Dumbledore? He knows nothing about MC alchemy.

Kaisen was also the same, turning a deaf ear to what was happening outside and studying the syllabus for this semester.

"One of my research topics at the time was the possibility of using alchemical technology to transform the human body."

Only then did Kaisen look at Grindelwald helplessly and said, "Do you think that thing is attractive to me?" As he spoke, a mechanical arm slowly extended from behind him, picked up a glass of wine, put it to his mouth and took a sip.

"This thing can't be applied to ordinary people." Grindelwald shook his head.

"Yeah, that's true." Kaisen nodded. His own mechanical arm, mantis blade and hidden blade were all controlled by the power of his thoughts and the redstone signals deep in his nerves.

The most an average person can do is make a small hidden blade like Harry's and add an anti-weapon device. This is the only modification an ordinary person can accept.

"Don't you want to pass on your skills?" Grindelwald asked quietly.

"A normal person would like to transform himself into this half-human, half-ghost appearance." Kaisen shrugged.

"but?"

"But if we're looking for a successor..." Kaisen raised his head slightly: "Be detailed."

"That's a soul branch technology that allows a person's soul to radiate, like tree roots, using the branches of the soul to control various alchemical equipment. A person is like an alchemical factory running at full power." Grindelwald explained.

"Brain-computer interface?" Kaisen translated.

"what is that?"

"Nothing." Kaisen shook his head. He was no longer interested in plans like finding a successor. After all, mechanical ascension was something that most people could not accept.

Rather than popularizing robotic arms, the place that can truly promote the soul branch technology should be Hogwarts!

I did nothing for most of the summer vacation except digging holes and installing machinery under Hogwarts, waiting for the day when that blind enemy would invade Hogwarts and I would watch in confusion as Hogwarts stood up.

As for making Hogwarts stand up, it's very easy, just decorate the basement of Hogwarts with something awesome.

But it was difficult to control. His original idea was to have a large number of wizards control each system joint separately. But if the soul branch technology that Grindelwald mentioned was really that magical, he probably could really do it...

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

Kaisen suddenly realized that Hogwarts seemed to be heading in a strange direction.

"Then what do you need?" Kaisen didn't think that Grindelwald asked him to steal something just to steal something that would be useful to him but was of no use to him.

The so-called soul branch should be just an unimportant thing to Grindelwald, but it is very relevant to his professional expertise. There should be something else besides it.

"Indeed, I made a soul amplifier to facilitate my research on the soul... Do you know what that thing is?" Grindelwald asked.

"Of course I know. When performing delicate operations or magical experiments involving the soul, one must utilize some of the soul's powers, such as telekinesis and mental strength. This soul amplifier is a device that enhances mental strength... But I can make one for you myself? Why would you need to steal it?"

"I was young at that time, and in order to make it easier to study, I attached a piece of my soul to it... But don't worry, that thing is not a Horcrux. After I die, that soul will automatically peel off and return to me. But you can't let me be missing a piece of my soul while I'm still alive. Do I have any strange habits like Voldemort?" Grindelwald said with some shame.

"Couldn't you have gone back to get it when you were fired?" Kaisen said with a twitch of his mouth.

"At that time, I thought it was a good idea to leave a soul in Durmstrang, because I could still control that soul, and it could provide me with a lot of information. But since I entered Nurmengard, that soul fell into a deep sleep until now." Grindelwald explained.

"......." Kaisen listened to Grindelwald's bizarre actions and touched his chin helplessly. He originally wanted to touch his beard as well, but unfortunately, he had just shaved it this morning.

“..................................”

“..................................”

"Where's the address? Where's your soul amplifier... and your unfinished experiment?" Kaisen finally sighed and decided to help others...

...........The soul branch is a small head, a small head, and is not the main factor in helping.

"I remember that I did that research in the office of my then alchemy professor. I was later expelled, but the experiment should not have been continued by the professor at that time. However, the experimental data and results should still be in his office, including the soul amplifier. You should be able to find them in the storage room of the alchemy office." Grindelwald said.

"Hmm... the alchemy laboratory, or Durmstrang... Hey, I think I know the current Durmstrang alchemy professor. I can just write her a letter and ask for it openly."

"If it doesn't work, I can rub some gold. It won't cost much." Kaisen suggested.

"No, no, no. If you want to keep those things intact, you have to steal them. If they knew that there were Gellert Grindelwald's things in the storage room of the Alchemy Office, they would use Fiendfyre to plow through the entire storage room." Grindelwald shook his head.

"Uh, so I have to tell the truth, right?" Kaisen stood up and stretched. Then the mobile blackboard not far away slid over automatically. "Come on, draw a floor plan of Durmstrang. You should still remember it... It's a pity that my map can only depict the roof of Durmstrang, not the interior."

Chapter 253 Are you a dark wizard or am I a dark wizard?

"Do you want me to give you a plan directly? I don't think this is a good idea." Grindelwald shook his head.

"Do you want some kind of improvisation plan?" Kaisen frowned.

"Almost. Let me draw a map for you first. Durmstrang's alchemy office is in the east corridor on the second floor. You just need to go from here..."

