Kiyomi Ruri's curiosity is very strong, and if she encounters something she doesn't understand, she will keep thinking about it, so that she can't eat well and sleep well, but she's not so curious that she even thinks about changing change for others.

She said inexplicably: "It's just changing change, what's wrong with this, isn't this kind of thing very common?" ”

"It's common to change change, but as long as 10 yen, the more you have, the better...... Is it common? ”

Kiyomi Ruri still didn't take it seriously, and said casually: "That uncle may be in a small business, and the things he sells may be very cheap, so there is nothing strange about preparing a large number of ten yen coins to facilitate change." ”

"Then why didn't he want a five-yen coin? If you are doing business and making change, what you can do with 10 yen coins, can't you do it with 2 5 yen coins? Nanahara Takeshi finally left, and said as he walked, "There were a lot of five-yen coins in the cash register, and the clerk asked him if he wanted it, and he refused. ”

"Uh......"

Kiyomi Ruri was asked, and he couldn't think of the reason for a while, and was about to ask Takeshi Nanahara, when his heart suddenly moved.

Why did this kid talk about such a trivial thing inexplicably, could it be to challenge my deductive reasoning ability?

Or, if I can reason, it proves that the deductive reasoning method is really strong, then he should realize his shallow ignorance and honestly join my club, right?

Thinking of this, her dark eyes lit up, and she felt that her whole person was on fire, and she immediately started to think hard.

Why did the man only need ten coins?

She thought for a while, and said cautiously: "Maybe he just finished drinking with his friends all night, and he said in advance that it was AA system, for example, everyone should pay 1190 yen, and he was responsible for settling the bill, but everyone gave him 1200 yen, so he had to find 10 yen change for each friend - he is a very serious person, even if the ten yen money is very small, he has to return it to his friends as agreed, and at the same time, he is afraid that his friends will refuse, and the scattered coins are not easy to shoe, so he collects a large number of 10 yen coins!" ”

Kiyomi Ruri felt that this reasoning made sense, and looked at Nanahara Takeshi expectantly, wanting to see the look of surprise and admiration on his face.

Nanahara Wu didn't even tease her out of the corner of his eye, shook his head and said: "That's impossible, it's not a problem to mention two five yen, you can just stuff it to a friend, and don't mention that he actually has Yaxing and more than twenty people, or even thirty or forty people to drink wine overnight - he has changed more than a dozen coins before, and he has exchanged nine more from you, plus he already has, and now he has a lot of ten coins in his hand."

Even if he had the grace to drink all night with so many people, the number of friends was always fixed, and when you asked him how many coins he needed, he would always tell him the number, such as five, ten, fifteen, etc., and he would not be able to say to you, 'The more the merrier'. ”

"Uh......" Kiyomi Ruri thought about it carefully, and felt that what Nanahara Takeshi said made sense, his reasoning was too taken for granted, and then pondered for a moment, "That's ...... Is he going to visit the shrine to make a vow? ”

Speaking of this, her eyes lit up, "Yes, he is going to visit many shrines, so he needs a lot of ten yen coins, and he wants to double it!" ”

The pronunciation of five yen in Japanese is similar to "有缘", so when I go to the shrine to make a vow, most of the people who throw money (similar to incense money) will use five yen or multiples of five yen, such as 10 yen "double fate", 15 yen "very fate", and even 485 yen "fate in all directions", all of which have special meanings.

Kiyomi Ruri felt that her reasoning made sense, and Nanahara Takeshi was speechless for a moment and asked, "A shrine costs ten yen for double marriage?" Then he plans to go to more than 20 or even thirty or forty shrines in one day, do you think it is possible? ”

"Well, if you run faster, you should ...... It should be possible to complete it, right? Kiyomi Ruri was shaken, and felt that this reasoning didn't seem to be very reliable, but she pouted and said unconvinced, "Then why do you say he changed so many ten yen coins?" I have at least some reasonable ...... Barely reasonable reasoning, you didn't think of anything! ”

"There must be something that only ten yen coins can do, and it can't be replaced by other coins......" Nanahara Takeshi suddenly took a steady step, almost letting Kiyomi Ruri bump into him, and suddenly realized, "I see, that guy is most likely a void breaker." ”

"Huh? That uncle is a thief?! Kiyomi Ruri's eyes widened, and she quickly turned her brain, but she still couldn't figure out how Nanahara Takeshi reasoned about it.

"Probably, it's very suspicious."

Nanahara Takeshi figured it out, so he didn't take it to heart anymore and continued to walk towards the station. Kiyomi Ruri was itching, grabbed him and asked, "You make it clear, why did that uncle become a thief?" ”

"Do you understand? Do I want to buy the Q&A service? Nanahara Takeshi looked at Kiyomi Ruri's pocket.

You damn money-hungry guy!

