    "This method is very advanced, but I have a simpler method."

    Kamikawa Shun said, twisting the bottle cap in his hand. He used a technique to unscrew the entire bottle cap. The sealing ring that should have been left on the bottle mouth was still on the bottle cap. It looked like the entire bottle cap had not been screwed on.  Same.

    Then, he screwed the bottle cap back on, and the whole bottle looked normal, just like an unopened bottle.

    Amuro Toru took the bottle from his hand and looked at it carefully. The mouth of the bottle seemed to have never been opened. He unscrewed the bottle cap with his hands, but he did not unscrew the sealing ring together like Kamikawa Shun did. Instead, he left it on  On the mouth of the bottle.

    "How did you do that?" Toru Amuro looked at Shun Kamikawa with complicated eyes. Where did he get all these weird skills?

    ¡°When I was unscrewing the bottle cap, I accidentally unscrewed the entire bottle cap together, and then I studied it.¡±

    Shun Kamikawa really wasn¡¯t lying. He did accidentally unscrew the entire bottle cap when drinking water at first, and then n ways of counterfeiting sealed mineral water popped into his mind.

    ¡°Two of them are just like what Toru Amuro said, but they are too troublesome and there is a risk of being discovered. How can it be easy like this?

    Even if you can't unscrew the bottle cap completely, you can just buy a bottle cap. Once you snap it on, there will be no trace of it being opened. If you are not on guard, you can easily get caught.

    Amuro Toru was silent for a while, not knowing what to say. Genius and crime are indeed only one step away.

    Conan¡¯s eyes on Kamikawa Shun are also very complex. If Kamikawa Shun takes the road of crime, it will definitely be a T0-level terror.

    Kamikawa Shun was a little unhappy, what kind of look does this guy Conan have?

    "You look at me like this, are you afraid that one day I will poison you quietly?"

    "Well"

    Conan was speechless for a moment.

    What should he say?

    Kamikawa Shun slapped his head angrily, "If I want to cause trouble someday, I'll put sleeping pills in the water, tie you up, set up a camera, and spank you."

    Conan: ""

    Conan felt his butt hurt again. He didn¡¯t want to talk to this person anymore

    Ignoring the autistic Conan, Kamikawa Shun and Amuro Toru continued chatting.

    ¡°This box shows signs of being resealed. Although the prisoner carefully tore off the tape, traces were still left.¡±

    Kamikawa Shun pointed to the cut tape on the carton and said: "The color of this layer is a bit lighter than the surrounding ones, and the prisoner didn't blow it very well, so the end here is a little sticky."

    "If you want to peel off the tape without damaging it, you can use an electric hair dryer. I tried it. It can be peeled off without damaging the surface after blowing it for one minute without damaging the surface. Then wipe the seal with alcohol, and you can basically achieve micro or no traces.  "

    Kamikawa Shun didn¡¯t know if Amuro Toru had ever done this kind of thing. Anyway, he had done it himself, and he wanted to pass on some experience to Amuro Toru so that he could do things in the future.

    "You actually tried it?" Toru Amuro looked at Shun Kamikawa with a more complicated look.

    "Because when I became interested in reasoning, I studied a lot of strange techniques."

    As a detective, it¡¯s normal to master various skills.

    Kamikawa's face turned red and his heart stopped beating, and he continued like a normal person, "But wherever you walk, you will leave traces. It is basically impossible to commit a perfect crime. No matter how bizarre the criminal method is, it will only delay the time for the police to find out the truth."  .¡±

    The real world is like this. Nothing will leave traces. No matter how well you think about the criminal method, it will leave traces when it is implemented. With the current situation of such advanced technology, it will only be a matter of time before you are caught.

    Kamikawa Shun¡¯s voice was not loud, but the people around him were still attracted by his words.

    Officer Megure felt that Shun Kamikawa was right, but most of the cases they encountered were done in such bizarre ways that it was hard to imagine how they were accomplished.

    There are too many cases, and it is difficult for the police to spend a lot of effort to investigate various details in each case, and then to investigate all possibilities in various seemingly unimportant details, so in comparison with detectives, they appear somewhat incompetent.

    They don¡¯t have the amazing mind of a detective to know the whole story at a glance, so they can only use stupid methods to investigate one by one.  Not everyone in the police station is the kind of careful person, and they will overlook many things, which will lead to some unjust, false and wrong cases.

    Kamikawa Shun doesn¡¯t think the police are incompetent, but they look gloomy under the aura of detectives.

    He followed his own logic and continuedHe continued: "The water cannot have been poisoned in the canning company, otherwise Mr. Mori and those who drank the water would have been in trouble by now.

    The gangster¡¯s purpose was to kill Mr. Yokouchi, and the poisoning method was basically one of the methods I mentioned.

    When you are not sure who the suspect is, the first thing to do is to investigate the suspect.  The other party's use of such a secret method to poison must have been premeditated. Judging from the time when the victim received the threatening letter, the other party had sufficient time to prepare.

    The person who poisoned the venue must know the brand of mineral water prepared at the venue and have direct access to these mineral waters.  From here, you can identify all the people who have come into contact with or have access to this box of water and lock in a range.  "

    Officer Mu Mu has pricked up his ears. The secretary who handed the water is undoubtedly the most suspicious, but before the test results come out, they need to get more information.

    He looked at Takagi, who nodded and went to investigate according to Kamikawa Shun's instructions.

    Kamikawa Shun¡¯s words continued: ¡°The murderer should have tampered with the mineral water and the box during the period from purchasing the mineral water to moving the mineral water to the banquet hall.

    The box was handled very carefully, but such a meticulous handling method cannot be done perfectly in one go. The murderer must have practiced it many times.  "

    Kamikawa Shun looked at the secretary, "Mr. Mikami, do you know how many boxes of mineral water were purchased for this memorial service?"

    Secretary Keisuke Mikami was silent for a while and then gave a number, "12 boxes."

    "With 12 boxes of water, the murderer has plenty of opportunities to try and make mistakes. Of the 12 boxes, there is always one box with the best shell. But this involves another question: when and where did the murderer do it?  of all this.¡±

    "Water must be purchased in advance. There is a time limit for renting the banquet hall. During the period when the banquet hall is opened, these 12 boxes of water will be stored. If you know where the water is, you can take advantage of it when others are not looking.  Note that there shouldn¡¯t be many people bringing tools to tamper with cartons, right?¡±

    Officer Memu glanced at Chiba, who nodded and went to check.

    The test in the Forensic Section will take time. Kamikawa Shun was not in a hurry to continue talking. Anyway, he had already locked the secretary who delivered the water. He said this just to make the murderer unable to argue.  (Remember the website address: www.hlnovel.com
