How can people who live in three places communicate across hundreds of kilometers?

In an instant, a lot of ideas popped up in the minds of a few policemen.

"Network!?" Zhang She suddenly spoke.

In the past two years, network technology has sprung up like mushrooms after a rain, and the development speed is comparable to the big bang!

Penguin: Almost everyone who has a computer will sign up for one!

The post bar is also, now is the hottest time for the post bar, and the highest number of online people in prime time is as high as 10 million!

In this case, if the murderer and the victim are very familiar netizens, then it is also possible to make an appointment during the festival and then kill.

But.....

"First of all, if a party can ask netizens out, then, the two parties are likely to be of the opposite sex, not the same sex, but the identity of the murderer in the video is very obvious, and it is very difficult to make an appointment with four victims at the same time."

"Of course, if the murderer used the identity of the opposite sex to deceive people, it is possible." Xu Hao said.

He had heard a rumor that when Penguin was first launched, a certain juvenile boss was trying to solicit customers......

Hanging a female avatar, a strong flirtatious man in front of the computer.

"But I just said it."

Xu Hao put away his thoughts, and he spoke:

"The trait that the murderer wants is the victim himself! and not a certain characteristic, including but not limited to 'talking', 'fetish', 'psychological personality', etc.! ”

"Do you think the murderer can understand the victim himself through the screen?"

"No, netizens are netizens after all, and most of the emotions shown on the Internet are likely to be false, how can the murderer know the victim."

Xu Hao spoke, the Internet and reality are two channels after all.

How can you get to know each other through a few chats across the Internet?

At the beginning, he saw a shy person with some low self-esteem, but the Internet is very unrestrained and interesting, this contrast is not clear to netizens.

"What if the murderer plays a woman and then brings up the information!?"

Su Yue said suddenly.

"Not that way."

Xu Hao said decisively, although the current network development speed is rapid, it has not reached the point where Yan and Huang Guo can't control it!

"It's been a day and a half, the Shao'an Municipal Bureau and the Provincial Bureau have been working overtime 24 hours a day to check ......"

"It is estimated that the eighteenth generation of ancestors has already checked it out, let alone an online chat record."

There's a trivia that most people don't know.

In his previous life, he always heard people say on the Internet that before he was hit and killed, he would rely on the blessing of adrenaline to empty the browser of the mobile phone, delete the chat history, and finally format the mobile phone, so that he could close his eyes peacefully.

In this regard, Xu Hao wanted to say, let's sit up on the coffin board.

Because, whether it is Penguin, WeChat, or the three major operators, the records you delete are only personal, and the company ......

The company will have complete chat log information to facilitate the state to investigate at any time, and the police also have certain rights to check it!

Therefore, before deleting the record, the police have a small probability of looking at the mobile phone, and may not see anything.

But as soon as it was deleted, the police became vigilant and directly asked the company for permission to read the records, and then it was really the pants that were ripped off and executed......

After a day and a half.

If they really found something on the Internet, the task force would have been prepared for a long time.

It's like now, two shifts, and the brow has never been loosened.

Although netizens die when they see the light, they don't have to really see the light and die!

"What's that?" Su Yue's brows locked.

In addition to the Internet, she really can't imagine anything that can make people whose household registration is hundreds of kilometers away have long-term contact with the murderer.

Xu Hao looked at a few people, but no one put forward other branch ideas, so he regretted:

"School!"

School?

Several policemen were stunned at the same time, feeling a little unfamiliar with this familiar word at this moment.

"Impossible, absolutely impossible!" Wu Chen waved his hand and said.

"One group has turned the bottoms of three victims into the sky."

"The three victims are not from the same school at all, how can they intersect!?"

That's right, if we say, the three victims went to the same school.

Then, the police car in Shao'an City estimated that it had already driven to the principal of the school.

But the police did not dispatch!

Three victims, each of whom has never appeared in the other's life!

I haven't even said a word, and I can't even talk about it at all!

"Why in the same school?"

Xu Hao suddenly spoke, and he glanced at the policemen around him.

"The three victims are not from the same school, so how did the murderer come into contact with the victims at the school?" Zhang She wondered.

Hearing this, Xu Hao smiled, the police in Shao'an City are very motivated, but they are inexperienced and think too simply.

He looked at Su Yue's confused expression and was slightly stunned.

The police in Jiangsan City are also good, and they are actively discussing problems if they have them...... Simple-minded!

"Before I explain, I want to say a word."

Xu Hao glanced at the five people around him, and the five of them immediately became energetic and looked at him intently.

"The victim is a victim because he has been in contact with the murderer to become a victim!"

"For example, Zhang San, if he has not been in contact with the murderer, but Wang Wu, then among the three corpses now, there is no one named Zhang San, and there is one more Wang Wu!"

"Then at this time, the victim of the first 'drama' is still alive and well, but Wang Wu, who was originally alive, has become a corpse."

"It's simple logical cause and effect!"

Xu Hao blurted out that the reason why the victim is a victim is because he has been in contact with the murderer and is remembered by the other party.

But he was born a victim, so he will have a certain death.

Contact is the beginning of cause and effect, not death.

"This phrase is common in any case!"

The eyes of several newly recruited police officers lit up, and they haven't made a summary yet, which is equivalent to a formula, and they can use it in the future!

Xu Hao ignored the expressions of several people.

He looked at Su Yue and said:

"Moon, how many schools have you attended?"

Su Yue thought for a while, and said suspiciously: "If you count kindergartens, there are about seven, and kindergartens and high schools have changed schools once." ”

Xu Hao nodded, "I have been to four families, but I have never been to kindergarten." ”

"What about you, Officer Zhang, how many have you been to?"

"Four of me."

"I'm four, too."

"I'm five, and I've transferred from junior high school."

"My four ....."

Several policemen spoke in turn, and Xu Hao nodded, indicating that he knew.

"Now, the school that has been the longest time, how old are the original classmates?"

"Kindergarten classmates, still seven or eight years old?"

"Elementary school classmates, still in elementary school?"

"Junior high school friends, are you still learning junior high school knowledge?"

Everyone was stunned, not knowing what Xu Hao was talking about.

"Yes, their time has not stopped, it is still changing."

Xu Hao suddenly spoke, and his next sentence immediately shocked everyone.

"But, after graduation, most of these people will not have anything to do with you......"

"Isn't it?"
