I’m a Witch In Dongying

But overall there is no too complicated threshold. The main problem is the amount of calculation. As long as the method is mastered, it is as simple as translating the password according to the codebook. "

While speaking, Jiufeng Ziyuan explained the calculation process in detail to the floating board on the dial.

"..."

Twenty minutes later.

Bai Shuiqiu is still confused.

Her current feeling is that she seems to be back in the university class in her previous life, listening to the teacher on the stage explaining high math. In addition to the opening remarks, you can understand what it means. Later, when it comes to specific calculations, it's like listening to the heavenly book.

Even if I know that Jiufeng Ziyuan is very detailed and really wants to teach her the method, but Bai Shuiqiu's mind is like a mess. He only sees the other party's mouth moving. Can't hold things.

On the contrary, Keiko Kashiro listened very seriously. When the old monster finally stopped, the girl thought for a while, and said in deep thought:

"So it's like this..."

"Although there are a few terms in the middle, I still don't understand what they mean, but I already know what's going on."

Bai Shuiqiu: "???"

What do you understand? ?

Under Bai Shuiqiu’s surprised gaze, she saw Keiko Kamidai took out a soft leather sheet from her shoulder bag and spread it out on the coffee table, then took off the pen cap, and put the zodiac on the paper first. List the five elements, gossip, etc. separately, then connect several of them against the floating board on the compass, and write them one by one below.

"If my understanding just now is correct, the calculation process is probably like this, right..."

Keiko Kandai copied the soft leather to Bai Shuiqiu's side and handed it to Bai Shuiqiu, and said softly: "The first batch of floating boards that stopped just now are Chou, Yin, Tatsu, Si, and B, C, and Kui. Take them first. Arrange them in the order of appearance, then connect them in pairs, and then perform quantification..."

These words are rare words that are not commonly used in ordinary times, and they are somewhat confusing when they are spoken by Keiko Kamidai.

But this is obviously not the point.

At the step of "Chou Yin Chensi", only Chinese characters were written on the paper.

Then after a few steps of calculations, I didn't know what happened, and suddenly it became a row of numbers and letters.

After a few more conversions, a row of matrix equations and linear equations...

"...According to the solution of the quintic linear equations, a total of five values ​​were obtained, namely 0, 87, 209, 236, and 319. These four values ​​should be the suspected "shades" mentioned by Mr. Shion just now. The angle of the location.

The first value may be the Tenme Shrine we are currently in. Because it is at the origin, the displayed angle is 0. It probably refers to Shion-teacher you, or Shikigami next to Xiaoqiu.

The last four are arranged in clockwise order, namely three o'clock, seven o'clock, eight o'clock and eleven o'clock, corresponding to the east, southwest and northwest of Tianmu Mountain, respectively..."

"As for the distance, it's the same, except that the original parent is turned into golden wood water fire, and then the algorithm is slightly changed..."

"And the intensity of Yin Qi..."

When he reached a certain step in the third item, Keiko Kandaji hesitated, and firmly grasped the ballpoint pen in his hand, but it did not fall.

Jiufeng Shion saw in his eyes, and promptly raised a few words.

Of course…

Bai Shuiqiu still didn't understand.

But Keiko came to understand, bit her teeth for a while, then bowed her head again, crossed out the few lines of equations that she wrote just now, and then recalculated.

Unknowingly, four pages of paper have been written on the soft paper sheet.

This is still in the case of a few simple steps, because most of the additions and subtractions within four digits of the square, Keiko Kamidai relies directly on verbal calculations, even if it is more complicated, only formulas are listed to solve the problem. If you write down all the calculations in one to five to ten...

"..."

Bai Shuiqiu silently turned his head and glanced at the rain girl standing diagonally behind him: "Um... Green sister, do you know what they are doing?"

"..."

Yunv looked at the soft leather notebook on the coffee table blankly, then glanced at Bai Shuiqiu, without saying a word.

But even so, it is not difficult for Bai Shuiqiu to guess from the latter's silent posture what Yunv's answer is—

If Shirasumi Sana, a magical and mathematical genius, stood here, he would probably be able to understand the communication between the old monster and Keiko Kashiro. After all, Keiko is not using any advanced algorithms that have been newly developed in recent years. They are all basics. The content of mathematics. But for Rain Girl...

Although this green-clothed woman has followed Sana for a while, not every monster has so much leisurely thoughts about Shiufeng Shion...

Next, Keiko Kashiro worked out the calculation for another ten minutes.

