"Dangdang." Mizumatsu knocked on the door lightly, and no one answered inside.

"Duang, Duang, Duang." After using some strength to knock it again, no one responded.

Three black lines flowed down Shui Jianyue's forehead and knocked them three times hard, just like he swung his fist and hit them three times.

"Bang, bang, bang!"

Just when Mizumatsu suspected that the person inside had already escaped or committed suicide fearing guilt, Yoshimichi finally opened the door, and the headphones wrapped around his neck and music were revealed, explaining why its owner had not heard the knock on the door for a long time. Yueshimichi tilted his neck and looked at Mizumatsu with a cute look on his face.

Music is English songs and bass.

In Hattori Heiji's room, Hattori Heiji rode backwards on the chair, looking at Conan lying on the bed bored: "Worker...ah...who, who, what do you think that person is doing now?"

"Let me think about it..." Conan shook his legs one after another: "I think he must be doing things related to his interests."

"Huh? Shouldn't you be constantly sorting out your actions and have you omitted it?" Hattori Heiji had a different opinion on Conan's view.

"That's all stupid thieves." Conan beat Hattori Heiji to the stupid thieves with one shot: "I think since I'm a detective, I should try my best to calm myself down and not let people see my emotional differences. Since I can't participate in solving the case, I will try my best to show my indifference to the case. If it's me, I will definitely play football desperately."

In Yueshui Qikui's room, Yueshui Qikui looked at Mizumatsu with dissatisfaction: "What are the police officers doing again? Is there anything else to ask? Could it be that I want to check my luggage again?" Speaking of this, Yueshui Qikui looked at Mizumatsu as if he was a hooligan.

"We will talk about whether to check the luggage or not. First of all, I have some questions to ask you about your wisdom as a famous detective in the south." Mizumatsu smiled.

"So, I really want to turn over the girl's luggage." Yoshimizu Nanao looked at Mizumama with contempt.

Even though he knew that this was a psychological tactic that Yokosuke did on purpose, Mizumatsu was still amused and couldn't do it even if he wanted to be stern, so he had to wave his hand: "It's better to be a serious business."

"Okay, okay, but the police officer who was disgusted with the detective just now came so quickly to seek wisdom. What should people evaluate it?" Yoshimizu Nanao looked at Mizumamatsu sarcastically.

"What do you think?" Mizumatsu looked at Yueshui Qikui with fun, which made Yueshui Qikui feel furious.

"Please say it." Yoshimizu Nanao said honestly.

"From the blood we found on the scene, the victim's blood should have squirted the murderer's body, but none of them in the mansion were wearing blood clothes, how can I solve it?" Mizumatsu asked solemnly, and it was also the biggest card that determined the identity of the murderer.

"This is not simple. You just need to wear a raincoat or other equipment to block the blood. Then it is very convenient to discard or clean the blood." Yukishui Qiqiu, a police officer, hasn't you ever handled the case?

"But the deceased is also a well-known detective, so he naturally knows this truth. Since he is hit by the back of his head, it means he is not prepared for the visitor. If the visitor is wearing a raincoat, he will be more alert, right?" Mizumatsu asked again.

"I don't know this. Maybe the murderer is not between us and is still wandering somewhere outside the mansion?" Yoshimizuki's tone seemed to be telling a midnight ghost story at a pajama party.

"My personal idea is, will the murderer change his clothes after killing the person?" Mizumatsu said seriously, as if he was really asking for advice from Yueshui Qikui.

"You have a good idea!" Yoshimichi snapped his fingers excitedly: "I, Black Lord, and all the fake directors have changed their clothes, but because of the need for Black Lord and I on the show, the only fake guy put the wine on the clothes and went back to his room to change clothes!"

"But it's not necessarily the one who has been killed and then changed clothes." Yoshimizuki changed the subject: "Maybe you can change your clothes first, and then kill and then change them back. In this case, we have never seen it in the kitchen. It is very likely that Mr. Kagu, who has a lot of time, is also the one named Baima. He said that the school he studied abroad does not have a school uniform, but does anyone actually know? Maybe he changed his school uniform and went to find Shizu Junya. The two of them had a quarrel and they were passionate about killing people. He thought of a way to cover it up and then changed the clothes back. In this way, your task will be much heavier if the officer!" Yoshimizuki's expression was completely gloating.

"But at least it means there is a bloody coat, is that right?"

"No matter where you are hidden, you can find it. Find your luggage first. If you can't find it in the luggage, look for it in the mansion."

"As long as the murderer is a person in the mansion, he will not have the opportunity to dig a hole in the depths of the uninhabited island outside and bury his bloody clothes. He can arrive here sooner or later."

"Are there many detectives here? It's good to cross each other and help search. The detectives always know more about hiding things than the police." This sentence is considered to be a clear statement that the murderer is a detective.

As Mizumatsu finished speaking, Yokomi's smile frozen little by little.

"It seems that the police officer of Mizuma thinks I am the murderer. Can I ask why?" Yoshimizu Nichiko asked clearly.

"First of all, you are lying about your age. Although the people here don't know you, you can actually know whether you are a high school student. Detective Jiaziyuan should not invite you from the beginning, unless you are the murderer's target, or you are the murderer. After applying this view, the hammer found behind the kitchen sewer and the screw tail under the window of Hirosaki Hirosa will feel a strong feeling of scapegoat." Mizumatsu shook his fingers.

"If I add a sentence after my age is exposed, the organizer cannot find a high school detective of the right age in the south, so I hope that I will replace him who has just graduated, will the suspicion be reduced?" Yoshimizuki smiled bitterly, his ability to adapt to the situation is still not enough.

