Harry Potter: This senior is pretty strong

The Disguise Charm is a disguise spell that allows the caster or object to blend in with their surroundings like a chameleon, including in terms of color and texture.

More advanced Disguise Charms can also conceal the target according to the caster's needs, such as removing the wings of a Pegasus, so that Muggles won't notice the Pegasus's special features, and the wizard who raises the Pegasus won't be exposed.

As for the high-level Illusion Spell, it is said to achieve the effect of invisibility, which is equivalent to wearing an invisibility cloak.

It sounds impressive, and it's indeed very difficult to execute. Dumbledore could definitely do it, and even someone of Snape's caliber could achieve some degree of invisibility, but it certainly wouldn't be as perfect as Dumbledore's.

Qin Yu had practiced this spell under Snape's guidance, but it wasn't very successful; he could only barely make the colors match the environment.

In short, a high-level Illusion Charm is a very valuable spell, equivalent to having an invisibility cloak!

How could Qin Yu not be tempted by such a reward from the system? He knew that if he relied solely on his own practice, it would probably take him two or three years to master it. The system's reward directly shortened that time.

Faced with the system's two options, Qin Yu would have definitely chosen option two if he hadn't brought Hermione with him. However, with Hermione present, he hesitated somewhat.

Perhaps choosing option one wouldn't be bad either, Qin Yu thought to himself.

"Qin, what's wrong? Are you thinking about something?" Hermione glanced up and noticed the thoughtful expression on Qin Yu's face, so she asked curiously.

"I suddenly remembered I have something to do in Diagon Alley... but it's okay, it's not urgent," Qin Yu said casually.

"Hmm? Then go ahead and do it. There's nothing else to do right now. Besides, don't you always say that if something has to be done, there's no need to make excuses to put it off? — Have you forgotten what you taught me?" Hermione said seriously.

Hearing her words, Qin Yu was momentarily stunned.

Yes, some things can't be avoided, and there's no point in dragging them out.

As a time traveler, he should understand this principle even better, because he knows just how difficult the future will be.

Perhaps his peaceful life had numbed him, making him almost forget that he had to make a lot of effort to change his future.

Then, his gaze hardened, and he nodded, saying, "You're right. Some things can't be avoided, and there's no need to drag them out."

"Hmm." Hermione nodded with a smile, feeling she had finally given Qin a lecture. Then, she asked, "Do you need me to come with you?"

"No need, you can stay here and read. It's more convenient for me to do this by myself," Qin Yu said, shaking his head.

Qin Yu definitely couldn't take Hermione with him on the investigation, and it was quite safe for her to stay at Flourish and Blotts.

"Okay, okay." Hermione replied obediently, though she was slightly disappointed.

Then she pointed to the empty glass, bit her lip, and said somewhat shyly, "Um... Qin, can I have another glass of juice?"

"Of course, no problem. I'll go find the owner and ask her to bring up a cup. Then, I'll leave some money with her. Just tell the owner what you want to buy," Qin Yu said with a smile.

“That’s great, thank you, Qin!” Hermione said happily.

"Don't be so polite with me." Qin Yu stood up, gently rubbed Hermione's head, and then quickly went downstairs.

"Choose [two]!" Qin Yu silently recited in his mind.

"Ding! Your choice is courageous. Please complete the investigation as soon as possible. Good luck!" the system replied.

After Qin Yu stepped downstairs, he looked back at Hermione, who was quietly and attentively reading by the window. Hermione seemed to sense his gaze, tilted her head to look at him, then gave him a bright smile and waved to him, indicating that he should focus on his work, come back quickly, and not worry about her.

Hmm, she's such a lovely, sensible, and understanding older... uh, younger sister.

Qin Yu waved goodbye to Hermione again and then walked down the stairs.

After leaving behind a pile of Galleons and instructing the shopkeeper to give Hermione a glass of exotic juice, Qin Yu hurriedly went out to find the young man.

In fact, from the time he spotted the suspicious man to the time he went downstairs, not much time was wasted. In addition, the man's movements were relatively clear, and Qin Yu quickly spotted him.

