Illusion magic is the image that is determined by the mind, and for the students below, it is no longer a problem to penetrate consciousness into magic. A few of the students have begun to conjure up various shapes, such as chairs, other people, and dragons, but these illusions are all false images, different from real transformations.

Vasileb was also very happy to see the enthusiasm of the children, clapped his hands, and asked the students to calm down: "Okay, stop playing, it's a magic theory class, not a practical class, and it's not a practical class." Now that you've memorized some of the illusion techniques I've just taught, let's move on to the second lesson, stealth magic. ”

As soon as these words came out, everyone really calmed down. Stealth magic is not something that can be learned in the textbooks of ordinary colleges, that is, it is not extensive magic, most colleges do not teach students directly, and the secret magic book on the first layer of the big blue crystal tower also collects the learning methods and skills of this magic.

Vasileb looked at the crowd and said in a shocking voice: "Can stealth magic really be invisible? There is one kind of magic that can, and there is one that can't, and I only teach you the stealth magic that can't be 'invisible', because the other is listed as a forbidden art." If you really want to learn the second type, you have to rely on your own skills to enter the second layer of the Great Blue Tower. ”

All the students in the audience were talking and amazed. Even Ursula didn't know that there were two kinds of stealth magic, one of which was forbidden.

"What's the use of learning invisibility magic that can't be invisible?" shouted a student who couldn't resist it with sound magic, but his amplification effect was obviously not as good as that of the teacher.

"yes, yes. This is also what other students wonder.

"Please be quiet, please be quiet. Washileb said: "Listen to me, and you will know." When I say invisibility magic that can't be 'invisible', I mean that it can't actually be invisible, but it can be effective. Many students may wonder if they can use illusion to achieve the effect of turning into air and thus becoming invisible, and I tell you, it is still illusion. Although invisibility magic and illusion magic are also after invisibility, your essence still exists, but it is just invisible, but they are fundamentally different. ”

The audience listened quietly. Seeing that Sofina was about to ask another question, Bing Zhiyi hurriedly said, "I don't know." ”

Sofina almost didn't laugh when she saw him so flustered.

Ursula wanted to return to Sofina's question, but he didn't know much about invisibility magic, so he sighed.

"Everything we can see visually is transmitted through the medium of light, and we must see the size and color of the object through the intensity of the reflection of light," Waschille said. For example, if you see me standing here in a white magic robe, this is the effect of light. To use another analogy, when we see the stars and the moon at night, we see them through the reflection of light. Is the moon round and absent, and when it is missing, that part of the moon does not exist? No, it's just that there is no light on that side, reflected in our eyes. The same is true of so many shining stars in the universe, but there is no light in those dark places? No, there is just nothing to reflect it. That is, when light does not enter our eyes, we cannot see its existence. ”

Everyone nodded their heads, as if they understood, but not very clearly. A few smart people have come to their senses, and this is what happened to their hearts.

Seeing the expressions of those smart people, Vasileb smiled and said, "Actually, it's very simple, as long as you understand this magic principle, you will know the direction of learning, no matter what kind of magic you learn." To be invisible, you have to meet the above two conditions: first, not let the light hit you, and second, let the light that does not hit you reflect to the eyes of others. It's not difficult to do both, but like illusion, you need to have a lot of magical control. ”

He paused and continued: "First of all, learn the first point, don't let the light shine on you, this light magic and space magic are easy to do, and other systems can also be blocked through magic reflective elements. But if you don't reflect the blocked light into the eyes of others at a normal angle, they will see that there is a dark mass, like this. ”

As soon as he finished speaking, the student saw that the teacher's body darkened, turning into a vague and dark human figure standing there, and couldn't help but laugh, but there was also admiration.

Vasileb showed his original form and said: "If the reflection range of this darkness is too large, it will be a black ball, so that the light will be reflected when it is about to stick to you, so that it can have a more haode effect." The second thing you have to do is to make the darkness disappear, which requires you to control the reflection of light with extreme control. Originally, the light should be directly irradiated, and it will be reflected when it touches anything, what we have to do is to let the light shine down normally, and send it out at a reasonable angle without touching you, so that you are invisible. Please look at me. As soon as he finished speaking, he disappeared without a trace.

