After knocking Mo Lingfeng unconscious, the Heavenly Wind Medicine Emperor glanced at Kuai Yu with some guilt, and could see that Kuai Yu was frightened a lot, let alone Kuai Yu, even he was no exception, as long as he was a normal man, seeing that kind of disgusting scene, there was no problem if he was not frightened.

"Go back yesterday, can you have a review?" the ice on the face of the Heavenly Wind Medicine Emperor melted, and he looked at Kuai Yu and said in a harmonious voice.

At least this registered disciple is still very normal, talented and highly talented, studying hard, and his achievements in the future are limitless.

"Well, the apprentice looks back on what he learned during the day yesterday and understands something. Kuai Yu nodded.

"Good. The Heavenly Wind Medicine Emperor smiled and said, "Let's go." Glancing at Zhou Erbi and the others, he said in a deep voice, "I'm upset when I see you." ”

The Heavenly Wind Medicine Emperor took Liming, Kuai Yu and others out of the courtyard.

Zhao Ziyun looked at Kuai Yu's back, his eyes were full of gloom, he obviously felt that the master's attitude towards Kuai Yu was not ordinary, not like treating an ordinary registered disciple, he glanced coldly at Zhou Erbi, who was stumbling to stand up, and asked in a deep voice, "What's the matter?"

"It's Kuai Yu's ghost!" Zhou Erbi said with a pale face and desolateness, "Senior Brother Zhao, you can help us." Shizun's impression of us must be extremely bad!" Originally, if he worked harder, he might be accepted as a formal disciple by Shizun, but now, he felt that he was far away from this dream.

"So many people can't even handle a kid in his early twenties, it's really a waste, don't talk about it, go to class first!" Zhao Ziyun said coldly.

Huang Feihong squinted his eyes and looked at Kuai Yu's back, a kid who had just started was so arrogant, if they didn't clean up Kuai Yu, where would their face be?

The one I want to take today is a practical class, and it is also the Tianfeng Medicine Emperor himself refining medicine, of course, refining an ordinary Dapei Yuan Dan, but it is refining in large quantities, and it is open at one time, there are tens of thousands of pills, which scares Kuai Yu a lot.

With his level, the most powerful one is to refine a hundred at the same time, thousands of them have not been tried, and ten thousand of them don't even dare to think about it.

Enter a huge alchemy room, there is a huge Dan furnace in the center of the alchemy room, which is three zhang wide, two zhang high, four feet and ears, and six ventilation holes, which belongs to the top alchemy furnace. And there are more than a dozen sub-level Dan furnaces neatly surrounded by them, which should be exclusively for students.

This is also a big class in the Medicine Emperor Palace only three times a month, and it is also practice, while alchemy, while learning, and at the same time receiving the guidance and improvement of the Heavenly Wind Medicine Emperor.

Kuai Yu is refining a small Pei Yuan Dan, although it is only a small Pei Yuan Dan, but he has not tried a furnace of tens of thousands, he does not dare to have a trace of carelessness, but is very serious and careful, he does not want to be ruined by a small Xiao Pei Yuan Dan in a lifetime.

The serious and rigorous Kuai Yu, in the eyes of other disciples, is instead a pretending gesture to deceive the master and the happy little slippery head, especially those who have been taught by Kuai Yu.

Compared to others, Kuai Yu found that they were extremely calm, and their powerful divine consciousness penetrated the Dan Furnace, Kuai Yu found that this huge Dan Furnace was extremely effective in blocking the Divine Consciousness, with his powerful Divine Sense, let alone the Dan Furnace, even if it was enveloping the entire Medicine Emperor Palace, it was no problem, but it could only enter the Dan Furnace.

At this time, Kuai Yu discovered that each of these Dan furnaces was a medium-grade treasure level.

"The process of alchemy is very complicated, you need a medicine boy to burn the fire on the side, I'll help you find a medicine boy to come over." Liming glanced at Kuai Yu, who was alone, and kindly reminded.

"I usually don't use medicine children in alchemy. ”

After Kuai Yu finished speaking, he noticed that he had said the wrong thing, and at the same time understood why so many people brought one person to class today, and it turned out that they were all medicine boys!

"Just let Ling'er come. Kuai Yu said with a smile.

"Can she?" The medicine boys are all trained, and it takes at least two or three years of experience to know what kind of fire to burn at what stage, but anyway, Kuai Yu is the first time to alchemy, and it is Xiao Pei Yuan Dan, it is nothing if he fails, and if he fails a few times, Kuai Yu will know the importance of the medicine boy, Liming thought for a while, nodded and said, "Then let Weng Shuiling come." ”

Weng Shuiling looked a little excited, they were responsible for lighting the fire and adding firewood, in their opinion, this matter was still quite interesting, stuffing a large pile of firewood under the stove, playing with the fire, the fire was raging.

