From Azkaban

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

The party ended after singing the school song, and Locke met Filch holding a cat on his way to his office.

"Squibs? I remember there were quite a few of them."

Locke's eyes flickered as he observed the pitifully small amount of magic power in Filch's body compared to that of a normal wizard. After carefully memorizing the situation inside his body, he turned and disappeared around the corner.

Volume 1: Chapter 105 Open Class

Keeping the question of the Squibs in mind, Locke found the office that Dumbledore had prepared for him after asking several portraits.

"Squeak~"

When I opened the door, there was only a suitcase in the room, and the whole room was empty.

Don't get me wrong, it's not that Hogwarts is stingy, but Locke specifically told Snape to do so.

The suitcase in the room contained everything Locke brought with him, including all the books Locke had collected, a large amount of alchemical materials, and some teaching materials written by Locke.

It was natural for him to come to Hogwarts to teach without preparation. As for why he did not buy alchemy textbooks from outside, but chose to write his own, the reason was very simple. What he planned to teach was not the alchemy in the ordinary sense.

"Let's expand the room first. The current space is not enough to store things."

Locke raised his hand and was about to cast a traceless extension spell to enlarge the room when he suddenly remembered the scene he had seen before.

"Using the traceless extension spell shouldn't disrupt the castle's own magical laws, right?"

While saying this, Locke took the initiative to connect to the magic of Hogwarts to be on the safe side and began to try.

"Wow! The stability of the magic law is so strong. It seems that I thought too much."

After eliminating the problem, Locke was no longer worried. He raised his hand to expand the room, then opened the suitcase through the air and took out all the things inside, placing them one by one as the room rapidly deformed.

After five or six seconds, the originally empty room completely disappeared, and a new room appeared, with the back half filled with bookshelves and storage racks and the front half serving as a living area.

"Um"

Looking at his masterpiece, Locke nodded with satisfaction, raised his hand, took a book from the bookshelf, sat on the chair and began to read.

Locke did not plan to sleep tonight, just like last night, because in the past two days, as one member after another left the UK, new magic network secondary cores would be connected to the main core from time to time.

Locke could naturally shield the connection between the secondary core and the main core, but he didn't intend to do that, so he simply didn't sleep.

Anyway, for Locke now, not sleeping for a few days will not be a problem at all. Spending two hours of meditation every morning is completely enough.

For Locke, the night always passed quickly. In the blink of an eye, a new day came.

Early in the morning, Locke first found Professor McGonagall to confirm his course schedule and the class time of the first open class with her.

"Let's schedule the open class on Thursday. Three days is enough for class preparation and notification."

The open class is a class for students to get to know Locke. Its importance is self-evident. Students will use this class to determine whether they are interested in it and whether they want to take Locke's course.

Even Locke had to take this aspect seriously. After all, he was a new professor and there was basically no alchemy course before Hogwarts.

If the open class is not well organized, it will be very embarrassing if no students choose his class after it starts.

However, Locke's worries were completely unnecessary, because just when he was confirming the courses with Professor McGonagall, Snape had already informed the Slytherin of Locke's news after the banquet last night.

Now almost all the young Slytherin wizards in the Round Table know that Locke is that adult. Naturally, they also know very well what they should do.

Starting from this semester, even if they are not taking major courses, they have to devote enough energy and time to concentrate on alchemy regardless of weather conditions.

It's not just because Lor is the leader of the Round Table, but also because this is an opportunity to receive Locke's teachings and to show himself in front of him.

On the very night that Snape announced the news, many owls flew away from Hogwarts, spreading the news that Locke suddenly appeared in Hogwarts and served as professor of alchemy.

The pure-blood families who received the news were very surprised, but they would not miss such a good thing. They wrote letters to tell their children to seize the opportunity, study hard, and strive to show their faces in front of Locke. If they could make Locke remember them, the family would surely soar in the future.

No one contacted Lucius to inquire. They knew very well that since Lucius did not inform them, it meant that there was no need for them to know about this matter.

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

After deciding on the course schedule and open class times with the professor, Locke went to the Hogwarts library as soon as possible.

"Professor Cazier"

There were no students in the library in the early morning and Locke was the only visitor. Seeing him, the librarian, Mrs. Pince, took the initiative to greet her.

"Good morning, Madam Pince."

