At this point of the case analysis, the method of committing the crime and the cause of death have become clear.

Kogoro Maori looked at Kudo Shinichi with some frustration, "Who do you think this person who added poison to the ice cube?"

Kudo Shinichi looked at the nervous suspects and said, "It is impossible for Mr. Mitani and Miss Noda who are only responsible for delivering the drink cups. As for Ayako Ninagawa who is responsible for selling drinks, it is very likely that she will add ice cubes.

But she arbitrarily changed the iced coffee that Mr. Putian originally ordered for Coke, and she would never have done a foolish move to drug it in a drink that could be returned.

Besides, there was another person who ordered the same iced coffee as Mr. Putian at that time. This way, the target of the poisoning could not be determined, and the risk of failure was too great."

Officer Meguru looked at someone, "So, the murderer who poisoned him is..."

"That's right, the person who poisoned Mr. Kamata was Miss Hongsaka who went to buy drinks and even got it to the audience!" Kudo Shinichi confirmed.

When everyone saw this, Hong Shangwuyi tightened her face.

Kudo Shinichi said: "After you buy drinks for everyone, just pretend to add creamer and syrup on the counter of the beverage stall, you can add ice mixed with poison."

"But Maiyi didn't add creamer or syrup, either." Noda Meimei raised questions for her good friend.

"Yes, haven't you found unused creamer and syrup in Kamata's pocket?" Mr. Mitani also questioned.

Kudo said calmly: "That's because after she added the ice cubes mixed with poison, she found that the drink inside was Coke. If she added those, Mr. Kamata might not have drunk it at all.

She would take the drinks to you before the drama begins, in order not to want the drinks to be returned. Even if she finds that the drinks are wrong, the lights in the gymnasium dim, and it will take a lot of time to change the drinks and go back and forth."

Officer Megumi asked in confusion: "But how did she carry the ice cube with poison on her body and walk around?"

"I found this in the trash can in front of the bathroom." Kudo Shinichi took out a wallet from his pocket. "This is a plastic metal shrink-mouthed wallet."

Haibara Ai, not far from him, walked away a few steps away, and Chen Xing also felt that being a detective was too difficult.

Hattori Heiji looked at Kudo Shinichi with admiration and disgust, thinking in his heart that he was truly a high school detective who was as famous as him.

"Well... take it for identification immediately." Officer Megumi skillfully ordered Takagi Sora.

"Just put toxic ice in this wallet and a very small piece of dry ice, the ice can be kept from melting for a long time."

Kudo Shinichi looked at Hongsaka Mai and smiled confidently, "So, after you handed the drink mixed with poison to Mr. Mitani with other drinks, you went to the bathroom, threw the dry ice into the toilet and flushed it off, and then threw the wallet into the trash can. I was right?"

Mr. Mitani said blankly: "Miyi, did you really do it?"

Hongshang Wuyi was silent for a moment and smiled in a low voice, "Kudo Shinichi is indeed well-known, and he does look like a famous detective."

"But you haven't forgotten?" she said: "Dr. Kamata and I ordered iced coffee, and gave all the drinks to Migu to everyone. I don't know which iced coffee he would give to Dr. Kamata, so how could he poison it? Then, if I would put success or failure on a bet with only 50% chance, then Ayako would be possible."

"No, the chance is 100%," Kudo Shinichi said: "That's because you added pounds of toxic ice to those two iced coffees."

"What? How is this possible?" Officer Meguchi said in surprise: "She obviously drank all the things in her own drink."

"As long as you finish the drink as soon as possible before the ice melts, there will be no problem." Kudo Shin-chi said with a brow raised.

"But no poison reaction was detected in her drink cup." Officer Meguru asked: "If you want to avoid being suspicious and forcefully pour the ice cubes to the place, it will cause suspicion from the audience around you."

"What if she pretended to bite the ice cube after drinking it and put the toxic ice cubes into her mouth? In this way, just spit the ice cubes into her hands afterwards and secretly hide it."

After saying that, Shinichi Kudo threw up the coin in his hand, and during this period, his best partner Hattori Heiji had already made moves.

The coin flipped in the air and suddenly fell into the top and hat of Hongsaka Maiyu. Over there, Hattori Heiji looked "That's right" and held the edge of the hood with one hand.

The tacit cooperation between the two is more outstanding than this reasoning.

"But, did she really hide the poison in her hood?" Officer Megu said hesitantly.

"It's absolutely impossible." Hattori Heiji took out the previous coins with a handkerchief and held them for everyone to show them. "After picking up this ten-yuan coin, it will still shine."

Chen Xing was a little curious. Ai Haibara looked at him and said softly: "This is a redox phenomenon."

"That's right, that's it." Hattori Heiji nodded, but he was still a little suspicious. Since the person in front of him was Kudo, who is Conan now?

"..." Chen Xing.

Looking at the sudden realization of everyone, he felt a little frustrated because he had no idea what redox was!

"How did you know she was hiding in her hood?" Takagi Shiro said in confusion.

"This is because..." Kudo Shinichi was about to speak, but was interrupted by a voice, "It's because it's raining outside."

Hongshang Wuyi said, "It's raining outside. When we took Officer Takagi to find Dr. Kamata's car just now, I didn't pull up my hood."

"Yes, I started to doubt it from that time." Kudo Shin nodded.

"It's true that I poisoned Dr. Kamata because his behavior was not qualified to be a doctor at all." Hongshang Wuyi said coldly.

...

Whether it is love and hate or the emergence of a certain idea, it requires reasons.

The motive for Hongshang Wuyi's murder was because Dr. Kamata was about to publish a paper, and there was a case that was enough to overturn his theory, and the patient was staying in their hospital at that time.

Unexpectedly, the patient's condition suddenly worsened and he died. The reason was that Dr. Kamata prescribed the wrong medicine, which led to the rapid deterioration of the condition in order to maintain his vulnerable medical theory.

"The reason why I know is that he was rejected last week when he proposed to Aiko. He heard him talk about it when he was drinking." Hongshang Wuyi said lightly: "He said that he, who can freely decide life and death, was actually tricked by a girl who is 10 years younger than him. This world is really a cause and effect."

"Freely determines a person's life and death?" Kogoro Mouri said angrily: "It's a bastard!"

"So, I'll be here to treat his karma." Hongshang Wuyi smiled.

Is retribution? Chen Xing's eyes lowered.

"Detective, you are so lucky." Hongshang Wuyi said: "If there was no such rain, you wouldn't have found any evidence to prove that I was the murderer, right?"

"You are wrong. Even if you don't find any problem with your hood, I plan to ask the police to identify your clothes." Kudo Shinichi said: "Because from the point of keeping creamer and syrup, I have already determined that the murderer is you."

"What?" Hongshang Wuyi was stunned.

"Because you said that when you came back from the bathroom, the show had already started, right?" Kudo Shinichi said: "The drama began to take place, and the gymnasium was pitch black. Even if you opened the lid, you couldn't tell whether it was iced coffee or coke. So I'm sure that you had opened the lid before you knew that the drink inside was incorrect."

"So that's how it is." Hongshang Wuyi whispered.

...

"I found that you have become the little assistant of the big detective today." Touyama and Ye quipped.

"There's no way, this is Tokyo, of course I can't steal Kudo's limelight." Hattori shrugged and hit Chiyuki with his elbow, "You said yes, earth-shaking? We are the iron triangle."

Chen was defeated by him.
