From Azkaban

Looking at those eyes that were the same as before, as if they could see through everything, even the future, Dumbledore did not respond. He walked slowly forward, and everything around him suddenly began to change rapidly. Soon, the whole room became what he remembered, without a single mistake.

"I didn't expect you to still remember it."

Looking at the room which was exactly the same as he remembered, the smile on Grindelwald's face slowly disappeared. He closed his eyes, and when he opened them again, all the emotions in his eyes disappeared, leaving only the relief after getting the answer.

He had never forgotten every detail of the two months in the valley, and now it seemed that Dumbledore had never forgotten it either.

"I said before, I have never regretted meeting you, and I will never forget... those past events."

Dumbledore sat on the conjured chair, just opposite Grindelwald, looking at Grindelwald, just as he always did.

It was not until this moment that Dumbledore suddenly saw Grindelwald's extremely thin body.

"You... the Austrian Ministry of Magic..."

"I left a long time ago. After all, they all firmly believed that I couldn't leave here, although that was indeed the case."

Grindelwald interrupted Dumbledore's questioning with a nonchalant tone.

"Is that so..."

Dumbledore understood what Grindelwald meant. It was impossible to trap him in Nurmengard. After all, this was the prison he had led and supervised the construction of.

It was him, Dumbledore, and the bond between the two of them that really trapped Grindelwald...

"Let's talk about it. How has the outside world become over the years without me? How have you been doing in Hogwarts..."

Without giving Dumbledore much time to remain silent, Grindelwald brought up the topic again.

In the following time, the first generation Dark Lord and White Lord chatted in this way. The topic was relaxed and the atmosphere was harmonious.

The two chatted for a long time, it was hard to tell whether it was two hours or three hours. Finally, it was Grindelwald who spoke and took the initiative to bring the topic back to the previous letter.

"I saw a lot, Albus. A lot."

Leaning lightly on the chair, Grindelwald placed his hands on the armrests, his eyes drooping and his tone heavy.

"Gellert, I'm here."

Looking at Grindelwald who was still keeping him in suspense, Dumbledore spoke with a helpless look on his face.

"Okay, okay, I'll tell you, I'll tell you......"

Grindelwald forced a smile on his face, but finally stopped procrastinating and told everything he had seen.

"The real change has arrived, Albus. It's different from what I was before. This time, it's a real trend. Locke Cazier... is the destined promoter."

Grindelwald paused at the end because he felt a little envious.

Yes, the destined promoter is completely different from who he used to be. As long as Locke Cazier keeps his original intention and moves forward firmly, he is destined to succeed.

"........................."

After listening to Grindelwald's words, Dumbledore fell into deep thought.

The answer given by Grindelwald was too absolute. Dumbledore instinctively felt that the old man was cheating, but then, Dumbledore thought of everything Locke had shown him and the magic network.

At this moment, Dumbledore had to admit in his heart that what Grindelwald said might be right. After all, let alone the future, Professor Cazier had already set off a wave of change.

Apart from anything else, Dumbledore had already speculated on the changes that the Weir might bring to the British wizarding world, and the results he obtained were all subversive.

The magical world, which has remained unchanged for many years, will inevitably undergo tremendous changes with the emergence of the Magic Network, and it is basically certain that these changes will be beneficial.

This was just the beginning. With the popularization and development of magic technology, Dumbledore could no longer imagine what the scene would be like.

"Gellert, you may be right."

Dumbledore finished his thoughts and looked at Grindelwald, a crazy idea gradually emerging from his mind.

Dumbledore had to admit that the current situation was completely beyond his control. Coupled with Grindelwald's prophecy, Dumbledore realized that he actually only had one choice.

Now that Voldemort has been dealt with by him and Professor Cazier, Gellert also bluntly stated that the next era will be the era of Professor Cazier.

"Maybe...we should also make changes..."

Thinking of the reason why he chose to write to Gellert before, Dumbledore's heart became more active.

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

As the night deepened, the lights on the top of the tower in Nurmengard did not stay on forever. As the eye-catching light disappeared, Nurmengard was no longer alive.

In the early morning, the originally quiet Hogwarts became noisy again. The energetic students walked on the way to the cafeteria. Everyone had a smile on their face, and the topics they discussed were basically everything related to the magic network.

"Harry, what new features do you think the teacher will develop?"