Then, he carefully followed behind the man, maintaining a safe distance.

Qin Yu followed him for a while and saw the man stroll around the crowded streets, but his expression and movements were somewhat tense, clearly indicating that he had no intention of buying anything.

About ten minutes later, the person glanced at the magic clock in a shop, quickened his pace, and hurried away from the bustling street, walking towards the quieter side of the street.

Finally, at some point, his figure suddenly disappeared.

Qin Yu quickly approached and discovered that the person had turned into a narrow, deserted alley.

Then, the young man stopped in the alley, looking somewhat anxious, as if he were waiting for someone.

Since the alley was short and had two ends, Qin Yu didn't guard the alley entrance to avoid being discovered by this person or anyone else who might appear. Instead, he went to a big tree next to it, climbed up, and waited there.

Although it was winter, the tree was lush and leafy, suggesting it was some special species. Qin Yu was hidden in the canopy, making it difficult for outsiders to notice his presence at a glance.

Nearly ten minutes later, just as the young man in the alley was pacing impatiently, someone appeared at the opposite alley entrance and clearly walked towards him.

Upon seeing this, Qin Yu quickly and carefully slid down from the tree, then swiftly and lightly approached the alleyway entrance. He stopped beside a pile of debris, using a broken wooden plank to conceal himself. Then, he cautiously peered through the gaps in the plank at the two people not far away.

"You're too late! You have absolutely no sense of time!" the young man said with displeasure.

"You insisted on meeting here, and I was afraid of running into acquaintances, so I had to take a detour," the man said helplessly.

The man who came later was wearing a dark cloak, his face covered by the cloak's hood, so Qin Yu couldn't see his face clearly. Judging from his voice, he was probably a man in his thirties.

“You could have come here earlier…and meeting here is the safest option for both of us,” the young man said impatiently.

“Honestly, we should trust each other more, 'for the greater good,' and so should we,” the cloaked man said.

"Forget it, we're different from you. At least, we don't discriminate against our fellow wizards because of our bloodline," the young man said with a cold snort.

"Alright, alright, let's put this ideological debate aside for now. At least we have a need to cooperate now, don't we?" The cloaked man's tone softened.

"Well, I have no objection to the cooperation... Of course, I'm not the one who can make the decision..." The young man stopped being confrontational.

Then, the cloaked man extended a hand and handed over a key: "Well then, let's get down to business. We think the stuff is acceptable, and this is the payment for the second portion."

The young man took the keys and handed over a small bag.

The cloaked man took the bag, untied the drawstring, looked down at it, and then said with satisfaction, "Good, it's a pleasure doing business with you."

He extended a hand, and the young man shook it somewhat reluctantly.

However, just then, a commotion at the alley entrance startled them.

First came a meow, then someone cried out in pain, followed by a loud crash like a wooden plank falling.

"Who?" "Who is it?"

The two exclaimed in surprise at the same time and quickly pulled out their wands.

When they saw a figure appear at the alley entrance, they simultaneously waved their wands at each other.

However, the two of them had only recited half of their incantations when the opponent's spell struck them first!

"Expelliarmus!"

Clang! Clang!

Two sounds followed, like wands falling to the ground.

This caused the two people in the alley to show expressions of fear. Their opponent was not only very strong, but also decisive in his actions; he was clearly not someone to be trifled with.

"Let's talk this out..." the cloaked man pleaded.

"Stupefy (collapsed)!"

Before the cloaked man could finish speaking, the opponent's second wave of spells had already attacked.

The cloaked man and the young wizard immediately collapsed to the ground.

Nearly a minute later, the figure at the alley entrance slowly approached and cautiously kicked each of the two men on the ground once.

"Phew, looks like everything's fine now." The voice sounded a bit childish.

After he removed the disguise spell, he revealed a face with delicate and handsome features that had Eastern characteristics.

That's right, this person is Qin Yu, who was tracking and investigating the suspicious man.

Unfortunately, the place he had just hidden was a stray cat's "home." When the stray cat returned home and discovered an uninvited guest, it immediately attacked him.

Qin Yu was focused on the two people in the alley when, caught off guard, his hand was scratched with four bloody cuts.

