For a wizard, magic is power.

Chen Yu knew that the House of Malfoy was a very wealthy pure-blood wizard family, and pure-blood families like them usually had a habit of collecting books.

The monopoly of knowledge, no matter in which period, is one of the important means for the upper class to consolidate their rule.

Chen Yu originally didn't have too much hope for Draco, only thinking that it would be best if Draco found the spell books he wanted from his own family, and it didn't matter if he couldn't find them.

Even if Draco didn't find a single one, Chen Yu didn't plan to publicize Draco's scandal from yesterday.

He hadn't fallen to the point of truly being serious with a child.

Making Draco suffer social death would be much more severe than just beating him up.

Even if Draco was an arrogant and unruly fop spoiled by his family.

A beating would solve most of the problems.

In his imagination, it would be good if Draco could produce one or two spell books containing the spells he wanted.

He didn't expect Draco to actually give him a surprise.

Draco's efficiency was quite fast.

Chen Yu didn't know what Draco told his family; he probably didn't mention being bullied. It was only three days later that he received a package from Malfoy.

Draco's owl flew in front of Chen Yu, carrying a package containing several spell notebooks and books, and one of the books also had a note from Draco tucked inside.

"Chen Yu, I've basically found all the spell books and related notes you wanted."

"These books and notes are temporarily borrowed by you, and I hope you can take good care of them."

"I couldn't find any books or notes related to Occlumency. My father said that they, along with some other magic books, were donated to the Hogwarts Library eleven years ago."

"Those donated books were all enchanted with a Confundo, so most people can't find them."

"But don't worry, my father gave me a card, and he said the card would glow when it gets close to those books."

"I hope you keep your promise; no sixth person will know about what happened that day!"

Chen Yu opened the package cloth, and inside were two books and four notebooks.

The books were "Ancient spell Explanations" and "Dark Arts Theory and Research."

Of the four notebooks, one was inscribed with the name Abraxas Malfoy, and the remaining three with Lucius Malfoy's name.

It seemed they were notes left by Draco's father and grandfather while studying spells.

Upon seeing the notebooks sent by Draco, Chen Yu could roughly guess what had happened.

Draco must have told his father that he himself wanted to learn those spells.

Otherwise, who would give such private notes to an outsider?

Truly, a grandson selling his grandfather's land without a pang of conscience.

Chen Yu smiled faintly, looking at the somewhat aged notebooks, thinking that Lucius truly spared no effort in cultivating his son.

He put the books into his backpack, found a deserted place, took out the Serpent Spell, put himself in an invisible state, and under the cover of night, arrived at the Library.

He used Alohomora to open the Library's main door and walked directly towards the Restricted Section.

Chen Yu's gaze swept over rows of bookshelves.

Before, Chen Yu had secretly come to the Restricted Section at night.

He had secretly flipped through forbidden books such as "Lost Ancient Magic," "Protected Brains," and "Broken Minds."

The books did not contain Occlumency, but rather other strange, even terrifying, knowledge.

Forbidden books are forbidden not only because their contents are taboo, but also because the books themselves are very dangerous for Little Wizards.

Chen Yu saw the card in his hand glow faintly as he stopped at a certain book, his gaze fixed on a magic book titled "Understanding Your Brain and Magic."

This magic book should be one of the magic books donated by the House of Malfoy eleven years ago.

He just didn't know if Occlumency was recorded inside.

As soon as he opened the book, the pages turned without wind.

The entire book seemed to have a consciousness of its own, with pages automatically flipping.

At the same time, a mist began to spread on the pages, and the surrounding scenery gradually blurred.

Chen Yu watched expressionlessly as a Dark Wizard, wearing a black robe with his face hidden in the hood, performed a craniotomy on him.

Seeing this bizarre scene, Chen Yu was already accustomed to it.

After continuing to watch the complete craniotomy expressionlessly from the perspective of the first victim.

His perspective shifted, and before his eyes appeared a thin man, whose body was tied to a chair, with his limbs and neck fixed, unable to move.

