Dumbledore? He knows nothing about MC alchemy.

"............Yes, next we need to find my research materials and soul amplifier. I remember the research materials were packed in a black suitcase, and the soul...what are you doing?"

Kaisen accepted everything he saw and carried it back to his office through the ring in his hand. He also responded as if it was natural: "Get your things back?"

"...Actually, you don't need to take so much." Grindelwald said awkwardly.

"Well, since we're here, we might as well bring some local specialties." Kaisen said without stopping his hands. Soon, the entire storage room, including the shelves, were put back. Just when Grindelwald thought that Kaisen should come back anyway, he looked at the office outside the storage room.

"Tsk tsk tsk... This book... What's wrong with me? Why haven't I seen this style of alchemy before?" Kaisen casually took an alchemy book from the bookshelf and took a puzzled look at it, then naturally used the Ender Ring to take it back to the office.

Then there's the entire bookshelf, the little ornaments on the desk, the sofa that looks really comfortable, and the tapestry on the wall looks great too. Wow! The carpet is pure Pegasus hair!

Soon, Ms. Rostamer was the only person left in her office except for a chair and a desk.

Of course, there were some who survived, for example, she didn't touch any of the homework that the little wizards gave her to correct.

"Hey, I'm such a good person." Kaisen sighed, and with a buzz, he instantly returned to his office in Hogwarts.

Grindelwald was sitting on the sofa that Kaisen had picked up from Durmstrang, looking at him strangely.

That look felt a bit like... a parent looking at their own useless child.

"Tsk tsk tsk, didn't you ask me to steal things? Why do you have that expression?" Kaisen asked.

Grindelwald sighed: "I asked you to steal things, not to move... Never mind, it's my fault too." Grindelwald sighed and stretched out his hand, and Kaisen returned the portkey monocle.

"Have you found that bit of your soul? If not, I can help you look for it." Kaisen said as he looked through his monocle at the batch of things he took from the storage room. More than half of them were more or less stained with soul.

"That won't work. It's my soul after all, and I can sense it to some extent." Grindelwald said as he found a MINI version of the soul amplifier. After picking it up, he seemed to be smelling flowers or stinky tofu. Kaisen didn't know.

In short, I took a deep breath in ecstasy...

"That thing has so much dust in it, won't you accidentally breathe it into your lungs?" Kaisen asked...

"My lungs are itchy... but it's nothing serious." Grindelwald said as he rummaged around on the floor a few more times, found the experimental materials on the soul branch, and placed them on Kaisen's desk.

"That's it," Grindelwald said as he was about to board the boat and leave the office.

"Well, bye. If you have any questions, I can ask you." Kaisen waved his hand and opened the suitcase. The next moment, he saw a lot of German text.

"............Mad, Grindelwald!"

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

Grindelwald had no classes in the afternoon, so he had no choice but to stay in Kaisen's office to translate the materials, and he had to translate them into English no matter what.

Kaisen went straight downstairs to the alchemy classroom. He looked at the little wizards under the podium with a smile. Now was the time.

It's time to give them a little industrial shock.

He first asked all the little wizards to gather together, and then placed wooden blocks one by one on the podium like a magic trick, and then gently hammered them with a small wrench.

With a pop, a small gear popped out.

"So... Professor, isn't this alchemy? How did it become transfiguration?" Cedric asked in confusion.

"In order to teach you this lesson, I specially borrowed a projector from Professor Snape to show you the PPT." Kaisen said as he took out a projector from under the podium and took out a very retro film.

"Everyone, please look carefully. This is a documentary about the industrialization of automatic assembly lines that I found specially in the Muggle world. It took me a long time to find someone to convert it into film. Don't waste my effort." Kaisen said as he stood at the back of the classroom and pressed the switch of the projector.

The video is very short, from the world's earliest devices in which humans borrowed natural forces, such as using stones to crush bones, to sails, water wheels, levers, and animal power.

Later, humans finally lit up a dazzling technology tree again: boiling water.

In contrast, factories are becoming increasingly efficient, relying on human labor, animal power, drive shafts, steam engines, generators, etc.

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

"So...what's the use of this?" Morgan asked in confusion.

"Didn't you notice that in these documentaries about changes in productivity that I just showed you, there was a powerful force that never appeared from beginning to end, Mr. Arthur?" Kaisen asked.

"Um...you know me. I'm not good at riddles." Arthur Morgan spread his hands helplessly.

"Magic, I've been investigating for a long time. In the entire wizarding world, no matter which country's wizarding society has a proper automated workshop. I've found a few simple reasons."

"First, ordinary Muggle artifacts, such as large energy machines like steam engines and generators, may mutate due to the intrusion of magic. Even the unconscious transformation or vanishing spell of the magic itself can have a significant impact."

Chapter 255 Why should I say um?

"Even explosions. After all, we all know how mischievous wizards' magic can be. Hogwarts has so many young wizards like you. Your scattered magic can even give rise to something as weird as Peeves. So it's perfectly reasonable for you to have terrorist attacks happen every now and then while you're at work."

"After all, that kind of thing happens all the time in the Ministry of Magic."

"Secondly, using powerful magic, we can also create something similar to an automated assembly line. However, I've noticed that many sophisticated alchemical equipment and potions are very sensitive to magic, so relying solely on magic is not advisable."

Kaysen wrote these two points on the blackboard.

"And now, I've found a new method that can free wizards' hands. I originally called this method mechanical power, but I don't think this name is particularly magical, so I call it magic transmission."

Kaisen took out a few small gears and said, "We just need to assemble them like this..."

"Oh, and don't forget to give them some little details."

Boom...Boom...Boom...

"What happened?" Professor McGonagall, who was speaking to Dumbledore in the headmaster's office, asked in confusion.

