"I want to go back. ”

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

If you want Elena to choose the last person she wants to meet in the wizarding world. Undoubtedly, it must be the famous headmaster of Hogwarts School of Witchcraft and Wizardry, Albus Dumbledore.

Not only because of his superior magical prowess, but more importantly, Dumbledore was a master of regents - in other words, a mind reader similar to Professor Charles in X-Men.

Unlike other wizards, who rely on spells and wands, masters such as Lord Voldemort and Dumbledore who are proficient in Dementoring do not need to recite incantations when casting Dementoring, and can easily read thoughts with just eye contact. Therefore, when someone lies to him, they can always tell it accurately.

Judging from the original books, there are no legal restrictions on the use of Deception, as Snape did not hesitate to use Deception when teaching Harry, and Dumbledore did not hesitate to use Deception when questioning others in an emergency, and it is clear that Elena did not think that Dumbledore would be so qualified not to peep into her brain.

You know, Elena, as a time-traveler, has too many secrets that can't be known. From the moment she woke up from the Gryffindor common room, Elena had been thinking about how to get through it.

"You seem to be afraid of me?"

Dumbledore's gaze swept over the girl's slightly trembling shoulders, and he shrugged helplessly, and said gently. "Am I that ugly? You know, I always thought I was very popular with children. ”

He became more and more curious about the silver-haired girl in front of him, whether it was the wonderful piano music that seemed to have magic before, or her knowledge of the entire wizarding world, it seemed so different.

"It's not that I'm afraid, it's just that I just hate the rude detriment. ”

Elena took a deep breath, tried to calm herself, raised her head, and her blue eyes looked directly into Dumbledore's eyes without fear and said, since it has come to this point, it is obviously pointless to blindly escape, it is better to try to confront it head-on.

"I don't think there's any need to keep talking to a robber who has broken into someone's brain. ”

Generally speaking, there are only two ways to resist the deception of the deceitful in the minds of wizards.

The first method is to avoid eye contact as much as possible, and distance yourself from the caster, reducing the success rate of the regent's retribution.

However, Elena thinks that this method may not be so effective for a powerful master of Deception like Dumbledore.

The other is to learn Occlumency, as Professor Severus Snape did, to close the brain to resist the invasion and influence of magic, and even to allow the brain to lie without exposing itself.

It's the equivalent of a targeted defense spell against the Guardian Mind, but that's just as unrealistic for Elena.

However, in fact, in Elena's view, if you want to hide your thoughts, it doesn't mean that you have to drive the other party out of your brain, in fact, there is a third way to fight.

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

Elena tried to clear her mind and began to recall a complex manifold analytic mapping she had learned in college: Lie group E8, a team of 18 of the world's top mathematicians who worked tirelessly to complete one of the world's most complex mathematical structures over a period of four years.

It was the only way she could come up with a way to resist Dumbledore's receptivity during her day of Hogwarts - to make the mind searchable but not understood.

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

It is used to explain the phenomenon that symmetrical objects can move at will while maintaining their shape. E8 explains the symmetry of objects in 57 dimensions, and one of the reasons is known only to advanced mathematicians – E8 itself has 248 dimensions.

Li Qun E8 was chosen because many scientific projects need to process large amounts of data, but the calculation of E8 is an exception: the amount of data required to be entered is small, but the answers themselves are large and very intensive.

In other words, Elena only had to recall the basic mathematically derived formulas in her head, and if Dumbledore wanted to try to decipher them, he would need to complete the entire derivation based on the formulas.

To give a simple example, when Albert Einstein was explaining the theory of relativity, everyone could understand his language, but they could not understand the meaning expressed in his language.

It's just that Elena has gone one step further on this basis and buried a small hole, that is, as long as you try to start deducing and understanding [Li Qun E8], then you will inevitably fall into a terrible workload of dozens of times the human genetic engineering, if you list the data generated by the entire calculation process on paper, the required paper area can cover the entire Manhattan.

You know, human genetic engineering requires gigabytes of disk storage, and E8 requires 60 billion bytes.

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

"Brilliant genius idea, is this the power of the non-magical world?"

The old man's blue eyes behind the half-moon lenses quietly looked at Elena for a second or two, and then he took the initiative to look away, rubbed his eyebrows slightly tiredly, and let out an exclamation full of emotion.

The half-breed girl's mental world was already more sensitive than that of ordinary young wizards, and coupled with the mathematical model that existed as a rigorous and orderly art form, Dumbledore only tried to decipher it for a second or two before he felt a dull pain in his brain.

More importantly, after this simple glance, Dumbledore finally intuitively realized that the terrifying growth force of the non-magical world that Elena said before, the research and exploration of the origin of the world, no longer belongs only to the realm of wizards.

Dumbledore took his heed, collected his thoughts, and solemnly re-looked at Elena standing next to the piano.

The silver-haired little Lori's immature little face looked particularly nervous, her fawn-like lake-blue slightly wet eyes were full of hostility, and her petite body shook slightly unconsciously, obviously in a strange environment, she was not as strong as she was in words.

This kid ...... How much fear is there about the wizarding world?

Dumbledore shook his head, and under Elena's gaze, he slowly walked up to the girl, crouched down so that the two of them were in a parallel position, cautiously stretched out his hand, touched the girl's silver luster hair, and said sincerely.

"I'm sorry, please forgive an old guy for being confused. ”

Dumbledore's gaze was soft and sincere, and he didn't have the same sharp eyes as before, and he looked like an old grandfather who had accidentally angered his little granddaughter and was at a loss, full of guilt and pity.

"I assure you, in my capacity as Headmaster of Hogwarts, that I will never use the Regent on you again. ”

“......”

Elena bit her lip, her expression slightly softened, and she didn't speak.

It's hard for anyone to feel bad about this great wizard who runs through the entire Harry Potter films. Since Dumbledore made a promise in the name of Hogwarts, it is natural that he will not break his promise again.

Seeing that the eyes of the girl in front of him were slightly relaxed, Dumbledore smiled slightly, took out his wand and shook it lightly, and summoned a cup of ice cream ball with cold air like a trick.

"As an apology, would you like to try this lemon ice cream made in the Hogwarts kitchen? As far as I know, it's probably a popular dessert in your world. I love it too. ”

Dumbledore blinked nimbly at the silver-haired little Lori and handed the cutlery in his hand forward.

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

Elena looked at Dumbledore as if she were coaxing a child, glanced at the ice cream ball that looked delicious, puffed out her cheeks a little angrily, and couldn't help but say.

After peeking at the girl's mind at random, trying to coax it with a little dessert, how is it possible?!

Noticing the eyes of the silver-haired little Lori, the smile in Dumbledore's eyes became a little thicker, and he gently took Elena's hand, put the porcelain cup with lemon ice cream on it, and said gently.

"So, can you take a little more time now and listen to an old man's chatter?"

After hesitating for a few seconds, Elena stretched out her little tongue and licked the chilling lemon ice cream, feeling a cool sweet and sour taste bloom from the tip of her tongue.

“...... Not. You say. The silver-haired little Lori squinted her eyes happily and said with a small spoon in her mouth.
