The sickly iron fist beauty in Harry Potter

The bright light instantly made the Room of Requirement, which was originally shrouded in the glow of an oil lamp, brightly lit.

The three girls, who were used to the light of oil lamps, even found it a little dazzling.

But they soon got used to it and gathered in front of the dashboard, comparing all the data with Dolly.

Finally, it was confirmed that, at least in terms of power generation, there were no abnormalities in either voltage or output current.

The three girls hugged each other excitedly, as if they had already found hope of evolving from the Middle Ages to modern society.

The study time during the day is fine, and the conditions at Hogwarts are not bad either.

But the boring time to relax at night was too monotonous and boring, even for Hermione.

Now that we have electricity, three people can do a lot more things and use many electrical appliances to improve their lives.

"Don't be happy too soon."

Dolly reluctantly let go of Qiu Zhang and Hermione's waists at the same time, pouring a basin of cold water on the two girls.

Although the legendary electromagnetic shielding has not yet appeared, Dolly feels that this legend should not be groundless.

So then Dolly, Qiu Zhang and Hermione began to try whether the electrical appliances they brought could be used.

Soon the three of them came up with the answer.

All simple electrical appliances that do not require electronic signal transmission, such as hair dryers or electric kettles, can be used normally.

But any device that involved the transmission of electronic signals, such as game consoles, televisions and radios, became useless and started to make a constant rustling sound.

This is an unsatisfactory result.

What makes people happy is that Dolly's efforts over the past month have indeed been useful, but what makes people dissatisfied is that the entertainment equipment that is most irreplaceable when using spells is actually the most unusable.

Looking at the snow on the TV, the three of them sat on the ground in silence for a long time.

In the end, Qiu Zhang hugged Duoli's arm and said, "It's not bad actually. At least we can enjoy half of the modern life, right?"

Dolly was about to nod when Hermione said, "I think there might be a way to solve this problem."

Qiu Zhang and Dolly looked at Hermione in surprise. Hermione said, "What we suspect now is that some invisible interference is preventing the electronic equipment from functioning properly, right?"

"Then why don't we find a way to block this interference, or temporarily drive away the source of the interference?"

Qiu Zhang subconsciously said, "But we don't even know what it is..."

"That's what we should try and study, right? And this is exactly the area that has never been studied before."

Hermione laughed happily and said, "Absolutely. I don't believe any wizards have studied these things, because they must have rarely seen a TV."

Qiu Zhang had no way of refutation and could only nod.

But is studying this kind of thing beyond their scope?

Dolly looked at Hermione with interest and said, "Do you have any ideas, or are you planning to help me?"

The smile on Hermione's face disappeared instantly, because she was unlikely to spare much time to help Dolly solve this problem, as she still had to do her second final review.

So Hermione hesitated for a few seconds and said, "I can spare an hour every day to help you research and give you some advice, but you still have to do more things yourself."

Hermione was worried that Dolly would be disappointed, but she received a warm hug and sincere thanks from Dolly.

This made Hermione feel a little regretful, and she felt that she should spend more time with Dolly.

Studying is important, but Dolly is equally important!

But in the end, Hermione couldn't resist the temptation of getting the first place in the exam, and temporarily put Dolly and Dolly's affairs in second place.

"Do you have any ideas now, Hermione? Qiu Zhang, you can also use your brain. After all, you are one year older than us."

Dolly continued to preside over the meeting, and she was really interested in resolving the matter.

Although it was originally for entertainment, now that the environment has changed, Dolly feels that if she can really achieve electrical freedom in Hogwarts.

Then there will be many more practical ways to protect the safety of yourself and your friends, and even take control of this place in your own way.

For example, installing some cameras or something like that - we already have mature closed-circuit surveillance systems in this era, but they are still a bit clumsy compared to the networked surveillance systems of the future.

But as long as it works, Dolly is not picky.

Hermione thought for a moment and said, "According to our conclusion, this interference is like an electromagnetic wave - you should be able to understand electromagnetic waves, right?"

Seeing Dolly and Qiu Zhang both nodded, Hermione continued, "Although in the wizarding world, it's unlikely that electromagnetic waves will interfere with our electrical appliances, it should be something similar, such as what we temporarily call magic waves."

"It has properties similar to electromagnetic waves. It cannot be seen or touched, but it exists around us."

"It has no effect on our bodies, but it may have an impact on our spellcasting."

"Of course, these are just speculations. Let me get to the point."

Hermione simply took out a pen and paper and started writing: "We have a way to shield electromagnetic waves over there, so is there a similar method in the wizarding world?"

"Dolly, your silver shield can resist magic. Perhaps if more of the same material were made into protective cases, it would allow electrical appliances to function properly?"

"Of course I know this isn't very realistic. After all, your silver is too valuable, but perhaps we can try other materials, such as..."

While Hermione was pondering carefully, Qiu Zhang said, "Like dragon skin?"

Dolly and Hermione looked at Qiu Zhang in surprise, wondering why she would think that.

Qiu Zhang smiled slightly and said, "Isn't dragon skin the most commonly used method by wizards to block magic? Dragon leather gloves, even dragon leather clothes, and dragon leather earmuffs."

"We used it in Potions and Herbology."

Dolly and Hermione nodded immediately, thinking it made sense.

But then the question arises, where can they get the dragon skin?

Dragon skin is a resource that is rarer than ordinary medicinal herbs.

Seeing that Hermione and Qiu Zhang were both silent, Dolly said, "I heard from Harry that someone in Ron's family seems to be raising a dragon?"

116 Strengthening Potion, New Idea!

Hermione and Qiu Zhang looked at each other in confusion. They obviously didn't know this information.

