I'm making soy sauce in the detective world

"By the way, Hattori, do you have a ten yuan coin on you."

Shinichi’s words made Hattori a little bit awkward: "Yes, what do you want coins for?"

Suddenly, Hattori thought of something. After all, he is also a high school student detective of the same name, and his head is definitely spiritual, and he immediately understood what Shinichi meant.

Hattori took out the coin and handed it to Shinichi.

Officer Megome asked, "Brother Kudo, I am very happy to see you come back, but the drink cups of the deceased and the other three have not been found to contain any traces of poison."

"Don't worry, Officer Mumu, the murderer is taking advantage of the victim's trivial habit, and now the murderer should still have a piece of evidence in his hands."

Shinichi is very confident, he has figured out the whole thing in his mind.

Officer Mumu still didn't figure it out. According to his thoughts, no poison was detected in the cup, and the victim drank all the drinks, which looked like suicide by taking poison.

Shinichi shook his head: "Indeed, you might think so at first glance, but you only need to use one thing, that is, use ice!"

"ice?"

"Potassium cyanate is difficult to dissolve in ice water. Just inject potassium cyanate into the center of the ice cube, fill in the hole, and put it in Mr. Urata's cup together with other ice cubes, so that Mr. Urada can be made before it melts. Drink most of the drinks."

But even so, the dissolved poison should still be left in the cup, which is why Officer Mumu is puzzled.

"Mr. Urada's lid is opened, right? Do you know why it is opened?"

Uncle Maori didn't think about it, and he said directly: "Maybe it was because Mr. Urada was in pain after taking poison, so..."

Before finishing talking, Officer Mumu directly interrupted Uncle Maori's words: "Nonsense, if that were the case, the cup would have been broken!"

Shinichi continued to explain: "After drinking this beverage with ice cubes, there is only one reason to open the lid, that is, Mr. Urada ate the ice cubes instead of drinking the poison. Eat the ice cubes, of course you will not detect any residue."

As he said, Shinichi pointed to a corner of the crowd and curled his lips: "It's the same as Guangyou's actions now."

Everyone looked in the direction of Xin Yizhi, and saw that Guangyou was holding a cup of drink, and was looking up and swallowing the ice in the cup, making the sound of the ice being crushed.

At this time, Guangyou had just finished a glass of iced fat house happy juice, and he was in a good mood. A glass of iced drink on a hot day, the taste, one sentence describes "too cool, heart flying."

He is also used to eating the remaining ice cubes, so as not to waste it, and when he bit the ice cube, he felt that someone was watching him, and not one, but many.

He looked back at the crowd, pointed at Shinichi in the crowd, and said vaguely: "Look at me, look at him, just have a drink."

A black line appeared on everyone's heads, and then Takagi came out to make a round of rounds: "Yes! Officer Megome, don't you often eat the remaining ice cubes!"

Officer Megome nodded: "Indeed, as long as you know that Urada has this habit, you can easily kill him with poison."

This habit is also a habit that many people have. It is not uncommon. Most people would never think that someone would use this to kill. It is simple and hidden.

Uncle Maori didn't have much interest in how to kill people. He squinted his eyes and asked, "According to you, who is the person who added poison to the ice?"

Mitani and Noda, who were only responsible for delivering drinks, were naturally excluded. There was no time to commit crimes. On the contrary, Ninagawa, who sold drinks, was very suspicious. After all, it was the ice she added. She was suspected. This is also very normal.

However, Ninagawa deliberately changed the iced coffee ordered by the deceased Uradahara to Coke without authorization. This means that the drink may be returned for replacement at any time. This is also very normal, but this makes Ninagawa’s suspicion much lower. The murderer would generally not do uncertain stupid actions, and another person ordered iced coffee at the time, so it was easy to accidentally be injured. The murderer was not a murderous maniac. The murderer would not do this kind of action.

According to the new method of exclusion, after everyone has eliminated the suspicion of these people, the only people who have been in contact with the deceased and known are left to buy drinks and bring them to the audience. Wuyi still has a suspicion alone.

After eliminating all the impossible things, what is left, even how unreasonable and impossible, must be the truth. Even if Xin Yi thinks about it again and again, he will never think of another person having a chance to poison it.

As Hongshang Wuyi’s friends, Noda and Mitani naturally did not believe that their friends would actually kill people. They subconsciously defended Hongshang Wuyi and said: "According to your statement, Wuyi pretended to add creamer and syrup. Then he poisoned it quietly, but didn't he find unused creamer and syrup on Urada's pocket?"

At this time, Guangyou had already chewed the ice cubes, and the coolness in his mouth made him suck and breathe. The refreshment instantly relaxed his mind. He said beside everyone: "But, Mr. Urada’s is not Coke? Have you ever seen Coke with creamer and syrup? Mr. Urada probably wouldn't drink it after adding it, right?"

Feizhai Happy Water plus creamer and syrup are all heretics, which completely destroy the taste of Happy Water itself!

Xin nodded: "Yes, if it is added, Mr. Urata will not drink it very much. Besides, Miss Hongkami will bring the drink to you before the show starts, so as to prevent Mr. Urata from changing drinks. Because turning off the lights during the performance is still very troublesome if you want to go out. Unless you particularly hate Coke, Mr. Urada shouldn't bother to change drinks."

Officer Mumu asked a question he hadn't figured out yet: "How did she carry the poisonous ice on her body and walk around at will?"

It was sunny today, although the temperature was not too high, but in a crowded venue, it can be said to be very hot, and it is precisely because of the heat that drinks are specially sold in the venue.

"I just went out to look for it," Shinichi took out a purse from his arms and said, "I found this purse in the trash can in front of the bathroom. Just put the ice cubes in and put a small piece in it. Dry ice can keep the ice cubes from melting for a long time."

Hong Shang Maiyi lowered his head and said with a smile: "As expected of Shinichi Kudo, but you know, Mr. Urada and I both ordered iced coffee. What's more, I handed all the drinks to Mitani. Give it to everyone, how do I know which drink he wants?"

This is reasonable, but Shinichi disagrees. He said, "Because you have poisoned both of your drinks."

As soon as these words came out, everyone felt like turbulent waves in their hearts. This news was so shocking that in order to kill someone, they even put themselves in the same dangerous situation.

But this is also suspicious. Hongshang Wuyi also drank the drink. Even if she drank the drink before it melted, the remaining ice cubes would either be detected or poured out, which is even more suspicious.

Shinichi has a third choice. He explained to everyone: "What if Miss Hong Shang put ice cubes in her mouth like Mr. Urada?"

Another big wave directly chilled everyone's backs, and she would die if she was not careful.

With that said, Shinichi took out the ten-yuan coin that Hattori had just given from his arms, flicked his finger, the coin rotated in the air and drew an arc, directly falling into the hood of Hongshang's dance clothes.

Shinichi explained: "Although it is said to be more dangerous, as long as you make sure that the poison is in the middle of the ice cubes, be careful and you will be fine."

Officer Mumu asked, "Then how can you be sure that she is hidden in the cap?"

"Look, the coins are still shiny, right." At this time, Hattori has quietly arrived behind Hongshangwu's clothes, took out the coins from the hood and showed them to everyone, "This is the production of potassium cyanate. The best proof of redox phenomenon."

The proof is like a mountain!Hongshang Wuyi's eyes moved slightly and finally admitted!
