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 wisdom tree seed in the consciousness space.

However, at this time, the wisdom tree seed began to be lazy again and slowly rotated.

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

Then Chu Fei stared at the copper skin in front of him again: this copper skin with a width of 2 cm, a length of 30 cm, and a thickness of 2 microns.

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

Such a thin copper skin feels like it can be blown apart by blowing hard. But such a copper skin is now extremely hard.

Chu Fei picked it up and waved it, and the hardness was like 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 soft. 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.

Swinging the copper skin and chopping it off, there was a sound like cutting wood. The seemingly fragile copper skin cut into the broken sword like a steel knife, and the cutting edge was 2 cm deep.

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

This was because Chu Fei did not use force.

Pull it out, use force...

There was only a clang, and the sword was cut off directly.

Chu Fei looked at the cut of Guanghua, and was actually somewhat shocked.

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

The hardness of red copper was ordinary metal copper before, and the copper skin was even more fragile and could be broken by blowing.

As a result, it was just a simple manifold "drawn" on the copper skin, and it changed.

"So that's how it is. This is the correct smelting posture for magic weapons."

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

In fantasy practice, special true essence, introduction of thunder, and even sacrifice are often required, which is probably looking for "ink";

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

Just now in the process of "drawing", it is necessary to follow the inherent energy channel and structure in the copper skin, and even fine-tune it, and 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, that is, a manifold.

In addition, there are many details, which require Chu Fei to explore bit by bit.

But at least, the preliminary experiment was successful.

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

Recall everything just now with your eyes closed.

The most difficult part of this is seal carving. You need to feel the properties of the material, maintain the manifold, and keep the material properties and manifold compatible. At the same time, you must keep the energy from being released and not reduce the dimension.

After thinking for a long time, Chu Fei took out 10 grams of red copper again and repeated the action just now. But this time Chu Fei only prepared 0.1 mm copper skin, not 2 microns.

Finally, a copper sheet of 2×60 cm in length and width was made.

Such a copper sheet is a bit narrow, and Chu Fei needs to change the way of engraving.

After thinking about it, Chu Fei tried to use a curse - how about I directly use the curse to project the "array" onto the copper sheet?

After trying it, he found that it was a bit difficult for the curse to attack the metal copper - no matter how soft the copper is, it is still metal. Now Chu Fei's curse strength is limited, and it can only explode.

"I can only do engraving. It seems that I have to make special tools. Then come on."

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

It is not difficult to make special tools. It is to make a "needle" that can conduct life energy - it can be understood as a kind of engraving pen.

It is still made of red copper and it was made quickly. Even on the "engraving pen", diodes, triodes, capacitors and other structures were added to increase stability, amplification, aggregation and other effects.

In just one hour, Chu Fei made a seal-carving pen with an accuracy of 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 sharp eyes could distinguish 0.005 mm or even finer resolution.

This time, Chu Fei took three hours to carve the same manifold.

When the last stroke was finished, an ultra-thin machete blade appeared in front of Chu Fei, but it was just red copper.

As Chu Fei injected energy, the machete was suspended in the air, and a faint light flowed on the surface. Because the thickness increased, it was obvious that the injected energy increased, and the circulation was faster.

Holding the blade, cutting towards the scrapped broken knife, cutting iron like mud!

The results of the two experiments were very good. This shows that the first refining of the magic weapon was successful.

But this success can only be regarded as a "laboratory result". If you want to truly transform it into a real industrial product, there is still a long way to go.

For example, a war knife must be at least 1.2 meters long, 1 cm thick, and 4 or 5 cm wide. Even if the material strength is improved, the thickness can be reduced to 0.8 cm. It cannot be lower, otherwise it will affect the feel.

Even if the thickness is 0.8 cm, each layer of copper is calculated as 0.01 mm, there are 800 layers!

Of course, the specific thickness of each layer needs to be studied carefully.

If the thickness is too thin, the passing energy is too low, the strength is affected, and the processing difficulty increases;

But if the thickness is too large, resulting in too few superimposed layers, it will also affect the final quality of the magic weapon.

In fantasy practice, a magic weapon often has only one layer of formation engraved on it. At most, the blade has 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 starts with 300 to 500 layers.

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

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

This requires entering the virtual space for iteration.

After carefully studying the current experimental product, Chu Fei prepared more than a dozen copper skins of different thicknesses and engraved multiple manifolds. He studied for more than two days and collected enough information.

Two days later, Chu Fei put away all his items, exited the research room, 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.

Each layer is designed to be 0.012 mm thick, with a straight blade shape. The thickest part of the blade is 9 mm, 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 is much lighter than expected, mainly because the strength of the magic weapon is beyond imagination.

