Harry Potter: This senior is pretty strong

"Aragok is back," Hagrid said to Qin Yu with a relieved but apologetic tone.

The man had just returned from the forbidden forest, and his thick coat still seemed to carry the chill of that mountain forest.

"Huh? Who?" Qin Yu, who was grooming the unicorn Kelly's mane, didn't react for a moment after hearing Hagrid's words.

“It’s that old eight-eyed giant spider that escaped,” Hagrid explained, stretching out his hands and grabbing at them, mimicking the eight legs of the eight-eyed giant spider.

Qin Yu removed the unicorn hairs hanging from the comb one by one and handed them to Fred, who was standing next to him, so that Fred could collect them carefully. Then he nodded in realization and said, "So that's it... Didn't they say that the old guy ran away from home?"

To be honest, Qin Yu didn't have a good impression of this eight-eyed giant spider. He had clearly explained to it that he was Hagrid's friend when he accidentally entered the spider's cave, but the guy still let his offspring commit atrocities.

If it were someone without a system, wouldn't they just be stuck there?

The old creature might not hurt anyone, but its indifference when it saw Qin Yu and the little unicorn in danger that day still bothered Qin Yu. That's why Qin Yu always referred to it as "it".

“Well, Aragog didn’t have a good time after he escaped. He was almost killed when he passed through the centaur settlement… Now that the weather is getting colder, he quietly came back. I only found out when I went to patrol the Forbidden Forest just now.” Hagrid added after saying this, “He specifically told me not to tell you that he’s back.”

"..." George.

"..." Fred.

"Didn't I tell you not to tell Qin? Why did you still tell him?" The two brothers muttered to themselves at the same time.

"Hmph, does it think it's afraid of me eliminating it completely?" Qin Yu said irritably.

“That’s probably the concern. Aragog said you were terrifying back then, and if he hadn’t run away in time, he would definitely have died too…” Hagrid nodded in deep agreement.

Qin Yu rolled his eyes, and while giving Unicorn Kelly a middle parting hairstyle, he said coldly, "Go tell it that since it didn't hurt me back then, I won't hurt it either. By the way, tell it that this is because of Uncle Hagrid. Also, its offspring and descendants brought this upon themselves, and their corpses belong to us. If it has any objections to this, I can talk to it."

George and Fred nodded vigorously in agreement. The venom of the eight-eyed giant spider was quite popular, and they already had wizard clients as far away as Brazil.

“I can assure you that Aragog will have absolutely no objection to this. His children are wild and untamed, completely different from him, and even he himself has a hard time controlling them,” Hagrid said to Qin Yu and the Weasley brothers.

Qin Yu roughly understood what Hagrid was saying. Aragog was raised by Hagrid, much like a husky raised in the Muggle world. Although fierce, it was obedient to human speech. In contrast, Aragog's children were all wild, ferocious and ignorant beasts, like wild dogs and wolves.

One is a pet, the other a wild beast. Hagrid naturally has feelings for Aragog, but he feels no sympathy for those wild beasts. Aragog is the same; after all, he has too many descendants, so what is there to sympathize with?

"Well, that's all then. Just let it continue living in its old den." After saying this, Qin Yu seemed to remember something and then said to Hagrid, "Tell it that if any of your friends come in, make sure it keeps a close eye on its little ones. If any of them hurt anyone, I don't mind blowing up the spider's den again. Then we'll see if it can escape successfully once more."

Qin Yu certainly wouldn't use the power of the Silent One to blow up the spider cave, but he could still scare it. It's just a big bug; does it know the idiom "all's fair in war"?

“I will definitely pass on the message,” Hagrid said solemnly upon hearing this.

……

Qin Yu and his companions obtained the venom and used it to make a small inroad into the magical world's market. Aragog also received Qin Yu's temporary forgiveness and warning after Hagrid's "lobbying." The Eight-Eyed Giant Spider incident can be considered to have come to a satisfactory conclusion—or so it seems.

George and Fred were relieved, and Hagrid returned to the Forbidden Forest to tell Qin Yu what Aragog had said.

The only one who was dissatisfied was Anna, the little unicorn.

While Qin Yu was grooming the giant unicorn's brown fur, she had already been circling around it impatiently.

Hagrid's appearance directly slowed down Qin Yu's progress in styling her mother's hair, which made her somewhat angry.

Hagrid finally left, and Qin Yu styled Unicorn Kelly's hair into a middle part that would satisfy even someone with OCD. Then, the little unicorn quickly came over and asked Qin Yu to do her hair too.

Seeing her like this, Qin Yu couldn't help but smile.