The students were amazed and applauded.

"But there are a few things to keep in mind: first, you need to control the angle at which the light is reflected, otherwise there will be visual distortion. Vasileb was still invisible, but the scene behind and around his body reflected into the eyes of the students became crooked: "Second, it must be in the smallest range, preferably to reflect the light close to the body, so that it is easier for people to detect the beating of your magic power, and the following effects will not appear." ”

I saw that the range of his reflection expanded, and the platform under his feet, the surrounding trees were half gone, and half were still exposed, and the students laughed.

Wasileb appeared: "Anyway, that's it, the theory of stealth magic is very simple, but the actual operation is very difficult, if you want to learn it, you can learn it, it doesn't matter if you can't learn it, just understand it." He explained the tricks and methods in great detail, and he didn't stop until the end of the class, and Zuihou said: "After talking for so long, you have asked so many questions, my throat is smoking." It's time for class, so try it yourself. I'll have a chance to teach you again, zaijian. ”

The students applauded and couldn't wait to try it themselves. Sure enough, it was the same as what the Great Wizard Swashileb said, either he couldn't control the light well and made his vision messy, or he couldn't grasp the pan encirclement, and he rolled into it with the classmates next to him. Some ingenious students decided to practice one skill at a time, and as a result, the first to practice the reflex angle either made the body upside down, or the body was fat and thin, and the visual appearance of half human and half dark on the other side made the surroundings laugh. ,

Irina and Cornelia sit together, and they're also studying trials. One of them is a knight of the main light system, and the other is a magician of the main space system, and these two have the most advantage in guiding and controlling the light, and they have a magic effect, which is really much better than others.

Ursula was also trying, but she didn't make it out of the ordinary: "Damn, it's super hard magic to learn." ”

"Will you?" asked Sofina.

Bing Zhixiao shook his head: "No, but I want to learn." ”

"Oh, you're also interested in stealth?"

"It's not. "If you learn this magic, your ability to control yourself will improve dramatically, and I think that's why Mr. Archmage will teach the staff stealth magic." As he spoke, he himself used his magic power to try several times, but after the third attempt, he had completely disappeared.

The people around him were so surprised that their jaws almost didn't dislocate, and Ursula was even more shocked, he could understand the difficulty of this magic very well: "God...... Genius?"

Bing Zhiyi appeared: "Well, it's easy. Teacher, I'm leaving. ”

Sofina was also secretly frightened, she could see that this was not a genius who could learn it as soon as he learned it, but that his own magic control ability had reached this point, and said with a smile in her heart: "What a smart boy, you can see at a glance my grandfather's intention to teach this magic, and my grandfather also taught me this way back then." ”

"Hey, wait a minute. Sofina chased after her and said, "I'm not going home to cook food today, I'll take you to the restaurant to eat delicious food." What do you want to eat?"

Bing Zhixiao raised his head and said, "Is it really okay to do anything?"

Sofina suddenly remembered the food he ordered that time, and couldn't help but shudder, and whispered: "I spent almost all my money last time when I bought clothes and furniture, and I have to spend this month, can I eat cheaper?"

"Oh!" said Ice Childish, with a look of disappointment.

Sofina couldn't stand it: "Okay, well, you can eat whatever you want." ”

Bing Zhixiao smiled: "Yes, I want to eat pearl agate eggs, sago dew, crab salad with orange juice, lamb rump meat, shark fin in Tianjiuda, mushroom shark meat pizza, fried veal steak with black pepper and osmanthus nectar sauce, two-flavor shrimp, and abalone winter melon balls, if the abalone is on the haode four-headed net abalone, it will also ......"

"Hey, hey, hey, stop, stop. Sofina covered his mouth and said, "That's enough, you can't eat any more." ”

"Okay. Bing Zhixiao took the initiative to take her hand and left with her. That way, she can feel at ease.

Luo watched from afar: "When did he have such a good relationship with Teacher Sofina?"

Vane said, "Do you think that the ice and evil seem to have changed? ”
