After listening to the class, Su Lun had a basic understanding of alchemy, which is the process of volatilizing the medicinal properties of herbs to make them into pills by controlling Xuan Qi.

Among them, there are two points that are the most important, one is the degree of compatibility with the herbs, if you understand the medicinal properties of the herbs very well, and can feel its changes at all times during the refining process, then you can refine the pills extremely efficiently.

And the second point is the control of Xuan Qi, if you want to refine the pill, you must first ignite the Xuan Qi and turn it into a Xuan Huo, so that you can get a higher temperature, so as to control the Xuan Qi to refine the pill, ordinary fire is not able to refine the pill, whether it is the change of temperature, or to maintain the control of the temperature, the Xuan Huo is the best choice, this is the experience of countless years of alchemists.

Therefore, the first step to becoming a Dan Xiu is to be able to release Xuanhuo.

"Brother Su, are you going back?"

Su Lun was about to leave, but was stopped by someone.

He turned his head to look, and a young man was looking at him, this young man Su Lun knew that his name was Huo Feng, and he was also one of the few people who had just entered Danfeng and listened to the lecture with him.

At this moment, he shouted to Su Lun, and several people around him also looked at him at the same time, as if waiting for his answer.

Su Lun nodded, and then listened to Huo Feng say: "We are the same batch of Dan cultivators who came in this month, and there are only a few of us in this class, so I want everyone to get to know each other, and if there are problems with cultivation, it is better to communicate." ”

Su Lun thought about it and nodded, he didn't know anyone here, and interacting with some people might also help him alchemy.

After several people agreed, they decided to open a small stove together, that is, to eat some medicinal food together.

Compared with other cultivators, Dan Xiu does not pursue combat ability, but the realm must be able to keep up with the progress of Dan Dao, and usually everyone rarely puts their minds on cultivation, medicinal diet has a lot of benefits for improving the realm, and there are no side effects, so Dan Xiu's demand for medicinal diet is still very large.

Several of them were newcomers, and they were not rich, but Huo Feng was obviously a big family, and said nonchalantly: "I invited this meal." ”

During the chat, a few people knew that Huo Feng was born in a big family, and he was a family of cultivators, but there were very few Dan cultivators in the family, and recently the family wanted to expand the pill business, and the heir needed to have a certain amount of Dan Dao cultivation, so they sent Huo Feng here, but looking at his appearance, he obviously didn't want to come, according to him, he came here to make friends.

However, Su Lun could also feel it when he talked with him, although this person was a rich second generation, but he did not have the arrogance of the rich second generation, but was very funny, but somewhat similar to Lu Lin.

While a few people were talking, Su Lun realized that in fact, there is a customary custom in Danfeng, that is, a group of people who come in every month will generally form a small group, so that it is easier to make progress with mutual help. Most of Dan Xiu are very busy, and few people are really willing to take the time to teach their younger brothers and sisters, so this small group is particularly important.

In the morning lecture, everyone will have more or less questions, but after communicating with each other, most of the doubts have gone, and after this time, the relationship between several people has become closer.

After eating, a few people came to the alchemy, where there is a special induction room for Dan Xiu, which can simulate the process of Xuanhuo generation, generally speaking, new Dan Xiu must come here in order to learn the generation and use of Xuanhuo more easily.

On the other side is the alchemy room, at this moment, many people walked in and out of those alchemy rooms, and saw Su Lun and a few of them enter the induction room, and someone said to the person next to him: "You said that this month's newcomer, how long will it take to learn to stimulate and use Xuanhuo stably?"

The young man next to him sneered and said, "I think it will take at least a week, I haven't heard that this month is too talented." ”

"I think too, not everyone is a genius like Su Qianqian, hey...... People are more popular than people. ”

"Su Qianqian, that's it, don't you still have to learn it for more than half a year, compared with Senior Brother Zhou Poyang, it's still a lot worse. Speaking of Zhou Poyang, the young man's eyes were obviously hot, as if he admired him very much.

"But Senior Brother Zhou Poyang's foundation is much better, he is a cultivator of the Fusion Realm. By the way, how long did it take you to get there?"

The young man wanted to refute again, but when he heard this, his face suddenly turned red, and he hesitated: "Uh...... Let's ...... a few days."

"A few days, a few days?"

"Forgot!"

......

Naturally, a few people outside had no way of knowing, so each person chose a small room, and then said goodbye to each other and entered.

Su Lun walked into the room, and in front of him was a sculpture-like model, life-size, lifelike.

He took a closer look and found a red button on the sculpture's arm.

Pressing it, he suddenly felt that there were Xuan Qi fluctuations in the sculpture's body, and those Xuan Qi gradually surged to the sculpture's outstretched right arm, and then gathered in the palm of his hand.

As the amount of Xuan Qi gradually increased, there was movement within the Xuan Qi Mass, and the Dao Xuan Qi squeezed and collided with each other, but it was confined to the boundary of the spherical Xuan Qi mass of fixed size.

As the Xuan Qi became more and more, the friction became more and more intense, and Su Lun could feel the temperature inside it getting higher and higher, until there was a certain critical point, and there was a "boom". A flame appeared from his hand, and the model continued to infuse it with Xuan Qi, and the flame kept burning, and after a while, the sculpture model stopped infusing Xuan Qi, and the flame gradually went out.

"It's as simple as that?"

Su Lun looked at the flames that gradually disappeared in the model's hand, and was a little stunned for a while, he thought that it was very difficult to stimulate the Xuanhuo, and the elder also said not to be impatient, observe carefully for a few days, but he didn't expect it to look not too difficult.

