The alchemy room of the Shendan Hall has an area of only about ten square meters, with a circular platform half a meter high in the middle, and a simple and thick furnace in the middle, engraved with various flower and plant patterns, which looks atmospheric and solemn. Pen, fun, and www.biquge.info

Under the furnace is a faucet mechanism, open it will spew out a scorching earth fire, the mechanism is well-made, painstaking, and the size of the earth fire can be adjusted at any time according to the needs of alchemy when operating, it can be described as ingenious, and the strangeness of the idea is amazing.

Gao Feng stretched out his hand and touched this furnace, although it was only a primary Dan furnace, it was obviously completely superior in materials and texture, for a novice like him, it should be enough to practice his hands. He resisted the urge to take out the intermediate Dan furnace "Gu Yan Baoding" and decided to try it with this ordinary furnace Ding first.

Because he had the alchemy memory and experience of the Ghost Hand Medicine King in his mind, Gao Feng was actually self-taught, so he had to give it a try himself.

Of course, after all, it was the first time to refine the pill, and Gao Feng was not sure, he decided to start with the lowest-level pill refining first, so he collected thirty copies of the herbs of the Shun Ling Pill and the Hui Yuan Dan in the Lingtian, and then came to sit down on the futon next to the furnace in the middle, closed his eyes and muttered a pillar of incense for a while, and carefully recalled the Dan recipe and the refining process of refining the Shun Ling Pill in his mind, and even analyzed every detail carefully, and felt that there was no problem, so he reached out and opened the faucet mechanism.

A scorching earth fire rushed out, instantly enveloping the furnace, Gao Feng was secretly surprised, he couldn't imagine that the earth fire was so fierce, and hurriedly adjusted it to control the flame at a suitable temperature. After about a dozen breaths, the furnace Ding was roasted by the ground fire, and gradually glowed with a faint blue light, and there was a light sound of "hissing" in the air in the Ding, because this Ding is used for alchemy all the year round, and a medicinal fragrance in the Ding wall came with it, which made people feel excited.

This is the first stage of the alchemy step, called the "warm furnace", which is to preheat the originally cold Dan furnace through the earth fire, and only after reaching a certain temperature can the second stage of "alchemy" begin.

Don't look at the first stage of the furnace seems to be very simple, but the temperature of the ground fire of this furnace must be controlled in place, the temperature of the ground fire is too high, it will form a "furnace", if the furnace is refined, the herbs are easy to burn, resulting in too much residue, so that the rate of refining the pill is greatly reduced, and it is a serious direct failure.

When the furnace is too low, it cannot meet the requirements of the furnace, and a "cold furnace" will be formed when refining medicine, and the dissolution rate of medicinal herbs in the cold furnace is very low, which will cause waste of medicinal herbs, and will also reduce the rate of becoming a pill or failing to refine medicines.

Therefore, the first step of alchemy, "warm furnace", is the foundation that every alchemist attaches great importance to, and many beginners often fail because they are prone to make mistakes due to poor control in the first stage.

Gao Feng naturally knew the importance of this step through the memory of the Ghost Hand Medicine King, so he controlled the temperature of the earth fire very carefully, and completed the requirements of the first stage very smoothly.

Smelling the faint fragrance coming from the Dan furnace, Gao Feng knew that the time was ripe and he needed to carry out the second stage of "alchemy". He continued to carefully control the earth fire with his left hand, and with a flick of the sleeve of his right hand, a Yuan Force gently lifted the dosing port on the lid of the furnace, and then the index finger of his right hand was slightly raised, and a medicinal herb flew into the Dan furnace along the dosing port.

According to the secret method of alchemy of the Ghost Hand Medicine King, Gao Feng separated a wisp of divine consciousness, tightly attached to the herb, and flew into the furnace together.

The sound of "Zizi" came in bursts, and as soon as the herbs entered the Dan furnace, they were instantly melted by the high temperature in the furnace, but fortunately, Gao Feng wrapped the herbs in time with his vitality and divine sense, so that he was not instantly baked by the high temperature.

In the Dan furnace, the herb gradually dissolved into a black paste, and under the control of his divine sense, Gao Feng's gray vitality smoothly swam in the paste, and at the same time, the impurities in the medicinal juice were eliminated little by little. Each herb has different attributes like the aura, and the aura that is consistent with the attributes of the herb is the easiest to be accepted by the medicinal juice, and it is easy to remove the impurities, and the aura with different attributes of the herb is extremely difficult to remove the impurities, not to mention that some herbs are multi-attributed, and it is even more difficult to eliminate.

Since Gao Feng was a full-attribute spiritual root, his aura could be fused with any attribute of medicinal juice, and the entire process of removing impurities became extremely simple. It didn't take long for the black paste in the Dan furnace to slowly turn from black to crystal clear, condensed into a drop of white essence.

The corners of Gao Feng's mouth smiled slightly, this step went smoothly, his index finger continued to stir, and the medicinal herbs next to him flew into the furnace one after another and began to refine.

After about two hours, all the herbs needed for the Shun Ling Pill had been put into the Dan furnace, turning into a white liquid the size of a goose egg, and the second step of refining the medicine was completed.

