Update: When Sherlock woke up, he was already lying in a hospital bed at Hogwarts.

Although there is no strong smell of disinfectant here, but when I open my eyes, it is still a vast expanse of white.

"It's nice, I love white."

This was the first sentence he happily said after waking up.

"It looks like the mood hasn't dropped yet."

A dull voice sounded beside him.

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

"Oh! We have come out of the underground, what a delight!"

Shilk helped him shake the bell in front of the bed and helped call Madam Pomfrey over.

"You're happy enough."

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

Just as Sherlock was chattering about a very happy topic, Madam Pomfrey came over with a bottle of potion.

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

"This bottle of grief potion should help him restrain himself, but I'm not quite sure how much to take," Madam Pomfrey said tangled.

Sherlock shook his head happily.

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

However, no one would take what he said now. Madam Pomfrey studied Sherlock's current state for a while, and finally determined the dosage of the potion, and then supervised him to drink the entire bottle of sorrow potion with her own eyes.

Hilke did not leave, but stayed with him by the hospital bed.

After drinking the potion prepared by Madam Pomfrey, Sherlock's state was significantly relieved, the smile on his face gradually subsided, and he could communicate with others normally.

"It seems that you need to be careful 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 will be happy for a week or two at most.

But if something like this happened in a crucial battle, it would still be troublesome.

Just when he was feeling a little down, Sherlock suddenly found an old locket on his neck that he had never seen before.

"What is this?" He took the dark golden round locket and frowned.

Shilk also noticed this thing at this time.

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

Sherlock shook his head.

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

He tried to take the locket off his neck, only to find 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, and no matter how hard he tried, he couldn't get it off.

Sherlock's face turned serious.

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

"Is this thing on the grass man?"

Shilk also realized that something was unusual.

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

Suddenly, she seemed to think of something.

"Its strength is enhanced by fear. If it was its strength in its heyday, it would not be as weak as it is now. But all its actions after escaping to England have been very low-key, and it does not mean to spread fear to restore strength, but to Came straight to Hogwarts."

"It's looking for something."

Sherlock looked down at the locket hanging on his body and tried to open it, but without success.

There is clearly no snap on the box, but there is just no way to open it from the outside.

"Maybe 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 you can tell me what that grass man is?"

Shirk said calmly.

"This is the top secret of the German Ministry of Magic, and it is also the object of the main research and supervision of the Department of Mysteries for the past 100 years."

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

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

"Azkaban?"

Sherlock's eyebrows rose.

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

The Dementors and Azkaban are almost symbiotic existences.

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

At the beginning of the fifteenth century, the island never appeared on any map, not on a Muggle or wizarding map.

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

Existing has gone crazy since he came to this island.

His magic is extremely powerful, and he often conducts some diabolical experiments in black magic, and takes pleasure in luring, torturing and killing Muggle sailors in his path.

At that time, the Ministry of Magic was just a prototype, not really established, only the Great Court of Wizards - Wizengamot was a weak management of the magical world.

Azkaban, which is far away from the British island, was naturally not taken seriously by them. It was not until after the death of Extius that he set a hidden spell on the island to invalidate, and the wizard discovered the island.

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

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

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

But Dementors and the Ministry of Magic were never an employment relationship, but a partnership.

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 are indeed destroyed.

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

So building it into a wizarding prison, actively sending prisoners to the island, and feeding the dementors to prevent them from running out, became the perfect solution.

It can be said that the island is the most evil place in the magic world in a hundred years.

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

Shilk spoke softly.

"It does not have a fixed shape, but when necessary, it can create an entity by itself, which is the appearance of the grass man."

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

"In eighteenth-century northern Europe, it caused a series of horrific massacres, and in some places, entire towns of Muggles were killed by it."

"Retelling the dead words of the dead is its greatest joy, and torturing the living with the words they fear most is its favorite game."

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

"Until one day, a powerful wizard defeated it, only to find that he could not kill it at all, but to capture it and bring it 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 Silence. Until now, the person who guards this demon is me."

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

After Sherlock listened to the whole story of Shilk's story, he was even more worried in his heart.

"I was imprisoned for more than two hundred years. The first time I came out was not to think about how to escape and not be caught back, but to find this thing. It sounds like a trouble."

At this time, Shilk discovered that Sherlock was emotionally wrong.

"The amount of the potion seems to be too much for you."

She shook the bell again and called Madam Pomfrey over to check on Sherlock's current state.

"How are you feeling now?" Madam Pomfrey asked seriously.

Sherlock replied feebly.

"It's not good, it feels terrible, it's not interesting to see anything, I don't seem to have much time, I can't live."

Madam Pomfrey nodded with satisfaction.

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

Sherlock was discharged from the hospital unhappy.

"This thing is most likely found in the goblin's abandoned headquarters. I can find the goblin in the department and contact the goblin I communicated with before. Maybe he may know something."

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

He continued to the third floor by himself, intending to go directly to Dumbledore to see if he could help him get the locket off his neck.

Sherlock walked down the stairs staggeringly, just as the students had just finished class at this time.

The whole school was put to sleep in the Great Hall last night after Blackjohn broke into the Gryffindor lounge.

After the professors had ruled out the entire castle to make sure that Blake was not hiding somewhere in Hogwarts, the school was back to normal teaching order the next day.

When he walked slowly to the third floor, he happened to meet the three of them, Harry, 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 but throw a barrage of questions.

Sherlock looked at him weakly and said sadly.

"Ah, I wanted to go to the Halloween dinner too, but I missed it. As for Blake breaking in, that's really bad news, Harry, it looks like you haven't had much luck these two days. I'm going to look for it. Dumbledore has something to talk about, I don't have time to talk to you more, goodbye."

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

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 had reacted, "Professor said I wasn't very lucky these two days!"

Ron looked at him with envy.

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

Harry looked longing.

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

Hermione frowned.

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

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

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

They quickly focused their attention on this matter excitedly, and Sherlock also walked 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 asked Dumbledore in the office in some way, and then made way for Sherlock and let him go in.

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

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

"You're not in a good mood? Sherlock~lightnovelpub.net~ Sherlock sat opposite Dumbledore, his upper body lying on his desk like a boneless body.

"Mrs. Pomfrey gave me an overdose of the grief potion, and now I'm really sad."

Dumbledore frowned slightly.

"I know you went out with Shilk yesterday, so what happened to you last night?"

Sherlock used a sad voice to retell their experience last night, and finally put the locket around his neck that couldn't be removed in front of Dumbledore.

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

Sherlock was lying on the table, just enough for Dumbledore to pick up the locket.

He looked at the old, dark-gold round locket, and frowned gradually.
