Zhuge Pingyun came to the center of the square and beckoned to Zhang Ping, "Zhang Ping, come, I'll refine an ordinary long sword, you take a closer look, if there is anything you don't understand, you can write it down first, and then explain it after I finish refining." ”

Zhang Ping nodded, with a look of respect: "Thank you, senior brother." ”

Zhuge Pingyun's face was arrogant, "This is a virtual memory space, and some steps can be omitted." For example, the material properties and formations that already exist in your memory can be realized instantly.

But I'll take it slowly, from the beginning, you look closely. ”

Zhang Ping nodded, and even turned on the recording function.

Zhuge Pingyun had a lead-gray metal block on his hand - this is the legendary 'shit iron'.

This is actually a mixture of some scrapped magic weapons, magic weapons, magic weapon mechanical parts, etc.

Generally, the discarded magic weapons will be simply recycled and re-extracted from the expensive spiritual metals in them, such as dark iron and red copper. But this refining effect is not good, and a large amount of spiritual materials are directly melted into scrap iron.

This kind of scrap iron is officially called 'gray iron', and the folk call it 'shit iron'.

It's not that it can't be refined, but industrial production has to consider the cost. The cost of refining is a bit high, except for a very small number of expensive spiritual materials, most of them are not as good as mining new mines.

And even if it is shit iron, the price is not low, and it is very useful, and it is not easy for ordinary people to buy it.

For example, the foundation part of the teleportation array, such as the platform foundation of a trackless train in urban construction, the exterior wall and foundation of a bank vault, or the construction of weapon models by some military enterprises, as well as college students and laboratory consumables. There are also some luxury materials.

In short, Zhang Ping really hasn't used this thing. Although he had a lot of experience in refining weapons before, the best thing he used was only the claws and toes and teeth of demon beasts. The rest are all ordinary mortal iron.

In the past, Zhang Ping was too ordinary, and he officially started refining weapons, he entered the Longshan Cave Heaven to practice, and then he was exiled to the space, and he has been busy until now.

Fortunately, Zhang Ping is not ordinary now.

Zhuge Pingyun first used real fire to calcinate materials, and his mouth was verbose: "Calcining materials with real fire, in addition to melting materials and reshaping, there are two main purposes.

First, cleaning. Those who don't know say that refining tools should first purify materials and remove impurities. But such a statement, just know what it is, don't know why it is, it's all the same.

In fact, there are deep principles involved in it.

First of all, what is real fire? Why do ordinary cultivators have to be after the golden pill period to give birth to true fire?

Actually, to put it bluntly, it's very simple. True fire is an extremely pure energy, a phenomenon that naturally arises because of the purity, purity, and sufficient spiritual pressure in the body of a Jindan stage cultivator.

In other words, theoretically, as long as the internal qi, true qi, true element, and even mana are pure enough, and there is enough spiritual pressure, even ordinary people can give birth to true fire.

Of course, theory is theory after all. Only the body in the foundation building period can barely produce enough spiritual pressure.

So know why we were surprised. You actually gave birth to true fire in the Qi Refining Realm! You're not a genius, you're a monster. ”

Zhang Ping didn't speak, just listened quietly. Although he had been refining weapons before, he had really not studied the theories of refining weapons, true fire, etc. Because these theories are clearly not public.

Zhuge Pingyun continued to ramble: "Let's talk about materials and impurities. Taking steel as an example, the purity of materials produced by our industry can generally reach three nines, that is, 99.9%. Some of the high requirements can reach six nines, or even twelve nines.

But why does this steel continue to shrink after being refined with real fire? ”

Zhang Ping spoke: "Isotope." ”

"It's only a little bit, but it's not enough, it's not enough. Let's take a chestnut.

[Zhuge Pingyun used an emoji, and a cat's paw appeared next to him and raised a big chestnut]

"People on earth are all human beings, and everyone can intermarry with each other. But if China wants to form an army, what will it do?

Those who can choose Chinese nationality, are in good health, have passed the political examination, have a good education, are diligent, brave and persevering; And then you have to sift through it as well.

As for whether this person is pure Chinese national blood, beautiful and ugly, fat and thin, male and female, etc., it is secondary.

In the refiner, different races are similar to isotopes. But the material world, atomic structure, etc., is not so simple.

It is the same iron atom, and the composition is the same from a macroscopic point of view. However, if you dig deeper, you will find that some iron atoms are more energetic and active, while others are less active. If you look at the nuclei, you will find that the rotation speed of the nuclei is not the same.

If you go into the nucleus to observe, you will find that there is a slight difference in the arrangement of protons and neutrons inside each iron atom.

If you enter the proton neutron observation, you will find that there are different quark structures.

Ordinary people will take it for granted that since they are all iron atoms, they should all be the same. However, this could not be more wrong.

Not to mention iron atoms, even photons, no two are exactly the same.

No two leaves in the world are exactly the same. This principle applies to almost the entire world. Whether it is the basic material world, or the world of dark matter and dark energy. ”

Zhang Ping nodded seriously. "I see, teachable."

Zhuge Pingyun continued: "Back to the first purpose of the True Fire and Refining Weapon.

True fire is a kind of energy that is pure to the point of qualitative change, a kind of advanced energy, which can penetrate into the inside of atoms, and even into the nucleus.

The so-called refining materials are to use real fire to clean and filter materials. The atoms that match the characteristics of true fire are left behind, and the rest are expelled. ”

"And then there's the second point. Empowering.

After expelling the atoms that don't meet expectations, the remaining atoms are what we need. In the eyes of non-specialists, it is the so-called 'essence'.

But at this time, the essence is still dead, and it needs to be activated, that is, recharged, injected with true qi and even spiritual power. And that's the second purpose of True Fire.

The reason why there are so many magic weapons lies here.

The energy of the true fire can penetrate into the nucleus of the atom, or even the inside of the proton neutron, and give the atom energy, fundamentally changing the properties of the atom, and then making the magic weapon semi-energetic, or even fully energized.

For some powerful cultivators, their true fire energy can even penetrate into quarks and quantums, allowing matter to be completely energized.

From the perspective of scientific classification, true fire, true qi, etc. belong to the dark energy part. In this way, the magic weapon of energy can be integrated into the human body and coexist with the human body without being visible.

This is the analysis of the material level of the refining of the magic weapon. ”

Zhang Ping suddenly realized, and there was infinite enlightenment in his heart.

Sure enough, it is not possible to grope alone, and the kind of people in the movie who can rise with cheats are all deceitful.

These professional knowledge, without the imparting of professional knowledge, even if the layman wants to be blind, should not know or not know.

Behind these seemingly simple knowledge, a huge scientific research system is needed to study and verify. If nothing else, ordinary people, you can dissect a nucleus for me.

As he spoke, Zhuge Pingyun had finished refining the materials and continued to ramble: "Below, is the formation." ”

Zhang Ping's ears were completely erected. Although Senior Brother Zhuge is a little nagging, it's good, I like it.
