I’m a Witch In Dongying

Under this kind of perturbed thoughts, Bai Shuiqiu completed the three or four questions marked by Keiko Kandaji one by one.

Then, under the girl's comment, some omissions were corrected.

At this time, nearly an hour has passed, and the two of them agreed to take a rest first.

While relaxing, Bai Shuiqiu gently rubbed his temples with one hand, leaned against the back of the chair, and heard Keiko Kandaro suddenly stir up a topic and whispered: "I heard about this recently. In a few days, the school’s board of directors is meeting to discuss where to go for this school trip."

"School trip?"

Bai Shuiqiu turned his head and glanced, aroused a little curiosity.

Study trips can be regarded as a major feature of Dongying Colleges. Basically, during the winter and summer vacations, major universities across the country will organize students on campus to travel to some places for learning purposes. According to the themes and categories of travel, the destinations are also different.

Generally speaking, Kyoto and Nara are the places where college students go on study trips. These two cities have a large number of historical sites and cultural heritage, which are very suitable for students to visit and learn to learn about history.

Next are Tokyo, Hokkaido, and Kyushu. These are either prosperous and magnificent international metropolises or remote areas close to nature, allowing students to experience the style of different regions.

As for the units for study trips, most of them are divided by class, and some travel together in groups or the whole year.

Of course……

All of the above are the routines of public schools.

Because private schools are richer, they often travel abroad. Areas such as the Hawaiian Islands and Northern Europe are popular choices. After all, Dongying has visa-free licenses in many countries around the world. Even students who are still in school can easily go abroad to play and increase their knowledge.

"Well, if nothing else, the time should be just after the summer vacation."

Facing Bai Shuiqiu's slightly puzzled gaze, Keiko Kandaji smiled and said softly:

"When I met Teacher Tianzhu at school a few days ago, I heard her say that the location of this school trip may be Kyoto. It's a coincidence that it’s the same place as Qiujiang where you participated in the national competition. Maybe we still have a chance. , Go watch your game with your classmates."

Mime private 469

"Really... it sounds pretty good."

Bai Shuiqiu also smiled, thoughtfully.

Keiko Kashiro's words reminded her a little bit.

In fact, in the memory of the predecessor, there were also one or two impressions about school trips, both of which were experienced in middle school and elementary school. But because they were still very young at the time, the school didn't dare to organize them to go too far away. The locations for several school trips were limited to Chiba Prefecture.

Among them, the one that impressed Bai Shuiqiu was when he went to Tokyo Disneyland with his classmates in the national hour...

——Although the word "Tokyo" is hung in the name, the geographical location of this park is actually in Urayasu, the westernmost city of Chiba Prefecture. The relationship between the latter and Tokyo is roughly equivalent to the Yanjiao of China To the imperial capital.

Since the establishment of this Disney park in the 1980s, it has maintained a high level of popularity and passenger flow. Except for the people of Dongying's own country, a large number of foreign tourists come to visit each year. It can be regarded as Chiba Prefecture. A fairly well-known attraction.

Of course……

Bai Shuiqiu's impression is not on those amusement facilities.

When she was a child, because she was thrown by her parents to her grandparents early, and she was born with the ability to see ghosts, her personality was silent and withdrawn, and her relationship with her peers was not very harmonious. The amusement park, which is so attractive to ordinary children, is not very interesting to the predecessor.

What really impressed Bai Shuiqiu was actually...

"If I remember correctly, I seemed to have met a human trafficker at the time..."

Such things as child abduction and trafficking also happen from time to time in Dongying.

Children like Bai Shuiqiu in his childhood, who are good-looking, quiet and out of gregariousness, are easily targeted by traffickers.

Little children, no matter how vigilant they are, they can be tricked. A few cones or a pack of candies can cheat their trust.

If you really can't deceive, just take advantage of the adult's carelessness and just faint and take it away.

At that time, Bai Shuiqiu had encountered this kind of method. Fortunately, he woke up in the middle of being taken away by the traffickers, and then did not disturb those guys. He quietly broke free from the rope, and found another one that no one noticed. When the opportunity escaped, he calmly explained the situation to the school's leading teacher, and the panicked latter reported to the Urayasu police station.

The time this experience happened was about seven or eight years ago.

This is the two years when Bai Shuiqiu was sent to Narita City by her cheap parents.

