#87 - Change of mindset

For example, many spells that require releasing elements, such as 'Aguamenti' and 'Incendio,' use the 'Element' rune as their base. If you want the spell to have a certain effect, you can combine these base runes with other runes. Read more.

"I see. So, spells that don't change the shape of an object basically use 'Control,' those that change shape use 'Transformation,' and elemental spells use 'Element,' right? Are there any other types?" Anduin asked curiously.

"Of course, there are. Many memory charms use the 'Mind' rune, while many dark spells, like the Unforgivable Curses, use the 'Soul' rune. Soul-related magic is very complex and profound, making it difficult to develop counter-spells and jinxes, which is one of the reasons why these spells are forbidden," Bones explained in detail.

After resolving his doubts, Anduin continued to explain his idea to Professor Bones: "After using 'Control' as the base, I considered that the spell needs to emit sound waves first, then retrieve them, and try to achieve a positioning effect by receiving the time interval and direction of the sound waves. So, I combined the 'Sound,' 'Emission,' 'Sense,' and 'Presentation' runes."

"Oh? Then show me the rune combination you envisioned." Hearing that Anduin already had enough practical ideas, Bones wanted to see how far he had progressed by observing the rune combination.

"Okay, Professor." Anduin skillfully summoned the required runes and combined them according to the previous progress. Professor Bones's rune platform contained a large number of runes, so there was no situation where any characters were missing during the combination.

Looking at the combined runes, Bones smiled at Anduin and said, "Have you tried this spell? Your magical control is very good, you should have tried it, right? What's the effect?"

Anduin nodded and said, "I did try it, but after casting the spell, the rune just hummed, and it was useless except for being noisy, and I didn't receive any echo feedback."

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

"My rune wants to simulate ultrasound, which requires higher frequency sound waves. I think it should be because the sound wave frequency is not enough," Anduin said his thoughts.

"I think I understand what you mean, but there is one thing you got wrong with this rune," Bones said, observing Anduin's rune.

"What is it?" Anduin's heart moved. As expected, professionals are different.

"Here," Bones said, pointing to a spot on Anduin's rune.

"Is there a problem with the 'Presentation' rune?" Anduin asked, puzzled.

Bones nodded and said, "That's right. 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 the range?"

Anduin thought for a while and said, "The speed of ultrasound is very fast and the stability is strong. At least it should be able to sense a radius of 100 meters. If it is optimized by runes, plus some casting skills, it should be no problem to detect the situation within a kilometer."

Such a wide range? Bones was secretly surprised. Although he didn't know what Anduin was talking about ultrasound, if he could really develop such a large-scale reconnaissance spell, the application prospects would be very broad. As a sensing magic, his level of Supersensory Charm can only sense a range of about tens of meters.

Bones nodded secretly in his heart, and then said to Anduin: "Okay, then have you ever thought about how to present it after receiving such a large detection range, with your ears, or with your eyes? If it is attached to the eyes, it may interfere with the original vision."

When Anduin heard this, he couldn't help but be stunned. Indeed, he thought it was good. Where should the returned sound waves be transmitted after receiving them? Ears are definitely not good, eyes are okay, but if the eyes are full of sound wave patterns, it will even interfere with normal vision. During the rune test, what if he accidentally blinded himself? Moreover, in Anduin's vision, this kind of echo positioning is a 360-degree blind spot detection mode, and the eyes can only see one direction.

Bones looked at Anduin who was thinking, and explained to him: "Actually, your idea is very good, this kind of spell has good application prospects, its biggest role should be to detect the situation behind obstacles or obstacles, or in environments with poor visibility, such as forests, right?"

Anduin nodded and said, "That's right, and in my vision, I can also observe people who use the Disillusionment Charm or wear an Invisibility Cloak."

"Oh?" Bones didn't expect this, but this added to the value of the rune, so he continued to explain: "I will give you two ideas. The first is to transmit the feedback to your mind, so that you can directly present the environment within the scope of the spell in your mind. I remember that there are similar applications in the 'Legilimency' rune, but the development difficulty is very high and the risk of experimentation is also very high, so I don't recommend you to do this.

The second is to change your thinking and disassemble your runes. You can try to use alchemy props to receive and present information, such as a mirror or a pair of glasses. The spell emits... uh, that ultrasound, and then the alchemy props receive it, so it is safe and the development difficulty of the spell is low."

"I understand, then I am willing to accept the second method," Anduin thought for a while and replied.

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

"Okay, let's stop here today. To do what I said, you still need to learn a lot, including material science and enchantment. Next, I will explain these contents to you."

After coming out of Professor Bones's office, it was past curfew. Anduin thought for a while and decided to go back to the Slytherin dormitory to rest today.

While walking towards the basement, Anduin recalled today's gains. Professor Bones is indeed a master of runes. The amount of information gained today is richer than what he has learned on his own.

Just as he was walking and thinking, when he came to the third floor, Anduin suddenly heard a rustling sound behind him. As soon as he turned his head, he saw two dark shadows hitting him.

Instinctively casting a barrier to bounce the two shadows away, he saw that the shadows exploded immediately after hitting the obstacle, and a stench came over his face.

"Dungbombs?" Anduin constantly mobilized the air around him to blow away the filth and stench, and then quickly hid behind the stone pillar next to him, looking for the figure of the attacker, but the attacker had already run away.

Attacking me as soon as school starts, who could it be? It's probably Travers and his gang, using dungbombs? How childish, Anduin thought with a frown.
