"First of all, the magic puppet. Since you all know it, let's quickly skip this part of the content."

Felix provoked his finger, and the magic puppet on the table quickly moved, making various incredible actions under his control. Finally, he ended with the magic puppet releasing a fireball.

The little wizards looked at Felix with a chuckle, and he chuckled: "After the course, I will send one by one, without any restrictions, and I hope this will become a tradition in Hogwarts. You can enjoy the magic puppet battle until next Tuesday."

Hermione's eyes were staring at the puppet with ice-blue hair, and she saw the same blazing sight, the Slytherin girl named "Greengrass".

She pursed her lips, and she would never give in!

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

The brown-haired girl opposite returned with the same look, and they all realized that the war had begun.

"Next, there are seven pocket-sized mirrors."

Felix walked from one side of the podium to the other side, and his left hand crossed the tabletop. The ring was filled with fluorescent light. A row of spectators appeared on the tabletop. The little wizard stretched his neck and looked around hard.

"What you see is seven kinds of spectators. Now, in order to make you feel a little involved, I want to ask: What is spectators?"

Hermione raised her hand, but Felix deliberately pointed Draco Malfoy's name to balance.

Draco stood up and said, "That's a detector used to call the police. My dad said that the market sells garbage, and our spectacles are specially customized."

Felix glanced at him: "This only represents the view of a few people... Let me say that in the eighteenth century, the wizard Edgar Straug invented the prototype of the spectator, which is a black magic detector, which looks very similar to the shape of a gyroscope that is common today. But in fact, magical objects with similar functions can be traced back thousands of years, although they were not called this name at that time...

If we look at the eyes of future visitors, we can think that the spectator is a general term for a type of detection and alarm supplies.

In modern times, many derivative magic items were born, such as the honest detector of Guling Pavilion. Its shape was completely separated from the original design and looked like a slender golden antenna;

Or, a secret probe, it can discover conspiracies or lies;

The functions of the look-up glasses we have seen are basically limited to discovering suspicious characters or detecting some black magic.

But in fact...

It can do more.

For example, warnings for specific magic;

To target a certain behavior;

Even, it is targeted at a specific bloodline, so that... a certain person."

Felix's words were amazing, completely subverting the little wizards' perception of the mirror.

Most of the students in Slytherin are skeptical, which is contrary to the education they received since childhood.

But some people believe in Felix's words

For example, Ron is not opposed to having a look-up mirror against Malfoy. Think about it, as long as he gets 100 feet closer to him, he will get news that he can hide in the grass or behind the gate post of the courtyard and wait for an opportunity to give Malfoy a curse.

For this, he was willing to pay a whole year of pocket money, and it would be even better if he could make it himself.

"Professor, so if I hate a person, can I make a look-up glass for him?"

Ron shouted, looking at Draco Malfoy without any concealment.

Draco's expression became dangerous, and he squinted his eyes and said, "Weasley, you might be able to put a glass at your house... to prevent mice. If a Nat is missing, your mother wouldn't cry sadly, right?"

"Malfoy, you bad guy..."

"Okay, don't make a noise. Otherwise, each deduct 50 points, plus three weeks of confinement." Felix said speechlessly. He had never noticed that Malfoy had such a strong foundation in ridicule.

"As for Weasley's previous question, the answer is that I can do it, as for you, don't think about it..."

"It's better to exercise your eyes smarter."

Professor Happ's words made everyone feel helpless. After listening to his description, the little wizards did have ideas similar to Ron. You should know that everyone has one or two people who hate them.

Neville's idea is relatively normal. He really hopes that a special spectacle can remind him not to lose it, but he is worried that he will lose the spectacle. This is not impossible. His memory ball from last school year was so missing.

Navi wrote the "Great Stars" on a piece of parchment in distress, which was the command of the Gryffindor Common Room, but he could never remember it, and for this, he would write the word anywhere he could see whenever he had time.

According to his idea, as long as he has enough places to record passwords, he will no longer have to worry about forgetting the password. Even if he takes his luck, he can still touch it once or twice...

"Okay, let's take a look at these seven kinds of spectators." Felix waved his wand casually, allowing a brown chestnut spectator with a fist-sized fur to float into the air on the podium.

"The first type, the most common type, is the one sold on the market, at most it has some changes in appearance. It is not targeted, the effect is average, and it is easy to make mistakes. The advantage is that it is easy to make and the price is cheap."

"But it's barely enough to use it to defend against dangerous creatures when camping in the wild."

"The second type, similar to an honest detector, can discover the curse hidden in the wizard."

"The third type is for black magic. I can find seventeen more evil black magic, including the unforgivable spell."

He shook out a heavy black light, and the spectator immediately made a sharp alarm sound.

The little wizards in the audience looked at Felix in a silent state. The black light seemed to be able to lock in any light. But he continued to talk as usual.

"The fourth type, targeting a specific spell, is essentially a derivative of the third type of spectator, but the scope of application is more flexible. The one in front of me is targeting a disarming spell. Does anyone want to try it?"

Felix asked, pointing at a grey spectator the size of a walnut.

Everyone looked at Harry. In recent rumors, he killed a team of dementors by using the disarming curse alone.

Draco didn't believe this rhetoric at all. He firmly believed that all the versions that appeared at present were fake, putting aside all the modified remarks: Porter met the dementor and then fainted. This is the truth of the matter.

So he made a "dementor" lip shaped towards Harry.

Harry was a little nervous and excited. He looked at Draco provocatively and waved his wand casually. A curved red light passed by the Slytherin student seat.

From beginning to end, he did not pay attention to his spell, but stared at Draco.

To Harry's satisfaction, his face turned pale.

As Harry's spell was activated, the gray spectator in the air began to sway, and red light kept flashing, making waves of beeping.

Felix explained: "Did you see it? This is the case with a viewing mirror for a specific spell. It doesn't seem useful, but if you put a viewing mirror for a regular "lock-opening spell" in the room, it might have an unexpected effect."

"You know, ordinary spectators can be blocked, and you will never know if the one standing outside your room is a prepared black wizard."

"The fifth type is for specific bloodlines. Just you know it, I won't talk about it."

"The sixth type, for specific people, the principle is very simple. You only need a pair of hair from the other party, just like a compound decoction..."

"And the last one is to target specific feelings. I am a 'joy' look-up glass, which is very interesting, right? If you plan to tell a joke, it will help you understand the true emotions of your audience."
