Dumbledore? He knows nothing about MC alchemy.

"Since you're so polite, I can forgive you this time. Ask."

Kaisen nodded: "How did you die?"

Myrtle seemed relieved when she heard this question, and Kaisen only heard a long tail sound.

"The question isn't offensive. To me, death is like a second life, like a birthday, something to be celebrated."

"Then I'm lucky, I picked a good question."

"Well... when I died, an annoying guy laughed at me. I don't know where she is now. Maybe she married a troll, or maybe she choked to death while eating a bagel that day. Anyway, I wish her a bad life with my magical heart."

"I was crying here that day, right here in this bathroom, until I heard a boy's voice. It was quite nice, deep and charming. I thought the owner of that voice must be a handsome guy."

"It's just a shame it wasn't the right place. This was the women's restroom after all. I turned around to warn him, and then I died."

Kaisen touched his chin...

"that's it?"

Myrtle nodded. "That's all... not all. At that time, I also saw two yellow-orange... what looked like the eyes of some giant creature."

"This clue is very useful. Also, how did you die? What did your body look like?"

"Just like that, so peaceful and scary, like I was asleep. I would rather my death was ugly, because that would scare that guy more. If I died as horrifyingly as the Bloody Baron or Sir Nick, that guy would never be able to hold on!" Myrtle said with some regret.

"That guy?"

"That's the annoying guy I mentioned at the beginning who laughed me into this bathroom."

"That guy is..." Kaisen asked curiously.

"I won't tell you her name. Maybe she has already died in some unknown corner. I just hope that her name can completely disappear from this world." Myrtle said viciously.

"Hmm...I understand."

"Can I ask you why you ask that?" Myrtle asked again.

"To find out the truth about your murder, find the murderer, and protect the young wizards now." Kaisen explained.

"Well...you are a good person, and what you have done deserves this face..." Myrtle smiled and said while staring at Kaisen.

"Oh...thank you for the compliment."

"You're welcome. It's like you're praising me. If you want to hear this kind of blatant compliment, just come here."

"Thank you, I will if you need me."

After getting the answer, Kaisen said goodbye to Myrtle very politely and warmly, looking back every few steps. Of course, apart from saying goodbye, he did not cast any other extra glances on any other place in the bathroom.

After all, the sign outside the bathroom said "Female", so it was unreasonable for him to come in alone and scan every inch of the bathroom carefully like a camera... It was a bit perverted.

After returning to the office, Kaisen pulled a small mobile blackboard from the classroom downstairs and placed it in the corner of the office area. He wrote two key points on the front with chalk, one of which was the huge yellow eyes, and the other was the intact body.

Draw these two key clues that can be confirmed on the blackboard, and the other clues found later can be fitted into them like a formula. It is quite convenient, but the neighbor was full of contempt for this stupid method.

".................If only that guy was a wizard, I wouldn't have to sit here staring at the damn blackboard..." Kaisen muttered as he leaned back in his armchair.

the next day..................

"get out of class is over." After saying that, Kaisen picked up a few pieces of draft paper on the podium, knocked off the four corners, and then casually folded a thick paper airplane and threw it into the trash can.

After teleporting, the Enderman appeared directly at Hagrid's villa on the edge of the Forbidden Forest.

If you were to look for the person in Hogwarts who knows the most about magical beasts, the first person that comes to mind would definitely be Professor Kettleburn, the professor of magical beasts.

However, this professor has a quality that makes people can't help but admire him. Out of seven days a week, he teaches five courses for five grades in one day, and spends the remaining six days traveling around the world.

So much so that.............can't be found.

But it doesn't matter. If Professor Kettleburn can't be found, there is still a second person who knows about magical beasts.

"Boom boom boom!"

A moment later Hagrid, wearing an apron, opened the door.

"I'm baking some cakes, come in and try them. Of course, I would be happier if you could take some away." Hagrid quickly welcomed Kaisen in.

Kaisen sitting on the sofa...

Chew chew chew.......................

"Hagrid, do you know anything about tires?"

"I know, what's wrong?"

"Which do you prefer, a tire that tastes like cake or a cake that tastes like a tire?" Kaisen asked.

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

"Have you really started researching?"

Hagrid's face turned red after hearing this, and he calmly took the cake away from the coffee table.

"Maybe something else, rock cake."

"I want some more milk."

"Of course, I won't forget the milk."

Soon, after changing to a set of tea and snacks, Kaisen let out a long sigh. He couldn't help but think of the three-headed dog from last year. Maybe the big guy's teething toy was the cake made by Hagrid.

Not to mention the taste...at least it tastes good.

"Well, the new year has begun again... To be honest, I think even the sunshine on this Black Lake has become a lot brighter." Hagrid sat on the sofa and sighed as he looked out the window at the Black Lake in the distance.

Chapter 89 Neville Learns to Be Smart

"Well, Hagrid, do you know what kind of magical creature has huge yellow eyes and can kill people instantly without destroying the body?"

Kaisen said as he took a sip of his tea strategically.

