Chapter 290 Trial Pyramid

Perhaps it was related to the life and death of her father, herself and relatives, Song Lihua only took half an hour to prepare all the items, even far exceeding what Chu Fei needed.

Seeing a compartment full of supplies, Chu Fei even wondered if Song Lihua had just moved the warehouse here?
After choosing the required materials, Song Lihua led Chu Fei to the entrance of the underground world, and took the initiative to explain.

The underground world of Black Iron City also has a depth of one thousand meters, and there is also a dimensional space.

However, unlike the dimensional space in Feihu City, the dimensional space here seems to be openable at any time, but not unconditionally.

But what is the specific opening condition, Black Iron City has spent more than 120 years not figuring it out.

Sometimes it can be turned on automatically once every three or two months, and sometimes it doesn't turn on after two or three years.

The fastest record is: opened four times a year.

The slowest record is: opened once every five years.

Black Iron City has a history of more than 120 years and has been opened 107 times in total.This is much stronger than the dimensional space of Feihu City, which can only be opened once every two to three years.

And the seven opening opportunities that were obtained by accident can be opened at any time.But there are only two left, and I will use one more today.

After walking underground for a while, you will come to a spacious and bright "hall".

Song Lihua went straight to an "office", and then entered the password at a "security gate".During the process of entering the password, looking at Chu Fei staring at the password, he said softly:

"The password changes at any time, and there is a set of calculation formulas. Remembering the password is useless."

Chu Fei: ...

I knew it wouldn't be that simple.

As Song Lihua entered the password, a "water film mirror" suddenly appeared on the front "door", followed by a vortex.

Seeing this familiar scene, Chu Fei took a deep breath and walked forward slowly.

Will Black Iron City have other plans?Could this be a trap?
Of course Chu Fei considered these possibilities, but quickly put them aside.This is a dimensional space. With the current level of technology in the last days, it would be good to be able to open it. If you want to change it, don't even think about it.

Taking a step back, I have received several inheritances, and I have a considerable understanding of the dimension space. Even if there are any traps or dangers, it is enough to deal with them.

Knowledge makes me fearless!

But at this moment Zhang Liyu said, "Chu Fei, since you're here, I'm going to go back, and send the technology back first.

Maybe with these technologies, the industrial production of Flying Tiger City can be transformed, so it can also support Black Iron City. "

Chu Fei turned his head and glanced at Zhang Liyu, then nodded silently.Aren't you just running away, why did you say it so fresh and refined.

Even with Chu Fei's sensitivity, he noticed the sarcasm flashing from the corner of Song Lihua's eyes.

But the taunt was so fast that Chu Fei didn't even have time to distinguish whether the taunt was aimed at Zhang Liyu, himself, or Feihucheng.

But Chu Fei finally just nodded silently and plunged into the vortex.

The next moment, Chu Fei was stunned.

The world in front of him was changing, and then he saw a "peak" soaring into the sky.As for the width of the "mountain", it exceeded the limit of the field of vision.

As far as I can see, I can see that this "mountain" has five layers, and more of them have entered the clouds, and I can't see clearly at all.

The breadth, too, extends infinitely on both sides, until it exceeds the limit of the line of sight.

The air here is very pure, and Chu Fei's eyesight has been strengthened, and the visible distance can reach more than 200 kilometers.But even so, there is no end in sight on both sides.

In this dimensional space, there is only one building, the nine-story Trial Pyramid.In other words, the entire pyramid is this dimensional space.And entering this dimensional space is at the "first floor".

Such a vast and peculiar dimensional space, how much output does it have?
In the dimensional space of Flying Tiger City, there are such things as fairy fruits and fountains of life. Will there be similar treasures here?
Although this dimensional space is opened more frequently, the time to enter each time is about seven days, and the requirements for entering are not low. Compared with this huge dimensional space, the existing explorations are still just a drop in the bucket.

There is still [-]% of the area that has not been explored here, let alone the seventh floor and above have basically never been explored.

There must be treasures.

But then Chu Fei shook his head and laughed: "What are you thinking, this time it's not a treasure hunt, and there's not enough time, I have to try my best to get the CD on the ninth floor.

But can I really do it? "

Narrowing his eyes slightly, Chu Fei remembered Song Lihua's words and demeanor.Maybe she is not sure whether she can succeed, maybe at most she has only three or four hopes.

However, in the current situation, there is obviously no better way.

Song Tieyun, the city lord of Song, has disappeared from the waist down, and now he only dares to use the most common superpower potion even for the hanging bottle, and he is in a dying state.

Not to mention whether to save Heitiecheng, but just to save Song Tieyun, there are only three ways that can be thought of for the time being.

But for direct medical treatment, there are not enough resources, and it is too late to rebuild and transform. In the end, there is only a gamble-bet that I can get the CD!
Looking at the towering "mountain" in front of him, Chu Fei knew in his heart: Under normal circumstances, this kind of dimensional space would definitely not be able to enter casually by himself, and even if he could, it would not be so easy and alone.

