Dumbledore? He knows nothing about MC alchemy.

Dumbledore shook his head: "That's not it. What I want to tell you is...Gellert told me this."

"...you say."

"Gellert said you wanted to repair my relationship with him?" said Dumbledore.

"Why does he tell you everything... No... You are not Dumbledore." Kaisen looked at Dumbledore with a puzzled look.

Dumbledore shrugged helplessly: "Okay." Then almost in an instant he turned back to his original appearance - Grindelwald.

"How did you recognize me?"

"Although Dumbledore is sometimes openly flirtatious, to be honest, he really wouldn't tell me such private matters. After all, although he never said it explicitly, I can tell that he always treats me like a child."

"He always thinks I need to be taken care of and watched over. If he doesn't know about me for a while, he'll think I'm up to something big."

"So when you first showed up in my office by some unknown means and were surprised by my behavior, I didn't doubt you at all. Dumbledore treated me like a child, so when he found out I had learned the Killing Curse, his first reaction was definitely the same as yours: surprise, anger, and then asking me who taught me."

"You acted well in that regard. You really understand him well enough," Kaisen explained.

"I may be the person who knows him best now... Then how did you know that he was me in disguise?" Grindelwald nodded in understanding and then asked.

"Like I said, would you reveal your...relationship history to a child?" Kaisen shrugged.

"Good reasoning."

Kaisen was very pleased with the compliment. Although he was slightly inferior to some talented monsters, and even suffered a dimensionality reduction attack, that was only between him and Holmes.

Is it shameful to lose to Holmes? Not shameful.

But compared with the wizards whose logical ability is a little awkward, Kaisen also got a taste of being a boss.

"Okay, so since you're not Dumbledore... you're okay?"

"Actually, there is... Did you know that Albus is not an only child?" Grindelwald said.

Kaisen shook his head.

"He had a brother who owned the Hog's Head, and a sister named Ariana, who passed away, and that's how we started to drift apart."

"So...what happened to you, Ms. Ariana...?" Kaisen asked.

"This is what I want to say. That day, Albus, his younger brother Aberforth and I had a fight at Dumbledore's house. I don't know whose spell suddenly hit Ariana who came downstairs to see what happened. It was because of this incident." Grindelwald explained.

"Very...whose spell is that?" Kaisen said hesitantly.

"It's not mine. The spell I cast was blocked by Aberforth. The spell Aberforth cast at that time was a protective spell." Grindelwald sighed.

"So, Dumbledore..." Kaisen murmured.

"He was blinded by one of my flash spells, so he released a magical power without any attributes. This is his common method to deflect other people's spells." Grindelwald continued.

"So you're saying these are..."

Grindelwald took a deep breath. "This is a hurdle he and I can't get over. It would have been fine before, but now I've... let it go... If he asks, please tell him I was the one who cast the spell."

"But you didn't cast that spell." Kaisen frowned.

"A dark wizard who did all kinds of evil, known as the Dark Lord, killed an Obscurus, and a brother killed his sister. Which of these two things do you think is easier to accept?"

"You are his favorite professor, and I hope you are worthy of his favoritism."

Grindelwald said with a smile.

Kaisen sighed, "...Okay."

[This is a beautiful secondary creation by the reader Yun Duo Pai. I originally wanted to tag her directly, as I'm already following her. However, since I have an early exam tomorrow, this chapter is scheduled for release, so I had to write her name. I'll tag her tomorrow morning, or if Yun Duo Pai pops by, I'll leave you a fantastic review.]

Chapter 162 I personally recommend starting with zero frame

"But why don't you tell him all this yourself?" Kaisen asked.

"From the time I was imprisoned in Nurmengard until I showed up at Hogwarts, we hadn't seen each other for... forty-seven years, or maybe forty-eight years. He had been avoiding me, you understand," Grindelwald explained.

"It seems that Dumbledore also has some guesses about Ms. Ariana's death. The reason why he doesn't want to see you is because he doesn't dare to hear the definite answer from your mouth." Kaisen nodded in sudden realization.

"But I remember the portrait in the headmaster's office said Dumbledore would go out every Christmas. I didn't know why before, and after I learned about you, I thought he went to see you."

Grindelwald shook his head. "He's a heart of stone. How could that be possible?"

".........What about Aberforth?" Kaisen asked again.

"No one in the Dumbledore family shirks responsibility. Although Aberforth is not smart, he is not so stupid as to blame his own mistakes on his brother Albus... But I heard that their relationship is not very good now..."

"That's normal. For Aberforth, not pointing his finger at Albus and calling him the murderer of his sister is already very gentle."

Grindelwald sat on the sofa with his legs crossed. The long conversation had made him so engrossed that he waved his hand and a bottle of wine flew out from the wine cabinet next to him.

"Do you mind if I take a souvenir?"

Kaisen rubbed his chin in confusion. "You mean you came here empty-handed, and you want me to give you a gift when you leave?"

"This is an exchange. I will use the security loophole in your office in exchange, for example, it cannot prohibit the instantaneous movement of the portkey." Grindelwald said with a buzz and disappeared.

The corners of Kaisen's mouth twitched, and he decisively opened the restriction of the enchanted Ender Pearl.

It was understandable that Dumbledore came to his office. As the headmaster, he had the privilege of following the rules of Hogwarts. It was understandable that he was not affected by the apparition ban of Hogwarts.

But old man Grindelwald also followed suit and made a key to his own office door, which is too fucking abstract.

