The old man was so deceiving him that Carlos could only try to find an answer.

He picked up a parchment book with "The Fourth Alchemy" written on the cover, flipped through a few pages, and because he was selectively browsing, he deliberately skipped the part of the book with jerky and difficult special characters and patterns, and only focused on the material structure of different alchemy.

Flipping through several different types of alchemy, Carlos raised an eyebrow.

Sure enough, I found a very interesting phenomenon.

On the third and eleventh pages of the Fourth Alchemy, it is recorded that the alchemical composition of the four pages is extremely complex, and that there are three alchemical schemes.

Carlos discovered that they had a common denominator.

Material!

Yes, there is a detailed description of the material, the name of the material and the category, but the amount that needs to be put in the alchemy process is not clearly stated in this book.

Carlos exhaled.

What's the deal with only an approximate list of materials, but not the exact dosage required for each material?

He didn't think that this was an alchemist's estimation that he would not record it, and if the material was quantified, the alchemy process would be simplified.

Such a good thing will not be rejected unless it is a fool.

Carlos was puzzled, so he pointed to the voodoo potion in the "Fourth Alchemy" in his hand and consulted the old man,

"Teacher, why is there no specific amount of material in these alchemy.

For example, in this voodoo potion, the materials are rain flower grass, blacktail fish oil, and green-skinned lizard scales, but it is only written that the ratio is roughly 1:2:1. If there can be an approximate proportion, why can't we record a more detailed list of materials, or even how many grams of each type of material are given?"

Du Buyi's beard trembled when he heard this, put the wine bottle card on the coffee table, and asked a question: "Do you think that quantifying the amount of materials can achieve a simple replication of alchemy?"

Carlos nodded and replied, "Isn't it not? Since alchemy is a logical and meticulous technique, quantifying the alchemy materials, as long as it can be refined enough to be detailed, it can be used to perform the same amount of alchemy according to the same standard." ”

Du Buyi praised it, the same amount of alchemy is a big deal, looked up at Carlos, and asked with a strange smile: "Boy, if you can perform the same amount of alchemy, how far do you think the quantification of materials can be done?"

Carlos looked at the parchment book in his hand, rubbed his fingers on the book cover, felt the softness of the old sheepskin, and grinned: "Students think that this varies from alchemy to alchemy, some alchemy projects have high requirements for the quality of materials, and the quantification must be delicate enough, and some crude alchemy can be achieved by refining with the proportion of materials." ”

The old man pursed his lips and didn't say anything, but just took out a gray-black alchemy stone and threw it on the coffee table.

"Boy, you see, this alchemy stone is the most crude, and it is also the worst reaction sensitivity, in the next half an hour, you give me a good eye on it, and record how many times he will react in the state of not refining. ”

Carlos was generally aware of the alchemy stone, which was the substance needed by the alchemist to synthesize the alchemy material during the alchemy process, and was usually used as a medium to intensify the reaction of the material.

For example, if light travels in a straight line and is thrown into a medium, such as a thick wall, the light will temporarily change direction, and then continue to travel in a straight line after the change.

Alchemy stone is an important medium in the alchemy process.

Carlos looked at the gray and black stone on the coffee table in amazement, and said in his heart that the alchemy stone was like this, ugly and ugly.

However, since it is the most low-level alchemy stone, the reaction sensitivity is also the lowest, so it is placed on the coffee table, exposed to the air, and it is not an alchemy furnace or a reaction pool, so you can see what changes can be seen.

Carlos looked at Du Buyi suspiciously, and then at the broken stone.

I couldn't help but curse in my heart.

It also records the number of reactions within half an hour, and I think there will be no no reaction in half a year, at most there are multiple layers of ash on the surface.

As a result, within a few moments, Carlos was so surprised that his mouth was wide open enough to eat a frog.

Because he saw that the alchemy stone flickered a total of seven times in a short period of time, and on one occasion, there was an extremely rare thunder and lightning effect on the surface of the gray-black stone, and a slender white arc of electricity quickly swept over the surface of the alchemy, almost hitting the palm of his hand on the table.

There are a total of seven material reactions, without alchemy.

To be precise, in fact, in less than half an hour, the alchemy stone was proudly withdrawn into Du Buyi's arms.

Carlos' eyes were a little glazed and he blinked.

"Teacher, are you sure this isn't magic?"

The old man's face darkened, and he glanced at Carlos with great disdain, revealing an expression of disdain that you would expect.

"Hehe, the student didn't mean that, but this is too incredible, what's going on with this alchemy stone, isn't it the lowest grade alchemy stone?"

Du Buyi drank the little wine left in the bottle in one gulp and shook the empty bottle.

"Because of the air, there is a prohibition in this damn air, and any material material will produce uncertainty in the process of alchemy, even if it is the alchemy stone itself, it only needs to expose it to the air, and it will continue to produce such uncertain reactions. ”

When Carloston was empowered, he felt even more incredible.

He opened his mouth and swallowed, "Is there a ban in the air?

Du Buyi's expression was obviously much darker, and his eyes were as gray as a dead silence.

The old man shook his head, "I don't know, maybe maybe not, I've never heard of such a huge prohibition that can cover the whole world." ”

Carlos jumped to his feet, his jaw dropping in surprise.

"What, a magic ban that covers the entire world?"

Du Buyi glared at Carlos and said suspiciously, "Why are you so excited?"

"Uh, nothing. ”

Carlos sat back on the couch like a deflated ball, thinking that he had found some great business opportunity, as long as he learned one or two special and simple alchemy techniques and promoted them, he would be able to obtain a steady stream of wealth in the future, and everything would be a fantasy and a vain.

He was sad for a while, and found that Du Buyi held the alchemy stone in his arms, and he didn't seem to react, so he still didn't give up and asked,

"Teacher, isn't there any exception to this prohibition? For example, if the house is built underground, most of the air is isolated, and the air content is reduced to a minimum, is there a way to avoid it? ”

The old man stroked his beard.

"You're a clever man, but it's been a centuries-old tradition for the alchemist to have his alchemy workshop in the basement, and although it can properly stabilize the material reaction, it still can't escape the shackles of this prohibition. Speaking of this, the old man paused, his face showed a yearning look, and said: "There is only one exception, where alchemy is almost not subject to this damn air prohibition. ”

"Where is it?" asked Carlos.

"Aion. ”