After briefly greeting the stern librarian, Locke went to the banned books area with a clear purpose, looked at the banned books that looked like treasures, and began to select.

Locke spent most of the first day in the library. After the library closed, he returned to his office to prepare for the open class.

On the second day and the day after, Locke repeated the process. During this period, Lucius reported through the Magic Network that the "Magic Network" company located in Diagon Alley had completed its opening and had begun to promote the Magic Network according to Locke's arrangements.

Just like that, Thursday came in the blink of an eye. As the morning classes ended, the little wizards who had already received the news rushed to the open class classroom in twos and threes.

Open classes are optional, but it is obvious that many young wizards are very interested in this new thing called alchemy, so they are willing to join in the fun.

"Ron, hurry up, we can't be late."

In the corridor of Hogwarts, Draco, a Slytherin, and Ron, a Gryffindor, were rushing to the open class classroom.

"Slow down Draco, there's still plenty of time, we won't be late."

Ron quickened his pace and reached out to pull Draco, who was about to run in front of him.

"Why are you in such a hurry? Forgot what the teacher said, you should control your emotions."

As soon as Ron finished speaking, Draco stopped, turned his head, narrowed his eyes and looked Ron up and down with a scrutinizing look.

"You really don't have any credibility when you say this, and you try to control your emotions."

Draco shook his head and turned to continue on his way, but this time his pace slowed down.

"Oh, you're not much better."

Ron didn't get angry with Draco. He simply retorted and walked forward to walk side by side with Draco.

When Ron and Draco walked into the open class classroom, there were already many students inside. At the back of the classroom, there were also a few professors sitting, who seemed to have come to join in the fun.

"Tsk, Professor Snape is here too. I was wondering why Harry disappeared after class."

Looking at Snape who was talking to other professors, Draco lowered his eyes and saw Harry in front of Snape.

Volume 1: Chapter 106 Open Class (II)

Following Draco's line of sight, Ron also spotted Snape and Harry sitting in front of him, and immediately looked helpless.

"It's normal. Professor Snape has been like this for a long time."

Just as Ron was speaking, two arms suddenly stretched out from behind him and handcuffed him on the left and right.

"Little Ron, did you miss us?"

"We didn't miss you at all."

The Weasley twins were grinning. When they saw it was them, Ron didn't struggle. He just rolled his eyes and turned his head away.

"That's perfect. I don't miss you guys at all. Come on, we've only been apart for one night. What do you think you are? A chicken leg?"

Seeing that the people coming were the Weasley twins, Draco immediately looked disgusted. He moved his buttocks and gradually distanced himself from them while the three brothers were talking.

Time passed like this for more than ten minutes, during which time students continued to arrive. Professor McGonagall and Professor Sprout, who had no classes, also arrived.

"Minerva, do you know anything about Professor Cazier? What is his level?"

Professor Sprout and Professor McGonagall sat together. The two, both head of the house, had a very good relationship.

"I don't know. He was interviewed by Dumbledore. I didn't even receive any news before the dinner. But he came with Severus to the dinner. Perhaps you can ask Severus."

Professor McGonagall said, turning to Snape, but Professor Sprout shook his head decisively at the suggestion.

"Forget it, just wait a little longer, we'll know soon."

Soon, as the class time arrived, Locke walked into the classroom on time, wearing a silver-gray suit, with a gentle smile on his face. His well-proportioned tall figure and handsome face made many little witches' eyes shine.

To be honest, except for Slytherin, most of the young wizards present came because of interest, but the boys were interested in alchemy, while the girls were different.

Under the gaze of everyone, Locke walked through the students, stepped onto the podium, and looked around.

Locke's sight seemed to have magic. Wherever his sight passed, everything became quiet quickly.

As Locke's eyes walked across the entire classroom, the entire classroom became completely quiet.

Then, under everyone's gaze, Locke nodded slightly, and then a gentle voice was accurately transmitted to everyone's ears.

“We are starting class now.”

At this moment, the professors sitting at the back were looking at Locke's empty hands, and all of them, except Snape, showed surprised expressions.

The sound Locke made just now clearly had a magical effect, but Locke did not have a wand in his hand. The professors knew very well what this meant.

"First, let me introduce myself. My name is Locke Cazier. You can call me Professor Cazier. I will be your alchemy professor from now on."

