The man is rather strange. , because he walked out of the convenience store with a pack of "Huang Heping" (a Japanese cigarette brand). And just outside the convenience store, there is still a stock of "Peace" in the cigarette vending box.

And... Qian Yu focused her gaze on the plastic bag in the man's hand.

If memory serves, this pigment is not commonly used in painting, but if it is dyed in the bark pulp of the incense tree (the basic material of Japanese banknotes, also known as the bark pulp. It's one of the first-class options for imitating watermarks - at the beginning, Qianyu's wooden work was gnawed by termites that appeared somewhere, and Qianyu was so distressed that he immediately changed the material for making his gadgets from ordinary wood to a fragrant tree that can repel insects, and placed a circle with the bark of the incense tree next to the work that was not gnawed. Later, a member of the organization found a piece of incense tree lying in Master Chiba's workshop and was about to leave the bark of the incense tree. When Chiba, who had given him a small artifact that suited his appetite, asked him outside the hallway why he needed the bark of the incense tree, the member told Chiba about it.

Buying cigarettes at a convenience store is suspected of making counterfeit money... I'm afraid that the money it used to buy cigarettes at convenience stores is also a counterfeit banknote, right? Considering that Shunya's brother is good at drawing Natsume Soseki printed on the 1,000 yuan bill, and considering that using the 1,000 yuan bill is definitely a very reasonable option for buying a pack of cigarettes. I'm afraid Shunya's brother definitely has a close relationship with this guy.

But then again, these guys are really conspicuous... The money printing materials in the organization are based on cars, and I think the relevant material suppliers have been arranged. The pattern of these guys is much smaller, and it is estimated that those people who got the formula of the banknote material by chance want to gamble, right?

"You bring them back," at that moment, Chiha's shoulders suddenly strained, and Conan's voice appeared in his ears. "I need to follow this man. Call the detective agency at 11 p.m., and if I'm not there, you'll tell Uncle Maori all these things. ”

"You..." Qian Yu was slightly stunned.

"Please." Conan's tone was resolute. "I beg you, do me a favor."

"Oh... Good... Qian Yu thought about it, and finally nodded.

Under Chiba's gaze, Conan hurried after the man.

"What did Conan-kun do?" Ayumi also found Conan, who had quietly left the team, and asked curiously.

"He went to the bathroom." Qian Yu lied without changing his face.

"Edogawa's lunch was a fresh bento, and he had already gone to the toilet after the second class this afternoon, and it came out a few minutes later. He didn't ingest anything like cold water that can cause a serious gastrointestinal reaction today, and he didn't catch a cold just now. "Gray Yuan looked at Qianyu with the expression of a fool." Excuse me, how could he still want to go to the toilet now? What's more, the toilet is not here. As he spoke, he pointed to a public toilet on the opposite street from where Conan had left. We had just come from over there, and unless Edogawa was a prophet, he would never have known that there was a public toilet here. So, Chiba-kun, can you tell us, did Conan do what to go? ”

“。。。” Qianyu looked at Gray Yuan Wai blankly, not knowing how to answer.

And... How did you know Conan so well??? What you're saying is amazing!! Are you following Conan all the time???

"Since you don't plan to say it," Gray Yuan Wai saw that Chiba didn't react, and shook his head with a smile. "Then let's go after Edogawa ourselves."

"Hey, hey..." Only then did Qian Yu react. "You guys!"

。。。

Chiba looked blank and followed behind Ai Ashbara, Mitsuhiko, Motota, and Ayumi, watching Conan in front of him buy a ticket in front of the ticket machine, and then walked into the tram stop. When the group arrived at the ticket machine, they didn't know which station Conan was going to on the train.

“。。。” Qianyu's eyes were good, and he naturally saw the position of Conan's finger on the button on the ballot machine, and naturally knew where Conan went, but he didn't plan to tell these guys - to put it mildly, if they were also involved in Conan's operation, it would almost certainly be a burden.

However, Gray Plains deduces in a miraculous way where Conan went.

Gray Yuan leaned over slightly, looked at the button, and after a moment, she decisively pressed the ticket booking option for a station. Then, Gray Yuan looked at Qianyu - Qianyu's jaw was slightly deformed, apparently biting her lip. "Looks like I guessed right, and sure enough, it's to Daduma Station."

Qian Yu's eyes instantly changed back to an indifferent state without any emotion, and he didn't say a word. However, in his heart, he basically already knew how Gray Plains Wai discovered the site chosen by Conan.

Conan had done a lot of physical labor in order to find Shunya's brother before, and his body was covered in sweat and salt, and if he pressed the button, he would definitely leave some marks more or less. Just by extrapolating from this clue, you can determine which keys Conan pressed.

Gray plain mourning, who are you sacred?

。。。

When the group boarded the train in the direction of Odoma, the sharp-eyed Mitsuhiko saw Conan sitting in another car, and the group lurked in a place where Conan could not see, waiting for the train to arrive at Odoma Station.

"Whew..." After the train arrived at Odoma Station, Conan took a look at the buildings around him. "If you want to print money, you need to ...

A hand crept up on Conan's shoulder and patted it.

“！！！” Conan looked back in surprise, only to see someone he hadn't expected. "How could you ... A thousand feathers? ”

"A shrewd person didn't believe me at all." Qian Yu pursed his lips. "I've done my best."

"What the hell did you find?" Gray Yuan said lightly. "Mind telling us about it?"

“。。。” Conan sighed and began to tell everyone about his reasoning - the specifics were similar to what Qian Yu had in mind.

"So what should we do next?" Chiba glanced at the buildings lining the train outside the station. "Obviously, you didn't keep up with that guy, did you?"

"He was one bus ahead of me because he caught the bus." Conan said helplessly. "If I hadn't glued the transmitter to a bill and handed it to him, I wouldn't have even been able to follow him to the station. I can know that when he arrived at Daduma Station, he still had the information provided to me by the aunt who entrusted the newspaper stand and the uncle who swept the floor. ”

"Still, there is a way to keep track of it," Conan said, gesturing to a housing agency not far away. "If it is money printing, renting a house is definitely a relatively low-risk option that is not easy to find out the real identity. Let's go there and take a look, maybe we can find some clues. ”
