I've already become a Hogwarts professor, and the system only just appeared.

Last week at the end of class, Su Yu had everyone copy a book called "The Complete Book of Human Weapons," and naturally, this class would be about weapons.

"I believe everyone has a certain understanding of Muggle weapons. So, who would like to talk to me about what you think is the most amazing Muggle weapon?" Su Yu posed a question as soon as class started.

Fred was the first to raise his hand and said, "Professor Su, I think the most amazing Muggle weapon is the atomic bomb. Even Dumbledore couldn't possibly destroy a city with a single spell. It's truly incredible!"

He gestured for Fred to sit down, and then called on several students, including Cedric and George, who had raised their hands. They each had their own opinions, but their overall focus was on high-powered weapons.

Finally, Su Yu pointed to Trish, who had raised her hand, and the girl said, "I think the most amazing weapon of Muggles is firearms, especially revolvers."

"The power of this weapon, in the event of a surprise attack, is such that if it hits a wizard in the head, it can absolutely kill any wizard."

"Moreover, this weapon is relatively simple to make. After learning a little about it myself, I can replicate it using Transfiguration. This means that it is a weapon that can be made available to all Muggles."

"If, I mean if one day, Muggles really go to war with wizards, I think the wizards who die from guns will be the most numerous."

Su Yu snapped his fingers as usual and said, "Very good, Ravenclaw gets 5 points."

Since unlocking achievements related to adding and deducting points, Su Yu has been generous in this regard, seizing every opportunity to add or deduct as many points as possible.

Su Yu gestured for Trish to sit down and said, "Tris is absolutely right. Firearms, as the most basic weapons for Muggles, have the advantages of portability, versatility, and ease of operation."

"For adult wizards, when Muggle weapons of mass destruction come at them, they have enough time to use Apparition to escape."

"But if you're shopping or enjoying a meal, and a Muggle suddenly shoots you from behind, how many of you are confident you can survive?"

"Therefore, I agree with Trish that, for wizards, firearms are the most amazing weapons that Muggles can create."

It was clear that some students below were unconvinced, but Su Yu did not give them a chance to refute him. Today, he mainly wanted to show these kids his alchemy skills.

He then continued, "We wizards naturally want to learn things that are good, so can we wizards master firearms?"

The students below were silent for a moment, then Cedric raised his hand and said, "Professor Su, the power of firearms is indeed impressive, but they also have significant limitations."

"I think there's only one chance to use this against a wizard, and it has to hit the head, otherwise the wizard can quickly heal himself from this kind of physical damage."

"And once the wizard recovers his health, there are a hundred ways to subdue that gun-wielding Muggle."

Su Yu chuckled and countered, "What if the one wielding the gun is a wizard? I'll come up and shoot you first, ideally hitting you in the head. Even if I miss, you'll still have to fight me with magic while you're injured. Once you go for treatment, I can gain the upper hand, right?"

Cedric's expression froze. He hadn't really thought of it that way before, and felt that doing so was too despicable and would be a disgrace to wizards.

Su Yu pressed on, saying, "Or let's go a step further. What would it be like if we could make Muggle pistols fire magic bullets?"

Fred and George exchanged a glance, both seeing a strange glint in each other's eyes. Fred stood up and said:

“I understand, Professor Su. If we use magical bullets to replace Muggle bullets, then pistols can be fully integrated into the wizarding combat system and could potentially become the deciding factor in a battle.”

Su Yu glared at Fred and said, "Fred, you didn't raise your hand. Who told you to stand up and speak? Five points deducted from Gryffindor, but because of your excellent thinking, I've decided to add another five points to Gryffindor."

"Huh?" Fred was completely dumbfounded. What was Professor Su trying to do? Deducting five points and then adding five points, what was the point of this?

What he didn't know was that this was of great significance to Su Yu, as it would not only not change Gryffindor's current score, but also allow him to take another step forward in his second-stage achievement as "Gryffindor's Enemy," making it perfect.

Chapter 22 Gemma Farley

Su Yu took out a Colt Python from his Seamless Extension Bag and said with a smile, "Actually, I've already done some preliminary magical modifications to the pistol. Anyone want to try its power?"

"Me!" George and Fred raised their hands almost simultaneously, eager to try.

"Excellent! You two come up on stage and stand over there!" As he spoke, Su Yu waved his magic wand, and the space on the stage suddenly expanded, forming a long and narrow fighting arena.

This was a combined magical effect produced by the Seamless Stretch Charm and the Transformation Charm. It might seem rudimentary to Professor McGonagall, but it made the children gasp in amazement.

Through a full day of learning, Su Yu gained some new insights and ideas about the Transformation Charm, and now it was a good time to try it out, with obviously good results.

