Harry Potter: This senior is pretty strong

"A fine sword!"

When Professor Swinton pulled out—or rather, drew out—that longsword gleaming with metallic luster, Qin Yu couldn't help but exclaim in admiration.

This sword is different from the common Western rapier; it is a broadsword that looks very heavy.

The sword has sharp, angular lines, and its surface has been specially treated to be smooth and reflective.

Judging by its appearance alone, it's already quite good.

"This sword, I borrowed the flight principle of a flying broom, and with the addition of an extension spell, can change size and even fly..."

As Professor Swinton spoke, he threw the sword out, chanted a spell, and the sword grew larger and wider.

"Up!"

As the classic broomstick command rang out, the sword gently floated up and hovered there.

“Step on it!” Professor Swinton said to Qin Yu.

"Are you sure this is okay?" Qin Yu asked.

"I can't possibly be the one to fly this sword for the first time, can I?" Professor Swinton said with a shrug.

"..."

Is it appropriate for you to say that to a child like me? Qin Yu couldn't help but think to himself.

Then, he moved his hands and feet a few times to warm up, and then jumped up lightly and landed on the sword.

As soon as he stepped on it, a suction force instantly pulled his feet in place, allowing him to stand steadily on it.

This is clearly a special absorption spell!

Sure enough, Professor Swinton, seeing the surprise on Qin Yu's face, said with a touch of smugness, "I've gone to great lengths to prevent you from falling from the sky."

Qin Yu gave Professor Swinton a thumbs up.

The subsequent flight was similar to using a flying broomstick. Qin Yu already had experience in this area, except that this time he was flying standing up, which required some getting used to.

He lowered his body slightly, controlling the sword to fly forward. Just before it hit the wall, he stopped in time, turned, and then turned back.

After repeating this several times, Qin Yu had become quite adept at it. Although he wasn't as skilled as when using the flying broom, he could still move as fast as the wind.

Seeing how quickly Qin Yu mastered the flying sword technique, Professor Swinton couldn't help but sigh inwardly, "Qin really learns everything very quickly."

Then, he couldn't help but feel a little disappointed, thinking to himself that it would be great if he could teach him for a while longer, as he still had many interesting things he wanted to teach him.

However, I had only come to this school temporarily and was destined to leave.

Thinking about this, Swinton felt rather complicated.

"Roar!" Qin Yu performed a difficult aerial flip and let out a joyful cheer.

"Alright, if you keep practicing like this, you're going to tear this place apart!" Professor Swinton said with a smile, though he was annoyed.

"Hehe, sorry, Professor, I lost control of my emotions a bit." Qin Yu stopped steadily next to Professor Swinton.

"Come down, there's more." Swinton beckoned Qin Yu to come down.

"Hmm? Something else? Is it used to cut something?" Qin Yu asked curiously.

“More than that—” Professor Swinton left the audience in suspense.

Qin Yu jumped down happily and stood to the side, full of anticipation.

Professor Swinton then restored the sword to its original size and held it firmly in his hand.

"Watch closely!"

After saying this, Professor Swinton softly chanted a spell, and his longsword burst into flames with a loud bang.

Upon seeing this, Qin Yu's eyes widened instantly.

This effect is so cool!

No man could resist a longsword that spews flames!

"I got a few phoenix feathers from Professor Dumbledore, and they seem to be working quite well," Professor Swinton said, raising an eyebrow with a hint of pride.

"Not just good, it's beyond imagination!" Qin Yu didn't hold back his praise.

"besides!"

After Professor Swinton finished speaking, he swung his longsword, and the flames vanished instantly, with a layer of frost quickly and crisply forming on the blade.

He looked around, then swung his frost-covered longsword at his desk, and a corner of the desk separated from the body and crashed to the floor with a thud.

“That’s the effect of those ancient incantations,” Professor Swinton explained.

That's right, it's the ancient incantation they used to make the pyramid refrigerator, which he cleverly applied to this sword.

"Amazing!" Qin Yu clapped his hands in praise.

"besides!"

Professor Swinton continued to shake his longsword, and a green light gradually appeared on the blade.

"This is... the venom of the eight-eyed giant spider?" Qin Yu guessed subconsciously.

"Haha, you have good taste," Professor Swinton said with a laugh.

"This is very useful!" Qin Yu exclaimed.

"besides!"

The green light faded, and the air around the sword churned, creating a sharp gust of wind.

"besides!"

The wind subsided, and the sword emitted a dazzling white light.

"besides!"

