The goal is the Faculty of Medicine of Dongdae

Skipping the long list of introductions about the identity of the deceased and the cause of death, Police Officer Higurashi looked at the few people who were roughly identified as having been to the bathroom and the deceased's companion.

"Please introduce yourself first and answer our questions."

"What?! Isn't this treating us as murderers!" One of the women seemed to be very angry and shouted, "It's too much!"

"Please calm down, Ms. Katori, we are just asking a few questions on a routine basis." Takagi tried to reassure, and Police Officer Megure coughed, "Brother Mori and I are just recording the testimony of everyone. After we determine that there is no suspicion, we will Will let innocent people go."

Morintaro, who was ranked last and kept quiet, rested his thoughtful eyes on those companions. According to the chain of suspicion, he who had nothing to do with the deceased should be the first to rule out the suspicion.But according to his observations just now, the deceased's earlobes were cherry red, his face and lips were cyanotic, and if he could still smell almonds, he should have died of cyanide poisoning.

Alas, I really want to dissect... Morin Taro sighed, and winked at Saiki Kusuo who was excluded and stared at him.

[Kusuo knows who the murderer is~ It's XX, right? ]

【... Now that you know it, solve it quickly. ] Saiki Kusuo, who was afraid that the other party could not help making troubles, quickly said that he was really afraid that some guy who was afraid of chaos would say something amazing.But the black-haired boy looked at him innocently, [I have no evidence, and I'm not a detective, just an ordinary medical student. ]

Go to hell, can ordinary medical students see the truth before these policemen and detectives on the scene.

……

"My name is Mori Ogai, and I'm currently a sophomore at PK Academy. I just came to eat dessert with my classmates and my sister, and I don't know this woman at all."

The black-haired boy smiled obediently, but his eyes fell on a certain elementary school student who was wandering around: "As for why you are in the bathroom, because my sister and I are angry, I just came to coax her .”

"Hmph, Lin Taro can only lie to Jasmine, but every time he agrees on the quantity of small cakes, he always eats them while Jasmine is not paying attention!" Staring at the young man, "Uncle Police, hurry up and arrest this deceitful villain."

"Jasmine sauce, don't be angry, okay?" The boy who had an obedient face just now rushed over to embrace the little girl as if changing his face, "This time, I will definitely, definitely buy Jasmine's favorite little cake." ! Jasmine can eat as much as she wants, and she will never break her promise!"

"Let go... let go Rintaro! You're going to wrinkle Jasmine's skirt like this!" The little girl tried her best to push the boy who was holding her tightly, but it could be seen that she didn't resist so much.

"Uh...you brothers and sisters have such a good relationship..." Takagi said awkwardly.

"The only one in the bathroom is Jasmine, you don't think Jasmine sauce is the murderer!" The young man thought of something, staring at the policeman in front of him vigilantly, Takagi waved his hands repeatedly, "How could it be, how could we treat children as criminals? .”

"That's good, Jasmine must be terrified!" The boy reached out and rubbed the top of the little girl's soft head with a nervous expression, and was slapped away mercilessly, "Hmph, Jasmine won't be so timid!" Woolen cloth."

"Yes, yes, our Jasmine is the bravest and cutest girl in the world!"

This is a bear child and a bear parent who dotes on the child... Conan accidentally glanced at this scene and looked away silently. He really didn't see that he was already a mature person when he was 12 years old. He still had to think about the murderer How did he manage to leave without a sound after being poisoned?

"I think, Police Officer Megure, this young man should not be suspected. He doesn't know the victim, and it is impossible for him to bring his young sister to commit the crime." Mori Kogoro said.

Police officer Mumu nodded in agreement: "In this case, Mori-kun can make a record aside, and after finishing it, wait for the forensic department to come and make sure there is no problem before you can leave."

"Okay, thank you very much, Mr. Police." The boy who was holding the little loli returned to his previous gentle and polite appearance, and he said casually, "Jasmine said just now that she only heard one person's footsteps when she entered, Does this mean that the murderer did not poison the bathroom?"

The young man's words attracted everyone's attention. Officer Higurashi touched his chin and nodded thoughtfully: "Then, did you poison it while you were outside?"

"But the cause of death of the deceased was cyanide poisoning, which is a highly poisonous poison that occurs immediately after ten seconds of entrance." Takagi said immediately, "If the poison was taken while eating, how could the deceased go to the hospital? Is it because of the toilet poisoning?"

"Reporting to the police department, we found cyanide mixed with powder in the cold capsule in the deceased's bag. At the same time, we also found a similar capsule in Miss Limu's bag."

"What? I did buy the same brand of cold medicine but I didn't know it was poisonous!" The woman with half-ball hair called Limu had an unbelievable expression on her face, "That's right, Qianhua, are you See Xiaochun and I went to the pharmacy to buy medicine together! I still have the receipt from that pharmacy, you can check it!"

