Hogwarts: I rely on MC to pretend to be an alchemy professor

Kaisen and Sirius looked at each other for about two seconds. Strangely, neither of them mentioned the matter. Instead, they ignored Neos naturally. After they walked away, they decisively teleported back to England. After finding some little wizards who were having a lot of fun in Diagon Alley, they went straight back to Hogwarts.

"Why are we suddenly back here? And why did Lupin fall asleep?" Ron asked, looking at Lupin who was sleeping soundly on Kaysen's shoulder.

"Because I'm safe enough. It's getting dark soon. Sirius and I need to discuss some things with Dumbledore. You may want to go play with Hagrid. We'll pick you up from Hagrid's place after we're done."

After Kaisen sent a few little wizards to Hagrid's Hut, he teleported directly to Dumbledore's office.

"Oh... do you know why I don't agree with your charged ender pearl?" Dumbledore said faintly.

"Why?" Kaisen, who appeared in Dumbledore's office directly by Ender Teleportation, had no self-awareness at all and asked shamelessly.

".....................Forget it, you must have something to do to come here to visit an old man like me." Dumbledore sighed helplessly.

"Yes, it is indeed something very important." Kaysen put Lupin on the chair, and then Sirius cast a counter-spell to wake him up, but not completely.

"It's us, Kaisen, Sirius, and Dumbledore is here too." Kaisen explained.

Only then did Lupin open his eyes blankly, as if he had just fallen asleep. He looked at the furnishings in the principal's office, and at the smirking expressions of Kayson and Sirius.

"I was going to ask for leave! What are you doing!" Lupin yelled and pounced on Sirius.

Sirius was instantly knocked to the ground by Lupin, and the two of them started fighting each other.

"Stop! Stop Remus, we have something important to do now!" Sirius said with a grin.

After a while, Lupin calmed down and sat back in his chair.

"We found that the director of the dragon farm in Romania, Neos, was a little strange..." Kaisen began to describe the strange things about Neos in a vivid way.

Dumbledore leaned back in his office chair and listened for a long time. After Kaisen stopped to clear his throat, he sat up straighter.

"Maybe he's just naturally emotionless."

"Do you believe this?"

"...We need you again, Lupin." Dumbledore pondered for a moment and looked at Lupin and said.

"What do you mean?" Lupin asked subconsciously, but he soon realized that some masters of the Imperius Curse or memory with superb skills can modify people's subconsciousness or even directly change their memories.

For example, a person may appear normal on the surface, but his or her memories have been completely dug out, and he or she has subconsciously mistaken the thief for his or her father... Although this is only a theoretical situation, it still has basic credibility.

At least it's not too outrageous.

"You mean I just have to wait until the Quidditch World Cup is over, I wait a few days or longer, and I pretend nothing happened and go back to the dragon farm, but I accidentally lost my memory of the time I disappeared, or I just tell the truth and say that I watched the Quidditch World Cup, because this could also be a false memory implanted in me by a fictional person."

"This way, even if Neos really has some problems, I can monitor him closely?"

Dumbledore nodded: "That's it..."

At this moment, Kaisen seemed to suddenly remember something. He suddenly raised his hand, revealing the Death Eater mark on his wrist.

"Did you paint this?" asked Dumbledore.

"Yes, Sirius and I both drew it. We originally wanted to scare Lupin, but Lupin didn't see it. However, when I raised my wrist to talk to Sirius, Neos saw it," Kaysen explained.

"So Neos saw the mark of the Death Eaters but didn't stop you. On the contrary, he was so weird... But if this Neos is also a Death Eater, it makes sense." Dumbledore said dimly.

Lupin and Sirius thought about it for a moment and realized that it was true.

"Then if that's the case, wouldn't I be exposed? He only needs to ask Voldemort or his Death Eater companions or kidnap me to find out what's going on." Lupin frowned.

"Don't worry. Tom doesn't trust anyone. Similarly, his Death Eaters won't ask him about everything. That would be dangerous for the Death Eaters. Neos saw two Death Eater companions but didn't go up to say hello foolishly. This is enough to show that he is a veteran Death Eater. Of course, all this is based on the premise that our suspicion is the truth."

"But like I said, a veteran Death Eater wouldn't be so reckless."

"I see............." Lupin exhaled: "I accept this mission, close surveillance is quite simple."

"In fact, it's not that simple." Kaisen said as he pulled one of Lupin's hands. The mechanical arm behind him suddenly stretched out and took a drop of Lupin's blood.

Lupin was confused: "I thought I was hallucinating before, so where did you get this mechanical arm?"

"It's been less than a day since he returned from Romania." Dumbledore said sarcastically.

"Please don't pay attention to the details." Kaisen said as he took out an Ender Pearl, then smeared Lupin's blood on the pearl, and then took out a teleportation device that had not yet been activated. Dumbledore recognized it..........

The day Kaisen made this teleportation device was the first time he knew what kind of supermodel this half-baked alchemist who came back from the Muggle border was.

"You need something... that can break at any time and anywhere, and it would be best if it would only break when you are hurt." Kaisen touched his chin.

"Ahem." Sirius took off the ring on his finger. "The Black family's treasury is quite rich. This is a magic ring that can be activated by magic power. It can instantly transform a large area of ​​virtual life with life around itself to guard against the Killing Curse. However, it will shatter after the resistance is over."

"Isn't this inappropriate?" Kaisen slapped his thigh and said.
