Chu Duan said that he was in retreat in the Great Black Palace, but in fact, he actually entered the Qifu Cave Heaven and refined the pill in the attic in the original Phalange Cave Heaven space. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoThis attic was moved by Chu Duan from the Phalanx Cave Heaven to his own Qifu Cave Heaven, the attic has three floors, and the first floor is the place for alchemy.

This layer was laid down by the Evil Medicine King Nine Dragons Gathering Fire Array, this is a Dao Rank Upper Grade Formation, with extremely terrifying power, the Evil Medicine King has been refining all kinds of precious Dao Rank Pills with the help of this formation.

The Dan furnace used by Chu Duan was still the Black Dragon Furnace, the natal magic weapon of the Evil Medicine King, according to Huo Lao, this Black Dragon Furnace was originally a medium-grade Dao weapon, but with the failure of the Evil Medicine King's alchemy and falling from the Cave Heaven Realm, the spirit of this Dao weapon was also extinguished, and the grade fell.

Previously, this Black Dragon Furnace was only equivalent to a spiritual weapon, but Chu Duan repaired the partially damaged prohibition in the Black Dragon Furnace under the guidance of Huo Lao, and now it is already an excellent low-grade Dan furnace. Don't underestimate the Dan furnace of the lower grade of the excellent treasure level, among the various magic weapons, the alchemy furnace and the refining furnace are the most precious, and they are often much more valuable than other methods of the same grade.

The reason why it is valuable is because magic weapons such as alchemy furnaces and refining furnaces require more effort and more precious mineral materials to refine, which is far greater than the consumption of other magic weapons of the same grade, and naturally it is more precious.

At that time, the Evil Medicine King was known as the immortal Dan Dao Gai Dai Tianjiao of the Dan Immortal Palace, and he almost had the reputation of being the first Dan Dao Grand Master in the world at that time, and there were countless big people who begged him to make alchemy.

At that time, the Evil Medicine King had unimaginable resources in his hands, and he only raised his natal magic weapon, the Black Dragon Furnace, to a medium-grade Dao weapon, but in terms of value, it was much more precious than an ordinary high-grade Dao weapon.

The current Chu Duan is rich and rich, and he has placed ninety-nine eighty-one high-grade soul jade on the eye of the Nine Dragons Gathering Fire Array, and one high-grade soul jade is equivalent to one hundred medium-grade soul jade, which is converted into ten thousand lower-grade soul jade.

There are not many jade essences and blood jade in the underworld, each accounting for only two percent of the production, while soul jade accounts for as much as sixty percent. Now that the Bugui Mountain Range is all owned by the Heaven Destroying Sect, there is an underworld monk Yin Chuan who is good at finding what kind of mineral veins, and many of the mineral veins buried underground cannot escape his exploration.

The Nine Dragons Gathering Fire Array was instilled with the power of the soul jade, and a fiery red dragon shape with a length of three zhang emerged, and condensed between breaths, as if a real fire dragon had descended, exuding hot power.

The Black Dragon Furnace floated in mid-air, and all kinds of medicines fell into the furnace under Chu Duan's control, and the Nine Dragons Gathering Fire Array's Array Spirit Dragon Treasure came out of the formation to assist Chu Duan in controlling the formation to refine the elixir.

Chu Duan's refining this time was Bao Dan, although it was only the easiest Jade Chen Dan to refine in the lower grades of ordinary treasure ranks, but Bao Dan was Bao Dan after all, and it was like a cloud of mud with the spirit pill. There are twenty-two kinds of medicinal materials required for Yuchen Dan, of which the main medicine is Yuchen Grass, which is the lower grade of the ordinary treasure level, and the other twenty-one medicinal materials are all pseudo treasure ranks.

The mature jade grass is about two feet high, and the oval leaves seem to be carved from jade, exuding a faint fresh smell. There are inconspicuous rune lines on the surface of the leaves, and there is a turquoise glow circulating.

Yuchen grass fell into the black dragon furnace, and it didn't take long to be refined to get the required medicinal power, warm furnace, refining, and Hedan, which are the three major steps of alchemy, and each of them can be divided into many small steps. Chu Duan started from the warm furnace, to refining the medicinal power, and then to the final Hedan, all in one go.

In this process, Chu Duan's spirit was highly concentrated, his hands changed dozens of times between breaths, and he constantly pinched out the seal and punched it into the black dragon furnace. The impurities in the medicinal materials are refined, leaving only the required medicinal properties, and the last step of Hedan is even more sloppy, otherwise the previous efforts will be wasted.

Hedan is the last and most difficult step in refining the elixir, because the medicinal properties of the various herbs are different, and some even conflict. If the conflict between the medicinal properties cannot be reconciled, the quality of the pill will be reduced, or even the waste pill will be refined, and the worst will directly cause the fryer.

