"This is a very advanced technique, but I have an easier way."

Shangchuan said as he twisted the bottle cap in his hand. He used a skill to twist the entire bottle cap off. The sealing ring that should have been left on the bottle mouth was still left on the bottle cap, and the entire bottle cap was as if it had not been twisted.

Then, he twisted the bottle cap back, and the entire bottle looked nothing abnormal, just like the one that was not opened.

Amuro Tomo took the bottle from his hand and looked carefully. The mouth of the bottle seemed to have not been opened. He unscrewed the cap with his hand, but did not unscrew the sealing ring together like Kurakawa Shun, but instead left it on the mouth of the bottle.

"How did you do it?" Amuro Toru's eyes looked at Kawashima in a complicated way. Where did he get all kinds of strange skills?

"I used to twist the bottle cap and accidentally screwed off the entire bottle cap together, and then I studied it."

Shangchuan Shun was not lying. At first, he accidentally twisted the entire bottle cap off while drinking water, and then N ways of forging sealed mineral water popped up in his mind.

Two of them are like Toru Amuro said, but if you don’t say that, there will be a risk of being discovered. How can it be simple like this?

Even if you can't unscrew the entire bottle cap, you can buy it directly. If you press it on, there will be no signs of being opened. If you don't have any defense, you will be easily affected.

Amuroto was silent for a long time and didn't know what to say. Genius and crime were indeed only one step away.

Conan's eyes when he looked at Kawashima were also very complicated. If Guwashima Shin was on the road of crime, it would definitely be a T0-level terror.

Guaikawa was a little unhappy. What kind of eyes did Conan look like?

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

"Well......"

Conan was speechless for a moment.

What should he say?

Shangkawa suddenly stroked his head in anger, "If I want to make trouble one day, put sleeping pills in the water, and then tie you up and raise your camera to spank."

Conan: "..."

Conan felt his butt hurt again, and he didn't want to talk to this person anymore...

Conan, who was in autism, continued to chat with Tomo Amuro without caring about it.

"There are signs of resealing the box. Although the prisoner carefully tore the tape open, it still left traces."

Shun Kawakawa pointed to the tape that was cut on the carton and said, "The color of this layer is a little lighter than the surroundings, and the prisoner didn't say anything so much that the end of the tail is a bit sticky."

"If you want to remove the tape without damage, you can use an electric hair dryer. I have tried it. After blowing it for a minute, you can remove the surface without damage, and it will not damage the surface. Then wipe it with alcohol to seal it, and you can basically achieve slight or tracelessness."

Mitsukawa Shun didn't know if Tomo Amuro had done such a thing. Anyway, he had done it himself, so he could send some experience to Tomo Amuro so that he could make trouble in the future.

"You actually tried it?" Amuro's eyes looked at Kawashima even more complicated.

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

As a detective, it is normal to master various skills.

Shangkawa's face was not red and his heart was not beating. He continued to say like a person who was fine, "But any trace will be left behind when you walk through it. It is basically impossible to achieve a perfect crime. No matter how bizarre the crime is, it is just a delay in the time when the police find out the truth."

This is the real world. Nothing will leave traces. No matter how well you think about criminal methods, they will leave traces when they are put into practice. With such advanced technology, it will only be sooner or later to be caught.

Shun Kawakawa was not loud, but the people around him were still attracted by his words.

Officer Memu thought that Uekawa Shun was right, but most of the methods of the cases they encountered were very bizarre and it was hard to imagine how it was achieved.

There are too many cases, and it is difficult for the police to spend a lot of effort on each case to investigate various details, and then check all possibilities in various seemingly unimportant details, so it seems a bit incompetent in the comparison between detectives.

They don’t have the amazing minds of detectives who can tell the whole leopard by just a glimpse of it, so they can only use stupid methods to investigate one by one. Not everyone in the police station is the kind of careful person who will ignore many things, which will lead to some unjust, false and wrong cases.

Kurakawa Shun didn't think the police were incompetent, but she looked very dark under the aura of the detective.

He followed his logic and continued: "The water cannot be poisoned in the canning company, otherwise Mr. Maori and those who drank the water had already had an accident now.

The purpose of the gangster is to kill Mr. Yokonai, and the method of poisoning is basically one of the methods I mentioned.

When you are not sure who the suspect is, the first thing you have to do is to check the suspect. The other party must have planned to use this secret method to poison it. Judging from the time of the intimidation letter received by the victim, the other party has enough time to prepare.

The person who poisoned must know which brand of mineral water prepared in the venue is, and who can directly contact these mineral water. From here, you can find out all those who have contacted and have the means to contact this box of water and lock in a range."

Officer Meguri had already raised his ears. The secretary who handed the water was undoubtedly the most suspicious, but they had to get more information before the test results came out.

He looked at Takagi, Takagi nodded, and investigated as what Ukawa Shun said.

Shun Kawakawa's words continued: "The murderer should be doing the mineral water and boxes during the period from purchasing mineral water to moving the mineral water to the banquet hall.

The box was handled very carefully, but such a meticulous way of handling cannot be perfect in one go. The murderer should have practiced it many times."

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

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

"The murderer has a lot of opportunities to try and make mistakes in 12 boxes. There is always a box with the shell that is the best to uncover. But this involves another question, when and at what venue the murderer did all this."

"The water must be purchased in advance. There is time to rent a banquet hall. During the period when the banquet hall is opened, these 12 boxes of water will be stored. There should not be many people who know where the water is placed and can take tools to tamper with the carton while others are not paying attention, right?"

Officer Memu glanced at Chiba, Chiba nodded and went to investigate.
