Chapter 647: Flying sword or flying knife?

The experiment was successful!
But Chu Fei did not stare at the suspended copper skin at first, but stared at the seeds of the tree of wisdom in the consciousness space.

However, at this time the seeds of the tree of wisdom began to become lazy again and began to rotate slowly.

Chu Fei stared for a long time, without any change, and finally could only say "thank you" softly.

Then Chu Fei stared at the copper skin in front of him again: this copper skin is 2 cm wide, 30 cm long and 2 microns thick.

The copper skin is only 2 microns thick, as thin as a cicada's wing - the thickness of a cicada's wing is 1 to 5 microns.

Such a thin copper skin feels like it could be blown apart by a strong blow. But even such a copper skin is now extremely hard.

Chu Fei picked it up and waved it. It was as hard as a steel plate, but it was very light.

However, the energy contained in the copper skin was slowly dissipating, and it gradually became a little softer. After Chu Fei injected energy again, it began to become stronger.

After thinking about it, Chu Fei took out his broken sword, which was made of atomic array material.

He swung the copper sheet and chopped it down. There was a sound like cutting wood. The seemingly fragile copper sheet cut into the broken knife like a steel knife, and the cutting edge was 2 centimeters deep.

The broken sword, which should have been hard, was like wood. The width of the sword was only 4.2 centimeters!

This is because Chu Fei didn't use much force.

Pull it out, hard...

With a clang, the sword was cut off.

Chu Fei was actually somewhat shocked when he looked at Guanghua's incision.

The material of this broken knife is atomic array material, which is the hardest material known so far.

As for red copper, its hardness was the same as that of ordinary metallic copper, and its skin was so fragile that it could be broken by a breath of air.

As a result, it was just a matter of "drawing" a simple manifold on the copper sheet, and it changed.

"I see. This is the correct way to smelt a magic weapon."

First, there must be high-dimensional ink—life energy, or something similar;

In fantasy cultivation, special essence, the introduction of heavenly thunder, and even sacrifices are often required, which is probably the search for "ink";

Secondly, there must be a special "writing" method. The legendary seal carving array method is probably like this;

Just now, in the process of "drawing", we have to follow the inherent energy channels and structures in the copper skin, and even make fine adjustments, and also achieve resonance, which is the resonance of the properties of the red copper itself and the properties of the seal carving. In scientific terms, it is "compatible"... probably;

Finally, there must be a formation structure, which is a manifold.

There are also many details that Chu Fei needs to explore bit by bit.

But at least the initial experiment was successful.

As long as the first step is successful, Chu Fei can continue to iterate and soar into the sky.

Close your eyes and recall everything that just happened.

The most difficult part is seal carving. You need to feel the properties of the material, maintain the manifold, and keep the material properties and manifold compatible, while also keeping the energy contained and not reducing the dimension.

After thinking for a long time, Chu Fei took out 10 grams of red copper again and repeated the previous action. But this time Chu Fei only prepared 0.1 mm copper skin instead of 2 microns.

Finally, a copper sheet measuring 2 x 60 cm in length and width was produced.

The area of ​​this copper sheet is a bit small, so Chu Fei needs to change the engraving method.

After thinking about it, Chu Fei tried to use a curse - how about I directly use the curse to project the "formation" onto the copper plate?
After trying it, he found that it was a bit difficult for the curse to attack metallic copper - no matter how soft copper is, it is still metal. Now Chu Fei's curse is limited in strength and can only explode brains.

"I can only start engraving. It seems that I need to make special tools. Come on, then."

Although there are difficulties, there are always more solutions than difficulties.

It is actually not difficult to make special tools. It is to make a "needle" that can conduct life energy - which can be understood as a seal carving pen.

It was still made of red copper and was quickly made. They even added diodes, triodes, capacitors and other structures to the "seal pen" to increase stability, amplification, and focusing effects.

In just one hour, Chu Fei made a seal engraving pen with an accuracy of up to 0.01 mm!

"Come on, let's make a real magic weapon first."

Putting the new copper sheet in place, Chu Fei's eyes were sharp, and his keen gaze could distinguish a resolution of 0.005 mm or even finer.

It was the same manifold, but this time Chu Fei took three hours to complete the engraving.

When the last stroke was completed, an ultra-thin machete blade appeared in front of Chu Fei, and it was only red copper in color.

As Chu Fei injected energy into it, the machete was suspended in mid-air, with a faint glow flowing on its surface. Because the thickness had increased, it was obvious that the energy injected had increased, and the circulation was faster.

