"First of all, you have to know what alchemy is?"

It's right in the back alley of the bar.

Xu Lai instructed Ziliang to seal the back door of the bar.

Even that didn't stop the three from getting here, but it did delay a little bit.

Even, as long as he wants, he can completely save some things.

But since they have found Vincent, there are some things that still have to be solved after all.

But the best solution is not to give people fish, but to give them fish.

Especially for Van Gogh, who lacked parental love since he was a child.

"Seriously, silly boy, I'm teaching you how to defend yourself, not self-defense, do you need to think about it for so long?"

Xu came to remind that Van Gogh was still confused.

"You've got to tell me about the theory!"

Van Gogh said: "I need to understand some basic theories before I learn to paint!" ”

"Then you have to remember, I'll only teach you once."

Xu said, "First of all, you have to know the difference between alchemy and alchemy. ”

"This alchemy is a technique for refining pills in ancient China, and it is the forerunner of modern chemistry. At the earliest, it was just a product of delusion and imagination, and it was a technique gradually formed in the process of the royal family's search for the method of immortality, so it could not be called true alchemy. Later, after countless generations, the alchemists who understood the flow of all matter in the world and corrected the flow called it the dragon vein. As long as this flow is understood, alchemy can be used. In other words, as long as there is something in flux, even if the object is a human or artificial object, alchemy can be used on the object. Although alchemy is mainly used for medical purposes, it can be said to be a technique for restoring substances that have been damaged in the same way as healing the human body. The final step of alchemy can be defined as a step close to regeneration, as opposed to the last step of alchemy. Alchemy is characterized by long-range alchemy. and artifact refining. It would be nice for you to know about this one, after all, I already have a very good alchemist under my hands. ”

"As for the alchemist, I should consider summoning the brothers Edward and El after this time journey, but that's another story. But before I go back, you can learn some as a skill for self-defense in the future. ”

"This alchemy is the thought and ancestor of a chemical philosophy in the Middle Ages, the prototype of contemporary chemistry. Its goal is to chemically convert some base metals into gold to make a cure-all and prepare an elixir of life. Science shows that this approach doesn't work. You just need to remember that alchemy is a technique that can change the composition and shape of matter and create another substance. The basic principle is equivalent exchange, and the quality and elements of the raw materials and the refined substances must be the same, so it is not possible to refine metals from water. However, because there are many metal elements in the earth, such as aluminum and iron, most alchemists of the fighting school can use local materials to create a variety of weapons. ”

"The process of refining is divided into three steps: understanding, decomposition, and recomposition."

"The difference with alchemy is that it can only be refined at short range. This requires the alchemy array, this is the point, and we will talk about it later. ”

"Second, it is important to abide by the equivalent exchange choice. This principle of equivalent exchange can be said to be the core of alchemy. It refers to a substance of the same mass and value, which can only be produced by alchemy after alchemy. It also means that in order to be successful, there is a corresponding price to pay. This is the 1:1 substitution principle. ”

"Then it's a refining formation. It generates the energy required for refining - the power of the circle. All the refining arrays are based on the circle type. There must be a center point in the circle, and the upward force that gathers from the circumference to the center point is the cycle of power = the power of consent. In addition, the circle also indicates the time cycle required during the refining process or operation. ”

It is a construct that expresses the process required for refining and the composition of matter. A construct is something that represents the composition and refining process of matter. From the perspective of modern learning, it can be seen as a chemical equation. After combining the structure with the circle, the formation is completed. Then, the alchemist sends the idea into the alchemy array, and the alchemy can be initiated. ”

"Each alchemist's alchemy array design is different, and even if you want to refine the same thing, the alchemy array drawn by each alchemist will be different. Some alchemy arrays will be composed of pictures and words, while others will be composed of simple formations, and this is because each alchemist's understanding and construction method are different, so countless alchemy arrays will be thought of. The better the alchemist, the simpler the alchemy array can be used to carry out complex alchemy.

"The next step is to put the raw materials in the center of the array, and the energy generated can be used efficiently without wasting anything. Even if there are other substances that are wrong in the refining array, as long as they are not included in the structure, they will not be directly affected. Because of this, when the energy provided by the material in the refining is not enough to maintain the alchemy, then the alchemist must lose part of his body at the cost of refining the rebound. ”

......

After the introduction of theoretical knowledge.

Xu Lai stretched out his hand and snapped his fingers, and a paintbrush in Vincent's pocket immediately flew out and fell into his hand.

Xu Lai immediately dipped his saliva with a paintbrush and drew a simple refining array on the ground.

He told Van Gogh to look carefully.

"This is the Flame Array, this is the Ice Array, this is the Wind Array, this is the ......"

"It is important to remember the principle of equivalent exchange. If you want to summon fire, you'll need to prepare something equal to the flame, such as oil, or wine! ”

"If you want to summon ice, you can prepare some water ......"

Vincent was very smart, and Xu Lai also taught him in the most concise way.

He almost remembered probably.

So, when he was planning this fresh knowledge, he was eager to try it.

“SCP-CN-427！ You are officially notified that you have been arrested. Please cooperate with us and return to the Foundation with us. ”

Three figures appeared at the entrance to the alley.

Vincent looked at the three of them suspiciously:

"Who are they? And what will the Foundation do? ”

"A group of annoying people, an annoying organization."

Xu Lai told Van Gogh directly: "There is wine here, you can try the flame array." ”

"Just target them!"

Vincent looked at the three people who were gradually approaching.

He remembered how the flame array was drawn.

And then after the end of the strokes......

"That's it! Is it ready to start? ”

"Aim at them!"

"It's already aimed!"

"Then start!"

There was a loud bang.

A pillar of fire flew out of the refining array and swooped down towards the three Foundation members at an extremely fast speed.

......

"The information is wrong! The information is wrong! Warning, the other party is an alchemist! Again, the other party is an alchemist! ”