So he removed the last of the white unicorn hairs from the comb, handed them to the Weasley brothers to keep, and then began to groom Anna, the little unicorn. The Weasley brothers were not accepted by the unicorns for grooming their brown fur.

—As for the golden unicorn hair that comes off, there's no need to collect it. Well, Ollivander doesn't collect anyone's.

However, while Qin Yu was grooming her fur, the little unicorn kindly reminded him with her eyes to collect her golden fur as well.

To prevent Anna from feeling that her fur was less useful than her mother's, Qin Yu had George and the others put the golden animal fur in a different bag.

Friday afternoon passed just like that.

Qin Yu spent half a day with the unicorns, grooming their manes, enjoying a moment of leisure. Meanwhile, the brothers George and Fred were quite satisfied with the unicorn hair they had collected.

Then, after Hagrid returned from the Forbidden Forest with Aragog's guarantee, Qin Yu and the Weasley brothers left Hagrid's Hut and returned to Hogwarts Castle.

……

On the way back, George and Fred walked ahead, while Qin Yu followed behind, strolling slowly and thinking about recent events.

Then, he unexpectedly thought of the old eight-eyed giant spider Aragog. Thinking of Aragog, Qin Yu naturally thought of the system that had saved his life.

Speaking of which, since the Eight-Eyed Giant Spider incident, this system seems to have been silent, and no one knows where it went.

Could it be that the bill is overdue?

Thinking of this, Qin Yu couldn't help but stop and silently prayed, "System, system, are you still there? If you are, please say something!"

After waiting for five seconds, Qin Yu received no response.

Just as he was about to step away, a voice suddenly rang in his mind:

"squeak--!"

"..." Qin Yu.

Qin Yu was speechless for a moment. After a while, he said helplessly in his heart, "Your work efficiency has been poor lately. How long has it been since you issued a selection task?"

I have no extra income; I rely entirely on hard work to earn money, which is really tiring.

"Ding! We have detected a strong desire for adventure in the host. Would you like to activate the S-level difficulty world mode?" the system voice announced.

"S-level difficulty world mode? What the heck?" Qin Yu was somewhat surprised by the system's words.

“In this mode, the world will descend into the highest level of chaos. In that case, the host will be in constant danger, and I will be able to issue selection missions frequently,” the system explained in a mechanical voice devoid of any emotion.

"...You mean, as long as I want to do something stupid, you'll appear with a mission selection option?" Qin Yu was stunned for a long time before smacking his lips a few times and asking.

The system replied: "Your understanding is accurate. Would you like to activate S-level difficulty world mode? You have five seconds to make a choice. If you do not respond within the allotted time, it will be activated by default. The five-second countdown has begun: 5, 4, 3..."

"Damn it, open it my ass! I won't open it!" Qin Yu said urgently.

Good grief, I was doing just fine, and you give me an S-level difficulty challenge? Do you think I'm not lucky enough to survive?

"Ding! Host's reply has been received. The current difficulty world mode will be maintained for now!" the system notification sounded.

Then, the system added, "If the host wishes to unlock a higher difficulty level of the world mode, please summon me at any time!"

Upon hearing this, Qin Yu rolled his eyes: "I don't have masochistic tendencies, why would I want to use a high-difficulty mode?"

"Then don't summon me," the system replied.

"Hmm, okay... wait a minute, why does that sound like it's tinged with emotion? Are you trying to argue with me?" Qin Yu asked excitedly.

"..."

"Do you have emotions similar to those of humans?" Qin Yu continued to ask.

However, the system did not respond at all, not even making a sound.

After trying for a while, Qin Yu decisively gave up, because he was really afraid of angering the system. If it directly set an S-level difficulty mode, it would be enough to give him a hard time.

At least, he is quite satisfied with his current life and doesn't need any more challenging tasks.

The cold evening wind blew across the hillside, and Qin Yu shivered and huddled up.

He hurried a few steps to catch up with George and Fred, who were calling out to him from afar.

……

Sitting at the dining table, after drinking some hot tomato soup, Qin Yu felt very comfortable, his whole stomach feeling warm and cozy.

After eating two pies and a potato, Qin Yu left the auditorium and went to the Defense Against the Dark Arts professor's office on the third floor.

The place became very crowded after Professor Swinton decided to teach Qin Yu alchemy, filled with all sorts of alchemical materials and tools.

After Qin Yu knocked and entered, Professor Swinton said with a smug look, "You've come at the right time. I've cracked the material formula of the Egyptian Alchemy Research Center, and we can start refining it now!"

(I had a bit of writer's block, so I flipped through the book, looked up some information, and sorted out the plot, which took up some time.)

Then, thank you all for your encouragement, comments, and donations. Your kindness makes this humble author feel incredibly honored, and I will do my best to write this book well!