Holding the blade, he cut at the broken knife, cutting through iron like mud!
The results of both experiments were very good, which showed that the first attempt to refine the magic weapon was a success.

However, this success can only be regarded as a "laboratory result". There is still a long way to go before it can be truly transformed into a truly industrialized product.

For example, a sword must be at least 1.2 meters long, 1 centimeter thick, and 0.8- centimeters wide. Even if the material strength is improved, the thickness can be reduced to centimeters. It cannot be lower, otherwise it will affect the feel.

Even if it is 0.8 cm thick, and each layer of copper is calculated at 0.01 mm, there are 800 layers!
Of course, the specific thickness of each layer still needs further research.

The thickness is too thin, the passing energy is too low, the strength is affected, and the processing difficulty increases;
However, if the thickness is too great, resulting in too few stacked layers, it will also affect the final quality of the magic weapon.

In the practice of fantasy, one magic weapon often has one layer of formation engraved on it. At most, the blade may have two layers of formation engraved on both sides.

But scientific practice cannot be so primitive.

Many years ago, circuit boards could have more than 100 layers. As for chip stacking technology, it started with 300 to 500 layers.

Now it’s no problem to make an 800-layer circuit board (magic weapon).

In short, the ultimate strength, cost, production difficulty, energy consumption, manifold structure and coordination of the magic weapon must all be considered comprehensively.

This requires entering the virtual space for iteration.

After Chu Fei carefully studied the current experimental product, he prepared copper sheets of more than a dozen thicknesses and engraved a variety of manifolds. He studied it for two days and collected enough information.

Two days later, Chu Fei packed up all his belongings, left the laboratory, and went straight back to the secret room to start using the virtual computer to deduce and iterate.

Half a day later, after tens of thousands of iterations, Chu Fei entered the laboratory again and began to study the magic weapon.

After iterations, Chu Fei developed the "Magic Weapon 1.0" technology.

The thickness of each layer is designed to be 0.012 mm, with a straight blade shape. The thickest part of the blade is 9 mm and the thinnest part is 6.4 mm. The widest part of the blade is 44 mm and the narrowest part is 32 mm. The overall length is 1.3 meters and the weight is about 2.5 kg.

It was a lot lighter than expected, mainly because the strength of the magic weapon was beyond imagination.

But in addition to the straight sword, Chu Fei also designed a long sword with similar data, but the length is only one meter. Because the sword is sharp on both sides, the actual weight is only 2 kilograms.

The reason I designed a long sword is because... it looks cool.

Even though many people complain about the longsword, it is really cool to use it.

Well, that's just a minor reason. There's a more important reason - fluid mechanics.

Compared to the long sword, the shape of the sword is more suitable for fluid dynamics.

As Chu Fei's training increased and his combat speed increased, the turbulence caused by the blade could not be ignored. Especially when the blade speed exceeded the speed of sound, the shock wave caused had begun to affect the stability of the blade.

But the sword can avoid this result.

This turbulence can be simulated by quickly sliding your palm through the water.

But if it is a sword, there will be no feeling when it passes through the water quickly.

But here comes the problem: swordplay is really hard to learn.

A stick for a month, a knife for a year, a gun for a lifetime, and a sword to carry with you at all times; these are the experiences summed up by the older generation over thousands of years.

If you want to practice the long sword well, you should hold it while sleeping. It is no longer a weapon, but a companion.

Moreover, sword culture occupies a considerable proportion in the Yanhuang civilization.

A sword is sharpened by grinding. It takes ten years to sharpen a sword. When the sword is removed, it is laid across the knees. To rely on the sky for thousands of miles, a long sword is needed. To travel the world with a sword, one can be wild and reckless. One sword can freeze fourteen states...

Sword culture has actually already constituted one of the three souls and seven spirits of the Yanhuang civilization and is a part of the soul.

The sword also implies the ultimate truth of Yin and Yang and Tai Chi. The shape of the sword perfectly matches the Chinese character "Zhong".

At the same time, "sword" also coincides with the ancient "innate thought" of the Yanhuang civilization.

Innate thought refers to the thought before the maturity of the Yanhuang civilization, a kind of thought that we are born with.

The sword is upright, implying the idea of ​​reaching the sky; the sword has two edges, which can hurt others as well as oneself. There is a kind of battle before there can be peace, which is in line with the so-called balance of terror.
The sword also evolved from the ancient "wangbiao". The function of wangbiao is to "determine the center of the world" and it is a symbol of "king"; so the sword is also called the king's weapon.