Dolly only said it so that the two people would have some impression. She had known about this situation for a long time.

That is the second son of the Weasley family, named Charlie Weasley. He should have graduated by now. After graduation, he studied dragons in Romania.

In the near future, he will also take the initiative to help Hagrid take away his pet Norwegian Ridgeback Norbert.

Originally, Dolly would not have had much interaction with him, but now Dolly is really interested in the material of dragon skin.

It was not just an attempt to block the "magic wave", but also because Dolly wanted to see if she could strengthen the dragon skin and make it into an anti-magic material.

If that's possible, then with the anti-magic mithril and the dragon skin suit, Dolly would be truly confident that she could be invincible in the magic world.

At least it would be difficult for anyone to kill her easily.

The three of them chatted briefly for a few more minutes, and after confirming that this plan was indeed feasible, they prepared to wait for Dolly to obtain the dragon skin before making the next attempt.

As for the other direction, which was to remove the interference of the magic wave, the three of them had no idea about this matter and could only give up.

After this meeting, Hermione felt much more relaxed about Dolly doing research alone, because it didn't seem to be dangerous.

Qiu Zhang also secretly memorized the location and entry method of the Room of Requirement, preparing to come and play with Dolly when he had the chance.

Dolly was also preparing to make the final and most dangerous attempt, which was to take the bone spirit that she had brewed.

What is dangerous is not the Bone Spirit itself, but the Bone Spirit that Dolly brewed. Although it looks exactly the same as the one in the book, Dolly still does not know what its specific effects are.

You have to try it before you know it, this is the most dangerous thing.

In addition, Dolly didn't want others to know this, including Hermione and Qiu Zhang, as well as the house-elf Diandian.

Because no matter how good Diandian's relationship with Dolly is, he is still a house-elf contracted by Hogwarts, not a servant loyal to her.

So at this time, Dolly decided to face it alone.

After seeing Hermione and Qiu Zhang off, Dolly finally took out the raw bone spirit she had brewed.

Looking at the bright liquid inside, Dolly finally hesitated because the pain brought to her by the Bone Spirit was too great.

But in the end, Dolly brought it to her mouth, but at this moment, Dolly suddenly had an idea.

"Sister Men, can I strengthen this potion?"

【Can. 】

Miss Men's answer instantly opened the door to a new world for Dolly. She quickly asked, "So what are the effects of strengthening?"

Try it yourself.

Dolly curled her lips. As expected of Miss Men, she still looked so arrogant and indifferent.

Dolly glanced at her attribute points. Ever since she used the 20 attribute points she had accumulated to strengthen her magic power at the end of February, Dolly's attribute points had reached nine in the past month.

There are naturally enough attribute points to strengthen the potion.

Dolly took a deep breath, gritted her teeth, and used some attribute points to strengthen the potion in her hand.

At the same time, she prayed that the properties of the potion would appear, but the result disappointed Dolly.

Miss Men just reminded Dolly that the Bone Spirit in her hand had turned into Bone Spirit +1, and then there was no movement.

The potion in Dolly's hand also did not show any properties.

What kind of situation is this?

Could her potion be fake?

Dolly picked up the blood-replenishing potion that Snape had brewed for him, gritted her teeth and chose to strengthen it.

This time the result left Dolly speechless.

Because this time the blood-replenishing medicine actually has some attributes.

[Blood-tonifying medicine plus one, renamed as Essence Blood-tonifying Medicine: drug effects are enhanced, and drug side effects are reduced.]

Sure enough, it wasn't that the system was ineffective, but that the bone spirit she brewed couldn't achieve the effect of a qualitative change with just a few attribute points.

What should I do?

Continue to strengthen?

Dolly thought about it and decided to try this bottle of blood-replenishing essence first.

She sacrificed another attribute point of blood, and then immediately drank a sip of blood-replenishing potion.

Then she closed her eyes and felt this bottle of essence blood-replenishing medicine. Soon Dolly felt it. It was basically the same as ordinary blood-replenishing medicine.

But suddenly, Dolly felt a kind of hunger in her body, which made her want to drink the whole bottle of blood tonic.

Dolly opened her eyes curiously, but she felt the blood-replenishing medicine gradually transform into a warm force in her body, and realized that it was harmless.

Then I continued to drink a sip to experience the feeling brought by this blood-replenishing medicine.

Soon, this feeling appeared again, and Dolly's whole body became warm as if she was soaking in a hot spring.

Because she frequently took blood-enriching medicine, she gradually developed symptoms of anemia, including cold hands and feet and a pale face.

This is also one of the reasons why Dolly was actually considered a sickly girl by others, and Dolly had no good way to deal with it. After all, this condition did not really affect Dolly's health.

Before school started after the Christmas holidays, she went to the hospital alone for a series of physical examinations.

The examination results showed that she was just a little weak and had no other symptoms. Dolly was relieved.

All this proves that Dolly's continuous use of blood-enriching drugs does have some side effects, but these side effects will not appear in the short term.

But now, Dolly had a vague feeling.

Not to mention the side effects, the strengthened blood-replenishing medicine might even repair the subtle deficiencies in her body that she couldn't even feel.

This is actually not difficult to understand.

After all, this bottle of blood-replenishing medicine cost Dolly one entire attribute point, so it should represent the value corresponding to 1cc of blood.

The only question is, will the damage it does to Dolly's body be greater than the damage caused by the 200cc, or less than that?

It's unlikely to be greater than that, because if so, wouldn't that be some kind of perpetual motion machine?

Thinking of this, Dolly asked Miss Men.

Miss Men's answer was the same as always, letting Dolly figure it out for herself.
