Dumbledore? He knows nothing about MC alchemy.

The four little ones began a long...exercise.

"I should bring my broom next time," Harry muttered.

"I think... that makes sense."

"What's the matter? You accidentally knocked Lockhart stupid and asked me to save him?" Snape asked Kaisen while sitting in a chair.

Kaisen touched his chin and said little, while Dumbledore beside him looked a little embarrassed.

He called Snape here because he wanted Snape to give Lockhart some truth serum so that he could use it to search both body and soul with his Legilimency.

But now I have confirmed who that person is. In short... there is no point in Snape coming here.

".........Don't tell me that I came here for nothing." Snape looked at the silent Dumbledore and said.

"Of course not. We just went to the principal's office to talk about it."

In this way, the four little ones finally approached the desk panting, and then Dumbledore Apparated away with Kaison and Snape.

"....Are they kidding us? Making fun of us?"

"It was definitely Snape's idea."

"Although...but...I agree!"

The other side...

"The secret of Voldemort's immortality has been discovered... a very evil alchemical creation... a Horcrux." Dumbledore said as he sat in his chair.

"So that's how it is. As long as we find that Horcrux..." Snape nodded.

"I don't think Tom will just need one Horcrux. One Horcrux isn't enough to turn him into that half-human, half-ghost appearance." Dumbledore shook his head.

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

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

Kaisen and Snape looked at each other, then simultaneously turned speechless expressions towards Dumbledore, obviously dissatisfied with the Riddler's behavior.

"Bridget Wenlock discovered a magical number," Dumbledore explained.

"7? He made seven Horcruxes?" Snape asked.

"I can only say that it is possible. This is my judgment based on his personality. If he chooses to make more than one Horcrux, he probably won't choose to make them casually. His arrogant and twisted personality cannot accept anything that is not magical." Dumbledore nodded.

“…How many do you know now?”

"One of them, one of his notebooks."

"where is it?"

Kaisen shook his head. "Lockhart picked up the notebook and was then possessed by Voldemort. I found him and suppressed him in my office. Then Voldemort's soul must have suddenly left Lockhart's body. I searched Lockhart's body and his office, but I don't know where the notebook is."

"A Horcrux, a soul fragment, it doesn't even have much magical power except for bewitching people, how did it disappear?" Snape frowned.

"That idiot Lockhart followed Voldemort's instructions and infused his magic into the notebook," Kaisen explained.

".....What a complete idiot indeed." Snape said sarcastically.

Chapter 87 Myrtle

After a long while, Kaisen left the principal's office and reappeared in the Alchemy Office.

Lockhart, who was sitting in the corner, pulled the creeper head off his head and sent him away.

Next are four little wizards...

Well, they are surprisingly well-behaved. The four little wizards sat on the sofa, each holding a novel placed under the coffee table and reading it.

As Kaisen sat down in his seat, the four little wizards finally turned on their phones. Neville was still sitting on the sofa calmly, while the other three little wizards all looked at Kaisen.

"...what?"

"Professor, I want to learn alchemy!"

This time, Kaisen didn't waste time talking about anything unnecessary, nor did he explain anything superfluous to them. Instead, he took out three red stones that were slightly larger than the ones Neville had during the day and placed them on the desk.

"Light it up, and I'll consider you a pass... Of course, it has to be lit to a respectable degree."

The three little wizards quickly picked up their own redstone and tried their best to pour magic power into it.

Neville watched helplessly as his three friends almost each held a red stone slightly larger than their own, and the light was even brighter than his own.

Then Professor Kaisen started to lie openly: "Well... not very good. If you force yourself to learn alchemy now, you will easily get hurt. But I am still very happy to help you lay a solid foundation."

As he said this, he bent down and found a few alchemy notebooks under the desk.

"Go back and take a look. If you plan to sign up for my class next year, I think you will need it." Kaisen gave each of the four little wizards a copy.

Even Neville, who came to class early, had it.

"Then professor, we probably just can't really get started with the practical exercises right now, right? What if we're just auditing?" Hermione asked.

"In fact, there's no need for auditing, because for now I won't be lecturing, but rather using a more inhumane method."

"Inhumane?" Hermione was a little confused.

Then the four of them received four more runic textbooks. To be honest, this book was visibly thicker than the Oxford Dictionary and bigger than the benches in their auditorium.

