Mastering Lightning from Hogwarts

Charles watched Anduin clean up the scene, didn't think much of it, ran into the house and poured himself a large glass of water, drinking it all down, then asked curiously: "How's your experiment going? I seem to remember you saying something about a sonic wave magic experiment last time. Read"

"It's made some progress, but now there are new problems. I still need to find a way to isolate sound waves. In short, it's very troublesome," Anduin replied, pondering the solution.

"Isolate sound? Wouldn't the 'Quieting Charm' or 'Silencing Charm' work?" Charles asked.

"Probably not. Sound waves and sound are different. It's not just about not being able to hear it," Anduin replied helplessly.

"So complicated? Sound waves? I've never heard of them, but I've heard of water waves. If sound waves could be calmed by the Wave-Vanishing Spell like water waves," Charles said casually while drinking water.

"Wait, Charles, what did you just say?" Anduin suddenly raised his head, staring intently at Charles.

"What did I say? Water waves," Charles said.

"Not that, what spell did you just say could calm water waves?" Anduin confirmed.

"Are you talking about the 'Wave-Vanishing Spell'?" Charles said uncertainly. →

"Yes, that's it. Is there really such a spell that can calm water waves?" Anduin asked.

"Ah, I heard a senior bragging about it. It's Granda Chitoke, a senior from our house. She said she encountered waves while traveling on the Aegean Sea, and a wizard traveling with her used this spell to calm the waves. She also learned this spell from that wizard," Charles replied, seeing Anduin staring at him wide-eyed, telling him everything he knew.

"Can I ask that senior to teach me? This is very important for my experiment," Anduin asked excitedly, hearing that a student at the school knew this spell.

"Her? She's already a 7th year student now. It seems like she ran off to intern because she applied for a job at Wizarding Wireless Network," Charles replied, recalling.

"What? Is she coming back to school? I remember 7th years have to take a final magic exam," Anduin asked.

"That doesn't seem to be mandatory. I'll go back and ask the others in the Mahjong Club. Another senior is quite familiar with her," Charles replied.

"Mahjong Club? What's that? Is there such a club?" Anduin seemed to have heard something incredible.

Charles put his hands on his hips and laughed: "Of course. Vivian and I created that club. You're always mysterious and don't walk around the castle, so you don't know. Our club now has more than a dozen members."

"What do you usually do in this club? Just play mahjong?" Anduin asked curiously, feeling that this club appeared out of nowhere.

"Yeah. You lent us a mahjong set before, and then didn't you give Vivian and me a set each after Christmas? We take these mahjong sets and take turns playing cards in our respective houses when we have nothing to do. Later, more people liked it, so a club was naturally formed. You know, there's also the Wizarding Chess Club, Gobstones Club, Exploding Snap Club, etc. at Hogwarts. Now our Mahjong Club has no fewer people than other game clubs, and it's also a large club in the school," Charles said with a smile, knowing that he was one of the founders of this club.

Such a thing existed? It seemed that he had been so immersed in research that he hadn't paid attention to things in Hogwarts Castle. Anduin rarely even looked at the school bulletin board. He was the one who taught these two people to play mahjong, but he never touched the tiles again.

Charles was very proud of the established Mahjong Club and wanted to pull Anduin into the club, but Anduin didn't have the mood for entertainment right now and refused him, only instructing Charles to help inquire about Senior Granda Chitoke's situation.

…

"So, that senior will only be back to the school next week?" Two days later, Anduin looked at Charles, who had come to train, and asked about the matter he had instructed earlier.

"Yes, it seems that senior's internship results are very good. It is said that she may become a broadcaster for Wizarding Wireless Network in the future," Charles replied, recalling the news he had gathered from senior students.

Since the failed experiment two days ago, Anduin had not dared to cast the 'Subsonic Wave Charm' casually, but only used the rune plate to optimize the structure of the spell a few times, but it was completely unclear what the effect would be.

In his vision, water waves and sound waves are both waves. The Wave-Vanishing Spell can dispel water waves, so theoretically it should also have an effect on sound waves. Even if it's not completely useful, it should give him some inspiration, so he seemed so anxious.

"Okay, then I'll leave it to you, Charles," Anduin knew that things couldn't be rushed.

"Don't worry, I'll go find her as soon as that senior returns to school," Charles assured Anduin.

"Okay, thank you, Charles," Anduin said, then added: "Seeing that you can adapt to this intensity of training recently, we can officially start special training."

"What, wasn't that training before special training?" Charles was taken aback and stared at Anduin seriously.

"That was just adaptive training, like warming up before exercise. I was afraid you couldn't handle high-intensity training from the beginning," Anduin explained indifferently.

"Hiss!" Charles gasped. Was this just a warm-up? He had been tortured to the point of wanting to die by Anduin's training for the past month. At the beginning, he couldn't even keep up with the running, and the afternoon's spells and delayed training were even more tiring. He really couldn't imagine what kind of cruel training there could be.

Seeing Charles's slightly resistant expression, Anduin said seriously: "Okay, what's the point of suffering a little if you want to improve?"

Immediately afterwards, Anduin pulled Charles to a flat ground outside and said: "Let's proceed little by little, step by step, so as not to affect your normal studies."

Charles naturally nodded frantically in agreement.

"Next is the first subject, stance training, mainly including Horse Stance, Level Stance, Three-Body Stance, Hunyuan Stance, etc. I mainly teach you the Horse Stance. Watch my posture," Anduin demonstrated and explained to Charles.

"Stance training, what's that?" Charles looked at Anduin squatting with his legs apart, posing in a strange posture.
