do it, but like Ye Feng, an alchemy rookie, can be distracted and used for three purposes, which is not normal.

For ordinary alchemy apprentices, it is already good to be able to repel impurities, and as for sealing to improve the quality of the elixir, at least it needs to reach the level of an innate level alchemist.

The first elixir was quickly decomposed, and a crystalline water droplet appeared, which was the essence of the elixir's compression.

The second, third, fourth......

With the successful extraction of the elixir essence from the first plant, Ye Feng's technique became more and more proficient, and in the blink of an eye, more than a dozen elixirs were stripped of by Ye Feng, and the essence inside was stripped out.

The second step, Rong Dan!

According to the introduction above in the Golden Book of Heaven, Ye Feng began to step into the second procedure, fusing more than a dozen elixirs into a pill, which required precise control, not as simple as casual fusion.

Whoever comes first and who comes last, there is a strict control, and the time cannot be wrong, once it is wrong, the entire elixir will be scrapped, and it may even be fried.

The medicinal properties in the elixir are very terrifying, if the acquired martial artist swallows the best elixir, he can directly support the body, and the same is true for refining the elixir, the energy in the elixir is too terrifying, once he is not careful, the elixir will go berserk and directly lead to the blaster.

The two crystalline drops of water began to fuse, entering the Rong Dan stage, Ye Feng was very careful, and even mobilized all his divine souls to watch every move in the Mu Wang Ding, not daring to relax in any way.

It was very smooth, the two drops of crystal water beads successfully fused, and it was a good start, and then it was more smooth, the third drop, the fourth drop, Ye Feng strictly followed the procedure in the Golden Book of Heaven, and did not dare to make a mistake in one step.

A stick of incense passed, and ten drops of crystal water successfully fused into a dark green oval elixir the size of a quail.

The last step is to polish and refine the oval-shaped dark green pill into a pill.

There are more techniques, Ye Feng surrounds the Muwang Ding, and hundreds of handprints enter the Muwang Ding, infiltrating into the pills that have been formed, if the techniques are wrong, the pills will be scrapped, and they may become waste pills.

Because it was the first time, Ye Feng could only refine one Guyuan Dan, if he was proficient, he could refine five or six at a time, a real alchemy master, and even could refine dozens of Guyuan Dan at a time.

As everyone knows, Ye Feng has deviated from the path of alchemy, even according to the introduction in the Golden Book of Heaven, he has also deviated from the trajectory.

Ten elixirs, at the very least, can also refine five Guyuan pills, ten crystalline droplets of water can decompose five parts, but Ye Feng fused them together and turned them into a pill, this is the strength of Dan Chenzi, a great alchemy genius in the cultivation world.

Although the number of pills decreased, the quality of the pills increased by five times, turning the medicinal properties of the original five pills into one pill.

An hour passed, the pill gradually shrank, and a faint medicinal fragrance appeared, and a dragon's eye sized pill made a dripping rotation in the Mu Wang Ding, and the faint medicinal fragrance came from here.

There is still one last step left, Cheng Dan.

The last step is relatively simple, mainly to control the stability of the pill, and to collect the fire in time, it seems to be a complete pill, once the fire is not careful, it is possible that the pill will break, and it is also possible that the spirit of the pill will be lost.

"Close!"

Ye Feng suddenly let out a low snort, all the flames of the charcoal heart wood were extinguished, the wood king Ding let out a humming sound, and the formation inside began to stop working.

After the charcoal heart fire was extinguished, Ye Feng didn't rush forward, feeling tired for a while, he didn't expect that refining the pill would consume soul power so much.

After a short period of recovery, Ye Feng walked in front of Mu Wang Ding and saw a crystal clear elixir appear, emitting a treasure light.

"The best Guyuan Dan!"

Ye Feng was taken aback, generally the highest quality of Guyuan Dan is also the highest grade, as for the best product, it is simply impossible, because of the limitation of materials, it is the limit to be able to refine the top grade.

