Human civilization originated from the use of tools, and it is precisely because of learning to use tools that human beings are gradually distinguished from animals, and civilization is gradually derived.

The introductory part of the book details how the monk went from using stone and wood to smelting metal.

However, these introductory parts were artificially separated from the subsequent foundational texts and formed into a separate volume.

Because of the support of the formation, the hall of District C3 was spotless, but Xu Chen still saw the loneliness and sadness of this volume between the spotless pages in his hand.

It is very understandable that in this era, there are very few monks who specialize in refining weapons, and among this group of rare refining scholars, there are even fewer who are really willing to calm down and study this "Initial Solution of Refining".

And the introduction of this volume is even more meaningless to them, how can they waste time on this when they are pressed for time?

It is also a habit left over from the previous school days, Xu Chen always likes to start from the introduction part when he reads, so as to find the context of the full text and achieve a strategic position.

This time, the same is true of Tianxin.

After looking at it for a while, Xu Chen found that these knowledge that should be unfamiliar are so familiar!

In addition to the first introduction, according to what Qin Feng said, "The Preliminary Solution of Refining" is also divided into three parts: raw materials, smelting, and runes.

In the introduction, in addition to introducing the derivative history of alchemy, the principle of alchemy is explained in detail.

The so-called refining is the process of reprocessing raw materials.

Initially, the shape of the material was changed by grinding, but later, the composition of the material was analyzed in depth to remove impurities from the material to obtain a higher purity material.

Later, the monks learned to use the properties of various materials to find a way to combine two, three, or even multiple materials to make the structure stable, so as to obtain a new type of material that could meet the different needs of the monks.

This process is called "smelting"!

Before smelting, the refiner needs to have an extremely deep understanding of the various materials in order to be able to know it in his heart and at his fingertips.

A refiner with deep enough qualifications must also have extremely solid basic skills!

In this regard, in the raw materials chapter of "The First Solution of Refining", only more than 1,000 common materials are recorded, and the new materials that were discovered and proved in the later period naturally became the private collection of each refiner, and the understanding of new materials has become an important basis for measuring the refining level of a refiner.

After reading these, the four big words "metal smelting" popped out of Xu Chen's mind almost without thinking!

The so-called smelting and smelting metal are no different at all!

Xu Chen is a liberal arts student, and he only knows a little about engineering topics such as metal smelting, which are all extremely superficial things!

However, these things are a high summary of the more than 3,000 years of metal smelting history of later generations!

Only the things closest to the origin can be passed down through the ages, and only these seemingly superficial things can be accepted by even ordinary people.

Xu Chen is very lucky!

He originally had a summary of metal smelting in his mind, but he lacked a specific and detailed understanding.

However, the book "The First Solution of Refining Weapons" in front of me contains all the refining knowledge of the cultivation civilization from scratch and from simple to complex, which just makes up for Xu Chen's shortcomings!

Moreover, the crystallization of wisdom produced by two different eras and different civilizations collided for the first time here in Xu Chen!

Many problems that cannot be solved by monks are common knowledge in later generations, and conjectures that cannot be verified by later generations can be easily confirmed with the power of monks!

Xu Chen felt that he had picked up a great treasure!

The accumulation of civilization over 10,000 years, where is not a treasure?

Time passed little by little, but Xu Chen didn't notice it at all, completely immersed in the huge beauty generated by the intersection of civilizations!

It's like an old man who has devoted himself to studying, and once he has an epiphany, everything comes to naught!

The short-term pleasure generated by the first meeting of the two civilizations made the learning efficiency unprecedentedly improved, but Xu Chen also knew that this state could not last long, and it was only once in this life!

For this reason, Xu Chen just skipped the "material chapter" in a hurry, these things need time to accumulate, and precious time must be put on the understanding of those esoteric theories!

After reading the process and principle of smelting in detail, and directly skipping the actual operation steps, Xu Chen came to the most critical part of alchemy, which is also the rune part that distinguishes alchemy from ordinary metal smelting!

According to Qin Feng's words, the first monk imitated the rules of heaven and earth, condensed the power that originally belonged to heaven and earth in a small rune, and then used the energy of guò aura to stimulate the aura trajectory diagram!

Runes can be said to be the root of monks!

The most fundamental strength display modes of several cultivators, such as refining weapons, talismans, and formations, are all inseparable from it!

Even the cultivator's cultivation itself, the aura runs in the veins, how can it not be a different kind of rune?

No matter how the monk understood the runes, after Xu Chen read the principles of the rune parts, Xu Chen only felt that the runes were a kind of trajectory of energy movement!

