Yumi Miyamoto heard the whisper of Ceciaki, and immediately jumped to Hachitsuka Tsukiri, asking him suspiciously if he had hidden the envelope on his body.

"What are you talking about? How could I do such a frugal thing?" Hachizuka Turi looked embarrassed and angry, feeling that he was insulted.

Yumi Miyamoto was startled by his reaction and couldn't help but wonder if he had really misunderstood this old man, but would a normal old man do such a thing? He was like a fan.

"After that being said, don't you think this room is a little cold?" Haibara Ai rubbed his arms.

"Grandpa, can you turn on the heating?" Conan asked.

"I want to turn on the heating myself, but the air conditioner has been broken since yesterday and I can't turn on it at all." Hachizuka Tsukiruo smiled and said, "Sorry, let it be patient."

Conan frowned because if he remembered correctly, he felt quite warm when he first came into the room, indicating that the heating was originally on.

Chen Xing looked around and couldn't find the air conditioner remote control.

Tiger Six of Bazhong yawned and was secretly proud.

"I really want to say it, is this the code you think of?" Miyamoto Yumi fiddled with the code paper between her fingers.

"Yes, why do you have to doubt?" asked Hachiro Otaku.

"Because this code is not handwritten, it is a photocopy, right?" Miyamoto Yumi snorted, and said in a bad tone: "So what I want to say is that you actually got this code paper from someone else's hand and then took it to photocopy."

Hachizuka Tsukiri said lightly: "This piece of paper is indeed a code I wrote down myself. The reason I used it for photocopy is that I was bored and wanted to do this."

But in fact, there is no photocopier in the room. If you want to copy, you have to walk to a convenience store about ten minutes away.

Conan took out his cell phone and looked at the photo of the code paper. He had only taken photos before, but forgot to confirm whether it was handwritten or photocopy.

He also noticed the suspicion at this moment - the papers on the photocopier are all rectangular, but the code paper is square.

"It was this old man who cut it into this shape, which means that he used it to copy it was not on a whim, but there was a reason to have to copy it. Don't you want people to see the traces of the draft on it?" Conan thought to himself.

"Since this is a code you wrote by yourself, at least give me a little hint, right? Just a little." Miyamoto Yumi clasped her hands together and said with hope.

"No need to give me any tips. If you want to marry a celebrity in Taige and really plan to compete with him, you will be able to untie this code immediately." Eighth Torachi Tsukiru said in a deep voice: "As long as you have enough awareness and want to become a real couple with him."

"Couple?" Conan's expression moved.

The three little ones were playing Monopoly with chess, and the chess piece fell from their hands onto the board, making a clatter.

Ayumi said disappointedly: "It's 1 again, and I'm still a little short of reaching the finish line."

"It was obviously very lucky at the beginning." Yuan Tai smiled.

Mitsuhiko comforted: "After all, life has ups and downs."

"Have you rise and fall? Wait, I remember that the code paper was found in the trash can." Conan suddenly realized, so as long as the code paper is made into that shape...

He jumped up, grabbed the secret code paper from Miyamoto Yumi, and folded it on the table.

Chenxiong and Ai Haibara came over curiously, wanting to see how the detective unzipped the secret code.

"Conan, have you found any clues?" Sato Mikako said expectantly.

"How is that possible? I think he's just playing." Yumi Miyamoto curled her lips.

"But this child is different." Mikako Sato was very confident.

Yumi Miyamoto said speechlessly: "Look at him, are you decorating the code now? It's obviously like origami I often played with when I was a child."

Mikako Sato suddenly lost confidence.

But the two of them who didn't care about it also looked serious when they saw Conan gradually folding the paper into shape.

"So amazing, it has become a text!" Sato Mikako exclaimed.

Bazhong Huliu subconsciously stepped forward, but for the sake of face, he stopped again.

"Okay, Yumi, quickly enter the eight-digit number." Sato Mikako said hurriedly.

Arimi and the others came over and looked at the things that Conan folded for a while, but couldn't find the so-called eight numbers.

"Those words are not numbers, but Katakana, right?" Ayumi hesitated.

"When most adults see that, they will recall the eight-digit number." When they said this, Ai Haibara looked up at someone, and he could guess from his expression that he was not in this list.

Chen Xing's old face turned red.

Azumi said in surprise: "It's really the same as Xiao Ai said. Miss Yumi easily filled in eight numbers."

"But that code is obviously Katakana." Yuanta looked puzzled, "If you really want to say it, why would those Katakanas be released if you fold the code paper?"

"He gave clues from the beginning," Conan said: "Whether it is a clue that is specially used to take the code paper for photocopying or throw it in the trash can."

"You said photocopy?"

"What's the matter that will reveal it without photocopying?" Conan asked.

Haibara Ai thought for a while, "Is it a trace of the draft or a trace of the correction?"

"Crench?" Chen Xing guessed.

"That's right." Conan lit up the origami in Liang's hand. "If the code paper has creases from the beginning, we will know how to fold it immediately, so we can't act as a code."

Mitsuhiko realized it later, "But if there were no creases, you wouldn't know how to fold it."

"That's why the old man threw the code paper into the trash can." Conan chuckled, "There is an idiom."

"The crane stands out from the crowd." Haibara Ai said indifferently: "It means that among ordinary people, there is an outstanding talent or a person with a very outstanding appearance."

"The so-called flock refers to the place where the trash is thrown. Throwing the coded paper into the trash can is a reminder to fold the paper into a paper crane." Conan explained while doing origami, "so I folded the side with the code upwards into a paper crane like this."

After folding it, he showed the paper crane in his hand to everyone, "There are two words "root numbers and 5" on both sides of the left and right."

"What is root number 5?" Azumi asked.

Conan said: "After squared squared, it will become a number of 5, called the square root of 5 or root number 5. When you read junior high school, the teacher should ask you to recite the eight-digit number of 5."

Chen Xing nodded, he had no impression of this.

Haibara Ai glanced at him, "Is this a blind spot in knowledge?"

Chen Xing was a little embarrassed, "It seems."

Haibara Ai patted his legs in the corner like comforting.

Conan felt that he had some comfort, at least he could get some superiority from popular science. Especially, it was not surprising that he was the great illiterate illiterate.

Then, the noise of Mitsuhiko and Yuanta shattered his rare mood to relax.

"But are there eight figures in total?"

"How can I remember this!"
