Mei Xuan was startled at first, and then immediately frowned, and even some displeasure began to flash in his eyes.

This son is really arrogant! I handed over the "Dan Sutra" to him, the holy book of the Dan Dao, in the hope that he could wash away the impetuous aura on his body and really sink his mind into the way of alchemy! He is good, not only does he not learn a lesson, but on the contrary, he has intensified!

What can you learn from this kind of wandering! With such a mentality, I still valued him just now, and I really lost my eyes!

Mei Xuan shook his head, he is usually a down-and-out honest person, and he is already a tendon in doing things, and when it comes to alchemy, it is almost to the extent of following the rules, and he is not far behind those old gentlemen who planted private schools in ancient times.

So when Mei Xuan looked at Su Fei like this, he immediately classified him into the incorrigible category.

Not to mention teaching the way of alchemy, now Mei Xuan can't wait to go up and grab the "Dan Sutra" in Su Fei's hand immediately, because in Mei Xuan's opinion, Su Fei's method of reading books is simply an insult to the "Dan Sutra"!

Out of sight is clear, Mei Xuan forcibly suppressed the anger in his heart, and he couldn't drive Su Fei away, so he had to divert his attention and start to deal with the documents piled up on the table, but Su Fei's "frivolous" appearance always lingered in his mind, making it difficult for him to calm down.

The more this was the case, the more irritable Mei Xuan became, and he even planned to leave Su Fei here alone to go out for a walk.

"Mei Xuan, how did you teach Su Fei?"

Mei Qianli's laughter came from outside the door, and then the door was pushed open, and Mei Qianli and the Seventh Master paced in at once, talking and laughing.

As soon as she entered the door, Mei Qianli saw Su Fei who was concentrating on the sofa to "study" the "Dan Sutra", looking at the seriousness in Su Fei's eyes, Mei Qianli couldn't help but nod lightly.

Looking at his father's appearance, Mei Xuan felt that he almost didn't catch his breath, but he didn't have a seizure on the spot, so it took a little bit to smooth his breath.

"Daddy......" Mei Xuan got up and stepped forward, opening her mouth to say something, but she still didn't hold back half a word after holding it for a long time.

Mei Qianli looked at Mei Xuan's appearance and laughed: "What, Su Fei's talent is too high to scare you?

Hearing Mei Qianli's words, Mei Xuan suddenly felt that his heart was stuck in one breath, and he couldn't hold it back.

But he was afraid of everyone's face, and still said euphemistically: "I feel that Su Fei may not be the material for alchemy, father, I think ...... Forget it. ”

"Forget it, I think I'm looking at it very well. Su Fei had just absorbed the relevant memories of the previous page, and it was just the gap when his head was empty, and he just happened to hear Mei Xuan's words.

Su Fei reluctantly put down the "Dan Jing" in his hand, and said with a smile: "I think this "Dan Jing" is really interesting, many things said in it can be mutually corroborated with what I have learned, Brother Mei Xuan, where do you see that I have no talent for alchemy?"

"You ......" Mei Xuan didn't want to tear his face, but as soon as Su Fei's words came out, his anger was stirred up again. Mei Xuan glanced at the "Dan Sutra" that Su Fei put aside, only to find that Su Fei had actually read more than a dozen pages, which made him suddenly angry!

Originally, I was giving you face, but you are still pretending to be here for me! Well, the face was given by others, and you also lost it yourself, so don't blame me for telling the truth afterwards!

The "Dan Jing" was a holy relic in Mei Xuan's heart, and now that he was "desecrated" by Su Fei in front of him, he couldn't bear it anymore, and roared with suppressed anger: "Su Fei, if you are talented, can you read the Dan Jing so quickly!

"Dan Dao is as vast as a sea of smoke, we can't exhaust the Dan Jing in case we diligently, and even every word and sentence in it is just the life's work of those Dan Dao predecessors in the past, that's how you read me the book? This is your talent! I think you have a talent to brag!"

Since he said it, Mei Xuan was not hiding, he turned his head to look directly at Mei Qianli, pointed to the Dan "Dan Jing" in Su Fei's hand and sneered: "Father, look at it yourself, it's only been just over an hour, how many pages has he read!

Mei Xuan pointed at Sophie Fei and said, "I'll ask you, where have you learned what you have "learned"!

"What I Mei Xuan usually hate the most is people who are sensationalizing and floating on the surface, people like you are not suitable for learning alchemy, and my son Zhenyi doesn't need a master like you!"

Mei Xuan usually has a mild temper and rarely gets angry, but now this honest man is really angry when he is angry, and the roaring voice immediately attracted the rest of the Mei family over, Wang Man hurriedly squeezed out of the crowd, stretched out his hand behind him and gently pulled the corner of Mei Xuan's clothes, signaling him not to say any more.

Su Fei didn't think that Mei Xuan was so angry, and he had just heard it, the reason why Mei Xuan was angry with himself was just because he was reading too fast? Can I blame me! This is because he is borrowing the "Dan Jing" to fuse memories, and of course fusing memories is fast!

Su Fei couldn't laugh or cry, but he didn't know how to explain it.

Although the Seventh Master doesn't understand Dan Dao, there are still many similarities between the Medical Dao and Dan Dao. He understood Mei Xuan, so he simply kept silent beside him.

Mei Qianli understood Mei Xuan's temperament, and naturally knew why Mei Xuan was suddenly angry. To be honest, as long as he is an alchemist, he will inevitably have fire in his heart when he sees a layman like Su Fei wantonly "desecrating" the Dan Dao Holy Book in his heart.

