"Ahem." Memu suppressed the upturned corners of his mouth and said seriously, "Did Mr. Kuroki notice anything wrong before this?"
Kuroki Ren was actually quite surprised why they didn't ask the three people related to the deceased first but instead came to him and asked him this and that, but he still replied: "There is nothing wrong. He made a loud noise not long after drinking the drink." I heard the strange noise more clearly when I was closer, and when I went to see him, he put his hands on his neck as if he wanted to say something, and then he fell down."
"I just helped him fall down and asked the scene to turn on the lights. At that time, I was not sure he was dead."
Asai Narumi took over: "It was the aorta that I went up to touch and found that it was no longer beating."
Megure still had some impressions of Asai Narumi, remembering that he was a doctor, and approved of him stepping forward to diagnose emergencies.
If it wasn't cyanide, a poison that would kill someone after a certain dose of ingestion, but someone at the scene had a heart attack or some other accident, Asai Narumi might have saved a life by coming forward for consultation as soon as possible.
But it was impossible for him to examine the body again. There was a police coroner at the scene. After the forensic personnel collected evidence from the scene, the body was transported back to the station for autopsy.
"Did Mr. Urata buy this drink himself?"
While waiting for the specific results to come out, Memu began to ask the deceased what he had done before.
"No, I bought the drinks together." Mai Kogami, who was sitting on the outermost side, replied, "After buying the drinks, I gave all four drinks to Yota and went to the bathroom before the show started. "
"Then I handed the drink to Yumei, who then gave the drink to Gengping."
Yota Mitani, who was sitting second next to him, answered.
"What are you talking about!" Noda Yumei refuted the slightly pointed words, "It was you who helped Gengping choose the iced coffee."
"Iced coffee?" Several people present repeated it at the same time.
Kuroki Jin and Asai Narimi looked at each other, and then looked at Hattori Heiji who also noticed something was wrong.
"What's wrong with the iced coffee?" Noda Yumei was startled by the three people's reactions, thinking she had said something wrong.
"Mr. Urata's drink should be iced Coke." Seeing that Kuroki Jin and Asai Narimi didn't mean to answer, Hattori Heiji explained. He had just taken a peek when he stopped Asai Narumi from touching the evidence at the scene.
Even though the drink was finished, the lingering smell was still there, especially for a strong-smelling drink like coffee. But there was no coffee smell left in the cup that fell to the ground.
"The store must have made a mistake. My cup was also iced Coke." Wuyi Hongshang said in a low voice, "But when I found out, the show had already started. It was too troublesome to go back to change, so I just drank it."
"And there's one more thing," Mai Kogami continued, "At that time, Kohei originally wanted to come over and get a drink with me, but then he suddenly turned pale and said he wanted to go back to his seat."
"I guess it's because he saw me."
Everyone looked over and saw the person coming - a girl wearing a Didan school uniform and an apron stood behind.
"It's Caiko. Yes, you are also a student of this school."
The visitor introduced himself as Ninagawa Ayako, the daughter of the director of the Rice Flower General Hospital where Urata Kohei and others worked.
Kuroki Ren raised his eyes slightly and then lowered them. He looked down at the original position of the body that had been carried away, and slightly raised his lips.
He had roughly figured out the murderer's modus operandi, but he lacked some key evidence, so he remained silent and waited for the prisoner to reveal himself.
When a person is very concerned about the existence of something, he will always unconsciously look at its location. With Kuroki Jin's observation skills, he was confident that he could detect where the target was worried.
"Now the four suspects are all here." Hattori Heiji, who was leaning against the wall and had completely wiped off the white powder on his face, laughed and glanced at the four people in turn.
"Hey, you mean the murderer is among us?" Noda Yumei, who had a slightly hot temper, immediately retorted, "But except for the last time I handed the drink to Kohei, I never touched that cup again!"
"And the lights were still on at the time. If I did anything, everyone could see it."
Kuroki Ren's eyes lit up, and he quickly interjected and asked: "When did the lights turn off?"
"Uh... just after dividing the drinks." Noda Yumei said.
"Did Miss Kogami come back at that time?" Kuroki Ren asked the second question.
"No." Yota Mitani replied first, "I remember that Mai came back in the dark after the lights were completely dimmed."
"When did Ms. Hongshang realize that the drink was not iced coffee but iced Coke?"
Kuroki Jin's third question almost made the person in question break into a cold sweat.
"When...when I took the first sip." She replied with some uncertainty, "By the way..." She wanted to change the topic.
"If you noticed it at the first mouthful," Kuroki Jin didn't give her a chance, "then why didn't you put creamer and syrup in your cup?"
Hongshang Wuyi clenched her fists slightly, hid them behind her back, and replied with a slightly stiff smile: "Then maybe I found it when I opened the lid of the cup to put the creamer in."
"This gentleman will not suspect that I am the murderer just because I did not add condiments to the iced coffee."
"Of course not, I'm just talking." Kuroki Jin showed a warm smile, and just when Kogami Mai breathed a sigh of relief, he continued: "Police department, search you."
"It's not about searching the items on the body, it's about looking for places on someone's body that can produce redox reactions."
Mu Mu was still a little confused and subconsciously asked why.
"Mr. Urata finished the drink early and started chewing the ice cubes in it." Kuroki Ren glanced at Kogami Mai, who had turned pale, paused and continued: "I'm sitting next to him, naturally. You could hear the sound. He was poisoned and died when he was halfway through eating the ice cube."
"This shows that the poison was originally hidden in the ice cubes, and in order for Mr. Urata to get the poisoned drink, Ms. Kogami naturally poisoned both cups."
"If the forensic report is correct, there will be no poison residue in the two cups. This is because one ate the ice cubes before the ice melted, and the other took out the ice cubes and put them on his body."
"Then whoever has a redox reaction in his body is undoubtedly the murderer. But at the moment, I don't know exactly where Miss Hongshang hid the poison..."
As soon as he finished speaking, a strange voice picked up his words.
"In the hood."
The knight in black who had been standing next to Mao Lilan and refused to take off his mask took out a ten-yuan coin from somewhere, put it into the hat of Hongshang Wuyi who was standing in front of him, and took it out again The coin came out sparkling.
The ten-dollar coin is made of bronze, and a chemical reaction with potassium cyanide makes the surface of the coin shiny.
And the coin that the black knight took out was exactly like this.
