By the time he returned to the Hufflepuff common room, Jon Hart had three thick books in his hands.

"Jon, Professor Sprout just sent some specimens, would you like to take a look?" Hufflepuff second-year Ernie McMillan, who was leaning against the window, shouted when he saw him return.

"Thanks, Ernie...... I'll come back later!" Jon declined his invitation and went straight back to his dorm.

He wrapped the three books in a newspaper in turn...... Although Hufflepuff's dormitory is a single piece, it is not excluded that other students will enter his dormitory for some reason and discover the existence of these books.

After all, the covers of several books look hideous and conspicuous.

On the cover of the first book is the face of an ugly witch whose eyes are cold and hollow, like a dark tunnel, bottomless...... And the title of the book is "Close Your Brain".

It was the only book he could find about "Occlumency" after a few days of rummaging through the library.

"Occlumency" is a kind of magic that resists the infiltration of the outside spirit, which can seal the brain to resist the invasion and influence of the mind, and the signature spell is "Regent Mind...... It was one of the spells Jon felt he most desperately needed to learn.

Due to the existence of the "Regent Mind" spell, whether in front of the White Wizards led by Dumbledore or in front of the White Wizards led by Voldemort, their thoughts are as transparent as glass, and they can see through them at a glance and have nowhere to hide.

As a time-traveler who knows the historical events of the next six years, it is extremely necessary to protect his identity and secrets from being discovered...... Now that he is a small character, Dumbledore has not noticed him, but what about the future, what if he catches Dumbledore's attention?

So he needed to learn and master Occlumency, before Dumbledore noticed his presence.

Then he turned his attention to the second book.

On the cover of the second book, a twisted, flesh-and-blood skull is depicted...... The tongue on top was twisted together, the tears under the eyes turned blood, and the nose was completely turned open...... The title of the book underneath it is a little difficult to read because of its age.

To be honest, Jon wanted to vomit at this hideous scene, and he quickly wrapped the cover in newspaper.

The spells in this book are disgusting...... There are many torturous spells in it, and although they are not part of the dark arts, they are still put in the forbidden book section because they are extremely harmful to people......

Tongue twisting, ear turning, skinning, etc.;

For the most part, Jon didn't have the slightest interest in these spells, except for one:

"Eye Curse!"

According to the account in "Where the Fantastic Creatures Are Located": "It is likely that the basilisk's skin has the same armor properties as the dragon's skin, and can reflect spells that hit it, and only its eyes and mouth are the only weak points of defense." ”

So the Eye Spell was the only spell Jon could think of that could deal damage to the basilisk.

Moreover, the basilisk's eyes are its deadliest weapon, and if you can blind it with the eye curse in battle, it will undoubtedly make it a big loss of strength......

This spell was also the spell that Jon was preparing to practice primarily during this time.

As for the third book.

Its cover is equally disgusting: a witch has many pairs of arms on her head, and a person on it that appears to have been turned inside out......

Its name is written underneath the illustration: "Potion of Power".

Potions of Potion contains many dangerous, controversial, and mysterious potions, which is why Hogwarts Library keeps the book in a forbidden section.

Borrowing this book is purely a hobby, and as long as it is returned to the library before Halloween anyway, it shouldn't have much impact on the plot.

......

"Jon, are you going to Quidditch?" asked Zacharis-Smith at one point as he knocked on the door of his dorm room.

"No, thank you!" Jon, who was lying on the bed with a thick book in his hand, turned him back.

"Quidditch, the more you fight, the more skilled you will fly......" Zacharith muttered as he knocked on the door of a dormitory next door, "Ernie, let's go to Quidditch together!"

Jon spent the whole afternoon in his room reading the books borrowed from the forbidden section, and didn't even bother to eat lunch and dinner...... Anyway, there were a lot of cakes and cookies in the dormitory that had been brought from the kitchen for the past two days, and the Hufflepuff students wouldn't be hungry.

Occlumency is more complicated than he imagined, no wonder the savior Harry has been "training" for more than half a year, and he doesn't even know what year and month he will be able to get out of the mountain and achieve some small success.

The eye spell was a bit of a surprise to him, because it was one of the few spells that did not rely on emotions, and he would not encounter too much hindrance to his own learning...... It's just that the overall spell release is quite complicated, and it also requires a period of dedicated practice.

As for "Potions", he just looked at the content about Polyjuice Potion and Truth Elixir, and the process of preparing both potions was incredibly cumbersome, making Jon feel that he should first take Snape's Potions class or two, and familiarize himself with the preparation process, before thinking about it.

......

Before you know it, the whole day of Saturday has passed.

I glanced at my watch, and it was almost twelve o'clock in the evening.

"Time flies!" Jon muttered, as he prepared to go to bed.

Suddenly, by the window of the dormitory, a strange sound suddenly came from the window.

Jon frowned and walked over.

The sound came from inside the cage of the two South African red spiders.

The two spiders crackled and banged on the glass with their heads and feet, looking very agitated.

It's perfectly clear that they're scared...... Scared of something wandering around the castle.

"Spiders are terrified when they feel the presence of the basilisk, and they will try to run away, because the basilisk is their natural predator......" Jon has long remembered the description of the basilisk in "Fantastic Beasts and Where to Find Them".

"It seems that the door to the Chamber of Secrets has been opened by Ginny Weasley......" Jon thought to himself with a solemn face, "The real plot is about to begin."

It's only Saturday of the first week of school.

Find an old garment that is no longer worn, and cover the glass cages of the two South African red spiders...... Don't let the sounds they make disturb you.

Jon lay down in bed, closed his eyes and fell asleep.
