Lingyun Peak is the main peak of the Elixir Mountain, 1,200 meters high, but the Danfang is not on the top of the peak, but in the belly of the mountain.

There are eight secret rooms of different sizes in the belly of the mountain, and each secret room has the introduction of earth fire, but the firepower of the earth fire cannot meet the needs of alchemy, and the alchemist must input vitality in order to mobilize more firepower, and if you want to practice makes perfect, you need to figure out for a long time to accumulate enough experience.

After introducing the infrastructure of the Dan room to Chen Cheng, King Dan took him to the largest secret room, where King Dan put his hand on the side of the entrance and sent a piece of vitality to the round stone ball, the stone door slowly closed, and the secret room could no longer hear the slightest noise except for the sound of the fire.

King Dan took out a furnace of elixir and placed it in order, two of which were provided by Chen Cheng, looking at the elixir in front of him, King Dan sighed with emotion: "Look, it is the same elixir, but the aura contained in these two strains of you is much stronger, as long as there is a good environment, why worry about not having a good elixir!"

"Is it true that the richer the heaven and earth aura contained, the higher the quality of the elixir?" Chen Cheng asked casually.

"Yes and no," King Dan shook his head and said, "The materials, the experience of the alchemist, and the heat of the Dan Fire are all key factors that determine the quality of the medicine, and they are indispensable, and neither of them can achieve a high-quality pill." ”

Although it was the first time to refine the Hundred-Year-Old Pill, the Dan King was not nervous at all, and every step of the warm-up and addition of medicine was easy, which showed how important many years of alchemy experience were.

King Dan had no intention of hiding his secrets, and found that Chen Cheng frowned or showed a puzzled look. will explain to him, one is patient in teaching, and the other is serious in learning. During this period, there were also places where Chen Cheng needed to contribute, such as fire control.

According to King Dan's needs, Chen Cheng had to adjust the size of the firepower at any time, and the fire spirit only listened to Chen Cheng's command, and King Dan had no way to control him.

As long as he learned to control the fire, it would be of great help to him in his future alchemy, and during this period, King Dan also taught him the skills of alchemy, and it took five hours to refine a furnace of pills. King Dan was tired enough, but Chen Cheng benefited a lot, and he didn't feel that time had passed.

No wonder King Dan is sure enough. His experience is enough to make up for the shortcomings in other aspects, if there is a better spirit grass, the commitment rate of ninety percent can be fully guaranteed, and even reach ten percent. This level is rare in Hopeless. Only a very small number of Dan masters can do it.

The first furnace of the Hundred-Year-old Pill harvested six pills, the particles slightly larger than peas, round and shiny, and his heart was full of envy, I don't know how long it would take for him to reach this level.

Although the elixir is good, the aura contained in it and the elixir that Hopeless Star has seen are still slightly insufficient, it is entirely because the elixir is not up to standard, Chen Cheng suddenly thought of a question. I couldn't help but ask, "King Dan, please ask a question." If you add spirit stones to the elixir when you condense the pill, will it improve the quality of the elixir?"

King Dan shook his head with a smile and said: "This idea has been mentioned a long time ago, but if you think about it, the spirit stone is extremely hard, it is difficult to achieve precise control, and most of the spirit stones contain impurities, even if they become pills, there are also very heavy erysipelas, which need to be taken regularly to resolve the poison pill, but the high-grade poison pill has long been unable to refine ......"

Taking advantage of the time to rest in the middle, Chen Cheng raised a lot of questions, and King Dan answered them one by one, and after his body recovered to his best state, he began to refine the second furnace of pills, and had a successful experience, this time not only was the speed half an hour faster, but also miraculously refined nine hundred-year-old pills.

Two furnaces of pills are already a very fatal thing for King Dan, and he must go to rest, but Chen Cheng is mentally abnormal, and he has learned a lot of practical knowledge from King Dan, and he is itchy for a while and wants to refine one or two pills to consolidate and deepen his memory.

"King Dan, uh...... Can I stay here alone, I want to see if I can master it today, you see......" Chen Cheng said in a hesitant manner.

"What's wrong with that, you just have to stay here, but don't waste the elixir, it will always be useful to stay. ”

No matter how much elixir Chen Cheng has, King Dan will not be blushing, but he is inexperienced, if he uses such a good elixir to practice his hands, it is purely a tyrannical thing, so he has to remind him loudly.

"I'm not refining a hundred-year-old pill, I'm just consolidating my newly learned skills, and I'm only refining one or two furnaces of Peiyuan Dan. Chen Cheng hurriedly explained.

King Dan breathed a sigh of relief, "That's good, if my elixir mountain disciple has half of your talent, he can be regarded as a successor......!"

With King Dan's current age, it is no surprise that he only has a lifespan of more than thirty years, and if no one in Elixir Mountain takes the place of King Dan, it will inevitably decline in the future.

Chen Cheng was puzzled and said: "There should be two disciples of the Great Perfection of Qi Cultivation in the Elixir Mountain, Zhang Wangyue has entered the medicine garden with me, his talent is not much stronger than mine, but he just lacks a chance, give him enough time, why should you worry about having no successor?"

"Zhang Wangyue!" King Dan shook his head and smiled bitterly: "His cultivation talent is indeed first-class, but the level of alchemy is several grades behind, and there are not many people who are higher than him among the senior brothers." ”

In order not to affect the rest of King Dan, Chen Cheng did not pester other questions, and it was also a good choice to take advantage of the time for everyone to find Liu Zizi in the past two days, and to study the way of alchemy.

