After the old man said that, he continued to concentrate on refining the elixir.

"It's okay, you can do it yourself, don't worry about me. Seeing that this person was polite and got busy, Zhou Yang was a little dumbfounded, but he didn't care, he sat down on the futon not far from the Dan furnace, and quietly watched the old man's alchemy.

He had already used his divine sense to probe the old man's cultivation, and he was even more surprised in his heart. Because the other party's spiritual power fluctuates from time to time, it is very similar to when I first met Fan Yuan, but there are also some differences.

At that time, although Fan Yuan's aura was faint, he couldn't see his realm at all. Although the spiritual power of the old man in front of him came and went, and judging from its fluctuations, it seemed to be similar to that of a cultivator in the early stage of Kaiyuan.

However, with Fan Yuan's precedent, coupled with the fact that this person's divine sense is extraordinary, it is still possible that the Tian Yuan cultivator has restrained his breath.

The old man's concentration on alchemy didn't seem to pay attention to Zhou Yang.

However, Zhou Yang did not dare to relax, and was still on guard.

After half an hour of this, the old man's eyes suddenly widened, and the essence of light burst out, and quickly closed several fire outlets under the Ding furnace, leaving only a small half.

After a few moments, he let out a sigh of relief, wiped the beads of sweat from his forehead, and relaxed.

Zhou Yang saw it clearly, the white-bearded old man's alchemy technique was very skillful, and the entire refining process was no different from that of the cultivator alchemist, the only difference was that he did not use spiritual power or yuan power.

But the alchemy he uses is actually earth fire!

In the secular world, there is no shortage of people who use fire to refine pills, but those who can lead the fire into the room for alchemy have never heard of it in the mortal world, and it is estimated that the old man in this hall is the first person.

The white-bearded old man rested for a while, then stood up and saluted Zhou Yang, and then said: "The old man was not well entertained, so he made Daoyou wait for a long time. ”

"Daoyou is polite. Zhou Yang also got up and returned the salute.

From the moment he entered the door, the old man was polite and polite, and there was nothing out of the ordinary, and there was no malice in his eyes, so Zhou Yang breathed a sigh of relief.

"Fellow Daoists sit down, and you can taste the fragrant tea of Jin Chengguo later. The old man sat down, turned around and walked to a large table, and returned after a few breaths, holding two bamboo teacups in his hands.

"Fellow Daoists, please. ”

"Thank you!" Zhou Yang took the teacup, glanced at it, and did not drink it.

"This tea is not as good as Yunxia Mountain Spirit Tea, it is just an ordinary product, but it is mellow and delicious, and it has a long aftertaste, and it is also the best in the mortal world. The old man sat down and took a sip of his own drink.

"This old man is really interesting, the uninvited guest is here, and he is indeed leisurely, completely unguarded, is it the strength of detachment or is it the nature of this?" Zhou Yang couldn't help muttering in his heart when he saw this.

"Daoist friends have a great name, I don't know what to teach here?" After taking a sip of tea, the white-bearded old man asked.

"Zhou passed by Jin Chengguo, and happened to hear that there was an immortal master in the palace, but as far as I know, Jin Cheng is a subordinate country of Dingbei Zhou Tianzong, and he never allows cultivators outside the sect to interfere in state affairs, let alone enter the palace, so he was very curious after hearing about it, and he came to visit today. Zhou Yang smiled.

"It turned out to be Zhou Daoyou, and the old man was polite. My Taoist friend is not very old, but his cultivation is unfathomable, and he is really a genius. Dare to ask Where is Youxian Township?" the white-bearded old man put down his teacup and hugged his fist.

He didn't solve Zhou Yang's doubts, but asked about his origin.

"Daoyou praised it falsely. In the lower guest residence in Dingbei City. ”

"Oh. Forgive the old man for taking the liberty of being presumptuous, did Zhou Daoyou join Zhou Tianzong or the peripheral forces?"

"Daoyou is really discerning and admires it. Yes, Zhou is now working for Tianxingmen. "Since this person dares to stop at Jin Chengguo's palace, it is likely that he has some relationship with Zhou Tianzong, so Zhou Yang will tell the truth.

"The old man is disrespectful. ”

"Daoyou is polite. In addition to the above doubts, there is still one thing that is unclear, and I hope to give you a lesson or two. Seeing that the old man still didn't answer, Zhou Yang asked directly.

"Hehe, please. The old man stroked his white beard and said.

"Daoist friends are extraordinary, and they are proficient in Dan Dao, if they are placed in any sect in Dingbei City, they are also highly valued people. But why did the Taoist friends abandon the city of the cultivation realm and go to a small secular country? In this way, wouldn't it be an insult to the Taoist friends?"

"Hehe, what Zhou Daoyou asked was puzzled, and the old man could answer it together. To be honest, if it weren't for the fact that Daoyou and Zhou Tianzong had some origins, the old decay would not have told each other. ”

The white-bearded old man smiled, as if he had known that Zhou Yang would have such a question, so he didn't solve his doubts first, and pointed out the reason, it was because you had some relationship with Zhou Tianzong, so you told the truth.

"Thank you. Zhou Yang was even more puzzled in his heart, could it be that this person also had something to do with Zhou Tianzong?

"As Daoyou said, Zhou Tianzong does not allow outsiders to enter Jin Chengguo, let alone set foot in the palace, but speaking of the old man, he can be regarded as half a disciple of Zhou Tianzong. ”

"Half a disciple of Zhou Tianzong?" Zhou Yang was even more puzzled.

