[Xiao Men Xiaosheng: Perfect crime, that is, to deal with all the details that may be discovered? 】

Zhou Yan frowned: "This, the truth is understood, but it's a bit difficult to do." ”

[The King of Appearance: Rainy day, dark night, put on a raincoat, find a remote place to kill people randomly, and never kill again]

“emmm...... As if I've heard that this kind of random target, unmotivated killing, is the most difficult to detect, but it's not perfect. ”

[TGNOHS: Induce and force the other party to commit a crime and then counter-kill on the grounds of legitimate defense]

"This is quite like that, but isn't it too difficult to achieve the operation of 'inducing and forcing the other party to commit a crime'?"

[Sea Forest Forest: If we carry tools to travel to ancient times, then it should be much easier to commit a perfect crime. 】

"Well, good idea, so, you traveled to the time before the deceased's parents got married, and messed up their marriage, is it also indirect murder?"

[Funeral Night丨Soul: A person with a beautiful surname has sinned, and he has committed a perfect crime. 】

"Shhh...... Does this book have a blocking function, is it okay to blacklist this product? ”

Zhou Yan just looked at it, but he didn't find a message that could give him ideas.

That's right, if an individual could plan a perfect crime casually, the world would have been doomed long ago.

Just when Zhou Yan was thinking wildly here, suddenly, a new message popped up.

[That's another story: the wife acts as if she is having an affair, and she often stands by the railing on the seventh floor and looks down.] Was that his mistress? The husband didn't know.

But the wife's behavior is getting stranger and stranger. The husband became more and more convinced that his wife could see her lover wherever she looked. He started looking for the guy who cuckolded him by the railing every day.

Finally, one day, the railing suddenly broke, and the husband fell from the seventh floor. 】

it?

Zhou Yan was stunned for a moment, and felt that this thing seemed to be feasible.

Do you want to copy it in a moment?

But after thinking about it again, this wife and her husband get along day and night, and she must hide her thoughts about killing her husband, otherwise before the plan is implemented, the husband will find out that his wife wants to kill herself.

Moreover, the motive can't be too obvious, after all, my husband is dead, and if I still have conflicts with my husband, it will directly attract the attention of the police.

The most important thing is that when you want your husband to lean against the guardrail, the guardrail suddenly breaks, which is not a simple matter.

You can't just sawn the guardrail, right, so just wait for the fence to rust.

But this rust time is difficult to grasp, and it may even extend to more than 10 years later, and during this period, you can't let your husband find out.

In case I waited for 9 years, but one day, my husband found that the balcony fence was a little rusty, and he replaced it with a new set of stainless steel, and the wife probably collapsed.

So, from the point of view of the technique, although it is very perfect, there are still many places outside the technique that are not easy to achieve.

That's when ......

[Arshia: Through the Nomi domino effect, create and manipulate a series of accidents to achieve the final crime. 】

"Huh?" Zhou Ya was stunned for a moment, and seemed to have a little idea.

[Xiao Jinqiu: Accident]

[Emperor Tiande: Accident! 】

"Accident? That's right, accidents are the most able to discourage detectives, and even say, it is likely that because it looks like an accident, witnesses will not call the police.

For example, a flower pot fell from the sky, and it happened to kill people.

In Zhou Yan's mind, such a picture popped up directly, probably because there was a pot of flowers broken in the office building he passed by yesterday.

It's just that the odds are too low.

Of course, it would be nice to be able to increase the odds to 100%. ”

[I'm still ██: The easiest condition for perfect crime to achieve is unconscious butterfly effect crime.]

The offender does not know that he has committed a crime, but only does something that is not illegal, and then another person does another thing that is not illegal because of this non-illegal thing, and an inevitable "accidental" event occurs in turn, forming a crime.

In the end, it was defined as an accidental event, and all the people involved got out perfectly]

"This ......" Zhou Yan first rubbed the black strip, and he didn't know why this book was always blacked out.

But this person's hint is very good.

Butterfly effect!

That is to say, to divide a person's death into many small plates, each of which is a very normal and small matter, but when they are connected together, they kill a person.

Zhou Yan closed the book, closed his fingers, rubbed his temples, and fell into deep thought.

Accident......

Butterfly effect......

Multi-person joint ......

The words swirled in his head, and eventually, they merged into a story that was all too commonplace.

......

......

On this day, it is Chinese New Year's Eve.

Miss A, dressed in beautiful clothes, is downstairs in the company, waiting for her boyfriend.

She is in a good mood, because this year can be said to be the most perfect year in Miss A's life.

First, she finally got rid of her ex-boyfriend.

That man came out of the town with him, although he was diligent and capable, but compared to the men in the city, it was really much worse.

When he first broke up, he always came to him with a dead face, and it wasn't until the beginning of the year that he found a few gangsters in a bar and beat him up, and finally quieted down.

