Ryan was in a hurry to go back and summarize the information, because the most important thing for him today was to serve as a link between Ryan's knowledge of plants and magic. Let the botanical knowledge that Ryan has mastered turn into his own strength.

And this kind of important magical knowledge is simply not found on weekdays, even if the professor is optimistic about a certain student, the notes given are only a partial extension of the classroom knowledge. If it weren't for the confirmation that they were going to pass on their mantle, this core knowledge would never have been revealed from their mouths.

So he was a little stunned when Ryan was stopped by the professor, because he could see that the professor was also in a hurry to bring the information he had obtained from Ryan into his own research. Since both of them were in a hurry to go about their own business, why would the professor let him stay a little longer.

Soon the answer was revealed, and Principal Fernando walked in through the door with a serious face. After seeing Ryan and the two of them, he said directly: "Old Bark, I came over after receiving your notice, can you start now?"

Lane knew that South Americans had a habit of calling each other by nicknames, and that the nicknames associated with plants meant that the professor was an authority in this regard. But what does the principal mean by starting now?

Headmaster Fernando turned to Ryan at this time and said, "You may not know, but you have just completed a formal academic exchange between wizards. In this case, as long as one party asks that the knowledge will not be passed on, then magic will be used to ensure this matter. Of course, in this case, the other party will also have to pay the same price. ”

Sure enough, the blockade of knowledge in the wizarding world is very strict, and it is estimated that the average hemp wizard does not have enough knowledge to fight against those pure-blooded wizard families. That's why, even today, the power of the wizarding world is still firmly in the hands of pure-blood wizards.

It's no wonder that the wizarding world isn't moving fast, and everyone is so keen to find the wisdom left behind by the ancient wizards. Because this method of inheritance is too easy to cause many things that have been researched before to be lost, people will have to start studying again if they want to develop in this direction. This kind of repetitive research is not only a waste of resources, but also a significant slowdown in the overall progress of the wizarding world.

Although Ryan has countless grooves to spit on this conservative knowledge transmission environment in the wizarding world, now this is on other people's territory, and he can only obey other people's arrangements.

Soon, under the guidance of the principal, Ryan and the professor held hands together, and the principal pointed to the place where the two shook hands with his wand.

Two hours later, Ryan walked out of the office, rubbing his arm and thinking about the tongue of fire that had just wrapped around his hand. Through the unbreakable oath just now, Ryan and the professor swore to each other not to reveal any knowledge they had received from each other. At the same time, the headmaster uses a magic item to rule that Ryan's knowledge is more valuable, so the professor must pay a corresponding price to make up the difference.

Ryan naturally chose knowledge as the content of compensation, after all, after knowing the preciousness of knowledge, he must choose the most precious thing. The professor thought about it and took out a thin notebook as compensation, but asked Ryan to only look at it here and not take it with him.

After confirming through the principal that the weight of this notebook can make up for the previous gap. Ryan spent more than two hours in his office looking through the notebook that the professor had given him, and did not leave until he was sure that he had mastered the knowledge of the notebook.

The knowledge in the book is the basic content of what the professor talked about in the speech just now, and with this thing, Ryan can immediately start researching how to use the knowledge of plants to improve his ability after he goes back. There is no need to spend time working backwards from the knowledge gained from the discussions, as previously planned.

But the most important thing now is to go back to eat, after all, after tossing in the morning, people are already hungry. Ryan thought about making a beeline down the hall.

In the hall, he met Hermione, who had just come to eat after a transfiguration class, and when she saw Ryan, she asked, "What did you do upstairs with the professor? Why didn't you come to the Transfiguration class later?"

Ryan looked at the bustling crowd around him and said, "I've been hungry all morning, let me finish my meal." Hermione also noticed that there were too many people around to talk, so she buried her head and ate quietly.

After three mouthfuls and two mouthfuls of hurried lunch, on the way back to the carriage to pick up the afternoon textbook, Ryan picked up the morning's events and told Hermione, mainly highlighting the secret of knowledge in the wizarding world, and showing her the traces of the unbreakable oath on her arm as evidence.

Hermione's face was a little ugly after listening to Ryan's story, "Does this mean that both Muggle and Mop wizards are far from pure-blood wizards?" After all, based on what you've seen, pure-blood wizards probably have a myriad of knowledge that we can't even access, and no matter how hard they try, there is nothing they can do to change the status quo of the wizarding world. ”

"You don't have to worry so much. Ryan wanted to prevaricate, but looking at Hermione's serious eyes, he suddenly remembered that she had set up a lifelong ambition in the fourth year. This meant that Hermione was far more mature than ordinary people in some aspects, and thinking of this, Ryan decided to discuss this matter with her seriously.

"Well, you're right to be worried. Ryan began to reveal a series of cruel truths to Hermione: "I got some information from Percy, which shows that although the Ministry of Magic has a large number of hemp wizards, they are generally grassroots staff of various departments, such as memory cancelers, Aurors, etc. And the managers of various departments are basically pure-blood. In the important Wizengamot and the Department of Mysteries, most of the members come from various magical families, and the only hemp wizards appear as members of a pure-blood family after marrying purebloods. ”

Speaking of this, Ryan suddenly remembered that Hermione could become the Minister of Magic in the original books, and it was likely that after she married Ron, the Weasley family, the most important pure-blood family in the post-war period, stood behind her.

"Economically, too, the shops on Diagon Alley are basically the ancestral property of pure-blood wizards who have been passed down from generation to generation, and hemp seeds are used as part-time workers in them at most. ”

Ignoring Hermione's increasingly ugly face, Ryan continued, "As far as the dark arts we hate the most, hemp wizards make up a large percentage of the people who are caught in Azkaban every year because of dark magic. For example, most of the half-hung dark wizards in Tumbledown Alley are hemp seeds. ”

"How is that possible?" Hermione let out a surprised voice. Because she had the impression that the dark arts had been equated with Slytherin House, and that Slytherin students were pure-bloods and half-bloods. So she always thought that only purebloods liked the dark arts. At this time, it was natural to hear Ryan say this, and it was incredible.

The two of them had already returned to their carriage by this time, and after taking a seat at the table in Ryan's dormitory, Ryan poured himself and Hermione a glass of water and said, "It's true, you can understand it after listening to my analysis." ”