As the professors were surprised, Locke's voice continued to sound, and as he spoke, the corresponding name appeared in the air.

Seeing this, Professor McGonagall widened her eyes slightly, not because she was more surprised, but because she vaguely guessed something from Locke's posture.

"Is he planning to spend the entire class like this?"

Professor Sprout on the side said what was in her mind. Looking at Locke who obviously had no intention of taking out his wand, Professor McGonagall pursed her lips and did not respond.

"Before we begin, I would like to ask you a question. Do you know alchemy?"

On the podium, Locke looked at the young wizards below and asked a small question.

Locke originally thought that not many people would answer this question, but unexpectedly, as soon as he finished speaking, a group of little wizards raised their hands.

Locke was a little surprised and quickly glanced at the crowd. In the end, he did not choose Harley, Draco and the other four who had raised their hands. Instead, he randomly picked a young wizard from Slytherin.

"This classmate"

The Slytherin student who was called was very excited. He took a deep breath and stood up. He first bowed to Locke, and then began to answer after he stood up.

“Alchemy is an ancient technique that seeks eternal life and endless gold. It is also a path to explore the origin of all things and pursue the ultimate mystery.”

It's a very formulaic answer, but it's also normal. Hogwarts didn't attach much importance to alchemy, and there wasn't even an alchemy course before Locke.

The reason why this answer can be given now is that the student researched it overnight last night.

"Well, not bad, five points for Slytherin."

Raising his hand to motion the little wizard to sit down, Locke was not satisfied with his answer, but he was also quite surprised. After all, what he said was indeed the key point of alchemy.

"What the student just said is very correct. That is indeed the origin of alchemy in a broad sense, the pursuit of endless gold. This is also the origin of the name of alchemy."

After hearing Locke's words, many young wizards in the audience showed money-grubbing expressions, and their interest in alchemy began to soar.

"However," Locke changed the subject before the little wizards could imagine much, "Although the original pursuit of alchemy was endless gold and eternal life, so far, endless gold has not been achieved, and eternal life can only be questioned."

Hearing this, the little wizards in the audience all showed disappointed expressions. Seeing this, Locke smiled slightly. These little guys really had a nice idea.

"So compared to alchemy, the focus of alchemy in the process of inheritance is actually constantly leaning towards another direction, which is what the classmate just said, exploring the roots of all things and pursuing more extreme mysteries, that is, those magics that have not yet been discovered."

At this moment, the young wizards in the audience all looked confused. It was obvious that they basically could not understand what Locke said. Locke was not surprised. Theories were boring and difficult to understand.

So Locke flipped his hand, and an alchemical item prepared in advance appeared in his palm.

"It's hard for everyone to understand just by saying it. Let me explain it in a simpler way. The mainstream of alchemy today is no longer the pursuit of creating something out of nothing, but the exploration of existing things. From this, products such as magic items have been derived."

“Like this one in my hand”

After hearing Locke's words, all the students focused their attention on the square block in Locke's hand.

"Om~~"

Dense magic patterns appeared on the cube, and the next moment, the entire cube suddenly exploded, then gathered and expanded into a huge pool of silver-white liquid, floating in front of Locke.

Before the little wizards could wonder, the silvery-white liquid began to change its shape in front of their surprised eyes, into a lion, an eagle, a python, a honey badger, a griffin, and a dragon. Every time it turned into an animal, that animal would roar.

The eyes of the students below the stage gradually began to change. At this time, Locke walked aside and ignored the imitation "Moon Marrow Spirit Liquid" that was still changing.

"Professor Kazir, if we choose your class, will you teach us that?"

A young Gryffindor wizard raised his hand and asked with shining eyes.

"Of course, but don't worry, this is not the main point I want to talk about today. This is just an introduction so that you can understand what I am going to say next."

"Because what I am going to say next is what I really intend to give you."

Having said that, Locke looked at the little wizards below. In fact, he did not expect them to understand now. He stood here for another purpose. It did not matter whether these little wizards could understand it or not. After all, this was just the beginning.

Looking at the pairs of curious eyes in the audience, Locke did not keep the suspense. He raised his hand slightly, and a string of words outlined by magic appeared in front of him.

"This is what I plan to teach you from now on, a new path born out of alchemy that will lead us into the future."
