Mastering Lightning from Hogwarts

"The principle of the Echo Charm is similar to that of bats. It emits high-frequency sound waves, which are refracted and reflected back to form a real image. It has strong penetrating power, and the transmitted image is very accurate. Even if there are obstacles, it can bypass them for exploration. It has good effects in surveying, tracking, and reconnaissance. For example, if you want to survey the terrain or situation at the bottom of the water or lake, you can use this spell. ReadМ"

The audience below heard Anduin explaining with some strange words, completely unable to understand what he meant, only feeling that it seemed very powerful. If they asked others to clarify, they would appear uncultured, so they had to pretend to understand and listen with a straight face.

Anduin paused and then said, "Of course, many problems occurred when this spell was first developed. This spell has two parts: emitting and receiving. Currently, the emitting spell can be cast directly with a wand, but receiving is a bit more troublesome and requires a magical item made in conjunction with alchemy."

With that, he took out a large mirror with a diameter of one meter from the space bag on his body. This was something he had made temporarily some time ago. The materials were not very good, and the spell duration was only about a year, but it was more than enough for demonstration purposes.

Anduin manipulated his magic to make the mirror float in the air, facing the audience, and then waved his wand to cast the Echo Charm.

As the spell was cast, another scene quickly appeared on the mirror. It was the same scene inside the club room, but the mirror was completely composed of black and white lines. After adjusting it with magic, the scene in the mirror began to change, up and down, left and right, forward and backward. As the viewpoint was adjusted, the perspective in the picture also began to move. In this mirror, every corner of the room could be observed.

Then Anduin opened the window of the room and continued to cast the Echo Charm. Soon the outdoor scene was also slowly presented in the mirror, of course, all composed of lines, just like taking pictures with a drone close to the walls and the ground. Although the image quality was worse than black and white video, it could clearly present the external image, including trees, walls, stone pillars, etc.

Everyone in the room crowded in front of the mirror, carefully watching Anduin's demonstration, including Professor Flitwick.

"It's truly amazing, Anduin. This new spell is even more amazing than I imagined. You have to work harder and try to translate the spell's incantation as soon as possible. Otherwise, many wizards who are interested in this will not be able to cast it," Professor Flitwick praised without reservation.

Seeing the dazzling scene, Oriana was also secretly surprised at this time. Such a magical spell was actually real, and the effect was even better than she imagined, which made her couldn't help but take another look at Anduin.

But Anduin still had a calm expression, and just nodded modestly to Professor Flitwick.

After witnessing such a wonderful spell demonstration, the surrounding people enthusiastically offered their applause. At this time, they were truly conquered by Anduin's talent.

Everyone discussed the Echo Charm with great interest for a long time, and Anduin also answered everyone's questions very modestly. He liked the atmosphere in the Spell Club very much. There was no infighting, only an infinite love for knowledge and a serious and rigorous research attitude.

This academic discussion lasted for a long time without anyone realizing it, until Professor Flitwick called a stop, interrupting everyone's lingering thoughts. After all, it was already curfew time, and if they continued to stay, it would be bad if they were discovered.

After reluctantly saying goodbye to everyone, Oriana was still preparing to strike up a conversation with Anduin, but when she turned her head, he was gone, leaving her unable to say a word to this 'acquaintance' all night.

"As expected, he's a rude guy." Seeing herself as an outsider, Oriana pouted angrily and turned to leave.

On the other side, Anduin returned to the Slytherin dormitory and was preparing to do his homework for the night when the door was rudely knocked open.

Bang! Bang! Bang! "Open the door, hurry up!"

Along with the knocking, there was also a loud urging sound.

Oh? Are they starting to act up so soon, or are they rushing to die? Anduin thought for a moment, and then he had a bottom line in his heart, so he tidied up his clothes, waved his hand, and the door lock was unlocked.

Bang!

With another loud noise, Wilkes kicked the door open and strode arrogantly into Anduin's room. After looking around, he saw that Anduin was leisurely sitting at his desk reading a book, not even looking at him, and a burst of anger rose in his heart.

"Why are you so slow? Today is the first dormitory inspection by the committee. You, a stinky Muggle, are not honest at all. I advise you to be sensible and hand over the Muggle items on your body and in your room, otherwise..."

"Otherwise, you want to fight me, right?" Anduin interrupted Wilkes' words, raised his head, and glanced at him contemptuously.

Wilkes was interrupted, and his face turned pale. At the same time, he heard Anduin's provocative words, and couldn't help but recall what happened last school year. He hated him so much that his teeth itched, but he didn't dare to directly turn his face and fight here. First, fighting in the common room would definitely alarm Dean Snape, and he wouldn't have a good end. Second, he found that he seemed unable to beat Anduin.

Thinking of this, Wilkes put on a straight face, looked at Anduin seriously, and said, "This is the work of the Slytherin Pure Committee. Don't obstruct official business. Cooperate honestly, and we won't do anything to you. Stand up quickly and let us search you. If we find any contraband on you, you'll be the one who suffers first."

"Search me? Interesting. What if I say I don't agree? Your so-called committee hasn't been recognized by me," Anduin couldn't possibly let these guys touch him. There were quite a few things in his space bag that couldn't be seen.

"Hmph, you don't even follow the rules of Slytherin, and you dare to talk back." Travers, who was following beside him, stepped forward and glared at Anduin. "The Pure Committee is the common choice of Slytherin Academy. It's not something you can point fingers at."

Wilkes also nodded and said, "That's right. Since you are in Slytherin Academy, you must abide by the rules of Slytherin."

After listening to the two people's words, Anduin actually squinted his eyes and smiled. He smiled as he got up and walked towards the two of them. When Wilkes and Travers saw Anduin approaching, they were so scared that they took two steps back, but then they recalled that they were here representing Slytherin, so they had to stick out their chests and meet him.