Secondly, that's the man I'm going to see in a while.

That's Miss A's current boyfriend, handsome, young, golden, and...... Or the son of the president of this large company.

It took her boss a lot of effort to finally get into the bed of this golden boy.

Finally, and most importantly, the two of them are engaged, and the wedding is scheduled for next spring.

At that time, Miss A will have to live the life of a rich man.

It's 7:30 p.m., and it's already getting dark.

Miss A's boyfriend gets off work a little late, but after all, he is a leader, and he has more things to deal with.

After 20 minutes......

A handsome man walked out of the company's door.

"It's late!" Miss A complained displeasedly.

"I'm sorry, but today is the last day of the new year, and after the company gets off work, I need to arrange a big cleaning of the whole building, and I need to talk to the cleaning staff." The boyfriend explained.

"Okay~" A responded, before getting married, no matter what, you have to show yourself to be very generous: "I'm a little cold......"

"Then let's go to that coffee shop and have a drink." The boyfriend pointed apologetically to a small shop not far away.

This café is downstairs from the company, and the main customers are usually the office workers in the company, and the environment is very good.

"Hmm~" Miss A grabbed her boyfriend's arm and walked over.

In front of the café, there is also a Santa Claus who is quite well made, riding an elk cart, and the back of the carriage is full of gift boxes.

This was placed here the other day to celebrate Christmas.

"Let's take a picture." Miss A said coquettishly.

"Okay." The boyfriend said.

In this way, Miss A stood next to the statue and did a lot of cute movements, and her boyfriend was not impatient at all and kept taking pictures of her.

A bright point of light flies into the sky and then explodes in brilliant colors.

Under the backdrop of fireworks, Miss A even wondered if she should be kind to the man in front of her after getting married, such as learning to cook or something.

However...... Just when fireworks are rising into the sky and the sky is dotted with colors.

"Bang!"

A flower pot fell on Miss A's head.....

Along with her skull, it was smashed to pieces.

......

Falling objects, this is not a big case.

The police can only mourn for the deceased, lamenting that luck is really bad, of course, the person who caused the flower pot to fall naturally can't escape.

After a search by the police and detectives, it took almost no effort to catch a cleaner.

It was an aunt in her 40s, and it was she who caused the flower pot to fall and hit the deceased's head.

But the cleaner was very annoyed, because she had only pushed open a window at the end of the corridor from beginning to end.

Who would have thought that outside this window, there was a pot of flowers, which happened to be the blind spot of the line of sight.

When the police asked her why she wanted to open the window, she replied ...... I just heard the fireworks outside and wanted to open the window and take a look.

Well, it seems, this cleaner really didn't mean it, but ...... When a person dies, someone is responsible.

Therefore, if you cause death by negligence, you must not have run away.

But it's certainly not going to end there, and the cleaners can't just endure an unwarranted disaster.

So, she threw the blame in the face of the company again.

Because it is too dangerous to place flower pots outside the windows of such a high floor, and the person in charge of the company did not say to be careful with today's cleaning.

And in the scope of cleaning, it is also clearly written that the windows are to be cleaned.

That means that the window must be pushed open, even if the first cleaner doesn't push it open, there is a second and a third...... Is it now that conviction is like a lottery, and whoever pushes the window open is guilty?

So, in this case, the police had to ask the guilty company.

After all, the person who puts the flower pot belongs to the company, and the person who wants to clean the window is also the company, so it is impossible to put all the blame on the cleaning staff.

However, in this way, it can only mean that the company's supervision is not strict, but there is no way to put the blame on a specific person.

But if this is the case, the family of the deceased probably cannot agree, and the cleaner is unlikely to stop there.

In desperation, the police and detectives began to increase the scope of the search, and finally, in a certain surveillance video a year and a half ago, clues were found.

The surveillance video clearly recorded that a very old man put a pot of flowers on the balcony.

It is estimated that this person has the habit of raising flowers, and after this person finished putting the flowers, he was very careful and pasted a note on the glass, saying that this window is forbidden to be opened.

It's just that this piece of paper has been torn off for more than a year.

But no matter what, the culprit of the accident was finally found, so the police took this video, asked many people in the company, and finally, locked his identity.

It turned out that this person was the company's night shift security guard, which is commonly known as the "janitor".

He is an old man, in his 60s, and just a year ago, he was dismissed because he was unwell and too old.

But age is old, the flower pot you put a year ago has led to the death of a person now, so you can't not bear any responsibility for this account.

So, the police contacted the old man again.

It turned out that he had been in a coma in a hospital bed for three months due to a cerebral hemorrhage.

Zhou Yan wrote such a story with his own poor writing.

And, at the end of the story, he wrote a question......

Excuse me, who is the murderer in this case?