However, Mei Qianli is more sophisticated than Mei Xuan, and he laughed and said, "Su Fei, look at what you have made me angry." The knowledge in this "Dan Jing" is obscure, you should still calm down and think more, I know that you are talented, but reading fast does not mean that you can really understand. ”

Su Fei couldn't laugh or cry: "But I really understand, do you want me to pretend not to understand? That's a waste of time." ”

"Look at it, look at it!" Mei Xuan's anger that had just subsided when he heard this came up again: "Then let me ask you, you say you understand, then I will test you, if you can't answer, don't study alchemy in front of my Mei family in the future, do you dare to respond!"

"Take the test!" Su Fei's eyes lit up: "But let me say it first, if I answer, then what do I say?"

"You can't answer it!"

"Not necessarily. ”

The two of them faced Mai Mang, which was completely on the bar.

Mei Xuan looked at Su Fei's appearance as the old god was there, and he was angry, and suddenly burst out with a sentence: "If you can answer, then I will bow down, and wherever you Su Fei goes in the future, I Mei Xuan will retreat, how about it!"

"That's not good, Brother Mei Xuan, you are serious. Su Fei shook his head, he thought about it, and said with a smile: "That's it, if I answer, you let me take this set of "Dan Sutra" home and study it for a month." How?"

"Okay, that's it!"

The surrounding Meng family members were stunned one by one, you must know that Mei Xuan is usually kind to everyone, and it is the first time they have seen Mei Xuan like today, and they all have a somewhat angry appearance.

Mei Qianli and the Seventh Master glanced at each other, but no one spoke.

"Dad, Seventh Master. I'll ask three questions, and I won't bully Su Fei, all the questions are the contents of these dozen pages!" Mei Xuan ignored the hints that Wang Man had been giving him behind him, and stretched out his first finger: "First, under what circumstances can the active ingredients in the red blue copper be extracted? This is the content of the third page of the "Dan Sutra", you should have read it all, now answer me. ”

"You're underestimating me. Su Fei couldn't help but smile: "Red blue copper, when used, it needs to be steamed and boiled in water for more than half an hour, and its surface is completely transformed into blue copper oxide of dodecahydrate, and heated to about 1400 °C-1580 °C with high temperature fire isolation, the outer layer of the magazine will be effectively separated from the blue copper oxide of dodecahydrate." After scraping off all the outer layer of copper oxide dodecahydrate, continue to steam for one hour, and repeat the cycle, all the active ingredients in the red blue copper can be completely extracted. I'm right. ”

In fact, when Su Fei was just halfway through speaking, Mei Qianli had already determined that Su Fei really knew the refining method of this red blue copper, but these were all things clearly recorded in the books, which could only show that Su Fei was indeed unforgettable, but it couldn't explain much else.

Mei Xuan was stunned for a moment, he didn't expect Su Fei to really be able to say this, but just like Mei Qianli, he only attributed it to Su Fei's unforgettable, although he was surprised, he didn't take it too seriously.

"Listen up, second question. Mei Xuan raised a second finger again: "If the purple blue grass and the galaxy sand are put together, what kind of reaction will they cause?"

Mei Qianli smiled slightly, this tested Su Fei's comprehension ability, although there was detailed information about the two things in his book, the purple blue grass and the galaxy sand, but it rarely touched on the changes of the two in alchemy. Because these two are simply too common medicinal materials, even an alchemist should know about them, so they are not discussed in the Dan Sutra.

That being said, as long as Su Fei really understands the traits of the two, then it is impossible to infer from it the reaction that the two will cause after they meet, Mei Xuan's question is a test of Su Fei's comprehension ability, if he is a fool, he will definitely not be able to answer!

Mei Xuan looked at Su Fei's thinking appearance, and there was already a faint happiness in his heart. Let you be so grandiose! Look at you in the future, you will still have the face to refine the word Dan in front of my Mei family!

Who knew that before Mei Xuan could feel proud in his heart, Su Fei suddenly said, "Your question is not difficult." ”

"Purple blue grass belongs to water, and galaxy sand belongs to fire, and when the two come together, it is nothing more than that the medicinal properties of purple blue grass will be neutralized by the galaxy sand, but under normal circumstances, there are some impurities of the wood genus in the galaxy sand, which will play a role in the presence of the juice of the purple blue grass, if the quality of the galaxy sand used is not high and there are too many impurities, it will suppress the fire attribute of the galaxy sand itself, turn fire into wood, and the two will combine together to become a similar associated state. ”

"If I'm not mistaken, this is probably also an improved way to cultivate purple and blue grass, using the magazine of Xinghe Sand to improve the soil quality, so that it can be planted artificially in some extreme environments. ”

“…………”

There was silence for a moment on the scene, and a pin drop could be heard.

The Seventh Master didn't understand these things at all, but from the perspective of his understanding of the attributes of the medical Dao, Su Fei seemed to be right.

But Mei Qianli is not like this, he is sure that what Su Fei said is not wrong at all!

Not only that, what Su Fei said is also a cultivation method of purple blue grass, because purple blue grass likes water and is not easy to cultivate in the dry soil in the northwest, so some people use Xinghe sand with more impurities as raw materials to change the soil quality, so that the purple blue grass can adapt to it and continue to grow in this artificial environment!

This method is not a secret, the Mei family basically knows it, so when Su Fei said it, they were a little impressed with Su Fei one by one, because this is not just rote memorization or memorization can be explained, this is really after fully understanding the meaning of these words!

Mei Xuan began to sit on pins and needles now, he was originally ten percent sure that Su Fei couldn't answer this question, but now that he was doing this, he suddenly found that he seemed to have really misseen Su Fei!

Su Fei is not a casual observer, he really reads books so fast!

For a while, Mei Xuan was sitting on pins and needles, and the third question was not asked for a long time.

Because no matter whether you ask it or not, this third question has no meaning, Su Fei really understands, and can draw inferences from one another, and guess that this is an improved cultivation method of purple blue grass!

I was really mistaken!
