(I found out that the title of the private book has always been wrong.,Cover your face.,I'm too lazy to change it.,It's the cute point of the book title.。 Anyway, it doesn't affect reading and comprehension. ）

"Lady Sibruz! This is an insult! Marik Lum with a cold is insulting me! Louise said, clenching her fists and banging on the table.

"You say I have a cold? I am Marik Lum on the wind. I didn't have any colds! ”

"Isn't that rumbling sound of yours like you have a cold?"

The boy named Marik Lum stood up and glared at Louise. Sibruz waved his wand. The two people who were standing brushed down like puppets with broken strings.

"Miss Vallière. Mr. Mariklum. Stop this humiliating rhetoric. Louise nodded listlessly. The arrogant attitude on his face just now disappeared all at once.

"It's not okay to call a classmate zero, a cold or something. Do you understand? ”

Ms. Sibruz's original intention at first was to congratulate Louise, because of her efforts, Ms. Sibruz has always been in the eyes, and it is really good that this time the ceremony can be successfully completed.

Lady Sibruz had heard about Louise's enchantment being a human and possibly a magician, and she was very happy for her.

But Louise's skipping class yesterday afternoon and dozing off during today's class time made Lady Sibruz angry. So she woke up Louise and wanted to warn her.

However, as a school teacher, Ms. Sibruz underestimated the nasty brains of adolescent boys, and how these aristocratic children could think of things so dirty and indecent to get involved with the transaction, as a school teacher, Ms. Sibruz knew how sacred and difficult it was to interfere with this ritual.

And Mr. Gruberu, who is in charge of guidance, don't look at him as a professor now, but his strength is unfathomable! His strength is only at the "Triangle" level, and Mr. Gruberu is at least a great magician at the Quartet level!

This is also the reason why the headmaster has given Mr. Gruberu a heavy responsibility, no one can cheat under the nose of the great magician of the Quartet level, not even the children and grandchildren of the nobles!

So for the clamor of the students, mainly the boys, the kind Ms. Sibruz is actually very dissatisfied, but she can't have a seizure, Mr. Gruberu is a quadripartite level, and she is only a triangle level. In this world, the power of magic is absolute.

"Ms. Sibruz, calling me cold is just a slander, but her zero is the truth." Marik Lum smiled secretly as he spoke, and there was no shortage of people around him who agreed.

Ms. Sibruz looked around the classroom with a stern expression. Then he waved his wand. Out of nowhere, the red clay shut the smiling student's mouth, and that was the limit of what she could do for Louise with her professor's authority.

"You can continue to listen to the lecture for me like this!" The laughter in the classroom was gone.

"Then let's start class." Sybruz coughed heavily and waved his wand. A lot of small stones appeared on the table.

"As everyone knows, my title is terracotta. Terracotta Sibruz. I'm going to teach you a year of earth-based magic from now on. Do you know the four systems of magic? Mr. Mariklum! With that, Siburz unlocked Mariklum's magic.

After all, Sibruz can't really let students really be gagged with mud in a single class, and a small punishment is enough.

"Yes, yes. It is the four major systems of fire, water, earth and wind. Marik Lum said with some nervousness.

Sibruz nodded.

"Together with the now lost Void System, there are five major systems, and these are as you know. And among the five major systems, the soil system occupies a very important position, at least I think so. ”

"It's not just because I'm a dirt system. It's not like I'm saying that. Sibruz coughed heavily.

"Earth system magic can be said to be the composition of all things. Quite important magic. ”

"Without this magic, you can't make important metals, you can't process them. You can't cut stones to build houses, and you may have to work by hand to harvest your crops. Therefore, the magic of the earth system is closely related to our lives. ”

The students in the classroom listened attentively, and even a tired Louise had to brace herself for fear of being suddenly gagged with dirt by the kind Lady Sibruz.

However, unlike everyone's wide-eyed and attentive listening, Seamus's eyes were also wide-eyed, but his eyes widened in surprise.

At Hogwarts, even the oldest wizarding families, such as the Malfoys, know that the basic elements of the physical world are particles. Elemental atoms composed of elementary particles such as electrons, protons, and neutrons are periodically distributed according to their properties.

Ever since the Muggles invented the atomic bomb, no magician dared to underestimate Muggle technology, and even the ancient families had to admit that Muggles had the power to destroy them in an instant.

Fortunately, this weapon is always manipulated by man, and if it is human, it can be manipulated by magic. This is also the reason why wizards are comfortable watching Muggles develop superweapons.

If the atomic bomb does not get out of the silos, then it will only be a dead thing with deterrent effect.

But Muggles' exploration of the world of technology also opened the door to new worlds for wizards, and more and more wizards began to notice Muggle technology.

They noticed that Muggles had spent centuries accomplishing things that could only be done with spells, and that the pace of research was accelerating.

"Sooner or later, Muggles will be able to rely on the power of science and technology to discover the connection between spirit and matter, and discover the mystery of the particles of spiritual communication, and then there will be no Muggles, and there will be no magicians, because there will be no difference between people in the end."

This is what Seamus saw from a novel, which seemed to him to be more like a prophecy, but it was listed as ** by the Ministry of Magic because it was too forward-looking. The Muggle government, though it did not ban its release, only regarded it as a fictional fantasy, after all, no one except a few in power knew that the wizarding world really existed.

However, what does Seamus hear here? The four systems of fire, water, earth and wind? Early research arguments of the Pythagoreans?

In the fifth century B.C., the basis of magic theory that ruled mankind for more than 2,000 years, was pioneered by the great prophet Empedocles of the classical era, and then perfected by the more famous master Aristotle?

In fact, Seamothon guò "Hogwarts: A School History" knows, well, in fact, Miss Hermione, who knows all about it: "The founders of the great Hogwarts School of Witchcraft and Wizardry actually founded the school according to this idea. ”

"Gryffindor represents fire, Ravenclaw represents wind, Hufflepuff represents earth, Slytherin represents water, and when the four elements coexist, they form a complete system. But as we all know, they are also independent. ”
