"Hmm!" Alan nodded heavily, but Professor Wagbine didn't see it.

"The thickness of an enchantment is related to the amount of mana you consume, and its height is determined by the magnitude of your spellcasting. Professor Wagbyrne stepped back onto the podium and began to explain the details of the spell casting: "That is, the more mana you spend after you pronounce the spell, the greater the range of this enchantment can cover, the higher the physical attack it can withstand, and the greater the amplitude of your movements, the higher its height. However, you need to note that there is no standard to measure the cost of mana and the range of movement, and they are just feelings, so only if you practice a lot and become familiar with this feeling, can you be quick and accurate when you need to open the enchantment, and you will not waste extra mana. ”

"In order to make it easier for you to have a deeper understanding of the barrier barrier, I will talk to you in detail about the differences between the basic barrier barrier and the high barrier barrier through comparison. Professor Wagbein paused for a moment and continued, "The advantage of a basic barrier enchantment compared to a high-level barrier barrier is that it consumes less mana and is relatively easy to cast, but it also has the obvious disadvantage that it has a narrow range of application and can only be used on narrow terrain...... That is, if it is not used in long and narrow terrain, such as valleys, rooms, corridors, etc., the effect will be greatly reduced, because it will not be able to fully play its due role. However, the Higher Barrier Enchantment is different in that it can change shapes, so it is almost not limited by any terrain. The common square shape and this camouflage enchantment can form a closed structure on its own, so it can play its due role without relying on special terrain. And because this type of enchantment often involves attribute fusion, it is also functionally superior to the basic barrier enchantment. ”

Professor Wagbein's explanation was long, and some noise began to appear among the students, as if not all of them were listening to him. Little Stewart and Little Bilber, for example, were talking and laughing on the sidelines, not paying attention to the basics at all.

Professor Wagbine paused here until the noise died down before continuing, "But what I want to say is that both basic and advanced enchantments are equally important, and when they all have their functions, please be sure to treat them equally. Moreover, learning the basic enchantment course well is the foundation of learning the advanced enchantment course, and it is also the most important thing, so please keep this sentence in mind. ”

"Hmm. Most of the students nodded.

"Alright, let's stop!" Professor Wagbine said to his classmates who were still observing the enchantment, "Next, you have to learn how to break the enchantment. ”

I saw him put his wand on the barrier wall he had just laid down, and said aloud: "Like clouds and mist, invisible and invisible!" Then he heard a very soft "pop", as if something had broken, and the barrier barrier disappeared without a trace in an instant.

"The key to disarming the enchantment is to inject a little of your mana into the enchantment shell to disrupt the regular flow of mana that was originally formed by the action of the spell inside. There are no complicated action commands, and the spells are easy to remember. As he spoke, he instantly lifted the other barriers, "Then the next day, until the end of class, is the time for you to practice on your own." If there's something you don't understand, raise your hand and ask me. ”

The students scattered, each pulling out his wand and preparing to begin practicing.

"But I'd like to warn you not to make the enchantment too big when practicing, after all, we're also indoors. Professor Wagbine put away his wand, stepped off the podium, and began to walk among the students.

Alan and Cynthia still found the least personal corner to practice on their own. Fortunately, the area of this camouflage enchantment is very large, and there are still many secluded places.

Maybe it's because of the foundation left over when the old Adrian taught him to place the enchantment, maybe Alan is really talented in this area, he barely made any mistakes in the practice time of about half an hour, and the specific details such as the size, strength, position and direction of the enchantment are also very good, but Cynthia encountered a lot of trouble during the practice. The shape of the enchantment she emitted was strange, the enchantment laid by Alan and Professor Wagbein was smooth and regular-shaped, while the edges of her enchantment were jagged, and the color was heavy compared to that of Allen's cloth, and even occasionally flashed bright red.

Alan looked around and found that although the others had more or less problems with size and strength, the colors were quite normal, and only Cynthia was a little too special. He took a closer look at it curiously, and was surprised to find that the flow of magic in the enchantment shell she had planted was unusual. The magic in Eren's enchantment shell flowed very slowly, roughly in the same direction, in a steady and orderly manner, like a slowly flowing stream. However, the flow of magic in Cynthia's barrier wall was so fast that it was impossible to even see clearly with the naked eye, and the dazzling red light was a strange phenomenon caused by the accidental convergence of the originally scattered magic power, which caused the concentration of magic power to increase instantaneously.

