Chapter 114 The Wind of Perception Begins

"The road is long and long, and I will search up and down!"

At dusk, Chu Fei stood on the edge of the cliff in front of the dormitory, feeling the strong mountain breeze.

The street lights have not yet been lit, but the shadow of the high wall has already enveloped the earth.

Standing on the edge of the cliff is like standing on the edge of an abyss, with chaos ahead, just like the choice faced by a semi-awakened person.

Suddenly, Chu Fei's ears twitched slightly, then he slowly turned his head and saw a figure jumping down from the cliff on the other side.

Chu Fei watched silently, feeling nothing at all. This is the third one I've seen this month.

Shuguang Academy has recently increased its "cultivation intensity" a lot for unknown reasons.

Maybe for the dimensional space?

The howling mountain wind brought a few withered yellow leaves and fell on Chu Fei's palm.

Looking at the yellow leaves in his hands, and then at the mottled hillside, Chu Fei couldn't help but sigh: "I didn't realize it was already autumn, and it has been more than a month since I started this retreat.

Try the results of your recent practice.

Let’s test the wind of perception first. "

While thinking, Chu Fei slowly closed his eyes, and the model of the wind of perception began to run, borrowing the power of the wind - mainly the sound waves in the wind, to explore the surrounding terrain.

In the howling mountain wind, each three-dimensional point was quickly refreshed. With his powerful thinking ability, Chu Fei can create thousands of three-dimensional points in one second.

Because the terrain to be explored is static, each three-dimensional point only requires three data and does not require dynamic data such as vectors, so the calculation is very fast.

After each three-dimensional point was determined, it was mapped in Chu Fei's mind, and a topographic map was formed in his mind in the form of a dot matrix.

One or two three-dimensional points, nothing can be seen;

Only three to five three-dimensional points can simply describe the general shape of an object;

Hundreds of three-dimensional points can more accurately outline the shape of an object;

But when thousands or tens of thousands of three-dimensional points are accumulated, a magnificent picture can be constructed.

But so much data puts a lot of pressure on calculations.

At this moment, there are two complete "advanced computing units" in Chu Fei's consciousness space, which are performing crazy calculations.

An advanced computing unit includes four primary computing units and 16 unit cells.

Now Chu Fei has two computing units and has also learned virtual thread technology.

Therefore, Chu Fei is now a dual-core and four-thread master~~~

An advanced computing unit is responsible for driving the wind mode of perception and detecting the surroundings; an advanced computing unit is responsible for recording and restoring.

As the wind of perception continued to spread, the picture in Chu Fei's mind slowly expanded.

No, it shouldn't be called a picture scroll, because this "picture" is three-dimensional.

Perhaps, it should be called ‘image’.

It's just that this image is a bit abstract, made entirely of dots, and has only one "color" for the time being.

In the world of sound, perhaps it cannot be called color, but should be called ‘sound quality’.

The word color can actually be 'translated' into "light quality".

Regardless of sound quality or light quality, the essence is wave, one is sound wave and the other is light wave.

But by translating it this way, you can have a deeper understanding of what "sound quality" is.

In short, in the world of data, sound quality can indeed be seen as the color of the sound.

Chu Fei devoted himself wholeheartedly, and the wind of perception continued to extend. Finally, when the perception range expanded to a radius of 100 meters and a diameter of 200 meters, the computing power reached its limit.

At this time, Chu Fei's consciousness space has recorded 80,000 three-dimensional points, which outline the terrain around the cliff in a dot matrix.

If we want to continue spreading outward, our computing power is no longer sufficient.

In this situation of completely perceiving the surroundings, one hundred meters is the limit.

Then, Chu Fei began to "paint".

Coloring, to put it simply, is to bring different sound waves into the existing database, compare them, and then start adjusting the "sound quality".

The sound quality of trees, the sound quality of stone, the sound quality of earth...

Gradually, "color" appears in the image, and through calculation and rendering, three colors appear.

The depth of the stone, the looseness of the soil, the illusion of the trees;

As for more detailed flowers and plants, of course they are not within the perception range of the wind of perception.

The winds of perception are primarily sound waves.

Chu Fei temporarily borrowed sound waves from nature. Sound waves have a wavelength of more than one foot and cannot scan objects within 30 centimeters.

Coupled with the dot matrix image, it can only show the approximate collapse of the object.

This is the shortcoming of sound, because the wavelength of sound waves far exceeds that of light waves, and the winds of perception can never reach the delicacy of light.

But the wind of perception does not need light!

It's still available in the dark. Even the night is quieter, with less interference, and the effect of the wind of perception is better.

After Chu Fei carefully felt the all-round wind of perception, he began to switch modes.

This time, instead of perceiving an almost spherical space, the perception is spread out in a fan shape to form a trumpet-shaped "scanning" range in front of the body.

When the angle is 30 degrees, the sensing range is the farthest and clearest, reaching a distance of 200 meters.

If the range is less than 30 degrees, it will be difficult to scan the surrounding area clearly due to missing data.

At this time, the scanning speed is 1 degree per second - the degree of angle. 360 degrees a week.

In other words, Chu Fei can act like a humanoid sonar and complete an all-terrain scan in 6 minutes.

After recording relevant data, Chu Fei switched modes again.

This time, it is a long-range lock-just like hunting in the wild.

Directly use sound to lock the distant target.

To lock the distant target, it is generally a dynamic target. Each three-dimensional point requires four data, including vectors. To lock the approximate outline of an object, at least three points are required.

This time, the record reached a distance of 340 meters. Here, it has reached the limit. Because the speed of sound is 340 meters per second!

This is also a limit of sound.

It is not impossible to go farther, but because the sound propagation time is too long, the meaning of locking is not great. Moreover, the distance is too far, the degree of interference to the sound increases, and the calculation accuracy itself will also be reduced.

Chu Fei also wants to continue to test the farthest perception range-using infrasound;

He also wants to test the closest and most accurate perception-using ultrasound, the wavelength of ultrasound is less than 2 cm!

But at this moment, the dynamic target locked by Chu Fei spoke. "Chu Fei, are you having fun?"

It turned out to be Huang Gang's voice!

It was dark at the foot of the mountain, and Chu Fei could not see clearly. But the perception wind expanded a little, and he "saw" the general situation. Huang Gang was dragging something behind him with a rope.

Got it, dragging the body.

A bit of a downer.

But Chu Fei still asked curiously, "Captain Huang, can you feel the lock? No, I'm using natural sound waves, not active detection."

"No, there's still some light from the sky there, I can see clearly."

"..."

That's right, Huang Gang is in the dark and I'm in the light.

I've become stupid from practicing.

I need to reflect.
