Chu Feng was waiting for Yun Changsheng in the Alchemy Hall, and several Heaven-level alchemists also stayed here, very curious about what Yun Changsheng would ask Chu Feng to help do.

And he also came to the Alchemy Hall.

Without making them wait any longer, Yun Changsheng's figure swooped down from the sky, seemingly swooping very quickly, without causing the slightest wind and waves, as if it had come across the void.

"I've kept you waiting."

Yun Changsheng said to Chu Feng.

"Meet the Sect Master."

Several Heavenly Rank Alchemists saluted him.

"Well, I'll take Yang Yun to see the master."

Yun Changsheng said lightly, in the entire Demon Sect, there is only one person who can make him call a master, and that is the only one in the Demon Sect.

That existence that has lived for tens of thousands of years, and its alchemy ability is even higher than that of the Heavenly Rank.

God-level alchemist!

"Sect Master, do you want to see Master Yun Chang Xuan, is there anything important?"

Yun Feng exclaimed, in his mind, Yun Changsheng was an existence that could be compared to Yun Changsheng, and Yun Changsheng's alchemy ability was second to none in the entire Eastern Wilderness.

Especially in the realm of evil sects, there is only one god-level alchemist in the four major sects, and that is Yun Chang Xuan.

"Yes."

Yun Changsheng nodded, stepped into the main hall with a confused Chu Feng, walked towards the depths of the main hall, and ascended to the fifth floor of the main hall.

"What does the sect master want to do when he takes Yang Yun to see Yun Changxuan?"

A Heaven Rank Alchemist looked at their departing backs and was deeply puzzled.

"Will it be ......?"

Yun Feng said tentatively, and the other Heavenly Rank Alchemists quickly understood, and they all showed surprise.

"In that case, it's a big matter for the Demon Sect."

A few people were moved, if it was the same as they imagined, the sect master was going to do something big, enough to make the demon sect's heritage even more terrifying.

"Sect Master, where are you taking me?"

Chu Feng walked deeper and deeper in the palace, and finally couldn't help but ask.

"Don't worry, I'll take you to meet an alchemy master, a god-level alchemist."

Yun Changsheng said with a smile, as soon as Chu Feng heard the god-level alchemist, his eyes immediately lit up, the god-level alchemist, this is an existence that is even rarer than the strongest, and the Demon Sect actually has a god-level alchemist, which surprised him.

"Master, here we are."

Yun Changsheng stood outside the door of the fifth-floor hall and shouted inside.

"Boom~"

The door was pushed open, and an old man who was as thin as wood saluted Yun Changsheng.

"Master, you don't have to salute."

Yun Changsheng helped Yun Changsheng up, Yun Changsheng had a very high status in the Demon Sect, even he didn't put up a fight.

"Who is this?"

Yun Chang's gaze fell on Chu Feng, deeply puzzled.

The sect master had never brought outsiders to see him, let alone a hairy boy who was dozens of years old.

For Yun Changxuan, who had lived for tens of thousands of years, Chu Feng was still a hairy boy in his eyes even if he had cultivated in the Demon Mountain World for more than twenty years.

"He is a nameless apprentice, he has a strong talent for alchemy, and he has researched the method of controlling the process of gathering spirits by himself, I think I can give it a try."

Yun Changsheng said.

Yun Changxuan became serious when he heard the nameless name, looked at Chu Feng's eyes, and then heard that he could actually control the spirit gathering process, and his breathing was instantly short.

"Little baby, can you really control the spirit gathering process?"

Yun Changxuan asked in disbelief.

"High-grade elixirs can do it."

Chu Feng responded.

"Haha, please come in."

Yun Changxuan was overjoyed, showing a kind smile, looking at Chu Feng's eyes softened a lot.

"The sect master brought him here, presumably for that matter."

Yun Changsheng went straight to the topic, over the years, he and Yun Changsheng have put in countless efforts for this matter, but they have never been able to succeed, and they almost gave up a few years ago.

However, after Yun Changsheng saw Chu Feng's method of controlling the spirit gathering process, he once again raised hope, so he brought him over.

"I think there's a good chance of success."

Yun Changsheng said.

"Controlling the spirit gathering process can indeed increase the success rate."

Yun Changxuan also nodded in agreement, but the two of them had a brainless conversation, and Chu Feng was already stunned.

"No, Sect Master, Master, what are you talking about?"

The more Chu Feng listened, the more confused he became.

"Haha, don't worry, young man, show the old man how to control the spirit gathering process, and I'll tell you."

"As long as you can do it, the old man will give you a superb elixir, and swallow it when you break through to the Emperor Realm in the Supreme Realm, and you can break through successfully without any obstacles."

Yun Changxuan smiled, revealing a row of teeth that had lost most of his teeth.

Chu Feng was originally a little unhappy, but under the temptation of the best elixir, he dispelled it in an instant, and this is not an ordinary elixir, it is a top-grade elixir that can help break through to the realm of Emperor Zun, and the temptation for him can be imagined.