"Oh, who knows? Although I don't know what happened, I know exactly who made this noise." Dumbledore shrugged.

On the other hand, Kaisen returned to the office after class and looked at the information that Grindelwald had helped translate. He felt envious. He didn't know how many languages ​​the old man knew. He couldn't compare with him in this aspect. Because of his Chinese foundation in his previous life, he was almost regarded as a mute in the first few years after he traveled through time as a child. Fortunately, hard work can make up for lack of talent.

This also reflects Kaisen's daunting language talent, which is basically no different from Shet's... Even until now, he only knows... two and a half languages.

Before he could sit down and take a closer look at the information about the Soul Branch, a little wizard stood in front of him.

"Find a chair and sit down, Arthur... uh, I always feel your name is a bit strange, because the gentleman from the Weasley family is also called Arthur." Kaisen looked up and said.

"You can call me Morgan, I'm not picky." Arthur shrugged.

"Then let's go with Arthur. You two didn't show up at the same time anyway, so what's going on?"

"Professor, what's the use of that alchemical doll you demonstrated to us in class, which was made of gears and could understand human language, without losing magic power, and could do repetitive and precise work?" Arthur asked directly.

"Automation? Actually, it doesn't require that level of sophistication. I was just showing off my skills to you. To actually use it, you only need to let it do one or two very simple things." Kaisen answered casually.

"I mean, Professor, why does the wizarding world need such high productivity? This is what I really wonder." Arthur asked.

"Well, they are still useful. For example, the wands you use contain a device called tracers. They are made from the wood fibers of undead trees. The magical power of these wood fibers fluctuates widely. Before they are processed, they can cause power plants thousands of miles away to malfunction for no apparent reason. That's why they are used as tracers and are one of the means by which the Ministry of Magic monitors young wizards like you."

"Extracting this trace thread is also extremely difficult. Its magical radiation range is too large. Muggle mechanical equipment cannot use it, and we can't use magic directly. Because although the trace thread's magical radiation has a wide range, its intensity is low. If it is directly impacted by other magical forces, it will be completely useless and become ordinary wood fiber."

"So, to make that thing, people have to use knives to cut it into small wooden strips, and then use hammers to smash them into fibers. This so-called magic transmission does exactly that."

"It should help people make ends meet, giving them time and energy to write poetry and paint, rather than trying to get into high-end stuff right away...that's useless."

After Kaisen spoke for a long time, he picked up the water glass and took a sip to moisten his throat.

"In that case, those who originally made a living by making trace silk fibers would have no way to make a living, right?" Arthur asked.

"The truth is so cruel, that's why we have to improve ourselves... and in fact no one makes a living by making this thing. I have been to Ollivander's workshop. That is his apprentice's job... the kind that does not pay." Kaisen replied.

"...If I want to build a factory after I graduate...Professor, what kind do you think it should be?" asked Arthur.

"You may not build a factory, maybe you will find a farm to grow mangoes." Kaisen said subconsciously.

"Huh?" Arthur asked in confusion.

"Oh, nothing, nothing. Your name sounds like another friend of mine." Kaisen waved his hand.

"Which Weasley?"

"No, his last name is Morgan too."

"Okay Professor........what about my question?"

"That depends on how well you learn. For example, if you have Severus's skills in brewing potions, you can even use this thing to mass-produce Felixir... I think." Kaisen did not forget to put on a piece of armor when he said the last sentence.

"Professor, why do you speak so unconfidently?"

"Because I don't know Potions...My first year at Hogwarts, your Professor Snape told me not to devote my limited energy to Potions, so it's obvious that I don't have any talent." Kaisen shrugged.

"So...Professor...can I understand that learning magic transmission is not very useful?" Arthur asked.

"If everyone makes progress, it's collective progress, not individual progress. It's just that there's no one to compare you with, but in fact, you have indeed made progress." Kaisen subconsciously took a sip of chicken soup.

"Okay...so I can only make sure I don't fall behind..." Arthur leaned back in his chair and sighed.

"I can only say that you are better than most people." Kaisen stood up and encouraged.

"Uh-huh......................Why should I say uh-huh?"

Asking for gifts, family members!

Chapter 256 Hermione's Madness

After using a bowl of chicken soup to send Arthur away and tell him to get out and study hard, Kaisen also returned to his life of going back and forth between class time and study time.

He naturally squeezed his meal time into class time.

Well...the little wizards have no objections.

He also roughly understood the technology behind Grindelwald's soul branch. As a civil engineering senior who had audited medical courses, he could still explain the principles behind it.

Before that, we need to give it a name first. Let's give the result of this great plan to make Hogwarts stand up a code name, which is called Hogwarts Titan.

The Hogwarts Titan can be thought of as a human body without a brain. Kaisen's original conception required many wizards to individually control a joint or even a specific piston. These wizards could be thought of as the brains of the Hogwarts Titan.

But it’s different with this soul branch. The soul branch acts as the human nerves. Only one wizard is needed to control the entire Hogwarts Titan, which is also very efficient.

Like right now...

"So, professor, what is the use of this thing?" Led by Kaisen, the fifth-year wizards went from street to street in Hogwarts, laying all kinds of alchemical rails.

"You can understand the necessary reinforcement and specific energy transmission for Hogwarts. When this amazing work of mine is completed, you can even write down what you did today on your resume." Kaisen said as he directed the placement of the various alchemical rails.

"By the way, Professor, do we really not need to take shelter for a bit... We're almost at Professor McGonagall's office..." another little wizard also said.

"No need. This project has been endorsed by Professor McGonagall. Just work with confidence. I will add some cool things to your alchemy professor's office later." Kaisen said with a smile.

"But Professor, aren't you the professor of alchemy?"
