Caesar's Shift Code -

Because Caesar is said to have been one of the first ancient generals to use encrypted letters, this encryption method is known as the Caesar cipher.

This is a simple encryption method, and the density of this cipher is very low, and it can be deciphered by simply counting the word frequency. Nowadays, it is also called a 'shift password', but the number of digits moved is not necessarily 3 digits.

The use of ciphers can be traced back to ancient Rome, and the Gallic Wars describe that Caesar used ciphers to transmit information, the so-called 'Caesar cipher', which is an alternative cipher, in which the letters are pushed back by 3 digits in order to play an encrypted role, such as replacing the letter A with the letter D, and replacing the letter B with the letter E.

It's just that here, the text [Calisto] given to him by Mr. Sayu does not have this meaning, after all, if you want to use this kind of password, it is best to change it to English.

However, I heard that Sayu's English doesn't seem to be very good, and if you reluctantly use English, it will be troublesome if you misspell it.

This is a matter of life and death, and he can't possibly use something he is not good at to complete this exchange.

Besides, if Mr. Sayou really gives the password to himself, that is, the information composed of English to himself, if the word frequency cannot be counted, then it will not be able to be decrypted.

At the same time, maybe Mr. Sayo came over not with the Caesar code for decryption, but with the Virginia code or the Vigenar code?

Iya knew that this was due to the fact that he had been in charge of the manga related to these decryptions, but he couldn't remember all of them now.

All in all, all kinds of possibilities exist, and Sayu will give this text to himself, there must be some purpose.

There is something you can think of and others can't think of the meaning of zài.

If you are an efficient person, you must solve this puzzle in order to improve the efficiency of the rescue.

That's right. By the way, until now, Yi Ye remembered that he hadn't used the easiest means of searching on the Internet.

It's just that this method is not so efficient for Yiye, because the things on the Internet are not necessarily real, and in addition to this reason, it is due to the fact that Yiya is not good at using the Internet.

It's really a secret of hers, a secret that no one knows.

Although you can use your mobile phone, you can also fiddle with your computer to upload manga texts, but once you want to do anything other than these two things, it is difficult for Yiye to do it.

Don't like computers. The colleague is also not computer savvy.

Turn on the phone to enter the search page to search, and after typing in the four words, you get a lot of information.

A dizzying amount of information.

This is one of the drawbacks of the Internet, there is too much information, which makes the human brain selectively filter out some useful and useless information when processing.

There is a lot of content on the page, including football stars, club ministers, diplomats, etc., almost all of them are foreign names and place names.

Yi Ye doesn't think that this text is to tell him the names of people and places in foreign countries, and there must be more out-of-the-way information.

Thinking about it, he got out of the car, and when he saw the bus leave, he entered the hospital.

There are many patients walking in the atrium, after all, today is a rare good weather.

The harsh sunlight shone through the gaps in the leaves. The whole body becomes warm.

Looking to the side, you can see flower beds and grass, and the dew on them means that they have just been watered.

Some of the nurses greeted them, and Iya responded politely.

Iya doesn't like Iya very much. This feeling can be said to be similar to not being good at the Internet.

The automatic sensor door opened, and after going to the counter and asking for Sine's name, I learned that it was in Ward 32 on the second floor.

Since it was only the second floor, Yi Ye did not choose to take the elevator up. However, as long as it is not on the tenth floor, Yi Ye probably will not choose to take the elevator.

Small spaces do give people a sense of security, but in turn they can give people a sense of constraint. Maybe it's my own psychological problem.

But no matter who you are, you have a little psychological problem, it's just that you can't be strict.

Yan zhòng's psychological problems will be classified as mental illness.

Anyway, after going through the guò safe passage to the hospital room where the sine on the second floor was located, Iya knocked on the door with his hand.

"Inugami-kun?"

"Come in."

Hearing the response, Iya pushed open the door and walked in.

I met him at a discussion held by the company.,Due to the animation of a manga.,Iya was called over for an internship.,And it just so happens that Sine is also an intern character.。

Then, for reasons that weren't much worth mentioning, the two became friends.

"I'm not going to choose to beat around the bush, but just say the reason why I'm here, is Inugami-kun's girlfriend back now?"

"No, not yet, so what's the reason for being here? There's news from Sayou? ”

"That's exactly what it is, this is a text message from Mr. Sayou, can Inugami-kun see something?"

"This is...... Calisto? Suggestive of a class of text? But since you have the opportunity to text a text, you should call directly, if only you could know if he and Cosine are together. ”

"I think there's a great chance to be together, and came here to ask if you know what that means?"

"I can't literally look at the content, I guess it has a certain meaning, implication or something, Calristo, Carristo, maybe it's a person's name."

"I looked it up on the Internet and there are a lot of names......"

"That's not the case, Battlefield Hara, think about it carefully, if they can only send this kind of hint text, it shouldn't mean so many famous people in modern times."

"Modern, the same name?"

Iya repeated the words of the sine, and something came to mind.

Carristo, if not modern, then there is only one choice.

It's not a decryption.,It's just that Yi Ye forgot about it all of a sudden.,It's really stupid to think about it like this.。

"In ancient Greek mythology, there was a beautiful fairy named Calisto."

"Got it?"

"Then, because of Hera's jealousy, Zeus turned her into a bear to protect her, and the seven famous stars of Ursa Major can be seen in the northern sky at night, the spoon-shaped Big Dipper."

"That's right, Ursa Major, yes! I've heard the name Ursa Major, no, I've seen it, that's where Cosine and I used to go for work, but we didn't stay in the end, I remember it was near the suburbs. ”

"I'll go now."

"I'll go too."

Putting the phone away, the two of them set out to act. (To be continued!)
