Activating the Dan furnace and observing the incense kung fu, Xu Chen almost understood the formation and the steps of alchemy inside, and the next thing is to actually operate it by hand, get some herbs and try a few furnaces to see the effect.

Of course, don't think about the elixir, you can only get some ordinary herbs to refine some vandan first.

Now that the medicine garden has been destroyed, the elixir and spirit grass for refining the elixir in the mountains and fields near Taiyuan Gate will definitely not be available, so Xu Chen put away the Dan furnace and went down the mountain.

An hour later, he returned to the hut and poured out a large mess of medicinal herbs from his storage bag.

For the disciples of the Immortal Sect, these medicinal materials are completely garbage in the garbage, and they don't have the slightest aura.

But if you get to the mortal realm, everything is worth a lot.

Ten-year-old Dancao, 20-year-old Radix Radix, 30-year-old Blood Mushroom, 100-year-old Polygonatum Polygonatum and so on, as well as a variety of dangerous medicinal herbs such as poisonous insects and snakes that only grow on steep cliffs and even deep in caves.

These things are everywhere in the deep mountains and dense forests near Taiyuan Gate, but for folk mortals, they need to face great danger and even pay for their lives to pick them.

Xu Chen checked the jade slip, slowly found seven kinds of medicinal materials from it, and placed them on the stone slab one by one.

There are only two kinds of Fan Dan that Xianmen refines on weekdays, one is Qingshui Dan, which is used to cut hair and wash the marrow, and the other is Peiyuan Dan, which is used to open up the meridians.

However, Pei Yuan Dan already has a hint of elixir aura, and one or two of the medicinal materials are not easy to find, so Xu Chen will definitely not be able to make it up at the moment, so he can only practice with Qingshui Dan first.

After the preparations were completed, Xu Chen activated the Dan Furnace again, and carefully looked at the method of refining the Qingshui Dan again, and then put a hand on the Yuan Qi channel of the Dan Furnace, continuously inputting the Yuan Qi, and using his divine sense to impact the fire gathering formation at the bottom of the furnace.

Soon a wisp of blazing white flames burned in the Dan furnace, and when he felt that the fire was almost over, he threw the collected medicinal materials into the Dan furnace in the same order as alchemy.

There are two ways to refine the elixir, one is to use the monk's Yuan Spirit Qi to ignite the furnace fire for refining, and the other is to put in spirit stones as fuel.

Generally speaking, refining the spirit pill will definitely put spirit stones, but this is just a furnace of fan pills, and it is not used at all.

Xu Chen was confident that a furnace of Qingshui Dan would be a piece of cake for himself.

After several medicinal materials entered the Dan furnace, the lid of the furnace was closed, and under the traction of the divine sense, these medicinal materials were wrapped in different formation lights and shadows according to the attributes of the five elements for calcination, and finally the useless ingredients in them were burned into ashes, leaving behind the essence of the synthetic pill.

Xu Chen felt very relaxed during the entire refining process, even if he was a little hurried in the middle and even almost made a mistake, he still took the Danfang Jade Slip to read halfway, but in the end, he successfully refined all the medicinal materials at one time.

The next step is Hedan, this step is particularly crucial, if it goes wrong, all the medicinal materials will be destroyed.

The more precise the control of the process of Hedan, the more uniform and suitable the composition of the pill, and the better the effect of the pill.

Fan Dan does not have too detailed requirements for Hedan, generally speaking, it is so-so.

However, Xu Chen was still very careful, after all, it was the first time to make alchemy, and he was actually a little excited in his heart.

He didn't expect that he would successfully refine all seven medicinal materials at once.

He had also heard Senior Brother Jiu talk about how hard alchemy was, how it consumed divine energy, and how troublesome it was, especially in the refining stage, so many medicinal materials had to be baked and refined one by one according to different methods and different formations and temperatures, and in order to retain the maximum medicinal effect, there must be no careless mistakes and so on.

But today, it seems that Senior Brother Nine is exaggerating a little.

Xu Chen was a little disappreciative in his heart, but in fact, he forgot the reason why the powerful divine sense he brought to him after he had an extra blue jade bead in his head made him so relaxed.

Cultivators who have started to practice Qi can refine things like Fan Dan, but it is just a matter of the success rate and the number of pills.

In the late stage of the Kaiyuan Realm, it was really easy to refine the First Rank Pill, but for the Second Rank Pill, it was still very difficult.

Like Senior Brother Jiu, although he has reached the late stage of the Kaiyuan Realm, he has not mastered the skills of refining Yipin Dan until now, and he can still only refine the Mortal Dan such as Qingshui Dan and Peiyuan Dan.

