Lupin introduced the storage room to the students:

"If anything broken in the school, things that cannot be completely repaired will be piled up here."

He picked up a small short stick at his hand, "It's like this oak arrow 79, it's the first flying broom to be made."

The hand Cedric took away was quite complete, and the small piece in his hand was more abstract.

You can recognize it at a glance, either you have rich knowledge of brooms or you often come to explore during school.

Lupin briefly talked about the history here and asked the students to take a look around.

The accumulated debris is not only dirty, but most of them are useless waste.

"Okay, come back!"

The students gathered in front of him.

“Some places like this maze always hide invisible dangers.

So who can tell me what kind of danger will it encounter?"

Hermione quickly raised her little hand, "Professor, the environment here is very suitable for setting traps, and it is also the place where some magical creatures like to live the most."

"What are the more common magic creatures?"

She thought for a moment,

"There are Boggots, ghouls, foxes, red hats..."

Lupin nodded with satisfaction and added 2 points to Gryffindor Academy.

He turned his head and looked behind the dimly lit person, "Yes, as everyone guessed, there is one of the things Hermione just said.

So, does anyone want to guess what it will be?"

Vincent was the first to raise his hand, "Red Hat."

Needless to say, the ghoul and the fox can be cleaned up with bare hands, and it is not dangerous at all.

The remaining few are not difficult, so the closest answer is the XXXX level Red Hat.

"Congratulations, Vincent, you guessed it right."

The Red Hat is a difficult little creature that looks like a goblin and lives mainly in the Nordic region.

He has a big head and a small body, and his body is the same as a dwarf.

Usually lurking in blood-stained places such as castle dungeons, battlefield trenches, etc., waiting patiently for those who are lost to come.

When night falls, they will try to kill people with big sticks.

Although there are records of killing wizards, they can be driven away by using simple spells.

Lupin's wand lit up blue light,

"Red Hats are not very aggressive in themselves, but their lurking ability is very strong, and it is difficult for adult wizards to find them."

His wand pointed to the dim corners that could not be illuminated by the ceiling light ball,

"The scope of the exoteric spells is too small, and it was too late to find them."

There are a lot of waste here, which is very suitable for lurking and hiding.

However, Lupin's courage to bring students here to class must be full of confidence in his abilities.

"There are many spells that can be found in Red Hat. Today I want to teach you a more practical one."

Lupin smiled at the students, then looked back at the dark corner where the wand was pointing,

"The trace appears-"

The blue light at the tip of the staff flew over like a pulling arrow.

It seemed to be without substance, and disappeared after passing through a ragged old wardrobe.

The crack in the door of the wardrobe was glowing, and something should have been lit inside.

"Sher—" It seemed like a faint sound of tearing the clothes.

Lupin put away his wand and faced the students.

"I've marked one of the red hats, and no matter what it wants to do, the tracking spell will reveal where it goes."

The spell itself is not difficult, mainly because it requires strong control power to automatically retrieve and mark objects.

The shabby wardrobe made a clanging sound, and the conspicuous blue light ball ran around after it came out, as if looking for a better place to hide.

An invisible enemy is far more dangerous than a visible enemy.

As long as the Red Hat is exposed, it is not even difficult to find the ghouls and foxes.

“Who wants to try it?”

"I!" Vincent stood in front.

Lupin nodded slightly and signaled him to come over.

"The tracking spell allows a specific object to keep glowing. If you are not sure if there is any danger ahead, you can use it to search..."

After theory, it is practical.

Vincent raised his wand and recited the spell: "The trace appears-"

After the blue light shot out, vaguely felt 4 strange positions.

One of them ran around, probably the Red Hat marked by Lupin.

It can shape the control power of various alchemy props, and easily let the spell turn in the air.

It passed through a rusty iron door and finally disappeared into the darkness.

"Vincent!" Lupin raised his hand and pointed at the light behind the iron door.

"The second red hat was hidden there, and their danger was reduced a lot."

There are 4 in total, of course, all of them need to be found.

"Harry, would you give it a try?"

Lupin's name made Harry feel helpless.

After encouragement from Hermione and Ron, he stepped forward and raised his wand and recited a spell.

The tracking spell went around for a long time, then walked through a large broken mirror to reveal the position of the third red hat.

"You succeeded!" Ron acted even more excited than Harry, "I knew you could do it!"

The last one belongs to Hermione.

Her tracking spell flew to the ceiling, then passed through a rusty iron shelf in a very small arc.

"You are all great!" Lupin added 6 points to Gryffindor College with a smile.

"Okay, now I'll teach you to remove the spell."

The marks on his body disappeared, and the four red hats quickly hid again.

"Hannah, it's your place... Justin, come here...relax, Ernie, you are next..."

Just like when dealing with Boggart yesterday, the pace of the class is getting faster and faster, and every student has the opportunity to cast a tracking spell.

Of course, success will lead to failure.

But even Neville, who failed seven times, was not discouraged. The eighth time was just marked as a red hat trying to transfer his position.

With 5 minutes left before get out of class is over, all students are marked as successful.

Lupin had a bright smile on his face, adding 2 points to each of them.

"I won't assign homework today. After you go back, you will think carefully about what method to use to defeat the Red Hat."

The next black magic defense class is probably a practical class, which is about facing these Red Hats lurking and waiting for an opportunity to attack.

It's not boring at all, and the students are particularly looking forward to next week's class.

"Of course you have to use the coma curse!" Semo, who walked out of the storage room, suddenly pulled out his wand.

"Wait, I will definitely beat them all!"

This posture was quite sensible, and Dean next to him couldn't help but gesture to him.

As the quarrels were making an appointment to go to the activity room to practice.

Vincent, who had quietly finished his arithmetic divination class with the time converter, just came back and was surrounded by the little lions.

The parties are no longer important, and they don’t want to be embarrassed in practical classes.

"No problem, I'm fine on the weekend."

Soon, the Badgers and the Kitty Hawks joined in.
