Hogwarts is quiet at night, with a sense of déjà vu of an eerie castle in a horror movie.

However, it only seems that there is no one.

All the rules of Hogwarts are useless in many cases, as long as the ability is enough to do something unusual without being discovered or caught, then all the rules are a dead letter and useless.

This is especially true of curfews and forest bans.

Although Dumbledore would repeat this every year at the opening dinner, it was a pity that almost all of the older students violated these two rules.

Ike could clearly feel that at the door of an abandoned classroom next to the corner of the stairs on the fifth floor, there were two students next to each other who didn't know what they were doing.

They weren't very skilled in the illusion charm, and when Ike casually glanced downstairs, he noticed strange fluctuations in mana.

"It doesn't even seem to be at the level of Lv1."

Ignoring the pair, who don't know if it's a rotten country specialty or a guy who attracts opposites, Ike cautiously came to the library.

At night, the library door was closed, but not locked, and it was pushed open with a slight push.

Closed the door with his backhand and went straight to the entrance of the forbidden book area. Although it is locked, it is no different from not locking, and it is opened with a lock picking spell.

"If you don't get caught, you won't do anything."

Ike secretly complained, and had a deeper understanding of the rules of Hogwarts.

Unlike the books outside the door for students to flip through at will, as soon as he stepped through the door of the forbidden book area, Ike faintly felt a chill.

"Content that is not suitable for young students" is a description that sums up all the books in the forbidden area.

But pay attention to the point: unsuitable, young.

Some of the content is really dangerous, such as books related to black magic, most of those books are used with vicious and ruthless magic, and even if people who don't know why pick it up, they may be hurt in the form of bites, curses, soul shocks, etc., and the content is mostly similar to forbidden blood fusion, vicious curses, evil magical creature cultivation and sacrifice rituals, etc.

These are obviously not suitable for young wizards with low magic levels and magic perceptions.

On the other hand, if a wizard has a high level of magic, magic cognition, and magic control, there is no big problem in looking at it.

Ike scrutinized the forbidden books on the shelves, ignoring the blood-colored, unknown leather covers and almost inaudible whispers that he didn't dare touch right now.

Others, who were chained and still struggling, walked away in circles.

After searching for a while, Ike found what he was looking for on a bookshelf that looked the most ordinary.

Miranda Goshak's Book of Spells and the complete, uncut version of Standard Spells.

The Book of Spells, the first spell textbook written by Miranda Goshawk, was translated into 72 languages, including elves and merfolks, and used by all magic schools around the world.

However, because it contains some evil spells, it has caused a lot of controversy. Although Miranda Goshawk argues that the use of moderately aggressive spells prevents students from using more dangerous spells to resolve disputes, this clearly does not satisfy doubters and opponents. So I don't know when the Book of Spells was placed in the forbidden book area.

Unfortunately, locking up the Book of Spells doesn't stop the curse from circulating among young wizards.

"Standard Spells" is a specially written textbook for young wizard charms after the "Book of Spells" was boycotted, based on her experience at Hogwarts. Compared to the Book of Spells, Standard Spells has more spells and more detailed explanations.

However, the first version of Standard Spells still had a lot of mischievous spells that could even cause serious damage, which caused Standard Spells to follow in the footsteps of the Book of Spells.

As for the subsequent series of textbooks, they are the product of the deletion of evil spells and offensive spells, and some difficult spells have also been removed.

For example, the Patronus Charm.

And both in the Book of Spells and in the complete and uncut version of the Standard Spells, there is a Patronus charm.

Putting the two books in his robes and locking the door to the forbidden area, Ike quietly walked towards the Ravenclaw Tower.

Hogwarts at night is almost as lively as it is during the day, and the troublemakers like to give the castle janitor some trouble. Peeves are fond of adding jobs to Filch and Lady Loris, and the Weasley twins, such as Gryffindor, are the best of them.

Ike didn't want to bet on whether the Christmas dinner would make the troublemakers give up their battle plans tonight, or maybe it was a subconscious weakness after doing something bad, and he would have to go back much faster.

After observing the door of Ravenclaw for a while, and making sure that there was nothing abnormal, Ike knocked on the knocker lightly.

"Where does the afternoon come before the morning?"

"In the dictionary."

"Very good answer."

The bronze knocker muffled and opened the door panel, revealing an archway leading to the common room. Ike maintained his illusion charm and walked straight through the common room back to the dormitory.

Put the loot under your pillow and go straight to bed.

When I woke up the next morning, it was almost noon. Stuart and Terry don't know where to play again, but Ike doesn't explore, and after a brief wash, he arrives at the portrait of the troll stick beating the stupid Barnabas with two books in his arms.

Walking back and forth three times, contemplating a room dedicated to Ravenclaw Ike Stred, an ornate door appeared on the wall as Ike had expected.

Pushing the door in, there is a room that resembles the Ravenclaw common room. It was spacious, and directly opposite the door was a fireplace with a row of letters glowing in soft white light, spelling out Ike's name. To the left of the fireplace is a single sofa with a Ravenclaw blue carpet on the floor, and a wooden coffee table above the embroidered eagle in the center of the carpet.

Behind the couch was a potions workbench with potions tools such as cauldrons, chopping boards, knives, grinders, spoons, etc., and a cabinet next to it, but there were no potions materials in it. On the other side of the wall is a desk, similar to the one in Ike's dormitory, flanked by two rows of bookshelves, which contain hundreds of books unique to the Room of Need, in addition to the books Ike owns and spends, such as "Self-Defense Spells", "Outwitting the Dark Arts", and "Common Spells and Spells", among others.

Sitting on the couch and placing the Standard Spell on the coffee table, Ike opened the Book of Spells. Most of the spells in it Ike have reached Lv6, and I roughly looked at the rest of the spells, such as the Bat Spirit Spell, the Incisor Race Stick, the Dancing Spell and other prank spells are not complicated, and some Ike has studied them, but they haven't used them, so there is no level display on the waste notepad system.

After flipping through it, there was only one spell left, which happened to be the target of Ike sneaking into the forbidden book area:

One of the oldest and most powerful defensive spells - the Patronus Charm!
