Criss-crossed, dense lines vibrating endlessly, weaving a dizzying and strange scene over the Charms classroom.

Many students have lost the tremendous mental pressure and have lowered their heads and used meditation to soothe their minds.

Professor Yao quickly sensed this.

He smacked his pipe, and with a wave of his arm, he tore open the curtains on either side of the classroom.

The golden sunlight of the afternoon shines through the transparent glass windows and falls between the students' desks, dispelling the darkness in the classroom, and also impacting the light blue light and quickly dissipating into the air.

An elf bravely rushed down from the edge of the blackboard and landed on top of the professor's head, flapping its wings, gathering the pile of smoke that Professor Yao had spit out into a ball and stuffing it into a small gray pot.

The professor raised his eyelids, one eyebrow raised, and glanced at the elf standing above him.

In the end, there was no wave to expel her.

"Ahem!" he put away his pipe, glanced around the classroom with a majestic gaze, and knocked on the blackboard behind him: "Attention, look at the blackboard...... Now for the main point of this lesson...... Of course, the previous ones are also important. ”

The classroom erupted in a light laugh.

I don't know if I think the professor's inconsistent words are funny, or if the elf standing above his head is funny and intently collecting the smoke.

"Dimensionalism believes that dimensions are measurable. ”

A blue dot of light appears on the blackboard.

It repeated its previous history in the dark, flickering and moving, leaving a slender trail in its wake.

Only this time, each of its displacements will have a formula as a footnote, along with the relevant concepts and examples, marked on the blackboard.

"Linear, nonlinear, probabilistic, distributed, winding, vibrating, etc...... In the eyes of the dimensionalists, dimensionality, or rather, the reality of this world, can be measured. ”

"For example, when you see this thin line, you may think that it has no beginning, no end, no length. This is a delusion...... Because what you see is the structure that I enlarged during the lesson, to be precise, the length of this thin line is 1.616x10^-35m. ”

This value was determined by the great wizard Planck in 1900, so it is called Planck length...... What are you doing in a daze? Write it down, this is the final exam point!"

Lao Yao saw that several boys in the back row of the classroom were staring blankly at the blackboard, and immediately knocked on the blackboard, dragging a long tone and teaching: "Don't just memorize the content on the blackboard, you must write down these things I mentioned in the lecture...... Why don't you take notes?"

The orange cat looked up, gave the professor a stupid look, and then quickly turned his head to look at the young public-funded student.

Report Professor...... His hands hurt..."Zheng Qing was sweating profusely, and finally pulled a reason that no one believed, and explained hard: "I didn't bring silkworm skin gloves to the experiment yesterday, so I ......"

"So you're helping him take notes?" Professor Yao squinted and snorted.

Zheng Qing shrunk his neck and whispered.

Many people in the classroom turned their heads curiously and looked at the round orange fat man. Even the dullest of the human can sense that something is wrong.

But since the professor didn't make it clear to his face, others wouldn't rush up to question it in a daze.

At most, a few meaningful laughs and a few playful glances.

Lao Yao didn't spend too much time on the fat man's notes, but continued to speak, and said slowly: "...... As for the nature of magic...... In the eyes of the Dimensionalists, magic is nothing more than the embodiment of changes between dimensions...... Either from a higher dimension to a lower dimension, or from a lower dimension to a higher dimension. ”

As he spoke, he re-clicked a blue dot in mid-air.

This blue point of light repeats the process of changing from a point, to a line, then to a surface, to three dimensions, to six dimensions, rising and changing, until finally breaking back into a blue mist.

And those disturbing flickering blacks still appear where the dimensional lines break.

The thin blue lines spread to all corners of the classroom, and the orange cat in front of Zheng Qing seemed to be very interested in them, stretching out its paws again and again, trying to play with those blue thin lines.

This made the young student so angry that he had to lean out again and again, grab it by the neck, or grab its tail, to dispel its impulse, and remind the cat that it was not a cat now.

"Attention, the point is here!" Professor Yao tapped vigorously on the blackboard, reminding the various uneasy young wizards in the hall, raising his voice slightly, and said word by word in an emphatic tone:

"In general, when the motion of a dimensional line decreases from a higher dimension to a lower dimension, a large amount of energy is released, and when a dimensional line rises from a lower dimension to a higher dimension, it absorbs a large amount of energy. ”

"The Dimensionalists believe that the spells cast by wizards are achieved through this energy fluctuation generated by dimensional line jumps. ”

Zheng Qing immediately gave up his plan to stop the orange cat from dying, grabbed the brush in his hand, and quickly took notes.

Even the most dull person can understand what the professor just said meant.

It is no exaggeration to say that the sentence just now is the truth of the wizarding world.

Professor Yao did not slow down in the slightest because he had just talked about an important concept, on the contrary, he even sped up slightly in the next sentence:

“...... As for the origin of the world, the dimensionalists believe that, like the Tao, the origin is indescribable, a very large set, a very high dimension, and cannot be described. ”

"But Professor, you just mentioned the methodology of the dimensionalists, saying that dimensions can be measured. A questioning question rang out in the classroom.

It was Liu Feifei, Zheng Qing didn't need to look up, he could distinguish the thin voice.

"Very keen!" Lao Yao unabashedly approving: "He is worthy of being our chief student...... It's too big to describe, what should I do? The Dimensionalists came up with a solution—convergence. ”

“limit。 He turned around and wrote a symbol of the dragon flying and the phoenix dancing on the blackboard, and then explained:

"By converging, the characteristics of the 'source' are strengthened, so that wizards can interpret it more easily...... When the source converged to the point where it could be deciphered, converging into a magic circle and a spell, the wizards were horrified to find that they had opened Pandora's box. ”

At this, the professor paused, as if considering the wording. Everyone grabbed their pens and waited quietly for the professor's next sentence, and the classroom was so quiet that they could hear the needles on the ground.

"Forbidden spells. Xiao Xiao muttered.

Although his voice was very low, it was unusually abrupt in the quiet classroom.

Professor Yao didn't show any dissatisfaction, but narrowed his eyes and showed an approving smile: "Yes...... Yes. This is where the forbidden spell comes in...... The source converges to the point where it can be expressed in magic, which is a forbidden spell. ”

This is also the reason why the Dimension School has become the most powerful philosophical school in the last hundred years...... They proved that they were so close to the origin with forbidden spells, shattered the supreme glory of the gods with forbidden spells, and shattered the world that traditional wizards had lived in since the Middle Ages. ”

"Before the birth of the forbidden spell, the wizards' most offensive magic was born in the 'Five Fireballs Faction', and the wizards at that time believed that there was no guardian that could not be broken by five fireballs, and there was no obstacle that could not be broken by five fireballs...... Of course, this is an exaggeration, and the real wizards of the Five Fireball Sect are not only throwing five fireballs. ”

"After the birth of the forbidden spell, the slogan of the wizards became, 'There is no world that cannot be destroyed by a forbidden spell, and if there is no destruction, it means that the forbidden spell is not precise enough'. ”