"That's right, the old man's surname is Ye Chongshan, and he was originally the deacon of Zhou Tianzong's Dan Instrument Room. "The white-bearded old man spoke amazingly!

"Deacon Zhou Tianzong!" Zhou Yang's color changed, and he almost stood up in shock, and even had the urge to flee.

Although he had all kinds of speculations, he never expected that this person would have such a big background.

But all the deacons of the great sects are at least the early stage of Tianyuan cultivation, and there is no shortage of masters in the middle and late stages.

From this point of view, the person in front of him is also an old monster who has lived for one or two hundred years, and he must have hidden his cultivation.

However, if the old man was really a master of Tianyuan, with the distance between the two, Zhou Yang would be too late to run, so he could only suppress his fear and barely sit still.

"Alas, the so-called deacon is just a passing cloud!" Ye Chongshan sighed, full of loneliness.

"What do you say about the seniors?" Since Ye Chongshan was once a deacon of Zhou Tianzong, it was obviously inappropriate to have a relationship with his peers, so Zhou Yang immediately changed his words, and his attitude became much more modest.

"I don't know how much you know about Danshu?" Ye Chongshan changed the topic and asked rhetorically.

"Oh, I don't know. "If it weren't for Zhou Yangji's change, he really wouldn't have been able to keep up with the rhythm of the old man's speech.

Of course, he would never reveal that he also knew the art of alchemy.

"Not to mention low-grade pills, the higher the grade above the middle and high-level, the lower the pill rate. Some high-grade pills have an outrageously low success rate.

Many factors will affect the success rate of high-grade elixirs, such as the quality of the materials, the temperature of the flame, the proficiency of the fire mastery, the strength and cultivation of the alchemist's divine sense, etc., the slightest deviation will fall short.

Moreover, although some pills have been formed, if there are slight differences in the proportion of materials, the efficacy of the pills will be far from the same. The old man said slowly.

Zhou Yang nodded, these are all words of experience, and he also has a deep understanding. But the last point made him feel a little aftertaste.

If there is a deviation in the ratio of materials, it can also become a pill, but the medicinal effect will be different, and this sentence suddenly reminded him of the fire spirit pill he had refined.

Originally, he wanted to refine the Yellow Spirit Pill, but because he was short of the grass in the rock, he had to replace it with the fire rock grass under the hot spring peak, and by chance, he actually refined the Fire Spirit Pill. Its medicinal efficacy is even more different, and the quality is also higher than that of Huang Lingdan.

"It is precisely because the refining power of high-grade pills is too low, although the formed pills know that the efficacy is slightly different, but because the difference is not big in most cases, they are not abandoned. But what kind of difference there is, and how much it is different, can only be known after the alchemist has tried it. ”

"The alchemist personally tried the medicine?" Zhou Yang was a little stunned.

The alchemist has a lofty status in the sect, and he actually let them do this kind of thing, isn't this overkill, and extremely dangerous, if there is a mistake, but there will be an accident.

Those sects, can they be willing to give up the alchemists who have been cultivated with great difficulty?

"Yes, although it is okay for others to test the medicine, ordinary people can't try the medicinal properties, and the more high-grade the pill, the more high-level alchemists are needed to try it. The old man continued.

Hearing this, Zhou Yang had a faint guess.

"It's rare for the unexpected, but it's still there. Old and unfortunate, there was an accident when testing the drug. That pill was originally used to heal wounds, but after the old man took it, the meridians were broken, and the cultivation was completely wasted, but fortunately, the elders in the sect took action, and the old man saved his life.

Later, he was treated by a wise physician and took a large number of rare pills, so that the old meridians were restored, and he barely retained his cultivation in the early days of Kaiyuan.

It's just that this kind of cultivation comes and goes, and it's very unstable, which is equivalent to being half wasted. However, fortunately, the damage to the old and decrepit divine consciousness was not too great, and it was still equivalent to the level of the peak of the spiritual platform. ”

"Ah! I was wrong again, this peer turned out to be really in the early days of Kaiyuan!" Zhou Yang secretly smiled bitterly, this was frightened by Fan Yuan.

At the same time, he was also scared in his heart. At the beginning, after refining the Fire Spirit Pill by accident, he swallowed it without hesitation, if an accident happened like Ye Chongshan, and he was in a Jedi, the result could be imagined.

"Cultivation is almost half-wasted, and no matter how refined the alchemy skills are, it is in vain. Refining the lowest-grade pills is a bit reluctant, so staying in the sect is also a waste, and he has no face to serve as a deacon in the pill room.

The old man was disheartened, so he stayed away from Dingbei and returned to his hometown of Jin Chengguo Chengtian County to live in seclusion. Later, His Majesty the Emperor learned the whereabouts of Lao Yu from the disciples of Zhou Tianzong who were inspecting, so he sent someone to ask Lao Yu to come out of the mountain and refine the pill for the royal family.

However, the old man has no intention of Dan Dao, and he has not much life, so he is only waiting to bury his hometown, so he naturally refuses His Majesty's good intentions. His Majesty saw that the dispatch was fruitless, so he went to Chengtian County to invite him.

Originally, the old man still did not agree, but His Majesty said that the earth fire was found in the palace, and the quality was not low.

But the old decay is still an immortal master, but he is only slightly stronger than mortals. Therefore, the old decay has been explained, and it must not be commensurate with the immortal master. Who would have thought that it would later be rumored to become the so-called Asian Immortal Master, which really made the old man extremely helpless. ”

"So that's the case, then this hall ......" Zhou Yang suddenly asked again.
