Chapter 77 The Voice of Heaven
After observing for a while, Chu Fei found the "General Outline of the Wind of Perception".

First turn to the catalog page, the catalog is divided into five parts.

First, introduce the life base of spells, and what is 'Wind of Perception';
Secondly, it is the scientific theory and technology needed by the wind of perception;
Thirdly, it is the means of detection and data collection;
Finally, establish a mental model to restore the data into a "picture" that the brain can understand.

Finally, when the wind of perception is familiar enough and the personal practice is strong enough, the data can be read directly, and there is no need to "restore the screen".

The last point is easy to understand. As we all know, servers use character interfaces, and home computers only pay attention to graphical interfaces.

After reading the catalog, Chu Fei opened the prologue.

The prologue mainly introduces the life basis of spells.

Life itself is a miracle, a spell.

Self-will, observer effect, thought drives body...

All of this can be explained not only by scientific thinking, but also by magical thinking.

And the spells and practices of some fantasy civilizations in the universe are only developed on this basis.

Since other civilizations can do it, we as a scientific civilization can also do it, and do it better.

After all, there is an essential difference between fantasy civilization and scientific civilization.

The development model of fantasy civilization is similar to the situation of the ancient civilization of the earth - summarizing experience in the long production, and then solidifying the experience into technology, the time span is long, the efficiency is low, the divergence is large, there is no unified standard, the faction is divided, and so on.

To sum it up: start with the phenomenon.

On the other hand, scientific civilization directly deduces the basis from scientific theories and starts directly from the essence.

Therefore, fantasy civilization pursues ascension, becoming a god, and immortality, and scientific civilization directly expresses that I want to become a pure data life.

After reading the preface, Chu Fei was thoughtful.

Tap a virtual box above the book, and then the whole book is transformed into a data stream, which is quickly written into Chu Fei's consciousness.

This kind of reading is very efficient, but it also puts a lot of pressure on the brain and spirit.

In just one minute, the contents of the entire book had been completely written into Chu Fei's mind.

A few minutes later, Chu Fei slowly opened his eyes.

"I see!"

Afterwards, Chu Fei turned his head and walked towards a virtual box, and clicked on 'simulation experience'.

Scientific practice must have scientific characteristics.

Just as a person knows how warm or cold the drinking water is, it is better to experience magic spells to gain a deeper understanding.Virtual technology can meet this requirement.

The next moment, Chu Fei appeared in front of a huge rock.

Lines of information emerge from the front, introducing the current "simulation situation" - through active sound, echo, sound refraction, diffraction, etc., using calculation methods to obtain "three-dimensional points" one by one.

When a large amount of [-]D point data is obtained, an abstract three-dimensional picture is restored by modeling.

Then use rendering methods to repair the image, and finally get a blurred picture.

Compared with the mountain and rock in front of me, this picture has a similar general frame, but there are no details at all.

But compared with the eyes, the wind of perception can "see" the back of the rocks!
The line of sight cannot be turned, but the sound can.

Then start the second simulation.

Chu Fei's eyes went dark, and he couldn't see the picture at all.

This time, Chu Fei only took the initiative to make a sound, and the computer was responsible for the calculations, restoring a three-dimensional image.

After the calculation is completed, the vision is restored.

Chu Fei proofread the results. The general outline is fine, but the details are still blurred.

Then start a new simulation.

This time, "line" scanning and "surface" scanning simulation are adopted.

Compared with point scanning, line and area scanning methods are faster and require more calculations, but the image is still blurry.

At the same time, in order to better capture the sound, the hearing gene must be turned on - this is the ability of the awakened.

Then the combination of point, line and surface, the computer runs more than a dozen calculation threads at the same time, and the shape of the mountain and rock is calculated in just a moment, and it is relatively clear.

When Chu Fei looked carefully, clarity was also relative. The wind of perception relies on sound waves, which are not as delicate as light waves, and the highest resolution is only 10 centimeters.

The simulation continues.This time ultrasound was used.

Ultrasound has higher efficiency, shorter wavelength, and more delicate scanning results, with a scanning accuracy of 3 cm.

The hearing gene continues to be turned on, strengthened, and begins to strengthen the cells of the whole body, so that the skin has the ability to perceive sound.

Then a variety of sound waves are combined, and the points, lines and surfaces are calculated at the same time, and the scanning accuracy finally reaches 1 cm.

But from beginning to end, the world "seen" by the wind of perception is black and white.

The simulation continues.

This time, Chu Fei appeared underwater.

The wind of perception can only be used in the air?

nonexistent.

The essence of the wind of perception is sound waves and vibrations, so it can be used underwater as well.

But the underwater effect is much worse.

The speed of sound in water is about 4.4 times the speed of sound in air, which means that the wavelength increases and the perception results are rougher.

But the speed of sound in water increases, and the efficiency of the perceived wind increases abruptly.

The next simulation, is perspective.

Scientists use infrasound waves to detect the internal structure of the earth, and ultrasonic flaw detection is also used in medical or industrial applications.

But this also requires more powerful computing power.

During the simulation, Chu Fei's hearing gene was turned on all over his body, and his skin and bones had the ability to perceive sound or vibration.

Using sound waves, Chu Fei "seeed" the inside of rocks and trees.

But the perspective ability of sound waves is completely opposite to visual experience.

Because, the harder the material, the better the sound transmission.Therefore, under the perception of sound waves, steel is "transparent", but air is invisible.

After collecting the data, input the sound velocity parameters of different substances for rendering, and finally get the inverting result, which can restore a normal world.

But the world under the wind of perception is still black and white.

Until the next simulation: color vision, which borrows from music to edit data.

This time, sounds of different frequencies, different perception methods, different data collection methods, different calculation methods, etc. began to be calculated in parallel.

A "colorful" world emerged.

But the "color" under the wind of perception is completely different from the color of vision.

The "color" here refers to the hardness and flexibility of the material.

According to a series of reference data such as the speed of sound of different substances, the refraction and reflection of sound, sound absorption, the interaction of different frequencies of sound and substances, etc., the physical situation can be restored.

The "color" here is the color of sound, which can be understood as music.

The simulation gradually ends.Finally, Chu Fei closed his eyes, feeling a different kind of "vision":
The wind gently blows through the treetops, the birds chirp, the springs jingle, the fist-sized fluffy animals with big tails quickly climb over the tree trunks, the fallen leaves gently fall into the spring water, and the fish jump out On the surface of the water, there are long, long animals winding forward underground...

Chu Fei stepped on the fallen leaves, wandering in the world of music.

This is... the sound of nature!