The sword's color changes rapidly, blending seamlessly with its surroundings and becoming indistinguishable from the surrounding environment.

"besides!"

The sword softened and wrapped around his arm.

"besides!"

"besides!"

"besides!"

With each exclamation of "There's more!", Professor Swinton demonstrated the sword's various functions to Qin Yu, showcasing the boundless imagination and exceptional talent of a genius wizard.

In the end, Qin Yu stopped expressing his feelings and agreeing with the professor's comments, and instead watched Professor Swinton's demonstration quietly, as if he were watching a wonderful performance.

Yes, isn't a wizard with exceptional abilities just an artist who manipulates magic?

Of course, while admiring it, Qin Yu couldn't help but wonder how many Galleons it must have taken to achieve these functions.

Professor Swinton certainly comes from a wealthy family! His financial power is also quite impressive.

"Alright, that's about it." After the demonstration, Professor Swinton sheathed his sword and said to Qin Yu.

"Professor, I remember I made a lot of requests before, but you didn't agree to any of them. How come you made more requests than I did?" Qin Yu couldn't help but ask.

"How can these be the same?" Professor Swinton raised an eyebrow and continued, "Your demands are wishful thinking! My actions are a pleasant surprise!"

"..."

Upon hearing this, Qin Yu was speechless.

Then, I realized that Professor Swinton's words actually made a lot of sense.

"The only drawback is that many of these functions can only be used once or twice and cannot be used again for a short period of time. This is related to the operation of magic. After all, according to the law of conservation of magic, you have to consume the corresponding amount of magic power to achieve a certain effect. This is an insurmountable rule," Professor Swinton said with some regret.

To put it bluntly, it means you don't have enough magic power, or to use game terminology, well, you don't have enough mana.

"This is already very good, it really exceeds my expectations!" Qin Yu said again.

“Then, it’s your turn.” Professor Swinton handed the longsword to Qin Yu.

Qin Yu accepted it with great excitement.

……

The professors, of course, all knew that Qin Yu had finally obtained a sword that he could ride (or fly on).

After all, Professor Swinton had consulted with many other professors about modifying this sword.

Not to mention borrowing the phoenix feather from Dumbledore, Professor McGonagall contributed a series of ideas related to Transfiguration Charms, Madam Hooch's understanding of the structure of flying brooms was of great help, and Professor Flitwick's knowledge of Charms and Professor Sprout's knowledge of herbalism were also applied to this sword.

Of course, the most important contribution was Professor Snape's. He was involved in the design and modification of the sword almost from start to finish, and he always said things like, "That kid Qin likes to show off, you should do this and that."

Therefore, after obtaining the sword, Qin Yu thanked each professor in person.

Then, one day, Professor Dumbledore, despite his busy schedule, took the time to visit the Defense Against the Dark Arts teacher's office and personally examine the sword's effects.

"This reminds me of the Sword of Gryffindor!" Dumbledore gave it a very high evaluation.

Then, Old Deng said with some regret, "However, this sword still lacks some opportunities to become a legend."

"What was the trigger?" Professor Swinton couldn't help but ask curiously.

"Hmm... I don't know either," Dumbledore said with a smile.

Professor Snape, standing to the side, looked at Dumbledore's smiling eyes with a thoughtful expression.

Qin Yu thought to himself, "Hearing your words is truly like hearing a single sentence."

Of course, he wouldn't dare say that out loud.

Then, Qin Yu opened the large pyramid that Professor Swinton had been keeping, took out a chilled drink, and handed it to Professor Dumbledore.

Dumbledore took a few sips, nodded in approval, and said, "Not bad, not bad. The weather is getting hot now, so this is very refreshing."

After finishing his drink, before leaving, looking at the large pyramid in the corner, Old Deng casually remarked, "The alchemical materials are excellent, but using them to preserve food is too extravagant."

Upon hearing this, the three people present immediately lost face.

Even Professor Snape, who was always as cold as ice, couldn't help but twitch his lips a couple of times.

As the saying goes, "Don't hit someone in the face, and don't expose someone's shortcomings."

After saying this, Professor Dumbledore simply walked away as if nothing had happened.

The three people left in the room stood there awkwardly.

After a long silence, Professor Swinton spoke first: "Qin, how about..."

"Shh!"

Before he could finish speaking, Qin Yu swiftly drew his sword.

Professor Snape then opened the pyramid and took out its contents one by one.

Then, a flash of cold light appeared, and with a loud crash, the pyramid split in two.

The three people present all breathed a sigh of relief at the same time.

“I think these alchemical materials have many uses,” Professor Swinton said seriously.

