As soon as the bell rang for school, Hikaru Kamikawa quickly picked up his schoolbag and began to calculate the spatial coordinates.

But at that moment, a hand grabbed his collar and pulled him back directly when he was about to go to the eleventh dimensional space.

"Don't try to run. Fukiyoshi said seriously, and then dragged him directly out of the classroom in front of all the students in the class.

Since Hikaru Kamikawa was caught, he became honest. He actually didn't want Teacher Xiaomeng to look at him with tears in his eyes the next day, and asked why he skipped tutoring yesterday, because he would definitely be killed by the classmates who liked Teacher Xiaomeng. Although Yueyong Xiaomeng is a bit natural as a teacher, she has gained huge popularity because of her sincerity.

"After school, the school library closes quickly. Go to a public library and study. Fukiyoshi said, regardless of whether he agreed or not, so he pulled him over.

"Hey, what about my opinion?"

"Veto!"

With a voice of rejection without hesitation, Hikaru Kamikawa resigned to his fate, and it seemed that he could only go back very late to see that my sister was so cute.

……………………………………………………………………………………

School Park City Public Library,A library named after the city with the prefix。 The entire library is 10 stories high and covers a very large area, with a claimed storage capacity of nearly 50 million books. Because there are too many books, many of them are stored underground, and when needed, they can be transported automatically by machines.

From time to time, there are discipline inspectors patrolling the library to ensure peace and order in the library.

It's a perfect place to study, and when Hikaru Kamikawa was in the park, he often came to blow the free air conditioner or read a book. Just scan your student card and you will be given permission to borrow books for free.

But Hikaru Kamikawa doesn't like to read very much, at most he reads comics.

As soon as I entered the door, I found that the free seats were full of students, all of them silently flipping through books, and even some people who seemed to be scholars were also looking up materials here.

"There don't seem to be any empty seats on the first floor, so let's start looking at the sixth floor. Fukiyoshi looked around and said.

In fact, the choice of floor also hides knowledge. Generally, the first five floors are overcrowded, and the second option is to go to the highest floor, and if you choose, the sixth to ninth floors are generally the least crowded.

The two took the elevator up to the sixth floor, and sure enough, they found a spare table around the corner. There was only one girl sitting there reading a book, but what caught Mikaru Kamikawa's slight notice was that the sleeve of her blouse was covered with the armband of the Discipline Commissioner, and strangely, there was a pure white umbrella next to her chair.

"Why do I have a bad premonition?"

Fukiyori was a little strange as to why he chose such a remote place against the wall, but he didn't say anything, just sat down next to him. Then, from the algorithm, the divide-and-conquer rule is generally used to find out the best algorithm......"

The theory of the blowing system began to talk endlessly, obviously mastering this knowledge point.

Kamikawa Hikaru listened a little foggy, and he really didn't know this knowledge point before, so he became serious and listened carefully.

Looking at the blowing system, she has a charm when she is serious. Although it looks serious, it's still the type that cares about others very much, and it's a person who is cold on the outside and hot on the inside.

"Do you understand?"

Suddenly, Fukiyori asked, and he seemed to see that Hikaru Kamikawa was a little out of sight.

"This,It should be ......" Hikaru Kamikawa answered very easily.,The question involving dimensions has a special understanding because I'm a person with spatial ability.,But it's also possible that it's because of the constant practice of spatial calculations in daily life.,So these questions can be fully understood just by looking at them once.。

"Hmm. Fukiyo nodded with satisfaction and said, "The answer is completely correct, so ...... next question."

After asking Hikaru Kamikawa a few questions in a row, he answered them perfectly, and closed the book.

Mitsuyoshi Kamikawa breathed a sigh of relief and was about to pack his things and go back, when Fukiyo took out another book from his school bag......

"There are five more homework to help you review. ”

“………… Can I see for myself?" asked Hikaru Kamikawa, not much hopeful.

"No way!"

The expected answer, the strong sense of responsibility naturally rejected his proposal.

In this way, it took a full two hours to review all the recent learning of the other five books.

"That's all for today, you're in good hands. I'll go first, and you should go back early. "Blow the watch on her wrist, it's time for aerobics, and she's going back quickly.

Hikaru Kamikawa stretched as he watched her leave, and out of the corner of his eye, he noticed that the girl was still reading silently, but occasionally seemed to look this way.

"I should go too, I've learned a lot of things today, such as the nearest point of high-dimensional space...... Compute," Hikaru Kamikawa muttered to himself.

Suddenly, he seemed to have a layer of realization in his heart, and what he had just learned seemed to be the formula that he could save by performing third-dimensional calculations. Moreover, a completely different line of thought is also offered.

I was a little excited in my heart, and I thought of that equation, as long as I brought in all the variables, maybe I could calculate the third dimension.

He raised his right hand and spread it flat, his hand open towards a book on the shelf.

Suddenly, the book slowly began to move in the air a little strangely, but it was very smooth, and there was no vibration at all. In the past, when an object was parked in the air, it was done by constantly turning the entire object upside down. Levitation in the air can be achieved by setting up two very close points in the air and constantly moving the object between the two points. And the downside is that gravity has to be taken into account, constantly changing direction to counteract the effects of gravity. Because of the small vector changes (gravity, direction of velocity of inertia, air resistance), it looks like the object is always vibrating slightly.

Now, gravity can completely change direction and become horizontal velocity.

Because, after adding another coordinate axis, you can already change the vector direction of an object at will.

The direction that originally required a few steps of 2D reversal to convert (the plane of the reference needs to be constantly changed) only needs to be referenced once with one more coordinate axis reference (you can use a surface of any shape for reference), and you can do it.

At that moment, Hikaru Kamikawa only felt a new door open to him......

"Hey, I'm sorry, I'm happy to see you playing, but ...... The use of power is forbidden in the library......"

The silent girl suddenly closed her book, stood up, and stared into his eyes.

"Discipline Commission Headquarters, Lv3 Fluid Manipulation Ability, Elenoah Anksun Heinaman, number 04111, now decides to fulfill the duties of the Discipline Inspector and officially arrest you!"