And this pill in front of him is already infinitely close to the innate level, the only thing that does not meet the standard is that the elixir level is not enough, if you add a superb elixir, it is completely possible to raise the grade of Gu Yuan Dan to the innate level.

"How is this possible, is it because I joined the Soul Inscription Technique?"

Thinking that his soul inscription technique could improve the level of the elixir, Ye Feng was also relieved.

"How about trying it out!"

Swallowed Gu Yuan Dan in one gulp, turned it into a liquid of glycol, and entered Ye Feng's body.

"Five times the energy of the Gu Yuan Dan!"

Ye Feng was shocked again, this Gu Yuan Dan was not only of high grade, but even five times the energy, which was simply incredible.

"It seems that I have really picked up the treasure, I didn't expect the alchemy of Danchenzi's predecessors to be so powerful!"

Ye Feng was not so enthusiastic about alchemy just now, when the Guyuan Pill appeared, Ye Feng had a great desire for alchemy, if I could refine a large number of spiritual pills, why worry about my strength not improving.

An alchemist, can create a sect, and even prosper for a thousand years, if there is no extraordinary ability, it is impossible to gain a foothold, Danchi Sect is famous by relying on alchemy, and there is a steady stream of genius disciples, who have been extremely popular for a while, if it is not coveted by other sects, it will not fall to the fate of being exterminated.

Even if it was the Wannian Sect, it did not develop as rapidly as the Danchi Sect, at that time, Danchenzi was known as the ancestor of the Ghost Pill, and his alchemy took a strange route, and the medicinal properties of each pill exceeded common sense.

In the following time, Ye Feng never gave up, kept experimenting, and kept refining new pills.

"Zengyuan Dan, Guyuan Dan, Peiyuan Dan, Washing Pulp Pill, Strengthening Bone Dan......"

One pill after another appeared, each of them was five times the energy, but unfortunately it was all an acquired elixir.

A day later, Ye Feng finally felt tired, and he continued to cast the Soul Inscription Technique, which was a great test for Ye Feng's soul power.

"It seems that I'm going to try the innate level elixir, the ordinary acquired elixir, no matter how much I refine, it won't be of any use to me!"

The technique was proficient, and Ye Feng planned to try the innate level elixir.

He took out ten ordinary elixirs, one top-grade elixir, and three auxiliary elixirs, which were the materials for refining the Innate Pill.

An innate pill, if swallowed nine times the day after tomorrow, can increase the chance of breaking through eighty percent, and it can be regarded as the lowest innate level pill.

Taking a deep breath, refining an innate level pill is dozens of times more difficult than an ordinary pill, the level of the elixir is increased, the medicinal properties are also strong, and refining is even more cumbersome.

After resting for a cup of tea, Ye Feng restored all his souls, lit the charcoal heart wood, and prepared to refine.

The early stage was very smooth, the elixir purification was very good, Ye Feng was even a little secretly complacent, refining for a day, except for one failure, it was basically successful.

Soon entered the second step, the procedure of Rong Dan, fusing more than a dozen elixirs together.

"Bang!"

When the two different elixirs were combined, a muffled thunder appeared, emanating from the inside of the Mu Wang Ding, followed by a puff of green smoke.

"Failed!"

Ye Feng was a little puzzled, there was no mistake in the steps of his own refining, why did the phenomenon of fried pills appear.

"I understand, the reason for the charcoal core fire, its temperature can't meet the requirements of refining the Innate Pill!"

Ye Feng quickly found the reason, it was on the charcoal wood, the flame concentration of ordinary charcoal wood could not meet the requirements of the innate pill, so the phenomenon of fried pill appeared.

After understanding, Ye Feng gave up continuing refining, and wanted to refine the innate level elixir, there was only one way, to find the earth fire.

And the place that has earth fire, in Ye Feng's impression, only the Danguan of the Heavenly Spirit Academy has it.

A day later, a thin old man entered the realm of Da Luo Academy, and soon flew into the main peak, passing through a layer of ripples, and entering the main hall.

"Qiyu Courtyard Master, the mission has failed!"

The thin old man looked at the master of Da Luo Courtyard with a look of helplessness on his face.