"Perhaps, this is also an opportunity for myself."

Chu Fei immediately switched his mind, thinking of what he had just seen and told Song Lihua, the "trial" on the first three floors, he could completely ignore it, and he could just fly past it.

In fact, if you can fly, fly all the way up.

If you have the ability, you can fly all the way to the ninth floor.

While thinking, Chu Fei had fully spread his wings and flew up.

But just after takeoff, I felt disturbance and turbulence.In professional terms, there is turbulence.

There is a wind, but the direction of the wind is not fixed.

For this, Chu Fei had been prepared for a long time, and it was also explained in the materials prepared by Song Lihua.The solution is simple—strength works wonders.

But Chu Fei did not follow this "experience".

This is the "Trial Space". If you perform a miracle with great strength, you will slap the teacher's face with a big slap. It will be strange if you can get a good score in the end. If you don't have a good score, there will be no reward-you don't know anything except brute force, right? Orthodox research successor ah.

It's just brute force, the alien beast is much stronger than you.

So, of course the best way is - to solve the problem!
The first layer right now is just a basic test.

If it is flying, it is turbulence; if it is running wildly, it is a ground obstacle.

In short, as long as you move your feet, the test begins.And what kind of test will happen at random.

The college entrance examination has been hot for many years, guess how many test questions are there?

Chu Fei hovered in the air, carefully feeling the direction and law of the wind.Based on the basis of Chu Fei's mastery of the wind of perception, it only took three seconds to master the law.

It looks like turbulent flow, but it is actually a combination of simple equiangular spiral motion and the angle valley conjecture.It is also very simple to solve, as long as the law is calculated, you can avoid it directly.

It took only ten seconds for Chu Fei to complete the calculation, and then soared into the sky.

However, after flying at an altitude of 100 meters, a new turbulence was encountered.Chu Fei calculated again, this time it was a normal distribution.

There are still challenges to ascend another hundred meters, but they are all relatively simple and in an ideal state.

After flying to an altitude of one kilometer, Chu Fei encountered a new problem after reaching the height of the second floor.This time it's a whirlwind with a twist.

This twisting whirlwind made it difficult for Chu Fei to maintain the balance of his flight.

Feeling the whirlwind, Chu Fei was thoughtful: If the first layer is the wind in an ideal state, then it is a bit close to the actual situation now, although only a little bit closer.

Therefore, it can be inferred that the top must be a completely realistic wind direction, and it is very likely to be a howling wind.

The actual wind direction is actually a chaotic model, and there is no precise answer, so weather forecasts are all probabilities. Even if the probability is 99.99%, it still cannot reach 100%.

However, the test on the second level is relatively simple, and it only took Chu Fei 20 seconds to analyze it: Compared with the test on the first level, a variable was added, which is rigid transformation.

After flying another 100 meters on the second floor, a new challenge, or "examination question" appeared.Chu Fei quickly analyzed it.

The second layer is very simple, and the third layer is also very simple, at least for Chu Fei.

But starting from the fourth layer, ternary equations began to appear, and 'modulo arithmetic' began to appear on the fourth layer; the fifth layer was a set, and the sixth layer was a matrix.

Chu Fei flew to the height of the seventh floor in one breath, and it took only more than 20 minutes.

On the seventh floor, Chu Fei encountered a problem.Feeling the gust of wind around him, he sighed again, "I thought that the real problem could be solved only on the ninth floor, but this is the seventh floor."

The actual wind direction has never been standard, and it is somewhat turbulent.

The surge formula has no solution, and can only be approximated—just like the weather forecast, although it can be infinitely close, the approximate value is not a "correct solution" after all!
Feeling the chaotic and disorderly wind, Chu Fei couldn't hold on after flying up for more than ten minutes, and had to fall to the sixth floor to take a rest.

If you can't analyze the turbulent flow in it and rely entirely on brute force, the seventh floor won't be able to gain a foothold at all.In fact, if you rely on brute force, even the fourth floor is difficult, and the fifth floor is unnecessary.

Relying on brute force can solve some things, but if you want to sprint to a higher level, you need knowledge in addition to brute force!
Faintly, Chu Fei has a certain understanding of the dimensional space of this trial.Although Song Lihua explained some things before, others' explanations were never as profound as her own.

However, if we want to analyze the practical problems of the seventh floor, relying on the current cosmic brain and computing power, we can only use tricks.

If there is no trick, the calculation is completely based on the relevant data of fluid mechanics, and supercomputer assistance is required.

And the tricky way is: disassemble the infinite calculation of differential into a finite calculation of segments.In theory, as long as the dismantling is fine enough, the final result will be infinitely close to reality.