Because after a long time, Bai Shuiqiu can't remember the specific situation in the middle, but probably the process should be like this.

Later, I heard that the police in Urayasu City detected the case, arrested the three human traffickers involved, and rescued several children who were abducted by them. Afterwards, they even called Tenmu Shrine to explain to Chiyo. After a while.

It is precisely because of such a past that Chiyo was so anxious when the Ogino Jun incident occurred in early April.

And now when I think about it...

When he was a child, Bai Shuiqiu seemed surprisingly calm in this incident, and he did not act like a child who was only six or seven years old.

On the contrary, Bai Shuiqiu now feels a little bit scared.

If her predecessor hadn't escaped in time at that time, then her current destiny would be in a completely different direction...

But the matter has passed after all. If she encounters this situation again, she will have enough confidence to deal with it. The existence of human traffickers is even more disgusting than the evil gangs. If given the opportunity, Bai Shuiqiu doesn't mind destroying these guys humanely on the spot.

When Bai Shuiqiu remembered secretly in her heart, Keiko Kandaji was also looking at her silently.

The girl seemed to want to say something, but when the words came to her lips, she hesitated and changed her words temporarily:

"I went to Kyoto with my parents several times when I was a child, and I know a little bit about it there. If you want to go out to play, Qiujiang, I can show you the way. Kinkakuji, Ginkakuji, Honganji, etc... …Are all interesting places."

"...Okay, Teacher Keiko~"

Bai Shuiqiu raised his eyes, put what he had just thought behind him, and then smiled at Keiko Kashiro, half-jokingly said: "I have always wanted to go to that city to play, if Keiko leads the way. , Then it couldn't be better."

The study trip time is usually about a week.

The schedule of the IH competition will not be too short.

It's rare to go to Kyoto once, so naturally it is necessary to make time to take a good tour in this thousand-year-old capital. From another point of view, this can also be regarded as a date with Keiko Kamishiro, although the occasion is a bit special...

"Ms. Keiko, it sounds awkward..."

Keiko Kashiro groaned a little helplessly.

But seeing the girl smiling and groaning, it was obvious that she was not disgusted with this ridiculous title.

On the topic of school travel, I will stop here for the time being.

Next, the two men withdrew their minds and did some homework for a while.

Considering that teaching too much content at one time will affect the memory efficiency of the brain, after finishing a certain exercise, Keiko Kamidai voluntarily ended the lecture, saying that Bai Shuiqiu should take some time to digest it, and wait for the next time. When you come over, continue on.

At this time, the time has come more than four o'clock in the afternoon.

After sitting for several hours, Bai Shuiqiu felt a little flustered in his body, and simply pushed aside the chair, and got up to move his muscles and bones a few times.

And Keiko Kamidai carefully helped her to collect the textbooks and draft paper on the desk, and put the pen that was used just now in the pen holder. In the process, the girl noticed the softness that was put aside by Bai Shuiqiu. Paper copies, and a few scratch papers sandwiched in the book.

"Hey, these geometric figures look so weird. Are they Qiujiang's exercises yourself?"

"Uh, that's actually..."

Bai Shuiqiu took a hesitant look here, and pursed his lips: "Those things are about the formation of formations. I have just started studying these two days... It has nothing to do with studies, Keiko, you don't need to care."

"Yes……"

Keiko Kashiro glanced again, opened her mouth, and couldn't help but said, "These calculation formulas, I seem to be able to understand...their meaning is calculated based on the limit integral of the volume of irregular figures. To determine the maximum boundary value that the formation can cover?"

"???"

Chapter 470:

Bai Shuiqiu was stunned.

She also went to university in her previous life and is no stranger to the term calculus, but because she is not a major in science and engineering, the things she learned have long been returned to the teacher. Now, I just know it roughly. As for how to calculate it, I'm at a loss.

However, Keiko Kashiro saw the meaning of these formulas at a glance, which is obviously not what mere "knowing" can describe.

"If I'm not mistaken, the ternary quartic equation in this integral formula is the arc curve around the matrix. The general figure should look like this..."

While talking, Keiko Kamidai pulled out the draft paper he had just used, thought about it, and drew a three-dimensional coordinate axis, and then simply sketched a few strokes to form a three-dimensional figure.

Bai Shuiqiu opened the soft-skin copy left by his aunt and grandma, and glanced at it in contrast.

