Chapter 170 The Mystery of Yue King Goujian's Sword

For the next two days, Qin Luo stayed in this factory.

Get what you want.

The Peerless Sword, Frostmourne, and Xuan Chongru each brought one, which attracted a lot of popularity for their live broadcast.

However, Qin Luo naturally didn't use these weapons.

I don't plan to keep it in my collection either.

Originally, it was just for practice, and all lucky draws were given out in the live broadcast room.

The sharp weapon of the magic weapon is for those who are destined to take it.

This made the popularity of the live broadcast room soar to a very high level in an instant.

While doing these exercises, Qin Luo devoted all his thoughts to the project of imitating the "Goujian Sword of the King of Yue".

This sword is very famous, since it was unearthed, it has been imitated countless times, which is not really news.

However, all the previous imitation methods were imitated by modern technology. From the perspective of "ancient method", no one has ever successfully imitated.

Moreover, even the finished products imitated by modern technology are far inferior to the original Yue Wang Goujian Sword in some details.

In a sense, the status of this sword in the history of ancient weapons and even in the history of Chinese cultural relics is almost... a myth.

Before the imitation, Qin Luo also did a lot of preparatory work.

All kinds of notes alone have written more than [-] words.

On the Internet, I also checked a lot of information.

……

Where is the specific myth of Goujian Sword, the King of Yue?
First, there is the chemical composition of the material.

The main chemical composition of Goujian Sword of Yue King is copper-tin alloy.

Moreover, the proportion of copper-tin alloy is the most perfect 17% after repeated calculations by modern science, the best alloy ratio.

At the same time, the copper-tin ratio of the blade and spine of this alloy sword is actually different.

The copper element gathers on the sword spine.

The tin element is concentrated on the blade.

As if spiritual.

This involves the issue of casting techniques.

Research by later generations shows that the spine and body of Goujian's sword, king of Yue, were cast separately.

First use copper water with high copper content to cast the sword spine, and then use copper water with high tin content to cast the blade on the outside of the sword spine, thus making an alloy sword with a different copper-tin ratio.

But, even so, it is still not enough to explain the magic of this sword.

After more detailed research, the archaeologists are numb...

They suddenly discovered that from the blade to the spine, the ratio of tin is not fixed, but a gradual process of steady and gradual increase.

This is completely unimaginable in terms of craftsmanship.

Until now, it is still an unsolved mystery.

No one knows at all how the ancients did this, even in modern times, there is almost no one who can do this.

This is almost micromanipulation at the "molecular" level.

……

The second magic point lies in the anti-rust process.

The Yuewang sword has been stainless for thousands of years.

Test data showed that the sword body contained sulfur.

This is a metallurgical technology that modern technology did not master until after the [-]th century.

However, the ancients had perfectly mastered it more than 2000 years ago.

However, the point is that metal surface vulcanization treatment technology can only be used on steel and iron products, and cannot be used on copper ware.

On the contrary, copper sulfide is a very unstable compound.

Not to mention rustproof.

Adding sulfur to copper is simply corroding.

However, it happened that the Yuewang sword, which contained sulfur in the sword body, was not rusted for thousands of years.

Mendeleev's coffin was about to be overwhelmed.

……

The third bit of magic is that...

The 11 concentric circles on the hilt are less than 0.2 mm apart.

Extremely regular, extremely precise.

In modern times, it can be completely imitated, but it needs to use a five-axis machine tool.

What is the concept of a five-axis machine tool?
Five-axis machine tool, with high technological content and high precision, is specially used for processing complex curved surfaces.

It is mainly used in the processing of aerospace, military, scientific research, precision instruments, high-precision medical equipment and other equipment.

For example: impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts, etc.

If it is said that the ancients of that era mastered this technology by hand, then it basically means that a swordsmith can do it by hand rubbing the engine and hand rubbing the propeller.

……

The fourth point of magic lies in the crystal growth process.

In the process of manufacturing chips, the most difficult step is to grow crystals.

It is to let a small silicon crystal grow into a huge silicon crystal rod.

The silicon ingot is then cut to become a wafer.

This is the housekeeping secret of major chip processing factories.

However, on the Yue King Goujian sword, the long crystal process also appeared.

The thinner the blade, the higher the tin content.