He was wearing a wizard's robe, and in his hands were two sharp scalpels.

This time, the perspective shifted from the victim to the perpetrator.

Chen Yu felt his body move automatically; the scalpel precisely cut open the victim's scalp, and with a light flick of the blade in his hand, the victim's skull disappeared.

Truly, 'lifting your skull cap'.

Then "Chen Yu" began to speak.

His voice was hoarse, as if a lump of phlegm was stuck in his throat.

"Since Avis made a mistake, let him atone for it by being the Teaching Materials for this lesson."

"All of you, pay close attention. I will only explain the knowledge once. I hope the Teaching Materials for the next lesson won't be you."

"Everyone, carefully observe the brain distribution of this wizard apprentice."

"This is the brain, the most important part of the central nervous system."

"This is the left brain, this is the right brain, both connected by the corpus callosum, which is made of nerve fibers."

"I told you before that wizards control magic with emotions, and the nerves that control emotions are in the front part of the brain..."

Chen Yu listened to himself rambling about the structure of the brain for a while.

Then he watched a Dark Wizard perform a craniotomy on him, pointing at his exposed brain and explaining it to someone unknown.

If he hadn't set the system's pain level to 0, he would probably be empathizing with the victim by now.

The forbidden books in the Restricted Section are truly not something ordinary people can endure.

Most of the forbidden books placed in the Restricted Section like to play tricks.

He remembered once, when he accidentally knocked over a book in the Restricted Section, upon opening it, a face would appear and scream loudly.

The time before last, when he opened "Broken Minds," he browsed the bizarre world imagined in the mind of a wizard suspected of being mentally ill.

He wondered what kind of mindset the authors of these books had.

They just liked to create these terrifying and horrifying things to make readers feel empathy.

No wonder they were placed in the Restricted Section, forbidden for Little Wizards to browse.

If Little Wizards read these, it would be strange if their personalities weren't twisted.

After Chen Yu watched a complete explanation of the brain and magic, the surrounding illusions disappeared.

The book in his hand had also turned to the last page.

Even without pain, the contents of the book still made him break out in a cold sweat.

It was like watching a 3D horror movie; perhaps only medical students would be accustomed to such scenes.

Chen Yu put the book back on the shelf and wiped the sweat from his forehead.

He squatted down and found the card glowing again; it was another book donated by the House of Malfoy.

The book's title was "Beware – The Peering Brain."

Upon opening the book, Chen Yu felt a mysterious force surge out from within, rushing towards his mind.

Instantly, he felt as if a pair of eyes were darting around his mental world.

He slammed the book shut.

Only then did the strange sensation in his mind gradually disappear.

"Haha, The Peering Brain, truly living up to its name."

Chen Yu put the book back in its original place.

No wonder Draco gave it so readily; it turned out these books all had some kind of trap.

This was also Draco's revenge against him.

Ordinary Little Wizards, both physically and mentally, simply couldn't withstand the forbidden knowledge in the books.

He remembered someone saying that the book Lord Voldemort used to create horcruxes was found in the Restricted Section.

Chen Yu even suspected that when Lord Voldemort was young, he wasn't so crazy; perhaps he read too many forbidden books in the Hogwarts Library, was tempted by the forbidden knowledge of immortality recorded in a certain book, and only then tore his soul to create horcruxes, gradually becoming so insane.

Continuously reading these forbidden books, even if the body could endure it, the spirit would still feel somewhat uncomfortable.

Every time he opened one of the forbidden books just now, they absorbed a part of his mental energy.

After resting for a good while, he continued to search for books containing Occlumency in the Restricted Section with the card Draco had given him.

He stopped again at a row of bookshelves, seeing the card in his hand glow faintly once more.

Chen Yu glanced at the title of the book closest to the card: "Reversed Thought and Logic."

When he took this book from the shelf, its title changed.

"Legilimency - Brain Peeking and Counter Curse."

Hey, he found it.