Su Yu stood at one end of the fighting ring, while George and Fred stood at the other end. Su Yu looked down at the crowd and asked, "Is anyone else here?"

Cedric, sitting below, couldn't help but speak up: "Professor Su, are you trying to take on all of us at once? Forgive my bluntness, but that's not going to be easy!"

“Hufflepuff loses 5 points for questioning the professor, but considering your kindness and sincerity, Hufflepuff adds another 5 points! You’re right, I’m going to accept both of your challenges at the same time.” Su Yu took the opportunity to deduct another 5 points from Hufflepuff.

Having received an affirmative answer, Cedric ignored the previous point deductions and additions. Feeling slighted, he said indignantly, "Professor Su, although we are only third-year students, we are not without fighting power. Don't underestimate us."

Su Yu didn't explain, but waved his hand and said, "Whether you underestimate me or not, come up and try it and you'll know!"

Cedric stepped onto the dueling platform, and Su Yu then called up Trish from Ravenclaw. At this moment, a Slytherin boy named Frye pursed his lips and muttered under his breath:

"One against four? How arrogant! Does he think he's the Dark Lord? Let's wait and see!"

Su Yu immediately grabbed the kid and said, "Slytherin, deduct five points. Since you think I'm arrogant, why don't you come up and try it with me?"

When Fry was called out, his face flushed slightly. He looked at Su Yu, seemingly waiting for Su Yu to give him the academy affiliation and then add it back.

Su Yu said, "If you can hit me with a spell, I can add 10 points to Slytherin's score!"

“Alright, it’s a deal!” The young Slytherin wizards still valued honor, or rather, face. Frye was no exception. Hearing Su Yu’s words, he gritted his teeth and stepped onto the dueling platform.

Seeing that the five junior wizards opposite him were already in position, Su Yu raised the revolver in his hand and said, "Alright, let's begin this duel. I will count to three and then use it to unleash your weapon. You can do whatever you want."

"One! Two! Three!" When Su Yu counted to three, the five little wizards opposite him simultaneously raised their wands and began chanting spells.

Su Yu, on the other hand, resembled a Western cowboy, aiming a revolver at the five people opposite him with his right hand, while controlling the recoil with his left, bang bang bang bang bang...

The magic pistol naturally didn't make a gunshot; the sound was just a special effect added by Su Yu himself. Five red beams shot out from the revolver one after another, flying towards the five little wizards opposite him.

At this moment, the five young wizards hadn't even finished half of their spells, and coupled with their lack of combat experience, they were simply standing still and attacking. They were all hit by the red light and knocked away.

Five wands flew high into the air and landed in front of Su Yu. The young wizards below were stunned; they never expected this outcome.

"Five against one, a one-second victory! Professor Su Yu is just too... too incredible!" A Gryffindor lion cub stood up excitedly.

The Slytherin snake also looked shocked: "No... impossible. Even if the professor is powerful, he couldn't possibly defeat five people in one second. That's not magic at all."

The Ravenclaw hawks were completely different. Su Yu was a graduate of the Hawkhouse and had earned the most points for Hawkhouse last week. Seeing Su Yu's performance, they immediately applauded and cheered for him.

The most shocked were the five little guys on the stage. They all came from wizarding families. Although their own magic level was not particularly high, they still had good eyesight. Even their own family elders could not defeat the five of them so easily.

In an instant, the five people looked at the magic pistol in Su Yu's hand with intense fervor and longing.

Su Yu clearly felt everyone's gaze, handed the five magic wands back, and said, "Don't get so excited, these things aren't as powerful as you think."

"First of all, the power of the spells it emits is much weaker than the spells you cast yourself. Secondly, you are still at the age of learning, and using it frequently will affect your own spell proficiency."

Then Su Yu changed the subject and said, "However, if anyone gets first place in the Muggle Research course exam at the end of this semester, I wouldn't mind giving him a magic pistol."

"Yay! That's mine!" The Weasley brothers were the first to jump up from the ground, waving excitedly.

The other children were also excited, but they were clearly not as carefree as the Weasley brothers; they simply made up their minds to work hard.

"Alright, next I'm going to show you an American movie called 'Once Upon a Time in the West.' I hope you'll enjoy it!"

After saying that, Su Yu took out a magic projector and started playing this classic American Western film in the classroom.

Although this movie is twenty years old and contains no magic, the free and unrestrained image of the Western cowboy is deeply imprinted in the hearts of every young wizard.

Tonight, almost all the young wizards dreamed that they had become a cowboy in the Wild West, wielding a pistol that could fire magic, and defeating the dark wizards.

Over the next week, Su Yu demonstrated the power of the magic pistol in classes from third to seventh grade, and discussions about Su Yu at school became rampant.

