For the next few days, Chen Yu followed his timetable, attending classes like the other Little Wizards of Gryffindor.

The Herbology professor was Pomona Professor Sprout, a short witch with wispy grey hair.

During class, she would take the Little Wizards to the Greenhouse behind the castle to learn how to cultivate these strange plants and fungi, and understand their uses.

Professor Sprout's classes were relatively relaxed for the Little Wizards.

As long as they followed her instructions and avoided touching the moving plants, they were fine.

Chen Yu listened to Professor Sprout's lecture while scribbling furiously.

He was curious about what those red and green fungi, which Professor Sprout called non-toxic, would taste like, especially in a hotpot.

The taste must be excellent.

Chen Yu loved eating fungi: shiitake, flower mushrooms, button mushrooms, and common mushrooms – he enjoyed all types of fungi available on the market.

However, the saying 'red umbrella, white stem, eat together, lie on the board' holds true; most red and green fungi in reality are poisonous.

According to someone at his workplace who also enjoyed fungi, brightly colored fungi are indeed fresh, but also truly poisonous.

If that person hadn't prepared beforehand and been rushed to the hospital in time, he might not have been saved.

Since then, Chen Yu had kept his distance from these red-umbrella-white-stemmed fungi, while still being curious about their taste.

Professor Sprout personally cultivated non-toxic toadstools; surely she wouldn't trick the Little Wizards?

The Charms Class professor was a short man, Filius Professor Flitwick. Besides excitedly dropping his pile of books when calling Harry's name during roll call, he behaved like a knowledgeable professor.

Professor Flitwick, who had some goblin ancestry, was a highly skilled wizard and had won multiple dueling championships in his youth.

Chen Yu loved Professor Flitwick's class the most. Although he was the Head of Ravenclaw, he treated all students equally.

After Charms Class class, Chen Yu would always pester Professor Flitwick with difficult questions about spells.

This generous Charms Class master was not stingy with his knowledge, and each answer made Chen Yu feel like he had genuinely learned something.

The system's skill proficiency increase notifications wouldn't lie.

As for History of Magic, Chen Yu didn't particularly like it.

Professor Binns' lectures were simply too hypnotic.

Every time he felt like he couldn't remember many words, his vision would go black, and he'd wake up to find he had fallen asleep.

This reminded Chen Yu of Jigglypuff from 'Pokemon' he used to watch.

Every time Jigglypuff sang, it would knock out a group of humans and Pokemon who heard its song.

It was truly terrifying.

Fortunately, Professor Binns would float away immediately after class, unlike Jigglypuff, who would take out its marker and draw all over the sleeping subjects.

It was truly a blessing in disguise.

As for Potion Class class, it was a disaster for Harry.

Potion Class class began with Snape ignoring Hermione's raised hand to ask Harry a series of Potion Class questions, followed by a string of sarcastic remarks.

This made Harry feel targeted by Snape.

Harry was absolutely right; he was being targeted by Snape.

Snape truly had a love-hate relationship with Harry.

He and Harry's mother grew up together before she met James; they were childhood sweethearts, innocent and inseparable.

Lily was the 'white moonlight' in Snape's heart; he had loved Lily since childhood, wanting to spend his life with her until old age.

Childhood sweethearts, however, could not compete with a 'destined' arrival.

Unexpectedly, James appeared, charming Lily's heart with just a few words.

Snape was so angry his teeth were almost grinding to dust.

Especially Harry's face, which looked exactly like James's when he was a child.

If it weren't for Harry's eyes being like Lily's, Snape probably would have thrown him out of the classroom the moment he saw him.

Snape's targeting of Harry caused Gryffindor to lose many points.

The only annoying thing was that Snape's anger towards Harry seemed to be a bit of an area-of-effect attack.

With Harry as the center, and students within a one-meter radius as the target.

Whoever was close to Harry was likely to be affected.

During class, Neville's mistake caused the boiling potion to splatter all over the classroom, and he himself was soaked in scalding hot water, screaming in pain.

Snape immediately deducted points from Harry and Ron, because their group was closest to Neville and they hadn't warned him when Neville added the porcupine quills.

Hermione tried to argue with Snape, but Snape also deducted a point from her for contradicting a professor.

The first Potion Class class ended with Snape's targeting of Harry.

Chen Yu initially thought he would despise Snape's Potion Class class, but he unexpectedly found himself completely overwhelmed in Defense Against the Dark Arts Class.

The class Chen Yu hated the most now was Defense Against the Dark Arts Class.

It wasn't that Professor Quirrell targeted him during class, but rather that Professor Quirrell inadvertently targeted all the Little Wizards attending the class.

Before class, Professor Quirrell would cover himself in garlic juice, making the entire classroom reek of a heavy garlic smell.

A faint garlic smell, Chen Yu could tolerate.

But this strong, foul garlic smell, Chen Yu simply couldn't stand.

He quickly turned his sense of smell down to its lowest setting, and while this prevented him from smelling Professor Quirrell's garlic odor, the irritation to his nose and eyes from the garlic was still unavoidable.

Chen Yu constantly felt his nose itching, his eyes unable to open, and he couldn't help but sneeze.

Not just Chen Yu, but other Little Wizards too; sneezes would occasionally erupt throughout the classroom.

It was impossible to concentrate on what Professor Quirrell was teaching.

