I really didn't want to practice immortality at Hogwarts

There is a saying, "Not all top academics have the ability to be highly focused, but anyone with the ability to be highly focused can become a top academic."

Maybe it was the "student master time" bonus of the luck fruit plus the level fruit, or maybe Zhang Chun was used to entering meditation during the process of absorbing the true energy.In short, when there is no one to disturb him, Zhang Chun, who is sitting quietly in the library, can easily enter that state of high concentration and read the books one by one in a mesmerizing manner.

Zhang Chun adopts a network learning method. When reading through a book, if he encounters a difficult or obscure chapter, he will collect books on related subjects.Read through it first, then find the relevant chapters and study them carefully. After you understand the doubt, turn over and continue your initial study.

The benefits of this are undoubtedly obvious. For example, knowledge is interconnected and it is easy to clarify the original meaning and relationship between each other, thereby achieving the purpose of deep learning.Knowledge is like a network, fixed node by node, and then connected to form a network structure smoothly, thereby achieving the dual fixation of understanding and memory.

But of course there are also disadvantages, that is, it requires a lot of reading and repeated comparison time.

Fortunately, for Zhang Chun now, his reading speed is as fast as a Firebolt, so the amount of reading and time are not so obvious.

After entering a state of high concentration, Zhang Chun did not feel the passage of time at all. The different concepts, formulas, processes, histories, spell transformations and potion formulas in his mind were as solid as a frozen lake that condensed and grew bigger and bigger until it was completely frozen. firmly fixed together.

Gradually, Zhang Chun felt that his head was still very excited, but his ears and spine were getting hotter and hotter, making him really uncomfortable.

Maybe I have been reading for too long and I should take a break. If the afternoon is over, take a break and have a meal...

After Zhang Chun had this idea in his mind, he was completely unable to maintain such a highly focused state. In just a moment, he raised his head from the book.

"When is this? Why haven't my classmates come to the library to study yet..." Zhang Chun said to himself, looking at the empty library, he was very surprised.

Because students usually come to borrow books and study in the afternoon, but looking at the empty space, it seems that they haven’t arrived yet.

Zhang Chun shook his stiff neck and just wanted to stand up, but found a tingling pain in his thigh.

"Ouch."

Just as he said that, a voice came from behind him, "What's wrong with you?"

Zhang Chun turned around and saw Hermione looking at him with concern.

"Haha, it's okay, my legs are just numb." Zhang Chun smiled politely.

"...I told you not to call me that." Hermione pursed her lips.

"...I'm sorry." Zhang Chun had a dark look on his face.

The word "haha" really has a new meaning and cannot be said casually.

"I've never seen you study like this. You look like you're under a curse when you read so seriously." Hermione turned to the seat opposite him.

Only then did Zhang Chun realize that there was a whole table of towering books between him and Hermione. It looked like there were at least several hundred books.

"I read all this?" Zhang Chun couldn't believe it.

"That's true," Hermione curled her lips. "If I hadn't watched you take them one by one and read them one by one, I wouldn't have believed it."

"I didn't even notice you were right next to me." Zhang Chun smiled sheepishly.

"Not only did you not notice me," Hermione looked at Mrs. Pince in the distance and lowered her voice, "Mrs. Pince has been staring at you closely, fearing that you would eat all these books. You are so arrogant. It’s terrible to look at studying seriously.”

"Ha ha……"

"..."

"sorry!"

"Okay, you've been sitting for so long, don't you feel hungry or thirsty?" Hermione changed the subject.

Zhang Chun didn't think it at first, but after she said this, he really felt that he was thirsty and hungry now, "I'm really hungry! What time is it? Dinner is about to start, let's go eat."

Hermione shook her head helplessly, "Classmate Zhang Chun, you really have no concept of time when you read. It's already night, and it's been an hour and a half since dinner time, and it's even almost curfew time."

"Really? Why are there no other students nearby?"

"You have already gone back. If you delay for a while, Mrs. Pingsi should drive you away personally. But I think she is scared by your seriousness. I don't think she has ever seen such a hard-working student." Hermione glanced sideways at the administrator's desk in the distance and smiled.

Zhang Chun flipped through the system's negative emotion records. Wasn't it true? Mrs. Pingsi's negative emotions towards her have not stopped for so long in the afternoon and evening.

"It would be nice if I had eaten a little." Zhang Chun slowly stood up and pressed his stiff thigh muscles with his hands.

"I have good news and bad news. You want to hear the one first." Hermione said, tilting her head.

"Ok."

"I brought you raspberry cake, cheese and pumpkin pie, and I also brought one for your Chenchen."

"Okay! Bring it here, I'm almost starving to death." Zhang Chun's eyes lit up.

"Here's the bad news, your Chenchen has eaten them all, leaving nothing for you." As she spoke, Hermione lifted two empty plates from behind the stack of books.

Zhang Chun fell to the ground with a thud.

"Sorry, I didn't know your little white snake was so edible..." Hermione looked helpless.

"It has nothing to do with you, my life is miserable..."

Zhang Chun smiled bitterly and thought to himself: Who asked us to release an ancestor who had not eaten for more than 1000 years?