Besides, couldn't he just tell me directly if there was anything? Why did he have to beat around the bush and pretend to be Dumbledore?

Kaisen thought about it seriously for a while, and decided that since he was free, he should find a mine and throw Grindelwald in to dig. He would be obedient after two months of digging.

Of course, the greater possibility is that the mine was blown up into the sky by old man Grindelwald, along with the people, machinery and ore.

"Eh... they are all old magical monsters." Kaisen sighed, took out a bottle of wine from the wine cabinet and poured himself a glass.

Ding dong...

The crystal ball on the desk lit up, and Kaysen leaned forward to light it. The four little wizards from Gryffindor… perhaps objectively speaking, they couldn't really be called little wizards anymore. By the time their third year arrived, Harry and the others had grown up.

However, he still called the seventh-grade students little wizards, so he still had no intention of changing his name.

Soon the four of them drove the boat to the office area. It was then that Kaisen noticed the interesting seating arrangements of the four people. Harry and Neville were in the middle, with Ron and Hermione sitting on both sides.

They always smile when talking to anyone, but when they look at each other, there is a hint of dislike between them.

"Wow, what happened to Hermione and Ron?" Kaisen asked.

"Well... obviously, there was a quarrel... It seems to be because of Hermione's pet Crookshanks and Ron's pet Ben. These two pets are a cat and a mouse, so... uh huh." Harry spread his hands helplessly and said.

Sirius, who was taking a nap on the second floor, suddenly opened his eyes. Although he didn't hear anything, to be honest, he really needed to go downstairs now... It was an intuition.

Harry watched Sirius walk down with his tail wagging, and was just about to open his arms to give him a happy hug, when he saw Sirius walk straight towards Ron, lying on Ron and sniffing left and right.

"Tom and Jerry, to be honest, your pet configuration is quite classic." Kaisen said with some amusement.

Sirius, who was checking whether Ben the Mouse had hidden on Ron this time, sniffed even harder.

"Yeah, Benban is so scared of that stupid cat that he dares not leave the dormitory. He shivers in the matchbox I made for him every day. Now he doesn't even dare to go to the cafeteria." Ron complained bitterly.

"That's a cat Ron, it's the nature of cats to catch mice," Hermione retorted.

"I know it's a cat's nature to catch mice, but as Crookshanks's owner, can't you restrain him? I put my BenBan in my hand and he still wanted to pounce on me. If you don't want to bring a cage for your cat, please bring a leash for your cat... OK?"

Ron finished speaking in one breath and looked eagerly at the bottle of wine on the coffee table. He was now thirteen years old, which was the time of adolescence. Human cubs at this stage were disliked by everyone and liked to come up with new tricks.

so.....

"Want to try it?" Kaisen saw Ron's desire and said with a smile.

"Is that okay?"

"For you little underage kids, I strongly don't recommend you try this." Kaisen took the wine glass away, turned around, picked up a teacup and poured himself a cup of tea.

"Okay, Professor." Harry and Ron looked a little disappointed. It seemed that they were quite curious about the taste.

After the five of them had a harmonious opening chat between teacher and student, Harry, Neville, and Ron tacitly sat aside and gave the stage to Hermione to perform.

And Hermione lived up to everyone's expectations and started from zero frame: "Who the hell is Professor Trelawney?"

Kaisen almost spit out the tea from his nostrils when he was halfway through drinking the tea.

"Ahem, Hermione, be civilized, be civilized, if you have something to say, just say it."

Hermione calmed down and let out a long breath: "Professor, I should have listened to your advice. I shouldn't have been so stupid as to go to that damn Divination class."

Kaisen nodded. Originally, he was not very good at comforting others, but after coming to Hogwarts and being a teacher for three years, he knew very well what to do when he encountered a young wizard who was out of control of his emotions.

Just don’t say anything and let the other person finish speaking first.

This can also be applied to listening to adults, of course, if the person on the other end is an enemy who wants to insult you...

I personally recommend starting with zero frames.

Both verbally and physically.

Chapter 163 Ron's anger will be troublesome, but not too troublesome

Hermione talked to Kaisen for nearly ten minutes. During this time, Harry and Neville were forced to move to other sofas to avoid the fight.

Only Ron, perhaps because he felt that if he avoided the attack he would be considered a coward, or for some other reason, still sat firmly on the same sofa with Hermione.

But Kaisen thought it was not the first thought, because Ron poured Hermione four cups of tea in the past ten minutes...now five cups.

Whenever Hermione was talking so much that her mouth was dry and she had to stop for a while, Ron would always push a cup of tea over to her at the right time.

"Thank you." Hermione always said thank you after drinking.

Ron continued to sit on the sofa with his arms around his shoulders, and did not respond, as if this way he could still maintain the aloof personality he had just conceived. However, whenever Hermione said she was thirsty, he would still pour the tea and push it over, then put his arms around his shoulders and pretend to be aloof without responding to her thanks.

Kaisen looked at Harry and Neville covertly, wanting to ask what was going on.

Harry gave Kaisen a look, he understood.

Ron being angry would be troublesome, but not too troublesome.

Kaisen nodded, obviously attributing this contradictory behavior to Ron's personality.

He knew the four Gryffindors very well. Hermione never hid her personality. She was smart, strong, kind, and sometimes a little bit sinister.

Harry's personality appears soft on the surface, and he smiles at everyone as long as they are not his enemies, but in fact he has the toughest temper. Everything needs to be discussed with him, and he will not turn back until he hits a wall. He is determined to rush towards his expectations, and will get angry if the result is different from his expectations.