"Who knows, there is a second doubt anyway." Mizumatsu stretched out his second finger: "In order to create the mystery of the program and catch the detectives off guard, the contestants did not give the contestants a rough schedule before the so-called program started. But you who had already thought that the Jiaziyuan project should wear school uniforms and chose to bring their clothes to the island to change."

"It's easy to say about the rest of the people. Because the school rules are complicated, you need a lot of time to organize your school uniforms. Are you not afraid of starting the program recording as soon as you go to the island?" Mizumatsu asked one by one.

"Because this time is arranged in this way, I deliberately left the time for that bastard to show off, set up my own death room, and then calmly change my clothes after killing him. Police officer, do you think so? But what about the evidence?" Yoshimizuki was like a disguised confession that he had committed the case, but without evidence, he would not plead guilty.

Mizumatsu turned his head and looked at the large suitcase of Yokosui, which was very obvious.

"Okay, okay! I'll open it for you!" Yueshui Qiqiu looked impatient and walked to the front of the suitcase and opened it.

‘How come I’m like a perverted uncle…’ Mizumatsu smiled bitterly by Yueshui Qikui’s appearance.

"Here, this is the clothes I wear. If you don't believe me, please ask others." Find out the clothes I had in the morning, Yokosui Nishiki gave it openly to Mizumatsu.

The hand with gloves took the clothes, and Mizumatsu wrinkled every day: "Why is it a little wet?"

"Can you get wet in the rain? There is no place to dry clothes, so I don't want to spread it on the bed, so I have to stuff it inside first." Yueshui Qiqiu looked like you were fussing.

"Do you mind?" Mizumatsu turned magic and had a small bottle of rumino spray can in his hand.

"This thing is not easy to wash, right?" Yue Shui Qiqiu smiled and muttered in a low voice, then gave up: "Whatever you want, do whatever you want!" As he said that, he waved his hand like a flies.

Scream—Shui Jianyue sprayed the lumino reagent without hesitation.

"What the hell!" After spraying the reagent, it was neither a proven innocent nor a reflection of the mottled traces of the crime, but the whole piece of clothing emitted a strong blue fluorescence.

"What did you do?" Mizumatsu should have been a little angry, but he was a little helpless and asked weakly.

"I did nothing! By the way, I remembered that when I was washing clothes, I like to use some bleach, maybe it was because of the residue of bleach. Don't you know? In addition to reacting with hemoglobin, luminol reagents can also react with elements such as copper and iron, and bleach with strong oxidation properties, so let's get some accurate things in the future! Don't blame any innocent people anymore." Yoshimizuki's frowning face just now disappeared, replaced by a prank-up smile.

"Haha, you are good at chemistry. Then this dress will be sealed by the police for a week and will be returned to you after the identification is completed in a week." Mizumatsu didn't understand what she was proud of.

"What does it mean... Oh! How could there be such a person?" Yue Shui Qiqiu's face was like a change of face. It dissipated as soon as he became proud, but he still didn't forget to pretend that Mizumaki just took away the girl's clothes and did something vulgar...

"Oh, you won't know, right? The bleaching powder will disappear after three to five days, and the blood can still be detected at that time. If it is tested in the police laboratory, you will not be wronged. It should be blood or blood, and if it is something else, it will not be said to be blood." Mizuki still looked weak, but cut off the last move of Yueshui Qikui.

Feeling that all the strength in his body disappeared, Yokosuki collapsed on the bed regardless of his image, complaining: "Why do you know so clearly that's the same policeman?"

"Oh? So my colleagues in the south are confused about handling cases." Mizumatsu asked casually.

"It's not the south, it's the north, the sluts of Shikoku Island." Yokomizu Nanao began to tell a story from a long time ago.

Of course, the story told by Yokosui was her motive for the crime. Generally, Mizumatsu never had any interest in listening to this kind of content, but perhaps the story involved the police, so Mizumatsu did not stop her, but quietly listened to her story.

There is also the case of hiding corpse in the temple a few days ago. Mizumatsu also curiously listened to the old monk's motive for hiding corpse. Maybe he can only say that people will really change slowly.

After Yoshimizuki finished speaking, Mizumaki remained silent for a long time and said, "It has been a long time since the incident, and your friend's case may not be able to be identified anymore. However, if Hirotoshi O confesses that there is still a chance, at least I can do it. Maybe I will only apologize to you and your friends for my colleagues in the Four Kingdoms. I'm sorry." Mizumaki apologized to Yoshimizuki solemnly.

"Take me away." Yoshimizuki stretched out his hands and was waiting to be handcuffed: "I'm thinking now that you, a policeman who firmly eliminates the influence of detectives and only believes in his own judgment, may have many advantages."

"Hey, as long as I'm still in the job for a day, the case I handle will never let the detective make trouble." Mizumatsu raised a confident smile.

———————

Back on the ship on the land, Mizumatsushi recounted the cause and consequences of the case to the police, and Conan also listened.

"Okay, I'll ask you, what experience did you learn in this case?" Mizumatsu started the exam.

"Well... I'm fine-dividing the labor according to the importance and workload when there is insufficient staff?" Shiragou naturally had to be the first to answer as a police department.

"Good to exercise your brain?" Sen also replied. He felt that he had made contributions to the bloodstains to attack the murderer.

"Attention to the weather at any time?" Kato Kuma Nobu was shameless and messed up.

"All wrong!" Mizumatsu said with a hint of excitement: "This time the case handled, tells us that the detective will also handle the wrong case! The detective will also be the murderer! So no one is allowed to give me superstitious detectives, do you understand?"

"I understand!" The police wanted to laugh a little, but Mizumatsu looked too serious and dared not laugh.

"Puff." Conan, as a (former) detective, laughed out loud.

Mizumatsu is a policeman who hates detectives very much, and it may never change things.
