Chapter 14 The Ten Yen Coin Incident
Qingjian Liuli is very curious, if she encounters something she can't figure out, she will keep thinking about it, making it difficult to eat well and sleep badly, but she is not so curious that she even has to think about it when someone else changes it .

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

"Change is common, but as long as ten yen coins, the more the better...is it common?"

Qing Jian Liuli still didn't take it seriously, and said casually: "The uncle may be in a small business, and the things he sells may be very cheap, so it's not surprising to prepare a lot of ten-yen coins for easy change."

"Then why doesn't he want five-yen coins? If you're doing business to get change, wouldn't you be able to do what ten-yen coins can do with two five-yen coins?" Takeshi Qiyuan finally left, and said as he walked, "The cash register There were a lot of five-yen coins in the machine, and the clerk asked him if he wanted it, but he refused."

"Uh……"

Seeing that Liuli was stopped by the question, Qing couldn't think of the reason for a while, and was about to ask Qiyuan Wu when his heart suddenly moved.

Why did this kid talk about such a trivial matter out of nowhere? Could it be that he wanted to challenge my deductive reasoning ability?

Or, this matter also stumped him. If I can reason it out, wouldn’t it prove that deductive reasoning is really strong, then he should realize his ignorance and join my club honestly?
Thinking of this, her dark eyes lit up, and she felt that her whole body was on fire, and she immediately began to think hard.

Why does that man only want ten yen coins?

She thought for a while, then said cautiously: "Maybe he just finished drinking with his friends all night, and it was agreed in advance that it is AA system, for example, everyone should pay 1190 yen, and he is responsible for the checkout, but everyone gave him 1200 yen , so he has to find 10 yen change for each friend - he is a very serious person, even if the [-] yen is very little, he will return it to his friends as agreed, and at the same time he is afraid that his friends will refuse, scattered Coins are not easy to squeeze, so I collect ten yen coins in large quantities!"

Qingjian Liuli felt that this reasoning made sense, and looked expectantly at Qiyuan Wu, wanting to see the surprised and admired expression on his face.

Qi Yuanwu didn't even touch her eyes, shook his head and said: "That's impossible, let's not mention two five yen, it's no trouble, it can be forced to give to a friend, and I don't mention that he has Yaxing and more than [-] people, even Thirty or forty people drink wine for a night-he had exchanged a dozen coins before, and he exchanged nine from you, plus the ones he already had, and now he has a lot of ten-yen coins in his hand.

Even if he has the pleasure of drinking with so many people for a night, the number of friends is always fixed. When you ask him how many coins he needs, he can always quote the number, for example, five coins are short, ten coins are short, ten coins are short It is impossible to say 'the more the merrier' to you. "

"Uh..." Qingjian Liuli thought about it carefully, and felt that what Qiyuan Wu said made sense, and his reasoning was too taken for granted, so he thought for a while, "That is...he is going to pay homage to the shrine?"

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

The pronunciation of five yen in Japanese is similar to "destiny", so when Japanese people go to shrines to pay their wishes, most of them will use five yen or multiples of five yen, such as ten yen "double fate", fifteen Yen "very destined", and even 480 yen "destined in all directions", all have special meanings.

Qing Jian Liuli felt that his reasoning made sense, and Qi Yuanwu was speechless for a moment, and asked: "One shrine spends ten yen to double the marriage? Then he plans to go to more than 20 shrines, or even thirty or forty shrines in one day ,Do you think that's possible?"

"Well, if you run faster, it should be...should it be possible to complete it?" Seeing that Liuli was shaken, Qing felt that this reasoning seemed unreliable, but she pouted and said in disbelief, "Then why do you think he changed it?" So many ten-yen coins? At least I still have some reasonable...barely reasonable reasoning, and you didn't think of anything!"

"There must be something that can only be done with a ten-yen coin, which cannot be replaced by other coins..." Qiyuan Wu suddenly stood still, almost letting Qingjian Liuli hit him, and suddenly realized, "So that's the case, that guy has a high probability It's a break-in."

"Huh? That uncle is a thief?!" Qing Jian Liuli's eyes widened and she turned her head quickly, but she still couldn't figure out how Qiyuanwu reasoned it out.

"Probably, the suspicion is great."

After Qiyuan Wu figured it out, he didn't take this matter to heart, and continued to walk to the station.Seeing Liuli's itchy heart, Qing grabbed him and asked, "Speak clearly, why did that uncle become a thief?"

"Don't you understand? Do you want to buy a question-and-answer service?" Qiyuan Wu looked at Qingjian Liuli's pocket.

You money-hungry guy!

Qing Jian Liuli took out his wallet dumbly, took out 500 yen and slapped it heavily on his hand, and said angrily, "Say it!"

Takeshi Qihara took the money and immediately smiled and said, "In Hirano, what do you need to use ten yen coins for?"

