Conan ran out of the library and went straight to the breeding hut outside the teaching building.
Here, the three little ones plus Haihara Ai are still cleaning the rabbit cage. Mitsuhiko and Genta go in to sweep up the rabbit droppings. Haihara Ai and Ayumi are outside watching the rabbits and not running around.
"Why are you back?"
Seeing Conan running back alone, Haihara Ai was a little surprised.
The black rabbit at her feet almost took the opportunity to slip away, but fortunately Ayumi's quick eyesight and quick hands caught the rabbit.
Conan leaned on his knees and took a few deep breaths, then stood up and walked straight to the rabbit cage.
"Misuhiko, Genta, did you find anything when you were cleaning?"
"thing?"
The two raised their heads and looked at Conan at the door in confusion, "What is it? There is only rabbit droppings here..."
Conan's eyebrows suddenly wrinkled, realizing that such a thing couldn't be on the ground, otherwise it would have been picked up long ago.
So, he raised his head and looked at the ceiling of the breeding hut.
At this time, Haihara Ai nervously walked up to Conan and asked softly into the latter's ear.
"Kudo, have you found it?"
"Um……"
Before Conan could finish his answer, his gaze was fixed on the corner of the ceiling of the breeding hut.
Because the breeding hut once leaked heavily, the school installed an additional ceiling under the original ceiling.
And in the gap between the double-layered ceilings, you can see a raised square box stuffed in there.
"Yantai, come and help me!"
"Ah? Oh..."
Conan summoned the tool man Yuantai directly under the square box, stepped on Yuantai's shoulders, and combined with the length of the broom, pulled the square box down from the gap.
Bang.
The box fell to the ground, making a sound of metal hitting the ground.
"Wow! What is this?"
Mitsuhiko bent down to pick up the box, but Haihara Ai rushed forward and held the box in his arms.
"Xiao Ai?"
Haibara Ai's unusually positive attitude also surprised Ayumi, who had usually accepted a cold personality.
But Hui Yuan Ai didn't care at all and picked up the box in his arms and looked at it carefully.
Conan also climbed off Genta's body at this time, put his hands in his pockets, and explained confidently: "This is the time capsule Miyano Akemi left 13 years ago."
"Eh-!"
The three little ones said in unison, looking at the box in surprise.
On the lid of the box, there is a piece of paper attached saying "This is the time capsule of the 19th graduating class, whoever finds it please give it to the teacher".
Hui Yuan Ai looked at the handwriting on it. Although it was still a little immature, she recognized it as her sister's handwriting at a glance.
Memories of his death flooded into his mind, and Hui Yuan Ai's hands trembled slightly, and his eyes couldn't stop feeling sore.
Seeing this, Conan smiled slightly and took the box into his hands.
He opened the lid and found a stack of thick envelopes inside.
Under the baptism of time, the envelope has turned yellow, and the children's names are written in crooked handwriting on it.
In order to take out Miyano Akemi's time capsule before the adults came back, Conan divided the envelope into four parts and asked the three little ones to help him find it.
"You just need to help find Miyano Akemi's envelope..."
"Miyano Akemi?"
"No problem, I'll cover it!"
The three little ones took their own pile of envelopes and began to rummage through them one by one.
With Conan included, each person only needs to view less than 10 messages.
And Haiyuan Ai stood beside him blankly, his heart pounding.
Her mind was a little confused now, and she was both looking forward to it and nervous at the same time.
What I look forward to is being able to have a conversation across time and space with my sister who has been separated by Yin and Yang.
I am nervous because I don’t know what my sister will say to me when I was a child.
What if my sister has some expectations for me, but my actions over the years have not responded to her expectations?
After all, my sister is such a kind person...
And he is just an executioner who researches murderous poisons.
Thinking of this, Haiyuan Ai couldn't help but lower his head and tightly grasped the hem of his woolen coat with both hands.
At this moment, Conan, who was squatting on the ground, suddenly spoke.
"It's okay..."
"Don't be nervous, trust me, she won't blame you."
Haiyuan Ai looked stunned and looked at Conan who was still checking the envelope.
The latter didn't even look at her, but casually explained her inner tangle.
