Dumbledore? He knows nothing about MC alchemy.

Professor Flitwick explained.

"I see... I hope everything is fine."

"Don't worry, Luna is much stronger than she looks."

"uh-huh."

Kaisen put on gloves as he spoke, picked up a piece of mutton and started eating.

At the same time, Hagrid came over with two wine barrels in his arms.

"You know what I'm going to do, right?" Hagrid said, showing his big teeth.

"of course."

Kaisen summoned two wine glasses from the office area.

................................

the next day...

"Forehead............"

"Drink any more and I'll be a dog."

Kaisen climbed out of bed, holding his hungover head, and felt a little better after taking a mouthful of milk with difficulty.

Going downstairs to the office, he looked at the gifts piled up in the corner reaching the ceiling. He rubbed his hands together excitedly and started to open them directly.

Professor McGonagall's dark red wizard hat looks good, put it on.

Professor Flitwick left behind a silver eagle statue.

Professor Sprout gave him a pie that he could never finish... I don't know what kind of magical magic it was, but Kaisen had never seen it before.

Lockhart....what this guy gave was actually a self-portrait...But fortunately it wasn't a magical self-portrait, otherwise he really might not be able to bear it and plant Lockhart in a flowerpot.

But now he is much gentler, like pointing his head upwards.

However, what made him most satisfied was the huge redstone lamp screen built by the young wizards above the Black Lake.

He had shrunk it down and placed it on the desk.

Well, I’m satisfied, indescribably satisfied.

After unpacking all the gifts and letting them know their appropriate locations, I began the arduous task of rebuilding the floor-to-ceiling windows.

Last night, I accidentally destroyed the entire glass.

As cool as it was to knock on the glass back then, rebuilding the window now is as awkward as it is to knock on the glass now.

After spending most of the day rebuilding the floor-to-ceiling window, Kaisen finally took out the magic manual again.

He spread the magic manual flat on the desk, and the map of Slytherin's Chamber of Secrets that he had copied from the Room of Requirement floated above the book like a holographic projection.

You can use your fingers to move it at will until all the disrupted points, lines and surfaces are straightened out.

The only difficulty is that this map is 3D, and it is much more difficult to rearrange it than a 2D one.

"That damn Voldemort brat, you'd better pray that you die quickly, otherwise you will suffer a lot!" Kaisen gritted his teeth and put the puzzle together, not even noticing Dumbledore walking in front of his desk.

"Ahem." Dumbledore coughed twice softly.

"Huh? What's wrong?" Kaisen raised his head and asked.

"No, how did you get in?"

"The office door is unlocked."

"Okay, what's up?" Kaysen asked.

"Remus has run into a little trouble," said Dumbledore.

"Well, you said."

"There's an ambitious werewolf in England called Fenrir Greyback. He bit Remus when he was a child."

"He is an ambitious man and, in a sense, a poor leader. He relies on violence and terror to rule over a large group of werewolves who are not as powerful as him. However, thanks to your enchanted book therapy, a large number of werewolves have been able to shed their werewolf identities."

"Werewolf is no longer an incurable disease. In the past, he only needed to show his claws and the wizards would choose to stay quiet. But now, one Galleon can cure wolfsbane, so he has lost his best ability to intimidate wizards by showing his claws."

"He bears a grudge against you."

Kaisen rubbed his chin.

"So... he holds a grudge against me for asking him to come to Hogwarts to find me. What does this have to do with Lupin?"

"Remus has been running around various werewolf gathering places to promote enchanted book therapy, which has directly turned Greyback's rule into a ridiculous joke, so Greyback has been hunting Remus all this time," Dumbledore explained.

"Oh, Lupin is incredibly skilled. What can a werewolf do to him?"

"Not only to help him defeat Greyback, but also to persuade him to return to Hogwarts to take over the position of Defense Against the Dark Arts professor next semester. Lockhart has formally submitted his resignation to me, and he will go to St. Mungo's at the end of this semester." Dumbledore said somewhat embarrassedly.

"Has he sent out his paper? I was thinking of giving Neville a surprise for Christmas." Kaisen said.

"He will. Mr. and Mrs. Longbottom invited you to spend Christmas with them this year. They sent many letters but you didn't reply, so they asked me."

"Actually...I don't really want to go."

"Then I won't go." Dumbledore naturally put away the letter he had already taken out. "It just so happens that I haven't replied to them yet. Then I can say that the Owlery caught fire or a batch of letters was blown away by the wind."

Dumbledore left, and Kaisen closed the magic manual in his hand.

He refused Neville's parents' invitation without even thinking about it. Firstly, strictly speaking, this matter was Lockhart's credit, and he could only be regarded as a matchmaker.

