Mastering Lightning from Hogwarts

“I see. Well… Head Boy, would you be willing to personally guide us in casting the spell? Even just demonstrating it once would be great, I’d really like to see it.” Mona, who had previously been praised by Anduin, also crowded around him and interjected.

“With your skill level, you should be able to use this self-defense spell proficiently, right?” Anduin knew Mona's level; although she wasn't as all-around excellent as Ibo and Jenny, with all subjects scoring E or above, she was very good in most subjects.

“That's the thing, Head Boy. I do understand the principle of this spell, but because the Defense Against the Dark Arts class rarely has practical exercises, although I can cast the spell well enough to pass the exams, I can't use it proficiently.” Mona was usually quiet, but she mustered her courage when facing Anduin, and said with a blush.

“I see.” Anduin pondered for a moment. “After the evening self-study session in three days, it’s the Defense Against the Dark Arts study group's remedial lesson. Although you aren't on the remedial list, if you want to stay and listen, I’ll personally demonstrate it for you.”

“Tha… thank you, Head Boy.” Mona and the several small wizards next to her stammered their thanks before slowly turning and leaving.

Anduin's affability during the evening self-study session slightly diluted the tense atmosphere of the academy. And when the young wizards discovered that only studying could allow them to relax a little, what would they do?

They would definitely study like crazy! Now their tense nerves could only be soothed by studying, which in turn made their enthusiasm for learning even more intense.

And as Anduin announced the end of self-study time, many of the young wizards even showed reluctance when leaving the stone hall, because after going out the next day, they would have to be on edge all the time.

……

The next day, the little snakes, whose doors were knocked on again by the prefects, discovered that Anduin had disappeared again.

This time they wouldn't be fooled. Although they didn't know how Anduin managed to observe so many people at the same time, they now understood in their hearts that this Head Boy was probably hiding somewhere, watching them.

These prefects were even more on edge, especially Joey. Half of their fourth-year students had made mistakes yesterday and were punished.

At the same time, Joey also woke up after being educated by Anduin, realizing that not strictly enforcing discipline would harm the students around him. Today, his inspections were incredibly strict.

As for Lumen, who had tragically endured three punishments last night, although his body was sore and his arms felt like they were filled with lead, he still stubbornly did his best to keep his personal belongings in order.

“Mona.” After inspecting everyone's personal belongings, Joey looked at the female student somewhat embarrassedly. He hadn't spoken to her more than a few times since entering school.

“What is it?” Mona's expression was also a little stiff when she was called out.

“I… you also know that I'm not very bright, and after yesterday's reminder from the Head Boy, I know that you are more careful and remember the rules more clearly, so I would like to ask you to help me… or rather, guide me on how to prevent everyone from making mistakes, okay?” Joey looked at the girl in front of him with some trepidation.

“Um, okay.” Mona was a little unaccustomed to Joey's sudden humility, but she kindly nodded in agreement.

“Good heavens, Master, these two guys' conversation is too stiff. Do they usually talk like this?” A huge dog head leaned close to Anduin, sniffed the steaming, rich coffee in his hand, and then stared intently at the mirror in front of him.

This was Hogg, who looked like a dog but was actually a wolf. At this moment, he was leisurely staying in the dormitory with Anduin.

Anduin elegantly crossed his legs, drinking coffee, while Hogg was next to him, nimbly fiddling with the equipment in front of him.

The device in front of Hogg looked like a large dressing table, but the upper part was different from the large mirror of an ordinary dressing table. Instead, it had dozens of small mirrors of uniform size distributed in an orderly manner.

Each mirror showed a different image, and these images contained one to several young wizards, who were precisely the Slytherin little snakes.

It turned out that Anduin wasn't following them invisibly every step of the way like those young wizards thought. After all, Anduin was also a person and couldn't be in several places at the same time to monitor others.

He relied on the device in front of him, which could tentatively be called a magical surveillance device.

This surveillance device was actually completed at the end of the last school year. At that time, he was preparing to investigate the details of these young wizards in the academy. After personally tracking them with the Disillusionment Charm for a few weeks, he found that the efficiency was too slow, so he made this thing.

It actually used the principle of the Floo Network and his Raven Messenger Spell to share vision. When Anduin wanted to activate this monitor, he would release dozens of small ravens, cast the Disillusionment Charm on them, and then connect the shared vision to the mirrors.

This way, he could monitor these little snakes closely at any time, and it was very flexible. As long as it was within Hogwarts, he could share the vision in real time.

At the same time, he didn't have to run around particularly laboriously, and he also had time to do some of his own things.

The most excited about this matter was Hogg beside him. He was brought directly to Anduin's dormitory by Kiki via Side-Along Apparition the day before yesterday.

Although he had also stayed in Hogwarts last school year, he had never been inside the castle. This sudden arrival at a new place made him extremely excited.

And who knew that as soon as he arrived in Anduin's dormitory, he would discover this magical thing. This was much more interesting than gnawing on table legs.

So Hogg volunteered to supervise these young wizards for Anduin. It just so happened that Anduin also felt that he couldn't keep up with watching so many monitors alone, so he let him join in.

Then Anduin witnessed what a true surveillance person, no, surveillance dog, was.

Hogg seemed to be able to merge with the monitor in front of him. Not only could he observe different mirrors with his left and right eyes at the same time, but he could also very delicately capture fleeting images of violations.

You should know that yesterday Anduin caught almost all the young wizards who had violated the rules, and he also clearly pointed out where they had violated the rules. None of the people he pointed out complained; they all admitted their mistakes on the spot and accepted the punishment.

Such an exaggerated monitoring accuracy rate further deterred those young wizards who violated the rules. It was simply terrifying.

But all of this was actually done by Hogg. After Anduin confirmed yesterday that he wasn't as good as this dog at watching the monitors, he ran to the barbecue and cat-petting area next to the Forbidden Forest cabin in the afternoon.

At this moment, Hogg was squinting his small eyes and staring at the monitoring mirror, concentrating intently.

And when you thought he was only staring in one direction at this time, his eyeballs would dart around at a very outrageous speed.

Then he grinned, coldly smiled, and nimbly grabbed a quill with his dog paw, meticulously recording it on a piece of parchment.