Dawn Orthodox Church Kuai Yu dealt with the medicine mud, Kuai Yu used not many elixirs for the first time in alchemy, about a thousand copies, and when he turned around, he saw that Weng Shuiling was playing with fire there, and said urgently: "Ling'er, it's not okay to make a fire too early!"

Liming smiled bitterly, Weng Shuiling looks like a serious alchemy!

"It's okay, Senior Brother Li, let them play. Kuai Yu shook his head with a smile.

"Generally, to refine Xiao Pei Yuan Dan, it is almost one hundred and twenty breaths in advance to preheat, it is the most appropriate, it is too early to preheat, the furnace is too hot, and the elixir is put down, and it will be scorched before it is refined. In the process of making alchemy, every detail is very strict, the first alchemy, it doesn't matter if you fail a few times, you know why you failed, so you can accumulate experience for future alchemy. Dawn earnestly admonished, alchemy is not such a simple thing!

Kuai Yu was stunned for a moment and asked, "Does it have to be one hundred and twenty breaths?" He hadn't paid attention to these things before.

"It doesn't have to be 120 breaths, but also according to the heat of the medicine boy's firewood, the heat is strong, the preheating time is shorter, the heat is not prosperous, the preheating time is longer, it is pure experience. And it also depends on the alchemist's true qi attainment, the grasp of the fire system's true qi, etc., all of which you have to experience carefully. Liming said: "The first time you do alchemy, it is normal to fail, but you must learn from the failure." ”

There are thousands of small Pei Yuan Dan refined by Dawn, each furnace is not less than 10,000, and even 100,000 furnaces have been refined, and he has experienced the way, so this one hundred and twenty breaths is not nonsense.

On paper, I finally feel shallow, and I never know that I have to do it!

The process of the Heavenly Wind Medicine Emperor's alchemy technique was much more complicated than the usual alchemy.

"Yes, Senior Brother Li. Kuai Yu nodded seriously.

Liming explained the steps of refining Xiao Pei Yuan Dan and what should be done at each time node to Kuai Yu one by one, and Kuai Yu carefully understood it in his heart, the knowledge in alchemy is really not simple!

Placing the medicinal mud into the furnace, Kuai Yu sat in a position on the east side of the furnace, very close to the fire, and the scorching waves of fire rushed to his face.

"Run the fire-based true qi, use the fire-based true qi to control the flame and control the temperature inside the furnace, at this time, you can also cultivate, improve your fire-based true qi, and be careful not to let the elixir be refined into medicinal mud!" Dawn said to Kuai Yu on the side.

Kuai Yu penetrated the true qi of the fire system out of his body, fused it with the burning flames, and gradually entered a state of concentration, at this moment, Kuai Yu felt that he had become a raging fire burning between heaven and earth.

Feeling the temperature in the furnace, I don't know what happened to the medicinal mud in the furnace?

Whether it is the Heavenly Wind Medicine Emperor or the Dawn, when alchemy, they use the fire-based true qi to control the temperature of the furnace, so that the fire-based true qi penetrates into the furnace, causing the change of the medicinal mud in the furnace, to complete the alchemy, when they use the true qi, they are ignorant of the situation in the furnace, and the experience of alchemy has become a very important thing.

Kuai Yu's thoughts moved, and his divine consciousness extended into the furnace ding, as if he had opened the eyes of heaven, and the changes in the medicinal clay in the furnace ding were all in his eyes.

"It's not good, it's too hot!" Kuai Yu saw that the medicinal mud was a little scorching, and immediately used the fire system true qi to suppress the temperature in the furnace ding.

A trace of fire-based true qi is refining medicinal mud.

At this point, I have to admire Kuai Yu's divine sense, which is far beyond the liberation realm cultivator, otherwise he can't do it at all, even the Heavenly Wind Medicine Emperor is no exception.

Usually he uses his divine sense to alchemize, but this time, he uses fire-based true qi to alchemy, and he carefully feels the difference between the two methods of alchemy.

After some thought, Kuai Yu also had his own thoughts about using the Heavenly Wind Refining Method to refine the pill.

The vast majority of the pharmacists of the Xiuzhen Alliance followed the consistent laws when they were refining pills, lacking their own understanding, and invisibly, Kuai Yu was a level higher than them.

After more than an hour, the dawn who helped the Tianfeng Medicine Emperor deal with the medicinal mud glanced at Kuai Yu's side, and his eyes showed a look of surprise, the medicinal mud that Kuai Yu put into the furnace had not yet been scorched, it was really confusing, you must know that Weng Shuiling, who made a fire there, was a raw hand!
