Hogwarts starts with stealing power.

Chapter 226: The first student to be petrified, Hogwarts is unsealed, and the formula for the guardian button is available
Harry was speechless about Dobby, the house-elf.

“You wanted to kill me, even if you hurt yourself, you still wanted to kill me.

That Bludger nearly shattered me to pieces, and even that time on the King's Platform, you nearly got me expelled from Hogwarts, you..."

"Oh, if only Harry Potter knew!"

Dobby suddenly covered his head, groaning helplessly, tears rolling down his tattered clothes.

"If only I knew what he means to us lowly, enslaved little creatures of the wizarding world!
I have not forgotten He-Who-Must-Not-Be-Named, at the height of his power, sir, people treated us house-elves like vermin, and of course they still treat Dobby that way now, sir."

Dobby wiped his tears.

"But overall, since you defeated He-Who-Must-Not-Be-Named, life for the rest of us has improved a lot...

Harry Potter shines like a beacon of hope... and now, at Hogwarts, something even more terrible is about to happen... history is about to repeat itself and the Chamber of Secrets is about to be opened once again."

Harry interrupted Dobby.

"Wait, a secret room? So there really is a secret room?
And you said it had been opened before. Tell me, Dobby, how many years ago was it? Who opened it?"

Dobby was stunned, realizing he had said something wrong, and was terrified.

It grabbed Harry's pitcher from the bedside table and banged it against its head again and again, then staggered away.

But soon after, it slowly climbed onto the bed again, stared at me, and muttered in a low voice:
"Bad Dobby, good bad bad Dobby! Dobby shouldn't have told Harry Potter these things!"

The house-elf stammered, his eyes as big as brass bells in the darkness.

"Someone is plotting a conspiracy here, and Harry Potter must not stay here while it's happening!

Go home, Harry Potter, go home, you must not interfere in this matter, it is too dangerous..."

Just as Dobby was about to disappear, Harry grabbed Dobby's arm in time to prevent him from hitting his head with the pitcher again or leaving.

"Who is that, Dobby? Tell me, who opened the Chamber of Secrets?"

Dobby shook his head desperately, "Dobby can't say it, sir, Dobby can't say it, Dobby absolutely can't say it!"

The elf screamed, still repeating the same words: "Go home, Harry Potter go home."

Harry said irritably, "I'm not going anywhere. I have a friend who is a Muggle-born. If the Chamber of Secrets is really opened, she will be the first to bear the brunt -"

Suddenly, there was a sound of footsteps coming from the corridor outside.

Harry was just stunned for a moment, and the next second, the house-elf disappeared from in front of him.

Harry fell back onto the bed, his eyes fixed on the dark ward door as the footsteps got closer.

Then there was a flash of light, the door of the ward opened, and the first person to appear was Dumbledore.

He entered the ward, holding something like a sculpture in his hands.

A few seconds later, several other professors appeared, carrying the other end of the thing.

Together they put the object on the bed.

Madam Pomfrey hurried over.

"What's going on?" she asked Dumbledore in a low voice, bending over the object.

A pale moonlight shone on the object, and Harry finally saw the whole appearance of the object clearly -

It was Colin Creevey.

His eyes were wide open, his hands stretched out in front of his chest, holding a camera, and in the other hand he held a bunch of grapes.

Professor McGonagall said, "We guess he wanted to sneak in here to see Potter."

Harry felt his stomach twist violently.

How could this happen? Why did this happen?

Madam Pomfrey examined him closely. "He is petrified?"

"Yes," said Professor McGonagall, "I shudder to think of it..."

Someone asked: "Will he take a photo of his attacker?"

Dumbledore did not reply, but pried open the back of the camera.

"Oh my God!" Madam Pomfrey exclaimed.

A hiss of hot air came out of the camera, and even Harry, who was three beds away, could smell the pungent smell of burning plastic.

"Melted," Madam Pomfrey said in surprise, "It actually melted..."

"What does this mean, Albus?" Professor McGonagall asked eagerly.

"This means," Dumbledore paused, "that the Chamber of Secrets has indeed been opened."

……

The news that the Chamber of Secrets was opened quickly spread throughout Hogwarts.