Archaeologists observed with a 500x microscope and found that this was because the crystallization of metal tin appeared on the blade.

Moreover, it is the most complicated one in the crystal growth process - dendrite.

In terms of technical difficulty, its difficulty is actually not much different from rubbing chips by hand.

It's hard to imagine how this sword was cast.

This is a cross-age product that far surpassed the social productivity at that time.

……

These questions, until now, archaeologists still do not understand.

However, Qin Luo still knows a lot.

Now I am a swordsmith disciple who combines Ou Yezi, Ganjiang Moxie, Fengbeard, and the four master swordsmiths. I am naturally familiar with these long-lost techniques.

Of course, Qin Luo couldn't guarantee the reason why King Goujian of Yue could be forged.

Its formation, in fact, has certain elements of accidental factors.

Moreover, it also reveals a bit of mythology.

There has always been only one Goujian sword of the king of Yue known to the world. It is a female sword, slightly shorter, with the name of Goujian of the king of Yue engraved on it, and it is placed in the Hubei Provincial Museum.

However, everyone in the know knows that the King Goujian of Yue originally had two swords, one male and one female.

As for the male sword, it is currently locked in the National Museum and suppressed by the other two "sword spirits".

The other two swords are Helu Sword of King Wu and Fucha Sword of King Wu.

It's like... It seems that a feng shui bureau has been arranged to suppress it.

The historian who presided over the excavation of this tomb and arranged the two swords in this way is now dead, and it is impossible to know what kind of consideration he had at that time, so that the two swords were placed in such a way that they were thousands of miles away. Another "repression" should be arranged.

However, this kind of operation added a bit of mystery to the two swords.

Qin Luo was also curious.

My craft has improved to a certain level.

The amount of thinking in my mind has also reached a considerable level.

At this time, Qin Luo began to feel that it was inevitable for him to touch some essential things.

mysterious.

Or it can be called Tao.

Or it can be called easy.

Or, something more fundamental.

For this trend, Qin Luo is a little vigilant, after all, he received a materialistic education since he was a child.

But, at the same time, the heart is unavoidable, some longing.

The trend of materialistic thinking cannot represent complete truth.

Who can say that there is no such thing as "fate" in this world?

Perhaps, destiny is also an objective law that must exist.

And, it's always in motion.

At the same time, both internal and external factors will have an impact on it.

Thinking about it this way, it feels a little bit different.

of course……

Regarding this part, Qin Luo has not had the opportunity to get in touch with it yet. I don't know if it will exist in the subsequent system tasks, so that he can get a glimpse of it.

Right now, let's cast the sword first.

……

"You want to imitate the Yue King Goujian sword with the ancient method?"

Zhang Ziqi asked in disbelief, his mouth could not be closed, and his eyes looked more like seeing a monster.

outrageous.

Although, he admitted that Qin Luo did have some proficiency in sword casting.

However, it should be...probably...perhaps...it seems...too far away from Goujian, the King of Yue, right?
Is this something humans can do?
Qin Luo looked at his appearance and smiled slightly.

"Try it, how will you know if you don't try?"

"If it can be imitated...well, well, it doesn't really have any special meaning."

"There will be no tax increase, and there will be no more jobs. It's just that I am happy."

Qin Luo laughed and teased.

I ate with Zhang Ziqi for several days in a row, and listened to his lectures every day, all kinds of vocabulary, and I was a little infected by listening.

"no!"

"Don't say that. If you can really do it, Director Qin can confess you, so can I."

"The entire Longquan hand-made sword-making industry may benefit from it. Now these sword-making masters count as one, and they all have to pay for you!"

Zhang Ziqi said in an exaggerated tone.

In fact, it is not an exaggeration.

Let's just say...

Is the Longquan sword famous?

Or is the Yue King Gou Jianjian more famous?
It may not be possible to compare quantitatively.

However, if the craftsmen of Longquan can reproduce the original Goujian sword of the king of Yue by virtue of ancient methods, the news effect will definitely be popular.

For the local industry, it is definitely a major benefit.

"I'm not dead yet."

"What are you doing for me?"

"Let's do it first and then talk, maybe the car will overturn..."

Qin Luo said calmly.

In the field of sword casting, Qin Luo felt that his confidence was not as strong as that of jade carving.

