After a full meal that night, Chen Xu and Gao Xiaojie went out almost horizontally.

The table was full of dishes, half of which were seafood and shellfish, and all of them were finally stuffed into the stomach by the two of them, and the greasy smell was ...... Chen Xu almost went to the toilet and vomited a few times. After getting into the taxi, Chen Xu swore that he would never eat seafood in the next half a year, and Gao Xiaojie hummed vigorously with his bulging belly, and said very depressedly that this is over, this meal will weigh at least three catties after eating, and he will lose weight......

But looking at her like this, she basically doesn't remember much about what happened in the afternoon, which made several people breathe a sigh of relief. I heard that the other three girls who were not seriously injured in the attack, one of them had already taken a break from school and went home, and the other two were not having a good time, and they were worried all day long, and they had to find classmates to follow them wherever they went.

After all, this is a psychological shadow, and it's good that she doesn't have this shadow.

In the afternoon of the next day, Chen Xu went to the lying police station again. The first thing I said when I saw the policeman's brother was: "I drew a picture after I went back yesterday, about the man who cut his throat, I hope to give you some help." ”

Chen Xu took out the USB flash drive and plugged it into the computer of the police station, and then double-clicked on one of the pictures called "Cutthroat Man .jpg", seeing this picture, the policeman's brother was a little dizzy, Chen Xu scratched his head embarrassedly: "I haven't learned to draw, especially on the computer, it's good to be able to draw like this." ”

The policeman's brother rolled his eyes and said "Who are you, you are a half-orc!"

On the screen is a drawing made with the most ordinary drawing software, and you can vaguely see that this is a person...... A red jacket, a dark blue woolen hat, a large black-rimmed glasses and a mask. To be honest, seeing this picture is no different from not seeing it, but Chen Xu also annotated on the side: "Height 180-183, male surname, about 25 years old, physically stronger than ordinary people." ”

Several of the policemen felt that they couldn't laugh or cry, thinking that this student was too funny, and the thing he drew was not as expressive as the expert drew according to his confession after he dictated it yesterday. And when he saw the painting painted by the expert, Chen Xu was very embarrassed and said: "Oh, it's really like, it's much more like me!" I said earlier that you have such talents, and I still came out to offer ugly things! Hey, I'm sorry. ”

Chen Xu's attitude made the police a little embarrassed, after all, they are students, and it is worth advocating to take the initiative to help, so a group of people smiled and replied that it was okay, and the attitude was very encouraging! Yesterday, thanks to the stone you sent, it was found that the blood on the stone was type A, which made a breakthrough in our work.

Chen Xu pulled out the USB flash drive and said that this is what I should do, so since this is the case, I will leave and not bother.

Then he ran away in a puff of smoke, but a group of stupid policemen didn't notice that after Chen Xu walked out of the door, a smile of conspiracy appeared on the corner of his mouth.

The picture in this chapter is carefully designed by Chen Xu, of course, the so-called meticulous refers not to the throat-cutting man who looks like a half-orc in the picture, but to another aspect.

During this period, Chen Xu also officially started the study of "Chinese language", not only was he able to write scripts to generate and produce corresponding software, but also had a certain understanding of computer software and hardware while learning.

This time, Chen Xu took advantage of an undiscovered vulnerability in the XP system, which was a vulnerability in the picture fax viewer that came with XP. This vulnerability can be exploited to unknowingly import Trojans into the system, embed key desktop process explorer.exe files, and secretly open ports to make the computer on which the Trojan is installed a broiler.

Chen Xu pretended to open the picture, in fact, the main purpose was to open the picture fax viewer, and then activate the Trojan horse entry system. And this Trojan also has the function of automatically recording keyboard actions, which can allow Chen Xu to steal the password together.

The name of this Trojan horse was named by Chen Xu as "Killing the Man Who Cuts His Throat", which is the first Trojan horse he made by his own reading power in his life. Of course, the vulnerability used was not discovered by Chen Xu himself, he only discovered and exploited this vulnerability after getting Xiaomin's tutorial, and it was based on the template of the earliest "gray pigeon Trojan horse variant" to develop such a Trojan virus.

And the method of delivering this Trojan horse is also ridiculous - how can any hacker run to install a Trojan horse on someone's computer? But this can't be done, because in the absence of a backdoor, with Chen Xu's current technology, even the system protected by the Rising Firewall cannot be invaded.

But in any case, this is Chen Xu's first work, and it should be said that it has epoch-making and milestone-like significance. And Chen Xu set this virus to be automatically cleared after a day for the sake of insurance, so that as soon as the virus disappears, no one will know about it anymore, God doesn't know it, how good!

In fact, if it weren't for Chen Xu being forced to be helpless, how could he have adopted this method? But now it makes no sense to say this, after Chen Xu came out of the police station, he got into a small hotel next to him, opened an hourly room, and opened his Trojan terminal after connecting to the network with Xiaomin and began to invade.

Because it is now a unified replacement of the second-generation ID card, there is no worry that the police comrades will not open the inquiry system. However, when it comes to the second-generation ID card, Chen Xu thinks of Xiaomin's census system. Because he has changed the second-generation ID card, he knows that the second-generation ID card has an IC chip, which can record personal information, but the record is not rich enough, and the blood type, fingerprints and the like may not be recorded. In fact, this technology is already achievable, but I am afraid that it has not been done because of the high cost. As for the future census system, it is probably based on this basis.