"Oh my god." Ron looked at the big book in his hand in confusion, which could kill someone out of the blue.

"Hmm..." Kaisen looked at the watch on his wrist: "It's almost curfew time, aren't you going home now?"

The four little ones looked at the office door in the distance.

"Can we sleep here tonight?" Ron asked.

"Well... of course not. I have to go out tonight." Kaisen shook his head.

"So the professor also goes on night walks?"

Kaisen knocked Harry's head with his knuckles. "How can the professor's business be considered a night patrol? I'm just patrolling the castle as normal."

"Oh..." Harry suddenly realized: "If you are the one patrolling the castle tonight..."

"You could give it a try... maybe even use that invisibility cloak of yours and see if I can find you."

"Oh, okay." Harry shrank his neck, and soon the four little ones walked towards the office door in the distance.

Kaisen directly teleported to the abandoned bathroom on the second floor of the castle.

He reached out and knocked on the door. "Hello, Ms. Myrtle...? Or maybe a classmate? May I come in?"

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

There was only the gurgling sound of the sewer inside.

Kaisen knocked on the door again.

"Who are you?" A sharp voice came from the bathroom.

"Kasenhith, the Alchemy Professor at Hogwarts."

"Oh...I know you, come in."

Kaisen pushed open the bathroom door and walked in. He looked at the translucent gray-white ghost sitting on a toilet in a daze.

"Should I call you Ms. Myrtle or Classmate Myrtle?"

"Do I look old?" Myrtle's voice suddenly became sharp.

"Of course not, I'm just expressing my respect." Kaisen shook his head quickly.

"Oh... stop talking nonsense. No one in the whole school respects me, and I don't deserve your respect. After all, I'm not outstanding, not pretty, not smart... no..."

"Why do you think so?" Kaisen asked.

"Do I need to figure it out myself? I just need to stand in front of a stranger, and the answers will come out of his harsh mouth." Myrtle floated towards Kaisen.

"For example, you look at me. What kind of person do you think I am?"

Kaisen raised his head slightly, as he always did when looking at others.

【Magic】【Soul】【Death】【Void】

"........A kind person." He spoke quickly.

"Kind? Why do you think I'm kind?" Myrtle asked in surprise, as if she had never thought that this word would be used to describe herself.

"Based on your description, the attitude of the young wizards at Hogwarts towards you should not be considered good, but I have rarely heard of you playing pranks or saying bad things to hurt others at Hogwarts. Although ordinary ghosts can't pull off pranks like Peeves, they can still suddenly appear and scare people, or chase and curse them."

"But you endured insults you shouldn't have endured, yet you didn't vent any of your feelings. Perhaps at most you just hid quietly in this bathroom...waiting for your emotions to calm down. How can that not be considered kindness?"

There was a rare hint of flesh color on Myrtle's grayish-white face.

"Perhaps you're right... Could you elaborate a little more?"

"These are all easy to say. You just haven't discovered your own strengths, such as wisdom. You are a Ravenclaw, a Ravenclaw chosen by the Sorting Hat and Ms. Rowena Ravenclaw. You can completely become the person you want to be, instead of letting others find the strengths that you have overlooked." Kaisen comforted.

"Oh... thank you... but I'm still ugly, I still wear glasses, and I'm a crybaby." At that moment, Myrtle felt a little better, but soon, her mood became depressed again.

"Come on, isn't that what all teenagers do? At least from my perspective as an adult, it looks good. Wearing glasses isn't shameful. I wear glasses too."

"It's normal to cry. I had a student last year named Carsley. Of course, she has graduated this year. She also likes to cry. She wrote to me a while ago and said that she had joined the Department of Magical Law Enforcement at the Ministry of Magic."

Myrtle's eyes lit up as she looked at Kaisen.

"I know her, she's a good person."

Kaisen wiped the sweat from his head calmly.

It's really hard to deal with adolescent children.

Fortunately...I still have some talent.

Chapter 88: Which would you choose: a tire that tastes like cake or a cake that has the texture of a tire?

"You are such a gentle person... I almost want to come back to life and take your class." Myrtle slowly retracted her body into the toilet, leaving only her head exposed.

"Thanks for your trust, really."

"You are very polite. By the way, why did you come here to see me? I don't believe that anyone would have the time to visit a ghost." The two pigtails swayed like water plants in the water.

"My question is a bit offensive, and you might get angry when you hear it."
