Tuesday, April 3, at Dr. Asasa's house.

Because the matter of going out to play was in the soup, Motota, Ayumi, and Mitsuhiko sighed and followed Ashbara and Dr. Asasa back, and then watched TV and ate the snacks prepared by Ashbara.

Gray Yuan ignored them and went to catch up on his sleep, while Dr. Asa went to the studio mysteriously.

When Ash Yuan woke up from a nap, he found a folded note at the head of the bed.

"To the detectives, I've been captured by the bad guys, go to the three places in Rice Flower Town to find out, come and save me. ”

"The first location, a five-minute walk from Didan Primary School. ”

"The second location, a 10-minute walk from Mihua Station. ”

"The third location, fifteen minutes walk from the Eastern Capital Tower. ”

"Under the converging Mizunara trees, I am waiting for you there hungry. ”

"Dr. Asasa on. ”

Gray Yuan finished reading the note softly and handed it to Motota, Ayumi, and Mitsuhiko, who were curious to hear the sound.

"The doctor looks like he's been kidnapped, waiting for you to save him. ”

"What?"

"Kidnapping?"

"How so?"

Yuantai, Ayumi, and Mitsuhiko were taken aback and hurriedly looked at the words on the note.

Ayumi hurriedly said: "Oh no, it says that Dr. Asa was captured by the bad guys, so we should call the police quickly." ”

Mitsuhiko wondered, "But, isn't it strange? Why is the message from Dr. Agasa?"

Motota had a flash of inspiration, "Ah, could it be that this is the game that Dr. Asasa designed for us?"

Ayumi reacted, patted her chest happily and said, "Great, it turned out that it wasn't a kidnapping." ”

Mitsuhiko smiled: "Ha, it's like the code game that Sister Lan and Brother Shinichi played when they were children. Then he asked, "Isn't it, Ashbar?"

"Who knows. Gray Yuan said lazily, but he gave Dr. Asa a pair of big eyes in his heart, really, he obviously walked out by himself, not to say that he was kidnapped, and he should have made a draft first if he lied.

Yuan Tai looked at the note and wondered: "But, what is it all about? ”

"Isn't there such a saying?" Mitsuhiko said with a smile, "There are still a few minutes to go, and a few minutes to go." ”

Ayumi smiled: "By the way, it's time to indicate the distance." ”

Yuan Tai said in distress: "Then how far is this?"

"Let's take a walk," Mitsuhiko said with a smile, "walk for five minutes first, and then see how far you go." Then he reacted and said, "Oh, just walk for a minute, and then multiply by five." ”

"I'll go. Yuan Tai immediately responded.

So, the four of them went to the door, Mitsuhiko looked at the time, Yuan Tai walked, and then, for the sake of accuracy, Mitsuhiko looked at the time and walked by himself.

It turned out that the distance between the two was different when they were walking.

Ayumi pondered, "What's going on?"

Yuan Tai said proudly: "It must be because of my big steps." ”

Mitsuhiko said, "Ah, then that's Dr. Agasa's step. ”

Yuan was too dumbfounded, "Then how do you measure it?"

"Well, this is ......," Mitsuhiko thought as he paced.

When Gray Yuan was about to give a hint, Mitsuhiko looked at his feet and smiled happily, "I know, it can be counted as shoes." ”

Ayumi asked, "Shoes?"

"You see, when you walk, you take a natural step, and you can probably put two shoes between your front and back feet, that is, you have walked the length of three shoes. "And the number of steps is the same, so just count how many steps you take in a minute, and then multiply them by the length of your steps, and you can know how long you have walked in a minute." ”

"I see. Yuan Tai said as if he didn't understand.

Gray Yuan secretly applauded Mitsuhiko, which is definitely a valuable performance, even if you are an adult, you may not be able to think of it.

Dr. Asa probably took the approximate number of adult walks of 80 meters per minute, which is a matter of common sense, Dr. Asasa has the common sense of adult walking, but Mitsuhiko does not.

Mitsuhiko is young and doesn't know it's not strange, but he can think of calculating the steps of adults, and find a way to calculate Dr. Asasa's steps, something that even Dr. Asasa has not calculated, this is scientific thinking and discovery.

It is precisely because I don't know that I want to find a way to know, and this process of searching is scientific research.

Gray Yuan watched as Mitsuhiko and the three of them measured Dr. Agasa's shoes, and then measured the cadence of the three of them, and then had a headache because the cadences of the three were different.

Seeing that they really had no choice, Gray Yuan reminded them to take an average, that is, to add up the cadence of the three people, then divide it by three and round it, and took the calculator and gave it to them.

Ayumi asked, "How do you use this?"

"I know this, my mother uses it every day to settle accounts, and she taught me. Yuan Tai said proudly, "If only I had brought a calculator for the exam, I'm sure I'm all right." ”

As he spoke, Motota calculated Dr. Agasa's one-minute walk, and then, at the urging of Mitsuhiko and Ayumi, he calculated Dr. Agasa's five-minute, ten-minute, and fifteen-minute steps.

