Being at Hogwarts, something's not right with this system.

"Actually, I'm annoyed too, Professor Snape. Why do you always like to pick fights? As a professor, a teacher, your students are as young as eleven. Is it really okay for you to be so willful? You seem a bit like a giant baby."

Lin Yu glanced at Snape, and his words became increasingly impolite.

Lin Yu simply couldn't stand it anymore.

Doesn't an adult feel ashamed for always arguing with and finding fault with children?

Isn't this just a complete overgrown baby?

Lin Yu could have ignored Snape's targeting of Harry.

The problem is, now they're the ones being targeted.

Then he wouldn't be able to tolerate it at all.

Whether it's Snape or Draco Malfoy.

Let's take it slow.

Just wait and see.

Turning around, Lin Yu went to the alchemy furnace, raised his hand with a hint of anger, and said in a low voice, "Open the furnace."

'Bang!'

As if even the alchemy furnace sensed Lin Yu's mood, it emitted a muffled thud, startling Fox.

Poor Fox, what business is it of a phoenix like me to deal with your human affairs?

As the alchemy furnace was opened, a fragrant aroma of elixirs immediately filled the entire office.

Snape ignored Lin Yu's words and stared intently at the nine crystal-clear pellets that had just been produced in the alchemy furnace. He even took out a glass bottle and handed it to Lin Yu.

Lin Yu accepted it with a complicated expression.

How should I put it? He was a complex person.

In his youth, Snape was obsessed with dark magic and genuinely followed Voldemort, but he was not a villain who did evil; rather, he had his own ideals and pursuits.

Just like his current philosophy on potions.

Even though he was facing the disliked Lin Yu, he was very curious and interested in Lin Yu's alchemy.

He would even proactively hand bottles to Lin Yu, including preparing glass bottles in advance.

He possesses a devout and sincere heart in the field he loves.

However, this did not prevent Snape from disliking Lin Yu and other students from non-Slytherin houses.

After all, this is the real world. In Lin Yu's eyes, Snape is no longer a character in a novel or a character in a movie, but a living, breathing human being with flesh and blood and complex emotions.

Lin Yu shook his head, put away his thoughts, and used his spiritual energy to put the Marrow Cleansing Pills into glass bottles one by one.

Turning around, Lin Yu showed Dumbledore the Marrow Cleansing Pill in his hand.

Dumbledore was about to reach out his hand.

Lin Yu dodged the attack with a flick of his hand, rolling his eyes and saying, "Principal Deng, you're not trying to get something for nothing, are you? I promised to demonstrate how I refine pills, and you don't think you can just take my Marrow Cleansing Pill by teaching me two basic defensive spells that I'll learn eventually, right?"

Do not make jokes.

Is the Marrow Cleansing Pill priced separately?

Dumbledore could only awkwardly withdraw his hand.

Lin Yu put the Marrow Cleansing Pill and the alchemy furnace back into his Qiankun Ring.

Since they are all wizards, it's not surprising that they use methods similar to magic or spells.

Therefore, Lin Yu was not worried that the storage equipment would attract much attention.

As expected, Dumbledore and Snape were not curious.

Lin Yu continued, "As you all saw with your own eyes, only I can obtain the materials for alchemy, and only I possess the formula. Therefore, I set the price for the Marrow Cleansing Pill. If anyone else, even someone from the Ministry of Magic, comes to inquire, you can tell them it's one thousand Galleons for one Marrow Cleansing Pill."

As he spoke, Lin Yu reminded Snape, "By the way, Professor Snape, you seem to still owe me a dose of Felix Felicis. I think two thousand Galleons should be enough to buy one dose."

Snape stared coldly at Lin Yu. Just when Lin Yu thought the other party wouldn't speak, Snape flicked the hem of his long robe and took out a small, transparent glass bottle.

It turns out that he had successfully concocted a dose of Felix Felicis over the past two days, Saturday and Sunday.

Snape truly lives up to his name; in the field of Potions, the young man has likely already become one of the authorities.

Even Dumbledore trusted him implicitly.

"Remember you promised me you wouldn't use it to cheat, and you absolutely mustn't let me find out you've used it for anything bad," Snape coldly warned Lin Yu.

Lin Yu snatched the Felix Felicis from Snape's hand, and at this moment he couldn't help but say sincerely, "Can't you also set an example as a professor? Dare you stop targeting me and us students who aren't Slytherin? Don't forget, above the four houses, we are all Hogwarts people."

Snape's lips twitched. What he really wanted to say was, if you annoying little lions didn't cause trouble, if you weren't stupid, if you could all listen to the lesson honestly and attentively, would I lose points?

After all, he only targets Harry Potter, since that's Pot's kid.

But when he thought of Harry being Lily's child, Snape could only silently clench his hands, which were hidden in his sleeves.

"Alright, Lin Yu, stop acting innocent after getting the benefit," Dumbledore couldn't help but scold. "Is that a Chinese proverb?"

Lin Yu shrugged: "I guess so."

Actually, this is a colloquial saying, and there is a difference between a colloquial saying and a proverb.

But he didn't want to explain the difference to an old British man.

"Then I'll use it now, so you won't suspect me of cheating," Lin Yu opened the glass bottle and, without hesitation, tilted his head back and poured it into his mouth.

He didn't hesitate at all, as if he wouldn't doubt Snape.

Snape's expression finally softened, though he wouldn't actually add poison.

However, Lin Yu and he were like oil and water, and they almost came to blows every time they met.

Snape was also puzzled. How could Lin Yu, a first-year student and an eleven-year-old child, dare to challenge his authority time and time again?

Strangely enough, although Snape was also very angry, he never thought of doing anything to Lin Yu, let alone kicking him out.

Perhaps it's because, although Lin Yu argued with him face-to-face, he actually showed sufficient respect and politeness to each professor.

He always tries to reason with people first, and only resorts to insults when reasoning fails.

Unaware of Snape's thoughts, Lin Yu immediately took his leave after drinking the Felix Felicis, saying, "I have to go now."

Dumbledore said quietly, "Going to your secret base again?"

The Room of Requirement is on the eighth floor, and there is a portrait passage in the Hog's Head that leads to a specific Room of Requirement. The owner of the Hog's Head is Dumbledore's brother.

So how could Dumbledore not know about the existence of the Room of Requirement, and how could he not know about Lin Yu's little tricks at night?

He just didn't know how Lin Yu discovered the House of Requirement, or what he did there.

Lin Yu didn't care whether Dumbledore already knew about this. Taking advantage of the time when the Felix Felicis started to take effect, he ran out of the headmaster's office, quickly opened the small door of the Room of Requirement, and hid inside.

Looking in the direction Lin Yu left, Dumbledore turned to Snape and sighed, "He still respects you very much, Snape."

Snape scoffed. "Stop your little tricks, Dumbledore. Do you think I can really get rid of him? I don't have that authority."

Ignoring Dumbledore's awkward smile, Snape turned and walked away without any politeness.

After all, Dumbledore threatened and manipulated him, but ultimately failed to protect Lily. Now, he wants to continue using that child, Lily's child, to threaten and manipulate him.

It would be strange if Snape had a good impression of Dumbledore.

But Dumbledore didn't seem to care at all; on the contrary, he seemed to dote on him.

Is this some kind of inhuman pampering?

Or rather, Dumbledore's trust in Snape is often incomprehensible.