Also, he really hates visiting other people's homes.

And Lupin, half of the semester has passed and it is almost Christmas.

Kaisen had absolute confidence in his skills. Dumbledore asked him to find Lupin not to really help Lupin deal with Greyback, but mainly to frame Lupin to be the professor of Defense Against the Dark Arts.

Of course it will be next semester. Snape will still be the substitute teacher this semester. To be honest, he has had a great time teaching for almost half of the semester.

Finally, there is that damn 3D map in the magic manual. I have to say that when it comes to mathematical geometry, compared to real geniuses, my skills are still not enough.

However, he did have a solution. He could import the geometric figure into a digital version and have someone who was really good at math solve it. For example, he could go back to his alma mater, Manchester, and find those math experts...

and many more...

Chapter 111 Sherlock Holmes

"Why should I go so far as to find the long way around? Things like finding criminals and secret rooms should be left to professional detectives!" Kaisen suddenly realized that he still had his genius neighbor, Mr. Sherlock Holmes!

I don't need to study the map hard at all......

Going off on a tangent. Going off on a tangent.

No, I got the map by climbing to the eighth floor with Dumbledore on an empty stomach. I still need to make use of it. For example, after finding someone to crack it, I can use the data to make a 3D version of the Hogwarts map. If I add name tracking magic, it can also be used as a surveillance device.

The location of the secret room can be directly deduced by Holmes. England has been relatively quiet in recent years, and this peaceful life is probably enough to make him bored.

I just need to change the nouns, such as changing Hogwarts into an ordinary castle, the basilisk into a pistol, Voldemort into a murderer, Myrtle into an ordinary dead person, and the Chamber of Secrets into the murderer's stronghold.

Searching for the secret room means looking for clues in the murderer's base.

As long as all the magic-related words are explained into words that Holmes can understand, wouldn't the secret of the secret room be revealed?

After being Holmes's neighbor for so many years, I have absolute confidence in his reasoning ability.

After all, that level of reasoning is basically equivalent to Dumbledore's talent in magic. It can be said that in this era, there is no one before and perhaps no one after.

And with Sherlock Holmes's style of thinking that everything can be solved by reasoning...

To be honest, when he first came here, he thought this was a world with reasoning as its theme. After all, if your friend is Sherlock Holmes, no one would have thought that there would be Hogwarts in this world.

After deciding to hand over the task at hand to his lovely neighbor, Kaisen suddenly found himself with nothing to do.

"???"

Kaisen's life at Hogwarts afterwards can be described as extremely boring.

As usual, he went to get out of class, ate, slept, occasionally taught Neville alchemy lessons, and went to the Hogwarts kitchen to have private lessons with the Hufflepuff wizards.

Time passed day by day, and Merlin finally put on his white lace pantyhose.

Christmas holidays are coming, it’s snowing in Hogwarts, and the Hogwarts Express magic train at Hogsmeade station once again cosplays as a steam train and enters the station.

Kaisen stood in front of the French window in the alchemy office and looked towards the station in the distance.

Originally, Neville was planning to stay at school this time, but he was called back by a letter from old Lady Longbottom.

Originally, Neville had invited Kaisen, but was rejected again.

And this time there are some real legitimate reasons, such as going to find Lupin, or to uncover the specific location of the Chamber of Secrets.

All in all, this Christmas I am free again.

Next, I just need to find a reason to postpone next year's Christmas... Well... maybe I don't even need to find a reason.

Under Dumbledore's governance, Hogwarts has many talented people and beautiful places. Last year, Quirrell appeared, this year, a basilisk appeared. It would be absolutely unacceptable if nothing happened tomorrow.

You don’t even need to look for reasons specifically, just wait and see, and the reasons will come to you.

After watching the Hogwarts Express leave the platform, Kaisen put on his coat and walked towards Dumbledore's office.

Because he had been idle for several weeks, he only now remembered that Dumbledore forgot to give him Lupin's address when he asked him to find Lupin.

Although England cannot be said to be big, it is not something that can be measured by foot.

"Pile of cockroaches."

The gatekeeper statue moved aside, and Kaisen walked up the stairs to the door of Dumbledore's office and knocked politely.

"........................"

..............................

"No one?" He was a little confused, and teleported directly into Dumbledore's office and went straight to the wine cabinet in the corner.

After taking a few bottles of fine red wine and putting them into his ring, he sat directly in Dumbledore's chair.

"Ah...it feels so good. Is this the principal's privilege?"

"You could say that," said one of the portraits hanging on the wall of the principal's office.

"Hmm........was this the chair you used when you were the principal? Or did you purchase it from somewhere?" Kaisen asked with his eyes closed.
