Facing the angry Tang Feng, Xiao Yu said calmly, and said indifferently: "Elder Tang, the juniors are not messing around, if you don't believe it, you can test me." ”

Tang Feng saw Xiao Yu's appearance, his chest rose and fell, and he was obviously angry: "I'll only give you this chance, ask you ten questions, if there is a mistake, you can get out!"

"Good. Xiao Yu's face was serious, and he nodded in agreement.

In his heart, he sighed, this Elder Tang is really more serious.

Zhao Chun on the side had a gloating expression on his face, thinking, let you pretend, pretend to be too much, and pretend to be a fool, right?

Tang Feng took the three basic textbooks and said coldly: "It's not difficult for me to test the content of your three books." ”

Xiao Yu's face was calm, and he looked like he was in his chest.

Tang Feng saw that Xiao Yu was still calm and calm, and wondered in his heart, could it be that this little guy really had the ability to never forget?

He shook his head, thinking that it was unlikely, such a genius, he had never seen a few in the entire Qianfeng Kingdom, this kid was just humble and studious.

Tang Feng put aside the distracting thoughts in his heart and began to ask Xiao Yu questions about "Basic Material Matching", "Basic Furnace Method" and "Basic Pill Control Heart Formula".

The focus of his questions was mainly on the first two books, because "Basic Pill Control Tips" is too difficult and profound for novices.

Although he was not satisfied with Xiao Yu's attitude, Tang Feng did not want to deliberately make things difficult for Xiao Yu.

In fact, when Elder Tang explained these three basic books, the purpose was to let Xiao Yu familiarize himself with and understand them first.

After all, although Xiao Yu has a good talent, if he does not systematically learn the knowledge system of alchemy, it will be difficult to go long in the future.

Tang Feng didn't want this talent to be unknown to everyone.

But it was only less than half a day's work, Xiao Yu actually boasted that he had basically learned it, and of course Elder Tang didn't believe it.

The geniuses he has seen are like carps crossing the river, and those who are pretentious are mostly the superficial ones who comprehend things.

Thinking of this, he was angry with Xiao Yu.

Clearing his throat, Tang Feng began to ask, "The first question, what is alchemy?"

This question is also one of the easiest.

"The so-called alchemy is to extract the essence of all things in heaven and earth and condense it into a common form of elixir, or other forms. Its characteristic is a "refining", the alchemy of the world, almost indispensable to the auxiliary ...... of Danhuo"

Xiao Yu talked eloquently, not only answering Tang Feng's question perfectly, but also putting forward some of his own opinions.

The first question was very simple, Xiao Yu could answer it, and Elder Tang and Zhao Chun were not surprised.

Immediately following the second question, Elder Tang Feng increased the difficulty.

"Tell us a little about the selection and matching of alchemy materials. ”

Elder Tang looked at him quietly.

"Between heaven and earth, everything has its own attributes, and materials with different attributes contain different essences of heaven and earth. Even some spiritual objects contain mixed attributes, as well as some unique characteristics, this fusion is extremely complex, but there are roughly certain rules to follow......"

Xiao Yu replied fluently, and a huge amount of information appeared in his mind.

"In alchemy, what ...... need to be paid attention to in the process of fire control?"

The difficulty of Elder Tang's question was further increased.

For a novice, asking him questions about "fire control" was almost a bit harsh, especially when Xiao Yu hadn't mastered any alchemy techniques.

This is the most esoteric part of these three books.

"Hehe, before the martial artist, the alchemist was not able to cultivate his own soul fire, so he needed to control the flame of the outside world, that is, the furnace fire. Xiao Yu paused and continued to answer, "The fire in the furnace is greatly disturbed by factors such as temperature and air humidity, and the selection of materials is also extremely harsh. For example, the flame produced by the higher black cloud carbon is more stable, but the temperature is not high. There are also some fire-attribute crystals that can produce flames that are easier to manipulate......"

Xiao Yu still answered easily, and said thousands of words in one breath.

At this moment, Elder Tang was slightly surprised, hiding the joy in his eyes.

Zhao Chun was also surprised, he thought that Xiao Yu was just a grandstander, and he was just looking at the content of the book, but he didn't expect that he seemed to really remember a lot.

Several subsequent questions were also answered by Xiao Yu smoothly.

Tang Feng's questions are also more profound and complicated, but these are difficult for Xiao Yu.

After a while, Elder Tang Feng's questions also shifted from "Basic Material Matching" and "Basic Furnace Opening Method" to "Basic Fire Control Heart Technique".

"Basic Fire Control Heart Formula" is esoteric and complex, and if you don't understand the pharmacology of materials, you can miss a thousand miles.

However, Elder Tang mentioned several questions about the Basic Fire Control Heart Technique in a row, but none of them stumped Xiao Yu.

Zhao Chun's expression was sluggish, and several questions about the "Basic Fire Control Heart Technique", even if he was familiar with pharmacology since childhood, he couldn't completely answer them correctly.

Finally.

Cold sweat oozed from Elder Tang's forehead.

At this moment, he didn't know whether it was embarrassment or surprise.

Facts have proved that Xiao Yu has indeed basically learned the content of "Basic Material Matching" and "Basic Fire Control Heart Technique" in just one morning.

Such a perverted memory, almost a demonic existence.

