"What are you doing this for?" Lin Ming was puzzled: "Why did Kaizi go to the scene of the crime?" Who exactly is the murderer? ”

Zhang Shaoan said: "The origin of this matter is to talk about a detective forum. ”

"Detective forum?"

"Nowadays, there are all kinds of forums on the Internet, which are popping up like mushrooms after a rain, and when I search the Internet, they are everywhere, and I often go to these forums myself, but I don't go to detective forums, I usually go to forums like math and physics to find people to talk about academic topics. Kaizi found some detective forums on the Internet, because there will be many works by world-famous detective fiction writers, and from time to time, there will be cases created by netizens and some unsolved mysteries in real life on them for people to interpret. Kaizi met an opponent in a very secretive and top-level high-IQ forum, let's call this person Suspect Y. ”

"Suspect Y?"

"Yes, this guy is interesting. Every time a case is released, he will snatch it with Kaizi to see who will solve the case first. Because this forum is a point system, whoever solves the case first will have some points. At present, Kaizi is in second place, and suspect Y is in first place. ”

Zhang Shaoan added: "The reason why Kaizi is second is not that this suspect Y is better than Kaizi, but that Kaizi doesn't have so much time to surf the Internet. Every time Kaizi is there, try to compete with him, and Kaizi will win at least 8 percent or more. But it was precisely because Kaizi had little time in the forum that he was surpassed by this suspect Y with the total points. ”

"And then?"

"Then when Kaizi was there, suspect Y's points would never grow, so suspect Y was very unconvinced that Kaizi won every competition, so he sent an email privately, provoking Kaizi, saying that he wanted to have a competition with him."

"Competition? What is the competition? ”

"Suspect Y said that at 3 a.m. on July 23, Hu Jie would die."

"Wait."

Lin Ming immediately realized the key point and interrupted him: "This suspect Y actually knows Hu Jie? Could it be that an acquaintance who knows Zhou Yunkai committed the crime, no, no one knows about Hu Jie except me, Uncle Zhou, Yuan Hao and a few policemen. Even if it's you, I guess I only found out about it recently. ”

"Yes, I didn't know about this until a few days ago, when Kaizi asked me to set up this alibi."

"Then how could he possibly know Kaiko's secret?"

Lin Ming frowned.

He saw Zhang Shaoan's expression smiling, as if he had already understood this question. Suddenly, a flash flashed in his mind, and he was surprised: "Kaizi must have put this matter on the computer and made a detailed and careful plan, so it was stolen." Since suspect Y has been able to soak in the forum for a long time, it means that he is in front of the computer every day. Hacker! ”

Zhang Shaoan nodded approvingly and said, "Yes, Kaizi and I think so too." Neither of us knows much about computer knowledge, which has only emerged in recent years. So at the beginning, Kaizi didn't protect these materials in detail, and put them in the computer, and the only thing that could steal them was hackers. ”

Hackers, a new profession that has quietly emerged with the Internet era in recent years. It can follow your network, invade your computer, empty all the data in your computer, and can also issue various commands to your computer for remote control.

At the beginning of this year, Shanda, which became popular on the Internet because of its legend, suffered an unprecedented hacker theft case. Shanda suffered heavy losses and was almost on the verge of bankruptcy. It makes hackers legendary among the people, representing the mysterious and unknown.

In Lin Ming's view, hackers are just ghosts, thieves, and thieves in the online world, who are everywhere, drill into the cracks, and use Trojans and viruses to maliciously crack commercial software and maliciously invade other people's websites to steal anything they want to know. It is a cancer in the network and a public enemy of the Internet industry.

Lin Ming is currently going to be Mingran Technology, and the biggest enemy is actually not competitors, but network hackers.

Once his Tian Lai Music Network was hacked, it would actually hit him very hard. Therefore, Lin Ming was in a state of hostility towards hackers, especially after hearing that the friend who framed him was also a hacker, Lin Ming hated hackers even more. I've already started to think about whether I need to invite some celebrities to help participate in this incident.

Different from the attitude towards hackers, Lin Ming still respects and appreciates the red customers who are engaged in the field of Internet protection and maintain the security of network invasion. Long before he became Mingran Technology, he had the idea of hiring some network security experts, also known as technicians commonly known as red customers, to help maintain the website.

Now that something like this has happened, Lin Ming is thinking that maybe he should contact some celebrities and let them see if they can follow Zhou Yunkai's hacked computer to find the intruder, so as to solve this murder case.

Otherwise, there is such a murderous maniac who knows his details well and will burst out and kill at any time lurking around, whether it is for Zhou Yunkai or his family, it is a danger.

The matter had been fully clarified, and Lin Ming and Zhang Shaoan fell into silence for a while. After a few minutes, Zhang Shaoan's mobile phone vibrate, he clicked on the text message, and after reading it, he said: "Kaizi came out, I asked him to come here and make peace with us." ”

Lin Ming nodded, he had too many questions to ask Zhou Yunkai.