The fryer is definitely the nightmare of all alchemists, and it was because of the fryer that the Evil Medicine King fell to the altar, not only was he hit hard, but he even fell into the Cave Heaven Realm.

Chu Duan carefully reconciled the medicinal properties of various medicinal materials, allowing the medicinal properties to merge together to synthesize the final Yuchen Pill. As Chu Duan's last seal entered the Black Dragon Furnace, the Black Dragon Furnace let out a soft "hum", and the emerald green light rose from the Black Dragon Furnace.

The sound of "bang, bang, bang" came from the Black Dragon Furnace, like gold hitting jade, as if something was hitting the Black Dragon Furnace.

Chu Duan stepped forward, and the black dragon furnace slowly landed, only to see more than a dozen emerald green light clusters of different shades of color flowing with jade luster in the furnace constantly beating, wanting to fly out of the black dragon furnace. It's just that now the Black Dragon Furnace is an excellent low-grade Dan furnace, and the invisible power envelops the furnace mouth, and it can't escape even if the light group hits.

"Bad guys, let us go. ”

"Please, let me out. ”

"If you want to eat them, eat them, I'm not delicious, let me go." ”

The sound of chirping came from more than a dozen light clusters, and the noisy people had headaches and made people upset. If you can see through the light cover outside the light cluster, you can find that each of these dozen or so light clusters has a pill wrapped in the center, and that is the Yuchen Pill.

"It's noisy!"

Chu Duan grunted, pinched out the seal recipe in his palm, and directly entered the black dragon furnace, and the light transformed by the seal trick fell on more than a dozen light clusters. More than a dozen light clusters quieted down, and the brilliance on the surface converged, manifesting a jade Chen Dan that was as round as a dragon's eye.

Huo Lao came out of nowhere, saw the seal that Chu Duan pinched out, and sighed: "The existence named Dan Weng who led you into the Dan Dao, I am afraid that the origin is unimaginable, you can comprehend such a powerful method of forbidden spirits from the Dan Dao he taught, it can be seen that Dan Weng's Dan Dao attainments have already been cultivated." ”

Chu Duan rolled his eyes and said, "That's also my extraordinary talent, okay, otherwise ordinary people wouldn't be able to comprehend it." ”

What Chu Duan just performed was the method of forbidden spirits that he had learned from the Tongtian Dan Dao taught by Dan Weng, and the so-called forbidden spirit method was to imprison the spirituality of the elixir, seal the spirit of the elixir into the elixir, and improve the medicinal power of the elixir.

Huo Lao pursed his lips and did not pierce Chu Duan, but went to observe the dozen or so Jade Chen Pills that Chu Duan had just refined. After counting carefully, there are a total of fourteen Yuchen Pills, of which there are two Yuchen Pills of perfect quality, five of them are of the best quality, and the remaining seven are all Yuchen Pills of high quality.

"I don't know what kind of luck this kid has taken, and he can actually refine a perfect quality pill, this is a skill that countless alchemists can't ask for!" Huo Lao secretly scolded himself.

Chu Duan was a little dissatisfied when he saw that there were only two perfect quality pills, and said, "I actually refined two perfect pills." ”

Huo Lao said angrily: "The first attempt to refine the Bao Dan can be successful, and the fourteen pills are refined in one furnace, the lowest are high-grade pills, you kid is not even satisfied, if other alchemists know, you have to wipe your neck in shame and commit suicide." ”

Chu Duan heard the sourness in the old words of the fire, and also felt a little embarrassed, touched his nose and smiled without saying a word.

The successful refining of the Treasure Rank Pill marked that Chu Duan's attainments in the Dan Dao had crossed a hurdle and he had been successfully promoted to become a Dan Dao master. Even if he is only a junior Dan Dao master, the Dan Dao master is the Dan Dao master, and he is a completely different level from the Dan master.

Any Dan Dao master has an extremely high status in the cultivation world, and even the giant clan and the emperor clan cannot be humiliated. Many alchemists practice Danshu hard, often taking hundreds of years to become a Dan Dao master, and any alchemist who achieves a Dan Dao master within the age of 100 is well-known in the cultivation world.

And how old is Chu Duan now? He is not yet fifteen years old, and he is only fourteen years old, and he is still a teenager. This has almost never happened in the cultivation world, even when the Evil Medicine King became a Dan Dao Master, he was also over seventeen years old and had already reached adulthood.

After all, alchemy is different from cultivation, and if you have a high talent, you can soar to the sky, and alchemy requires you to accumulate experience in alchemy again and again.

After successfully refining the Yuchen Pill and becoming a Dan Dao master, Chu Duan did not go out of the customs, but continued to refine the Bao Dan. During this time, he devoted himself to studying the Dan Dao, looking through the Dan Dao Codex left by the Evil Medicine King, and consulting the various heavenly and earthly treasures and pill prescriptions recorded in the inheritance jade.