If you can score...

Jade carving is a five-star hobby.

Forging swords can only be regarded as three-star.

Incense making and ceramics are considered four-star.

However, Qin Luo is a stable person. Just like when he was in school, he never favored subjects. Even though he didn't like English very much and his learning efficiency was extremely low, he still managed to get above 120 in the college entrance examination.

……

rest for a day.

Summarize all the information clearly, and go through each step countless times in my mind. All kinds of materials are ready, and Qin Luo is ready to start casting the sword.

This time, he didn't even start the live broadcast of the sword casting.

Keep it secret.

Even Qin Guangrong was not allowed to enter the workshop to check.

In the workshop, currently only Sister Cha and Yang Zi are helping.

Naturally, the live broadcast was not turned on.

at this time.

Sister Cha wore an apron and was stirring the red liquid in a large bucket.

Bloody smell.

It spread out continuously.

It looked inexplicably spooky.

This is blood.

There are four barrels in total.

They are pig blood, chicken blood, cow blood, and donkey blood.

The composition of human blood and animal blood is the same - plasma, blood cells, inorganic salts, oxygen, metabolites, hormones, enzymes and antibodies.

In addition, mammalian blood is slightly different from other animal blood.

Mammalian blood does not have nuclei, but chicken blood does.

What Qin Luo learned from the four master swordsmiths is that swords were forged with human blood, flesh and blood, and put into a furnace to become a weapon of magic weapons, but that is a slave society.

Feudal society did not do this anymore.

Modern, naturally even more impossible.

Use animal blood instead?

Qin Luo doesn't know if it's feasible, which is one of the uncertain factors.

However, you can only try it first.

Why do you have to use blood?

The reason, Qin Luo is very clear.

A sword made of iron or steel is strictly called "forging a sword". It needs to be tempered continuously, relying on the ductility of the metal to knock out the shape of a sword embryo.

However, bronze is not.

Bronze is very soft and cannot be forged. Only molten copper water can be poured into a mold to form a sword, which is then polished and polished.

Therefore, when casting bronze swords, the heat is very particular.

At the same time, how to make the copper water solidify quickly?
Rely on phosphorus.

The phosphorus element in the blood is at work, which can promote the discharge of air bubbles in the copper water, and can also enhance the fluidity of the copper water.

play some auxiliary role.

At the same time, there is sulfur.

These four barrels of blood are all added with "sulphur", which is an authentic ancient method.

It's the same as doing things.

The principle, Qin Luo guessed, is that sulfur and phosphorus will produce some strange reactions, especially in high temperature environments.

Time passed by minute by minute.

The first pot of copper water and tin water has been boiled.

During the entire firing process, Qin Luo was watching intently to grasp the various experimental data more precisely.

The mold has already been made.

Before pouring, Qin Luo took a large measuring cup, scooped [-] milliliters of donated blood, and poured it into the hot copper juice.

The unique smell produced by burning blood came out immediately, even though he had already put on a mask, Qin Luo still felt very uncomfortable.

Really bad smell.

And this time.

Sister Cha and Yang Zi stood far away, looking at them in shock.

This casting method really looks like some kind of evil sacrificial ceremony.

Strange to say, after the blood was poured in, the boiling of the copper water became more intense, and bubbles burst out, and Qin Luo poured it into a special mold.

In the mould, a special ointment had already been applied by Qin Luo on a certain edge.

Here's the recipe.

Untold secret.

Ou Yezi's secret recipe is different from Ganjiang Moxie's secret recipe, and Fengbeard's secret recipe.

However, much the same, they also have the same effect.

That is—"metal paste."

Metal paste is a paste with natural adhesive and high-tin alloy powder.

Apply to the area of ​​the metal surface to be coated, then heat, and after diffusion, a tin-rich crystalline layer can be formed.

This may be the key reason why the original version of "Goujian Sword of the King of Yue" can produce long crystals.

The microscopic world is really too mysterious.

Qin Luo can't explain the principle of it with scientific methods for the time being.

Maybe quantum mechanics can't explain it.

He is still trying.

at the same time……

Qin Luo is still thinking about another question...

During the Spring and Autumn Period and the Warring States Period, was the oxygen content in the air different from the present?
Will there be a different reaction?
Hard to say.

More data support is needed.