This is followed by the crucial third step, "Fendan", which is based on the amount of dissolved medicinal juice, which is cut into several balls of liquid medicine and condensed into Dan respectively. This process is very critical and very skillful, uneven division, Cheng Dan will be different in size, there will be differences in the efficacy, the ground fire control is slightly poor, and the medicinal juice will also splash at any time and cannot become a Dan. In short, this stage is a great test of the purity of the divine consciousness and the vitality of the body.

Although Gao Feng knew that this stage was very critical, and he also understood the skills of dividing the pill, it was a pity that he was refining the pill for the first time after all, and as a result, the earth fire control was slightly deviated, and in an instant, the sound of "puff puff" came, and the first furnace of medicinal juice splashed in all directions, and it was instantly baked into ashes by the high temperature.

Gao Feng smiled bitterly and shook his head, he couldn't imagine that he had a wealth of alchemy experience in his memory, and the first alchemy still ended in failure.

After adjusting his mood slightly, Gao Feng immediately started the second alchemy, with the lesson of the failure last time, this time it was very smooth, the third stage quickly divided the medicinal juice, and then started the last step "Ning Dan".

Gao Feng took a deep breath, and the vitality of his whole body was continuously poured into the furnace under the guidance of his divine sense, churning and condensing and compressing each pill of medicinal juice. After three hours, the medicinal juice gradually became round and smooth, full and simple, and the pungent medicinal fragrance wafted out from the furnace, and the smell was intoxicating.

Gao Feng understood that this was the rhythm of Cheng Dan who was about to become a Dan, and he didn't dare to be careless. With his left hand, he controlled the ground fire, and his right hand slapped on the Dan furnace again and again, making a muffled sound of "bang bang bang".

It didn't take long for Gao Feng to look happy, his right hand volleyed open the lid in the air, and under the guidance of the vitality, he saw more than a dozen white crystal pills flying out of it one after another, falling into the porcelain bottle that Gao Feng had already prepared.

Gao Feng looked at the Shun Ling Pill that had been practiced for the first time in the porcelain vase with joy, and saw that each grain was about the size of a small fingernail, round and full, and there was no trace of spurious marks on it.

"Huh, why does the Shun Ling Pill that he has practiced by himself seem to be a little different?" Gao Feng took out a few Shun Ling Pills from the Qiankun Ring, and found that the pill he refined was very clean and round, without the slightest trace of spurs, while the Shun Ling Pill he took out was gray, covered with a lot of black lines and spurs.

Gao Feng frowned secretly, he wasn't wrong, right? In his memory, according to the different levels and abilities of the alchemists, the finished pills were divided into four types: primary, medium, high, and top-grade pills, and the colors were also divided into four categories: black, gray, silver, and white according to the number of impurities.

After all, it was the first time for him to refine the pill, so it was impossible to refine the best pill, right? He knew from the memory left by the Ghost Hand Medicine King that the most common pill on the market was the first grade pill, and the middle grade pill was already very rare, and only the big sects and senior monks had the opportunity to take it, and the high-grade pill was even more rare, and no one in the market would take it out for trading, as for the best pill, no one in the world had ever seen it, and even everyone rumored that it was impossible to refine the best pill without any impurities in this world.

Gao Feng himself couldn't believe it, could it be that he had refined the legendary best pill for the first time in alchemy? This is too exaggerated, isn't it? Is his alchemy talent so rebellious?

In order to confirm whether the one he had refined was the best elixir, Gao Feng swallowed and tested the two elixirs respectively, and found that the medicinal effect of the white elixir he refined was at least dozens of times better than that of the gray elixir in the Qiankun Ring, and it was indeed the best elixir.

Gao Feng was overjoyed in his heart, although he couldn't understand why he was able to refine the best pill, but this was a good thing after all, if he sold this pill on the market in the future, it would definitely cause a "madness".

In the next few days, Gao Feng refined twenty-eight bottles of the best Shun Ling Pill and thirty bottles of the best Hui Yuan Dan.

In the last two days, Gao Feng began to try to refine the Yuan Li Dan, the refining process of the Yuan Li Pill was even more complicated, this kind of pill generally required a second-grade alchemist to be able to refine it.

In the Xuanji Continent, the alchemists are divided into nine levels from the first grade to the ninth grade according to the level of alchemy and the level of the elixir, and the Xia Hall master of the Tianluo Sect Divine Pill Hall, who has been alchemizing for two hundred years, has only stayed at the level of the early stage of the fourth grade alchemist and has not been able to break through for a long time.

And Gao Feng was a beginner, and it was indeed too difficult to refine the second-grade pill suddenly, and the result can be imagined, Gao Feng failed several times in a row, and in desperation, he took out the intermediate Dan furnace "Gu Yan Baoding" of the Ghost Hand Medicine King to refine, hoping to improve a certain success rate, and after several consecutive failures, he finally succeeded in refining a bottle of the best Yuanli Dan.

Seeing that the ten days were about to expire, Gao Feng used a water spell to freshen up a little, and then walked out of the alchemy room satisfied.

At the gate of the Divine Pill Hall, Xia Changqing, the master of the Divine Pill Hall, had been waiting for a long time, and he looked coldly at Gao Feng who was walking from afar, and the corners of his mouth showed a trace of disdain.
