On Sunday, Conan and the Young Detectives were playing at Dr. Asasa's house, when the phone rang at Dr. Asasa's house, and Dr. Asa picked up the phone.

"Hello, is it Dr. Agasa? I'm Mizumatsuki, the head of the Tokyo Metropolitan Police Department's Investigation Section 1 and 3 Division, and I have something I would like to visit you, is it convenient for you today?"

"Hm...... Convenient." Dr. Asa was a little confused when he heard this, and he agreed casually.

"Okay, I'll be there around three o'clock." Mizuma hung up the phone without saying a word, not giving Dr. Asa a chance to change his words.

"What's wrong, Doctor?" Conan noticed that there was something wrong with Dr. Agasa's expression and asked. There was a police officer named Mizuma Tsuki who said he was coming to visit......" Before Dr. Asa could finish speaking, the Young Detectives group shouted in unison.

Ayumi: "Officer Mizuma, is that the one who criticized us last time?"

Mitsuhiko: "That's the bad-tempered police officer!"

Yuantai: "It's scary, let's run!"

In this way, the Junior Detective Group was intimidated by Mizuma Tsuki's murderous reputation, and disappeared without even saying goodbye to Dr. Asasa.

Dr. Asasa: "Well, the officer said he'd come at three o'clock in the afternoon, so they could stay and play a little longer and have lunch before leaving."

"Hehe, Officer Mizuma is terrible for them." Conan was also helpless, "Speaking of the last Shinkansen bombing, he said he wanted to talk to you about child safety, but he never mentioned it, I thought he forgot, I guess this is for this."

"Eh, Shinichi, haven't you heard of that?"

"yes, I'm the one who probably forgot." Conan touched his head and said with a dry smile.

"Shinichi, you're a reflection of irresponsibility......

At three o'clock in the afternoon, Mizuma rang the doorbell punctually, and Dr. Asa opened the door and invited him into the room, where Conan sat on the couch - he tried to walk, but Dr. Asa forcibly detained him.

Mizuma didn't rush to the point, "Hello Dr. Asasa, I heard that you are a very famous inventor, so I took the liberty to visit today, please bear with me." ”

Dr. Asa is a little like Maori Kogoro, once he is praised, he gets carried away, touches his head and laughs: "Where, where, I'm just a little famous in a certain circle, hahahaha~"

"How so, your invention is very epoch-making...... Let's ......."

"Officer Mizuma, you're really a delusion...... Let's go, let's ...... it's like this, Mizuma Moon and Dr. Asa had a cordial and friendly conversation, and Conan on the side stared at the dead fish eyes, and complained in his heart: Hey, where is the momentum you roaring at me?

Chatting and chatting, Mizuma slowly cut to the chase: "Dr. Asasa, I went to the Inventors Association before I came, according to the information of the Inventors Association, your research project is a mechanical insect flight model, but from Conan's inventions, it seems that your invention direction has little to do with mechanical insects, right?"

"Well, because the invention is in a bottleneck, I just studied something else and changed my mind......" Dr. Asasa laughed dryly, but fortunately Shinichi guessed that he would ask such a question, and asked Dr. Asa to prepare his words in advance. "Oh~ That's right, so you're really powerful, it's just a 'change of mind', but you've invented so many powerful things. As he spoke, Mizuma looked at Conan on the side. "I remember that Conan had a bug and a signal transmitter on his glasses, right? And his bow, it looks like a voice changer, right? Don't you know, we also have a voice changer in the Metropolitan Police Department, but that thing is bigger than a Coke can, how can it be so convenient like Conan! There is a tranquilizer gun on the watch? Oh, our Metropolitan Police Department's tranquilizer gun is as big as a shotgun, I don't expect it to be as small as a watch, and I can be satisfied if it can be reduced to a pistol, really! Look at Conan's ...... It's called Foot Strength Enhancement Shoes, right? Amazing, I guess all the bullets in my gun are out, and I can't even kick Conan, right? Tut-tut, the body of the Shinkansen train can hit a hole. Doctor, you are so powerful at inventing things 'casually', and you say that Doctor, you are not a great inventor, Doctor, you are so modest!" Mizuma Moon spat out a series of compliments like a machine gun, and Dr. Asa was confused when he heard it, unable to distinguish whether to praise or sarcastically mock himself, and only broke out in a cold sweat.

"By the way, do the children of the Junior Detective Corps have such dangerous equipment?" Mizuma asked sharply.

"No, no, only new ...... Ah, Conan, only that!"

