When Sherlock woke up, he was already lying on the bed at Hogwarts School Hospital.

Although there is no strong smell of disinfectant here, it is still white when you open your eyes.

“It’s very good, I like the white very much.”

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

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

A plain voice sounded next to it.

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

"Oh! We've come out of the ground, it's a pleasure!"

Shilk helped him shake the bell in front of the bed and helped him shout Mrs. Pomfrey over.

"You're happy enough."

"Don't always be stern, Shilk, be happier, we have to laugh, for example, now, I feel that I am in a great state! I am in very good condition, and I even feel that I can be happy like this all the time!"

Just as Sherlock was chatting about very happy topics, Mrs. Pomfrey walked over with a bottle of potion.

"His condition is indeed as you said, a little overexcited." Mrs. Pomfrey once again determined Sherlock's current condition with his own eyes, "a bit like overdrinking the rejoicing potion."

"This bottle of sadness potion should help him suppress it, but I am a little confused about how much it takes." Mrs. Pomfrey said in confusion.

Sherlock shook his head happily.

"Sad potion? I don't want to be sad. Isn't happiness good? Why do people feel sad?"

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

Shilk had not left, but stayed by the hospital bed.

After drinking the potion configured by Mrs. Pomfrey, Sherlock's condition obviously eased a lot. The smile on his face gradually subsided and he could communicate with others normally.

"It seems that you should be careful when using such a guardian spell in the future." Sherlock said with a headache.

Although positive emotions overflowing is not a big problem, even without Mrs. Pomfrey's potion, he would be happy in a week or two at most.

But if such a thing happens in a critical battle, it is still very troublesome.

Just when he was feeling a little depressed about this, Sherlock suddenly found that there was an old locket on his neck that had never been before.

"What is this?" he said with a frown, holding the dark golden round locket.

Shilk also noticed this thing at this time.

"Didn't you bring 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 remove the locket from his neck, but found that he could not do it at all!

There was an invisible obstacle on his body, blocking the chain of the locket between his neck and his head. No matter how he tried, he could not take it off.

Sherlock's face became solemn.

Instead of trying to remove it from himself, he looked at Shilk.

"Is this thing from that straw man?"

Shilk also realized that things were a little unusual.

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

Suddenly, she seemed to have thought of something.

"Its power is enhanced by fear. If it was its heyday, it would not be as weak as it is now. But after it fled to Britain, all its actions were low-key, and there was no intention of spreading fear and restoring its power, but came directly to Hogwarts."

“It’s looking for something.”

Sherlock looked down at the locket hanging on him and tried to open it, but failed.

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

"It is possible that this thing is what it is looking for?" Sherlock said dullly.

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

He looked at Shilk.

"Can you tell me what that straw man is?"

Shilk said calmly.

"This is the highest secret of the German Ministry of Magic and the main target of the Mysterious Things Department for the past century."

When Sherlock heard her say this, she thought she was just rejecting it, but she didn't expect that she continued.

“Its name is Fiddlesticks, originally from Azkaban.”

“Azkaban?”

Sherlock raised his eyebrows.

The original owner was an expert in studying dark creatures, and the most famous dementor was his main research object.

And Dementor and Azkaban are almost symbiotic existences.

Azkaban is now the most notorious wizard prison in the magic world, but at the beginning, it was actually just an ordinary island on the North Sea.

At the beginning of the fifteenth century, the island never appeared on any map, and there was no map of Muggle or Wizard.

Until one day, a wizard named Axtis came to the island and built a castle here, and then lived alone here.

After Axtis arrived on the island, he went crazy.

His magic is extremely powerful, and he often conducts some extremely evil black magic experiments, and enjoys seducing, torture and killing the Muggle sailors here.

At that time, the Ministry of Magic was just a prototype and had not been truly established. Only the Great Wizard Court, Wisengamo, had weak management of the magic world.

Azkaban, far from the British island, naturally did not receive their attention. It was not until after Axtis died that he set up a hidden spell on the island that failed, and a wizard discovered the island.

But it is already filled with hundreds of terrifying monsters that can absorb people's hope - Dementors.

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

The island was later regarded by the Ministry of Magic as a prison for wizard criminals, and all the dementors inside became prisoners.

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

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

It’s not that the Minister of Magic has proposed to destroy that island, but the island can be destroyed, and the dementors are indeed not completely destroyed.

They were afraid that these monsters would flee to the British island and cause even greater trouble.

So it was built into a wizard prison, and the prisoners were sent to the island, allowing the dementors to fill their stomachs to prevent them from running out, which became the most perfect solution.

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

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

Shilk told him softly.

"It has no fixed form itself, but when necessary, you can create an entity by yourself, which is the appearance of the straw man."

"It is even more terrifying than the dementor. The dementor just sucks hope, but it wants to create fear, enjoy devouring the soul full of fear, and become powerful by this."

"In Northern Europe in the eighteenth century, it caused a series of tragic massacres, and some places, even a whole town of Muggles were killed by it."

"Retelling the dead's words is its greatest pleasure. Torturing them with the most feared words of the living is its favorite game."

"The scarecrow with a sickle in one hand and a lantern in the other was the most widely circulated horror story among the Muggles during that period."

"Until one day, a mana-powered wizard defeated it, but found that it could not be killed at all, so he could only capture it and bring it back to the newly established German Ministry of Magic."

"Since then, Federtic, the demon who controls fear, has been imprisoned in the Mysterious Affairs Division of the German Ministry of Magic, guarded by the Silent Man. Until now, I am the one who guards this demon."

"But it has not stopped resisting. For nearly two hundred years when it was locked in the Ministry of Magic, it has been secretly accumulating its strength until it escaped four months ago."

After listening to Shilk's talk, Sherlock became even more worried.

"I have been imprisoned for more than two hundred years. The first time I came out was not thinking about how to escape and not be caught, but to find this thing, which sounds like a problem."

At this time, Shilk discovered something wrong with Sherlock.

"That bottle of potion seems to be a little too much for you."

She shook the bell again, called Mrs. Pomfrey over and checked Sherlock's current condition.

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

Sherlock replied weakly.

"Not really, I feel so bad. It's meaningless to see anything. It seems that I have not had much time and I can't live anymore."

Mrs. Pomfrey nodded with satisfaction.

"Fortunately, the sad potion is not too much, but I just feel that I can't live. If I feel suicidal, I will feed you some joy potion to neutralize it. Now, it will probably take less than a week to recover."
