"I want to go back."

Elena lowered her eyes, avoiding Dumbledore's gaze, and whispered at the end of Dumbledore's long silver beard.

If Elena wants to choose the person she least wants to meet in the magic world, there is no doubt that she must be the famous principal of the Hogwarts Magic School, Albus Dumbledore.

Not only because of his outstanding magical power, but more importantly, Dumbledore is a master who is proficient in the study of God-taking and pursuing thoughts - in other words, he is a mind-reader similar to Professor Charles in "The X-Men".

Unlike other wizards who need to rely on spells and wands, masters such as Voldemort and Dumbledore who are proficient in the calculating of God do not need to chant spells when performing the calculating of God do not need to read spells, and can easily read thoughts with just the contact of sight. Therefore, when someone lies to him, they can always accurately judge them.

Judging from the original work, there is no legal restriction on using the God-Suiting Thoughts, because when Snape was teaching Harry, Dumbledore used the God-Suiting Thoughts without hesitation when asking others about emergency situations. Obviously, Elena did not think that Dumbledore would be so skillful and not peeping at her brain.

You know, as a time traveler, Elena has too many secrets to be known. From the moment she woke up in the common room in Gryffindor, Elena has been thinking about how to get through this level.

"You seem to be afraid of me?"

Dumbledore's eyes flashed over the girl's slightly trembling shoulders, shrugged helplessly, and said gently. "Am I so ugly? You know, I always thought I was quite popular with children."

He became more and more curious about the silver-haired girl in front of him. Whether it was the magical piano piece that seemed to have magic power before, or her understanding of the entire magic world, it seemed so unique.

"It's not because I'm afraid, I just simply hate the rude and rude way to take the God and take the thoughts."

Elena took a deep breath, tried to calm herself down, raised her head, and looked at Dumbledore's eyes fearlessly and said, "Since you have already reached this point, it is obviously meaningless to escape blindly, and it is better to try to confront her head."

"I don't think there is anything to keep talking to a robber who breaks into someone else's brain."

Generally speaking, in the cognition of wizards, there are only two ways to resist the surrender of God and take thoughts.

The first method is to try to avoid eye contact, distance yourself from the caster, and reduce the success rate of the mind-catching and thinking.

However, Elena believes that this method may not be so effective for a master of divine enchanting and chanting like Dumbledore.

Another is to learn brain closure, like Professor Severus Snape, to close the brain to fight magic invasion and influence, and even allow the brain to lie without self-exposed.

It is equivalent to a directional defense spell for the god-taking thoughts, but this is also unrealistic for Elena.

However, in fact, in Elena's opinion, wanting to hide her thoughts does not mean that she must drive the other party out of her brain. In fact, there is a third way of confrontation.

That is, use rigorous scientific knowledge to fight against mysterious magical powers.

Elena tried hard to empty her mind and began to recall a complex manifold analytical mapping she learned in college: Li Qun E8 (【Lie group E8】), a world-class mathematician who worked with their unremitting efforts, took four years to complete one of the most complex mathematical structures in the world.

This is also the only way she thought of during her Hogwarts tour this day, and she could resist Dumbledore's ability to capture God's thoughts - so that their thoughts can be explored but not understood.

Li Qun was invented by Norwegian mathematician Sophus Lie in the 19th century when studying multidimensional symmetry. After E8 was proposed in 1887, not many people have understood its structure until now.

It is used to explain the phenomenon that symmetric objects can move at will without changing shape. E8 explains the symmetry of 57-dimensional objects, one of which is known to only advanced mathematicians - E8 itself has 248 dimensions.

The reason why Li Qun E8 was chosen is because many scientific projects need to process a large amount of data, but the calculation of E8 is an exception: the amount of data required to be input is very small, but the answers obtained are huge and very intensive.

In other words, Elena only needs to recall the basic mathematical derivative formula in her mind. If Dumbledore wants to try to interpret it, she needs to complete the entire derivation based on the formula.

To give a simple example, it is like when Einstein was explaining the theory of relativity, everyone could understand his language, but could not understand the meaning of his language.

However, Elena went further on this basis and laid a small hole, that is, as long as she tried to start deducing and understanding [Li Qun E8], she would inevitably fall into the terrible workload of human genetic engineering dozens of times. If the data generated by the entire calculation process were listed on paper, the required paper area could cover the entire Manhattan.

You should know that human genetic engineering requires 1 billion bytes of disk storage space, while E8 requires 60 billion bytes.

Even if the four founders of Hogwarts were resurrected, it would not be possible to directly complete the understanding process under the foundation of zero-foundation advanced mathematics.

"Is this the power of a non-magical world?"

The old man's blue eyes behind the half-moon lenses quietly looked at Elena for a second or two, then took the initiative to move away from his gaze, rubbed his eyebrows slightly tiredly, and let out a deep sigh of emotion.

The spiritual world of the mixed-race veva is originally more sensitive than that of ordinary little wizards. Coupled with the rigorous and orderly mathematical model that exists like exquisite art, Dumbledore just tried to interpret it for a second or two before feeling his brain began to hurt.

More importantly, after this simple glance, Dumbledore finally intuitively realized that what Elena said before, the terrifying growth power of the non-magical world now - the study and exploration of the origin of the world, no longer belongs to the field of wizards.

Dumbledore calmed down, calmed down, and solemnly looked at Elena standing next to the piano again.

The little silver-haired luoli's tender face looked particularly nervous, and her blue wet eyes were full of hostility, and her petite body shook slightly unconsciously. It was obvious that she was in a strange environment, and she was not as strong as she was in a speech.

How afraid is this child... about the magic world?

Dumbledore shook his head, and as Elena looked at him as if she was facing a great enemy, he slowly walked to the girl, squatted down and let the two of them have their eyes in parallel. He carefully stretched out his hand, touched the girl's silver-shiny hair, and said sincerely.

"I'm sorry, please forgive the confusion of an elderly old guy."

Dumbledore's eyes were soft and sincere, and there was no sharp look like before. He looked like he accidentally angered his granddaughter and the helpless old man, full of guilt and pity.

"I promise you as Principal Hogwarts that I will never use God-Survey to seek thoughts on you again."

“…”

Elena bit her lip, her expression slightly calmed down and she didn't say anything.

It is difficult for anyone to feel disgusted with this great wizard who has run through the entire Harry Potter movie. Since Dumbledore made a promise in the name of Hogwarts, he will naturally not break his promise again.

Seeing that the girl's eyes were slightly loose, Dumbledore smiled slightly, took out his magic wand and shook it gently, and brought a cup of ice cream balls that emitted cold air like magic.

"As an apology, would you like to try this lemon ice cream made in Hogwarts' kitchen? As far as I know, it should be a very popular dessert in your world. I like it very much."

Dumbledore blinked flexibly at the silver-haired little luoli and handed the tableware forward.

"Hmph, I'm not a three-year-old!"

Elena looked at Dumbledore as if she was coaxing a child. She glanced at the delicious ice cream balls, bulged her cheeks with some anger, and couldn't help but say.

So after casually peeking at the girl's thoughts, I tried to coax her with a little dessert. How could it be possible?

Notice the look of the silver-haired luoli, Dumbledore's smile became stronger again. He gently pulled Elena's hand, placed the porcelain cup containing lemon ice cream on it, and said gently.

"So, can you spend more time listening to an old man's nagging now?"

After hesitating for a few seconds, Elena stuck out her tongue and licked the cold lemon ice cream, feeling a cool and sweet taste blooming from the tip of her tongue.

"...Well. Tell me." The silver-haired little luoli squinted her eyes happily and said with a small spoon in her mouth.