Soon, Kaisen memorized the map firmly in his mind. He looked up at Delindover and asked, "What next?"

"Then just take this with you." Grindelwald pulled out another monocle from his pocket.

Kaisen reluctantly put the glasses on his other eye...

"Uh, I feel so dull." He casually summoned a mirror and complained helplessly.

"I think it's pretty good. By the way, this thing is not only a monocle that can communicate, it is also a door key. It is enough to just transmit magic power into it." The monocle made a subtle sound that condensed into a thread and reached Kaisen's ears.

"Oh, I really wish every magic school could have an airport." Kaisen sighed.

"This is a tradition at Durmstrang. Every wizard uses this thing when returning to school. Remember not to let anyone see it." Grindelwald warned.

"Yeah, yeah, I understand." Kaisen nodded, and the next moment he suddenly disappeared.

"...................Leaving out in the middle of the day? That's what young people are like..."

On the other side...

"This Durmstrang door-breaking key is too sensitive." Kaisen sighed helplessly as he appeared in the middle of a small forest.

"Wow wow wow wow, I thought this was your pride as a young man." Grindelwald's voice came from the monocle.

"Bullshit, what kind of door-breaking key is this? It can even be activated by the magic energy emitted from the human body."

"Maybe it's been a long time. This was given to me by the school before I was expelled from Durmstrang. But since you're here, just follow this... Just walk along the path and you'll see the castle." Grindelwald responded.

"OK." Kaisen rolled his eyes, then he sighed and walked towards the end of a well-trodden path.

Then he saw a dark Gaosong Castle... and a bunch of little wizards...

"What a damn key to break the door..." He sighed, cast an invisibility spell on himself, and then walked towards the interior of the castle in a swagger.

"After you walk through the gate, the nearest staircase is on your left. However, judging by the current flow of people, there should be a lot of people here. Be careful not to run into them. Otherwise, according to the tacit understanding among Durmstrang students, they might just give you a hard blow." Grindelwald continued to remind.

"Don't worry, I have a good plan." Kaisen said as he flew up and arrived on the second floor above the heads of the little wizards.

"Next is east... east..." Lai Song walked to a corner and took out a compass... However, the compass didn't seem to be pointing to the east... It seemed more like the direction of the orphanage where he had just arrived in this world...

"Your five o'clock direction...hasn't anyone taught you how to tell the directions?" Grindelwald said helplessly.

"I'm sorry, we don't learn this in school." Kaisen explained and walked towards the east.

"Haha, what a ridiculous Muggle school."

"Uh... Hogwarts doesn't seem to teach east, west, south or north either." Kaisen retorted.

"But they will teach me the way, a guidance charm," Grindelwald explained.

"Oh, thank you for the reminder." Kaisen said as he struggled to decipher the German text and soon found a sign for an alchemy office.

"How do you plan to get in?" Grindelwald asked.

"Just knock on the door, then push it open and walk in. This will be a prank." Kaisen said as he knocked and then pushed the door open and walked in.

hum!

A light blue spell flew towards Kaisen quickly, but fortunately he reacted quickly and dodged the spell by bending down.

"I forgot to tell you, this is Durmstrang's style. If a naughty little wizard dares to play a prank on the professor, or does it without the professor's consent, you will be rewarded with a curse even if you knock on the door." Grindelwald whispered.

"Um...it seems not all wizarding schools are like Hogwarts."

"The little wizards at Hogwarts...are not special...like little wizards. They are more like ordinary children."

"Wizards and ordinary people just have different professions. I know you are too old to change your mind, but could you please not say that in front of me?" Kaisen sighed.

"Well... maybe that's what Albus is wondering about."

"I think this is Dumbledore's greatness." Kaisen said as he walked into the office cautiously.

"This office is so small, is it really big enough for alchemy experiments?" Kaisen complained mercilessly.

"Is it possible that your office is too big?"

Kaisen did not respond to Grindelwald, but began to look around the alchemy office. Madam Rosmerta, the alchemy professor of Durmstrang, was repairing a small alchemy device in front of her while swearing.

"Where is the storage room in this office?" asked Kaisen.

"Don't worry, you have to wait until the professor leaves before going to the storage room." Grindelwald replied.

"Are you afraid she'll be alerted by the sound of the door opening?"

"if not?"

Kaisen touched his chin, and the next moment he pulled out an anvil and swung it directly at the back of Ms. Rostamer's head.

clang! ! !

As a crisp sound rang out, Ms. Rostamer felt a little sleepy, so she chose to lie down on her desk and take a short nap.

Grindelwald: "..................................."

"Where's the storage room?" Kaisen asked, picking his ear.

"...................................Are you a Dark wizard or am I a Dark wizard?"

Come on, come ...

Asking for gifts, family members!

Chapter 254 I'll show you a PPT

"Nonsense, of course it's you. Where's the storage room?" Kaisen asked.

"Um...right behind the desk, there are three gems under the desk. You need to press them down in a certain order. The order is different for each professor, so I suggest you..." Grindelwald heard two strange thuds before he finished speaking.

Knock knock.....

"Is this the storage room?" Kaisen asked as he knocked the wall twice with his knuckles, creating a 2m×1m hole.