This principle is actually very easy to understand, and he who was educated in his previous life naturally knew that generally speaking, the greater the pressure of the gas, the lower the ignition point. Although he felt that Xuan Qi was not a gas in the conventional sense, he could see that many properties were still similar to gases, and after high-density compression, Xuan Qi was already easy to burn, and then continued to collide strongly, generating more and more heat, and being gathered in a small boundary, so that it would spontaneously combust to a certain extent.

He didn't know that although this principle seemed simple, it was difficult for people in this world to understand.

Of course, the most important thing is that Su Lun can clearly perceive the changes in those Xuan Qi by relying on his own divine thoughts beyond ordinary people, but many people do not have such an amazing perception as him, and they can't feel the changes in the palm of the model, so it takes a long time to try before they can slowly figure out the truth.

Su Lun followed the movements of the model, gathering Xuan Qi in the palm of his hand, but found that it was not easy.

This Xuan Qi is a formless and insubstantial thing, and it is not easy to feel its shape, and it is even more difficult to gather it in the palm of your hand, and to use it to create a small spherical shell to limit the volume of Xuan Qi.

Su Lun had been trying to gather the Xuan Qi into a ball and hold it, he had tried dozens of times in a row before he gradually found the trick, and after successfully activating the Xuan Huo once, remembering this feeling, it would be much easier to stimulate it again in the future, and by the evening, he had been able to successfully activate the Xuan Huo seven times out of ten.

At this time, he realized that this first step seemed simple to him, because he knew the principle, had a strong perception, and had the experience of cultivating the Shattered Sky Divine Fist to gather Xuan Qi, so that he could successfully stimulate the Xuan Huo relatively smoothly, and ordinary people did not have these prerequisites, so it was naturally very difficult to perceive these things.

"Goo-Goo......

Su Lun put himself into practice again and again, and there was special lighting in the room, so he couldn't sense the passage of time through the changes outside, until he felt hungry, he came out of the inside, ready to fill his stomach first.

When he opened the door, he found that there were already a few people outside the door, they were discussing something, and when he saw Su Lun coming out of the door, a female cultivator smiled at him and said, "We were still discussing it just now, saying that you might come out later." ”

Suren asked, "Why is that?"

Huo Feng smiled and said, "Although the stimulation of Xuanhuo is very boring and difficult, we feel that you are the most calm, and you should try more time, no, we have been standing outside for a long time." ”

Then he asked, "How? Can you feel how the hell that model came up with the Flame?"

Without waiting for Su Lun to answer, he sighed again: "Needless to say, I know if there is none, just say that it is a spherical shell made of Xuan Qi, and it took me a long time to feel that it actually plays the role of isolation." ”

"Ah, the effect of isolation, I thought it was for the sake of good looks......"

A somewhat chubby man was stunned and muttered.

"Haha......" Everyone laughed, but they didn't laugh at him, but instead talked to each other about their discoveries.

"Eh, Brother Su hasn't said anything about his progress yet. ”

"Oh yes, I forgot about it. Then they looked at Suren and waited for his answer.

"Ahem...... I said that I was able to produce a Xuanhuo, do you believe it? Su Lun said slowly.

"Phew...... Is there anyone more shameless than me?" Huo Feng pursed his lips and said, "You must know that Su Qianqian has spent most of the day, she is a genius that has been rare for many years, can you be better than her talent?" If you can stimulate it, I will invite you to take a month's medicinal diet!"

Su Lun knew about Su Qianqian's matter for the first time, and asked, "How long did it take for Qianqian?"

"Hey, brother, you can't be so shameless. Not only Huo Feng, but several other men also pretended to look at Su Lun with disgust and said, "Su Qianqian is the goddess of our Danfeng, and she is still shallow...... If you call her like that outside, make sure a group of people come and teach you how to behave. ”

"Ah, goddess, how long has it been, how can you become a goddess......" Su Lun was stunned, a little incredulous.

"At first glance, you just don't pay attention to all kinds of gossip news about our Danfeng, Su Qianqian has been growing in popularity throughout Danfeng since she came, and now she has become a recognized goddess, I don't know how many Dan Xiu wants to make friends with her, but although she is both good-looking and talented, her personality is really cold, and she rarely talks to people, hey......"

Huo Feng shook his head as if he was a little pity, and then came back to his senses and said, "Don't talk about this, we rookies who don't have a beginner, let's think about what to eat at night......"

......

At night, although Su Lun was also assigned a place to live in Danfeng, because there were still some herbs to be brought over from the original residence, and he also wanted to talk to Lu Lin and them, so he went back to sleep.

The next day.

"What, do you want to do alchemy?" Lu Lin's eyes widened, as if he knew Su Lun for the first time, and asked, "By the way, I didn't see that you kid still has the talent to become a Dan Xiu." ”

Su Lun said: "I have to do it as a last resort, this does not delay my cultivation, but you don't want to tell others about this, and if there is anything in the club that I need to do, I may not have the right time, so I need your help." ”

Lu Lin first instinctively shook his head, but suddenly nodded frantically, and then smiled, looked at Su Lun directly, his eyes seemed to glow green, and said slowly: "Then I will use the pill in the future, is it okay to find you directly." ”

"Yes, the normal price is as much as you want. ”

"Hey...... Don't bring this, let's have a relationship, Lao Su, you can't treat me like this, I'm very lonely in this place, just a friend of yours...... Besides, I still have to help you", Lu Lin said in a pitiful tone, but his eyes were rolling, thinking that the pill would fall in the future.

Su Lun shook his head and hurriedly took a step back, but he also knew that Lu Lin's kid seemed to be a little unreliable, but he was actually very righteous, and he didn't have to worry about the affairs of the sect with him, so he said: "Okay, when I can refine the pill that is useful to you, I will help you refine the pill if you provide the materials." ”

Lu Lin's eyes lit up, and he nodded while humming: "Okay, don't blame me when your kid is tired and prostration." ”
