Dumbledore? He knows nothing about MC alchemy.

"Then who do you think I should let teach him?" Dumbledore sighed. He was once again being taught a lesson by Kaisen like a grandson.

"Can't you find someone Harry likes and who also likes Harry, such as Lupin, Sirius, or just go to the Auror's office and find someone who is better than Severus teaching Harry." Kaisen said, leaning back in his chair.

"Why don't you just let me do it myself?" Dumbledore said speechlessly.

"If you don't have time, you can go on your own. If you have time... To be honest, I think you are quite leisurely now. Look, you can spend the whole morning studying the water-drop stone beast downstairs." Kaisen said with a beaming face.

"Alright." Dumbledore sighed and said something sharp: "It just so happens that I really don't have anything to do these days, so I'll leave this difficult task to Gellert. He has even more free time than I do."

"But before that, you need to remove the magic from Harry's amulet. The practice of Occlumency and the constant intrusion of memories go hand in hand."

"And the magic in Harry's amulet will prevent him from making any further progress," Dumbledore explained slowly.

"Yeah, I will." Kaisen nodded and was about to get up.

"By the way, don't tell Harry too much. The moment Harry's amulet loses its effect, Voldemort may be able to obtain information from Harry's head continuously. Don't say anything until he learns the brain-blocking technique." Dumbledore said.

"No explanation?" Kaisen asked.

"No explanation is enough!"

[I can’t sleep because of insomnia, so I’ll write another one.]

[Please give me gifts and praise! ]

Chapter 359 Grindelwald's Language Skills

Kaisen returned to his office and took a look at his schedule. His next class would not be until tomorrow morning.

I have more than enough free time. I glanced at the school's public course schedule again to make sure that the fifth-year Gryffindors are not busy at the moment.

Kaisen left the office and went to the auditorium to find a random Gryffindor wizard: "Classmate, can you please call out a senior named Harry Potter from your college and tell him that Professor Kaisen is waiting for him in the office."

The young wizard, who looked to be in his early second year, nodded and said, "No problem, Professor."

Kaisen smiled and nodded and returned to the office. After a while, he saw Harry slowly gliding towards him in a small boat.

"Professor, do you have something to talk to me about?" Harry asked doubtfully.

"Well, there is something going on. For your own safety, you need to learn a sophisticated spell. Of course, you can also say it is magic. The term is casual." Kaisen nodded and stood up.

"What?" Harry asked curiously.

"Dumbledore has instructed us not to tell you too much about this before you learn the spell, as it might lead to leaks. So please don't be too curious. Of course, after you learn the spell, feel free to ask anything you want to know...if Dumbledore wants to tell you."

As Kaisen spoke, he put his hand on Harry's shoulder. The next moment, the Enderman Field enveloped the two of them. When they opened their eyes, they appeared outside the Defense Against the Dark Arts office.

Kaisen reached out and knocked, and soon the door opened.

"Oh... Albus just told me about Mr. Potter. Please come in." Grindelwald welcomed the two in.

He wasn't as nagging as Kaisen. In other words, he revealed much more information than the others: "Because Voldemort cast a special curse on you, which allows him to read your memory sometimes, you know this?"

Harry blinked blankly.

"It's... um... when your scar hurts." Kaisen responded to the confused Harry.

"Yes, every time your scar hurts, it means that Voldemort's curse has taken something from your brain," Grindelwald explained.

"But...ever since Professor Kaysen gave me this, I haven't had that feeling anymore?" Harry took out the beacon amulet from his chest with one hand, and scratched his head with the other hand, not quite understanding.

"That's a two-way block. Voldemort can't see your memory, and you can't see Voldemort's memory. You should know that Arthur Weasley was injured, right?" Grindelwald asked.

Harry nodded. "Ron was in class this morning when he was suddenly called away. When he came back, he found out it was Uncle Arthur..."

"Yes, that's right. If you learn the brain-occlumency technique, your soul memory and Voldemort's will be reconnected. Voldemort will not be able to obtain our information from your memory. However, you can use this curse to provide us with a steady stream of information about Voldemort. What a great thing is this?" Grindelwald held Harry's shoulders and said step by step.

Kaisen stood in the corner of the office, what could he say?

Compared to Dumbledore who treats everyone as NPC, Grindelwald does a very good job in this regard.

At least both of them made Harry learn Occlumency. What Dumbledore did was put Harry and Severus, two people who disliked each other, in the same office and used force to force them to act according to his will.

Grindelwald, on the other hand, proceeded step by step and patiently, explaining the cause and effect of each matter clearly, as well as the various advantages and disadvantages.

There may be some concealed information or rhetoric...but speaking only of the feasibility of the plan, Grindelwald is really a dimensionality reduction attack on Dumbledore.

Harry listened to Grindelwald's sensible and emotional speech, and slowly sorted out what was happening to him.

Let's not make it so complicated...let's just keep it simple.

Only by studying the brain defense techniques that Grindelwald mentioned can he return to the front line of the fight against Voldemort.

Seeing that Grindelwald had boosted Harry's enthusiasm for learning Occlumency with just a few words, Kaisen couldn't help but give Grindelwald a thumbs up implicitly.

The latter gave him a smug look.

Kaisen raised an eyebrow, walked towards Harry, and simply touched the beacon amulet with his hand to turn off the soul isolation function.

Harry instantly felt a sharp pain in the wound on his forehead, as if he should have felt the pain but it had been saved until today.

