How to develop the heroine Ke Xue

"Do you still want to quibble? Your motive for killing is very obvious." Officer Megure disagreed and continued.

"Please, officer, don't accuse people casually," Caiko said angrily.

"Well, Officer Megure, I don't think Ayako is the murderer."

Seeing this, Qin Xuan's mouth twitched and he had to stand up.

"Oops, I almost forgot that Qin Xuan is here! Qin Xuan, what do you think?"

The Mumu Police Department suddenly remembered that Qin Xuan's reasoning ability was no less than that of a detective. With Qin Xuan here, there was no need to count on Kudo Shinichi.

88. The average IQ of the Metropolitan Police detectives is no more than 90

"Officer Mu Mu, Cai Zi does have a motive for killing, but there is no evidence to prove that Cai Zi is the murderer." Qin Xuan explained.

"Take him back and interrogate him severely. There will be evidence." Mumu Police Department said disapprovingly.

"You fat policeman, you are so unreasonable." Ayako was very angry and wanted to punch the Megure Police Department twice. "My so-called motive for murder does not exist!"

"How do you say this?" Officer Mu Mu looked over doubtfully.

"Because as early as half a month ago, due to my strong insistence, I finally canceled the engagement as I wished, so your assumption does not exist at all!" Caiko said firmly.

"Uh-then why didn't you tell me earlier?" Officer Memu's mouth twitched, feeling quite embarrassed for a moment.

Seeing this, Qin Xuan was unable to complain. The IQ of normal people is 90-110, and the average IQ of the Metropolitan Police Department detectives definitely does not exceed 90.

"In this case, let's take the four of their drinks and creamer syrup for testing first, and wait for the forensic results to come out." Officer Megure coughed lightly and said to the police officer beside him in order to cover up his embarrassment.

"What did you remember?" Sato on the side continued to ask the suspect.

"Actually, we came together in Putian Gengping's car today. We all felt that something was wrong with his expression. He kept looking for something in the car," Noda Yumei explained softly.

"Then can you please take me to check his car to see if there are any missing clues." Sato said quickly.

"Of course, I'll take you there," Hongshang Wuyi stood up.

"Hey, it's so unlucky. First there was a strange murder and our performance was stopped midway. Now God has no mercy and it's raining. I don't know how long we will stay here. The romantic and warm atmosphere is gone. ”

Yuanzi leaned on Qin Xuan's shoulder and felt very disappointed.

"It has nothing to do with us anyway, just wait quietly."

Xiaolan disagreed and leaned on Qin Xuan's other shoulder with a sweet smile. She already regarded herself as Qin Xuan's real girlfriend, not a temporary fake girlfriend.

"After the rain, it will be sunny." Qin Xuan couldn't help but smile.

While Qin Xuan was chatting with the two little girls, Sato came back with Yumei and Mai to report to Officer Megure.

"How are you doing? What did you find?" Officer Megure asked.

"We found this in the deceased's locker." Sato took out a small bottle, which she had packed in an evidence bag.

"what is this?"

"I suspect it is a container used to hold potassium cyanide. I need to trouble my colleagues in the forensic department." Sato said softly.

"Well, fortunately, I just received a call from the forensic team, saying that there were no traces of toxic substances added to the drink cups of the four of them." Officer Megure nodded.

"In that case..." Sato frowned. There was no toxic substance, so the possibility of poisoning the drink was ruled out. Then it was necessary to re-investigate the direction of the investigation.

"I think the case can be settled by suicide." Officer Megure said without thinking.

"Suicide?" Sato frowned, feeling that it was too arbitrary, but she couldn't provide any evidence to refute it.

"The love that the deceased pursued so hard ended miserably in the end. Being dumped by a girl ten years younger than him caused great irritation to him. He might have lost his temper and committed suicide in front of his ex-fiancée. This is also the case. It’s very common, isn’t it?” Officer Megure said confidently.

Hearing this, Sato didn't say much, which made sense.Moreover, there is currently no evidence pointing to homicide.

"This is definitely not a suicide, and it is a simple homicide case!" At this moment, Kudo Shinichi, who disappeared for a while, came back again.

Of course, Kudo Shinichi is pretending to be Yukiko, who is playing double act with Edogawa Conan behind her.

"Brother Kudo, what evidence do you have to prove that the victim was killed by him?" Officer Megure was very cautious about Kudo Shinichi's words.

"The deceased was murdered to death. It all happened in front of a dark stage, right under my nose. The murderer only took advantage of his trivial habits." Kudo Shinichi said, accompanying With strong self-confidence.

"However, no toxic substances were found in the deceased's drink cup or the drinks of the other three people." Officer Megure said involuntarily.

"At first glance, this does make people doubt that the deceased committed suicide by taking poison, but as long as something is used, the murder can be easily completed." Kudo Shinichi raised his lips slightly.

"What?" Officer Megure asked blankly.

"That's the initial criminal method, just use ice." Kudo Shinichi said softly.

Kudo Shinichi left halfway because he wanted to find the truth. Now he already knows the ins and outs of the incident.