The graphics on the soft leather copy are almost exactly the same as those drawn by Keiko Kamidai.

To say something different...

It is Shirasui Sana's hand-drawn graphics that also marked some special points.

These points are used to carve runes and place the eyes.

The layout of the array is very particular about the position and angle. Whether it is the two instruments, the four elephants, or the eight trigrams, they are basically symmetrical figures. Therefore, the arrays arranged according to these patterns are naturally regular. Followable.

And this law can be described by an equation.

so……

Shirasui Sana borrowed mathematical thinking to quantify the formation and enchantment.

The advantage of this is that it is clear and clear. You can use some laws of the equation to determine the coverage of the array method. If it’s more complicated, you can also combine the position of the array eye and the strength of the spiritual power contained in each rune... etc. as parameters to calculate the weak points of the array, and then find the one that maximizes the effect of the array. Method.

The downside is...

"Dare to learn a formation, still need to have enough mathematical foundation?"

After trying to understand this, Bai Shuiqiu opened his mouth, a little wondering what to say.

Keiko Kashiro was equally shocked.

This girl probably never thought that the formation of the supernatural level could be combined with modern mathematics in such a way...

"Qiujiang, among your practitioners...do you have many masters of this method?"

"No, as far as I know, there is probably only Grandma Sana..."

Bai Shuiqiu shook his head.

Among the people she knows, there are not too many who dabble in the formation. Suzuki Zhu hopes to count as one. Some time ago, in the Baidiwan tunnel, the formation that gathered the yin spirit was managed by this girl to get rid of it. .

In addition, Asakura Mami should also have good formation skills, otherwise she would not be sent to deal with Lantern Mountain. However, Bai Shuiqiu and her have not officially met, so she has no specific understanding of the level of this girl. .

At least from Suzuki Zhuxi's mouth, Bai Shuiqiu has never heard of the use of mathematical formulas to assist the formation.

"Qiujiang, would you mind letting me read the contents of this note?"

Keiko Kashiro turned her head and asked cautiously.

Facing the girl's question, Bai Shuiqiu hesitated for a while before nodding.

"It's definitely okay, but don't mention it to others, because the content in this note was made by Shirasui Sana, a senior of my Shirasui family, and it is not strictly my thing..."

"Yeah, I know. In other words...Senior Shirasui Sana you are talking about, is the older sister of the grandmother of the thousand generations? I seem to have heard my grandfather mention this name before?"

"Yes."

The Jindai family also lived in Narita for a period of time, and Jindai Fumyama is a generation of Shirami Sana, so most of them have met. It is natural to mention a few occasionally in front of my granddaughter. . Therefore, Bai Shuiqiu only briefly explained a few sentences.

"So, Senior Sana is also a witch with powerful spiritual power, just like Qiujiang you?"

"No, my level is far worse, but it's a pity that the red face is fateful. If my aunt can live to the present..."

Bai Shuiqiu sighed silently.

While talking, Keiko Kamishiro had already opened the soft copy, looked down at the text on it, and said softly: "This kind of thing is impossible. What will happen if my mother is still alive, but things are over, and meaningless fantasy can't change reality..."

When talking about this topic, Keiko Kashiro lowered his eyes slightly.

In a sense, the nature of the deaths of Shirami Sana's mother and Kanda Keiko's mother is the same. Neither is normal birth, old age, sickness or death, but because of an accident and died young.

The former was to deal with the black mud and was killed in Lantern Mountain.

The latter was due to the actions of the Wild Mountain Club and died in a car accident in the rush a few years ago... This childhood loss of her mother is undoubtedly a scar in her heart for this girl.

"Keiko, you..."

Bai Shuiqiu opened his mouth, still thinking how to comfort her.

Seeing Keiko Kandaro raising her head, Zhanyan smiled: "If you don’t say this, things in the past can’t be changed, but Qiujiang, you have to pay attention to your safety. You don’t have to force yourself when dealing with those supernatural events. Yes. If anything goes wrong with you, my grandmother and I will be very worried...

And Asuka and them too. "

When talking about "worry", Keiko Kandaji's face blushed slightly, and then quickly added.

But the interruption between the two paragraphs has already revealed the meaning that I want to express very clearly.

Bai Shuiqiu heard it in his ears, touched his nose a little unnaturally, and replied in a low voice, "I see."

"..."

Next, neither of them spoke again.
