Chapter 134 The Unremovable Locket
When Sherlock woke up, he was already lying on a hospital bed at Hogwarts School Hospital.

Although there is no strong smell of disinfectant here, it is still a vast expanse of whiteness when you open your eyes.

"Very nice, I like white very much."

This was the first sentence he uttered cheerfully after waking up.

"It seems that the mood has not subsided yet."

A flat voice sounded from the side.

Sherlock tilted his head and saw Silk sitting next to him.

"Oh! What a joy we have come out of the ground!"

Silk helped him shake the bell in front of the bed and called Madam Pomfrey over.

"You're happy enough."

"Don't keep a straight face, Silke, be happy, we have to laugh, like me now, I feel that I am great! The state is very good, and I even feel that I can continue to be happy like this!"

While Sherlock was chatting about very happy topics, Madam Pomfrey came over with a bottle of potion.

"His state is indeed as you said, a little over-excited." Madam Pomfrey once again confirmed Sherlock's current state with her own eyes, "It's a bit like drinking a euphoria potion too much."

"This bottle of sadness potion should be able to help him suppress it, but I'm not sure how much to take." Madam Pomfrey said tangled.

Sherlock shook his head happily.

"Sad potion? I don't want to be sad, isn't it good to be happy? Why should people be sad?"

However, no one would take his words seriously now. Madam Pomfrey studied Sherlock's current state for a while, finally determined the dosage of the medicine, and then supervised him to drink the whole bottle of sadness medicine with her own eyes.

Silk didn't leave, and stayed with him by the hospital bed.

After drinking the potion prepared by Madam Pomfrey, Sherlock's state became much more relaxed. The smile on his face gradually subsided, and he was able to communicate with others normally.

"It seems that you should be cautious when using such a Patronus Charm in the future." Sherlock said with a headache.

Although the overflow of positive emotions is not a big problem, even without Madam Pomfrey's potion, he can recover within a week or two at most.

But if something like this happens in some critical battle, it will still be very troublesome.

Just when he felt a little depressed about this, Sherlock suddenly found an old locket around his neck that he had never had before.

"What is this?" He held the dark gold round locket and said with a frown.

Silk also noticed this thing at this time.

"Didn't you take it with you before you went underground?" Her tone became slightly serious.

Sherlock shook his head.

"No, I've never seen this thing before."

He tried to remove the locket from his neck, but found that he couldn't do it at all!
There seemed to be an invisible barrier on his body, blocking the chain of the locket between his neck and head, no matter how hard he tried, he couldn't get it off.

Sherlock's face hardened.

Instead of trying to take it off himself, he looked at Silk.

"Is this thing from that straw man?"

Silk also realized that something was unusual.

"No, when it escaped, it didn't have this thing on it."

Suddenly, she seemed to think of something.

"Its power is enhanced by fear. If it was at its heyday, it would not be as weak as it is now. But after it fled to the UK, all its actions were very low-key, and it didn't mean to spread fear and restore its strength, but Straight to Hogwarts."

"It's looking for something."

Sherlock looked down at the locket hanging on his body, trying to open it, but failed.

There is obviously no clasp on the box, but there is no way to open it from the outside.

"Is it possible that this thing is what it's looking for?" Sherlock said dully.

For some reason, his mood suddenly began to turn bad again, a little sad and a little lost.

He looked at Silk.

"Now, can you tell me what that straw man is?"

Silk said calmly.

"This is the top secret of the German Ministry of Magic, and it has been the main research object of the Department of Mysteries for nearly a hundred years."

When Sherlock heard her say this, he thought she was refusing, but unexpectedly, she continued.

"It's called Fiddlesticks, and it's originally from Azkaban."

"Azkaban?"

Sherlock raised his eyebrows.

The original owner is an expert in the study of dark creatures, and the most famous dementor is his main research object.

Dementors and Azkaban are almost symbiotic existences.

Azkaban is now the most notorious prison for wizards in the entire wizarding world, but in the beginning, it was actually just an ordinary island in the North Sea.

In the early fifteenth century, the island never appeared on any maps, neither Muggle or wizarding.

Until one day, a wizard named Extis of unknown nationality came to this island, built a castle here, and lived here alone since then.

After Extis came to this island, he had gone mad.

His magic is extremely powerful, and he often conducts some extremely evil black art experiments, and takes pleasure in luring, torturing and killing Muggle sailors passing through here.

At that time, the Ministry of Magic was only in its infancy, and it was not really established. Only the Wizengamot, the Grand Tribunal of Wizards, managed the magic world weakly.

Azkaban, which was far away from the main island of Britain, naturally did not receive their attention. It was not until Extis died that the hidden spell he set on the island became invalid, and only wizards discovered the island.

But it is already filled with hundreds of terrifying monsters that can suck people's hopes-dementors.

This is the earliest relevant record of large-scale group dementors in the history of the wizarding world.

The island was later used by the Ministry of Magic as a prison for wizarding criminals, and all the dementors in it became jailers.

But the relationship between Dementors and the Ministry of Magic has never been an employment relationship, but a cooperative relationship.

The existence of monsters like dementors is completely anti-human.

It's not that the Minister of Magic has proposed to destroy the island, but the island can be destroyed, and the dementors can't be wiped out.

They are afraid that these monsters will escape to the British island and cause more trouble.

So it was the perfect solution to build it into a wizard prison, take the initiative to send prisoners to the island, and feed the dementors to prevent them from running out.