There was also news that a student was petrified, the unfortunate one - Colin Creevey.

Headmaster Dumbledore decided not to seal off Hogwarts any longer, leaving it up to the young wizards to decide whether to leave or return home.

Hogwarts seemed to have reached its darkest hour.

Even Lin Xia did not expect the unblocking order to come so quickly.

When they went to visit Harry, they also saw Colin Creevey, who was petrified.

Harry woke up to a patch of sunlight to hear Hermione's excited voice.

"Therefore, we must investigate whether the secret room being opened has any necessary connection with petrification!"

Ron was confused: "What other connection could there be? The cleaner of the secret room has decided to come out and clean it up!"

Lin Xia shook her head: "No, Ron, you don't understand what Hermione means.

Hermione was asking what the relationship between the Sweeper and the Chamber of Secrets was. Since the Sweeper would only appear after the Chamber of Secrets was opened, how did the Sweeper work and why did the first move of the Sweeper petrify the body?"

Harry moved his body and found that new bones had grown in his arms, but they were very stiff.

He joined the discussion: "That sweeper must have looked very scary. When Colin was petrified, his eyes were full of fear."

Lin Xia started the conversation by saying, "I've read a book about magical creatures before, and one of the magical creatures is called a basilisk. It was artificially created by wizards, and anyone who looks into the eyes of a basilisk will be petrified..."

She paused, "And currently the person who is known to be able to create a basilisk is a great wizard named Slytherin Salazar."

Draco immediately understood what Lin Xia meant.

"You think they encountered a basilisk?"

Lin Xia said solemnly: "I don't want to speculate in this direction, but their petrification technique is too powerful. I heard from the professor that this requires a very high level of attainment in black magic.

I think as a wizard, first of all, I can't live that long. Only magical creatures can do that.

Secondly, the petrification of the basilisk is triggered passively, not actively, so it is normal that humans and cats don’t have time to react.”

Lin Xia's words gave a new direction.

Harry said at this time: "Actually... just last night, I heard that voice again. It said it was very hungry and wanted to kill someone... and not long after, Colin was petrified.

I've heard that sound before. It keeps moving, as if it's moving from the ground to the ceiling.

I thought at the time that the voice was a ghost, but that was impossible, ghosts didn't have such powerful abilities.

After hearing what Lin Xia said, I realized that it was most likely a basilisk!"

Ron's eyes flickered constantly, and he was thinking rapidly.

"Brassizor, Basilisk..." His eyes lit up, "Pipeline! There are many pipes in Hogwarts. Maybe it swam through the pipes!"

Lin Xia discouraged them from taking risks. "There are many pipes laid in Hogwarts. If you don't know the correct route, you will just be searching aimlessly.

Don't forget that Hogwarts installed heating and redid the plumbing a few years ago.

Don’t let yourself get burned by the scalding steam before you find the basilisk when you pass through the pipe.”

These words dispelled Ron and Harry's idea.

Draco and Hermione couldn't help but look at Lin Xia, but Lin Xia didn't say something.

The weather isn't cold enough right now, the heating isn't even on!
If you go to climb the pipeline now, you can search for it.

But Lin Xia was right about one thing: if you search without a purpose, it is just a blind search.

Hogwarts is so big and there are so many pipes. Who knows which pipe to start looking for?
In addition, if we really start from the pipe, what if we accidentally encounter a basilisk while searching?
If you look into the eyes of a basilisk, you will be petrified!
When things weren't moving forward, Harry came up with a whole new direction.

"Dobby, do you remember Dobby? He came to me last night and told me to leave Hogwarts before Colin was petrified."

Harry paused, "It also told me that the Chamber of Secrets had been opened, that history was about to repeat itself, that Hogwarts was no longer safe, and that I had to go home.

So the Quaffle that went out of control during the Quidditch game was controlled by it, and it wanted to force me to go home!"

"Dobby?" Ron and Hermione frowned.

They were not very familiar with the territory of house elves.

Lin Xia looked at Draco.

Draco said solemnly, "I'm waiting for a reply from my family. I should have news this week."

Harry wasn't well yet, so the group had to bring him food.

They went to the Great Hall and found that some wizards were missing.