In addition, he can also refine Xiao Yuan Dan, but because of the preciousness of the medicinal materials, it is rare to refine it several times a year, and there is a high chance of refining it during the period, so the level of this alchemy is naturally a mess, and there is no way to grow quickly.

If it is in a large immortal sect, the low-end elixir is sufficient, and the natural alchemy apprentice will have a large number of medicinal materials to practice, and the level of alchemy will increase rapidly, and he may become a qualified first-grade alchemist in half a year and a year.

But for Taiyuanmen, the growth of disciples is too difficult.

It is far worse to spend time on alchemy, not to mention going down to the mountain to practice and rob.

This is also the reason why Senior Brother Jiu is reluctant to do alchemy on the mountain.

Xu Chen's divine consciousness was fully immersed in the Dan furnace, and it was the critical juncture of Hedan.

In the center of the Dan furnace, accompanied by a spiral formation, a faint whirlwind of Yuan Force began to whistle and rotate, and the seven kinds of medicinal materials that had been refined fell like a whirlwind under the traction of his divine sense, and finally mixed together, after more than ten breaths, waiting for the whirlwind to slowly stop, a gray plaster appeared in the center of the Dan furnace, and then the divine consciousness continued to activate the Dan formation, and soon the plaster was decomposed into more than ten mud balls of uniform size, and then the whirlwind rose again, and these mud balls swirled in the whirlwind, and soon became a projectile the size of a mung bean.

The final step is to raise the Dan and come out of the Dan.

However, for Fan Dan, raising Dan is basically saved, and this thing is still Fan Dan if it is kept in the Dan furnace for a year, and there will be no trace of spirituality, so Xu Chen urged the furnace fire to roast the pill, and gently patted the Dan furnace, the lid of the furnace popped open, and more than ten gray pills rose out with a thick medicinal fragrance, and were taken into his hand by a roll of vitality.

Xu Chen took the freshly baked pill and looked at it carefully, and found that the size was uniform, the medicinal fragrance was rich, and the color seemed to be much better than the Qingshui Pill that Senior Brother Nine had when he went down the mountain, with a hint of grayish luster.

"Woo ......"

Smelling the fragrance of medicine, the little fox excitedly jumped on Xu Chen's lap and called.

Xu Chen directly pinched one and stuffed it into the little fox's mouth, and he couldn't help but knock one on it, and then smacked his mouth, and found that except for a medicinal fragrance, there was no effect, not even jelly beans.

Xu Chen's face was full of regret and put the remaining Qing Shui Dan into a small porcelain bottle.

Then the second furnace began.

This time, the alchemy process is much better and faster than the first furnace, and it is only two moments before and after, and it is time for Hedan again.

Xu Chen's original purpose was to test to see if he could integrate the white qi released from the jade bottle in the sea of consciousness into the elixir, so when he was in Hedan, he was engrossed in using his divine sense to probe into the jade bottle and touch the jade bead, and then released the idea of wanting to draw out the white qi.

Although he didn't get any similar feeling of resistance or cooperation from the jade bead, under the touch of this consciousness, Xu Chen actually felt that a wisp of white qi released from the mouth of the jade bottle actually appeared in the Dan furnace along with his divine sense.

Xu Chen was overjoyed, and said in his heart that it was indeed an immortal weapon, and it could really be communicated with consciousness, so he used his divine sense to pull this wisp of white qi and try to integrate it into the medicinal mud.

However, at the moment when the white qi fused, a mass of gray mud that had been fused was instantly ignited by the spiritual fire, and it was completely burned into ashes in just two breaths.

Xu Chen had no choice but to activate the formation to clean up the Dan furnace, and after discharging the ashes from the bottom of the furnace, he conducted the third alchemy test again.

However, the next two times in succession, they were unable to integrate into the white qi when they were in Hedan, resulting in the failure of alchemy.

So Xu Chen knew that maybe it was because the level of Fan Dan was too low to fuse with Bai Qi.

Or maybe this white qi can't be integrated into the elixir at all.

But he still didn't give up.

If the pill can't work, maybe the elixir can.

Therefore, he began to think about where to get some high-end medicinal materials to try refining a furnace of Xiao Yuan Dan.

Although Xiao Yuan Dan has not yet been introduced, after all, it is an elixir containing aura, which can barely be regarded as a elixir, and the materials are not particularly precious, even if one or two furnaces are refined, they can still bear it.

Just as Xu Chen was scratching his ears and cheeks to find a way, a cyan light came from Chaoyang Peak and landed in front of the cabin in an instant.

"Senior sister, why are you here?" Looking at Zhao Xuan, who had collected his sword and landed on the ground, Xu Chen quickly stood up and saluted.

