The reason why the murderer ripped off the buttons was simple.

If the fluorescent paint on the button is detected by the police.

Then his murderer's identity will be exposed.

But this button also gave the police an opportunity to solve the case.

In the eyes of the murderer, the police do not yet know why the buttons were torn away.

In fact, the police already knew the reason.

This wave is that the murderer did not know that the police already knew, and thought the police did not.

The police can do something about this button.

For example, Guangyou and Conan set up a "trap".

You can investigate the buttons.

This investigation will deliberately let the murderer know.

The murderer can ignore it.

But as long as he worried that the button would be found by the police at first, he had only one choice.

Wash the buttons and put them in a corner of the apartment.

Even if the police found the button, there is a high probability that it was torn off unintentionally.

The possibility of deliberately testing is very low.

To put it bluntly, he was betting.

Gambling Guangyou didn't notice his button pulling action.

Bet the police don't check the buttons.

Even though this plan has many shortcomings and loopholes.

As long as you calm down and think, you can not enter this trap.

But how many people can keep such a sober mind after murder?

Most murderers can be described as horrified birds.

Once the police are close to the most critical evidence.

No matter how calm the surface is, the heart will start to worry.

Not everyone can remain calm in this situation.

In other words, Guangyou and Conan are also betting.

The bettor will be worried.

Bet the murderer will clear the suspicion.

...

The plan is completed.

The next step is to implement this plan and arrange the "trap".

The implementation is also quite simple.

All you need is a little acting skills to guide the murderer.

...

After they dispersed, Officer Mumu looked at the three with a serious face and said:

"Everyone, maybe you have to come back to the Metropolitan Police Department first."

"Just now we discovered that a button on Mr. Gucun's clothes was missing."

"We think this button is the key to solving the case."

"Maybe it was ripped off when the murderer had a dispute with Mr. Gumura."

"It is also possible that it is still with the murderer."

"So we hope you all cooperate."

"Come with us to the Metropolitan Police Department to do a transcript and check."

"We will say hello to the development office and it won't affect your work."

Then, Officer Megome said to Takagi:

"Brother Takagi, please take the police officers to search the apartment, the development station and the vicinity."

"Focus on checking places where things can be hidden, such as grass and trash cans."

"Yes!" Takagi Shibuya responded loudly, then turned and left the apartment.

It appears to be searched.

His confident response made the murderers present feel a little uneasy.

This trace of anxiety is like a seed.

After Police Officer Mumu said those words, he had already taken root in the murderer's heart.

At this time, the seed named "Uneasy" had already sprouted.

At this time, the murderer's heart was panic.

But he can only pretend to be calm at this time.

Like the other two, he expressed understanding of the police:

"No problem, as long as you can catch the murderer who attacked the ancient village."

...

Seeing his calm appearance, the corners of Guangyou's mouth rose slightly.

Conan, who has been observing Keihiko Negami, also breathed a sigh of relief:

"It seems that the'prey' has already taken the bait."

After putting away his smile, Guangyou said confidently:

"That's for sure."

"I never thought that this plan would fail."

"Human hearts are sometimes complicated, but sometimes they are also simple."

"If you want to make people uncomfortable, start with his weakness."

"And it can't be too direct, you have to take it slow."

After hearing these words, Conan couldn't help but sigh:

"Fortunately you are on our side."

"Otherwise it would be really troublesome."

"An enemy who can use people's hearts is troublesome to think about."

"How do you know that I am not an undercover agent?"

The words that suddenly came out of Guangyou's mouth made Conan stunned.

He reacted and shook his head and said:

"forget it."

"I still believe in you."

These words made Guangyou feel warm in his heart.

But he shook his head on the surface and sighed in a pity:

"Not fooled."

"I still want to tease you."

Conan, who didn't know this, curled his lips:

"You guys usually owe... Tucao."

"The rest is fine."

In fact, he wanted to say that Guangyou is usually owed.

But after thinking about the difference in the strength of the two, let it go.

"Tucao casually..."

At this point, Guangyou paused for a few seconds on purpose.

Conan thought that Guangyou had finished speaking, so he asked:

"Really?"

"Feel free to complain?"

It wasn't until Conan asked these questions that Guangyou continued to say the second half:

"As long as you can beat me."

"..." Conan curled his lips and stopped talking to Ricoh Yu.

...

After obtaining the consent of the three, Officer Mumu led the police and Guangyou to leave the apartment.

Police officers accompany the three suspects.

The purpose is to prevent the suspect from running away suddenly.

From a perspective that the three of them didn't notice, Conan found one of the idle police officers.

He described this plan as the arrangement of Officer Mumu.

The police officer turned around and walked to the apartment after receiving the affirmative eye cue from Officer Mumu.

After leaving the apartment building, Officer Mumu "as if" remembered something.

He looked at the three of Bu Mei and asked:

"Otherwise I will have someone take you home?"

"It's late now."

"Go home..."

The three of them looked a little tangled.

They do not know the content of the "fishing plan".

I thought that Officer Mumu was serious.

They want to watch the movie version of Masked Rider, but don't want to go back.

Usually the Ayumi trio is a bit skinny, but it's sensible when it should be.

They know that they cannot influence the police to handle the case because of their own ideas.

So after struggling for a few seconds, they are ready to respond.

The movie can wait until it is officially released.

That is to say something early and late.

Thinking about it this way, they feel more comfortable.

But perhaps seeing their reluctance, Tang Tian Jingshan asked Officer Mumu aloud:

"Mr. Police Officer, I promised to show these children a movie about Superman."

"Otherwise we go to the Metropolitan Police Department slowly."

"I'll fix the movie first, let the kids watch it first."

"If you are worried about me running, you can let people follow me."

"There is no need to worry about the safety of the children. There are still many people in the clinic."

These words caused the fire of Masked Superman in the hearts of Bumei and the three to burn again.

Their eyes are full of expectation.

In order to avoid handling the case with the police, they did not speak.

But what they didn't know was that this happened to be part of the plan.

Only when Keihiko Negami is given a chance to leave, can he proceed to the next step of the plan.

Originally, Officer Mumu was still thinking about how to give the opportunity, but he didn't expect this opportunity to be delivered by himself.

He deliberately put on a thinking appearance, and only nodded in agreement after a moment:

"Also."

"Then go to the development office first, and by the way, I will find out the situation of the investigation there."

Hearing that Officer Mumu agreed, the three Bumei people cheered in low voices with all smiles on their faces.

In addition to the three Ayumi, Keihiko Negami also secretly relieved.

As long as he didn't go to the Metropolitan Police Department, which was some distance away, he could find the opportunity to wash the buttons and put them back in the apartment.

This way he can clear his suspicion.

However, just behind him, Guangyou and Conan were looking at him with profound eyes.
