Harry Potter and the Old Ones

Just as Neville's grandmother was talking about the glorious deeds of her son and daughter-in-law, a pale, almost bloodless palm stretched out from the hospital bed behind Mrs. Longbottom, interrupting Mrs. Longbottom's tirade. .

"Oh, Alice, what's the matter?" Mrs. Longbottom asked softly.

Neville's mother came slowly in her nightgown.

She no longer has the round and happy face like Moody's in the photo of the earliest members of the Order of the Phoenix. Her face is now thin and haggard, her eyes are extremely large, her hair is white, messy and dry. She seems not to want to speak, or cannot. Said, but she timidly pointed at Nawi, holding something in her hand.

"Another one?" Mrs. Longbottom said a little tiredly, "Very well, Alice, very well... Neville, take it, whatever it is."

Neville had already extended his hand, and his mother tossed him a wrapper from Bubbles Super Bubble Gum.

"Very good, dear." Neville's grandmother patted her shoulder, pretending to be happy.

But Neville whispered: "Thanks, Mum."

His mother staggered back, humming a song.

Neville looked at everyone defiantly, as if prepared to be laughed at, but Harry thought he had never encountered anything less funny.

"Okay, we should go back." Mrs. Longbottom sighed and put on her long green gloves. "Nice to see you all. Okay, Neville, throw the candy wrapper into the trash can. She gave you enough to cover your bedroom, right?"

But as the grandfather and grandson left, Harry believed he saw Neville stuffing the candy wrapper into his pocket.

The door was closed gently.

"I never knew," Hermione said through tears.

"I don't know either." Ron's voice was hoarse. "If I knew, I would never ask that question."

"After Christmas is over..." Harry said silently, "After Christmas is over... I want to ask Tiera... to see if there is any way he can cure Neville's parents."

"Yes." Hermione agreed, "Tiera is so smart, he must have a way to cure Neville's parents."

Now in the hearts of Harry and Hermione, Tiera is almost omnipotent——

After all, what can a talented little wizard who can even avoid death do not do?

The days outside Hogwarts always go by extremely fast. Although Harry, Ron and Hermione were reluctant, they still had to pack their bags and return to Hogwarts on January 8th. Gewoz.

Life after returning to Hogwarts was not so easy——

First there was Tiera, who disappeared again.

After returning from No. 12 Grimmauld Place, Harry originally thought that he could immediately start the next phase of training for Dumbledore's Army, but he was immediately poured cold water on it by Tiera -

"Finished?" Harry screamed in surprise, "What do you mean finished?"

"I have basically finished teaching the knowledge points that I can hand in." Tiera said calmly——

This is a fact. The three-dimensional theory of magic itself does not have much knowledge. Tiera broke it up and crushed it, drew inferences from one case and mixed it with some of her own personal information, and barely managed to complete one semester.

For the rest, if they want to continue to improve, they need to improve themselves and improve their mathematical skills.

Tiera was six years old when she first traveled through time. Until she entered school at the age of eleven, in addition to three-dimensional magic theory and some necessary knowledge, Tiera had been retrieving the high-level mathematics she learned during the postgraduate entrance examination.

So even though he has been making troubles, planning troubles, and making big things since he entered school, he has not neglected his studies. Under the dual study of new mathematical magic and old-fashioned spell magic, his magical literacy has been improving rapidly. promote.

To put it bluntly, the crux of the problem for Hogwarts students now lies in their underlying mathematical calculation abilities.

As the saying goes, the economic base determines the superstructure.

The financial foundation of the students at Hogwarts is not good, so it is no wonder that the superstructures are all crooked.

"The rest is that you need to practice on your own." Tiera said, "In addition to practical exercises, you also need to improve your math skills - Oh, by the way, Hermione."

"Huh?" Hermione asked.

"If it's convenient, you can ask your parents to buy you some mathematics exercises from the Muggle world, mainly math problems in algebra, solid geometry, plane analytic geometry, introduction to modeling, etc., and help everyone do it."

"Okay." Hermione replied firmly.

"Wait a minute, Tiera!" Harry suddenly shouted at this time, "Well... that's it... Tiera... I think... I think practicing Muggle mathematics... is this really necessary? ?Although the method you taught us to use mathematics instead of ancient runes and Latin to construct magic spells is indeed very convenient, but in this case we really need to give up the method we have always been familiar with and replace it with another unfamiliar one. Method?"

"I mean that for us at this stage... practicing ancient runes and Latin spells can enhance our strength." Hermione quickly added, "I mean I decided that I would use ancient runes and Latin spells to enhance our strength." English or Latin incantations are smoother than mathematical model incantations..."

"No, Harry." Tiera said with a smile, "Continuing to use and learn ancient rune and Latin spells will not increase our strength. To be precise, continuing to learn spells in this way will only make us Our learning efficiency is the same as when we are in class. If you learn ancient runes and Latin spells in my class, it is simply making up for your missing Defense Against the Dark Arts class. This will not make you stronger. It will only make the talented among you more talented and the mediocre even more mediocre.”

"You are a talented wizard." Tiera said, "So you can easily learn some magic that is difficult for others to learn, but you alone are not enough."

"Our goal is to improve the strength of all Dumbledore's Army." Tiera said, "Not you, no, not just you, but everyone."

"But your question reminded me." Tiera said, "I don't seem to have made it clear the importance of using pure mathematical methods to construct magic configurations."

"Whether it is ancient runes, Latin or mathematical methods, they are essentially descriptive magic." Tiera explained, "That is to say, whether we use ancient runes, Latin, or even English or Japanese , Chinese, oracle bone inscriptions, or mathematical formulas are all descriptions of a certain rule in the universe, a certain type of phenomenon, or even a certain god. This description, combined with the power of the spiritual dimension, constitutes magic."

"The descriptions in English and Japanese are not accurate enough, so Hogwarts studies ancient runes and Latin. However, compared with mathematical models, Latin and ancient runes are not accurate enough." Tiera paused. , and continued, "To be precise, there is no language in the world that can compare with mathematics, and no language can describe these rules and phenomena more accurately and appropriately than mathematics."

"It is true that we can use Latin and ancient runes to describe a levitation, a clear spring like water, a match turned into an iron needle, and a mouse turned into a goblet, but-"

"Can we use them to describe the sun? Can we use them to describe the moon?" Tiera asked fiercely, "Can we use them to describe the fall of stars? Can we use them to describe the divided lake? We Can it be used to describe death and rebirth?”

"No, and cannot." Tiera said firmly, "When faced with this kind of power of nature, any language we are familiar with seems too poor and immature."

"There is only mathematics, only pure mathematics. When we study, or even face the rules and even the truth of the universe that are far beyond our imagination, the only tool we have is mathematics, and only mathematics."