Ayumi asked, "But, how are we going to go?"

Mitsuhiko said, "You can look at the map, now you just need to know the places on the map." ”

Yuan Tai asked, "Gray Plains, do you have a map?"

"I guess there is. "Gray Yuan took them to Dr. Asasa's studio, and sure enough, they found a map of Rice Flower Town, with eraser marks on it.

Ayumi pretended to be angry and said, "Hmph, in this way, it was really written and directed by Dr. Agasa." ”

Yuan Tai nodded and said, "That is to say, it makes us worry, and we must invite him to dinner." Then he asked, "But the map is so small, I walked over it in two steps......

Mitsuhiko couldn't help but laugh, "There is a scale, this map is 10,000 to 1, which means that it will be 10,000 times smaller." ”

"I see. Yuan Tai said with a dry smile.

After delineating the three locations, Ayumi measured with a ruler and found the place, probably in Rice Flower Park, because there is a big Mizunara tree in Rice Flower Park, but for the place to find, it always feels like it's a little bit worse, and it seems that it doesn't know the point.

Mitsuhiko looked at the tools on the table, picked up the compass, and drew three circles on the map according to Dr. Agasa's steps.

A five-minute walk from Teidan Elementary School, a ten-minute walk from Rice Flower Station, and a fifteen-minute walk from Dongdu Tower, the intersection of the three circles is exactly in Rice Flower Park.

Ayumi asked, "It's amazing, what is this?"

Mitsuhiko smiled: "This is a compass, I see my sister has used it." ”

"Okay, let's go to Rice Flower Park!" shouted Yuantai.

"Oh!" Ayumi and Mitsuhiko echoed. ……

Soon after, Rice Flower Park.

The four of them found the park manager under the Mizunara tree in Rice Flower Park taking down an umbrella hanging there from a branch and wrapping it tightly.

The park ranger took a look and read out a set of katakana on the bottom end of the umbrella handle.

The four of them listened to him read it back and forth, and finally understood that it was Asasa, Dr. Agasa's Asasa.

Ayumi and the three hurriedly went to ask for an umbrella, and Gray Yuan was speechless again, Dr. Asasa's game design is really incomparable to the designer of the game when Kudo was a child.

Everyone puts it where children can reach it, but Dr. Asa is good, and he uses the steps of adults and puts them on branches that only adults can reach, which is really sloppy.

Ayumi and the three of them were about to get the umbrella, and when they opened the umbrella cover, they found that there was a loop of plastic sheeting wrapped around the umbrella body, and when they took it off, they found that it was a long plastic sheet, and there were many katakana on it.

It's just that the three of them can't read left and right, and they can't read it.

Ayumi had an idea, "By the way, this strip of cloth is wrapped around the umbrella, do you want to wrap it back?"

Ayumi tried it, and wrapped it all in a circle, but it still didn't seem to be able to read, so she went around and lined up all the katakana neatly, and it turned out to be read, and it was the Rice Flower Library.

Gray Yuan secretly applauded Ayumi, the code stick of Sparta in ancient Greece, was just done by the little girl, is it said that those muscular men only grow muscles, not heads?

However, the muscles are still very beautiful. ……

Soon after, the Rice Flower Library.

The front desk librarian asked for the names of the four Gray Plains and handed them a letter, an unsealed letter with Dr. Asasa on the envelope, addressed to the Junior Detectives.

The four of them looked at it, and inside was a letter with a lot of blanks, a crossword puzzle, and then according to the different spellings in the colors, they put together the katakana filled in the red blank space.

The gist is what I am, what I look like, 53 years old or something.

What is Dr. Asasa, Ayumi, Mitsuhiko, and Motota have a lot of discussions on this issue.

Genius, famous, rich, celibate, poor, stubborn, short-sighted, presbyopia, handsome, round face, big nose, clumsy.

The three of them laughed amusefully.

Gray Yuan said angrily: "Okay, when are you going to get it? stop joking, and finish the matter first." ”

Mitsuhiko smiled, "But you have to think about it in turn." ”

"No matter how much you think about it, Dr. Asa won't say he's stubborn or anything. Gray Yuan looked around at the three of them, "If you can't agree on the opinions, let go of it first and continue." ”

Ayumi said, "The appearance is that of an old man. ”

Yuan Tai smiled evilly: "Old man." ”

"Yes. Mitsuhiko echoed.

"Huh?" Gray Yuan faced each other coldly, and Yuan Tai and Mitsuhiko suddenly changed their words, and they looked like grandfathers.

And in the last place, the three of them agree on the same opinion, which is the tone particle.

In the end, by the grandfather and the mood particle,Spelled out is じんじゃ,That is, the shrine,Rice flower shrine。 ……