During the period, I asked Jiufeng Shiyuan twice. After the last line of formula was written, the girl put down the signature pen in her hand, crossed her hands and ten fingers, and stretched her arms:

"Finally finished the calculation. The method is indeed not difficult, but the calculation is a bit large. After you are proficient in the exploration, you can probably figure it out quickly like Teacher Shion."

"Ok…"

Bai Shuiqiu rolled his eyes, not knowing what to say.

If this level of calculation is only "a bit" large, what can be called "extraordinarily" large?

It can only be said that people cannot be generalized.

Jiufeng Shion won’t talk about it. It’s a monster in itself, and its body contains extremely majestic demon power. Therefore, both the body and the mind are much tougher and more advanced than human beings. The result can be calculated by verbal calculations. Curious. And Keiko Kashiro was purely because of his superior intelligence, so at this age, he had mastered these mathematical knowledge that would normally be accessible to university or even higher levels.

If this girl has the same psychic quality as Kanako, even Asakura Asami's level...

I am afraid that the achievements in the magic arts will be limitless.

"Don't worry, Qiu Jiang."

Keiko Kashiro seemed to see Bai Shuiqiu's thoughts, patted her wrist lightly, and said softly:

"I learned this method first. In fact, it's the same as Qiujiang you learned, and then I can teach you slowly. If you think it's too troublesome, then just let me do the calculations for you. I think Teacher Shion would be happy to help too, right?"

"Ok."

Jiufeng Shion put his hands on his chest, his eyes stopped for a moment on the backs of Bai Shuiqiu and Keiko Kandaji's overlapping hands before he smiled and nodded:

"In fact, the difficulty of what we are doing now is indeed very small. After all, it is only to explore the rules and implement calculations on the basis of the existing algorithms. The Hua Tiantian who made this compass back then is the real one. There is no genius in it.

Regardless of his own cultivation level, just relying on this body's practice in Yishu, it has been able to make most of Dongying's Onmyojis beyond reach. "

"makes sense…"

Bai Shuiqiu nodded.

Then he carefully considered Keiko Kaminari's proposal in his heart.

From the bottom of her heart, she didn't want to involve Keiko Kaminari in events related to the "Yin Yuyu".

Tonight’s "Hundred Foot Incident" was a passive collision, which was impossible, but when there were other options, it was another matter to actively pull the latter in. The degree of danger of this kind of thing is too high, even if Keiko Kandaji is in good health and is not troubled by congenital heart disease, Bai Shuiqiu doesn't want to do it.

but…

If it is just a simple calculation, there is not much risk.

I can’t get my heartbeat fast because I can’t figure it out...

This aspect was originally not Bai Shuiqiu's strong point. I really need to study from the beginning, and I don't know how long it will take to master it, and this happens to be what Keiko Kamishiro is good at. Now that the girl has learned the calculation method from the old monster, it is better to leave the work to her to handle it and act as her own guide.

And as long as he practiced the technique at ease and prepared to face evil things.

With this thought, Bai Shuiqiu hesitated for a while before finally nodding and agreeing.

Keiko Kashiro smiled, her eyes narrowed into crescent moons.

On the other side, Jiufeng Ziyuan slightly pushed the compass toward the coffee table.

"Alright. Then I will leave this thing with you, Xiaoqiu, and let you and Huizi classmates take care of it."

"Anyway, this thing is dusty in my hands, and I don't bother to pay attention to it from time to time. If something really happened, you can figure it out first, and then notify me. I will use that feather to detect it as soon as possible. To Xiaoqiu's position."

"This...Thank you Shiyuan teacher, then."

Bai Shuiqiu thanked him very seriously.

In any case, this compass was also a product left by the Hojo clan during the most prosperous period of magic arts, and it was related to the Hua Tiantian teacher. It has been circulated in the imperial house for many years, and it is also a very valuable artifact. Perhaps when they were in Kyoto, the Hojo clan was able to accurately find the location of the old monster and launch the assassination on the night of the rainstorm, which was related to the existence of this magical artifact.

And now, although the old monster said "kept in safekeeping", in fact he was already going to give her this thing.

This kind of favor can be said to be quite heavy.

By the way...

Bai Shuiqiu suddenly recalled a detail--

I heard that the old monster said that the royal onmyoji who was responsible for keeping this compass and guarding the safety of the royal blood in the Kyoto imperial palace was called Masashi Hojo?

Mime private 704

Bai Shuiqiu once heard the name "Hojo Masashi" elsewhere.