But in addition to the straight knife, Chu Fei also designed a long sword, with similar data, but the length is only one meter, and because the blade is sharpened on both sides, the actual weight is only 2 kg.

The reason why a long sword was designed is because... it's cool.

Although there are many people who complain about long swords, it's really cool to use a sword.

Well, this is only a secondary reason. There is another more important reason-fluid mechanics.

Compared with a long sword, the shape of a sword is more suitable for fluid mechanics.

As Chu Fei's practice increases and the combat speed increases, the turbulence driven by the blade cannot be ignored. Especially when the blade speed exceeds the speed of sound, the shock wave caused has begun to affect the stability of the blade.

But the sword body can avoid this result.

This turbulence can be simulated: the palm quickly passes through the water.

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

But the problem is that the sword is really not easy to learn.

A month of sticks and a year of swords, a lifetime of guns, and a sword is hidden with the sword; these are the experiences summed up by the older generation over thousands of years.

If you want to practice the long sword well, you have to hold it when you sleep. This is no longer a weapon, but a companion.

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

The sword is sharpened by grinding, ten years of sharpening a sword, taking off the sword and crossing it in front of the knee, relying on the sky for thousands of miles, you need a long sword, holding a sword and being wild, a sword frosts fourteen states...

In fact, the sword culture has 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 truth of Yin and Yang Tai Chi, and the shape of the sword is completely matched with the word "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 Yanhuang civilization matured, a kind of thought that is born with.

The sword, being upright, implies the meaning of reaching the sky; the blade is sharpened on both sides, hurting others and oneself, there is a kind of battle before there is peace, which is in line with the so-called balance of terror;

The sword also evolved from the ancient "watching watch", the function of which 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 talk about it anymore~

In short, Chu Fei now has the idea of ​​changing weapons, and the long sword is what he is eyeing. The current long sword design is even more flawless, even the streamlined shape of the guard is taken into consideration.

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

"How about my sword be called Yuchang Sword?

By the way, where does the allusion of Yuchang Sword come from? It seems that Yuchang Sword is actually a dagger."

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

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

1.2% is very little, but considering Chu Fei's current combat foundation, the difference of 1.2% is unimaginable.

Chu Fei's current cosmic brain computing power has just been tested. The cosmic brain itself plus the spring thunder technique in the virtual machine have exceeded 10 million.

1.2% is equivalent to an increase of 120,000 points in combat power.

The minimum standard for 10.0 awakeners is 150,000 points. Considering that the actions of the practitioners themselves need to consume some computing power, the computing power that can really be used for combat is about 120,000.

In other words, changing a weapon can increase a basic awakener's combat power unit.

This is because the sword is not easy to use and not convenient.

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

Speaking of which, the most important thing about knife skills is "strength"; and the more important thing about sword skills is "skills".

As the cultivation level increases, the requirements for strength are getting lower and lower-everyone has enough strength; on the contrary, more and more skills are needed.

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 sword is roughly ranked below the long sword and the long spear.

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

After making the decision, Chu Fei sealed the design data of the war sword 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 sword and belonged to the primary version.

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

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

1.8 kilograms is still a bit heavy for a long sword. But the material is copper after all, which is heavier than iron. It is also necessary to consider the strength of the sword body, the strength of one's own combat, the engraving formation (manifold), the energy channel, etc., which has reached the 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 a machine tool 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 to test it in reality.

There is even a small wind tunnel in the Lan family's research room, which can only blow a model machine, but it is enough.

Use the wind tunnel test, then personally test it, and then fine-tune it.

First, grind the sword body directly, and when it can't be ground anymore, process a new long sword and test it continuously.

This test took more than a day, and more than ten ordinary steel swords were scrapped before and after, and finally iterated a perfect design.

The sword body looks no different from the original design. The difference does not exceed 1% or even lower to the naked eye.

But on the design drawing, you can see that the data, formulas, etc. have completely changed.

The design of this sword is not only about the surface fluid mechanics structure, but also about the design of the "array". As the appearance is adjusted, the design of the array must also be adjusted.

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

So, Chu Fei returned to the laboratory and prepared to continue iterating the internal array, etc.

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 also lit up and showed a bright smile, "Master, the goods received from this auction have been sorted out, and the transaction with the Lan family has been completed.

Master, please sign if there is any problem, and I will continue with the following procedures."

[Note ①: Data found on the Internet, Qin Dynasty bronze sword, Qin Dynasty bronze sword in the Ezhou Museum, full length and width 3.1cm, weight 685 grams. The author also ordered a long sword for himself, which looks good when hanging but cannot be danced, 1050 grams, not including the scabbard. ]