"What's going on?" Cynthia asked, looking a little nervous. Originally, she was a representative of genius in the eyes of everyone, but now she encountered such an incomprehensible thing in the basic class.

Luckily, there was no one nearby, and she still had time to find out why.

"I don't know...... But I have a guess......" Alan looked at the enchantment and then at Cynthia, "Professor Wagbein said that this enchantment can be infused with magical properties, right?"

"Hmm......" Cynthia heard Alan ask, and suddenly understood what might be going on, and looked at Alan in a little surprise: "Is it ......?"

"When the surface of the enchantment is infused with magical properties, it will take on a new form and change its function...... That's what the book says, right?"

"Hmm...... But ......"

"So as it stands, it can only be like this. ”

"But I didn't, and I don't know what to do. ”

"You'll only know if you try it. Alan shrugged his shoulders, then slowly reached out his hand.

"Wait!" Cynthia tried to stop him, but Alan was closer to the barrier and had already put his hand on it.

At the moment when his palm made contact with the enchantment, he only heard a sound of "bang!", and Allen's whole person was bounced out, flying nearly two meters away!

"Ahh

All he felt was buzzing in his head, not just his arms, his whole body was numb now, and his heartbeat was so high that it was a little unbearable.

"Are you alright, Allen?Allen!" he vaguely heard Cynthia's hurried voice ringing in his ears, and he slowly turned his head to look in that direction, only to find that he couldn't open his eyes at all.

He was still conscious, and wanted to tell Cynthia that he could hear and tell her not to worry, but he didn't feel the strength to speak, so he had to shake his head slowly, but this seemed more uncomfortable to Cynthia.

Almost everyone heard the movement and looked to their side.

"What's going on?" After a rush of footsteps, Alan heard Professor Wagbein's voice coming from the other side of his body.

"This is what he did when he touched the barrier under my cloth!Please see if he's okay!" Cynthia sounded anxious.

Professor Wagbein touched Allen's forehead, then put his ear to his chest and listened for a few moments before looking up at Cynthia and saying, "Please tell me the details." ”

"That's what I just said!"

"Are you sure there is nothing else?"

"No more!"

Professor Wagbine looked a little surprised when he heard this, and pondered for a moment before saying, "You can show me another barrier." Be careful not to be too big, just the size of your palm. Can you do it?"

"Hmm!" Cynthia nodded, and immediately pulled out her wand, and placed another barrier at her feet that was exactly the same as before, but according to Professor Wagbyne's orders, this barrier was very small.

Professor Wagbein crouched down and looked at it for a few moments before he nodded and stood up, and said to Cynthia, "That's right...... It's a magical leak. ”

"He's alright, is he?" Professor!" Cynthia wasn't in the mood to care about leaks or not, she just wanted to know how Alan was doing.

"Don't worry, just let him lie here and rest for a while, it's fine. ”

"Hmm......" Cynthia ran to Alan and crouched down again.

"But it's really surprising to see such an obvious leak of magical properties...... It's still in the Thunder Elemental system. Professor Wagbine followed her.

"Professor, what is a magical leak?" Cynthia asked, knowing that Alan was fine.

Professor Wagbein didn't answer her immediately, but waved his hand away, drove everyone around Allen away, and sat down next to Allen.

"Generally speaking, the nature of the magic that exists in every human being is only manifested by the effect of spells...... However, you didn't pronounce the wrong spell when you placed the enchantment just now, and you didn't add a special spell fragment, but the nature of the thunder element in your body is still clearly manifested...... This is the leakage of magical powers. He explained as he fiddled with the blades of grass in his hand, not looking at all worried about Alan's condition.

Cynthia lowered her head and didn't speak, looking at the wand still clutched in her hand.

"I've seen someone set their clothes on fire for some reason, and someone disappeared from their teacup, but it's really the first time I've seen someone like this. Seeing that Cynthia didn't speak, Professor Wagbean smiled and continued, "But I really didn't expect that the elemental nature in your body would be so obvious...... Probably he didn't expect it either. ”

"Then ......" Cynthia seemed to have something to say, but opened her mouth and swallowed again.

"Don't worry, kid, it's just an accident, it doesn't happen very often. Professor Wagbein looked at her, as if he had guessed what she wanted to ask, "It won't bother you too much in your future studies and life." ”