The best elixir, let alone swallowing it when the Supreme Realm breaks through to the Emperor Zun Realm, has an excellent effect, and it can easily break through to the Emperor Zun Realm, even if it reaches the core elder level, swallowing this elixir has a good effect.

The best elixir, this is already a kind of elixir that belongs to the highest level of the Eastern Wilderness, only a heaven-level alchemist can refine it, and a heaven-level alchemist can't easily refine it, whether it is the spirit grass required for the best elixir is difficult to find, or the refining process is difficult to control, it is all difficult.

And the best elixir from the hand of Yun Changxuan, the quality of the elixir is even higher, and it is a supreme treasure that countless people want to get.

But any pill that was refined by Yun Changxuan was the best pill in the Eastern Wilderness, even in the decent realm.

"Okay."

Chu Feng nodded, in the face of the huge temptation, he took out a ding alchemy furnace from the Qiankun ring, put it into the spirit grass and began to refine, he was refining a high-level spirit pill, and soon it was time to gather the spirit process, at this time, Yun Changxuan released a powerful divine sense, carefully observing Chu Feng's alchemy process.

Chu Feng didn't hide it, he still controlled the spirit gathering process, and with the refining of a high-level spirit pill, this crystal clear elixir was even amazed by Yun Chang Xuan.

"It's a high-grade best elixir, judging from the quality alone, it has to surpass the old man."

Yun Chang let out an exclamation of exclamation.

"Boy, your ability to control the process of gathering spirits should not be learned from somewhere, the process of gathering spirits is endless, you can predict every change in advance, and then control it to stabilize down, and gather spirits according to your ideas, this ability is simply talented, and it can't be learned."

Yun Chang's eyes were like torches, he was a god-level alchemist, his vision was much higher than Fengyun and the others, just by looking at Chu Feng's refining once, he could see many hidden secrets.

Chu Feng listened to Yun Changxuan's words, fell into deep thought, to be honest, although he could control the spirit gathering process, he never thought about how he did it, at first he thought that other alchemists could also do it, but later he gradually found that it seemed that only he could control it.

Thinking about it, Yun Changxuan's words really made sense, and Chu Feng finally nodded silently, agreeing with what Yun Changxuan said.

"And so it was"

Yun Changxuan suddenly realized.

"At this time, it's time to tell me what the hell is going on."

Chu Feng stood up and asked Sect Master Yun Changsheng, he had already refined a furnace of pills.

"No problem."

Yun Changsheng did not refuse.

"But you must keep this matter secret, even your master can't say it, otherwise, even your master won't be able to protect you, understand?"

Yun Changsheng said word by word, this matter is very important to the Demon Sect, and he does not allow any mistakes.

"Yes."

Chu Feng agreed, and he had a strong curiosity about what Yun Changsheng was talking about.

"Actually, I asked you to help this time, mainly because you can control the process of gathering spirits, the Demon Sect has a psychic level elixir, but it is only a semi-finished product, and it is still one last step away from becoming a real psychic elixir."

"This step is the gathering spirit of the elixir."

Yun Changsheng paused for a moment and continued.

"In the psychic level pill above the best elixir, the refining process is very difficult, even if it reaches the god-level alchemist level, it is difficult to refine it, because the spirit gathering process of the psychic elixir is very unstable, and it will explode if you are not careful, and the Demon Sect only has this semi-finished product of the psychic elixir, and it can't afford to fail."

Yun Changsheng said something.

Over the years, he and Yun Changxuan have looked for various ways, as long as they can strengthen the success rate of alchemy, he will do it at any cost, but they still can't reach a 100% success rate, let alone 100%, even 50%.

"Is this elixir really that important to the Demon Sect?"

Chu Feng asked suspiciously, although the psychic level elixir is very precious, it is one level higher than the best elixir, but Yun Chang is a god-level alchemist, even if he fails many times, he can always refine one, as for the materials required for alchemy, with the foundation of the Demon Sect, it is impossible not to take it out.

"It's very important, and in the entire Heavenly God Continent, there is only this one, if it fails, no other materials can be found to refine it."

Yun Changsheng shook his head, if it wasn't for the help, he wouldn't have gone to Chu Feng, a sect master in the hall went to find a kid to help, if this matter was spread, it was estimated that many people would die of laughter.

"Do you mean that you want me to help you control the spirit gathering process, so that this elixir can successfully gather spirits and become a real psychic elixir?"

Chu Feng didn't ask deeply about the usefulness, and asked other questions.

"Not bad."

Yun Changsheng responded.

"Sect Master, you can't help but think too highly of me, I can't even come out with two top-grade pills, let alone psychic pills, even if it's just to control the process of gathering spirits, but isn't the most difficult thing in alchemy being to gather spirits?"

Chu Feng felt that it was unrealistic to want to complete this matter.

"No, if the old man lends you soul power and lets you control it, it may not be successful."

Yun Changxuan suddenly spoke.

"Soul power?"

Chu Feng was slightly stunned, it was the first time he had heard of such an alchemy method.

Fantastic.
