Dumbledore? He knows nothing about MC alchemy.

At least it's not too outrageous.

"You mean I just have to wait until the Quidditch World Cup is over, a few days or even longer, and then pretend nothing happened and return to the dragon farm. But I accidentally lost my memory of the time I disappeared, or I can 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 draw 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 Death Eater's mark 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 quietly.

Lupin and Sirius thought about it for a moment, and 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 know what's going on." Lupin frowned and said.

"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. That Neos saw his two fellow Death Eaters but didn't foolishly go up to greet them. This is enough to prove that he is a veteran Death Eater. Of course, all this is based on the premise that our suspicions are true."

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

"I see..." Lupin exhaled. "I'll accept this mission. It's a simple one, close surveillance."

"It's actually 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 mind 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 preferably something that will 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 actively activate magic power. It can instantly transform a large area of ​​living virtual life around itself. It is used to guard against the Killing Curse. However, it will shatter after the resistance is over."

"Isn't this inappropriate?" Kaisen said, slapping his thigh.

Realism doesn't suit me, I'll just paint abstractly.

It's drawn like a microphone.

Asking for a gift

Chapter 238 Don’t laugh, you two

Kaisen took the ring and placed it casually on the table. Just when Sirius and Lupin were confused, Dumbledore took out his wand and duplicated it into two.

The next moment, Kaisen handed the main ring to Lupin, put the copy ring into the teleporter box and turned on the switch.

The last step is to put Lupin's ender pearl into the sparkling water: "Done!"

"Is it that simple?" Lupin asked in surprise.

"Oh, you know alchemy." Kaisen said proudly.

"Oh... This is my first time as an undercover spy. I don't have much experience before." Lupin said somewhat relaxedly.

"If you really don't know what to do..." Dumbledore said halfway before realizing that in this small office...Kasen and Lupin could certainly be talked to, after all, they were reliable enough, but Sirius...

He simply changed his words and said, "I'll give you some books later."

"Thank you, Professor." Lupin smiled.

After they finished speaking, everyone put on their coats. Dumbledore sighed and said, "I don't like holidays. Although it's a bit selfish, the headmaster's office is still a bit too lonely."

"Um...you can come with me. The new house I bought is quite big." Sirius said.

"Bullshit! Don't listen to his nonsense. Does he have anyone to accompany him this holiday?" Kaisen dragged Sirius and Lupin and teleported to Hagrid's Hut.

At this time, Hagrid was setting up a barbecue grill in the yard, and there was a mountain of meat piled up on the side.

"Oh Hagrid, do you want a barbecue?" asked Sirius.

"Obviously, and he even left chairs for us, didn't he?" Kaisen, who had returned to his office and gotten two bottles of good wine the moment he saw Hagrid set up the barbecue grill, replied.

"..........Aren't you going a little too fast?" Lupin asked in surprise.

"I'm fine. Any problem?" Kaisen walked into Hagrid's hut again, took out a few glasses and poured wine into them. He sat on a small stool like a few other children and waited for dinner.

"............I'll go help Hagrid, Sirius..." Lupin was halfway through his words when he saw Sirius shamelessly sitting on the stool...

"What's the problem?" Sirius asked confusedly.

"...It's nothing, just wait and eat." Lupin obviously didn't want to say any trash talk during this happy time. Soon he and Hagrid marinated all the meat... About three seconds after they finished...

"Sirius, come here and work! And Kaisen, are you a child?" Lupin, who was extremely unbalanced, yelled at the two of them... Of course, it was more likely that he was using this opportunity to vent his emotions about being pranked just now.

"No need. In fact, Remus, you don't need to come over. I can handle all of this by myself! You just sit there and eat!" Hagrid said cheerfully.

"I knew Hagrid, you are still the same Hagrid!" Sirius said excitedly.

Hagrid seemed a little embarrassed...

After all, he had said before that he would tear Sirius in half... But judging by Sirius's behavior, he probably didn't hear it. This did have some benefits...

On the other side: "Tsk tsk tsk... Hogwarts... The world is going downhill... Traditional virtues... Respecting the elderly and loving the young..." Dumbledore, who was enjoying the breeze in the observatory, clicked his lips as he looked at Hagrid's hut in the distance.

"Because they didn't invite you?" Grindelwald appeared behind him at some point and said softly.

"It's like Muggle children playing together. Parents naturally can't join in," said Dumbledore.

"That's no problem. I've booked a restaurant. Let's go." Grindelwald shrugged.

"it is good."

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

Late at night, Privet Drive...

"Sirius...can you please stop acting crazy when you're drunk! You are a human being now, not Bruce!" Kaisen said to Sirius who was staggering and shouting.

Woof woof woof...

Kaisen looked at Lupin helplessly and said in a state of collapse: "And Lupin... when you invite the dog to dance, remember to cast an Animagus counter-curse first! You won't even know if there's a ghost in someone else's house!"