In the school cafeteria, Ron, who had started showing off his chicken legs early in the morning, sat next to Harry under the murderous gazes of many Slytherin little wizards.

"Didn't they say that they were developing a teaching function? Are you interested in this, Ron?"

Halle's breakfast was bread, milk and eggs, a classic combination, but the taste was average.

"It's okay. If I were to study on the magic net, I think it would be better than now even if it's boring."

Ron swallowed the chicken leg in his mouth, smacked his lips, and expressed his opinion seriously.

"Heh, being bored is not a problem of the environment, but your own problem. You still want to defeat me in this state."

Draco was eating basically the same thing as Harry, except for an extra serving of sausage. He had just swallowed the food in his mouth when he immediately started to talk back to Ron.

"You bastard! I've already told you that I was just careless last time! Don't be so arrogant, I will..."

Ron, who usually could control his emotions well, was not immune to Draco's taunts. Once he was taunted, his temper would inevitably turn red. As he spoke, he was ready to take out his wand and start fighting.

"Okay, there will be a teacher's class soon. Ron, stop making trouble and eat your chicken leg quickly. The first-year classes are taught by four colleges together, and I don't want to be late."

Ron, whose spell was interrupted by Harry, sat down angrily, reached out to pick up the chicken leg and bit it hard, as if it was Draco.

Some time later, the three of them rushed to the magical science classroom and heard the news on the way that the new professor of Defense Against the Dark Arts had arrived at Hogwarts.

"Wow, Headmaster Dumbledore is so amazing. Professor Quirrell had an accident just one day ago, and he already found a new victim... Ugh, professor."

Ron was shocked. He really couldn't understand how brave a wizard could be to take over Professor Quirrell just one day after his accident.

Volume 1: Chapter 129: Cognition

Today is Locke's first real class since arriving at Hogwarts. The previous public classes could only be regarded as popular science and demonstrations, with the majority of them containing speeches on achievements, and almost no knowledge.

However, because of the demonstration in that class and the magic network, magical science has now become undoubtedly the most popular subject in the entire Hogwarts, and every student has more or less a certain interest in it.

As first-year wizards who had just entered school, they generally had a great interest in magical science. In the large classroom specially opened for this purpose, almost all first-year students were already seated in the classroom in advance.

"Come here Harley, there's room."

The trio walked into the classroom, and Ron scanned the room, quickly finding a vacant triple seat.

As soon as he sat down, Ron discovered that the little girl sitting next to him was the little Muggle witch who had answered questions in the teacher's class before. Her name seemed to be...He something.

"Hello, my name is Hermione Granger, and I'm from Gryffindor like you."

Before Ron could recall what was going on, Hermione stretched out her right hand to him with her head slightly tilted up. Her expression wasn't overbearing, but it gave people a feeling of arrogance.

"Um... My name is Ron Weasley. You can call me Weasley or Ron."

In fact, Ron didn't want to get in touch with Hermione. The reason was very simple. His first impression or intuition told him that this was a difficult person to get along with.

"Hello, I'm Harry Potter, you can just call me Harry."

Seeing Hermione take the initiative to say hello, Harry also spoke in a friendly manner. As a girl, she had a good impression of Hermione. After all, it was she who answered Locke's questions during the previous open class.

"I know you, the savior who defeated You-Know-Who. Many students in our academy said that you should be in Gryffindor, and they thought that someone must have rigged your move to Slytherin."

Hermione seemed to have been influenced by the atmosphere and environment of Gryffindor after only joining the academy for a few days.

"Hey, watch your words! What do you mean she should go to Gryffindor? Harry is a Slytherin student, and the Sorting Hat has confirmed that. Besides, Harry is of pure family..."

Draco, who had been sitting there without saying anything, frowned and looked at Hermione. He spoke in a stiff tone, but he stopped at the end because he remembered what Locke had said. Now he could no longer advocate pure blood and discriminate against Muggle wizards.

"Anyway, go back and tell those Gryffindor guys of yours that it is the right thing for Harry to come to Slytherin. As for Gryffindor, it is not suitable for Harry."

After Draco finished speaking, he turned his head away and stopped looking at Hermione. Seeing him like this, Hermione blinked twice and then simply chose to ignore what he said.

For a while afterwards, Hermione and Harry began to chat with each other.

Perhaps because they both came from the Muggle world, the two of them got along very well and a lot of the things they talked about were questions that Ron and Draco could not understand at all about Muggle girls.