"But that doesn't mean you didn't murder the deceased with poison. Officer Higurashi, it's very likely that you bought the same brand of cold medicine for the convenience of changing the medicine. As long as you find a time when the deceased is not paying attention, you can change it secretly. The deceased is It is very easy for those who are used to packing capsules in small bottles,” said Mori Kogoro.

"Ah indeed, Xiaochun asked for a cup of boiling water and took a cold medicine when she drank drinks today." The male in the same company said, "But at that time we were all sitting face to face, how could Limu exchange under the eyes of all of us?" ?”

"Don't forget that we went shopping before. When changing clothes, the bag is left to someone else to look after. Wouldn't it be easy to secretly change it at that time?"

"What do you think I killed Xiaochun? Katori, you are still very upset because of your makeup clash with Xiaochun today."

"It was just an accident that caused me to be a little unhappy. How could I kill someone because of this kind of thing? It was you, Li Mu, Xiaochun, who made out with your ex-boyfriend in front of you before, and you were very angry."

"Stop arguing, Ms. Li Mu, you are now suspected of killing Ms. Dashan, please go to the police station with us." Gao Mu said seriously, and took out the handcuffs.

"It's not really me!"

"Let's talk about the specifics at the police station."

Everything seemed to be in order, Conan frowned secretly, but he always felt that something was wrong, what point did he overlook...

"I've also bought this brand of cold capsules before." The young man who had been watching quietly with a smile on his face spoke again. He put one hand in his pocket calmly, and gently stroked the top of Jasmine's hair with the other hand. "The dissolving time of this kind of capsule in hot water is about 5 minutes. If the deceased entered the bathroom after Jasmine, theoretically, the poison should have occurred long ago. But what Jasmine heard was the sound of the deceased washing his hands, probably After an interval of ten minutes, there was the sound of the compartment door opening."

"For such a long time, if it is this kind of cold capsule, the coat should have been dissolved in stomach acid long ago."

"This..." Mori Kogoro was a little embarrassed, the eyes of a pseudo elementary school student next to him lit up, yes, this is here, although he has never eaten this brand of capsules, but he also knows that ordinary capsules take about five to 10 minutes will dissolve in stomach acid.

"Unfortunately, I have a little bit of research on medicine." The young man said with a smile, "In addition to the capsules that are generally soluble in gastric acid, there is also a capsule that is insoluble in water and acid. It takes longer Time will work..."

"Enteric-coated capsules! The human stomach is acidic but the intestinal tract is alkaline. Enteric-coated capsules will only dissolve in an alkaline environment, and it usually takes more than two hours to take effect."

Conan, who was saying this, suddenly noticed the surprised eyes of everyone looking at him, and immediately stuck out his tongue like a child: "That... hehe, I found out from watching health programs on TV."

"You kid, why do you watch messy programs every day?" Mori Kogoro snorted coldly.

"Little brother is very smart. It doesn't look like a child to know this kind of professional knowledge at such a young age." Morin Taro glanced at Conan who seemed to have a stiff smile, said with a smile, and was immediately upset The little loli stepped on her foot, "Sorry, sorry, Jasmine is the smartest and cutest. I like Jasmine sauce the most!"

He clasped his hands together and looked at Little Lolita as if flattering him, and rubbed Jasmine's hair in a comforting manner, until she puffed up her face in displeasure.

"I remember... Katori seems to have gone to the gastroenterology department before, and I heard that he has enteritis." While talking, the companion looked at the impatient woman with shocked eyes, and the woman seemed to have a momentary expression. After a rapid change, he immediately returned to his arrogant look, "It's funny, does it mean that I'm a criminal because I have enteritis? According to this, the patients in the gastroenterology department of the hospital are all criminals? You don't have any evidence at all, do you? "

"Indeed, after all, enteric-coated capsules are medicines that take at least two hours to take effect. According to what you said, you went shopping in the morning to buy drinks. I think you probably put the capsules in colored drinks, and you should also You wouldn’t be so stupid as to put other capsules on your body, even if the police search your home, they will only find the rest of the ordinary enteric-coated capsules, there is no direct evidence at all.”

The black-haired boy who still spoke in a calm and gentle tone didn't look like he was in a hurry as he said 'no evidence', and he ignored the gritted teeth of the policemen, even Conan, I can't think of any direct evidence at the moment.

Damn it, do you want the prisoner to leave openly in front of their eyes!Just like what the boy said, if no evidence can be found, we can only deal with it as suspected crime!

"I don't know what you're talking about. I'm just a patient with enteritis. It's really bad luck that I should be treated as a prisoner for this reason!"

