"Huh?" Alan wondered when he heard this, because Professor Sadles didn't name it, how did he recognize it as Cynthia?

But Cynthia seemed to have expected it. Instead of standing up immediately, she hesitated on the stool for a moment before slowly walking to the podium, without glancing at Sadres.

"Please smash the stone brick that was placed on the podium. Professor Sadres said.

Alan took a closer look and saw that there was indeed a small stone brick on the lectern, exactly the same as the one used to pave the road on campus.

"Isn't it a little too dangerous? If the flying debris hits someone, they might get hurt. Alan thought. Because judging from the content he previewed, thunder elemental magic is one of the most powerful types of magic among all elemental magic, and it is easy to cause accidental injuries if used at will.

The students sitting in the front row also involuntarily moved back, trying to get as far away from Cynthia as possible.

But Professor Sadres didn't seem worried.

"Hmm...... But since the presenter is Cynthia, with her ability, she should be able to grasp the proportions......" Thinking of this, Alan was also a little relieved.

Cynthia didn't do much preparation, using the levitation charm to move the small stone brick from the lectern to the ground, took two more steps back, and closed her eyes.

The whole classroom was silent, and all the students held their breath and watched quietly.

Cynthia didn't let everyone wait too long, and after only about ten seconds, she suddenly opened her eyes, and the calmness in her eyes had completely dissipated, replaced by firmness and sharpness that Eren had never seen. Without hesitation, she raised her wand and said aloud, "O lightning in my life...... Obey the call and be driven by me!"

I saw several red lights flash around Cynthia's body in an instant, accompanied by a slight "beep" sound, and as the wand in her hand waved downward, one of the red lights hit the brick at a speed that the naked eye could barely keep up with.

"Smack!" Perhaps indoors, the crisp popping sound was quite loud. The crowd looked around and saw that the entire brick had been smashed to pieces. However, it seems that she has a fairly precise control over the power, as there is not a single trace left on the ground except for the bricks that have been smashed to pieces.

"Well, that's good. Ten points!" Professor Sadres nodded, "Please get back to your seat." ”

Cynthia put away her wand and walked back to her seat. The red lightning that swept by her from time to time disappeared, and her eyes returned to a calm and calm appearance.

"Awesome job!" Alan whispered excitedly congratulatory.

But Cynthia didn't speak, just gently picked the corners of her mouth, and laughed.

"Why does she look unhappy?" Alan wondered. From the moment they stepped into the classroom, Alan felt that Cynthia's mood didn't seem right, she seemed quite low-key here compared to the morning, as if she was deliberately hiding herself, as if she had something on her mind.

But after all, this is a class, and Alan doesn't want to ask much.

"This is the autogenous thunder-like elemental magic, which is commonly known as the 'lightning spell' standard spell and action commands. Professor Sadres' voice rang out again.

As he paced, he said, "Generally speaking, autogeneous elemental magic is not very powerful compared to manipulative elemental magic, but they have a wide range of applications and are the basis of every elemental magic. Most of their spells are similar, and the spells of the Thunder Spell are just like Miss Winslow just recited, so you must remember them. Each step of the basic action instructions is detailed in the book, and I will not go into detail one by one. There are just a few things I need to remind you to pay attention to...... First, the mind should be highly concentrated during the casting process, otherwise the spell will not be able to be used smoothly due to insufficient or unstable mana output, second, the spell must be pronounced clearly and accurately, otherwise it will not be used correctly, third, each spell must be accompanied by roughly the same action commands, otherwise it may lead to misuse or failure of the spell, and fourth, and most importantly, fourth, and most importantly...... The landing point at the end of the action command must be accurate, and it must be accurate when you hear it clearly. Although this type of magic is not of the same level and power as magic formed by manipulating natural elements, it is still very lethal, and inaccurate landing is likely to cause accidental injury to people and animals. ”

"Hmm...... It seems that the lethality is indeed not small...... "Remembering that Cynthia had already made him lie on the ground for a long time unable to move due to an accidental leak of magical power, Alan was a little apprehensive and muttered quietly.

Cynthia heard and turned her head sideways, but stopped talking.

"Since we talked about basic elemental magic, we have to touch on the mutual restraint relationship between these five elements. Thunder elemental magic, while incredibly powerful enough to restrain some other elemental magic, can also be countered by others...... So does anyone know that there is a mutual restraint relationship between thunder elemental magic and which elemental magic, and elaborate on it?"