But even though it was a careless comfort, Haiyuan Ai felt a warm current pouring into her heart.
The nervous little hands gradually loosened the hem of his clothes.
At this moment, Mitsuhiko, one of the three little ones, took the lead in checking the envelope he was assigned.
"I've checked, there's nothing there..."
"Me too, I didn't see the envelope signed 'Miyano Akemi'."
"Me too..."
The three of them looked at each other, then looked at Conan.
Conan also stared at them in surprise.
Because I had already checked the envelopes here, and because I was afraid of missing them, I checked them several times.
It turned out that there was no letter from Miyano Akemi inside.
"Did you really check it? Didn't you miss anything?"
"Or a typo?"
Conan asked quickly.
The three little ones looked a little dissatisfied, "Of course, if you don't believe it, come and take a look."
Conan reached out and took the envelopes from the three people and started counting them again.
But even if he counted it himself, and with Haihara Ai watching next to him, he still didn't find the envelope signed by "Miyano Akemi".
Conan put the envelope aside and checked the box again, but there was nothing missing inside.
All the envelopes from that year are here.
But there is no one like Miyano Akemi.
"how so……"
Conan stared at the box and envelope in shock.
It is clear from the oral descriptions of the trio of graduates that Miyano Akemi must have left her own time capsule and words to her sister Miyano Shiho.
But why...
At this moment, several figures walked out from the door of the teaching building. They were the trio of graduates, Kobayashi, and Rumi Wakasa.
Conan immediately retracted his thoughts, put the envelope into the box, and let Haibara Ai keep it temporarily.
At this time, Haiyuan Ai's expression was already a little dazed, and he mechanically took the box with both hands.
Conan also understood the loss and gap in her heart.
But because of this, he had to rely on reasoning to make a quick decision, and then find Miyano Akemi's time capsule. "If we can't find the time capsule, how about everyone recalling the contents?"
"Well, I have no choice but to do this..."
"But I'm a little embarrassed, after all, I'm telling so many people the messages I made when I was a child."
The trio of graduates walked to the breeding hut talking and laughing.
They came to express their gratitude to the young detective team who helped.
"Children, although I didn't find it, I still want to thank you for your help."
"Then you continue to clean up, we will go back to hold the class reunion first."
Murata Takumi smiled and waved goodbye, and Yanagi Machigaku and the doctor woman turned around and left.
But Conan put his hands in his pockets, raised the corners of his mouth, and stood there with a confident look on his face.
"Is it okay to just leave like this?"
"I don't even want the time capsule that holds important memories..."
After Conan finished speaking, the three graduates were stunned for a moment.
The three of them turned back at the same time and looked at Conan nervously, "Did you find the time capsule?!"
Conan smiled slightly and did not comment.
He turned his eyes to Yanagi Dingue and asked: "First of all, I want to ask, brother Yanagi Dingue, why do you keep hindering our search for the time capsule?"
As soon as these words came out, Yanagi Machi's tiger body trembled, and his upper body subconsciously leaned back.
"Where, where is it?"
"How am I hindering everyone?"
Two drops of nervous sweat flowed down Yanagi Tingyue's cheeks, and he defended himself, "Didn't I unlock a lot of secret codes? How come it's an obstacle?"
However, Conan replied directly with a childlike expression: "You are obviously hindering everyone, after all, you have prepared so many wrong answers..."
As he spoke, he took out his mobile phone from his pocket and showed the photos in the album to everyone.
"The first is the third code, 'Don't draw.' Because the school prohibits drawing on the rooftop, you wrote ぐ on the doorknob leading to the rooftop."
"But the same ぐ is written under the edge of the art room table."
"There is also the secret code for the health room. Although some students lied about feeling unwell and went to the health room to sleep, so they found it under the bed."
"But there is also a し on the back of the height measuring machine, because some students will secretly tiptoe during the physical examination and cheat on their height, right?"
"There is also the painting with the first code. I was the one who checked the painting before. There was nothing written on the wall behind the painting at that time."
"That is to say, Brother Yanagimachi, you secretly left false answers wherever you could associate them with the code."
"In the first action, you guessed that one of us would guess a certain answer in the next round of action, so you secretly arranged everything."
"Am I right? Brother Yanagi Machi?"
