Take control of thunder and lightning from Hogwarts

Chapter 87
For example, many spells that need to release elements, such as 'Clear Water Like Spring', 'Blooming Flames', etc. use 'Elemental' Rune as the base. What effect do you want this spell to play, and then give these bases? Rune combination on other rune. "

"It turns out to be the case, that is to say, the spells that do not change the shape of objects are basically 'control', those that change the shape use 'change', and the elements of the element type use 'element', right? Are there other types? ?" Anduin asked curiously.

"Of course there are, many memory magics use 'thinking' runes, and like many black magics, like the Unforgivable Curse, they use 'soul' runes. Soul-related magic is very complex and profound. It is difficult to develop counter-curses and de-curses, which is one of the reasons why this type of magic is banned." Bones explained in detail.

After solving the doubts in his heart, Anduin continued to explain his idea to Professor Burns: "After I used 'control' as the base, considering that this spell needs to send out sound waves first, then retract the sound waves, and receive them by receiving Factors such as the time interval and orientation of the sound waves, trying to achieve a positioning effect, so I combined 'sound', 'emission', 'induction', 'present' and other spells."

"Oh? Then show me the rune combination you imagined." Borns heard that Anduin had already had enough practical ideas, so he wanted to see how the progress was by observing the rune combination.

"Okay, professor." Anduin skillfully mobilized the required runes and combined them according to the previous progress. Professor Burns's rune table contains a lot of runes and runes, so there is no such thing as The case of which character is missing when combining.

Borns looked at the combined rune and said with a smile to Anduin: "Have you tried this spell, your magic control is very good, you should try it, what is the effect?"

Anduin nodded and said, "Indeed I tried it, but after casting the spell, the spell just buzzed, didn't do anything other than make a noise, and didn't get any echo feedback."

"What do you think is the reason?" Burns said.

"My charm is to simulate ultrasonic waves, so higher frequency sound waves are needed. I think it should be the reason that the frequency of sound waves is not enough." Anduin said his thoughts.

"I think I see what you mean, but you got this spell wrong in one place," Burns said, observing Anduin's spell.

"Where?" Anduin's heart moved, and sure enough, the professional was different.

"Here." Borns said, pointing to a spot on the Anduin rune.

"Is there a problem with the 'presentation' rune?" Anduin asked in confusion.

Borns nodded and said: "Yes, your idea is to emit high-frequency sound waves and then receive them, and then detect the surrounding environment for you. Is that right? How far can you imagine?"

Anduin thought about it and said, "The ultrasonic speed is very fast and the stability is strong. It should be able to sense a radius of at least [-] meters. If it is optimized by runes and some spellcasting skills, it should be able to detect situations within a kilometer range. no problem."

such a wide range?Borns was secretly surprised, although he didn't know what Anduin was talking about, but if he could really develop such a wide-ranging detection spell, it would have a very broad application prospect. , and his horizontal perception range is about tens of meters.

Borns nodded secretly in his heart, and then said to Anduin: "Okay, then have you thought about it, such a large detection range, how will you show it after receiving it, with ears or eyes, if it is attached to the eyes, yes It may interfere with your vision."

When Anduin heard it, he couldn't help but be stunned. Indeed, he thought very well. Where would the recovered sound waves be transmitted to after receiving them? The ears are definitely not good, but the eyes are fine, but if the eyes are full of sound waves, it will even interfere with normal. When testing vision and spells, what should I do if I accidentally blind myself, and this kind of echolocation, Anduin envisions it as a 360-degree detection mode with no dead ends. If you use your eyes, you can only see one. direction.

Borns looked at Anduin who was thinking, and explained to him: "Actually, your idea is very good. This spell has a good application prospect. Its biggest role should be to detect the situation behind bunkers or obstacles. Or an environment with poor visibility, such as woods or something?"

Anduin nodded and said, "That's right, and I imagine people using disillusionment spells or wearing invisibility cloaks can be observed."

"Oh?" Borns didn't expect this, but it increased the value of the spell even more, so he went on to explain: "I offer you two ideas, the first is to pass feedback to your mind. In that way, you can directly visualize the environment covered by the spell in your mind. I remember that there is a similar application in the rune of Legilimency, but it is very difficult to develop and the risk of experimenting is very high. So I don't recommend you do this.

The second is to change your thinking and take apart your spell. You can try to receive and present information with the help of alchemy props, such as a mirror, or a pair of glasses, which are sent out by the spell... um, that ultrasonic wave, Then it is received by alchemy items, so it is safe and the development difficulty of the spell is also low. "

"Understood, then I am willing to accept the second method." Anduin replied after thinking for a while.

Sure enough, experienced scholars have very clear ideas, Anduin thought silently.

"Well, let's go here today. You need to do what I said. You still need to learn a lot of things, including material science and enchantment. I will explain these to you later."

After coming out of Professor Burns' office, it was time for the curfew. Anduin thought about it and decided that he should go back to the Slytherin dormitory to rest today.

As he walked to the basement, Anduin recalled what he had learned today. Professor Burns was worthy of being a master of spells. The amount of information he had received today was more abundant than what he had been taught by himself.

Just as he was walking and wanted to come to the third floor, Anduin suddenly heard a rustling sound behind him, and as soon as he looked back, he saw two dark shadows hitting him.

Instinctively cast the barrier to bounce the two shadows away, only to see the shadows explode immediately after hitting the barrier, and a stench hits the face.

"Big dung bomb?" Anduin constantly mobilized the air around him, blowing away the filth and stench, and then quickly hid behind the stone pillar beside him, looking for the attacker, but the attacker had long since disappeared.

He came to attack me at the beginning of school, who could it be, [-]% of the Travers gang, with big dung bombs?Childish, Anduin thought, frowning.
