This principle was later called the principle of equivalent exchange by the alchemy world.

From today's point of view, the principle of equivalent exchange proposed by the great alchemist does not stand up to scrutiny, because the human value system is already fragile and full of contradictions, and even the price of food will vary greatly depending on the year and place of origin.

However, this does not completely negate the principle of equivalent exchange.

Although this theory is crude and naïve, it has inspired and enlightened many alchemists, and later the far-reaching law of conservation of energy, the law of conservation of mass, these great laws have the shadow of the principle of equivalent exchange.

Back to metal forging.

As far as alchemy is concerned, metal refining should actually be regarded as the origin direction of alchemy.

Alchemy, as the name suggests, is the technique of refining gold, and the original alchemists were essentially a group of visionaries who wanted to refine cheap and ubiquitous objects such as stones into gold by some means.

Gold is a type of metal, so the original direction of alchemy was metal smelting.

What makes people feel speechless is that after so many years of development, alchemy, which took metal refining as the original research direction, is still an untouchable field for newcomers to alchemy.

This is determined by the properties of the metal and the magic itself.

Metals are more susceptible to magic than gases, liquids, or animal and plant remains, which is known in alchemical circles as metal's inertness.

If you want to change the properties and structure of the metal through the alchemy array, there are only two ways, the first is to strengthen the strength of the magic power with a special alchemy array, and the second is to increase the time that the magic is in contact with the metal.

And for newcomers, no matter which one of them is quite difficult.

After increasing the strength of the magic power, the alchemy formation will make the magic more difficult to control, and controlling the magic power for a long time is also a big burden for newcomers to the metal.

"Are you really going to do metal forging?"

Long Chen still couldn't believe it, although he had seen the unfathomable side of this cloak apprentice before, but in terms of alchemy, Long Chen could be sure that the other party was an out-and-out novice, and even far inferior to many ordinary novices.

is such a novice who has not shown any alchemy talent, and suddenly proposes to challenge the crown jewel of alchemy, I am afraid that anyone who hears it will feel unbelievable.

"Do you know who owns the Ramo Iron Ore?"

Al didn't answer Long Chen's question, perhaps because he felt that Long Chen's question didn't make sense to answer at all.

"Just ask him, that black-rimmed senior over there, I saw that his alchemy was actually using raw iron ore in the morning, you can ask him if he has any leftovers. ”

Long Chen pointed to the side, a formal alchemist said to Al.

Alsey.

"Hello senior, do you have any remaining raw iron ore?"

A voice came from behind, which made Rubick, who was busy, slightly stunned.

He naturally had the impression of this voice, because he was so special, in short, there was only one person in the room who had such a voice, and that was the new apprentice who wore a cloak all day long.

"What do you want the raw iron ore for? Did Su Ya ask you to come over and help her get it?"

Rubick asked, turning around.

"No, it's my own desire to make metal into reality. ”

Al replied honestly.

"Yourself?"

Rubick's mouth was wide open, and there was a look of surprise on his face.

Although he had not dealt with this apprentice wearing a cloak, after all, the real room was only so big, and before Su Ya reprimanded this newcomer's alchemy assistant in his usual ruthless and cold voice, Rabier had overheard a few words more or less.

Obviously, the other party is not only an alchemy apprentice, but also an alchemy assistant who is quite lame and has no talent.

Why did such a person suddenly think of doing some kind of metal refining alone?

Rubick suddenly wanted to laugh.

Today's young people always want to make a big news all the time, and then criticize those who looked down on him before.

native!(Ancient Magic: Innocence)

Pushing the heavy black-rimmed glasses on the bridge of his nose, Rubick smiled meaningfully at the corners of his mouth, and said slowly, "Raw iron ore? I have some left, but are you sure you really want to use it for metal smelting?" I don't think you can do that with your current ability. ”

"Can you give it to me, then?"

"Yes. ”

Perhaps just out of the sense of jokes, Rubick finally agreed to a somewhat unreasonable request.

Al nodded in gratitude.

After getting the original iron ore, Al did not immediately start alchemizing, but walked to the side of the bookshelf and took down a large hardcover book called "Metal Alchemy Elementary", which made Rubick and Long Chen, who were paying attention to him, cry and laugh.

Even if it's just a temporary cramming and a whim, there's no need to be obvious to this journey, right?

Referring to the entry-level metal refining textbook, Al drew the first metal refining formation with one stroke.

In all fairness, this alchemy array looked very decent from the outside.

This can be clearly proved by the alchemy array pattern in Long Chencun's mind or the memory in Labik's heart.

However, this did not surprise the other two too much, after all, once the alchemy array was drawn more proficiently, even if it was a new alchemy array that had never been seen before, as long as it was drawn stroke by stroke against the standard drawing, it could always be drawn decently.

But being decent doesn't mean it's easy to use.

There are many details and pitfalls that can and cannot be described, such as the order, the thickness of the strokes, the direction of the pen, etc., which are worth exploring and experimenting with for a long time, especially when there is no one to guide them.

Unless this newcomer is the kind of talent that is terrifyingly high, his own qualifications are enough to save the zài with his strength.

But is it possible?

Apparently impossible.

If this cloak apprentice had such an ability, he wouldn't have been taught a lesson by Su Ya this month, real gold would glow no matter where it was, and if it didn't shine, then it must just be a worthless stubborn stone. (To be continued.) )
