Save the Bachelor of Heaven

Xiang Nan found the Ravenclaw diadem in the Room of Requirement when he was in the first grade.

However, he was worried that there was a curse set by Voldemort on it, so he never dared to use it, lest he be sucked away by Voldemort like Ginny, or be cursed by a fatal curse like Dumbledore.

Now that he has read all the books in Hogwarts, he has a considerable understanding of dark magic, so he has seen that the Ravenclaw diadem was indeed cursed by Voldemort.

However, this curse is not fatal. On the contrary, it contains Voldemort's unparalleled knowledge of dark magic. As long as you wear it, you can learn the world's top dark magic and become a dark lord as powerful as Voldemort.

And it is precisely because of this that this diadem is extremely dangerous, even more terrifying than a fatal curse.

Because the reason why people are looking for Ravenclaw's diadem is to inherit Ravenclaw's wisdom and become a powerful wizard like her.

But when they put on Ravenclaw's diadem, they learn Voldemort's dark magic. But they didn't know that it was Voldemort's black magic, and thought it was the inheritance of Ravenclaw, so they would learn it without any defense.

And the deeper they learn, the more they will be affected by black magic.

Because black magic must be driven by negative emotions such as hatred, killing, and resentment, the more people use black magic, the more corrupted and evil they become.

Just like to successfully release the Cruciatus Curse, you must have infinite evil thoughts in your heart. The stronger the evil thoughts, the more you want the other person to suffer, and the more powerful the Cruciatus Curse you release.

When Harry Potter hated Bellatrix extremely (she killed Sirius at the time), he released the Cruciatus Curse to her, but she just fell down without feeling much pain.

It can be seen how strong the evil thoughts are needed to release the Cruciatus Curse.

When they are corrupted and degenerate, Voldemort will take the opportunity to absorb their lives, seize their souls, and make them his hosts, just like his first Horcrux diary.

This is also a back-up plan for his own resurrection.

...

Fortunately, Xiang Nan knew that this crown was Voldemort's Horcrux, and the magic contained in it was Voldemort's dark magic, so he would not be so easily deceived.

On the contrary, he wanted to get Voldemort's magic knowledge for free, and then destroy this Horcrux after getting it for free.

But before that, he had to learn the brain block first.

Because Voldemort is a master of Legilimency, he will read other people's thoughts to see if they are loyal to him and whether they are really corrupted.

Ravenclaw's crown is one of his Horcruxes and also has the ability of Legilimency.

It will check whether the wearer is really corrupted and whether he really opens his soul to it.

If so, it will teach him more dark magic, more dark, evil, and taboo knowledge, further corrupt him, and then take over his body.

If not, it will cast a curse and hurt the wearer.

Just like the curse he cast in Slytherin's locket. If someone like Umbridge wore it, the locket would not harm her at all, and she could wear it on her chest and fiddle with it.

But when the locket was worn by Harry, Ron and Hermione, it had a negative impact on them, making them negative, pessimistic, and infighting, and even almost strangled Harry.

So before wearing the crown of Ravenclaw and making a deal with the devil Voldemort, Xiang Nan needed to learn the brain block first.

…

The brain block is a magic that resists the infiltration of the outside world. It can close the brain to resist the invasion and influence of magic, which can just restrain Legilimency and prevent it from reading your thoughts.

A more advanced master of the brain block can even disguise his thoughts and let people read the wrong information.

Snape is a master of the brain block, so he can wander between the Order of the Phoenix and the Death Eaters and act as a double agent. In the end, if he hadn't taken the initiative to provide Harry with his memory, everyone would know who he was loyal to.

He deceived everyone.

To practice brain occlusion, you need to eliminate distracting thoughts, put aside your emotions, not think, not feel... This is too easy for Xiang Nan.

Because anyone who has successfully practiced internal skills can be free of distracting thoughts. As a top master, Xiang Nan can achieve the realm of immortals and Buddhas of "no one, no self, forgetting both things and self".

Therefore, practicing brain occlusion is really a simple thing for Xiang Nan.

He quickly got into the door and learned brain occlusion.

Then, he officially wore the crown of Ravenclaw.

...

"Extraordinary intelligence is the greatest wealth of mankind." A subtle voice sounded in the crown, "Warrior, I'm glad you found my crown, I will teach you all my knowledge."

"Thank you." Xiang Nan responded.

"What knowledge do you want to learn?" The subtle voice asked.

"Any knowledge." Xiang Nan responded.

"Okay, I'll teach you part of it first." A subtle voice.

Then it began to teach Xiang Nan magic knowledge, including spells, potions, transfiguration, alchemy, all-encompassing and very rich.

Xiang Nan thought that after reading the Hogwarts Library, the Room of Requirement and the Prince family's collection, he had few people in the wizarding world who could compare with him in terms of knowledge reserves.

But after listening to Voldemort's teachings, he still had to admire that Voldemort was indeed a scholar. Not only did he reach the pinnacle of black magic, which was unmatched by anyone, but he was also quite rich in other magical knowledge.

Xiang Nan was fully focused and absorbed the knowledge seriously.

The biggest feature of the Ravenclaw crown is that it can increase the wisdom of the wearer.

Specifically, after wearing it, the mind will become very clear and very active. Not only will the memory be amazing, but the learning ability, understanding ability, perception ability, analysis ability, and judgment ability will also be greatly improved.

It can be said that after wearing it, even the mentally retarded can become a genius.

Therefore, Xiang Nan quickly absorbed the knowledge taught by Voldemort.

And he also keenly realized that Voldemort had some hidden dangers when imparting knowledge.

Ninety-nine percent of the knowledge he taught was serious knowledge, and it would be fine even if it was taught in the Hogwarts classroom.

Only one percent was forbidden and dangerous black magic, and it was precisely this one percent of black magic that was the most powerful, the best effect, and the most attractive.

At that time, he coveted the power of black magic, and became more and more interested in it, and eventually became addicted to it, unable to extricate himself, and his human nature became evil, corrupt, and dark, and eventually became Voldemort's puppet.

It's like a book called "Xingxing Dafa" is sandwiched between a pile of internal skills secret books.

People started to be careless and thought it must be a secret skill. But after practicing it, it was really powerful and improved very quickly, so they naturally became addicted.

And once you practice it and become addicted, you will embark on a road of no return.
