Chapter 609 Another Forbidden Knowledge

"Professor Deng...Moody, please be cheerful. We are on a business trip, not doing hard labor."

Andrew looked at Dumbledore, who had already taken the form of Professor Moody, and happily communicated with him.

The two are currently waiting at the airport to board the flight.

Although it sounds a bit strange, it is true - the plane is really useful. Although it takes a little time, it is much more useful than stacking door keys on top of each other.

Since we have already set off early, the delay in the flight is nothing.

"Minerva may still be there," Dumbledore lowered his voice, causing Andrew to freeze.

No, I'm going on a business trip in advance, Principal. Why does it sound like you're taking a vacation in advance?
But at this point, he could only stand on the side of Dumbledore - after all, it was he who took the initiative to discuss whether they could set out earlier. Although the professor agreed, there was no doubt that this was an act of interrupting the original arrangement.

But Dumbledore was genuinely happy—even the time the prosthetic leg went through security to check if it was a disguised gun didn't disturb Dumbledore's mood.

After the plane stabilized, Dumbledore didn't even pretend, his face was full of smiles, and he ordered all the desserts without any hesitation.

"Plane is pretty cool, Taylor. Are you interested in making one or replicating it?"

"Imitation?"

Andrew shook his head. "It's troublesome to keep such a big thing secret. We can't make it completely invisible. It won't pass the confidentiality law."

"So your plan is to make a longer pass track?"

"No plans for that at the moment, Professor."

Andrew shook his head. “I just had some strange ideas. I was thinking about the transmission function of some dreams and messy things.”

"That makes sense, but even if you don't have it, it won't hurt for you to apply for these documents."

As he spoke, he cast his eyes on the book in Andrew's hand, not surprised at all.

These books are another kind of forbidden knowledge in the wizarding world besides the dark magic, and have never been included in the Hogwarts library.

The making of portkeys, the principles of the Floo Network, the limitations and expansion of Apparition - although they may not sound related to dark magic, when combined with various spells to protect secrets, it is another kind of Azkaban curse in the wizarding world.

Especially the portkeys. Illegally manufacturing a portkey can allow the maker to immediately gain entry into Azkaban, but this book of dark magic in another sense was delivered by the Ministry of Magic itself.

“Any new ideas?”

"No, Professor." Andrew shook his head and said in a very low voice, "This is the first time I know the nature of the Floo Network... It's really incredible. It turns out that the Floo Network is connected by this."

Andrew had always felt that it was a huge waste for the Ministry of Magic not to seriously study something as promising as the Floo Network, but after reading the relevant information for the first time, he realized one thing: the Floo Network was already one of the most researched things in the entire wizarding world.

His previous idea actually had some problems. The Floo Network and Apparition were not the same thing, but Apparition and Portkey were surprisingly linked together.

How to say it, the Floo Network is a group of small magic points that can sense each other and are connected by a special spell. Each magic point uses magic while also becoming the pillar of magic.

This is simply a model of mutual complementation and achievement, and is also an important reason why almost all families can access the Floo Network.

To put it bluntly, Apparition and Portkey are a kind of magic, but the latter uses spells as a substitute for wizards to meet the higher requirements of Apparition, thereby achieving the purpose of long-distance transmission. In short, it is an eye-opener - and he already has an idea, to make another electromagnetic network based on the Floo Network, use special alchemical instruments to act as a structure similar to a fireplace, and then open up new magic to form a network of connections.

He briefly described his thoughts to Dumbledore - before he obtained this forbidden knowledge, he had not been able to explain his views in magical language, but now it was another matter.

"DreamLink?"

"Yes, Professor. We will use dream playback devices and new spells as a means of connection. We will use a large dream bead device or a device like a dream tree in the center to connect the entire wizarding world."

Andrew nodded. "For example, we can wake up in the morning and see what new models Honeydukes has released."

"It sounds surprisingly good," Professor Deng and Moody nodded, but the smile on their faces seemed more like a scary one, "What about Apparition?"

"I have no idea, professor. It's too mature, and mature spells are the most difficult to change. It's not like the Floo Network - there aren't that many wizards modifying the Floo Network. The attitude of the wizarding world seems to be to just say that as long as it works, it's fine."

"But that is the safest way, Taylor. Facts tell us that if a system that can be used by all wizards does not malfunction, it is better not to repair it."

Dumbledore nodded. "By the way, have you sought knowledge application from the Ministry of Magic in Brazil?"

"Well, I've applied, but I don't think it's going to work," Andrew shook his head. "It's basically the same thing, with the most changes being the text and language."

"I'll consider letting you come first based on your opinion. If you don't understand something, come and ask me."

"Of course I will, Professor."

"Look at Apparition more. I'm afraid you won't have time to slowly learn it as an adult. We'd better master the magic over there."

"Yes, Professor, I will."

Andrew nodded, “I’m ready for Baixian.”

"It's a very wise decision. Although the quality over there is slightly better, it's still better not to make unprepared plans. Severus taught the laboratory rules very well."

"After all, it's about your own life," Andrew shook his head slightly, "but I still don't understand something. Professor, does the Floo Network have nodes?"

"I don't know, but from the perspective of magic principles, it is definitely possible. No magic can be performed for such a long time without maintenance over such a wide distance."

Dumbledore nodded and made his guess, but when Andrew saw the headmaster blinking his eyes, he knew that Dumbledore must know the details.

"Then it should have nodes, a Floo network throughout the UK..." Andrew sighed, "A great project, and the cost is low - a little Floo powder can cover it. Magic is really the primary productive force."

"Don't try to study the Floo powder, Taylor, it's dangerous."

Dumbledore said this seriously, looking very serious.

"That is a truly taboo thing. Even if you are now, don't think about cracking it casually - especially if you have the ability to crack it."

"I'll keep that in mind, Professor."