"Ice? Why is it ice, Qin Xuan?" Yuanzi raised her little head and was very confused. In fact, she was still interested in reasoning.

"It's very simple. Potassium cyanide is a quick-acting drug. If the drink is poisonous, he should die immediately. The deceased did not have the accident after drinking the drink, but it would be different if there was ice." Qin Xuan glanced at her and said softly.

"Why?" Yuanzi blinked his big eyes and was very curious.

"Potassium cyanide is extremely difficult to dissolve in ice. You only need to dig a small hole in the ice, inject potassium cyanide into the center of the ice, and then use small ice cubes to cover it with other ice cubes. Together, they can be put into the deceased's drink so that the deceased can drink most of the drink before the poison is dissolved." Qin Xuan said with a smile.

"But even so, there should be some residue in the cup," Sonoko said in confusion.

"You noticed that the deceased's drink bottle cap was open, right? Do you know why?" Qin Xuan was not in a hurry to explain. Seeing that Yuanzi was interested, he slowly taught her to analyze the problem step by step.

"I guess she must have opened the lid because she was in pain after drinking the poison and couldn't control the strength." Xiaolan was the first to answer.

"Fool, if you do that, don't mention the lid, the whole cup will be crushed." Qin Xuan continued to explain.

"I understand, there is only one reason why the lid of the cup is opened after drinking this drink with ice." At this time, Sonoko suddenly exclaimed.

"Really?" Xiaolan cast a suspicious look.

"Some people have the habit of eating ice cubes, so they will break the lid of the cup." Sonoko chuckled.

"That is to say, the deceased did not drink the poison, but ate it." Xiao Lan also instantly realized that as long as she knew that the deceased had this little habit, she could indeed murder him with poison.

"Lan, you are so smart," Yuanzi joked.

"Then who is this person who poisoned the ice?" Just when Qin Xuan finished explaining to Xiaolan and Sonoko, Kudo Shinichi on the other side also explained to Officer Megure.

"Mr. Mitani and Ms. Noda who are only responsible for passing the drink cups are impossible. As for Ayako-san who sells drinks, it is very likely that she will add ice cubes..."

"I knew it was her, what excuses do you have now!" Before Kudo Shinichi could finish his words, he was interrupted by Officer Megure, pointing at Ayako and yelling.

"I, I didn't." Seeing that it was coming back to herself, Cai Zi felt so bitter in her heart that she was wronged, why did she like to bully her?

"Officer Megure, don't worry, I haven't finished speaking yet." Kudo Shinichi twitched the corner of his mouth.

"Shinichi, please finish your sentence once and for all." Officer Megure suspected that Kudo Shinichi deliberately made him look embarrassed.

"Although the suspicion is high, she replaced the deceased's iced coffee with Coke without authorization. She would never have made such a stupid move as poisoning the same drink that might have been returned." As mentioned before, many geniuses All have one common characteristic.

"

That's right, the only person who can be poisoned is you - Ms. Mai Hongshang! "Kudo Shinichi turned around and pointed with his right hand, with an unquestionable tone. His powerful and confident aura was intimidating!

"Wu Yi..." Everyone was stunned for a moment.

"After you buy drinks for everyone, just pretend to add syrup on the counter of the drink stand, and then you can add ice cubes with poison." Kudo Shinichi said proudly.Yukiko performed with Conan behind her, and her expressions were very spot on. She was worthy of being a big star in the past.

"Wait a minute. Don't forget that Mai didn't add any syrup herself. Didn't Kamata Kohei also find unused syrup in his pocket?"

Before Kogami Mai could speak, Noda Yumei stood up to defend her.

"That's because she discovered after adding ice cubes that it turned out to be Coke. If she had added those things, the deceased might not drink it at all," Kudo Shin explained calmly and calmly without any rush.

"Kudo Shinichi, I ordered the same drink as Kamata Kohei, and I can't guarantee that I will get that drink. Do you think I will put myself in danger?" Kogami Mai is calm and not afraid at all. Kudo Shinichi.

"No, of course not, but you can guarantee that you will not be poisoned," Kudo Shinichi said softly.

"Oh, so sure?" Hongshang Wuyi was very surprised.

"Of course, you only need to poison both drinks. As for why you are okay, it is actually very simple. You just need to finish the drink before the ice cubes melt." As he said that, Kudo Shinichi's confidence returned. He came back, and he didn't believe that he would make a mistake again this time.

"But even if this is the case, there is no reaction of any poison in my drink cup?" Although the other party explained almost all of her criminal process, Hongshang Wuyi did not panic at all.

"But what if you are like the deceased, pretending to chew ice cubes after drinking the drink, and put the poisonous ice cubes into your mouth? Although it is a bit risky, just spit the ice cubes into the palm of your hand before the ice cubes melt. Just hide it secretly, am I right?" Kudo Shinichi explained softly.

"If it's really me who poisoned me, then how do I carry the ice cubes around without melting?" Hongshang Wuyi's lips raised slightly, as if a famous detective had nothing to do with me.