Relying on this method, Chu Fei tried twice, and when the calculation accuracy increased to the percentile, he finally officially stepped on the height of the seventh floor.

This is considered a record in the Black Iron City.But Chu Fei didn't have the slightest joy, because there was a greater goal - the ninth floor!

Relying on this method of splitting, Chu Fei made it all the way to the last track on the seventh floor, and finally couldn't break through.

The method of splitting is not easy to use; and if you want to perform a complete calculation, the computing power of the universe brain is a bit insufficient, and it gets stuck when the calculation reaches about 30%.

After looking at the difficulty of the rest of the calculation, Chu Fei didn't want to use the wisdom dew at all.Although the remaining calculation process is 70%, the difficulty is 99%!

How to do?
After thinking for a long time, Chu Fei got nothing, and couldn't help muttering, "Not even a reminder."

[Ding... the first reminder: the greatest thing about human beings is that we can create tools to solve difficulties.Ordinary humans cannot fly, but they can soar into the blue sky in an airplane.This is the power of technology, and technology itself is the crystallization of knowledge and wisdom.

Remaining reminders: 2 times. 】

There is really a reminder, or voice control technology?
However, creating tools?

Chu Fei was thoughtful: Many mathematical formulas, such as Bernoulli's formula, are tools created by researchers, and these formulas do not exist in nature.

Could it be that, in order to break through the seventh floor, do you need to create a formula?

But it's not right, this test is aimed at teenagers under the age of eighteen, so it's impossible to be so exaggerated.

So, that should be another tool: a weapon, an actual technological artifact, or a solution.

Suddenly, Chu Fei thought of the magic weapon (nano-liquid gold) he had absorbed, but just as he was about to drive the nano-liquid gold, he suddenly received a warning: Please use your own ability to solve the problem.

Use your own abilities?Do you want to turn yourself into a weapon?
Hey, wait, it seems to be really possible.

Suddenly, Chu Fei narrowed his eyes, and his figure began to spin.

It should be said that although there are many ways of flying a dragonfly, it really does not include rotation-the kind of rotation centered on its own center of gravity, like a spinning top.

But Chu Fei is not a dragonfly, but an awakened one!Awakened with wisdom and technology!
After trying to change the flight mode many times, Chu Fei has mastered the way of his own rotation - it is enough that the force on the wings on both sides deviates.

After a few attempts, Chu Fei could move forward in an arc.Inadvertently learned a way to fly.

Using this rotating flying method, Chu Fei drilled directly into the eighth floor like a drill bit.

Then Chu Fei seemed to open his mind, not only analyzing the external environment, but also creating his own environment.

Faintly, Chu Fei grasped one element: creation!
When the mind is opened, the problem is relatively simple.The wind pressure on the eighth floor is a bit high, not only does it not have the so-called thin atmosphere at high altitudes, but it feels sticky, and the air seems to be turning into substance.

Chu Fei optimized the rotation speed according to the actual situation, etc. After half an hour of trying, it ended in failure... I'm a little tired, let's take a rest first, and think about it before talking.

Thinking of this, Chu Fei fell to the seventh floor.

The stepped pyramid on the seventh floor is full of sculptures, all kinds of sculptures.

In fact, if you break through step by step and go up layer by layer, you will also be tested on your learning ability-how to break through to the next level is written on these sculptures.

Among them are large reliefs engraved with mathematical formulas and data structures.

Looking at the mathematical formulas on the scene, Chu Fei's eyes lit up.

The mathematical formulas on the seventh floor are already very delicate.

"Maybe Black Iron City's technology is obtained from this pyramid. But they have never come up to the seventh floor, which is cheap for themselves.

It's just... the area is too big. "

Although the area of ​​the seventh floor is already small, it is still very large. There are too many sculptures, densely packed like a forest.

Faintly, Chu Fei had an indescribable regret: he was not allowed to enter Baoshan!
Thinking like this, he was still walking slowly on the seventh floor, and suddenly Chu Fei saw a unique model - negative pressure, or vacuum.

Through the unique flight mode, create a certain negative pressure around the body, so that the density of the "whole" formed by yourself and the surrounding is lower than the density of air, and you can float!
Chu Fei's eyes lit up and he looked carefully.This unique flight mode is actually born out of the flight mode of bees.

The flight of bees relies on creating vortices to provide lift, but we know that tornadoes are also vortexes, but the center of the tornado is negative pressure.

In fact, a considerable part of the lift of the aircraft comes from the negative pressure above the wings.

Therefore, this flight mode is to embed the mechanical flight mode into the biological flight mode, creating a unique and scientific flying method for human beings!

"It turns out that this is creation!
It's just that this model seems a bit complicated. If ordinary awakened people come to learn this, it will take half a month just to read these formulas and understand the logical structure.

If you want to build a model in the cosmic brain and apply it to the actual flight, it will take more than half a year? !

It's time, Wisdom Dew, speed me up! "