When King Dan left, he took away a hundred-year-old pill, but left the Dan furnace to Chen Cheng, a high-grade spiritual weapon, which was already a rare thing in the earth cultivation realm, but compared with the Dan furnace that Chen Cheng obtained in the Qinling Cave Mansion, it was still one level worse.

Chen Cheng was already in the middle stage of foundation building, so there was no need to be afraid of wolves and tigers like before, he still decided to use his own Dan furnace to refine a furnace of Pei Yuan Dan, and it was an enhanced version of Pei Yuan Dan.

All the elixirs were lined up and placed on the stone table beside him one by one, learning from King Dan's every move, warming up and adding medicine......

Chen Cheng has refined Pei Yuan Dan countless times, the previous movements were not standardized, but the steps were basically the same, in order to change his bad habits, the speed of alchemy this time was much slower than usual, but after adjustment, he found that the medicinal liquid was more condensed than before.

At the moment before the liquid pill, Chen Cheng took out a round jade box, picked out a drop of spiritual liquid the size of a fingernail and injected it into the Dan furnace, and at the same time played the condensing pill formula, and the spiritual liquid was directly vaporized when it was put into the Dan furnace, forming a spiritual cloud in the Dan furnace, wrapping all the twelve pills that had just been condensed.

The next step is the key moment in the entire alchemy process, especially the control of firepower requires that it be extremely accurate, otherwise it is very easy to have a pill explosion furnace or refining fee, fortunately, Chen Cheng is also experienced in refining Pei Yuan Dan, and after playing the pill harvesting formula, he harvested a full twelve strengthened Pei Yuan Dan without danger, and put it into the jade bottle that was prepared.

Pouring out a pill of Pei Yuan Dan from the jade bottle, Chen Cheng carefully examined it and found that the outer layer of the pill was more delicate than the Pei Yuan Dan refined in the past, and the size was actually a circle, the number of elixirs each time was standard, and where did the big circle come from, it could only be aura.

In order to test the difference between this pill and the past, Chen Cheng swallowed it directly, stood in the middle of the ground, closed his eyes slightly, and carefully experienced the effect of the pill, and after half a minute, a satisfied smile finally flowed on his face.

"Great! This method is effective, not only the level of the elixir has increased by one step, but the increase in the efficacy of the elixir is not a little bit of a star, relying on the aura in the elixir cannot solve a big problem, but it is very important for long-term cultivation, if only it could be added to the spiritual ointment. ”

With a success, Chen Cheng's enthusiasm has been greatly improved, but it is a pity that he has never refined too high-grade pills, and he will be familiar with them for another day, anyway, his parents and family are all cultivating, and the quantity of Pei Yuan Dan is in great demand, so he practiced two furnaces in one go, each time it is twelve pills, and the 100% success rate is a very amazing result, even if it is a pill in the Qi refining period, it is also a very amazing achievement.

If the disciples of Elixir Mountain saw Chen Cheng's alchemy level, it was estimated that they would have the heart to commit suicide, and in one day with King Dan, there would be such a high rate of becoming a pill, even King Dan would not be able to do it when he was young.

Chen Cheng's results came from long-term practice, as well as the assistance of the fire spirit, if he used earth fire, without a few months of exploration, just controlling the firepower was a big problem.

After the alchemy was completed, although his physical strength was still strong, Chen Cheng still took the initiative to stop, and he did not leave the Danfang secret room, and sat in the Danfang on the spot to meditate and recover his vitality.

The next day, King Dan rushed to the Danfang very early, and when he saw Chen Cheng, he couldn't help laughing, "Haha...... Chen Cheng, there are two good news, can you guess it?"

"If that's right, one is to find Liu Zizi's whereabouts, and the other is that you should have tried the medicinal effect of Baicao Dan yourself. Chen Cheng said without thinking.

King Dan stared at Chen Cheng with a strange expression, he didn't know what to do, and he couldn't continue to show off his preparations, "I said, you are too demonic, you can guess this!"

"Is it difficult?" Chen Cheng analyzed, "Since it's a good thing and has something to do with me, there are only these two aspects, otherwise what else can there be!"

"Forget it...... Don't talk about this, you're right, with everyone's efforts, I finally found Liu Zizai's invisible, but he still escaped and failed to capture him on the spot, he was deeply injured, and whether he could resist the disciples of the Great Perfection of Qi Refining is two words, haha...... It's a joy to think about. ”

After saying that, Liu Zizai, King Dan then talked about the process of his test pill last night, after the alchemy was completed yesterday, King Dan took a pill and studied it for a few hours, after feeling correct, in order to verify the efficacy of the drug, he couldn't help but swallow the test pill himself.

When a new category of pills comes out, someone must try the medicine, but this pill fell into the stomach of King Dan, which is a pure waste, Lu Shengming is afraid that he will open his mouth and scold when he sees it, "Try the medicine and find me! How can this kind of rough work be done by King Dan!"

After a night of adjustment, the two of them were energetic, and the alchemy speed was much faster than the previous day, and the three furnaces of pills made a total of 22 pills, which fully achieved the expected goal, but King Dan was not satisfied with the time.

King Dan, like Chen Cheng today, did not leave the secret room of the Dan room, and also meditated on the spot to recover, and there was still a furnace of Centennial Pill materials on the table. (To be continued......)