Alan thought about it for a long time, and the question that Professor Sadres asked seemed to be only covered in the third chapter of "The General Theory of Elemental Magic", and Alan only read the first two chapters carefully when he was previewing yesterday, and the third chapter was only a general glance.

He glanced at Cynthia in front of him, who was staring at the textbook with her head down, as if she didn't know the answer.

There was silence in the classroom, and it was clear that no one else had pre-read the chapter.

"So...... Miss Cynthia Winslow will be the answer. Professor Sadres waited for a moment to see that no one had answered, and then said.

Cynthia didn't seem to be willing to answer, and hesitated for a moment before standing up as before, and said slowly: "Under normal circumstances, thunder elemental magic can restrain earth elemental magic, but at the same time, it can be restrained by wind elemental magic. ”

"Then please elaborate as much as you can. Professor Sadres added.

Cynthia sighed softly and thought for a while before saying, "There is a mutual restraint relationship between each elemental magic, but it is not that one elemental magic must be restrained by another...... For example, normally, the flame will be extinguished by water, so the same or low level of fire elemental magic will be restrained by the same or higher level of water elemental magic, but there are special cases, that is, the flame is extremely hot, and the water will not extinguish the flame, but will be evaporated, which is manifested as the low-level water elemental magic is restrained by the high-level fire elemental magic...... In the same way, although the earth and stone are hard, in most cases, their hardness is not enough to resist the great power of thunder and lightning, so the earth element magic will be restrained by the thunder element magic, but because the hardness of the stone will increase with the increase of magic output, there will also be a phenomenon that the thunder and lightning cannot break the stone, at this time, it is manifested as the earth element magic restrains the thunder element magic...... In the same way, thunder and lightning are formed in clouds, and the wind can blow away or blow away the clouds, so normally, the thunder elemental magic will be restrained by the wind elemental magic, but there are also cases where the wind is too small to blow the thunderclouds, and then there is no mutual restraint between the thunder elemental magic and the wind elemental magic. ”

"Very nice and well organized. Professor Sadles looked satisfied, and nodded repeatedly, "Ten more points!"

Someone in the classroom began to mumble unsure what was going on, and Cynthia replied so fluently and completely, as if she already knew the answer to the question.

Alan also had 10,000 whys in her heart, Cynthia could have answered so perfectly but didn't raise her hand, and everyone didn't raise their hands, and Professor Sadres just picked her.

Don't...... An idea popped into Alan's mind.

"Well, I said...... Did you two know each other before?" asked Cynthia as soon as she sat down after answering the question.

Cynthia tilted her head slightly, and although she didn't answer the question after hearing it, her expression changed significantly. After a while, she lowered her head a little and said, "That's right...... Sure enough, you can see it. ”

"Then ...... him"

"He has been my personal tutor since four years ago. Cynthia said lightly.

"Since four years ago?" Although he couldn't say why, Alan vaguely felt that something was wrong.

"Well, I didn't know until I was admitted here that he would come along...... When I first saw his name on the bulletin board, I thought I had read it wrong. ”

"Didn't he tell you beforehand? or...... Your grandfather didn't tell you?"

"No, I don't know at all...... It wasn't until I was waiting for you downstairs that I saw him come in and I was sure it was indeed him. ”

Alan was even more curious when he heard this, it was no coincidence that a tutor who had been teaching the same student for four years suddenly came to school with his own students.

"And he knew early on that I would be assigned to the Thunder Elemental Department, so he came here to wait for me. ”

"Knew it early in the morning?"

"Well, you don't have to go through the Demon Tree to know the nature of your magic...... After all, there is only one demon tree, and not everyone has the opportunity to touch it. Cynthia looked up and explained slowly, "There is another way, and that is to experiment one by one by learning all the major magic, and the one that can successfully cast the higher level is the one...... Like you're doing right now. ”

"This ...... Isn't it troublesome?" Alan frowned and shrugged.

"It's really troublesome. Cynthia looked up, "But as you can see, it works too." ”

"And did he teach all your classes alone?"

"Yes, he taught all the basic elemental magic lessons, from theories to spells, by himself...... Although his primary attribute is thunder like me, he is familiar with all types of elemental magic spells. ”

"All!" Alan was a little surprised, "that's amazing!"

"But I seem to know what he's here for now......" Cynthia ignored Allen's compliment, instead turning her head to look at the podium. Professor Sadres was also watching her.

"For what?" asked Alan. He had been thinking about this question for a long time.

"If I'm not mistaken......" Cynthia still looked at Professor Sadles, but there seemed to be a little more hostility in her eyes, "he was there to keep an eye on my every move." ”
