Chapter 1094: The Coded Note to Seal the Monster

After returning to Teitan High School, Yuya placed the bag of lime directly on the edge of the playground, and then asked Wakasa Rumi to notify the physical education committee member to draw the necessary lines before class.

I went to the office and borrowed Mr. Mizuhara's printer, and printed out the note I had taken with my phone.

The original note was to be taken away by the police as evidence, but there was no way to keep it.

Because the note was quite long, it attracted a lot of people's attention as soon as it entered the classroom.

A boy joked, "Kamiya, it's just a physical education class, do you really need to wear a hanmaki?" (A hanmaki is a scarf, mainly used to boost energy and fighting spirit. The most common one is the white strip tied on the head during sports games.)

Some people also noticed that this bowl was made of paper and wondered whether it would be durable.

Yuya casually explained that this was not a bowl scroll but a code paper, and many people immediately lost interest.

A few people came over to take a look, but they couldn't understand what the text meant at all, so they gave up - not everyone was interested in reasoning and deciphering the mystery.

Yuya returned to his seat, and Miyano Shiho leaned over and asked curiously, "Where did you get the code paper?"

Yuya briefly recounted the story of the old warehouse.

Miyano Shiho widened her eyes slightly: "In other words, you suspect that this code was used by those bandits to communicate?"

Yuya nodded: "That's right, but there is one thing I don't understand. If this code is really left for the accomplice, why didn't they take the note away when they went to the basement to look for something?"

More importantly, the 200 million in cash left in the basement after the stolen gold bars were sold.

It was only when he was printing the note that Yuya realized that if his accomplice had really gone looking for it, he should not have failed to find it.

Unless Yuya's initial guess was wrong, the person who entered the basement some time ago was not an accomplice, but someone else.

The other party just saw the bones, why didn’t they call the police?

Miyano Shiho said: "In short, as long as we decipher the code, we can know the truth? Do you have any clues?"

Yuya nodded slightly: "Probably a little bit, this note is a bit similar to the code stick used by the Spartans 2500 years ago..."

He took out a pen and rolled up the paper diagonally, trying to keep the words in one line.

"Uh..." Youya scratched his cheek. Although the words were arranged smoothly, the words combined together seemed to have no special meaning and he could not understand them at all.

He tried changing pens of different thicknesses, but the result was the same.

"It doesn't look like a password stick." Youya scratched his cheek.

Miyano Shiho looked at the note and asked a question: "I see that the characters on it are all Chinese characters composed of side characters and radicals, but it seems that there is no such Chinese character?"

Yuya nodded: "Yes, that's why I thought of using a code stick. After rolling it up, it can form another text. I didn't expect it to be wrong."

Yuya spread out the paper and looked at it again.

Suddenly, he found that there was something special about the code on the note.

He carefully compared the radicals in the left column and found that there were seven types, namely: 吾、攵、会、里、工、本、舌;

The column on the right is Moon, Mars, Water, Wood, Metal, Earth, and Sun.

Yuya said thoughtfully: "Come to think of it, does the column on the right look like the seven stars corresponding to the day of the week?"

Miyano Shiho took a look and nodded in agreement: "Really? They are exactly the seven stars corresponding to Monday to Sunday. I'm glad you figured it out."

Yuya touched his chin, then took out a piece of white paper, marked out a 7X7 table, and then wrote the right column representing the Seven Stars horizontally at the top of the table in the order of Monday to Sunday, and then wrote the left column of radicals vertically on the left side of the table.

"In that case, starting from Monday..." Yuya thought for a moment, then combined the Seven Stars with the seven vertical radicals into Chinese characters and filled them in the form.

The table becomes, from a vertical perspective, the Chinese characters composed of the moon and the seven radicals, the Chinese characters composed of the fire and the seven radicals, and so on...

These seven Sundays and seven radicals, neither more nor less, just fill up the 7X7 table.

Miyano Shiho propped up her chin and looked at the table with a surprised expression: "Is this the decryption table? Why do I feel it looks more like a course schedule?"

Class schedule? Yuya was stunned, and suddenly remembered that it was the tattered class schedule that Bu Mei found in the old warehouse.

Could it be that it was not a course schedule left behind by a student, but a decryption table used by robbers?

Yuya sent a message to Conan, asking him to take a photo of the class schedule that Ayumi picked up and send it to him.

Conan replied quickly, and in addition to the class schedule, he also added a sentence: It seems that your progress in decrypting is ahead of mine, but I will not give up!

Yuya smiled, clicking on the photo to enlarge it, then comparing it to the table he had made.

Soon, he discovered the secret.

In addition to the top row representing the seven days of the week, the left column lists seven courses, namely:

Guo (Mandarin), Suan (arithmetic, also known as mathematics), She (social studies), Li (science), Tu (same as diagram, handicraft class), Ti (physical education), but the last class, Xue (activity class), was filled in on Tuesday, in the fire column, with a cross on its left.

At the same time, science subjects on Thursday and the last class on Sunday were also marked with a cross.

"It seems that my guess is correct," Youya smiled slightly, "The characters on the left column of the note happen to be the radicals of one of the characters in these subjects."

"What's next?" Miyano Shiho asked curiously.

Yuya thought about it, picked up a pen and started writing on the table: "There are 49 cells in total. Excluding the three with crosses, there are 46 cells left. There are also 46 basic characters of kana. If we mark them in order..."

Yuya finished writing quickly and ended up with a table of kanji with kana marked on it.

Miyano Shiho looked at the form, a little confused: "So, what is the answer to the code?"

Yuya smiled slightly: "With this decryption table, I should be able to understand the code on the code stick."

"I'll read the code, and you can help me check the pseudonym."

"Okay." Miyano Shiho nodded, picked up the form and looked at it carefully.

Yuya rolled up the paper again and read the codes on it in order.

After a while, Miyano Shiho looked at Yuya with a confused expression.

Yuya also frowned slightly - although he successfully converted the code into kana, it simply could not be combined into a coherent sentence, and it could even be said that the meaning was unclear.

Even if you want to rearrange the kana, you can't do it without a reference.

Is my reasoning wrong? You couldn't help but wonder.