Reiki, this unique energy of the monk, is precisely the trajectory depicted by the guò runes, and then the corresponding power is generated!

When the aura completes the "light feather" rune, the carrier depicting the "light feather" can obtain a floating power out of thin air, so that the carrier can fly.

Increasing or decreasing weight, changing size, expanding space, and more!

The aura is invisible and formless, and the monk can perceive its existence, and can also ingest it into the body to use it, and even use the corresponding spells to stimulate it to produce powerful power.

However, the aura itself does not have a fixed form, and the spirit stone is just a special ore containing the aura, and it is not a solid aura!

As for the spiritual vein, it is the root of the generation of spiritual energy, and it can be regarded as a specific form of spiritual energy.

However, the search and capture of spiritual veins, even ten thousand years ago, when the cultivation civilization was prosperous, was an extremely technical job!

And now, in the era when the spiritual veins are drying up, finding and migrating the spiritual veins has become the most urgent priority for the major forces!

However, how can this scarce resource be so easy to find?

The appearance of each new spiritual vein is accompanied by bloody rain, and it is also the only reason for war for monks today.

In the "First Solution of Refining Weapons", there is a record of something called "Lingquan", which is a kind of thing similar to a spiritual vein that can produce spiritual energy on its own.

However, this kind of thing, which does not need to be transformed through the guò formation and can be directly used by people to ingest spiritual energy, has long become a legend in this year, which is more scarce than spiritual veins.

……

The law of the operation of aura in the runes is a very profound subject, even among the cultivators, only the kind of extremely experienced master can roughly grope some fur with years of experience.

It can be said that nowadays all refiners can only refine their weapons based on existing runes, and simply depict various runes on the smelted rough blank.

Why is this happening?

That's because no one can capture the movement of the aura in the runes these days!

The aura runs in its own body, and of course the monks can forcibly change the trajectory of the aura by means of exercises, spells, and other methods, and even change the original trajectory through guò to create new exercises and spells.

But once they tampered with the existing runes, they didn't know how to pull back the chaotic aura. After all, the aura in the rune is not in one's body, and it is extremely difficult to capture it, so how can you change the original trajectory?

In other words, once the rune pattern is changed and the original movement trajectory is lost, the existing refiner will not be able to create a new movement trajectory for the aura!

If you can't even make changes, how can you talk about innovation?

This has also created a rune line, which is extremely slow to develop!

For thousands of years, there may be a few amazing geniuses who, by various coincidences, accidentally changed the original runes, and then created new runes.

Once such a person appears, there is no doubt that it will shock the entire cultivation realm!

However, such people may have existed before the great changes in heaven and earth, but in the past 10,000 years, they have never heard of it!

This also directly leads to the rune chapter of "The First Solution of the Refining", which has not changed in the slightest in the past 10,000 years!

One thousand two hundred and fifty-six basic runes do not increase or decrease!

The gap in the level of a refiner's runes is completely based on the familiarity with various runes and the success rate of depicting runes, and no one dares to modify the existing runes, let alone innovate!

However, after seeing these strange-shaped runes, Xu Chen couldn't suppress an impulse in his heart!

Reiki is intangible, so the Reiki that operates outside of the human body is elusive.

However, Reiki is undoubtedly also an energy!

As for the capture and utilization of invisible energy, cultivators can't find a good way, but Xu Chen just knows a method that will be taken for granted in the eyes of future generations!

That's right! That's electricity!

Electricity, too, is invisible!

The electricity of this era is still the most primitive thunder and lightning in nature, and the energy of thunder and lightning is also a kind of natural force that is admired by cultivators!

However, with the exception of the Thunder Root Cultivator and the Thunder Ability, it is even more difficult for ordinary monks to control and use it, even if it is just to capture and store!

But......

It is as difficult as a matter for a cultivator, but it is not a problem for Xu Chen at all!

Whether it is the generation, collection, control, and utilization of electricity, it is simply too easy for Xu Chen!

In particular, the trajectory of electricity, wires, circuit diagrams, semiconductor boards, etc., originally relied on the technical level of the outside world, and it would take hundreds of years, but with the help of the power of monks, it can be quickly created!

Similarly, the operation of electricity gave Xu Chen a good inspiration!

The so-called runes are not the trajectory of the aura, and the circuit diagram is also the trajectory of electricity, and there is a striking similarity between the two!

At this moment, Xu Chen clearly saw the scene where all the runes were used for himself!

At this moment, the art of alchemy is no longer mysterious, nor is it difficult!

At this moment, the new wisdom generated when the two civilizations converge will shine in Xu Chen's hands!