Zhao Xuan's cheeks flushed slightly, and she twisted: "It's not an outsider, junior brother doesn't need to be polite!" ”

Xu Chen touched the back of his head and said with a dry smile: "I'm used to it, I don't feel like a formal greeting if I don't make a gesture." ”

"Hee-hee, you're obviously perfunctory!" Zhao Xuan covered her mouth, then smelled the medicinal fragrance that was still wafting in the air, looked at the Dan furnace on the ground and said, "I just heard from Senior Brother Jiu that you want to learn alchemy, and you want to leave his Dan furnace, I specially came to see what kind of Dan you can refine." ”

Xu Chen's cheeks twitched: "I think it's good to learn alchemy, but the Dan furnace was forced to me by Senior Brother Nine!" ”

Zhao Xuan was stunned for a moment, and couldn't straighten up with a smile, and said with crooked eyebrows: "I just feel that something is wrong, it turns out that he wants to throw the task of alchemy to you." ”

Xu Chen was also stunned, and said with a strange face: "What alchemy task?" ”

Zhao Xuan said with a smile: "You don't know yet, Senior Brother Nine has already gone to the Third Elder and said that you want to learn alchemy, and I want you to take over him to the Dan Academy to follow the Third Elder for alchemy, and he will be able to go down the mountain at any time in the future." ”

Xu Chen's face suddenly darkened, but in the end, he could only smile bitterly: "It seems that Senior Brother Jiu has been waiting for this opportunity for a long time, and I am the only one who has thrown himself into the net." ”

Zhao Xuan nodded: "It's not, but it's not bad for you to learn alchemy, junior brother, I can help you when the time comes, in fact, I'm also quite interested in alchemy, and occasionally I go to the Dan Academy to help the three elders sort out the medicinal materials." ”

"That's just right, senior sister, take a look, this is a furnace of Qingshui Dan that I refined today, it seems to be pretty good!"

Xu Chen handed over the Qing Shui Dan on the stone, Zhao Xuan took the medicine bottle and pouted: "It's just a furnace of Fan Dan......

However, when she poured out a pill and looked at it, her face instantly became extremely surprised, and she said, "This is what you just refined, junior brother?" ”

Xu Chen nodded and said, "Freshly baked, it's still hot!" ”

The smile on Zhao Xuan's face at this time had become a lot more serious, feeling the residual warmth and medicinal fragrance emitted by the pill, and after carefully looking at it one by one, he said: "Although Qingshui Dan is a Fan Dan, it is still not easy to refine it so well, I have also refined some Qingshui Dan before, but it is far inferior to you." ”

Xu Chen shook his head and said, "It's just a pill, what's the use, senior sister took the time to help me collect some medicinal materials for refining Xiao Yuan Dan, I want to try it." ”

Zhao Xuan nodded and said: "Okay, but although Xiao Yuan Dan has not entered the product, it is much more difficult than Fan Dan, and there are a few medicinal materials that are also difficult to find, and it is a little distressing to practice and waste." ”

Xu Chen said helplessly: "Then what can be done, since you want to learn, then no matter how difficult it is, you have to practice, otherwise, like Senior Brother Jiu, you can't refine a furnace of spirit pills in a few years, so it's better not to learn." ”

Zhao Xuan covered her mouth and smiled: "Don't say it, Senior Brother Jiu doesn't know where to hide now, I still have a few medicinal materials for refining Xiao Yuan Dan, I'll get them for you later, other senior brothers and sisters should have more or less some, maybe I'll get them for you in a while." ”

Xu Chen's eyes suddenly lit up and said, "Why didn't I think that we would go to find other senior brothers and sisters." ”

Zhao Xuan nodded, then slightly twisted and took out a thumb-sized green jade bottle from his arms and handed it to Xu Chen, "Little junior brother, this bottle of spiritual liquid is for you." ”

Xu Chen was stunned for a moment and shook his head and said, "How can this be, the three of us divided the ...... at the beginning."

"I'll take it for you, I can't go down the mountain now, maybe I'll stay on the mountain for a few years to recuperate, it's a waste to leave such a good thing on me, you have used it last time in the Linghu Mine, and you can still use it when you go down the mountain in the future."

Looking at the jade bottle that was forcibly stuffed into his hand and feeling the residual temperature on it, Xu Chen thought for a while and put the spiritual liquid into the storage bag and said, "That's fine, when I get the spiritual liquid next time, I will return a big bottle of senior sister!" ”

Zhao Xuan immediately smiled with crooked eyebrows: "What you said, don't forget when the time comes, let's go!" ”

"Good!"

As they spoke, they threw out their flying swords and took off to the top of Chaoyang Peak.
