Dumbledore? He knows nothing about MC alchemy.

"What's wrong?" Kaisen asked.

"I never thought you would end up like this." Dumbledore said with a smile in his eyes.

"Clam?"

"He is an alchemical puppet. As the greatest alchemist in all of England, you didn't realize it?" Dumbledore teased.

Kaisen's eyes widened a little. He looked at Neos, then at Dumbledore, and then he looked at Neos in circles.

"Is this a fucking alchemical doll?" he asked confusedly.

"You've become a little too proud of your position and have forgotten the basics of alchemy. The transformation of matter, turning mercury into gold and alchemical materials into flesh and blood are the basis of alchemy. And this Neos is obviously an alchemical puppet." Dumbledore explained.

"I am too embarrassed to face anyone now." Kaisen murmured in despair, looking at the ceiling.

"...Well, don't worry, I will help you keep this secret." Dumbledore said.

"In fact, this is just a small matter. I... as an alchemical puppet, he must have an organization that stores memories... give him to me." Kaisen quickly adjusted his mentality and spoke again.

"That's true, but unfortunately, it's too late. On the way you brought him here, he probably destroyed his memory. He used the method that the body fears the most... high temperature, just like a child with a fever, you know." Dumbledore shrugged.

"Oh...our clue is gone." Kaisen sighed and sat down on the sofa weakly.

Chapter 283 Hmm

"Think positively. At least we have now identified an enemy of Hogwarts. He is the kind who is hiding in the dark and ready to strike at any time." Dumbledore sat next to Kaisen and comforted him softly.

But Kaisen ignored it and suddenly fell into deep thought. Soon he raised his head and spoke.

"...The problem is... I suddenly remembered something. Alchemy can create objects that are almost in perpetual motion, which can also be understood as life. Of course, in the broad sense of life, the kind of life that flowers and plants are. However, this kind of low-intelligence life may be able to use specific programs to perform various magics, but it should be difficult to make it use magic like the Confusion Spell."

Seeing this, Dumbledore added, "At least there needs to be an operator... or Hogwarts can just have a second one. After all, there are quite a few more outsiders at Hogwarts this year."

"Who could it be? We'll just have to wait until Severus brews enough antidote for Polyjuice Potion. But I can only say that this situation isn't very useful. As I said, there are a lot of outsiders at Hogwarts this year..."

"Having pulled out one nail, Tom can easily nail another one seamlessly." Dumbledore gave a pessimistic answer.

"We can't just leave it like this, right? How can you guard against thieves for a thousand days? Besides, we don't even know who the thief is right now, so there's nothing we can do to prevent it." Kaisen said helplessly.

"What I mean is that Neos is now an alchemical puppet, another hidden Death Eater. We need to find him and monitor him, but we can't pull him out, so we have to let him live under our surveillance."

"Otherwise, when Tom wants to drive another nail into the flesh of Hogwarts, the only ones who will be hurt are the young wizards of Hogwarts and other innocent people... After all, they need an identity to use the Polyjuice Potion, and the owner of this identity will only end up dead under their power and means." Dumbledore explained.

"You're right, Dumbledore." Kaisen nodded. "Then do we still need to use Polyjuice Potion?"

"We need to find a time when all of us are not sober, such as what you are best at... find a time when the whole Hogwarts will have a hangover tomorrow morning." Dumbledore said poetically.

".................I suddenly think this is a good idea." Kaisen said dryly, and at the end he couldn't help laughing out loud.

After leaving the principal's office, Kaisen teleported back to the small battlefield in the Forbidden Forest. Since he entered the magical world, he had not had many serious fights, but the ones he remembered most seemed to be in the Forbidden Forest.

There is something to be said about the height of this place.

Sirius also pulled Lockhart out of the wood with great difficulty. He was now considering whether to send him to St. Mungo's or bury him in a hole. Which of the two options was better?

But Lockhart was soon saved because Kaisen took out a bottle of bright red potion from his pocket and poured it into Lockhart's mouth.

Soon Lockhart's chest began to rise and fall again, and his dilated pupils regained their luster.

"How is it?" Kaisen asked, squatting beside him.

"pain..........."

"This is a small matter. Just drink another bottle." Kaisen took out another bottle of life-restoring potion and fed it to Lockhart. After two bottles of potion, Lockhart was able to sit up by himself with the help of Kaisen. Seeing this, the latter decided to go all out and took out another bottle of life-restoring potion.

After the third bottle, Lockhart could even walk, run, and jump.

"Thank you very much this time. Although you didn't take action this time and you became a sitting duck for the enemy, I still have to thank you." Kaisen patted Lockhart's shoulder and said.

"It's okay...it's just...I never realized before...that Hogwarts is so damn scary." Lockhart said, covering his pounding heart.

"Well, let me take you back. By the way, this matter must be kept secret, understand." Kaisen said as he used the force field to take him back to St. Mungo's, and returned to the Forbidden Forest a minute later.

"Won't he tell about that?" Lupin asked.

"He deleted that part of his memory, right in front of me," Kaisen explained. "But what do you do now? Your boss is dead. Did they see you?"

Lupin shook his head. "Fortunately, I had foresight. No one knew Neos and I were together. By the way, what did Dumbledore find out from him?"

"Uh..." Kaisen's old face turned red unconsciously when he said this, but he soon felt relieved and said bluntly: "Neos is an alchemical puppet. He can destroy his own memory storage, so...it's useless." Kaisen spread his hands and said helplessly.

"Wouldn't all our efforts be in vain?" Sirius sighed as he sat on the ground.