—During my trip to Kyoto, the old monster used to shake off the conspiracy of the Hojo clan and the ghost clan in the presence of Hojo Kanshi and his entourage who went to the Raulei Valley to carry out the assassination. The Hojo Masashi was mentioned in it. This is the imperial onmyoji who was responsible for guarding the Kyoto imperial palace when Prince Akane was murdered in a conspiracy.

Of course, this piece of information was not heard by Bai Shuiqiu personally, but was relayed from Keiko Kamidai.

Because she was sitting on the big peach tree in Luolei Valley, charging Mingleiyu, but couldn't see the scene where Jiufeng Ziyuan and Hojo's family Tuqiongdi saw with her own eyes...

But this is not the point.

The point is...

If Masashi Hojo ever took charge of this compass, then theoretically. He should be able to detect the actions of Jiu Tun Boy and his party at the first time. Even if the latter has any special concealment skills, at best, they can sneak into the Kyoto city without being discovered. When they get close to the periphery of the Kyoto Imperial Palace, no matter how subtle concealment ability is, it should show clues.

After all, with the exception of a few outliers such as Ibaraki Doko, the ghost race itself is not a monster race that is good at spells.

Moreover, the area of ​​the Kyoto Imperial Palace is about 100,000 square meters, and the average length and width are less than one mile, which is the most accurate range of the compass's detection results.

From these points...

The extent of Hojo's negligence in that incident was really a bit blatant. Although it is the Dajiangshan Ghost Clan who really came forward to murder Akui, it is hard to say how much the Hojo family played a role in it. Maybe these guys want to kill Prince Akine more than Jiutun Boys...

In this way, the old monster chose to give this compass, which was closely related to Akui's death, and give it to her, which may have some other meanings—

Maybe, to avoid seeing things and thinking about people?

Anyway.

Whether this compass is used as a cultural relic or as a magic weapon, its value is beyond doubt. Since the old monster is willing to give it out as a gift, Bai Shuiqiu is disrespectful.

But considering that this thing is a precision artifact and is easily damaged, Bai Shuiqiu wondered if he had to find a way to make a container to store it, so as not to bump and bump it when it is used in the future, and then affect the floating plates on the plate. The detection accuracy...

Compass has finished talking about it, and the meeting room is quiet again.

Keiko Kamidai took out her mobile phone from her pocket, opened the map software, and compared the directions calculated just now to find the corresponding location on the map.

This job is actually not easy.

Since the angle was not marked on the map, Keiko Kashiro did not carry a protractor with him, so he could only make a simple visual inspection, and then based on the scale of the map, he roughly marked the distance and circled an approximate direction.

"The place calculated just now should be this area, this area, and here..."

Keiko Kashiro handed the phone screen to Bai Shuiqiu, and drew a few red circles with his fingers:

"From the map, it is basically not the most densely populated neighborhood, which is quite fortunate...

However, the coordinates obtained in this way are not accurate enough.

When I go back in the evening, I will find a way to compare the panoramic map on the computer and calculate the latitude and longitude of those points. The screen of the mobile phone looks too inconvenient... Well, maybe I can try this time. Summarize the calculation formula, input it into the computer, and see if you can use it to improve the efficiency of the calculation. "

"...Also."

Bai Shuiqiu nodded.

Speaking of which, there are no computers in Tenme Shrine.

At the age of a thousand generations, I have passed the stage of being interested in this kind of high-tech products, even watching TV less. Although Bai Shuiqiu is relatively young, because he is in middle school, he has no need to use a computer. Of course, the main reason is poverty, and there is no need to spend money in a place that is basically not very useful.

And now...

The income from the shrine is definitely enough, but Bai Shuiqiu usually practiced archery and spells is already very time-consuming, and has no spare time to play on the computer.

Therefore, this matter can only be done by Keiko Kamidai. The calculation process is mainly cumbersome. As long as the formula can be clarified and the computer can be used to replace manual calculations, at least part of it should not be difficult.

The topic of the compass has come to an end here.

At this time, the sound of Chiyo's footsteps appeared at the entrance of the meeting room in good time, and then he saw the old man leaning in from the outside of the corridor, and said gently:

"Ms. Shion and Keiko shouldn't have dinner yet. I just prepared a bit of thick tea and light rice here. Please stay and have a meal together?"

"good."

Bai Shuiqiu nodded in response, then turned to look at the compass in front of him.

Before she started to carry it, the old monster raised another hand and copied it to the bottom of the compass. He lifted the tens of kilograms in the air by a few inches: "I will help you take it back to the bedroom. Bar?"

"Eh?"