"No, no, only me!" Dr. Asasa shook his head in fright with Conan, and Dr. Asa was so frightened that he almost slipped out.

"If it's just Conan, then I'm a lot more relieved. Mizuma said in a very gentle tone, "After all, Conan is a very 'mature' 'big' child. Mizuma read the words 'mature' and 'big' very heavily, which made Conan and Dr. Asasa feel a surprise in their hearts, wondering if he meant something else.

"Ah, it's not too early, I should take my leave. Mizuma Yue glanced at the time, it was already time to eat, stood up and said.

Dr. Asasa symbolically retained, "Yuejun can stay and leave after dinner." ”

"Really, can I stay and have dinner with the Doctor?" Let Conan and Dr. Asa shout in their hearts that this person is cheating.

Then Mizuma changed her expression again: "Just kidding, just by looking at Conan's expression, I know that he wants me to stay away! I'm leaving!"

Before the old and the young could react, Mizuma leaned in half of his body again: "By the way, I think it's better for Dr. Asa to register these inventions, so that others can 'rest assured' and not make people 'suspicious', right?" and really left.

"That's right!" Dr. Asa slammed his fist into his palm, breaking the dead silence between him and Conan.

"If I submit these inventions, if those people in the Black Order notice the inventions on you, they will just think that I gave you the inventions to make toys and don't think much about it. If you don't, the Blackcoats will notice you when they see you, and they'll investigate you, and then ......" Dr. Asa made a look of horror and then excitement.

"In this way, Xiaolan won't take the initiative to think in the direction of me Shinichi when she sees me using props!" Conan, who was full of girlfriends, was also excited, and then frowned again, thinking: "Did that Mizuma Moon say this unconsciously or deliberately remind us?"

"yes. Dr. Asasa nodded, "It's really strange that Officer Mizuma said that, and that sentence seems to mean something. "He's worried about the 'mature big kid'.

"Speaking of which, he seems to be a very good person, yelling at you because he was worried about your safety, and he took you to the hospital last time, why did he throw you out of the crime scene every time?"

"I don't know......" Conan replied absentmindedly, remembering that the last time he met the Italian bandit group, Mizuma Tsuki said 'Seventeen' as if he had made a slip of the tongue, and the next time they met was at the time of the Shinkansen bombing, at that time......

Conan suddenly remembered something and said to Dr. Asasa, "Doctor, can you help me find out the 'police officer who hugged his head and cried at the scene'." ”

"'The policeman who hugged his head and cried at the scene'? What is that?" Dr. Asasa looked puzzled.

"I don't know, but it seems to have something to do with the moon between the waters. Conan remembered that in the Shinkansen case, there was a Kyoto prefectural police department who used this word to mock Mizuma Tsukirai.

"Then I'll look it up. Dr. Asasa walked into the back room and began a complicated internet connection. At this time, the Internet technology was not perfect, and it was necessary to plug the telephone line into a converter, and then connect it to the computer for a virtual dial-up connection.

After eating, Conan and Dr. Asa got together in front of the computer and began to search for information, which soon locked on to a piece of news.

"Shinichi, this seems to have something to do with you, right?" said Dr. Asasa uncertainly.

The news is about a case that was solved about a month ago, when Kudo Shinichi had not yet become Conan, and there was a policeman squatting by the wall at the scene of the crime, holding his head in his hands, as if he was in pain. A reporter from a small newspaper found him and took a photo and named it 'Police Officer Crying with a Head at the Scene of the Crime'.

"Doctor!" Conan seemed to have discovered something, and asked Dr. Asasa to "enlarge this officer!

As the image zoomed in, Conan and Dr. Asasa's eyes widened, and although the image was blurry, it was easy to see that the police officer was Mizuma Tsuki who had just left here!

"Well, Shinichi, what the hell is going on?" Dr. Asasa asked, scratching his head, saying that Dr. Asasa did the most today was to scratch his head.

"I don't know, although Mizuma Moon is not very good at reasoning, but he is also a very capable and methodical police officer, I still have an impression of that case, there is no difficulty, and he is the kind of person, he just can't think of being preempted by me, and he shouldn't cry, right?" Conan was also puzzled, and analyzed it a little bit: "And this action doesn't look like crying, from a behavioral point of view, it's more like holding your head because of severe head pain, is it being beaten?" It's not right, on the occasion at that time, the first reaction to being hit was of course shouting. ”

"It seems that there is only one truth. Conan said with a sigh.

PS You beasts are too capable of water building, and you will never play like this next time...... No, you are not beasts at all, you are aquatic products at all!
