Knowing how to use elementary school students as messengers, the sender is likely to have taken the problem of the hotel's surveillance facilities into account from the beginning. Or, the sender is reluctant to show up for personal reasons. Whatever the reason, Lin Xiuyi encountered a problem.

The image of the letter being stuffed into the crack in the door was played repeatedly on the computer, and Lin Xiu read it over and over again, and finally focused his attention on the school uniform worn by the elementary school student.

"This is the uniform of that school?"

Lin Xiuyi asked in his own words.

"I don't know, but if I investigated, it would be easy!"

After Yuan Zhizhu said this, he immediately turned to look at Lin Xiuyi. Lin Xiu nodded, and then replied affirmatively to Yuan Zhizhu:

"It's not difficult, but it will take a bit of work, but as long as that's the case......"

Lin Xiuyi pulled the mouse as he spoke, and then tapped his fingers on the keyboard a few times, and then the school emblem on the chest of the primary and secondary school students and the faces of the primary school students were enlarged separately, and the originally blurry image began to gradually become clearer and clearer.

These simple technical means can be easily dealt with by using the software provided by the Metropolitan Police Department, which is not a difficult thing for the members of the search section who need to analyze evidence all year round, but the bureaucrats of the police department do not understand.

"The name of the school is Miyako City Fujiwara Elementary School!"

Yuan Zhizhu carefully recognized the words on the pattern, and then read it out carefully.

"So, we're just going to investigate this kid now, right?"

"Hey, I think it shouldn't be difficult to find him if you have a photo in hand, although I don't have any hope, but I still want to ask the person himself......"

As soon as Lin Xiu pressed the print button, several color photos containing important information slowly slid out of the printer.

Because it is now in the spring holiday period, primary and secondary schools across the country are still in the stage of vacation. So early the next morning, Shuichi Hayashi and Minamoto first visited the staff of Fujiwara Elementary School in Miyako City.

"Is this kid your student here?"

Lin Xiuyi took out the photo taken from the surveillance video from the pocket of his suit and handed it to the school staff. After the staff took the photo, they looked at it carefully, and immediately said in surprise:

"Oh, isn't this Sentaro in the third grade?"

"Is it really your students here?"

"Hey!, but the two of you are ......"

"Oh, I'm sorry, here's my business card!"

As soon as Lin Xiu spoke, he handed his business card to the other party with both hands, and after the other party took the business card, he bowed to Lin Xiuyi, and then read the content on the business card.

"Metropolitan Police Department, search section, what the hell is going on?"

The staff immediately asked Lin Xiuyi in horror.

"No, no, no, it's not that something happened to the kid in the photo, we just want to know something about him!"

Lin Xiuyi glanced at Yuan Zhizhu as he spoke, and then both of them took out their police handbooks and showed them to each other to dispel the doubts in each other's hearts.

"I see, that's the case.,It's really a surprise to me.,By the way,Allow me to introduce myself.,I'm Momoya, the math teacher here.,Sentaro used to be my student.,That's why I was so rude because I cared about it just now......"

"So, may we visit this little friend Sentaro?"

Lin Xiuyi asked Mr. Momoya.

"Of course, his house is not far from the school, so I'll take you there!"

After speaking, Momoya-sensei stood up and went to fetch the coat hanging on the hanger.

"Thank you very much!"

Lin Xiuyi also stood up and said.

Leaving the municipal Fujiwara Elementary School, Momoya-sensei took Shuichi Hayashi and Genjitake along the path on the side of the school and walked to Sentaro's house.

"Sentaro, long time no see!"

Teacher Momoya stood on the side of the road and called, and soon, a child about ten years old jumped off the climbing frame, and then ran in the direction of Lin Xiuyi and the others.

"Momoya-sensei!"

Sentaro saluted Momoya-sensei.

"Playing with it?"

"Hey!"

"Sentaro, these two police officers seem to want to know something from you, wait a minute, you have to answer the questions raised by the police gentleman truthfully!"

The little boy named Sentaro raised his head and glanced at Lin Xiuyi and Gen Zhizhu, then took two steps back a little nervously, and then turned around to run away.

Lin Xiuyi hurriedly rushed up, preemptively blocked in front of Sentaro, and opened his hands to block his way, and then Lin Xiuyi turned around, bent down and said to Sentaro:

"Do you like ice cream?"

……

Ten minutes later, at a convenience store near the park, Shuichi Hayashi placed a photo of a hotel hallway in front of Sentaro who was eating ice cream.

"The person in the photo, it should be you, right?"

As soon as Lin Xiuyi said this, Sentaro immediately stopped the spoon in his hand and looked at Lin Xiuyi with some nervousness, and after a while, Sentaro, whose mouth was covered with ice cream, nodded to Lin Xiuyi and admitted that he had been to the hotel where Akemi Sonoji was staying.

"So can you tell me where to go and what to do? ”

Sentaro stared at Lin Xiuyi expressionlessly, and after a long while, he nodded hard and admitted Lin Xiuyi's statement again.

"So, Sentaro, can you tell me who made you do this?"

Lin Xiuyi asked again. He didn't expect the boy to be able to give him as much information as he wanted, but in any case, it was better to have information than not to have it.

Sentaro looked at Lin Xiu for a long time, and then picked up the spoon and ate two bites of ice cream. Immediately afterwards, he took out a 10,000 yen bill from his pocket, unfolded it little by little with his immature little hand, and then put it in front of Lin Xiuyi.

"It was given to me by an uncle in a hat!"

"Oh, can you tell me where and when?"

Gen Zhizhu heard that Sentaro, who had been silent, was finally willing to speak, and hurriedly asked while the iron was hot.

"Just over there in the park, he asked me to help him hand over his stuff to someone very important. And gave me this note!"

"What happened after that?

Yuan Zhizhu continued to ask.

"Then I took the bus with him and went there, and he gave me his phone and told me that when it was delivered, I was going to take a picture of it and bring it to him, and I did what he said, and he gave me the money when it was done. But I don't know why, when I go shopping, adults don't want to ask for this money......"