I can't pull it anymore~
In short, Chu Fei had the idea of ​​changing his weapon, and he was targeting the long sword. The current long sword design was perfect, even the streamlined shape of the guard was taken into consideration.

The handguard has a shuttle structure, and if you look closely it looks more like a fish. After thinking about it, Chu Fei thought of the famous ancient sword "Yuchang".

"How about I call this sword the Yuchang Sword?
How did the story of the Yuchang Sword come about? It seems that the Yuchang Sword is actually a dagger. "

After simulating and thinking in the virtual space for a long time, Chu Fei finally made up his mind - to change his weapons and become a swordsman in the future.

Mainly, in the simulation of virtual space, using a sword can give a 1.2% advantage over using a knife.

1.2% is very little, but considering Chu Fei’s current combat foundation, a gap of 1.2% is already unimaginable.

Chu Fei's current cosmic brain computing power has just been tested. The combined computing power of the cosmic brain itself and the Spring Thunder technique in the virtual machine has exceeded tens of millions.

1.2% is equivalent to an increase of 12 points in combat power.

The minimum score for a 10.0 awakener is 15. Considering that the actions of the practitioner themselves consume some computing power, the computing power that can actually be used for combat is about 12.

In other words, by changing a weapon, you can increase a basic unit of awakened combat power.

That’s because the sword is not very easy to use and is not convenient to use.

If you want to learn swordsmanship well, you need to work hard, which is much more difficult than knife skills.

In fact, the most important thing about swordsmanship is "strength", while the more important thing about swordsmanship is "skill".

As one's cultivation level increases, the requirement for strength becomes lower and lower - everyone has enough strength; on the contrary, more and more skills are required.

The so-called skills are not just dexterity, but more of a rule, an unpredictable rule, just like the "invincible" rule that Chu Fei is learning now.

When skills prevail, the requirements for weapons become more stringent. The long knife is probably ranked below the long sword and the long spear.

As for the whip, it can only be used as an auxiliary weapon. The whip has never been the main weapon.

After making the decision, Chu Fei sealed the design data of the war knife and took out the design data of the long sword for careful review. The design of the long sword just now was actually borrowed from the data of the war knife and was a primary version.

Now, Chu Fei needs to iterate and optimize the data of the long sword.

After repeated iterations and continuous testing in virtual space, the weight of the final version of the sword was reduced to 1.8 kilograms.

1.8 kg is still a bit heavy for a long sword. But it is made of copper, which is heavier than iron. One also needs to consider the strength of the sword, one's own combat strength, engraving formation (manifold), energy channel, etc. It has reached its limit. (Note ①)

After the virtual space was finalized, Chu Fei left the virtual space and immediately went to the weapons research laboratory to use machine tools to process an ordinary "steel sword".

Virtual space simulation calculations cannot be 100% consistent with reality. If you want to make the design of the long sword perfect, you still need real-life testing.

There is even a small wind tunnel in the Lan family’s laboratory. It is a super small wind tunnel that can only blow a model aircraft, but it is enough.

Test it in a wind tunnel, inspect it yourself, and then fine-tune it.

First, the sword body is ground directly. When it can no longer be ground, a new sword is processed and continuously tested.

After more than a day of testing, more than ten ordinary steel swords were scrapped, and finally a perfect design was iterated out.

The blade looks no different from the original design, and to the naked eye the difference appears to be no more than 1%, or even less.

But from the design drawings, you can see that the data, formulas, etc. have completely changed.

The design of this sword not only considers the surface fluid mechanics structure, but also takes into account the design of the "array". As the appearance is adjusted, the array design also needs to be adjusted.

It's like designing a fighter jet. If the appearance changes, the internal structure must also change. This is something that is easy to understand.

So, Chu Fei turned back to the laboratory and prepared to continue iterating the internal formation.

But in the secret room, Chu Fei met Wang Yujing who had been waiting for a long time.

The confident and radiant Wang Yujing made Chu Fei's eyes light up.

Seeing Chu Fei, Wang Yujing's eyes lit up and she smiled brightly, "Master, the goods from this auction have been sorted out and have been delivered to the Lan family.

Master, please sign if it's ok, and I will continue with the next process."

[Note ①: Data found on the Internet, the Qin Dynasty bronze sword, the Qin Dynasty bronze sword in the Ezhou Museum, is 90.3cm long, 3.1cm wide, and weighs 685 grams. The author also ordered a long sword that looks good when hanging but cannot be wielded, 1050 grams, not including the scabbard.]