“That’s right, that’s right.” Qin Yu nodded.

“Hmm,” Professor Snape echoed.

"Whatever you do, it's more useful than building a pyramid refrigerator," Qin Yu added to himself.

He had actually wanted to say this for a long time, and Professors Snape and Swinton had similar thoughts, but they were too embarrassed to say it. After all, this was something they had worked on for a long time with great seriousness. He didn't expect that Dumbledore would point it out today.

Now that a consensus has been reached, let's start from scratch and start over.

"Then what should we do?" Qin Yu asked.

Professor Snape and Professor Swinton both looked at him and at the sword in his hand.

Then, the two looked at each other again, their thoughts coinciding.

……

Soon, it was the end of May.

The Hogwarts school year is drawing to a close; courses are mostly finished, and final exams are about to begin.

Before the exam began, Snape and Professor Swinton had also completed their respective closed-door studies.

Qin Yu was also present when the two swords, each with a different shape, were placed together.

Then, as if possessed, he also pulled out his own.

The three swords clashed together with a clang, resonating as if connected by blood.

They come from the same source and seem to have some kind of mysterious connection.

"Haha, this is truly an interesting thing," Professor Swinton remarked with a laugh.

"Hmm, I didn't expect it to have such an effect," Qin Yu added.

“It’s not surprising that there are some connections between them since they are made of the same material,” Professor Snape said, sheathing his classically styled rapier.

Then, he said in a calm tone, "Stephen, when do you plan to leave?"

“…Severus, did you have to ask such a question at such a happy moment?” Professor Swinton sighed.

"Since parting is inevitable, why avoid talking about it?" Professor Snape rarely spoke so emotionally.

Qin Yu had actually fallen silent as soon as Snape asked his first question.

Since enrolling, Professor Swinton has been dedicated to helping and guiding him. Sometimes, Qin Yu even regards him as an older brother with whom he can talk about anything.

Now that they are about to part ways, he is naturally filled with mixed feelings.

Life is probably just a series of partings. Qin Yu thought to himself.

“Alright, let’s say goodbye then. Today, let’s have a drink to mark our parting.” Professor Swinton brought out a bottle of quite old red wine.

He and Snape each poured themselves a glass.

Because Qin Yu was too young, even though he was tempted, he was still firmly refused by the two of them. He could only drink a kind of "alcohol-like" drink that tasted similar but did not contain alcohol.

This "alcohol-like" drink can also have an intoxicating effect, but it is different from real alcohol.

Then, the three of them raised their glasses in this office to say goodbye, drank one glass, and then poured another—because there seemed to be too much to say about parting.

When all three of them were "drunk," Qin Yu patted the two professors on the shoulders and said rather emotionally and indistinctly, "Professors, I... I have an idea, but I don't know if I should say it or not!"

"Speak! Say whatever you want!" Professor Swinton, also quite drunk, said with a wave of his hand.

“Speak, I promise I won’t scold you today,” Professor Snape assured him.

His face was slightly flushed, and his eyes were somewhat glazed. Fueled by the alcohol, his thoughts seemed to drift into a distant memory.

Having obtained the two professors' approval, Qin Yu chuckled and said, "Here's what I'm thinking: you see, we're destined to meet here, and we all have a sword. In the Muggle world, we're the legendary Three Musketeers!"

“Yes, I’ve heard that story before!” Professor Swinton chimed in.

"Then why don't we become sworn brothers?" Qin Yu said, looking at the two of them with a slightly bright but dazed expression.

"Sworn brothers?" Professor Swinton asked, bewildered.

"Yes, from now on, we are half-brothers! Of course, we can call each other what we want. I'll call you professors, and you can call me third brother!" The "drunk" Qin Yu thought his idea was absolutely brilliant.

"Good, good, third brother! You are my own brother!" Professor Swinton patted Qin Yu on the shoulder and said.

"Huh? Third brother?" Snape called out blankly as well.

"Hey! Big brother, second brother!" Qin Yu happily put his arms around their shoulders and replied.

Then, the three of them continued to clink glasses.

Tonight is for farewell, tonight is for our past encounter; let us drink until we're drunk, let us drink until we're absurd.

——Dimensional wall——

The initial idea was that the pyramids would serve a certain purpose, but later, the idea was to split them up and make three swords, which could be seen as a bond between the three people.

Then, Qin Yu, after all, is an adult, so it's normal for him to treat the two professors as older brothers.

Okay, I haven't been feeling well lately, so my writing hasn't been very smooth. Please bear with me.