Some young wizards believe that Su Yu is an extremely powerful wizard who can defeat all enemies who offend him with his various magical alchemical tools.

However, some young wizards judged Su Yu's magical level to be quite average based on his performance in Transfiguration and Potions classes.

Since alchemical items are merely external objects and cannot represent one's magical level, they concluded that Su Yu was just a skilled alchemist, with only mediocre abilities.

The two factions were constantly arguing, with George and Fred being the representatives of the powerful faction. As Su Yu's prospective disciples, they were quite protective of their teacher.

The representative of the "weakling" faction is Marcus Flint, who is the prefect of Slytherin and also the captain of the Slytherin Quidditch team.

Marcus hadn't taken Su Yu's Muggle Studies course, and naturally hadn't seen the magic pistol, but he felt he could deduce from his imagination that Su Yu had only used some underhanded tricks to attract everyone's attention.

So on Friday night, in his Slytherin rest area, Marcus gathered his supporters and gave a loud speech:

"Everyone has probably heard about it, right? That new Professor Su Yu, a Muggle, is a professor who can only teach Muggle Research, a dispensable course."

"They actually claim to have developed an alchemical tool that can cast spells without the need for a wizard's incantation. How utterly laughable, hahaha..."

"Hahaha, that's right, utterly ridiculous..."

"A Muggle-born guy, who does he think he is, Dumbledore? How ignorant and arrogant..."

"This is the funniest joke I've heard all year. A wizard can cast spells without casting a spell. If what he said is true, then wouldn't Squibs be able to cast spells too?"

Many people below echoed his sentiments, loudly expressing their opinions and bursting into cheerful laughter.

“You are the ignorant and arrogant ones. You haven’t even seen Professor Su’s invention, yet you’re spouting nonsense here. Who gave you the courage?”

Just then, an untimely, clear, cold female voice rang out, drawing everyone's attention. The girl was about 1.65 meters tall and had shoulder-length blonde hair.

Her large wizard robes couldn't hide her hot figure, but a faint chill lingered between her eyes.

Marcus Flint was furious at Gemma Farley's sudden dissent; his fierce expression made his already protruding front teeth look even more menacing.

Although the Farley family was also pure-blooded, they were far inferior to the Flint family, one of the 28 pure-blooded families. This woman dared to oppose him! Marcus walked up to Gemma Farley, looking down at her condescendingly.

“Gemma Farley, what are you saying? Do you really think a lowly Muggle could invent such a revolutionary alchemical tool?”

"Have you forgotten the glory of pure-blood families? Have you forgotten who truly leads the magical world forward?"

"No wonder your Farley family is getting worse and worse. Why don't you just drop out of school, get engaged to me, and use the reputation of our Flint family to perhaps make you even more successful, hahaha..."

Marcus's words were extremely malicious for a pure-blood wizard, but none of the classmates watching came to Gemma Farley's aid; instead, they laughed along with Marcus.

In the case of an ordinary little witch, she would most likely have gone back to her dorm crying or told the teacher, but Gemma Farley was clearly not an ordinary little witch.

Gemma Farley must have had her own abilities to become a prefect in a house like Slytherin that values ​​bloodlines.

She wasn't angry; she just glanced coldly at Marcus, then looked around at everyone, neither refuting nor making any move. She simply watched them coldly, letting them laugh to their hearts' content.

As they laughed, everyone noticed something was wrong with Gemma Farley. When they met her gaze, the coldness and disdain she exuded made them stop laughing.

Marcus naturally noticed something was wrong, but as the leader, he couldn't back down. He stepped forward and continued to put on airs:

"What, are you tempted? Then hurry back to your dorm and write to your father. For the sake of our friendship, I wouldn't mind marrying you."

At this point, Gemma Farley finally spoke, giving a cold snort: "We take pride in our surname, but not in our noble status; we value strategy, but not in our impetuousness or underestimation of the enemy; we assess the situation and protect ourselves wisely."

"It seems you've completely forgotten Slytherin's house motto. The wizarding world has never been led by a particular surname, and the honor of pure-blood families is not defended by belittling Muggles."

"Your words only reveal your ignorance, weakness, and incompetence. You should be grateful that your ancestors left you a good surname, otherwise a fool like you would never be a Slytherin prefect."

Lies cannot hurt, but the truth is the sharpest blade. Hearing Gemma's words, Marcus Flint immediately lost his composure, drew his wand, pointed it at Gemma Farley, and roared:

"Who do you think you're talking to? Believe me, I can bankrupt your entire family with a single word!"

"Slug!" A voice suddenly rang out, and a beam of green light shot from the end of the passage, striking Marcus Flint directly.
