A magical journey that begins in Azkaban

Daphne's spiritual power is a deep sapphire blue. With the mysterious help of the jade slab, her magic power grows rapidly and vigorously.

The fatigue of the body seems to disappear under the surge of spiritual power. She can feel every ray of magic power in her body, surging like a spring in spring.

"What on earth is this?" Daphne looked up, her eyes attracted by the jade slab emitting a faint light next to her.

Rogge leaned over and whispered in her ear, "This should be a treasure excavated by the goblins from the depths of the pyramid, but the content on it is still like an unsolved mystery and needs further translation."

Although his rune attainments are outstanding among wizards, he has no idea where to start with the ancient and obscure short sentences on the jade slab.

If this is a secret about potions, Rogge will study it in depth at all costs. But the jade slab in his hand is more like a magic tool like a black box.

He doesn't care about the structure and principle of it, but only cares about its function and how to use it.

Daphne chatted with him for a while, and finally had to go back to rest. Roger watched her leave, and the closed door seemed to take away the warmth in the room, and he yawned unconsciously.

Breakfast time in the hall became a battlefield for students to debate passionately. They waved the Daily Prophet and fiercely discussed whether they should use magic to block the Atlantic Ocean to prevent any wizards and Muggles from illegally crossing the border.

However, not everyone agrees with this kind of isolationism. For example, Mr. Harry Potter is the most prominent opponent. He firmly believes that Voldemort must be defeated and this cancer of peace must be eradicated completely.

"Rog, help us quickly." Malfoy found himself at a disadvantage in the debate and hurriedly asked Roger for help, "Harry said that the Ministry of Magic is appeasing. This word sounds negative, but what does it mean?"

"Well, it's probably similar to raising a tiger to harm you." Roger explained softly, cheering Draco up and letting him take on the responsibilities of a prefect.

He turned the newspaper to the other side, and the entire page was almost occupied by an advertisement for "Madam Malkin's Robe Shop". Madam Malkin is promoting her latest robes for protection from spells, and they are endorsed by the Ministry of Magic.

Roger usually has no interest in this kind of debate. In his opinion, any argument will eventually become an illusory steam. Attacking each other's words and deeds and providing emotional value to the audience is the winning formula for debate.

However, Harry and Draco's views do reflect the current polarization of the British wizarding world.

The wizards led by Dumbledore strongly demanded to join the American battlefield, while the Ministry of Magic led by Minister Amelia firmly opposed it.

In fact, the latter has won the support of most wizards. Any attempt to leave the British wizarding world without permission may be arrested and tried.

"It's better to be chaotic." Roger's mouth curled up slightly, and finally found the news of the increase in the price of crucible bread in the corner of the newspaper.

Although it only increased by 3 copper knuts, combined with the information provided by the goblin, he speculated that the price of food in the Muggle world may have gone crazy.

Owl Seller brought a letter from asset manager Thompson, who wanted to make some large investments in the futures market. Roger thought for a while, then replied to agree to his request.

He thought to himself that if several volcanic eruptions occurred and the volcanic ash reflected the sunlight in the sky, the greenhouse effect would be quickly alleviated. Such a future would be a beautiful and fruitful era.

The debate soon turned into a quarrel, and the students of Slytherin and Gryffindor began to attack each other. The bread and mushroom soup on the long table quickly turned into shells, guided by the wands and smashed at each other.

The situation slowly got out of control, and Ravenclaw and Hufflepuff were also involved in the breakfast war.

Professor McGonagall stood quietly at the door of the hall, her sharp eyes swept over every student who was making trouble in the hall. Not only ordinary students, but even the prefects and the president of the student union joined the melee.

Suddenly, someone stopped first, and then the noise in the hall disappeared instantly. A piece of bread still gliding in the air accurately hit the head of a student of Hufflepuff College, and he couldn't help but let out a cry of surprise.

"Aha, so fun!" Peeves' voice stood out in the crowd. He held the tray in one hand and threw the bread at every long table with the other hand.

"Peeves?" Professor McGonagall's stern voice froze Peeves instantly. He hurriedly dropped the tray and disappeared into the wall.

"Gryffindor deducted 50 points, Slytherin deducted 50 points, Ravenclaw deducted 50 points, and Hufflepuff deducted 50 points." Professor McGonagall's eyes swept coldly over every student in the hall. Her voice was firm and powerful, "All participating students are responsible for cleaning the hall."

Deducting points and cleaning were not the most frightening things for the students. What really made them nervous was that there was Professor McGonagall's Transfiguration class in the morning. In order to avoid getting into trouble in class, the students acted quickly. Roger also joined the ranks of Slytherin students to help them clean up the hall.

With the help of magic, the chaotic hall soon returned to its original appearance. Unfortunately, the wasted food can only be thrown away. Perhaps the house elves will take it to the Forbidden Forest to feed the wild animals.