"Let's go, it's time for the library to close. Let's go back and see if there are any candies or anything else. At least let you eat something first." Hermione said and stood up.

Zhang Chun looked at her and suddenly remembered something, "By the way, Hermione, how is your memorization of the multiplication table?"

When Hermione heard him talk about this, she immediately smiled and said, "I've been able to recite it a long time ago, and I'm very proficient now. Didn't you say that if I can recite it, you'll teach me more complex arithmetic methods?"

"No problem, then it's mental arithmetic and abacus arithmetic. Which one should I teach you first?"

"I want them all!!" Hermione's big eyes were filled with light.

"Let's do the mental calculation first. That one is easier. Sit down and take a piece of parchment and record it..."

In the next short period of time, Zhang Chun asked Hermione to record in detail more than ten basic quick calculation methods of mental arithmetic.

"...Remember, you must memorize these formulas and methods, and then practice them repeatedly to master them." Zhang Chun warned.

Hermione looked at the quick calculation method of nearly two feet that she had written down, with a look of surprise and excitement on her face.

She raised her head and said to Zhang Chun, "You know, I prefer the arithmetic divination class to the divination class because it is based on strict mathematical derivation, more rigorous and more challenging." Bi Da, one of the ancestors of arithmetic divination Goras said that the essence of the universe is mathematics."

Zhang Chun looked at Hermione, who looked serious and excited, with interest, thinking to herself: How could this top student fall in love with divination methods like crystal balls and tea leaves?Nothing that has no difficulty, no reasoning, no challenge will be able to catch her eye at all.

"Actually, I think Muggle science may be more suitable for you. Pythagoras is not only the originator of arithmetic divination, but his school is also one of the origins of science. Look at how much Muggle science has created over the years. Miracles. You should learn more about real mathematics, the kind that is the mother of science."

"Your quick calculations aren't bad either."

"Speed ​​calculations are just small tricks. I mean advanced Muggle mathematics such as Newton's calculus. That's where you can show off your skills."

"Then what do you people in the East use for divination? Is it also mathematics?"

"We have Qimen Dunjia, Da Liuren and Xiao Liuren!"

"Qimen...Xiao Liuren...what is this?" Hermione was surprised and happy, and stood up unconsciously.

Zhang Chun only knew a little bit about Qimen Dunjia, but Xiao Liuren had really learned it.

"Let me teach you Xiao Liuren first, this is easier..."

Zhang Chun stretched out his left hand, and Hermione hurriedly came to his side.

Xiao Liuren's prediction method is very simple. When predicting, you only need to extract the month, day, and hour information at that time. According to certain calculation rules, use your left thumb to calculate the six palm positions in a clockwise direction to know the result.

Zhang Chun taught Hermione the corresponding positions of "Liulian, Suxi, Chikou, Da'an, Kongxu, Xiaoji" on the knuckles of his left hand. He was afraid that he would not understand for a while, so he found six images for each of the six words. Animals as metaphors.

"...For example, this red mouth is like a tiger. The tiger wants to open its mouth to roar and bite people, so the divination result is a bad sign.

...But you have to remember that the essence of Xiao Liuren is to randomly pick numbers, and you must not be deliberate. "

Hermione looked at him blankly, "I barely understood what you were saying..."

"Then you should first remember the basis that I use different positions of my left hand to do divination, and one hand can not only represent six meanings, but can even express eight, nine, twelve or even hundreds of thousands of things. This kind of intuition Once you use the fast algorithm, it will be much more convenient than holding a quill.

Did you know that we also have a finger speed algorithm, which is not divination, but uses a knuckle-replacing method similar to divination, and can directly calculate very complex arithmetic problems by hand, even the square root.I will teach you again when I have the chance..." Zhang Chun raised his left hand and talked.

But he didn't hear a response from Hermione next to him.

Zhang Chun turned around and saw Hermione's two big eyes staring intently at his face, as if she was lost in thought.

"Hermione, what's wrong with you?" Zhang Chun wondered, "Hermione...Classmate Hermione?!"

"...Ah, I'm sorry." Hermione woke up from a dream and stood up straight with a complicated expression.

"What's wrong with you?" Zhang Chun asked.

"Nothing... let's go first, Mrs. Pince is closing." Hermione turned her head hurriedly. After taking two steps, she stopped and looked ahead. After a while, she said Zhang Chun behind him said meaningfully,

"You know, my classmates at Hogwarts all think that I only study hard and use the method of acquiring knowledge to please the teacher. They don't understand my desire for wisdom, or they think it is just a pathology of sensationalism.

Harry and Ron were my best friends, but they both wanted me to love the Quidditch players as much as any other girl, talk about haircuts and common room gossip, and not spend all day in the library - not even me. They all began to wonder if they were an alien that would not be liked by others.

But seeing you, for the first time, I felt that I had like-minded friends around me. This was the first time that I saw someone worthy of my admiration among my classmates.

I feel like I'm not alone anymore. "

As she said that, she turned around, her eyes serious, but she smiled from the bottom of her heart,

"thank you for coming."