Some wizards felt that Hogwarts was unsafe and had left.

But most wizards stayed because they believed in Hogwarts!
After this incident, the guardian amulets and guardian buttons became popular again.

There were all kinds of strange things, such as amethyst, cross, garlic, and water in a silver cup...

The school's grocery store finally couldn't withstand the pressure.

Anything related to "guardianship" is sold out and is completely out of stock.

As for Guardian Button, the orders have piled up in countless numbers.

Lin Xia had asked them to stop the pre-orders long ago.

It was also at this time.

The school has finally discussed the price of the formula for the intellectual property "Guardian Button".

The issue of price.

In theory, Lin Xia's team has absolute autonomy in pricing.

Even the Guardian Button was created in the Hogwarts laboratory.

Lin Xia still has absolute power to handle the matter.

Everyone knows that although laboratory conditions are good, whether something can be created depends on people.

The school doesn’t just give Lin Xia a laboratory; other senior students also have laboratories.

But only Lin Xia's team produced remarkable results, what about the others?
There’s not even a prototype yet!

The reason why Lin Xia asked the school to set the price was because she wanted to spread the formula of the "Guardian Button" through the school's channels.

So, she is actually working with Hogwarts.

She can make concessions on pricing power.

As for Lin Xia's proposal of sharing the profits from the items sold, after discussion, it was unfortunately not possible.

After all, this is not publishing a book, so there is no so-called royalties.

In addition, once the formula of the Guardian Button is sold, it will definitely be produced in large quantities.

The profits generated here are so huge that it is very difficult to get a share of the profits.

Lin Xia had expected this and was not surprised.

In Professor McGonagall's office.

Mag told Lin Xia the final result of the school's negotiation: "The sales right of the formula is one gold galleon, and the school will extract 20% of the promotion fee, but at the same time, the school will fully help you promote the Guardian Button."

Lin Xia keenly noticed a word, "comprehensive?"

Professor McGonagall nodded slightly and said seriously, "Yes, I will help you promote it in a comprehensive and unreserved manner."

Lin Xia asked: "Excuse me, what kind of promotion strength is this?"

McGonagall: "In addition to the excellent student channels that Hogwarts has, there are other channels that will help you promote.

For example, the Alchemist Association channel, the famous alumni channel, the jeweler channel, the strange item merchant channel...

Hogwarts can help you with any channel that has the key.

At the same time, the Guardian Button will be brought to the whole world, not only to the British wizarding world, but also to the American wizarding world, the French wizarding world, and the Egyptian wizarding world..."

After hearing this, Lin Xia couldn't help but be shocked by the generosity of Hogwarts.

She couldn't help but ask, "Professor McGonagall, is it worth it to protect the button?"

With such a promotion effort, only 20% of the promotion fee will be charged?

That is a great conscience!

Professor McGonagall smiled and said meaningfully, "Lin Xia, any item related to [protection] is worth doing this for.

And the Guardian Button fills the vacancy of the Guardian Talisman to the next level.

Maybe from now on, more and more strange objects related to protection will appear in the wizarding world, which will be very useful in another place."

Lin Xia's eyes flashed slightly.

She thought for a while and said solemnly: "I accept this condition!"

Immediately, Lin Xia signed the contract with Hogwarts.

Professor McGonagall reminded her: "When you go back, you can open the excellent student key and check it in the mall with the Alchemist Association key."

Lin Xia left the office.

She turned to look out the window.

The weather has been bad recently, with dark clouds all over the sky. There's always a feeling that dark clouds are looming over the city and a storm is about to come.

There are no classes in the afternoon.

Lin Xia did not go to visit Harry, but opened the secret key to check.

As expected, the mall sections of the Excellent Student Key and the Alchemist Association Key have both listed a product—

【Guardian Button Formula】, author: Lin Xia
Price: 1 Galleon

As for the excellent student key, it shows that 10 people have purchased it.

But when it was placed at the Alchemist Association's secret key, 100 people had already bought it!

At the same time, some wizards also gave purchase ratings.

[A very simple and easy-to-understand protective item. It is hard to imagine that, apart from the protective amulet, there has been no related protective products in the wizarding world for so many years. It took a genius little wizard to create it!]