"Yellow eyes, they can kill instantly without destroying the body. I only know of two, the venomous beast and the basilisk. They can both kill with their eyes. Of course, the victim has to look directly into their eyes. Why are you asking this?" Hagrid scratched his head.

Kaisen touched his chin and finally decided not to tell Hagrid about the return of one of Voldemort's Horcruxes. Instead, he used another matter to prevaricate the matter: "I know there's a ghost named Myrtle in the abandoned bathroom on the second floor of the castle. I'm investigating her cause of death."

"Oh...uh...why did you suddenly start investigating her? Uh...I knew a little about this matter back then. Do you know how I was expelled from Hogwarts?" Hagrid said a little embarrassedly.

"Ok?"

"Let me make it clear first, I definitely didn't kill anyone. I was falsely accused, and the person who falsely accused me was... He was a big shot in the school back then. In short, he was a very famous person." Hagrid took a sip of black tea to warm himself up.

"It was he who falsely accused me back then. Myrtle Warren died in that bathroom, and the school launched an investigation. That person reported to the school that it was my Aragog who did it, but firstly, it promised me that it wouldn't hurt anyone, and secondly, even if we take a step back and it was really Aragog who did it, Warren's body would definitely not be so intact." Hagrid said viciously, biting the rock cake.

"Um...who is Aragog?"

"It's a giant acromantula, and it's in the Forbidden Forest right now."

Kaisen took a sip of black tea and recalled a specimen of an eight-eyed giant spider he had seen in Snape's office before.

emm......................

Voldemort's bringing the school's attention to the existence of the Acromantula may be the only good thing he did in his life.

"And then? Tell me more," he continued.

"Then, uh uh uh... that's it. The idiots at the Ministry of Magic didn't care about Warren's intact body at all. After all, the poor child was a Muggle-born, and his parents just knew there was a place for the wizarding world."

"The Ministry of Magic naturally won't investigate with all their heart. They just need to punish me as quickly as possible to put an end to this case, and then pretend to tell the wizarding parents of the young wizards that Hogwarts is safe again under the Ministry's investigation."

Hagrid said dully, leaning back in his chair.

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

"By the way, it's been so many years since this happened. Why did you suddenly think of investigating it?" Hagrid asked.

"Originally, I just wanted to find the monster that killed Myrtle, but now there is another reason. Do you want to always bear the crime of being a murderer?" Kaisen took out a small diamond pickaxe, knocked off a piece of rock cake, soaked it in milk and said.

"Oh..........thank you Kaysen."

"It's okay. You mentioned the venomous beasts and basilisks. Do you have any specific information about them? Or do you know any reference books about them?"

"I'll prepare a copy for you later."

"Thank you very much."

Hagrid leaned forward and patted Kaisen's shoulder gently with his palm as big as a palm fan. "I should be the one to say thank you. You are helping me through and through. I don't have as powerful magic as you, nor is my mind as quick as yours, so I can't help you with anything else. But fortunately, I know enough about magical beasts."

"You can't possibly go through the wind and rain in the castle to help me investigate the real murderer and clear my name while I hide in this house eating rock cakes and drinking hot coffee? Although I might cause trouble with other things, I can still do what I can."

"OK, I'm not doing this for you, or you're just incidental. I'm doing this for Myrtle, the victim, and the little wizards who are potential victims."

Kaisen wanted to pat Hagrid's shoulder, but there was a large coffee table between them, so he had to pat Hagrid's big head which was almost sticking to the coffee table.

"Um............."

"emmmm........................"

Kaisen rarely heard a slight tremor in Hagrid's voice, so he simply said nothing and left quietly.

After all, the boss is a big man, so he still has to save some face.

Back in the office, Kaisen picked up the chalk and wrote "Blascaris" and "Brassilis" on the blackboard, then stared at the blackboard.

After a while, he had no other results except that his eyes were sore.

Fortunately, I stopped reasoning for the time being. I put the chalk behind my ear and took out a bottle of grape juice [fermented version] from under the desk.

Just as he was choosing a wine glass from the cabinet, the red crystal ball on the desk suddenly lit up.

Kaisen pressed it casually, and the office door in the distance opened.

Neville learned his lesson this time. He rode a broom that looked like Harry's Nimbus 2000 and flew over slowly.

Although Neville's broom-riding skills are not as fast as those of the Quidditch students, it is still much better than running on foot.

"Hello, Professor."

"Uh-huh, are you coming to class? Or is there something else?"

Kaisen subconsciously wanted to pour Neville a cup, then suddenly realized something was wrong and quickly replaced it with a cup of black tea.

Neville sat down and took out a piece of parchment from his pocket and spread it on the desk.

"I designed this for Harry. As a Seeker, Harry is uncomfortable wearing both goggles and glasses, so I wanted to make him a pair of glasses that can block the wind and protect his eyes, and won't fall off."

Kaisen took a closer look at the parchment. It was more of a concept drawing than a design drawing. After all, it only contained a picture of round-frame glasses and a description of the effect.