"Because the color of coffee and cola is difficult to distinguish; as for why the ice cubes did not melt, it must be that you used some kind of special container."

Kudo Shinichi explained.

"Interesting, it is true that the colors of coffee and cola are similar, but there is nothing wrong with my nose. Or do you think coffee and cola taste the same? Where is the container you mentioned?"

Kudo Shinichi seemed to expect that Mai would say this, and took out a plastic peach pink metal shrink wallet and placed it in front of Mai.

Kudo Shinichi said: "As long as you put ice cubes mixed with poison and a small piece of dry ice into this shrink wallet, you can keep the ice cubes for a long time without melting. Therefore, Ms. Mai Kogami, After you handed the poisoned drink to Mr. Mitani along with the other drinks, you went to the bathroom, flushed the dry ice into the toilet, and then threw the wallet into the trash. How about that? I was right. Bar?"

The sarcasm on Hongshang Wuyi's lips became even more intense: "You just dug out an unknown person's wallet from the trash can and said it was mine. Do you want to prove that I am the murderer?"

Edogawa Conan became nervous, and Yukiko, who was pretending to be Kudo Shinichi, was no longer so confident.

Yukiko began to wonder if Conan had made a mistake, and the victim might have committed suicide.

Although Yukiko was suspicious of Conan, she continued the performance according to the preview.

89. Thousands of arrows pierced the heart, and Conan was hit one after another.

Yukiko took out a ten-yuan coin from her pocket, and then used Kudo Shinichi's tone to play a double act with Conan behind her.

"This is a ten-yuan coin. It will sparkle when it encounters potassium cyanate. That is the best proof that an oxidation-reduction reaction occurs. Although I did not find other evidence, I have this conclusive evidence. , it’s enough.”

"So you don't mean to say that I hid poisonous ice cubes on my body, such as my hoodie?" Hongshang Wuyi took the initiative to say it.

"Are you ready to surrender now?" Kudo Shinichi asked.

"The reason why you suspect that the ice cubes are hidden in my hoodie is because you just saw me accompanying Officer Sato and the others when it was raining and I was not wearing a hat without an umbrella, right?" Hong Shang Wuyi couldn't help but say.

"Is there something wrong?" Kudou Shinichi frowned, he was really sure after seeing this scene.

"Tsk tsk, do you think you know me very well?" Hongshang Wuyi asked back.

"I don't understand." Kudo Shin said immediately. It was the first time they met. How could they understand each other?

"Then why do you think I have to wear a hat when it rains?" Hongshang Wuyi continued to ask.

"That's right, Mai would rather get caught in the rain than wear a hat when she doesn't have an umbrella." Noda Yumei on the side quickly testified.

"This -" Kudo Shinichi was stunned for a moment. This was the first time he met someone who liked to get out in the rain, but it seemed that this was his business and had nothing to do with him, and it was even less likely to be used as evidence.

"I've talked so much and wasted everyone's time, but you, a famous detective, can't even produce a decent piece of evidence. I guess we don't have any grudges. Do you really want me to come in?" Hongshang said Wu Yi shook her head.

"We don't have any grudges. I'm just doing what a detective should do. You'll find out the truth by testing it." Kudo Shinichi frowned.

"Yeah, it doesn't matter. Let's take it for testing, but don't get my clothes dirty."

After saying a few words, Hongshang Wuyi was no longer interested in talking to him.She was not so stupid as to hide ice cubes filled with cyanide in her hat.She had already thrown the ice cubes containing cyanide into the toilet while going to the toilet.

Officer Megure was also a little confused. He handed over Koshang Mai's clothes to the forensics personnel.

Yukiko and Conan are both nervous because this is the only evidence he can find so far,

"Report to the police officer, there are no toxic substances on the clothes" the dust settled.

"No, it's impossible." Kudo Shinichi couldn't accept this answer.

"Brother Kudo..." Seeing this, Officer Megure was disappointed. When he returned after missing for a while, Kudo Shinichi's reasoning ability was no longer good.

Qin Xuan was also surprised by this result.

It can only be said that the criminal in Ke Xue's world is not that stupid and deliberately sent evidence to the detective.

It is also possible that Kudo Shinichi's luck was robbed by Qin Xuan, and his wisdom aura is not so useful.

In the original plot, Mingming Hongshang Wuyi could just throw away the ice cubes containing cyanide, but she didn't. Even if she put it in the hat, she was not afraid of the ice cubes containing cyanide melting and volatilizing and poisoning herself. .

Here, Hongshang Wuyi did not make such a stupid and unreasonable mistake.

The Mumu Police Department was disappointed with Kudo Shinichi and could only put its hope in Qin Xuan.

Qin Xuan said calmly: "I think you are right, Memu Police Department. The victim committed suicide. The murderer who killed Kamata Kohei was actually himself."

Hearing Qin Xuan's words, Mumu Police Department couldn't hide the smile on his face. He couldn't help but feel proud. It was amazing that he had defeated the detective.

Megure Police Department coughed and said, "It seems that you made a mistake this time, Brother Kudo."

"No, that's not the case. Kamata Kohei did not commit suicide."