The smug look in the woman's eyes flashed away, and she still had an impatience and arrogance with her hips akimbo.

"It's also impossible to check your hands. You must have washed your hands after making that poisonous capsule."

The young man stared into the woman's eyes, those purple pupils were like a pool of red wine, under the refraction of the light, there was a bit of illusory coldness.The woman flinched subconsciously. This is nothing more than a clever student. How could it suddenly give her a terrifying feeling that she seems to see through everything...

"Thousands of miles of long dams, what destroyed it was nothing more than a small ant nest." Under everyone's gaze, the young man suddenly showed a very faint smile, and his slightly long hair was like black inlaid jade. Pasted on the side of the porcelain-like neck, "This really seems to be a perfect criminal plan, but unfortunately, you seem to have forgotten one thing."

"Local's law of material exchange, anyone who touches will leave a mark."

"Do you have the habit of washing the faucet?"

Everyone was puzzled at first, but the woman was only silent for less than a second, and her face changed drastically.Immediately afterwards, Kogoro Moori came back to his senses: "If she wants to wash her hands, she must unscrew the handle of the faucet with her finger that has been exposed to poison. Most people don't have the habit of washing the faucet! Just test the faucet in her home. , maybe you can find the contaminated poison powder."

Even, there is no need to go for a special inspection, just looking at the gray and defeated expression of the woman after the transformation, you can know that this is right.

Shi Shi, a black-haired boy who had no interest in the prisoner's subsequent psychological activities and explanations, led Jasmine away from the encirclement, and looked at the calm pink-haired boy with smiling purple eyes: "Sorry, it's a little late."

[I can't tell, you seem to be very suitable to be a detective. 】

[No, no, it's all thanks to Kusuo who transferred the picture of that person's memory to my brain, otherwise I'm not sure if there is any trace on the faucet. ]

[I was just 'spoiled'. ] Saiki Kusuo looked at the black-haired boy, 【It is your ability to guess who the murderer is by deduction. 】

[I just observed everyone's expressions. ]

For Morin Taro, who is proficient in using micro-expressions to observe and impresses his classmates who don't know the truth as "a good student who is studious, modest, prudent, and gentle", an ordinary criminal who is not good at expression management and concealing himself can fool him almost is impossible.

"Let's go, Kusuo, don't you want to go home and watch animation?"

【...The time has passed. 】

"Ah?" Lin Taro was stunned, and seeing the policemen who seemed to be turning their heads from the corner of the eye, he immediately grabbed Saiki Kusuo with one hand and Jasmine with the other, and left the store in a hurry, "Hurry up!"

The next second, he found himself standing in his yard.

Saiki Kusuo who used 'teleportation' looked calm.

[It will be very troublesome to be remembered by the police station. 】

Especially after he heard that police officer Higurashi complained about the extremely high crime rate around Mori Kogoro, he was determined not to let himself be infected.

And that elementary school student, no, it should be that pseudo-elementary school student, Saiki Kusuo, who heard everything the other party was thinking, knew the ins and outs of everything, so you must stay away from any organization that is very troublesome to hear, and you must not get involved .

"Did Kusuo not leave because he was waiting for me?" The black-haired boy had a moved expression on his face, "He didn't even watch the anime that he had been waiting for for so long because of me!"

[No, no, your companion suddenly disappears, if you are approached as a suspect, it will scare your mother. 】

However, Morintaro completely ignored Saiki Kusuo's 'reason', and was so moved that his tears seemed to pounce on him in the next second. Seeing this, Saiki Kusuo silently took two steps back.

This distance is enough to launch a teleport when the opponent rushes forward.

But the next second, the cell phone in Morin Taro's pocket suddenly rang.

When the boy who took out his mobile phone glanced at the number on it, the corners of his lips that were raised just now were subtly retracted. He connected the phone and did not speak, just quietly listening to the person inside.

"I see, since it's been set for two o'clock in the afternoon, I don't want to be disturbed by strangers before then."

After saying this, Morintaro hung up the phone without hesitation.

"Sorry, Kusuo, can we reschedule the celebration to Sunday?"

Saiki Kusuo looked at him.

Although the black-haired boy was smiling, the coldness in his eyes was not concealed by him: "Father asked me to go back to the old house the day after tomorrow. I have something to talk to me about."

【I see. ] Saiki Kusuo, who guessed something from Morintaro's attitude, was silent for a few seconds, 【Don't be impulsive. 】

"Don't worry, Kusuo, I will come back on time to go to the Sunday celebration with you." The black-haired boy said with a smile, "It's just a 'father-son talk', there won't be any problems."

Saiki Kusuo: ... Don't think that I didn't hear the chemical names of a series of poisons and the several methods of destroying corpses that flashed in your mind just now!