Qing Jian Liuli had a bad attitude, "I don't know, that's why I asked you, please tell me straight!"

Qiyuan Takeshi smiled: "Call the coin-operated payphone! That guy needs a lot of ten-yen coins because he has to make many payphone calls."

Before mobile phones were cheap enough for everyone to use, there must have been phone booths on the streets of Japan.

Usually it is a coin-operated type. Every time you put in 1 yen, you can talk for 1 minute. When the time is up, you can put in [-] yen before you finish talking, and you can continue for [-] minute, and so on.

Of course, you can also directly put in a 10-yen coin for [-] minutes, but the money will not be refunded before the time runs out, and no change will be given at the phone booth.

Coin-operated telephone booths in Japan only support these two coins. In a few years, there will be more and more telephone booths that can use IC cards.

At its peak, Japan had more than 210 million public telephone booths. Even by 2020, this thing has not completely disappeared. There are still 27 telephone booths left, but most of the people who use them have become tourists.

Qiyuan Wu has been here for more than half a year. He doesn't have a mobile phone. Of course, he has used a public phone, but the number of times is not too many. This is what he didn't think of for a while. After thinking about it, it is natural to judge that guy is a thief.

Qing Jian Liuli still hadn't figured it out, and said hesitantly, "Even if he wanted to use a public phone, how could he become a thief? Everyone uses a public phone at times, right?"

"You're so stupid, you're such a pig brain!" Qi Yuanwu said unceremoniously, "He wants to change so many ten-yen coins, and he asks for as many as possible. Obviously, he has to make many short calls. How many calls? He doesn't even know himself, so what is he planning to do, telemarketing?"

If he was a telemarketer, he would definitely not use a public phone. Seeing that Liuli could figure it out, Qing Qing immediately said thoughtfully, "So, he wants to test whether there is anyone at home? If there is no one at home, he will find a way." Go in and take valuables? That's why you say he's a burglar?"

Phone numbers are easy to come by, and the privacy of communications is less important 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 telephone company's phone book-almost every phone booth has it, and hang it there with a thin rope. For example, if you want to call Qingjian Ruri, you should first turn to Shangmi District, then find Tamamachi, then find the page of Dongtamacho, and finally find Kiyomi's house.

Even as far as Kiyomi Ruri knew, many people left their phone numbers on the circulation boards in their town to facilitate telephone communication between neighbors, and the end point of all circulation boards was next to the public notice board, and there were often several The block is hung there, anyone can read it, no one cares at all.

Qing Jian Liuli felt that Qiyuan Takeshi's reasoning seemed to make sense, and Qiyuan Wuze nodded and said: "Probably yes, if he needs to make a lot of phone calls for serious business, why doesn't he ask a friend to borrow the phone? Using a public phone should be because he is afraid of being in trouble." Before committing the crime, he intensively made silent phone calls in a certain area, which aroused suspicion and investigation by the police afterwards."

After a pause, he rubbed his chin and smiled again, "If it's true, he's a thief with a brain. At least the financial conditions of people with a phone are not too bad, so he won't make an empty trip, and in half a year The hour or so is the shift change time of Jiaofan, and the patrolmen have all gone back to Jiaofan to write reports, and those who should go to work and school are also out of the house, and his crime safety has greatly increased at this time, and he is very smart."

The more Qingjian Liuli heard it, the more she felt that it was the case, and she recalled the man's attire, the inconspicuous off-white overalls, light rubber-soled shoes, and inexplicably carrying a shriveled backpack, and immediately said anxiously: "Then let's Hurry up and report!"

Takeshi Qiyuan turned a deaf ear and continued to walk forward, laughing: "This is just speculation, and I have no evidence, so I can't guarantee that this is the case. It's hard to tell the police, what if that person just has a quirk of collecting ten yen coins? Isn't that causing trouble for others!"

"Who would have that kind of quirk!" Qing Jian Liuli was in a hurry. A suspected thief had entered the town where she grew up. Don't worry, "Go and explain your reasoning to the police, maybe you can catch him. !"

"I won't go. I don't want to be late when school just started, and..." Qiyuan Wu broke free from her hand and started to enter the station directly. He turned around and smiled, "I don't need to go, someone will go."

Qingjian Liuli asked strangely, "Who will go?"

Qi Yuanwu smiled at her again and left, Qing Jian Liuli was stunned for a moment and realized - bastard, this kid thinks I will definitely go, so there is no need for him to waste time!
She really wanted to take a gamble with Qiyuan Wu, but she didn't go, to see what he would do then, but hesitated for a while, and finally dared not go into the station with him to take the tram, and turned around and ran to Jiaofan as soon as she stomped her feet.

Takeshi Qihara has no feelings for the district, but she has, and she really can't ignore it.