Although Conan always calls "brother" sweeter than anyone else, his sharp eyes seem to have seen through everything.
Yanagi Tingyue broke into a cold sweat, and looked at the stunned eyes of his two old classmates. In the end, he couldn't bear the pressure.
"Yes, it's me..."
"Yanagi-machi? Why did you do this?" the doctor asked in disbelief.
Yanagi Dingue lowered his head and began to reveal.
"Sorry, it's because I'm too scared..."
"The fire that broke out in the music room 14 years ago was actually caused by me sneaking into the school and playing with fireworks with the bad kids from the neighborhood."
"We were seen by Mingmei at that time, so I was very afraid that Mingmei would tell this matter..."
The expressions of Takumi Murata and the doctor woman were even more surprised.
The former stepped forward and asked: "Is this true? Yanagi Town?"
"Um……"
"On the day of the graduation ceremony, Mingmei came to me alone and asked me to muster up the courage. I guess she asked me to go to the police and surrender."
"I was so scared at the time that I didn't say anything."
"But I'm afraid Mingmei will write this matter in the time capsule and make it public."
"If a current firefighter is a former arsonist, it's not something that can be dismissed with a smile..."
As he spoke, Yanagi Dingue shed tears of regret.
The air was silent for a moment, then Murata Takumi walked up to Yanagimachi and put his palm on his shoulder.
"I understand you, so why don't I?"
"Actually, the painting in the principal's office that won the award was just because Mingmei didn't submit her better painting to the competition."
"I'm also worried about her writing this down in the time capsule..."
The doctor woman also stepped forward and said in a deep voice: "Me too."
"During the Chinese language test, I once copied Mingmei, who was sitting in the row in front of me. Because of this, Mingmei was called to the office together by the teacher."
"I'm also afraid of her..."
Seeing that the three of them had formed a victim alliance, as if Miyano Akemi was some kind of devil who took advantage of the weaknesses of her classmates, Conan suddenly interrupted the three of them.
"How could she write this!"
"She is the most popular and popular person in the class. How could she write such negative things in the message?"
Conan's eyes turned to Haihara Ai aside and motioned for her to take out the box.
As Haihara Ai brought the box hidden in his clothes in front of him, the three graduates suddenly looked startled.
They recognized it at a glance. This was the box that originally collected envelopes from everyone in the class.
"This is……!"
"Yes, this is your class's time capsule."
Conan handed the box to the three of them and said, "Actually, the code on that code paper comes from the keyboard that Miyano Akemi often encountered when she was a library committee member."
"As long as you rotate the computer keyboard 90° clockwise and write down the key positions required to type each code sentence, you can get the content of the code."
"There are five codes in total, and the final result is しいくこや, which is the breeding hut."
Conan didn't explain it sentence by sentence, because the three of them were rummaging through the box and didn't care about the solution to the code at all.
Only Teacher Xiao Lin stood beside him and pumped his fist excitedly, "That's it!"
"This secret code is so cleverly designed that even I, the library committee member, didn't think of it!"
At this time, the three of them thoroughly looked through the envelopes in the box, but still did not find what they were looking for.
"Strange, there doesn't seem to be Mingmei's envelope in it?"
"yes……"
When Conan saw this, he quickly spoke up. This was what he wanted to know most.
"Brother Murata, did you really see Miyano Akemi put the envelope inside?"
Takumi Murata nodded, "Yes, everyone's envelopes were put in in front of the podium one by one. There should be no omissions."
The doctor woman added: "But the teacher only gave Mingmei the job of hiding the time capsule."
Yanagi Dingue raised his head, "Did Mingmei take her envelope away at that time?"
Murata Takumi held the box in one hand and his chin in the other, murmuring: "It's possible..."
Conan, who was at a lower position, stared seriously at the facial expressions of the three of them, unable to tell which one of them was lying.
If they go by their guess, it is possible that Miyano Akemi removed her envelope.
After all, Miyano Akemi is a member of the organization. In order not to implicate her elementary school classmates who met her by chance, she can only try to cut off contact with everyone.
Maybe before deciding to leave the organization, he returned to school and collected his envelope in the box...
In Conan's mind, he could only think of this possibility.