The morning class seemed a bit dull. Professor Flitwick first spent fifteen minutes emphasizing the importance of the OWLs exam, and then spent an hour reviewing the Flying Spell.

Finally, he assigned a lot of homework for the first time. The dean, who never stayed late, seemed to have changed.

The situation in the following Transfiguration class seemed even worse. Professor McGonagall's expression was as serious as a stone sculpture, and her voice was loud and firm: "If you don't study, practice and apply seriously, then you can't pass the exam..."

After a long warning and encouragement, she finally started today's teaching content: the Vanishing Spell.

"The Vanishing Spell is simpler than the Summoning Spell you practiced, but it is still the most difficult magic that will appear in OWLs, no doubt about it!" Professor McGonagall drew out her wand, and with her spell, the huge podium disappeared instantly in full view of everyone.

She then introduced: "This spell can make living and inanimate objects disappear."

"What!" A cry of surprise suddenly rang out in the classroom, and the students looked at Professor McGonagall with fearful eyes.

If the professor can make a desk disappear instantly, can she do the same thing to wizards? After all, the professor has made it clear that the Vanishing Spell is also effective for living objects.

"Does anyone know the limits of the Vanishing Charm?" Professor McGonagall asked. This time even Hermione was silent, not knowing the specific answer.

Seeing that the classroom was about to fall into silence, Roger slowly raised his hand. Professor McGonagall nodded and motioned him to answer.

"In terms of magical mechanism, the Vanishing Charm is a pure Transfiguration, because it changes the composition structure of the object and turns it into nothingness." Roger replied.

"Rog, please explain it in detail." Professor McGonagall encouraged him to continue.

"For example, the lecture table just now, it is composed of tiny substances. And the substance itself cannot construct wood. There is a layer of structure between the substance and the object, which determines the shape of the object."

Most students still did not understand Roger's words, only Professor McGonagall understood that this had touched the essence of Transfiguration. She did not interrupt him, but listened quietly and gave him full respect.

"But isn't the lecture table made by a carpenter?" Harry asked in confusion.

Roger shook his head and explained softly: "This is the most easily misunderstood part. The carpenter did make the lectern with wood, but the wood itself has never changed. Just like a house made of mud, no matter how beautiful it is, it is still mud in essence."

"The real function of Transfiguration is to use magic to build a new structure so that the material that makes up the wood presents other forms."

"The stronger the magic, the deeper the degree of change in the structure, and the longer the duration of Transfiguration."

"So, the Vanishing Spell directly destroys the structural layer in the middle. It makes the form disappear in appearance and return to the material state that is invisible to the naked eye. In other words, decomposition."

The classroom fell silent. Although Roger explained it very clearly, these concepts were still difficult for others to understand. Every word he said was recognized, but when they were put together, they had no idea what it meant.

"To put it simply, if you want to use the Vanishing Spell to achieve the effect of murder, you need to use magic to decompose all the structures of the human body in an instant."

"Inanimate objects are similar to fixed structures, and living objects are changing every minute and every second." Roger smiled and explained the limitations of the Vanishing Spell, "The more complex the life is, the more difficult it is to decompose."

"This difficulty is far higher than the Unforgivable Curse. And the remaining powerful magic is enough for the Aurors to know the identity of the murderer." He shrugged and said softly: "In comparison, other spells are more effective."

Professor McGonagall smiled and nodded, giving a concise summary: "The Vanishing Spell, turning into nothingness, can also turn into everything."

Her words directly pointed out the essence of Transfiguration, and made the profundity and power of the Vanishing Spell more deeply rooted in people's hearts.

"The Vanishing Spell is the watershed and cornerstone of Transfiguration. On it, you can use the same substance to transform different materials." Professor McGonagall continued to explain.

"Professor, what if you want to make the material different?" Hermione asked curiously, "For example, turn soil into food or something like that."

"Good question." Professor McGonagall smiled and continued, "If you want to achieve the transformation of matter, you have to use alchemy. But so far, only the legendary alchemists can achieve such a transformation."

"Rogge, you have a very deep understanding of Transfiguration. Slytherin will get 20 points for your excellent answer!" Professor McGonagall announced. This is also the largest amount of extra points she has given to the school since she started teaching.

The hourglass of Slytherin in the entrance hall rose rapidly, surpassing the other three schools. As long as he is willing to answer the professor's questions, the school cup can only stay in the Serpentine School.

Many students hope that Professor McGonagall can talk more about alchemy. After all, converting ordinary metals into gold is the dream of most wizards.

Roger is skeptical about the transformation effect of alchemy. In his opinion, if you want to use alchemy to convert 1 gram of gold, regardless of the formula and astronomical conditions, the energy required is unimaginable.

