"It looks like it's radio-controlled." Mitsuhiko Tsuburaya said.

Kojima Motota asked curiously, "Where did you manipulate it?" ”

"Bang!" A sound appeared, directly bursting the balloon tied to the motorboat toy.

"Huh?" "Huh?" "Huh?" The sudden change made the three members of the Junior Detective Group a little confused.

"It's gunshots!" As soon as he heard the sound, Conan immediately knew that it was a gunshot, and quickly took out the binoculars on his body and looked towards the building in the distance. There were four people at the top of the building, one of whom was crouching with a gun in his hand. "It's rifle!"

"Huh?" The remaining three couldn't help but exclaim.

"I saw it, right there, there's someone in the building on the other side." As he spoke, Conan saw the man with the gun suddenly turn his head to look at this side, paused, and turned to leave.

"They're gone!" Conan said as he lowered the telescope.

Kojima Motota immediately said: "Then let's hurry over and see who is using the lucky gun to shoot." ”

Mitsuhiko Tsuburaya said approvingly: "That's right, that's right, let's go and have a look." ”

"Don't worry!" Stopping the two who were about to run, Conan explained to them, "To go is to go, but we have to wait and go again, otherwise if they are bad people and we run over, won't they be caught?" ”

"Conan is right." Hearing this, Mitsuhiko Tsuburaya nodded and said, "Let's go over later." ”

"Okay!" Although a little unhappy, Kojima Motota agreed with them.

After waiting for about 10 minutes, Conan said, "Let's go, let's go now." ”

The next group of four people ran towards the building on the opposite bank, and after about ten minutes, they came to the top of the building.

"Hey, it looks like it's really shooting over here." Kojima Motota came to the edge of the guardrail and looked towards the river, but he could see clearly where they had been.

"If that's the case, then the technology is really amazing." Mitsuhiko Tsuburaya said in surprise.

Ayumi Yoshida asked Conan beside him, "Is that person making contact with shooting?" ”

"Maybe it's a test." Conan babbled to himself, "And it's a compulsion. ”

"Compulsive?"

"Hmm!" Conan nodded and said, "I just saw two men with pistols pointed at that man." As he spoke, he lay on the ground and looked around.

Ayumi Yoshida asked curiously, "What are you doing?" ”

"I wonder if there's anything to be evidence of." Conan replied, in fact, he was wondering if the man would leave anything behind. If anything, it was probably what the man was trying to say.

"Then we'll help find it too!" Motota Kojima, Mitsuhiko Tsuburaya and Ayumi Yoshida said and followed Conan's example, lying on the ground and looking carefully.

The platform on the roof of the building was not very big at all, and the four of them quickly searched for the roof, but found nothing.

Finding nothing useful on the roof, Conan couldn't help but walk down the stairs, observing carefully, not as anxious as he had come.

"Huh?" The hard work paid off, and finally Conan dropped something under the broken stones, and then carefully took out a white handkerchief and carefully held it in his hand.

"Calculator!" Kojima Motota, who was walking behind, saw that it was a calculator, looked at the numbers on it, and couldn't help asking, "What are those numbers?" ”

Sitting on the stairs, Conan muttered, "I wonder if the man wanted to tell us something, but he didn't have any other way to leave a message, so he left these numbers and replaced them with numbers?" ”

Mitsuhiko Tsuburaya pondered, "But what message does he want to leave behind?" ”

"I don't know yet." Conan shook his head, and then said, "Anyway, we need to inform Officer Twilight first." ”

Hearing this, Ayumi Yoshida said loudly: "Conan, let's inform Brother Yamamoto, and we can ask him to invite us to eat when the time comes." ”

"I agree with Ayumi's suggestion, let's inform Brother Yamamoto, and let him invite me to eat eel rice when the time comes." Kojima Motota immediately agreed.

"I agree!" Mitsuhiko Tsuburaya happily raised his hand in agreement.

"You guys!" After listening to the words of the three of them, Conan could only helplessly take out his mobile phone and dial Yamamoto's number. "Hey, Brother Yamamoto, I'm Conan, and I have something to tell you here. Here's the thing."

"Well, okay!" Conan answered, and after hanging up the phone, he said to a few people: "Brother Yamamoto said that he will come over in a while, let us wait for him here." ”

"Great, we'll go to a big dinner in a minute!" Motota Kojima, Mitsuhiko Tsuburaya and Ayumi Yoshida cheered happily.

"You guys!" Conan shook his head helplessly, turned to the calculator in his hand, and fell into deep thought.

