The sixth man of Conan's police academy

Chapter 206 A secret code that children can understand
The rooftop of an abandoned residential building is located in a relatively remote location, and the high terrain makes the view very wide.

The fence on the roof is so low that even children can lean out half of their body.Sasashima Ritsu narrowed his eyes slightly and looked at the river they said. The distance calculated by the naked eye was 300 yards, which is quite remarkable for ordinary people.

According to what Mitsuhiko Tsuburaya said, there were four people on the roof at that time, and besides the man with the rifle, there were three gunmen. The combination of these four people was probably kidnapped with a gun.

Threaten a sniper to complete an assassination mission?He is very familiar with this kind of behavior.

Ritsu Sasashima turned to look at the three children who were looking around, raised his lips and smiled: "Children, the next thing is not suitable for you to contact. Do you need my brother to call a police car to take you home?"

Going home in a police car?Yoshida Ayumi said with a look of disgust on her face: "No, no, we can go back by ourselves."

"Yeah, riding in a police car makes it look like we are bad boys!"

"Goodbye, brother, I hope to see you catching the bad guy in tomorrow's morning paper!"

I don’t know if they were afraid that they would be sent back in a police car or something, but these three little guys disappeared in a flash.

After watching them go down the stairs, Sasashima Ritsu began to search on the rooftop. If the man holding the rifle and shooting was held hostage, there would probably be some clues left behind, and he would try to call for help even if there was little hope.

After searching the rooftop without any results, when going down the steps, Sasashima Ritsu accidentally discovered an ultra-thin calculator stuck in a rock crevice.

He took out his gloves from his pocket and put them on. He bent down to pick up the calculator and found a series of mysterious numbers written on it.

3135134112.
What is this?
It was impossible to decipher the code in a short period of time, but what was certain was that the man holding the gun and shooting was indeed threatened. This was the distress signal he left behind.

Ritsu Sasashima sighed and put the calculator into the evidence bag, put one hand in his pocket and walked downstairs quickly. It seemed that he would be forced to work overtime on his rare vacation.

He couldn't help but mutter in a low voice: "Really, why has the crime rate in Tokyo increased recently?"

After taking a taxi to the Metropolitan Police Department, Ritsu Sasashima stepped into the elevator and reached the ninth floor. He opened the double doors of the large office and walked directly towards his seat.

Hayasaka Yuna, who was not on vacation today, looked at Onizawa Takashi suspiciously and asked, "Police department, aren't you on vacation?"

"There are suspected cases of forced shooting. Most gangsters use kidnapping methods to threaten the missing people to complete shooting missions such as assassinations." Ritsu Sasashima took out the calculator in his pocket and continued: "This is a distress signal left at the scene. , I can’t figure out what it means yet, please help me check the records of missing persons reported in recent days.”

"If it had happened just now, the case would not have been filed if the disappearance had not been completed for 48 hours. I will contact the operator. They have a record of reporting the case." Hayasaka Yuna reacted very quickly and immediately picked up the landline and dialed the internal number.

Miwako Sato, who was passing by, asked curiously after hearing the conversation between the two: "Onizawa Police Department, how did you encounter such a thing?"

"Oh, when I was looking for a gourmet restaurant, I met three children. They were the first witnesses to the rifle shooting." Sasashima Ritsu replied.

"Well, you are really a responsible police officer. Many police officers will not believe what they say when they see children." Miwako Sato smiled. She quite likes this kind of police officer who is good to children. Of course, It is the kind of appreciation.

She is still a traditional type in terms of aesthetics, and she can't accept the appearance of white hair and red pupils even if she is handsome.Onizawa Takashi is like a popular anime hero in junior high school. Wait a minute... Onizawa Police seems to have a nickname in the Metropolitan Police Department recently, and I can't remember it for a while.

"Don't police officers need to have the awareness not to miss any possibility? Only in this way can the crime rate be reduced and the ability to solve cases in a short time can be reduced."

"If all police officers were like you, the police department, the crime rate would drop significantly." Miwako Sato walked to her seat, picked up the tea cup and took a sip, and asked: "Speaking of which, police department, have you not eaten yet? Lunch?”

"Let's crack this thing first and then think about lunch." Sasashima Ritsu replied, raising the calculator in his hand.

In less than 3 minutes, Hayasaka Yuna received from the operator all the recent police calls received within Tokyo, [-]% of which were missing reports but did not meet the conditions for filing a case.

After passing the screening, Hayasaka Yuna basically identified the missing person related to the case. She took out her mobile phone and dialed the mobile phone number left by the reporter. After confirming the identity of the missing person, she was basically sure that he was the person she was looking for.

"Onizawa Police Department, the missing person has been found."

"You said."

Hayasaka Yuna manipulated the computer to adjust a police officer's blue background ID photo, and said: "Through screening, I finally identified the missing person as this department police officer named Yamabe Koichi. He was a former Olympic rifle shooter. He fully meets the criteria. condition."

"Well, how did he disappear? Are there any other missing persons besides him?"

"According to the testimony of Yamabe Koichi's mother, Mr. Yamabe and his girlfriend Eri Onodera went on vacation to the surrounding area. They originally agreed to return home for dinner last night, but they did not return the phone and turned it off all night, so Yamabe's mother said Called the police at 8:10 am."

Finding out the identity of the missing person will naturally be of great help in solving the case, but what needs to be figured out at this stage is the calculator in hand.

After staring at the numbers for a long time, Sasashima Ritsu eliminated those cumbersome password interpretation methods.If Yamabe Koichi had noticed the group of children at that time, then he definitely chose the simplest way that would not be discovered by the gangsters.

Thinking of this, he couldn't help turning the calculator over, looking at the content displayed on it, he slightly raised the corner of his mouth, so that's what he meant.

Without rushing to tell the answer, Sasashima Ritsu handed the calculator to Hayasaka and asked, "Do you have any thoughts on these numbers?"

Hayasaka Yuna is not very sensitive to numbers. She shook her head and said: "There is no pattern, I can't think of it at all."

"Don't think about the logic between numbers. If you were Koichi Yamabe and only had an old calculator at hand, what numbers would you use to send out a call for help?" Ritsu Sasashima believed that he needed to teach Hayasaka some practical case-handling skills. Sooner or later she will leave the Metropolitan Police Department, so she must grow up faster.

"First of all, the distress signal must be able to decipher the mission location. Secondly, the code cannot be too obvious, otherwise it will be a big trouble if the gangsters find it." Hayasaka Yuna frowned and looked at the series of numbers and asked: "You think this 162 will Doesn't it represent a national road or a county road?"

The direction of thinking is not bad, Ritsu Sasashima shook his head and said: "Think about it more simply, it's like a code that children can understand."

"A code that a child can understand?"

Hayasaka Yuna looked at the calculator in her hand and thought of the way she used to tease the servants at home when she was a child. After she turned the calculator over, she exclaimed: "211HEISEIE!"

It seemed that she had successfully answered the question. Ritsu Sasashima put one hand in his pocket and was about to report the situation to his superiors and apply for the use of helicopters and sniper rifles. Unexpectedly, Yuna Hayasaka changed her usual image of a cold beauty and tilted her head cutely and said: "What is HEISEIE?"

"..."

　I changed my password a little bit.
