Chu Fei stood on the podium, his eyes slowly closed, chasing the enlightenment in his heart.

The spell model of ‘Sensory Wind’ was quickly formed in my mind.

This is a real spell, not the "small spell" behind the textbook before.

At some point, Chu Fei waved his hand gently, and a breeze formed around him, which slowly spread.

The wind was completely controlled by Chu Fei and no longer flowed at will; it was like an extension of the body.

This is a very wonderful feeling. This extension has some tactile, part hearing, and part vision characteristics, but it is also very hazy.

The world reflected by the wind of perception is an abstract grayish-white area with fluctuations like reflections on the water.

Under Chu Fei's control, the breeze was gentle, continuous, spreading slowly. It blew across the podium and Chen Wenxin next to it.

The breeze blows through the tables and chairs, and you can feel the blurred outlines of the tables and chairs.

When blowing through Chen Wenxin, you can feel a breeze around Chen Wenxin, blocking Chu Fei's "peeping".

Continue to extend, and finally expand to about 5 meters, so that the breeze will not be controlled and reach its limit.

"My perception radius is about 5 meters." Chu Fei realized in his heart.

The breeze spread, eventually covering the surrounding area of ​​ten meters, with the highest point extending to the ceiling.

Chu Fei wanted to feel it well, but suddenly felt dizzy.

"No, my mental power is exhausted again! It is indeed a real spell, and it consumes a lot."

Chu Fei withdrew from his senses and his figure was a little staggering.

Chen Wenxin finally spoke, his words full of surprise, "You have actually realized the wind of perception yourself."

Chu Fei laughed twice and said proudly: "The main reason is the teacher's courseware details.

In fact, it is not that difficult, it is the extension of the mechanical waves of the human body, which resonate with the surrounding air."

Chen Wenxin nodded, "In fact, it is just a sonar, the core is vibration. The transmission of vibration in the air is sound waves."

"Is the sound wave? Can ultrasonic waves be used?"

"Of course. You can only say that you have just learned to perceive the wind, and it is too early to use it flexibly. After you have fully mastered the perceived wind, it can replace most of the functions of the eyes and ears."

Chu Fei thought about it and asked, "But my feeling is very vague. I can only 'see' the hazy lines and grayish-white colors. Such ability can only be used as an auxiliary, right?"

"You just used only one frequency, and you can try to match multiple frequency.

The most commonly used ones are three frequency combinations, one main one and two auxiliary ones.

You can practice more. If you don’t understand, ask me.

Let’s go back to the seat and let you see the courseware in 10 minutes.”

Chu Fei walked back to his position step by step, and the friends around him showed shocked eyes.

After sitting down, Chu Fei did not look through the courseware, but entered the thinking and compared the differences between the wind of perception and the sixth sense.

The sixth sense is the extension of mental power and the foundation;

The range of the sixth sense is very narrow. In natural state, it can only expand to one foot outside the body; if it continues to expand, the consumption will be extremely high;

The sixth sense has complete perspective ability, 360° without dead corners, and you can see what you cannot see in your eyes, such as "seeing" the movement of dust, seeing infrared radiation from the body, seeing the situation inside the body, seeing the colorful world, etc.

The wind of perception is a spell and a tool;

The range of perceived wind is very wide, with a radius of up to 5 meters. If it exceeds 5 meters, it will lose control and cannot continue to expand;

The perceived wind can only observe the earthly space and hemispherical shape; for the time being, only a fuzzy and abstract gray-white world can be observed;

Also, the perceived wind has a speed limit, and the upper limit of speed is the speed of sound.

However, the perceived wind consumes very little. If the range is shrinking and the frequency is reduced, the feeling can be turned on 24 hours a day and used as a warning.

For the time being, the perceptual wind is more practical; it is better to match it with eyes and ears.

Moreover, the line of sight cannot turn, but the wind of perception can be.

Chu Fei knew it in his mind.

Chen Wenxin started his lecture. During the explanation, he frequently mentioned Chu Fei and used Chu Fei as a model.

With Chu Fei as a reference, some concepts are easy to explain clearly.

Chu Fei also benefited a lot; Chen Wenxin also pointed out many problems with Chu Fei during his explanation.

Chu Fei listened seriously.

After Chen Wenxin finished speaking, Chu Fei adjusted the magic model.

Chu Fei chose one main frequency and two auxiliary frequencies. The three frequencies cooperated with each other and covered the surrounding ten meters.

"Adjust the temperature parameters, fine-tune the frequency, and try to increase the second sound wave..."

Chu Fei adjusts one by one, experiments one by one, and constantly explores.

Gradually, the "view" of the wind of perception began to become clear.

By perceiving the wind, you can feel the "data" such as temperature, density, size, etc.; you can "see" the "view angle" in five directions in front, back, left and right.

This is a strange world, completely different from the colorful world seen by the eyes.

There are no colors in this world, only lines, outlines, and data.

Through the big data model of spells, these data can be restored to a black, white and gray world.

Due to air disturbance, the "view" of the perceived wind fluctuates like water marks.

Chu Fei continued to adjust and gradually discovered more advantages of the wind of perception.

First of all, optical invisibility and illusion methods are useless in the face of the wind of perception.

Secondly, the perceived wind can turn, you can "see" behind the table and chairs, and you can drill into the gap; the perceived wind does not require light.

"This is the real magic, the real superpower." Chu Fei sighed in his heart.

Suddenly, Chu Fei discovered that a dewdrop as big as sesame seeds had been condensed on the fourth leaf that had just formed in the wisdom tree.

Chu Fei raised his eyebrows: This speed is a bit scary!

What's the reason?

Since last night, the dewdrop condensation rate has suddenly increased by 50%, and now it has increased a lot, and it feels doubled - it doubled on the basis of 150%!

This is not normal!

Good things come inexplicably and make people confused.

However, I can only explore and analyze this matter by myself.

Chu Fei opened his eyes and did not completely close the wind of perception.

The wind of perception runs in a low-frequency state, consumes very little mental power, which can be used as a supplement to vision and hearing, and the world is unprecedentedly clear.

Then, Chu Fei looked at the classmates, especially Yang Xiaozhu.

"Ahhhhh..." Yang Xiaozhu's 'Come to the Sky'. A light curtain flashed on the fully intelligent desk to correct Yang Xiaozhu's shortcomings.

Suddenly, when he found that Chu Fei was ecstatic, Yang Xiaozhu turned pretty and glared at Chu Fei fiercely, like an angry little tiger, with a fierce look: "What are you looking at!"

"Learn from the class monitor."

Yang Xiaozhu "furious" 'roaring': "Everyone is shouting, but you don't."

A head immediately poked out from behind and shouted, "Chu Fei, the squad leader Xiaozhu is asking you to scream."

"Haha..." The surroundings laughed wildly.

Yang Xiaozhu picked up the textbook and slapped it hard on Zhang Weige's head.

With the sound of laughter around, Chu Fei heard a grinding voice. He suddenly turned his head and got into Huang Haifeng.

There was still a faint smile on Chu Fei's face.
Chapter completed!
