In an empty room,

Hermione, dressed in a blue bodysuit and holding a wand in her hand, aimed earnestly in front of her.

The Dementor swam out of the glass room, roaring and lunging at Hermione.

Normal Dementors are about three meters tall, and the one in front of them has shrunk to the height of an ordinary adult.

It's not stunted growth, it's a rapid collapse of the body caused by not eating for a long time. This is a peculiar manifestation of the weakness of the Dementors.

The Dementor slid forward slowly, whirring in as a rancid hand grabbed Hermione.

In the eyes of the Dementors, Hermione was a beautiful delicacy, and like a thirsty traveler who found a spring in the middle of the desert.

Since its illegal captivity, it has been living a life of misery every day.

Every day, he was studied and studied by that boy, and he was destroyed by all kinds of magic every once in a while. Occasionally, if you don't use magic, you can switch to high-voltage electric shocks, high-speed water cutting, and splashing gasoline to simmer!

It's so cruel that the Dementors are outrageous!

If you don't do research, you can't rest, you'll be pulled out and be a sandbag for girls to practice the Patronus Charm!

Oh Merlin, when will this dark day come to an end?

In the beginning, the Dementors would curse and cry for help in their own language...... It's been a long time, and I'm hungry and even have no strength to speak.

It doesn't want to run away now, and it doesn't expect its companions to save it...... As a poor Dementor, you have to be pragmatic, it just wants to have a good meal!

Is there something wrong with that!

So the Dementors frantically pounced on Hermione.

"Divine Guard!" Hermione shouted.

White mist erupted, slightly blocking the speed of the big black robe.

Hermione struggled to remember those happy times with William, and with a press of her finger and a tap of her wand, the white mist grew thicker and thicker, eventually forming a bird.

The bird swirled happily in front of Hermione, spun around a few times, and in an instant shot straight into the Dementor's head.

The bird was so fast that it was impossible to avoid it, and the sliding Dementor was knocked to the ground on the spot...... It's fast, like an old man who touches porcelain.

William sat in the distance, closed the book in his hand, and couldn't help but say:

"Almost, Hermione, you've learned the Patronus Charm, don't torture it, look at the skinny kid."

"It's still far away, this Dementor is already very weak, and it has little effect on me."

Hermione panted, expertly took the potion from the table and drank it down.

She gasped a few times, looked at William with burning eyes, and said, "Come, let's fight." ”

"Not taking a break?" William frowned slightly, Hermione had been a little strange since saying goodbye to Fleur.

Looking at William's expression, Hermione knew what he was thinking, so she explained:

"I just found that I had a lot of shortcomings, and I continued to improve myself while school hadn't started yet."

"There's no need to put too much pressure on yourself, you're already very good among your peers."

"But it's far worse than Fleur...... At least I can't beat her. Hermione muttered discontentedly.

"She's two years older than you." William picked up the thermos cup next to him.

"So I have to redouble my efforts to close the gap between these two years, and I can't be compared to her." Hermione couldn't have been more serious.

"I must be able to beat her, and better beat you again, so that if you dare to ...... Hmph, I'm going to cast a curse on you! ”

William choked on a mouthful of water and said angrily: "A little conscience, okay?" ”

Hermione, smiling intoxicatingly, walked over and took William's cup, drinking all his water with not a drop left.

William stood up and pulled out his wand.

He decided to let Hermione, who has become more and more bold and spicy recently, see what it means to "come first with a little cold, and then stick out like a dragon".

Ten minutes later, Hermione was running out of magic and was too tired to stand up. William, on the other hand, acted like he was fine.

The two took a shower, changed into clean clothes, and lay down on the sofa in the living room.

"What are you going to do with that Dementor?" Hermione asked, leaning on William's shoulder.

"We're back in England, so we're on the safety sheet, will the Dementors come to the door?"

That's right, it's only one week left until school starts.

A week ago, they returned to London from a trip to France.

In order to continue Hermione's training, William brought Anne to Hermione's house for a few days, which was called "tutoring".

No one cared about them anyway, Lyanna was out for a while, and the lab was handed over to the hard-pressed graduate students.

Now it's time to manage and show your presence.

Roy and Elise have amassed a bunch of appointments and have been busy lately.

"I guess I won't find out." William said uncertainly.

His current research on Dementors was only early in the door.

Dementors can speak, and even communicate briefly with wizards.

I just don't know what kind of communication they use to communicate with each other. It can't be air transmission or electromagnetic wave induction.

But even if you are inducted by electromagnetic waves, you can't hand over the Dementors.

William's research revealed that the Dementor's ability to fly was not due to its ability to fly, but to rely on the black cloak.

The cloak is an innate item, like the fur of a magical beast.

So Dementors are, in a way, a lot like Invisible Beasts.

Invisible beasts can become invisible because of that layer of fur. Thanks to the special power of that layer of fur, it can be used to weave invisibility cloaks.

All William is thinking about now is stripping him of the Dementor's cloak and making it into a flying cloak!

This is the proper Doctor Strange's levitation cloak...... No, it's supposed to be Stark's levitation cloak!

If it could be done, the Dementors would probably go from being guarded to being the object of capture.

After all, there is no buying and selling, there is no killing.

Well, the Dementor can never be completely destroyed, it's a renewable resource!

Just as William was thinking, Hermione suddenly got up, put on the boy's slippers, and ran towards her room.

A moment later, the girl ran back with a box in her hand.

She sat cross-legged on the couch and opened the box, revealing seven sparkling gems.

"When you go to Diagon Alley later, do you want to put it all in the vault?" Hermione's eyes twinkled.

"Still no, I went back and checked and consulted Nicol and Dumbledore.

This gem is very similar to the lost Elven Diamond, and if it were in the vault, the elves would surely find it. William said helplessly.

Hermione thought about it for a moment, and then the chick pecked at the rice and nodded vigorously!

"Yes, the elves are greedy, and the vaults are not safe. Do you remember the summer vacation the year before last, when we encountered a mysterious person attacking the vault. ”

Hermione said melancholy, "So where to hide?" ”

"Where were you hiding?" William asked knowingly.

"Hidden under my bed!"

"You can still hide there." William laughed. "Underneath your bed, it's the safest place in the world."

Hermione nodded immediately and grinned, she thought the same.

The girl rolled her eyes and asked tentatively, "Is such a valuable thing really entrusted to me for safekeeping?" ”

"Of course." William couldn't hold back a smile, "You take good care of it, don't lose it, I'll give it to the girl in the future." ”

Hermione's face was shocked, aggrieved, and sad. In the end, I was crying.

She pushed the box and said scoundrelly, "...... Forget it, save it for yourself! ”

William took the box and said regretfully, "Since someone doesn't want it, forget it." Just give it to Hibiscus...... She should love it. ”

Hermione snatched the box again, hiding behind her like a baby.

William stared at Hermione's side face, at the dimple, stunned.

……

……

After spending more than an hour, the two left the safety sheet and appeared in Hermione's room.

Hermione was startled because she had locked the door to her room when she entered the security table.

I didn't expect there to be someone in the room now!

Then, at a glance, the two of them saw Annie lying on Hermione's bed!

Anne lay sideways on the bed, her head off the bed, hanging upside down.

She was holding a strange thick book in her hand, looking at it carefully, humming a song in her mouth, and her two thin legs with white flowers were still kicking around happily.

Hermione snorted...... A smell of malt in the room.

"Ahhh She screamed.

"Annie, you're lying on my bed eating again?!"

Hermione pounced.