But soon, the stinging sensation gradually subsided, as if it had never existed.

"My scar hurt again just now. Is it because of Voldemort?" Harry asked.

"Perhaps... But if you learn Occlumency, you won't have that problem." Grindelwald slowly pushed Harry into his seat. "Learning Occlumency is about using your willpower to resist Legilimency."

"This is not the only way, but it is the most efficient and fastest way. The only drawback is that it will be very painful for you. I want to tell you all these things in advance." Grindelwald sat in front of Harry and said slowly.

"I can do it, Professor!" Harry said firmly.

Grindelwald nodded and looked at Kaisen again.

The latter nodded and slowly left Grindelwald's office, closing the door behind him.

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

Time flies, and Christmas is here in the blink of an eye.

Strictly speaking, Hogwarts was not very peaceful during Christmas this year. After all, Voldemort was active outside Hogwarts. Although he and his Death Eaters had not done anything big yet, they still cast a terrifying cloud over the whole of England.

There was nothing Kaisen could do but carefully wrap Christmas gifts for the students in the hope of making them a little happier during this holiday.

Chapter 360 Christmas Surprise?

Soon, Kaysen wrapped up the gifts for the three major Hogwarts colleges except Slytherin and sent them out in batches by owls.

And it’s Slytherin’s turn for the gift...To be honest, the gift has been prepared early, but I haven’t really thought about whether to give it or not.

Because of canceling the Gedil family's account, Slytherin had a strange little fear of himself.

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

It's basically the same level as Gryffindor hiding from Snape.

"So if I give them a gift, will they actually accept it? Will they think it's some Middle Eastern alarm clock or something?"

Kaisen murmured, looking at the last remaining stack of silver-green gift wrapping paper. He was silent for a while, but finally decided to give it away!

He bent his sore fingers and continued to fold the gift wrapping paper. If only his robotic arm was still there... it would be much easier to fold the wrapping paper.

The previous mechanical arm was completely destroyed when fighting Voldemort, and the new one...

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

He has been waiting for the last batch of robotic arms because they were too fragile, so he plans to use netherite to make this batch.

However, due to the special properties of Nether Alloy, its shape cannot be changed directly. It can only be assembled slowly using tiny blocks. In addition, the skeleton also needs to be upgraded.................

It's so troublesome to even talk about this kind of thing...

The actual research progress is still at the PPT level...

emmm..................

In this way, the busy Master Kaisen worked for about two hours before he packed all the remaining gifts and sent them out.

After finishing these things, he picked up the paper version of the PPT of his new robotic arm, which was like a plan, and teleported to the Black house.

During the turbulent times when Voldemort was rampant, not only did the Order of the Phoenix huddle together for warmth at Black House, but even other wizard gathering places, such as Godric's Hollow, Hogsmeade Village, Diagon Alley, almost all the wizards in England huddled together for warmth.

For example, when Kaisen just came back, he found that there were two new members in the Black Mansion, Mr. and Mrs. Diggory. But seeing that these two were there, Cedric should be chatting with other young wizards upstairs.

Sirius, who was sitting on the sofa pretending to be cultured by reading a newspaper, cheered when he saw Kaisen return: "Now that everyone is here, can we play that game?"

Kaisen, who had just returned, was confused: "What game?"

"Remus learned a game called Dungeons & Dragons from the Muggle world. It feels like playing chess on a big map," Mrs. Weasley explained.

"Well... England has that game... No, that game? You kids?" Kaisen was speechless, like a bored adult mercilessly mocking their gaming taste.

After all, he is not a child, he still has very important things to do, such as recasting his mechanical arm to improve his combat effectiveness, so that he can directly destroy that Bi Yang's brain basket when he meets Voldemort next time!

Young people, you should do something serious!

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

As Mrs. Weasley stood up and stretched hard, she slowly left the sofa. Kaison, who was just doing some serious work, saw that no one was coveting the sofa, so he quickly stood up and sat on the sofa that Mrs. Weasley had just been on.

This scene caused Sirius and Lupin to roll their eyes.

"Didn't Professor Kaysen say he was going to study some serious business? Why is he here?" Sirius rolled his eyes and talked trash.

"It's that... I'm tired and need to calm down... Well, I just saw you guys having so much fun and I was a little envious, I want to play too..." Kaisen was still stubborn for a while, but soon he told the truth with a completely aggrieved look on his face.

"Haha! That's right, brother!" Sirius and Lupin laughed at the same time, stretched out their hands and high-fived Kaisen.

"By the way, why didn't I see Dumbledore today? What was he busy with in the kitchen?" Kaisen suddenly asked while playing.

"In the kitchen. He and Grindelwald have been staying in the kitchen since he arrived this morning. He said he wanted to make some of their special dishes for us, and he won't let anyone in." Mrs. Weasley responded while playing cards with the Longbottom family.

Kaisen simulated the scene in his mind: Dumbledore and Grindelwald in the kitchen... If Grindelwald could cook, he would probably believe it.

The old man had been in Nurmengard before, and it didn't seem like there were prison meals or deliverymen there every day, so he had to cook for himself.

But what was Dumbledore doing in the kitchen?

As a fully automatic trouble-making machine?

Even the ingredients can’t be carried!

Thinking of this, Kaisen couldn't help laughing, which made many other people at the table a little confused. It was just a game, there was no need to laugh so uncontrollably, right?