He cried out in pain, and the wooden plank in his hand fell to the ground. How could this commotion not alert the two men?

Qin Yu, having gone this far, decided to go all the way. Relying on the reaction speed he had developed under Professor Snape's tutelage, he cast the spells "Remove Weapon" and "Stun" in quick succession, quickly taking down the two men in the alley.

—The "Binding Law" is actually mainly aimed at situations where spells are cast in front of Muggles. In places like Diagon Alley, where wizards are the main characters, Qin Yu can cast spells with peace of mind.

"Can we talk this over? What do I have to talk to you about..." Qin Yu said coldly.

The world is dangerous; he'd rather take them down first than have any further conversation afterward.

Then, Qin Yu pulled open the sleeves of the two men and saw a pattern made up of "triangles, circles, and vertical lines" on the back of the young man's wrist.

Yes, this is the legendary symbol of the Deathly Hallows, and also Grindelwald's emblem.

On the inside of the other person's wrist was a bright red tattoo of a python emerging from the mouth of a skull.

Upon seeing the second pattern, Qin Yu felt a chill run down his spine.

Merlin's legs! A Death Eater and a Gazette (GA), do you really have to gather them all at once?

As Qin Yu sighed, he picked up the keys and bags from the two men's hands and stuffed them into his pocket.

Hearing faint voices, Qin Yu wasn't sure if they were passersby. He didn't linger, since he couldn't take the two people on the ground with him anyway. He quickly walked out of the alleyway he had just entered.

……

……

"Wow, Qin, where did this kitten come from?" Hermione's eyes instantly softened with tenderness and adoration when she saw the little yellow kitten Qin Yu was holding.

There's no way around it; girls can hardly resist the cuteness of small animals.

"Sigh, I found it on the street. It seems to be a stray cat. I just cleaned it up... I'm planning to take it to a pet store later, but I don't know if they'll accept it," Qin Yu said helplessly.

Although the cat attacked him, it had taken over the cat's nest first and seemed to have crushed the kitten's toy—a very broken wooden puppet.

As he left the alley, the little yellow cat looked at him and trembled, probably realizing that the boy was a very powerful and terrifying person.

Qin Yu felt sorry for it, so he casually cast a cleansing spell on it and brought it back.

"Can I hug him?" Hermione asked, her eyes full of anticipation.

“…Okay, but you have to be careful, it just scratched my hand,” Qin Yu warned.

"Oh? Are you alright?" Hermione asked worriedly, looking at Qin Yu's hands.

"It's all better now. I've already bought a special potion to heal it at the potion shop." Qin Yu showed Hermione the back of his injured hand.

After treatment with healing spells and special potions, there were no obvious marks left on him.

Hermione was relieved, and then began to scold the little yellow cat: "How could you bully Qin? He's a very kind and gentle person. Look, he even brought you back..."

The little yellow cat made whimpering sounds after hearing Hermione's words, it's unclear whether it understood what "gentle and kind" meant.

The two were on the first floor of Flourish and Blotts. Since Qin Yu had left some money and asked Hermione to keep an eye on things, she carefully selected a few books and had the shopkeeper put them in a canvas bag.

When Qin Yu returned, the bookstore owner gave him back the remaining pile of Galleons.

Looking at the pile of Galleons that hadn't decreased much, Qin Yu thought to himself, "This girl is really good at managing money; she knows how to save me money."

Then, Qin Yu carried the bag of books, and Hermione held the little yellow cat as they left Flourish and Blotts.

"Huh? Why did you buy this book too?" Qin Yu glanced at the books in the bag on the way and said with some surprise.

“I noticed you’d been looking at this book, and the shopkeeper said it’d been sitting in the store for ages without anyone buying it, so it was on sale for only 5 psi, and I bought it too.” Hermione said, then added somewhat awkwardly, “Don’t you like this book?”

"No, actually this book is quite good, with some originality, and at 5 sq ft, it's a great deal! We definitely made a profit by buying this book at such a cheap price," Qin Yu said with a smile.

"Hehe, that's good!" Hermione laughed along.
