Such a big city.
It is obviously difficult to find someone who spreads small advertisements everywhere.
Therefore, when a certain Kaitou boy found that the old man named Ye in front of him was still drinking coffee calmly after eating and drinking, he couldn't hold back and asked in a low voice:
"Brother, are you at your wits' end?"
"Be calm, some things can't be rushed." Ye Gengyi looked out the window casually.
This action makes no sense... Kuroba Kaito had confirmed it through observation and asked:
"...Then what are we waiting for?"
"Decoding." Ye Gengyi said.
decoding?
"What code to decode..."
Kuroba Kaito blinked.
It’s not that he doesn’t understand the meaning of this word, but the problem is:
"...Brother, you have been drinking coffee all the time."
"Of course the process must be left to computers. How can the human brain handle it?"
Ye Gengyi took another sip of coffee and said, "Wait a little longer, there are still ten minutes left. Of course, if you want to try your luck by looking around on the street like a fool, just keep in touch... I don't have any objections." .”
"Well……"
Kuroba Kaito scratched his head: "Brother, can you explain it in more detail?"
From the bottom of his heart, a certain Kaitou boy admired Ye Gengyi's ability, otherwise he wouldn't have stayed with him to continue this behavior that seemed to be a waste of time.
After Ye Gengyi confirmed that no one around was paying attention to this table, he continued: "Do you know what 'yellow dot' tracking is?"
"Huh? 'Yellow Dot'... tracking..."
Kuroba Kaito repeated the term and shook his head: "I don't know, what is that?"
No wonder there is no relevant content on the Internet. It seems that it is still a secret at this time...
Ye Gengyi said:
"The agreement signed by the U.S. government and some mainstream color printer manufacturers will form invisible watermarks in the printed documents of the equipment. Well...the diameter is almost less than 1 mm, and it is composed of some very light yellow dots. A matrix that records various information about the printing device."
? ! ? !
"What...um..."
Kuroba Kaito quickly covered his mouth to prevent the exclamation from spreading throughout the restaurant.
He took several deep breaths, calmed down, and quickly took out the A4 paper from his pocket for observation...
However, he almost put the face sticker on it and still couldn't see any similar traces.
"Invisible to the naked eye..."
Ye Gengyi used the nano-robot to mimic a high-power magnifying glass and handed it over: "Here you are, and a little more normal... Don't lie down on the table, it's too eye-catching."
"oh oh."
Kuroba Kaito took it, adjusted his sitting posture and began to observe.
After a while, he found the yellow dot matrix Ye Gengyi had mentioned in the upper left corner of the paper.
really have!
Instantly, a chill spread throughout his body.
Ye Gengyi took back the 'high-power magnifying glass' and said calmly: "Don't worry, I have already paid attention to the one you have. The black and white printer does not have this function."
"hehe……"
Kuroba Kaito laughed a few times and whispered: "But... this is too scary."
"It's scary. When electronic technology products become a necessity of life, individuals will almost become transparent."
Ye Gengyi said 'hmm' in agreement:
"The 'yellow dot tracking' function is very effective for internal investigation in an organization. If it is placed outside, it is more difficult to find. It cannot be used publicly in case handling at present. However, this person wanders around the streets and alleys specifically to spread Flyers, we don’t need to notify the official.”
"Hey, that's right, brother..."
Kuroba Kaito fumbled with the paper and quickly thought of a question: "Are the 'codes' left by different printers decoded in the same way?"
"uncertain."
Ye Gengyi said:
"This kind of analysis is based on reverse engineering. It cannot make a complete analysis of each model version. However, this is only the first step of the investigation. We will collect some papers later and only need to use certain data to The time he printed, and then the time he distributed the papers, looked for witnesses to determine the general route of his dispersal, and finally estimated the scope of his activities based on his footsteps, well..."
Ye Gengyi paused briefly, took another sip of coffee, and continued:
"That's all for now. If more information can be found during the investigation, the plan will be fine-tuned."
"Brother...you are too strong." Kuroba Kaito sincerely admired him.
"oh."
Ye Gengyi's reaction was dull. After reading the email he had just received in his pocket on his retina, he did not get up and leave. Instead, he turned his head and looked out the window again.
Kuroba Kaito: "..."
I learned it, I learned it. Sure enough, this is 'other people's child'... Huh? That is……
…
The roar of the bell awoke me;
I am a long-nosed wizard who lives in a castle;
I stuffed my stomach with hard-boiled eggs that were as cold as corpses;
Just top it off with a whole pickle;
By the way, I have to order the celebration cake first;
The ringing of the bell again arouses my hatred;
It revived my feelings of hatred and told me to use two swords to end a past pain once and for all.
Strange, according to my reasoning, the code should refer to the location...
However... the British Museum, Buckingham Palace, Hyde Park.
Conan held the map of London and didn't bother to wipe the sweat from his forehead. He just kept scratching his hair with his hands:
"How could it be wrong..."
He has definitely searched several well-known scenic spots, but unfortunately, he has not found any suspicious people spreading leaflets...
"Xin, Xinyi... don't run so fast, I can hardly catch up..."
Dr. A Li said out of breath: "To find clues separately, you should ask Brother Maori or Xiaolan to follow you..."
...Speaking of which, his exercise has seriously exceeded his standards along the way.
"Please, how can that be done?"
A certain detective boy said confidently: "If I accidentally reveal the true nature of 'Kudo Shinichi' when interpreting the code, it will be very bad if any of them sees it."
No, you have exposed a lot...
Dr. A Li complained in his heart, and suddenly thought of something: "By the way! Otherwise, how about sending the code to Genichi? He is so smart, maybe he can figure it out in no time."
Conan: "..."
This sense of déjà vu... I seem to have the impression that others used this tone to send emails to me. Doctor, am I no longer your first choice for solving the mystery?
However, slander is a slander, after all, it is related to human life. Conan did not hesitate much and sent the coded photo taken on his mobile phone to Dr. Ali, and then thought about it and reminded:
"Doctor, you only need to ask Brother Gengyi to decipher the code. Don't tell him anything else."
He was worried that if something else happened, it would be difficult to tell lies later.
"Well, I understand."
Dr. A Li nodded, inserted the photo of the code into the email, and sent it with the sentence "More one, this may be a murder notice, please try to see if you can unlock it."
At this time, Conan suddenly stopped.
I noticed something strange about my old friend next to me.
Dr. A Li looked down and saw a certain detective boy staring blankly across the road, with a look of surprise and hesitation on his face that had not dissipated, and whispered softly:
"Why...why is he here..."