After a while, Zhou Yunkai's figure appeared at the door. He was summoned in, not even detained. After using the alibi to clear the suspicion, with his father's relationship, he was released smoothly with almost no obstacles, and Jiao Erlang appeared in the café locally.

"Kaizi, this way." Lin Ming beckoned him to come over.

Zhou Yunkai's mood seemed to be good, and he was not as angry as he imagined, which surprised Lin Ming. His hands were in his pockets, and his brisk steps seemed leisurely.

"Lin Ming, why are you here?"

Zhou Yunkai pulled out a stool and sat down, beckoned to the waiter, and ordered a cup of coffee.

Lin Ming didn't confess Yuan Hao, so he avoided the seriousness and said lightly: "The captain of the criminal police team who handled your case is my uncle, do you think I can come and take a look?" ”

"Yuan Hao told you, you don't need to hide it from me, you have already guessed it." Zhou Yunkai took out a pack of cigarettes, smoking is prohibited here, but this corner is far away from the hall, and there is a table of people nearby, which does not affect others, so the waiter turns a blind eye.

Lin Ming was surprised: "When did you become addicted to smoking?" ”

"It's not a big addiction, and I like to smoke one when I think about problems." Zhou Yunkai handed one to Lin Ming, and asked Zhang Shao'an: "Master An, come with one?" ”

"No." Zhang Shaoan shook his head.

Lin Ming lit a cigarette, took a puff, and spit it out lightly after passing through his lungs. In his previous life, he was a big smoker, at least one and a half packs a day, but when he became addicted to smoking, he was in college, he was 20 years old, his body was very mature, and the damage was much less. He was only 15 years old in this life, and he deliberately controlled his addiction to smoking, otherwise he would have serious lung problems in the future.

The two swallowed the clouds for a while, and Lin Ming asked, "Kaizi, what's the situation?" Who is that suspect Y? Do you have any ideas now? ”

"You got it?" Zhou Yunkai was a little surprised.

"An Ye told me."

Zhou Yunkai nodded: "Since you know, let's listen to it together and help refer to it." ”

As he spoke, Zhou Yunkai recounted the incident.

At the beginning, he received a private message from suspect Y, but Zhou Yunkai didn't really care. Because in his opinion, it is not important to win or lose, but the fun of solving those puzzles on the Internet.

But what Zhou Yunkai didn't expect was that suspect Y seemed to know him very well, and actually said his name and Hu Jie's affairs.

This made him immediately realize that his computer had been hacked, and it also made him realize that the person seemed to be doing something serious.

It wasn't until the last private message came that Zhou Yunkai was sure that this person might really be able to bring some fun to himself in a boring life.

There is only one content in that private message, at 3 a.m. on July 23, suspect Y will go to kill Hu Jie, and then let Zhou Yunkai solve the case and arrest him.

The time, place, and people were all told to Zhou Yunkai. This seems to be a matter that only needs Zhou Yunkai to use a little relationship and let a few well-known policemen come over, and it can be easily handled.

But Zhou Yunkai is not stupid, and before he is sure that the other party really has the courage to kill someone, he will not immediately call the police to go over and beat Hu Jie to the snake, so that the drug trafficking case will fall short.

So he found Zhang Shaoan and acted in a good show of alibi.

As it turned out, he was also thankful that he was thoughtful.

Because he didn't expect that the other party actually got his fingerprints and put them on the murder weapon used in the crime to blame himself.

If it weren't for Zhou Yunkai's early precautions, he might have fallen into the opponent's trap in the first round.

"This is a very smart criminal." Zhou Yunkai smacked his lips and said excitedly: "I always wonder if I will meet such an opponent to fight in the ring with me one day, but I didn't expect happiness to come so suddenly." ”

Lin Ming said: "It's a little hard to figure out, how did he get your fingerprints. ”

Zhang Shaoan said: "Kaizi and I are actually thinking about this problem, it is not difficult to take fingerprints, and it is not difficult to forge and copy fingerprints. A bottle of cyanoacrylate binder, toner, tape, gelatin or silicone, all of which cost no more than 5 yuan, can collect a fingerprint, copy it, make a fingerprint film, and press it on the murder weapon casually. But to get fingerprints, it's a very difficult thing to do. We are all students, and our daily life is basically two points and one line, home - school. The most fingerprints exist, naturally in these two places. It's not realistic to look for fingerprints at home, so you can only go to school, so I guess that the other party must have gotten fingerprints at school. ”

Lin Ming said: "In other words, suspect Y is a local? ”

"Nope."

Zhou Yunkai shook his head: "It's hard for me to imagine that such a highly intelligent person would personally go out to kill people." To be honest, I don't believe he would do that. ”

"Anything is possible?"

"Not that way." Zhang Shaoan said: "The deceased's family lived on the third floor, although there were water pipes and anti-theft nets as supports, but from the 2nd floor to the 3rd floor, you must step on the anti-theft net below in the middle, and then climb up to the 3rd floor by pulling up with your arms, so that it is difficult for a person who has stayed in front of the computer for a long time to climb to the third floor so vigorously." ”

"Makes sense."

Zhang Shao'an's analysis is very accurate, which makes people feel like this.