"Not entirely, at least Hogwarts has one less enemy..." Kaisen stopped talking here. As for the fact that there is a high possibility that there is another Death Eater or more Death Eaters inside Hogwarts, he did not intend to continue.

Things are accomplished through secrecy, so it is always better to say less in this situation.

"That's... not bad. What about Neos?" Sirius asked.

"Maybe it was eaten by the giant eight-eyed spider in the Forbidden Forest. Who can say for sure?" Lupin shrugged indifferently.

"Then I'll go check on Harry again and then I'll retreat... Forget it, how can I not retreat? I want to stay here and guard him." Sirius's map of Yan State was the shortest that Kaisen had ever seen, almost so short that it couldn't even cover the hilt of a knife.

"Please feel free to do so. I suggest you go talk to Dumbledore first. Maybe he can approve a dormitory for you." Kaisen said casually.

"I can already enjoy that kind of beauty. I will take Harry to find every secret passage in Hogwarts!" Sirius cheered.

“..................................”

“..................................”

Chapter 284: Pretend to be a human being in front of outsiders!

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

Kaisen found the sign that said Sirius and dogs are not allowed in the corner of his office and put it at the door.

The reason...

Because Dumbledore refused to give Sirius a room.

The latter even shamelessly came to the front of Kaisen's office to ask for a doghouse.

"So it's really not possible?" Sirius asked pitifully as he stood outside Kaisen's office and looked at the sign next to it.

"Obviously, yes." Kaisen said without any mercy.

boom!

".........................Fuck you."

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

"No, I finally have a chance to rest today." Kaisen said to Dumbledore who came to give out tasks.

Dumbledore, who seemed to have an exclamation mark above his head, smiled strangely and sat down: "If I had any other choice, I would never come to you."

"Oh, I understand. You come to me because you can't find anyone else." Kaisen suddenly started to speak unreasonably as if Lin Daiyu was possessed.

Dumbledore sighed, took out a small bottle of water from his pocket and moistened his throat. Twenty minutes later, Kaisen teleported to Diagon Alley and appeared in Ollivander's wand-making shop.

"Oh, you came to pick me up. It's been a long time since we last saw each other," said Ollivander.

"If I don't come today, we will still meet in a while...because our thesis is almost finished." Kaisen found a stool and sat down casually as if he was meeting an old friend, waiting for Ollivander to pack up.

"You guys? Although I know you may not like to hear it, I still think that your students' contribution to your thesis is very low. If you can take back the fame you gave them, at least you will definitely be the president of the England branch." Ollivander said.

"Isn't that a professor's job?" Kaisen explained with a shrug.

"Okay, how do we get to Hogwarts? Portkeys or something? As far as I know, you don't seem to have any talent for ordinary spells." Ollivander finally finished cleaning up the shop.

"I think the world is a huge alchemy, so we can rely on alchemy to do all kinds of great things. For example, alchemy can replicate various kinds of magic to a certain extent, including Apparition." Kaisen stood up and explained, and then the force field wrapped around the two of them. The next second they came directly to the alchemy office in Hogwarts.

Ollivander was stunned for a moment after regaining consciousness, then he looked at Kaisen who was already sitting on the sofa. "Before, I only had a simple guess about the size of your office based on the letters you and Dumbledore wrote to me. Then today, I saw your office... My vocabulary is not enough to express my shock in a non-swearing way."

"Oh, then you really have a strong idol image. I thought you never swore before." Kaisen stood up and poured Ollivander a glass of wine. "Moisten your throat. This is the way we treat guests at Hogwarts."

"You haven't been at Hogwarts as long as I have. How come I didn't know about this kind of hospitality?" Ollivander asked puzzledly.

"Because you were still a minor back then."

Before Kaisen could finish his words, the crystal ball on his desk lit up red.

"what does that mean?"

"It means Dumbledore is here to urge us. Let's go to the Great Hall." Kaisen said as he once again wrapped Ollivander in the force field, and the two of them left the alchemy office directly.

Firstly, Kaisen had great distrust in the old wizard Ollivander's driving skills, and secondly, he also had great distrust in the old wizard's health.

If he comes here in good health but ends up running away and dying, you will be guilty of a great sin.

"I thought you would take me directly to the Great Hall." Ollivander said in a daze.

"You might want to wander around the corridors of Hogwarts, but if you don't want to, we can just go there."

"Then let's take a walk." Ollivander looked at the furnishings in the corridor, which were no different from when he was in school, and the smile on his face never faded.

Of course, it's not that the appearance hasn't changed at all. At least the stone statue in the school has become an iron golem.

"I have a good memory. Almost everyone who has seen me twice knows this incident. You should know it too, right?" Ollivander suddenly asked as they walked.

"Apparently yes."

"So actually, if necessary, for example, when I miss Hogwarts or my student days, I just need to immerse myself in my memories, and I can see scenes that are almost exactly the same as now. But when I set foot here again after such a long time, I found that there is still a big difference between reality and memory." Ollivander said with emotion.

"Like what?" Kaysen asked.

"The biggest difference in terms of realism is that you are all living people, not NPCs."

"uh-huh."

The two chatted casually, with Ollivander doing most of the talking and Kaysen listening, occasionally adding a comment, and soon the two arrived at the auditorium on the first floor.

Dumbledore saw the two of them coming and quickly stood up to greet them.

Seeing this, Kaisen consciously distanced himself from Olivandra.

However, what was different from what he expected was that after welcoming him, Dumbledore walked towards Kaisen, and for a moment there was a feeling of fatherly love and filial piety.

Of course, Kaysen is the father.

In contrast, Dumbledore used a cunning look to emphasize to Kaisen that he must maintain his idol image in front of his old friend.
