"Okay, that's the end of the problem of reverse Xuangong."

Mu Feng'er let go of her hand and motioned for the students to return to their seats.

She walked to the podium, raised her hand and took back the seven Elemental Xuangong, and said, "Everyone has just read the Huangpin Elemental Xuangong, and after class, find time to transfer to the cultivation by yourself." ”

"I'll tell you about the future course arrangement, the morning is a theoretical class, the course content includes Xuangong cultivation, elemental condensation, and Dongxuan historical events, etc., I will depend on the situation arrangement."

"The format of the course is similar to today, mainly lectures and discussions, and in the future, problems in cultivation can be raised in class, and everyone brainstorms and discusses and solves them together."

"In the afternoon, there will be mainly practical combat courses, including the learning of basic mystical skills, the preliminary condensation of basic magic skills, and simulated battles."

"Teacher Mu, with our current cultivation, can we cast magic skills?"

Hearing this, a student raised his hand excitedly and asked.

Mu Feng'er said: "The casting of magic skills has nothing to do with Xuandao cultivation, the key is to look at the purity of the elemental power and the level of perception. ”

"What is perception?" A student asked.

"Teacher Mu, you haven't told us about the grading of elemental power." Another student reminded.

"It's time for class in a little while."

Mu Feng'er's gaze fell on the wall behind her.

There was a faint faint wisp of imperceptible mystical power fluctuations from behind.

Wu Yu's heart moved slightly, and he looked along her line of sight, but saw a disc-shaped artifact hanging on the wall.

Inside the object were three hands of varying lengths, which rotated at different speeds around the center of the disk, the longest of which turned very fast.

What is it?

He felt like he had never seen anything before, and he couldn't help but look at it twice.

The rest of the students also looked at it with curiosity, as if they had never seen this disc artifact before.

Mu Feng'er noticed their doubts and said with a smile: "This is called a clock, it is an alchemy artifact transmitted from the Western Illusion Federation, it is very convenient to judge the time, and every Xuantang Xuanfu is equipped with it." ”

Clock?

Wu Yu glanced at the clock again, and he could be sure that the faint fluctuation of Xuan Power came from the clock.

I think this clock should be based on Xuanli as the energy source.

However, what made him feel strange was that he had never been aware of the existence of the clock before, as if the clock appeared out of thin air at the moment when Mu Feng'er looked at the wall.

Wu Hao looked at the students again, and their faces did not have expressions such as doubts except curiosity.

Could it be that I didn't notice it before?

He wondered.

"Teacher Mu, you can continue to speak, we came to Xuantang just to learn more things, and we are not in a hurry to get out of class."

Looking at the hungry eyes of the students for knowledge, Mu Feng'er was relieved: "Since this is the case, then I will talk about the classification of perception and elemental power." ”

"Perception, as the name suggests, is a kind of perceptual ability, the ability to perceive energy fluctuations, perceive breath, perceive danger, etc."

Mu Feng'er glanced at Wu Yu intentionally or unintentionally, and continued: "Perception is innate, and it is difficult to improve it through acquired exercise, so people with high perception are often called perceptual physique. ”

"Perceiving the physique, you can easily perceive the elements of the outside world, so as to pull the elements to build magic skills."

"Teacher Mu, how do we know the level of our perception?"

"Perception is difficult to measure, so there is no hierarchy for perception for the time being."

Mu Feng'er continued: "However, you can try to sense the elemental fluctuations in the outside world. ”

"If you can perceive it, it means that your perception is high enough to try to build a magic skill."

All the students couldn't wait, they closed their eyes and stared, and some even crossed their knees and put on a posture of cultivation.

"I didn't let you try it now."

For the diligent actions of these students, Mu Feng'er felt angry and funny, "Try it slowly after class, and listen to the class now." ”

The students looked embarrassed and hurriedly sat down.

Mu Feng'er said: "The reason why I mention perception is to say that if your talent is good enough, you can learn the construction of magic skills early. ”

Wu Yu asked, "Teacher Mu, you said that I am a perceptual physique, so can I build a magic technique?" ”

Feel the physique!

The eyes of all the students once again focused on Wu Yu.

Long Tao's pupils shrank suddenly, and his eyes wandered.

"Perceiving the external elements is only a prerequisite, and in order to build a magic skill, you also need to mobilize the external elements through the power of the elements."

Mu Feng'er glanced at him and struck mercilessly.

Everyone looked away.

Long Tao breathed a sigh of relief, and the thought of revenge reappeared in his heart.

Wu Yu was silent, silently operating the Xuan Force, trying to mobilize the elements he perceived.

Mu Feng'er didn't stop his useless work, and continued: "Most people's perception is at a normal level, and they can only perceive external elements with the help of elemental power, and this method has certain requirements for the purity of elemental power. ”

"The power of the elements is divided into five levels: mortal level, danger mystery, calamity, calamity, and extreme according to the purity of the essence."

"As long as you reach the mortal level, you can preliminarily construct a magic skill."

Speaking of this, Mu Feng'er obviously felt that the atmosphere below had become restless.

Some students couldn't hide their excitement and asked, "Teacher Mu, the mortal level is the lowest level, are we all considered mortal now?" ”

"Of course not."

Mu Feng'er said: "Just like the exercises, there is a distinction between grades and non-streams, and below the mortal level is also called the non-stream-level level. ”

It seemed that seeing that the mood of the students was lowered, Mu Feng'er encouraged: "Don't be discouraged, as long as you transfer to the Yellow Element Xuangong as soon as possible, it is not difficult to reach the mortal level." ”

A student raised his hand and asked, "Teacher Mu, then how can we judge that we have reached the mortal level?" ”

"Although these levels of elemental power are divided according to the level of refinement purity, since measuring refinement requires special instruments, in order to avoid trouble, people often extrapolate the level of refinement purity according to the power of magic skills."

"In other words, if you can initially construct a magic technique, it means that you have reached the mortal level."

"Although this method of judging is not necessarily accurate, what everyone cares about most is not the purity of the magic skill but the power of the magic skill, so when people talk about the level of elemental power, they usually refer to the power of the magic skill rather than the purity of the magic skill."

Wang Shangyou listened a little big, and couldn't help but ask: "Teacher Mu, I still don't understand a little, so is the level of elemental power divided by essence purity, or by the power of magic skills?" ”

"...... of these two divisions"

Mu Feng'er paused, although she understood the logic herself, she didn't know how to explain it more clearly.

At this time, Wu Yu said: "In theory, it is divided according to the purity, and in practical applications, it is divided according to the power of magic skills. ”

Mu Feng'er's eyes lit up, and she nodded: "That's it." ”

Wang Shangyou poked his head hard with his thumb, "I still don't understand, since it can be divided by the power of magic skills, why do you need to have the entire essence purity?" ”

Mu Feng'er was slightly stunned, and said in her heart: Yes, why?!

"Didn't Mr. Mu explain it very clearly, it was originally divided by refinement purity, but it is more troublesome to measure refinement purity, so it is divided by the power of magic skills." Wu Yu said again.

Mu Feng'er nodded vigorously, "That's it." ”

Wang Shangyou seems to understand whether he understands or not.

Wu Yu scratched his head, "Can't understand such a simple logic?" ”

Wang Shangyou glared at him, so he had to grit his teeth and say, "Of course I understand." ”

Wu Yu looked at Mu Feng'er and said, "Teacher Mu, he understands, you can continue to talk about it." ”

Wang Shangyou: "......"