Sure enough, Chen Xu's Trojan terminal mailbox received a stolen email in the mailbox.

So Chen Xu swaggered into the other party's computer, and at this time found that the ID card query system was already open, so he entered the ID number of the throat-cutting man Huo Hu, and the corresponding information was immediately found in it.

"Huo Hu, male, born on July 22, 1980. Ancestral hometown: XX City, XX Province......

In 1998, he was admitted to Southwest Jiaotong University (fictional......

In 2002, he was admitted to the Department of Mathematics of Southwest Jiaotong University

After graduating in 2005, according to the employment report of graduates of Southwest Jiaotong University, he went to XX City University of Technology to teach......"

"Sure enough, it's in our city!" Chen Xu slammed the table excitedly, and then saw that there was no information available, so he quietly retreated, and erased the search results just now - because although Xiao Min helped him deal with the aftermath every time, Chen Xu said in the first lesson of learning hacker common sense that the most important thing for a hacker is to protect himself. So this habit must be adhered to.

After finding out Huohu's information, Chen Xu immediately logged on to the official BBS of the University of Technology.

The University of Technology is also a very well-known university in the city, which is not much different from the University of the United States. However, the University is a comprehensive university, and the University of Technology is biased towards science. The two schools are not close to each other, they are five or six bus stops away, so there is not much connection between the two schools.

Chen Xu registered an account after logging in to Shanggong**bs, and the first thing he clicked on was the search of the forum, and the keyword was "Huohu".

The BBS popularity of the University of Technology is also quite high, and there are many posts. As soon as Chen Xu searched, he didn't know if he was lucky or Huo Hu was unlucky, but he really let him search for a post about "Huo Hu".

There were several posts, and Chen Xu opened them one by one and found that they were all sent by some students. But what surprised Chen Xu was that after clicking on the post, the description of this Huo Hu in it was all praise!

A post said that Mr. Hohu's lectures were very lively and the people were very funny and humorous. One post said that Hohu's man was very good, and his classmates liked him. There is also a post saying that everyone goes on a spring outing together, how happy is the fun......

Chen Xu was a little stupid at first glance, could it be that he made a mistake? Is this just a duplicate name, or is it simply that the blood pressure on that stone is not the throat cut man, but the hapless Hohu? And then I accidentally found the wrong stone, or was the stone unfortunately stuck to Hohu's blood a long time ago, but it was scanned by myself?

The more Chen Xu looked at the post, the colder his heart became, thinking that this is over, and all the clues are broken!

And in the post there are some photos, one of which is named "Me and Teacher Hohu". On the photo, the two people can tell which one is the teacher and which is the student at a glance. Although the above Hohu is also more than 1.8 meters tall, he looks obviously thinner than the man who cuts his throat...... Is it really not him?!

"Nope." Chen Xu thought for a while and said to himself: "You can't draw conclusions so early, I still have to investigate...... Let's investigate whether the back of his head has been smashed. ”

And at this time, in a community outside the University of Technology, Huo Hu, who was considered by all the students of the University of Technology to be Mr. Yes, a model teacher and his brother, was struggling in bed very frantically.

His eyes were blood-red, and his face was white without a trace of blood. His hair was messy like straw, and at the back of his head, there was a piece of white gauze that stood out!

On the gauze, blood oozed from the red!

"Woo woo woo" Huo Hu let out a mad dog-like bark, he bit the pillow desperately or the sound would come out, and it was hard to vent later. Huo Hu roared in a low voice: "No, we can't go on like this!" What about the medicine, what about the medicine?! ”

Then he glanced at the computer screen again, then pulled his hair frantically, panting like a wounded beast, and roared, "I'm going to kill her, I'm going to kill her!" They are so similar, why do they look so alike?! ”

On the computer screen, there are pictures of a girl flowing and changing, sometimes bright and lovely, sometimes smiling, sometimes innocent and cute, sometimes vigorous - it is Gao Xiaojie!

These photos were taken during her interview!

And on the desktop, there is also an open, password-added word document, which reads:

"December 24, Christmas Eve.

I missed. I searched for a long time, and finally saw her working in the cake shop on the pedestrian street, this is really the best opportunity God has given me! I've been watching her, but I didn't expect her to be in the middle of the city, and I didn't have a chance to do it. I finally watched her walk to the middle of the alley, but I didn't expect her to wear something around her neck......"

"I'm hurt, but I'm not going to give up! Because they're so similar! And in the name, there is a section word! ”

Huo Hu fell on the mobile phone screen on the side, as a picture is a photo of him and a girl, it is a very pure and petite Jiangnan girl, this girl is smiling brightly, and there is a three-point look between her eyebrows and Gao Xiaojie. It's just godlike, because that cuteness, that kind of flying, it's all exactly the same.

And if the police saw this photo at this time, they would be surprised, because this girl died tragically on November 10, the first victim at the hands of the throat-cutting man, and the only girl to die.

Her name is Bai Jie!
