Conan: This repairman is not very knowledgeable

Chapter 213 This prisoner is very hardworking
"!" Ninagawa Ayako's eyes widened a bit.

Somewhat unexpectedly, he turned out to be the primary target of suspicion.

"Teacher, the success rate is still so high!" Lin Feng couldn't help but nodded and praised.

The other party first helped us rule out suicide, and now helps us rule out another one. So, the answer to who the culprit is is already out!
"Of course, hahaha!" Uncle Maoli laughed proudly.

If you want to hide it from me, Detective Mouri Kogoro, stop dreaming!
Oh, I am a sleeping detective.

"Ninagawa-san, who is in charge of selling drinks, is indeed the most likely person to add that ice cube." Hattori shook his head.

"However, she deliberately replaced the iced coffee with Coke without permission. No one would poison a drink that might be returned, right?"

Moreover, there was another person who ordered iced coffee like Mr. Urata. If the bet was wrong, he put poisonous ice cubes into someone else's cup. This was really stupid.

"..." Uncle Maoli thought about it and realized that this was indeed the case.

However, the repairman just said that he has a high success rate. I am a little confused as to why.

"So?" Officer Megure looked at the only one who had not been eliminated.

She was the only one left.

"That's right, the only person who poisoned Mr. Urata was Miss Kogami Mai who went to queue to buy a drink and got it with her own hands from the audience!"

Since Kidd had just helped pass a level, Conan was still in a cautious state and only dared to discuss it privately. Lin Feng was not very interested because of the problem with the transcript and because he already knew the answer to the puzzle.

So today is Hattori's special event, and it's finally his turn to show off his skills at Teitan High School.

The culprit has been pointed out, and all eyes are focused on Hongshang Wuyi, who is wearing a green hoodie and has short hair.

"Mai, Mai." Mitani Yota looked shocked. Looking at his familiar classmate and colleague, he couldn't help but take a step back.

"As for the timing of adding ice cubes, it's not difficult to guess. After you buy the drink, just pretend to be adding creamer syrup to the coffee at the counter and take the opportunity to put it in."

Hattori looked at Kogami Mai and said.

Of course, because of the variable existence of Ninagawa Ayako, the two cups of iced coffee were replaced with Coke. After putting in the ice cubes containing cyanide, the creamer and syrup could no longer be put in.

"Wait a minute, what if Urata finds something wrong with the drink and runs to return it?" Noda Yumei still wanted to defend her friend again.

"The reason why she returned to her seat when the performance started was because she didn't want this to happen." Hattori had already thought of this.

It can be said that from the moment you order the same drink, every step the other party takes has been planned in advance.

When the play started, the venue was pitch dark. It took a lot of time to go back and forth, and it was also very inconvenient to move around.

"But the ice cube infused with poison must have been made in advance, right?"

"How did she carry it around?" Officer Megure still had questions.

The other party is a human being, not a refrigerator. It’s not easy to carry a poisonous ice cube with you...

"Nothing is difficult in the world." Lin Feng threw the empty cup into the trash can and turned around to say.

Whether you can do it or not depends on how much effort you are willing to put into this matter.

"That's it!" Conan took out an object wrapped in a handkerchief from his pocket.

Inside the white handkerchief is a plastic wallet with a metal lock.

This kind of wallet is shaped like a shell and has better sealing performance. In most cases, it is used by women or children to store change.

"Conan-kun, where did you find this?" Officer Megure took the wallet and asked curiously.

"I saw it in the trash can when I was going to the toilet. Because the appearance was intact, it felt a bit strange that it was thrown away." "After I told Hattori-nii and the others, they asked me to pick it up. ." Conan said with a smile.

I can still do the small thing of picking up garbage. Even if I am a primary school student, I am also a primary school student who loves reasoning...

"As long as you put ice cubes that have been prepared in advance and injected with poison into this wallet, and then put in a small piece of dry ice, the problem of ice cube preservation will be solved."

Hattori opened his mouth to explain.

As for how to deal with wallets and dry ice, Hongshang Wuyi actually gave the answer a long time ago.

After the other party bought the drinks, she gave them to Mr. Mitani for distribution. She went to the bathroom, threw the small piece of dry ice into the toilet and flushed it away, and threw her wallet into the trash can.

"Brother Takagi, take it to the forensic personnel." Officer Megure handed the wallet to Takagi.

"Although he is only a high school student, he really looks like a detective."

"However, you haven't forgotten. Dr. Urata and I both ordered iced coffee, and we handed both cups of coffee to Mitani. I don't know which cup of coffee he would leave for me."

"How do you poison someone in this situation?"

"Speaking of which, if you think I would bet on the 50% chance of success, then Ayako, who is responsible for making the drinks, might also do the same, right?"

Kogami Mai looked at the high school detective with a strong Kansai accent and defended herself.

"No, as long as you are willing to take a little risk, the chance is 100%." ​​Hattori said with a smile.

Really tough-talking.

"The two drinks, including the one she drank, were all poisoned." When Lin Feng said this, he couldn't help but glance at Miss Hongshang.

If you are desperate enough, no matter how fast you drink the drink, if there is something wrong with the ice cubes you make, you will probably be sent away too.

"Both glasses are in it?" Officer Megure asked in shock.

"That's right, in order not to attract attention, she couldn't leave her seat to deal with the poisonous ice cubes in her cup, so she could only hide it somewhere on her body in a dim environment." Hattori took out a He picked up a yellow ten-yuan coin and said with a smile.

Next, we just need to put this copper coin there, and everything will be revealed!
The redox reaction between potassium cyanate and copper will cause the surface of copper to become shiny.

Officer Mumu stared at Hongshang Wuyi, preparing to send someone to check.

Hongshang Wuyi's tense expression suddenly relaxed. With a wry smile on his face, he asked, "When did you start doubting me?"

"The moment you took out the creamer and syrup from your trouser pocket, you already showed your flaws. The rain that followed further confirmed our idea."

It was a bit strange that the other party didn't explain the ice coffee and Coke to the police immediately.

Moreover, when watching the play, the venue was very dark. Unless you put the cup in front of your eyes, it would be difficult for ordinary people to tell whether it was iced coffee or cola. Creamer and syrup had already been poured in all at once.

Of course, if the other party opens the cup and confirms it in advance for some reason, then there will be no doubt at all.

"Is there anything wrong with that rain?" Uncle Maori thought hard and didn't notice any details.

"Haha, it was clearly raining outside, but when we took Officer Takagi to the car, I didn't put on my hat and kept running in the rain."

Kogami Mai took off the green hoodie she was wearing and handed it to Officer Megure.

That's right, after quickly finishing the drink, she quietly put the ice cubes into the hat behind her in the dark.

Although potassium cyanate is difficult to dissolve in cold water, it dissolves when it comes into contact with water. If the mask was put on her head and in contact with the skin, she would be carried away soon...
