Harry Potter: A Certain Ancient Rune Professor of Hogwarts (TL)

“First is a golem, since you all know about it, let’s quickly skim over this part.”

Felix moved his finger, and the golem on the table quickly moved, making all kinds of incredible movements under his control, and finally, ending with the golem releasing a fireball.

The young wizards looked at Felix blankly, and he smiled softly: “After the lesson, I’ll give one to each of you, no limits of any kind, and I hope this will become a Hogwarts tradition. Until next Tuesday, you can all have fun with the golem duels.”

Hermione’s eyes were fixed on the golem with the ice blue hair, and she saw the same blazing sight of the Slytherin girl whose last name is ” Greengrass”.

She pursed her lips, she would never give in!

She had been looking forward to it for a whole year.

The brown-haired girl opposite returned a similar look, and they both realized: the war had begun.

“Next, a collection of seven pocket Sneakoscopes.”

Felix walked from one side of the podium to the other, his left hand ran across the table, his ring bloomed with a hazy luminescence, and a row of Sneakoscope appeared on the table, as the young wizard stretched their necks to look hard.

“What you see here on the table is seven different kinds of Sneakoscopes. Now, to get you all involved, I have to ask: what is Sneakoscope?”

Hermione raised her hand, but Felix deliberately named Draco Malfoy for balance.

Draco stood up and said, “That’s a detector, used to alert us. My father says that the ones sold on the market are all junks, and my family’s Sneakoscope are specially customized.”

Felix glanced at him: “This represents only a minority’s view … or let me say that in the eighteenth century, the wizard Edgar Stroulger invented the prototype of the Sneakoscope, which was a dark magic detector shaped much like the common gyroscope shape nowadays. But actually magic items with similar effects date back thousands of years ago, although they weren’t called such at the time …

If we look at it from a modern perspective, we can think of Sneakoscope as a generic term for a type of detection and alarm device.

By modern times it is more minutely divided, and numerous spin-off versions of this item have been born – for example, the Probity Probe of the Gringotts, which is entirely deviated from its original design and looks like a long, thin golden antenna.

Or, the Secrecy Sensor, which can detect concealment or lies.

In the Sneakoscope we have seen so far, the function is basically limited to discovering suspicious characters, or detecting some dark magic.

But in fact …

It can do much more.

For example, warning against specific magic.

Against a specific behaviour.

Or even, for a specific bloodline, to the point … a certain person.”

Felix’s words were astonishing and completely turned the young wizards’ perception of the Sneakoscope upside down.

Most of the Slytherin students were sceptical, which went against what they had been taught since childhood.

But some people were convinced by Felix’s words –

For example, Ron is not averse of owning a Sneakoscope against a Malfoy, think about it, as long as he is 100 feet closer to him, he will get the message, he can hide in the bushes, or behind the gate post of the yard, waiting for an opportunity to give Malfoy a vile curse.

For that, he would give his entire year’s pocket money, and if he could make it himself, well, it would be even better.

“So, Professor, if I hate someone, I can make a type of Sneakoscope that is aimed at them?”

Ron blurted out, looking unabashedly at Draco Malfoy.

Draco’s expression turned dangerous as he narrowed his eyes and said, “Weasley, you could probably put a Sneakoscope in your house … for thieving rats, and your mother wouldn’t be crying out in sadness if there is a coin missing again, would she?”

“Malfoy, you wicked breed …”

“Okay, don’t quarrel. Or else fifty points each, plus three weeks of detention.” Felix said speechlessly, he hadn’t realized before that Malfoy’s mocking skills were so strong.

“As for Weasley’s previous question, the answer is I can do it, as for you guys, forget about it …”

“Might as well work on your sharp eyes.”

Professor Hap’s words made everyone feel helpless and listening to his description, the young wizards did have thoughts similar to Ron’s, mind you everyone has one or two annoying people.

Neville’s thoughts, on the other hand, were more normal; he badly expected a special Sneakoscope to remind him not to lose things, but he feared he might lose it too – it’s not impossible, that’s how he lost his Remembrall last year.

Neville painstakingly wrote down ‘Lucky Star’ on a piece of parchment, the Gryffindor common room password, but he always had trouble remembering it, and for that reason, he wrote it down in places wherever he could see it whenever he had the time.

According to his idea, as long as he recorded the password in enough places, he would never have to worry about forgetting the password, even if he happened to get it right once or twice …

“Well, let’s take a look at these seven Sneakoscopes.” Felix casually waved his wand and let a fist-sized brown chestnut Sneakoscope on the podium float into midair.

“The first, the most common type, commercially sold one, at most the shape, has some variations. The effectiveness is average and easy to make mistakes. The advantage is that it is easy and cheap to make.”

“But when camping in the wilderness you can use it to defend against dangerous creatures, it is barely enough for that.”

“The second, similar to the Probity Probe, can find the hidden spell on the wizard.”

“The third, for dark magic, my kind can detect seventeen of the more nefarious dark magic spells, including the Unforgivable Curses .”

He waved forth a heavy black glow, and the Sneakoscope immediately emitted a shrill alarm.

The young wizards on the stage looked at Felix in silence, the black light seemed to lock out any light. But he went on with no change in his face –

“The fourth, for a specific spell, is essentially a spin-off of the third Sneakoscope, but with a more flexible scope of application. This one in front of me is aimed at the disarming charm. Anyone wants to give it a try?”

Felix asked, pointing to a walnut-sized gray Sneakoscope.

All eyes turned towards Harry, who in recent rumours had single-handedly killed a squad of dementors with the disarming charm.

Draco didn’t believe the claims at all, and he firmly believed that all the various versions that have emerged so far are false, putting aside all the rhetoric: Potter encountered the dementor and fainted. This is the truth of the matter.

So he did the “Dementor” mouthing to Harry.

Harry is a bit nervous, but also a bit excited, he looked provocatively at Draco, waving his wand, silent, an arc of red light across the students of Slytherin’s side.

From the beginning, he did not concern himself with the spell, but rather stared at Draco.

To Harry’s satisfaction, his face turned pale.

As Harry’s charm launched, the gray Sneakoscope in midair twitched around, it kept flashing a red light and emitting a beeping sound.

Felix explained: “Do you see, a specific spell Sneakoscope, this is the way. It doesn’t look like anything, but if you placed this Sneakoscope for a regular ‘Unlocking Charm’ in the door, it might work as a pleasant surprise.”

“Be aware that a regular Sneakoscope can be shielded, and you never know if there is a prepared dark wizard standing outside your room.”

“The fifth one, for specific bloodlines. Just so you know, I won’t elaborate it.”

“The sixth, for specific people, the principle is simple, you only need a pinch of hair from the opposing party, like a polyjuice potion …”

“And the last one, for a specific feeling. I’m here with the ‘joy’ Sneakoscope, it’s interesting, isn’t it? If you’re going to tell a joke, it will help you understand the real emotions of your audience.”

“Anyone wants to try it?”