This went on until class time, and Locke stepped into the classroom precisely at the last second of class.

"good morning students"

As Locke walked up to the podium and stood still, the little wizards in the audience gradually shut up, and they quickly became quiet without Locke saying anything. Seeing this, Locke smiled and greeted the little wizards.

"Good morning, Professor Cazier~", a not very neat response sounded, and every little wizard raised his head and looked at Locke.

"Very good, it seems that everyone is very energetic, so let's start the class now."

As Locke spoke, he put the suitcase in his hand on the desk and opened the lock. The next moment, books flew out of it, gliding in the air for a short distance before landing precisely in front of each student.

"what is this?"

Looking at the book in front of them, the little wizards showed curious expressions and reached out to pick up the book. At first glance, they saw the six big words on the cover.

Magical Science. Cognition

After seeing the name, many little wizards immediately understood that this was a textbook on magical science. They became even more curious and opened the book one after another. Some little wizards even looked for the name of the author of the book.

But of course they didn't find it, because Locke did not put his name on the book when he wrote it.

"Professor Cazier, is this the textbook you wrote?"

Hermione was also one of the little wizards looking for the author. After confirming that there was no author's name on the book, she rolled her eyes, raised her hand with a stern face, and asked after Lorca signaled her to speak.

"Yes, I believe everyone knows that the subject of magic science was summarized and proposed by me. Naturally, I also need to be responsible for writing the corresponding textbooks."

While answering Hermione, Locke closed the suitcase and placed it on the side of the desk. The materials inside would not be needed in this class.

After getting this answer, Hermione put down her hand and admired Locke even more. In Hermione's opinion, anyone who can write textbooks must be a very capable person.

"Okay, everyone please stop what you are doing. Student, please let go of that poor book. It has only been out for two days."

Locke looked at the little wizard who was about to gnaw on the tip of a book, as if trying to absorb knowledge into his brain, and spoke out to stop him with a serious face.

The little wizard who was named instantly became the focus, but he reacted very quickly and was very thick-skinned. He pretended nothing had happened and put the book down.

"Very good. Then please put your books in front of you."

The young wizards withdrew their gazes and stood up, and placed the textbooks in their hands in front of them as Locke requested.

"You should have seen the name of this book."

Locke raised his hand, and magical words appeared in the air, displaying the name of the textbook in the air.

"I believe everyone is familiar with magic science, and today's protagonist is not them, but it, cognition."

Locke highlighted the Latin word for cognition, drawing the attention of all the little wizards.

“Before you start learning any knowledge, there is a crucial step, which is to establish the correct cognition.”

"As magic science is a brand new discipline, this step is of utmost importance."

"Because it is brand new, something you have never had any concept of, and..." Locke paused and said, "You may not know it, but cognition is actually one of the key points in learning magic."

Harry Potter's magic is idealistic, so the importance of cognition to magic is self-evident.

"So in the following classes, I will lead you to understand the subject of magic science. You will learn about it, understand it, and comprehend it until you can finally master it."

"This will be a long process. I hope everyone can gain something from this process. I also hope that everyone will like the path of magic science."

This is Locke's most desired vision, and it is also the reason why Locke chose to come to Hogwarts in person to teach knowledge.

Volume 1: Chapter 130: Layout

The bell rang, heralding the end of the morning classes. The little wizards filed out of the classroom, walking in groups of two or three in the corridors of Hogwarts Castle.

"Magic science doesn't seem to be difficult. Professor Kazir can understand me. It seems that I may be able to create interesting things like the magic network in the future."

"Don't brag, this is just the beginning. Have you forgotten what the professor said? This is only the first stage. There are still many more stages to come."

"I'm not bragging. I feel like I might actually have a talent for this."

Similar conversations would appear from time to time among first-year wizards, and many of them were inexplicably confident in themselves.

If it were in the normal, ordinary world, such confidence would basically be an illusion.

But this is the Harry Potter world, a world with magic and idealistic magic, so in this case, it is hard to say whether this kind of confidence will bring about changes.

Of course, some may be illusions, but for some little wizards, the results are certain, such as Hermione.

As a primary school student who had studied in the Muggle world for a long time, she had an innate understanding of the concept of technology. Coupled with her own talents, her understanding and cognitive speed of magical science was unique among all young wizards.