"One last question. ”

Elder Tang took a deep breath and said solemnly, "Since you have basically comprehended the 'Basic Material Matching' and the 'Basic Fire Control Heart Technique', then I will let you analyze the material matching principle of the 'Snow Spirit Pill'." Regarding this Dan, it is mentioned in "Basic Material Matching" and "Basic Fire Control Heart Formula", and the material formula is also available. ”

How do you match materials?

Zhao Chun on the side couldn't help but gasp.

This question almost touches on the core of alchemy.

Many skilled alchemists have mastered their own "formulas", which involve the combination and integration of pharmacology, attributes, and material properties.

Although the Snow Spirit Pill is only a relatively simple elixir, and its formula is not complicated, for a newcomer who has just entered the medicine path, this problem is completely difficult.

A newcomer to alchemy who has just started has not even mastered the common material properties and property rules, let alone the actual principle of material matching?

When this question was raised, Xiao Yu also fell into a short thought.

Elder Tang sighed secretly in his heart, is this question too ruthless?

The people who can successfully answer this question are basically official alchemists.

"The hundred-year-old cold ice and snow lotus, the attribute is yin and cold, containing the essence of heaven and earth, this is the first main material of the 'Snow Spirit Pill'; the brain marrow and essence blood of the red fire linhu contain red flame crystals, partial yang blood, rich in fire attributes, can neutralize the cold of the hundred-year-old cold ice and snow lotus, this is the second main medicine; the hundred-year-old branches and leaves, have the effect of clearing the brain and calming the mind, fusing the first two, you can add the effect of calming the nerves......"

Xiao Yu explained the properties and coordination principles of a total of 27 kinds of materials one by one.

When he finished analyzing everything, he left Elder Tang and Zhao Chun dumbfounded.

After a long time.

Elder Tang let out a long breath and glanced at Xiao Yu deeply: "Very good answer! This question is beyond the scope of our agreement. ”

How could he not understand that the last question was beyond the limits of the agreement.

Elder Tang's intention was to suppress Xiao Yu's arrogance, but unexpectedly, Xiao Yu not only had an amazing memory, but also a first-class comprehension.

Because this last question, just rote memorization, cannot be answered so comprehensively.

It seems that this son's talent in alchemy can only be described as terrifying.

With his decades of life experience, he has seen so many geniuses, and naturally knows that there is a kind of genius that "never forgets".

Unexpectedly, this little guy really has such a talent.

The ability to never forget is what many people dream of!

Because this ability can allow a person to study hard for months or even years in just a few days.

Even if it's just a pig, with this ability, it can become a fighting pig.

It is no wonder that Xiao Yu was able to memorize all the "Pharmacopoeia" that others could memorize in a few years, creating a record for the entire southern Xinjiang.

Thinking of this, Tang Feng's anger disappeared, and only excitement and excitement remained in his heart.

Perhaps, is it really providential?

Tang Feng was quite excited in his heart, but quickly calmed down again.

He sighed, flipped through his right hand, and a thick quaint scroll appeared in his hand.

Tang Feng put the scroll in Xiao Yu's hand and left a sentence: "You have mastered the basic alchemy, this is the Intermediate Alchemy, you can watch it." ”

Then he turned and went upstairs, leaving Xiao Yu standing alone in the empty hall.

"Ding! The host completes all the theoretical learning of the primary alchemy and activates the primary alchemy. ”

The cold voice of the system sounded, Xiao Yu was stunned, he opened the interface of the mirror system, and saw that the originally gray place spread out like the fog of war, revealing the alchemy on it.

"Elementary Alchemy: Proficiency 0/100. ”

Xiao Yu was a little puzzled, what was going on?

"Why wasn't there before?" Xiao Yu still subconsciously asked the system, but as a result, there was no response.

"Okay. Xiao Yu rolled his eyes, he was thinking, maybe he had to learn all the basic alchemy techniques to activate it.

Xiao Yu touched his chin with his left hand and asked unwillingly, "Brother System, if you upgrade to an intermediate alchemy, what are the benefits?"

After being silent for three seconds, Xiao Yu's voice finally sounded in his mind: "You can obtain the transformation value, and the alchemy yield will also increase." ”

Xiao Yu's eyes lit up, and he obtained the transformation value, and improved the yield rate.

This is simply against the sky!

Xiao Yu almost jumped up, didn't this mean that as long as he made alchemy, he could upgrade?

However, accustomed to the "pit man" of the system, Xiao Yu quickly came to his senses and asked cautiously: "Brother system, how do I need to improve my proficiency?"

There was another silence, and just when Xiao Yu thought that the system would not answer, a cold voice sounded again.

"Refining a high-grade elixir or a higher-grade elixir, and the finished product rate reaches more than ninety, and the proficiency is increased by one. ”

Listening to the system's answer, Xiao Yu almost burst into foul language.

Although he had a hunch that it would not be easy to improve his proficiency in alchemy, Xiao Yu did not expect it to be so difficult.

You must know that it is not easy for an average junior alchemist to achieve a yield of sixty percent.

And this system actually needs a 90% yield rate to improve proficiency?

What a trick!

"Ninety percent yield? Brother System, are you sure?"

Xiao Yu was unwilling and asked again.

This time, the system fell into a long silence, leaving only Xiao Yu holding the "Intermediate Alchemy" in his hand, wanting to cry without tears.