Chen Yu now especially wanted to learn the Bubblehead Charm, as only then could he completely isolate himself from the multiple harms caused by the strong garlic smell.

Just thinking about having to take Defense Against the Dark Arts Class under Professor Quirrell for the entire semester filled Chen Yu with an indescribable sadness.

It was truly too difficult for these Little Wizards who came to Hogwarts to study.

Everyone said Professor Quirrell covered himself in garlic to ward off the vampires he encountered in Romania.

Each story was made up so convincingly, as if it were true.

Chen Yu, of course, knew the real reason Professor Quirrell covered himself in garlic juice.

Firstly, to mask his own unusual scent, preventing others from noticing anything strange about him.

Secondly, to prevent mischievous Little Wizards from getting close to him and pulling off the scarf on his head, revealing the other face on the back of his skull.

Before learning enough spells, Chen Yu didn't want to stick his neck out and expose Professor Quirrell's disguise in front of the entire school, creating a huge scene.

If Lord Voldemort became enraged and dragged him down, he would suffer greatly.

As for Astronomy class at night, there wasn't much to say. The entire class was spent observing the positions of the stars in the sky with a telescope.

Chen Yu had been very busy these past few days. During the day, besides attending classes on time, he would self-study spells in his spare time.

Sometimes, to complete a task, he would find an empty classroom to practice spells.

Hogwarts had many empty classrooms Idle for various reasons, making it easy to find an uninhabited classroom to cast spells and raise skill proficiency.

However, when practicing spells in an empty classroom, one had to be careful if anyone was passing by, and powerful spells could not be practiced, which was quite troublesome.

At night, after his roommates fell asleep, Chen Yu would quietly go out for a night stroll using the Serpent Spell.

Harry, who hadn't yet received his invisibility cloak, was still a good boy who went to bed on time every night.

Chen Yu hadn't had a chance to visit the Forbidden Forest yet; these past few nights he had been familiarizing himself with the layout of Hogwarts.

Hogwarts was simply too vast.

In these few days, Chen Yu had only explored about seventy to eighty percent of the visible routes within the castle.

With a hint from Dora the House-elf, he found the Hogwarts kitchens and learned the names of over a dozen other House-elves working there.

After teaching the House-elves a few Eastern dishes, he subtly mentioned his annoyance at often being disturbed while practicing spells.

Unexpectedly, he overheard information about the Room of Requirement from them.

Online rumors suggested that the mysterious builder of the Room of Requirement might have been Rowena Ravenclaw, the founder of Ravenclaw.

The House-elves, who had lived in Hogwarts for a long time, naturally knew about the Room of Requirement.

However, bound by rules, they couldn't directly tell the Little Wizards about its existence.

Therefore, the House-elves in the kitchen didn't directly tell Chen Yu that the Room of Requirement was on the eighth floor.

They only said that there was a strange room on the eighth floor of Hogwarts Castle that could provide Chen Yu with an undisturbed place to practice spells, and thoughtfully drew him a map to help him find it.

Since it was on the eighth floor, it must be the Room of Requirement.

Chen Yu had explored the eighth floor before but hadn't found any clues about the Room of Requirement.

The main obstacle was the moving staircases.

These magical staircases loved to move around, and although they had a certain pattern, they could easily make Chen Yu go to the wrong floor, making him unsure which floor he was on.

Now that he had obtained the exact location from the House-elves, he naturally wouldn't miss out on the Room of Requirement, this magical room perfect for practicing spells.

He pulled out the simple map drawn by the House-elves from his backpack and arrived at a wide corridor lined with many portraits.

At the end of the corridor, Chen Yu saw a portrait of a wizard being chased and beaten by a Troll with a large club.

Finding this painting, Chen Yu realized that he had been here two days ago.

However, at that time, the painting depicted a wizard teaching a Troll to dance, not a scene of a wizard being beaten.

If he remembered correctly, opposite this portrait should be the entrance to the Room of Requirement.

"I need a place to practice spells undisturbed!"

"I need a place to practice spells undisturbed!"

"I need a place to practice spells undisturbed!"

Chen Yu kept repeating this thought in his mind, then walked past the blank wall three times in a row.

By the third time he passed the blank wall, a door with black stripes appeared on the empty wall.

Chen Yu pushed open the door with an excited heart, and after he entered, the door automatically closed behind him.

This was a very spacious room, about half the size of a football field, with two rows of practice dummies on either side.

Chen Yu carefully checked the room for portraits.

Hogwarts was full of ubiquitous portraits, all Dumbledore's informants. To practice Unforgivable Curses behind Dumbledore's back, one needed to practice in a place where the portraits couldn't see.

Confirming there were no portraits, he breathed a sigh of relief.

He had always been well-behaved at Hogwarts, so Dumbledore shouldn't have noticed anything unusual.

Chen Yu pulled out his wand from his backpack and tried out the Avada Kedavra on a dummy.

A flash of green light, and the dummy hit immediately shattered into pieces.

These were traces left by the impact of magic.

If a human or animal is hit by Avada Kedavra, the victim usually dies instantly, leaving no marks on their body.

【Player used Avada Kedavra, skill proficiency +1】

After casting the Killing Curse, Chen Yu waited for a moment.

He didn't see Dumbledore suddenly appear beside him.

He couldn't help but feel relieved, and then began to practice with peace of mind.