"...........So, professor, do you have to walk on the railing?" Neville asked as he looked at Kaisen walking like a cat on the fence of the yard again.

"This is different..." Kaisen shook his head: "I am just an ordinary alchemy professor. I don't have the power as strong as you to walk in the dark void with my flesh body..."

Neville sighed, "Well, all three of them are drunk."

"Yeah, if they each took two cephalexin tablets at this time, Voldemort would laugh his nose off." Hermione also complained.

Soon, they arrived at Sirius's house. The little wizards took great pains to tuck the adults into bed before they finally breathed a sigh of relief.

"We should have listened to Hagrid and just stayed at Hogwarts for one night."

"Yes, if Professor Kaysen hadn't said that there was a huge black ship above Hogwarts that was going to capture wizards and take them away to be burned as firewood..."

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

the next day.......

"Last night...how did we get back?" Kaisen asked while sitting at the dining table and eating mechanically.

"Oh... Professor, you brought us back by Ender Teleport... Although we teleported to the roof next door, they were so scared that they thought it was an alien invasion..." Hermione said softly.

"Uh, why does my body hurt so much?" Kaisen said with a gritted teeth.

"Professor, you feel pain because you fell from the roof and then you said the ground was a dark void. So you walked on the wooden fence all night, fell down after taking a few steps, and then the so-called dark void hurt you. Then you climbed up again, fell down again, and climbed up again, over and over again..." Hermione continued to complain.

On the other side, Lupin and Sirius showed strange smiles, and then Hermione frowned again: "Don't laugh, both of you, and listen to me..."

Chapter 239 Departure

Lupin and Sirius, who were laughing just a second ago, stopped laughing instantly.

"Let's talk about Lupin first. You found a random Bruce on the street late at night and said you wanted to practice dancing. And Sirius... Forget it, let's not talk about Sirius." Hermione suddenly remembered something in the middle of her sentence and slowly stopped talking.

"Great............." Sirius breathed a sigh of relief.

Harry sighed helplessly. It would be very embarrassing if Sirius knew that he got drunk and cried in his arms for most of the night.

After the meal, everyone started packing their luggage... Well, actually it was just a bunch of Hermione's books and snacks for the rest of the people, including Kaisen.

After all, for a modern person who has been exposed to modern sports and various entertainments, it is too abstract for him to see a bunch of various flying balls doing irregular circular motion in the sky.

In comparison, it is better to hold a big bag of snacks and eat as much as you can, after all, it creates a good atmosphere.

"Ahem, it's not just about eating, it's also about preventing Death Eaters from rioting." Dumbledore also informed Lupin of this difficult responsibility, and asked him to keep an eye on Kaysen and Sirius to make sure they didn't do anything fancy.

"Don't worry about that." Kaisen nodded in response.

"When I bought the ticket, they also gave me a key to the World Cup venue... and an Apparition map? Which one should we choose?" Sirius said, taking out a blue glass ball.

Kaisen didn't want to make any choice. One option was to hook his belly button with an iron hook, and the other was to flatten himself into a round shape and stuff it into a pipe.

"There's nothing we can do. The wizards who invented Apparition and Portkeys were undoubtedly great, but their successors, including us, are obviously not that great. There haven't been any breakthroughs in these two spatial magics for such a long time." Lupin comforted.

"Hmm, let's give it a try." Kaisen sighed and reached out to touch the glass ball door key.

Soon everyone else followed suit, which was a bit stressful for the poor glass ball, after all, it was just a ball, not a depression mushroom.

The next moment, a slightly abstract force that made people subconsciously feel uncomfortable and fear acted on them. When they opened their eyes again, they found themselves in a sparse grove.

"Let's go. I don't understand the other wizards' train of thought. Why would they buy a Muggle tent instead of living in the three-bedroom, one-living-room magic tent?" Sirius said first.

"That's new! Camping tents give me a feeling that mattresses can't... although they are indeed uncomfortable." After complaining, Kaisen suddenly remembered something. Normally, every camping area should have a place selling tents: "Wait... where did they buy the Muggle tents?"

"No, they're a Muggle merchant." Sirius finally realized what was happening: "They're Muggles? This won't do. This won't do..."

The two looked at each other, and soon Kaisen walked over and stood around the Muggle shop to look around. Logically speaking, places where a large number of wizards appeared should have Aurors and memory masters sent by the Ministry of Magic. The former two were to prevent those wizards from eating and drinking and starting to make trouble, and the latter was to keep an eye on the Muggles at all times and prepare to forget them.

Sometimes they also bear the responsibility of protecting Muggles. Although this responsibility should be the responsibility of the Aurors, compared with the large number of wizards, they may not have the energy to do these things.

After all, wizards may sound nice, but their personal qualities are really poor. They are different from the wizards in Western fantasy novels. The latter really need great wisdom and perseverance to achieve success, while the former rely purely on bloodline.