More than half an hour later, Yoshitsuru Yamamoto drove his car to the abandoned building. After receiving a call from Conan, he left the office and hurried over.

After reaching the top of the building, Yamamoto Yoshitsuru, led by the four little ones, came to the guardrail, looked at the reeds in the river and said, "You mean that someone here uses a lucky gun to shoot moving balloons, right?" ”

Conan nodded and said, "That's right, after the balloon burst, I saw it through my binoculars, and the man was holding a rifle in his hand. ”

Yoshizuru Yamamoto squatted down, made a gesture of shooting with a lucky gun, and then said, "Isn't that what it looks like?" ”

Seeing his movements, Conan thought about it, nodded and said, "That's right, it's Brother Yamamoto, you are like now." ”

"Looks like this guy's shooting skills aren't bad!" Yoshitsuru Yamamoto stood up, patted the dust on his knees, and said to Conan, "What about the calculator you said?" ”

"Here." Conan said as he handed over the calculator in his hand.

"Huh?" Yoshitsuru Yamamoto, who was about to get the calculator, stopped what he was doing, motioned for Conan to put the calculator on the ground, and said to him, "If you come to me, you might find something interesting." ”

"Something interesting?" Conan ran over puzzled, looking at the reversed calculator, his pupils shrunk slightly. "This is this"

“291，heiseie！” Yoshitsuru Yamamoto read the numbers and letters on the calculator word by word and said, "It seems that this is the message that the man wants to leave us." Even if the calculator had been discovered by the inmates, they would probably not have understood what it meant. ”

"Hmm!" Conan nodded in agreement and said, "The message left by that man must be this, but what does this mean, you still have to think about it carefully." ”

Picking up the calculator with Conan's white handkerchief, Yoshitsuru Yamamoto said, "Now that I know the number, I'll send the calculator to Officer Twilight, and ask him to scan the fingerprints left on the calculator to find out who that man is." ”

"Then it's troublesome for you, Brother Yamamoto." Conan nodded, this is also a solution. Maybe finding out the identity of that man will help things go well.

Kojima Motota said loudly: "Brother Yamamoto, you want to invite us to a big meal, this is what we found." ”

"No problem, I'll take you to a big dinner right now!" Yoshitsuru Yamamoto responded with a smile, dealing with this child, there is no shortage of food. As long as they eat and drink well, they will still call themselves next time they have a case, and the investment will pay off!

"Okay!" Motota Kojima, Mitsuhiko Tsuburaya and Ayumi Yoshida cheered happily.

Leaving the abandoned building with the Junior Detective Corps, Yoshitsuru Yamamoto first took their things to the car, and then took them to a high-end conveyor belt sushi restaurant to fill them up. Mitsuhiko Tsuburaya, Ayumi Yoshida and Conan ate less, but Motota Kojima's amount alone was no less than that of the three combined, and the plates in front of him were piled up in a few piles.

After paying the money, Yamamoto Yoshitsuru took the four of them out of the sushi restaurant and said to them: "Brother Yamamoto is going to the Metropolitan Police Department next, so I won't take you there, you can go and play by yourself." ”

"Metropolitan Police Department!" Kojima Motota touched his stomach and said, "Brother Yamamoto, you can take us with you, okay?" ”

Ayumi Yoshida also said: "That's it, Ayumi also wants to go to the Metropolitan Police Department to play." ”

Stretching out his index finger and shaking it at them, Yoshitsuru Yamamoto said with a smile: "No, there has been a case of jewelry theft recently, and the Metropolitan Police Department is very busy, let's not bother the police officers, okay?" ”

"Okay!" Ayumi Yoshida nodded, and then said, "But Brother Yamamoto, you will take us next time." ”

"If I have the chance, I will definitely take you there." Yoshitsuru Yamamoto smiled and nodded, then took out their things, said goodbye to the four of them, and drove towards the Metropolitan Police Department.

When I arrived at the Metropolitan Police Department and parked the car, Yoshitsuru Yamamoto had just gotten out of the car, but he saw an acquaintance.

Naeko Ikeda, who had just gotten out of the police car, was about to leave, but when she saw Yoshitsuru Yamamoto, she was stunned for a moment, and then walked over with a sneer. "Mr. Yamamoto, long time no see!"

"Miike, long time no see." Listening to the name of the beautiful woman in front of him, although Yamamoto Yoshitsuru didn't know where he offended her, he still smiled and said hello.

"Humph!" Michimiao snorted coldly and said unhappily: "Can Miike also be called by you?" I don't seem to know you very well, do I? ”