Kiyomi Ruri Muran took out his wallet, took out 500 yen and slapped it on his hand, and said angrily: "Say it quickly!" ”

Nanahara Takeshi immediately smiled after receiving the money: "In Hirano, what do you have to use ten yen coins?" ”

Kiyomi Ruri had a bad attitude, "I don't know, that's why I asked you, hurry up and say it directly!" ”

Nanahara Takeshi smiled: "Call the coin-operated public phone!" The guy had to make a lot of pay phone calls, so he needed a lot of ten coins. ”

Before mobile phones were cheap enough for everyone to afford, there must be phone booths on the streets.

Usually it's a coin-operated type, and for every 10 yen you put in, you can talk for one minute, and when the time is up, you can put in another 10 yen, and you can continue for another minute, and so on.

Of course, you can also directly put in a hundred yen coin and say ten minutes, but the money will not be refunded until the time is used up, and the phone booth will not give change.

Coin-operated phone booths only support these two coins, and in the next few years, there will be more and more phone booths that can use IC cards.

At its peak, there were more than 2.1 million public telephone booths, and even in 2020, this thing has not completely disappeared, and there are still 270,000 units remaining, but most of the people who use them have become tourists.

It's been more than half a year since Nanahara Wu crossed, and he doesn't have a mobile phone, of course, he has used a public phone, but the number of times is not too much, so he didn't expect it for a while, and after figuring out this, it is natural to judge that guy is a thief.

Kiyomi Ruri hadn't figured it out yet, and hesitated: "Even if he wants to use a public phone, how did he become a thief?" Everyone has access to a pay phone, right? ”

"Stupid, you're such a pig's brain!" Nanahara Takeshi said unceremoniously, "He exchanged so many ten yen coins, and asked for as many as possible, obviously he had to make many calls with a short call time, and he didn't know how many families he wanted to call, so what was he going to do, telemarketing?" ”

If it's a telemarketer, he definitely won't use a public phone, this Kiyomi Ruri can figure it out, and suddenly said thoughtfully, "So, he wants to test whether there is anyone in the family?" If there is no one at home, he will find a way to touch it and take the valuable things? That's why you say he's a thief who broke through the empty door? ”

Phone numbers are not difficult to get, and people don't pay that much attention to the privacy of their communications these days.

On the contrary, at this time, people are still afraid that others will not be able to contact them, so they will take the initiative to put their address, surname, and phone number in the phone book of the telephone company - almost every phone booth has it, and they hang it there with a string, for example, if they want to call Kiyomi Ruri, they will first turn to the Kamimi area, then find Tamachi, then find the page of Higashitamamachi, and finally find Kiyomiya.

Even as far as Kiyomi Ruri knows, there are many people in their town who have their own phone numbers on the circulation boards to facilitate telephone communication between neighbors, and the end of all circulation boards is next to the bulletin boards, and there are often several hanging there, and anyone can read them, and no one cares about them.

Kiyomi Ruri felt that Takeshi Nanahara's reasoning seemed to be really reasonable, and Takeshi Nanahara nodded and said, "Most likely, yes, if you need to make a lot of calls on serious matters, why doesn't he go to a friend to borrow a phone?" When using a public telephone, it should be feared that before committing the crime, they will make a dense silent call to a certain area, which will arouse the suspicion and investigation of the police afterwards. ”

After a pause, he touched his chin and smiled, "If it's true, he is a thief with brains, and the economic conditions of people with telephones will at least not be too bad, so that he will not be allowed to run empty, and in about half an hour, it will be the shift change time, and the patrol police will go back to hand in the shift to write a report, and everyone who should go to work and school has also gone out. ”

The more Kiyomi Ruri listened, the more she felt that this was the case, and recalled the man's dress, the inconspicuous off-white overalls, the light rubber-soled shoes, and the inexplicable carrying a shriveled backpack, and immediately said urgently: "Then let's go and hand in the report!" ”

Nanahara Takeshi turned a deaf ear and continued to walk forward, and said with a smile: "This is just speculation, I don't have evidence, I can't guarantee that this is the case, it's not good to tell the police, what if that person just has a quirk of collecting ten yen coins?" Isn't that a nuisance! ”

"Who would have that quirk!" Kiyomi Ruri is in a hurry, and the person suspected of being a thief has entered the town where she grew up, so she can't do it in a hurry, "Go and talk to the police about your reasoning, maybe you can catch him!" ”

"I'm not going, I don't want to be late for school just started, and ......" Nanahara Takeshi broke free of her hand and started to pit directly, looking back and smiling, "You don't need me to go, someone will go." ”

Kiyomi Ruri wondered, "Who will go?" ”

Nanahara Takeshi smiled at her again and left, Kiyomi Ruri was stunned for a moment and reacted - bastard, this kid thinks I will definitely go, so there is no need for him to waste time!

She really wanted to gamble with Nanahara Takeshi, she didn't go, to see what he would do when he arrived, but she hesitated, and after all, she didn't dare to enter the station with him to take the train, so she stomped her foot and turned around and ran to Jiaoban.

Nanahara Takeshi has no feelings for the town, but she does, and she really can't ignore it.