It can be said that that island is the most evil place in the magic world in the past century.

"Before the British Ministry of Magic set up a prison on that island, someone explored that island and brought out an evil spirit from it—Fiddlesticks."

Silk spoke softly.

"It doesn't have a fixed form, but it can create an entity by itself when necessary, just like the straw man."

"It's more terrifying than a dementor. A dementor just sucks hope, but it wants to create fear, and it takes pleasure in devouring fear-filled souls, and it becomes powerful."

"In northern Europe in the eighteenth century, it caused a series of tragic massacres. In some places, even an entire town of Muggles was killed by it."

"Retelling the death words of the dead is its greatest pleasure, and torturing the living with their most feared words is its favorite game at ordinary times."

"The scarecrow with a scythe in one hand and a lantern in the other is the most widely circulated horror story among Muggles at that time."

"Until one day, a powerful wizard defeated it, but found that it could not be killed at all. It could only be captured and brought back to the newly established German Ministry of Magic."

"Since then, Fiddlesticks, the fear-manipulating demon, has been imprisoned in the Department of Mysteries of the German Ministry of Magic, guarded by the Silent Man. Until now, I am the one who guards this demon."

"But it has never stopped resisting. During the nearly 200 years it has been locked in the Ministry of Magic, it has been secretly accumulating strength until it escaped four months ago."

After Sherlock listened to Silk's story, he became even more worried.

"I was imprisoned for more than 200 years. The first time I came out was not to think about how to escape without being caught, but to find this thing. It sounds like it is a trouble."

At this time, Silk found out that Sherlock's emotions were not right.

"The amount of that bottle of potion seems a bit too much for you."

She rang the bell again and called Madam Pomfrey over to check Sherlock's current status.

"How do you feel now?" Madam Pomfrey asked seriously.

Sherlock replied weakly.

"It's not good. I feel terrible. It's not interesting to watch. I don't seem to have much time to live."

Madam Pomfrey nodded in satisfaction.

"Fortunately, the sadness potion is not too much, it's just that you feel that you can't live. If you feel suicidal, I will give you some joy potion to neutralize it. Now it will take less than a week. It will recover naturally."

Sherlock was discharged from the hospital depressed.

"It is very likely that this thing was found from the goblin's abandoned headquarters. I can find the department and contact the goblin I communicated with before. Maybe he may know something."

Silk and Sherlock parted in the corridor on the fifth floor.

He continued to walk to the third floor alone, planning to go directly to Dumbledore to see if he could help him get the locket off his neck.

Sherlock walked down the stairs unsteadily, at this time the students just finished class.

Because Black forced his way into the Gryffindor lounge last night, all the students in the school were arranged to sleep in the auditorium overnight.

After the professors ruled out the entire castle and made sure that Black was not hiding somewhere in Hogwarts, the school returned to normal teaching order the next day.

When he walked slowly to the third floor, he happened to meet Harry and the three of them who had just finished class.

"Professor, where were you last night? Why didn't you come to the Halloween dinner? Did you know that Blake broke into the school last night?"

As soon as Harry saw Sherlock, he couldn't help asking a series of questions.

Sherlock looked at him weakly and said sadly.

"Ah, I also wanted to attend the Halloween dinner, but unfortunately I still missed it. As for Black breaking in, this is really bad news, Harry, it seems that your luck is not very good these two days. I'm going to find Dumbledore has something to talk about, I don't have time to chat with you, goodbye."

After he finished speaking, he continued to walk downstairs listlessly.

And hearing Sherlock's words, Harry stayed where he was, and Hermione and Ron were also stunned.

"Did you hear that!" Harry shouted in surprise after he realized it, "The professor said that my luck has not been very good these two days!"

Ron looked at him enviously.

"You're going to change Harry's luck, and then you'll definitely be the luckiest person in the entire castle."

Harry looked longingly.

"The best thing I can imagine is that Blake gets caught and someone is willing to sign my parental consent form to go to Hogsmeade for the weekend!"

Hermione said with a frown.

"Professor Forrest seems to be in a bad mood today."

"Although it's a bit bad to say that, if the professor is in a good mood, then we're done for saying hello to him just now." Ron shrugged and said.

"Think about how to spend the next two days, Harry, I think you can inquire if the Daily Prophet is holding any lucky draw recently, and then sign up to get a big prize back."

They quickly focused their attention on this matter excitedly, and Sherlock also walked up to the stone monster on the third floor at this time.

"I want to find Dumbledore, can you inform me?"

The stone monster didn't speak. It seemed to have used some method to ask Dumbledore in the office, and then made room for Sherlock to let him walk in.

Sherlock came to the eighth floor, opened the door and walked into the principal's office.

Dumbledore looked up at Sherlock, and at a glance he saw that he seemed to be in a bad state.

"You're not in a good mood, Sherlock."

Sherlock sat across from Dumbledore, his upper body lying on his desk like a boneless one.

"Madame Pomfrey prescribed me an overdose of grief potions, and now I'm really sad."

Dumbledore frowned slightly.

"I know you went out with Silk yesterday, so what did you guys go through last night?"

With a sad voice, Sherlock recounted their experience last night, and finally placed the locket that could not be removed around his neck in front of Dumbledore.

"Do you know what this is? Professor, or help me get it off of me."

Sherlock's posture on the table was just right for Dumbledore to pick up the locket.

He looked at the old, dark golden round locket, and his brows gradually became more and more wrinkled.