Even if Merlin, Dumbledore, Grindelwald, Nicolas Flamel, and even Voldemort and myself who are cheating are added, the energy demand cannot be met. Unless the power system of the whole world undergoes a qualitative change.

With this energy, it is better to find a gold mine and work as a miner to pan for gold. Even if it is to build a spaceship to catch meteorites in outer space, it is better than wasting time in front of the alchemy table.

Professor McGonagall did not introduce alchemy too much, after all, it is not the strong point of Hogwarts. Moreover, only wizards who meet certain conditions can take this course in the sixth and seventh grades.

She restored the disassembled desk to its original state, and then distributed the prepared snails to everyone. Compared with Roger's explanation that made people sound a little dizzy, the difficulty of learning the Vanishing Charm was even more amazing.

Most students did not succeed in making the practice snail disappear until the end of two classes. However, Roger, Daphne and Hermione all succeeded. It is worth mentioning that Daphne's speed was even faster than Hermione.

They each won 10 points from Professor McGonagall. In a Transfiguration class, Slytherin directly earned 40 points, making up for the points deducted in the morning.

Hermione was a little anxious to guide other Gryffindor students, but no one learned it until the bell rang. However, they won a new reward from Professor McGonagall, a homework on the Vanishing Charm.

At this moment, the fifth-year students finally understood how much homework they had to do. The snake-man paper in the Potions class, the wand handle in the Defense Against the Dark Arts class, the practice of the Spell in the Charms class, the Vanishing Charm in the Transfiguration class...

In addition to the required courses, they also had elective courses to take. If those professors kept the same pace, they would even have to cancel their plans to go to Hogsmeade on the weekend.

Now, they experienced the pressure of studying firsthand, and they wished they could get sick immediately to escape the clutches of homework and exams.

But when they thought about the next class, students had to run to the library to find information and do homework at the same time.

Ron stood outside the library, with an embarrassed blush on his face. The notice board that prohibited him from entering the library was like a huge label, tightly attached to the stone wall beside the door.

Although whether he entered the library or not had little impact on his grades. But as a prefect, should he still be turned away?

Passing classmates whispered, their eyes wandering between Ron and the notice board. Those faint contemptuous laughs, like tiny silver needles, pierced his heart one by one.

Ron's mood instantly fell to the bottom, and the shining prefect badge on his chest became particularly heavy, making him feel unprecedented shame. After watching Harry walk into the library, he made up his mind and ran quickly towards Professor McGonagall's office.

"Dean, I..." He looked at the square glasses on Professor McGonagall's face, took a deep breath, and said bravely: "I want to go to the library to study."

Professor McGonagall was stunned for a moment, then replied gently: "Mr. Weasley, I am very happy that you can realize the importance of learning."

"Several of your brothers have served as Gryffindor prefects in the past ten years. When I sent you that letter in the summer vacation, I hoped that you could become more outstanding because of this badge."

Ron was a little embarrassed by these words. He lowered his head and smiled brightly. He waited patiently, expecting Professor McGonagall to lift the library ban.

But the office fell into silence, with only the rustling sound of the feather pen on the parchment. He looked up and found that Professor McGonagall had immersed herself in her work again.

"Ahem..." Ron coughed unnaturally, trying to attract Professor McGonagall's attention.

"Anything else?" McGonagall took off her glasses and looked at him puzzledly.

"That... I was... banned from entering by Madam Pince a few years ago." Ron stuttered, his eyes quickly swept across the headmaster's face, and noticed that the gentleness in Professor McGonagall's eyes was quickly retreating.

"Professor, that happened several years ago. Because of the noise in the library, I have realized my mistake..." He tried to explain.

"You should go to Madam Pince to apologize." Professor McGonagall reminded, "Although I am the deputy headmaster of Hogwarts, I have no right to interfere with Madam Pince's library."

"Or, you can go to Principal Dumbledore." She added.

"I... I know." Ron hurriedly fled the office. He looked down at the badge on his chest and muttered secretly, "I am a prefect, and I must ask Madam Pince to lift the ban!"

He never felt that he had done anything wrong from beginning to end, but for the integrity of his privileges. It was also to prevent other students from gossiping and slandering him behind his back.

Professor McGonagall looked at the wooden door and shook her head helplessly. Madam Pince cherishes books very much and looks quite serious.

But she is very kind at heart and is definitely not a vengeful person. If Ron had apologized earlier, the ban on the library entrance would have been lifted.

Perhaps, it was because Ron never took the library seriously. Like his twin brother, he valued playing more than studying. Otherwise, he would have come to me or Madam Pince long ago, instead of waiting until now.

"Maybe the prefect badge can really make him realize his responsibilities." McGonagall said to herself, and then went on to deal with other things in the school.
