A certain Hogwarts professor of runes

Chapter 191 Seven Types of Peeping Mirrors

"First, let's talk about magical golems. Since you already know something about them, let's skip this part quickly."

Felix flicked his fingers, and the magical puppet on the table came to life, performing all sorts of unbelievable actions under his control. Finally, the magical puppet released a fireball to end the event.

The young wizards looked at Felix expectantly, and he chuckled softly. "After the course ends, I'll give each of you one, without any restrictions. I hope this will become a Hogwarts tradition. You can enjoy the fun of magical puppet battles until next Tuesday."

Hermione's eyes were fixed on the puppet with ice-blue hair, but she met the same intense gaze from the Slytherin girl named "Greengrass".

She pursed her lips, determined not to back down!

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

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

"Next, we will introduce seven types of miniature spyoscopes."

Felix walked from one side of the podium to the other, his left hand sweeping across the table. A ring glowed faintly, revealing a row of viewing mirrors on the table. The young wizard craned his neck, straining to see.

"What you've seen so far are seven types of spyglasses. Now, to give you some sense of participation, I'm going to ask: What is a spyglass?"

Hermione raised her hand, but Felix, to balance things out, specifically called out Draco Malfoy's name.

Draco stood up and said, "It's a detector, used to sound an alarm. My dad said the ones sold on the market are all junk; our spyglasses are custom-made."

Felix glanced at him. "That only represents the opinion of a minority... Let me explain. In the 18th century, the wizard Edgar Strauger invented the prototype of the spyglass, a kind of black magic detector, shaped much like the spinning top we use today. But magical items with similar functions can actually be traced back thousands of years, although they weren't called that back then..."

From today's perspective, we can consider a spy scope to be a general term for a class of detection and alarm devices.

In modern times, the categories have become more detailed, and many derivative magical items have been created—for example, Gringotts' Honesty Detector, whose shape has completely deviated from the original design and looks like a thin, long golden antenna.

Or, a detection device, capable of uncovering conspiracies or lies;

The spyglasses we see now are basically limited to discovering suspicious people or detecting some kind of black magic.

But actually...

It can do more.

For example, warnings for specific types of magic;

Targeting a specific behavior;

It's even targeted at specific bloodlines, to the point that... a particular individual.

Felix's words were astonishing, completely overturning the young wizards' understanding of the Spyglass.

Most of the Slytherin students were skeptical, which contradicted their upbringing.

But some people firmly believed Felix's words—

For example, Ron wouldn't mind having a spyglass to target Malfoy. Just imagine, if Malfoy gets within 100 feet of him, he'll get the message. He can hide in the bushes or behind a gatepost in the yard and wait for the right moment to deliver a curse to Malfoy.

He was willing to give up a whole year's allowance for this, and it would be even better if he could make one himself.

"Professor, so you're saying that if I hate someone, I can make a spyglass specifically for them?"

Ron spoke loudly, looking unabashedly at Draco Malfoy.

Draco's expression turned dangerous. He narrowed his eyes and said, "Weasley, maybe you could put a spyglass in your house... to keep out mice. Your mother wouldn't cry her eyes out if one Knut was missing, would she?"

"Malfoy, you wicked seed..."

"Alright, stop arguing. Otherwise, we'll each lose fifty points, plus three weeks of confinement," Felix said speechlessly. He hadn't realized before how good Malfoy's sarcasm was.

"As for Weasley's question earlier, the answer is that I can do it, but you can forget about it..."

"It would be better to train your eyes to be more alert."

Professor Hyp's words left everyone feeling helpless. After hearing his description, the young wizards did indeed have similar thoughts to Ron's. After all, everyone has one or two annoying guys.

Neville's thoughts were more normal. He really hoped for a special viewing mirror to remind him not to be forgetful, but he was worried that he would lose the viewing mirror—which was not impossible, since his memory ball had disappeared in the same way last year.

Neville, frustrated, wrote "Good Fortune" on a piece of parchment. It was the password to the Gryffindor common room, but he could never remember it, so he would write the word down wherever he could find it whenever he had a spare moment.

In his mind, as long as he wrote down the passwords in enough places, he would never have to worry about forgetting them again, and even if he got them right by chance, he could get them right once or twice...

"Alright, let's take a look at these seven types of spyglasses." Felix casually waved his wand, causing a fist-sized brown chestnut wood spyglass on the podium to float into the air.

"The first type, the most common type, is what's sold on the market, with only slight variations in appearance. It's not very targeted, the effect is so-so, and it's easy to make mistakes. The advantage is that it's easy to make and inexpensive."

"It's barely enough to use as a temporary defense against dangerous creatures when camping in the wild."

"The second type is similar to an honesty detector, which can detect hidden spells on a wizard."

"The third type targets dark magic. My method can detect seventeen types of particularly vile dark magic, including the Unforgivable Curse."

He unleashed a heavy black light, and the spy scope immediately emitted a sharp alarm.

The young wizards below the stage stared at Felix in utter silence, the black light seemingly capable of blocking out all other light. But he continued speaking with an unperturbed expression—

"The fourth type is for specific spells, essentially a derivative of the third type of spying, but with a more flexible application. The one in front of me is a disarming spell. Anyone want to try it?"

Felix pointed to a gray scope the size of a walnut and asked.

All eyes turned to Harry, who, according to recent rumors, had single-handedly killed a group of Dementors with a Disarming Charm.

Draco didn't believe this story at all. He firmly believed that all the versions that had appeared were fake, setting aside the embellishments: Potter encountered a Dementor and then fainted. That was the truth.

So he mouthed "Dementor" to Harry.

Harry was a little nervous and excited. He looked at Draco defiantly, casually waved his wand, and silently, an arc of red light swept past the Slytherin students' seats.

Throughout the entire process, he paid no attention to his own incantation, but instead stared at Draco.

To Harry's delight, his face turned pale.

As Harry cast the spell, the grey peephole in mid-air began to spin rapidly, flashing red light and emitting a buzzing sound.

Felix explained, "You see, this is what a spyglass for specific spells looks like. It doesn't seem very useful, but if you put a spyglass in a room that targets regular 'unlocking spells,' it might have a surprising effect."

"You should know that ordinary spyglasses can be blocked. You never know if the person standing outside your room is a prepared dark wizard."

"The fifth type targets specific bloodlines. You just need to know about it; I won't go into detail."

"The sixth method is for specific individuals. The principle is simple: you only need a tuft of their hair, like a compound decoction..."

"And the last one is for specific feelings. Here I'm using the 'joy' lens, isn't that interesting? If you're going to tell a joke, it will help you understand the true emotions of your audience."

Anyone want to give it a try?
