"One..."

The girl with student number (1) walked up to the podium, sat in front of the computer that had been restarted, and began to crack the campus intranet.

The computer at the front has remote sharing turned on, and all the computers below can see the girl's operation. The classmates held their breath one by one and watched intently at how the girl operated.

Then, I saw that the girl logged in to her Baidu account, logged in to Baidu cloud disk, downloaded a toolkit from it, unzipped out a set of software in English and foreign languages, and began to scan the computer for vulnerabilities.

To be honest, when I first saw her actually land on the cloud disk, Chu Feiyue was choked by thunder. However, the software still looks good, and in less than a minute, eight medium-risk vulnerabilities and two high-risk vulnerabilities were swept out of the computer, and then automatic fixes began.

At the same time, the girl opened another installer and began to install the firewall and some small software she was used to using on this computer.

Everyone's habits are different, so Chu Feiyue doesn't know any of the software used by this girl. But it's in English and Russian, and it does look like it's amazing...

Chu Feiyue swept to the side, and many people showed expressions of admiration, it seemed that this girl's skills should be considered top-notch in the class.

Soon, the patching of the vulnerability was completed. The girl nodded at Liu Siqian, and Liu Siqian pulled out a chair nearby and sat on it.

In the next second, the prompt sound of tapping the virtual keyboard sounded under Liu Siqian's hands like a rainstorm hitting a lotus leaf. Several students who were close to them saw that seven or eight black DOS windows had opened on Liu Siqian's computer like lightning, and she was writing different content on them at almost the same speed!

The girl sitting in the front nervously clicked on one program after another to put as much protection on her computer as possible. It can be seen that Liu Siqian's inhuman speed of typing on the keyboard below has given her a lot of pressure.

Immediately afterwards, Liu Siqian pressed the enter key suddenly, and several windows in front of her began to run automatically one after another. A large row of rows of numbers jù began to refresh constantly.

Chu Feiyue secretly shook her head for the girl in front of her, thanks to her for putting so much effort into perfecting the broken computer that was riddled with holes, but she forgot the most important one. Liu Siqian doesn't even need to operate in practice, and now she has compiled a few small software to snatch her management rights...

Sure enough, the classmates around "Coming, coming!" In the exclamation, the computer screen of the (No. 1) girl suddenly froze, and then a large number of communication protocol request pop-ups suddenly swiped out, directly holding the girl's already small CPU to 100%. Computers that have been flooded with requests for communication protocols have no ability to discern the few seemingly inconspicuous but deadly instructions that are mixed in.

The girl in front of her was already dumbfounded, her computer was now on the verge of collapse, and the command input of the mouse and keyboard and so on all failed, and she could only stare at the pop-up windows that kept appearing on her computer to cover the computer desktop.

Immediately after, all pop-up windows, including the entire desktop, disappeared, leaving only a piece of pure white and two lines of small black text in 10 on the screen.

[The foundation is good, but you forgot that we are now in an area network, and your protective measures are almost all wasted. 】

【Subjects you want to study: ......】There is a long row of more than a dozen names listed behind, and they all look cautious.

(1) Girl No. 1 cried with a sad face, looking at Liu Siqian with a relaxed face below with grievances and fear.

"Teacher... Let me do it all over again, okay..."

"Yes," Liu Siqian tilted her head, and the ponytail behind her was curled, "Wait until a year later, when I test it again." In the final analysis, the problem of forgetting about the LAN is that your foundation is not strong, and it will not hurt you to learn more about the basics. ”

Anyone who is familiar with Liu Siqian can see her current feelings from her ponytail, for example, now, although she didn't say anything, Chu Feiyue knew very well that this guy was actually proud.

I beat up a child once, and I was refreshed...

And there is a large wave of children waiting for her to beat her...

It's cooler...

Girl No. 1 took a picture of the subject she was going to study with her mobile phone, and restarted the computer that had crashed in frustration. Then, girl (2) stepped onto the podium in horror and began her own test.

This kind of feeling is really no different from the execution ground for Chu Feiyue.

The classmates have already seen that the level of the teacher is completely the same as that of their group of wild people, and it is not comparable at all. But in order to allow them to take fewer classes and have more free time in the coming year, they can only go up and go all out.

Then I watched as the defense system that I had spent a lot of effort building was easily torn apart by Liu Siqian in less than a minute, and was brutally ravaged from the spiritual level...

The time it took for each student to patch vulnerabilities and install defenses ranged from one minute to four minutes, but none of them were able to sustain the total time beyond five minutes.

About two hours later, it was finally the turn of (3) and (3), and it was time for Chu Feiyue to take the stage.

Chu Feiyue sniffed, feeling that her nose seemed to be a little out of breath. Wearing so many clothes on such a hot day, could it be that you are caught by the heat?

Under the gaze of the whole class, Chu Feiyue slowly walked onto the podium.

I went around to the back of the computer that had been restarted and crouched down.

Unplug the network cable.

"Alright, here you go." He rubbed his nose with one hand, held the dark blue net cable with the other, and said to Liu Siqian angrily.

Liu Siqian &&& Class: ⊙_⊙b Khan......

Liu Siqian was angry and shouted to the bad Chu Feiyue: "Chu Feiyue! You've got it for me! ”

"Suck-suck—actually, the first time, I wanted to do it, but you didn't give me a chance." Chu Feiyue was helpless, plugged the network cable back in, sat on the chair that looked like a high platform in the execution ground, and turned her head to look at Liu Siqian, who was still puffing up, "Isn't it, the classes are all arranged by you?" ”

"That's right, if I see anyone who is unhappy, I will ask him to copy all Tang poems three hundred times."

Liu Siqian narrowed her eyes and looked at the repetition of Eyue gloomily, which clearly meant "If you don't give me a good fix, my mother wants you to have hand cramps." If you put aside her personal feelings, Liu Siqian is a teacher and Chu Feiyue is a student, so there is really no reason to push back Chu Feiyue with such a willful request.

After all, the number one leader of this school is her grandfather, and Chu Feiyue is such a common person, and he can't help it if Liu Siqian really asks him to copy all Tang poems three hundred times.

Teacher...

While secretly regretting why she didn't harden her mind just now and walked out of that threshold, Chu Feiyue restarted the computer again, entered the safe mode, and called up the control panel and began to modify various parameters. Chu Feiyue doesn't think that this computer really has so many vulnerabilities, and it doesn't always be the same? Are you kidding...

The only explanation is that in fact, there are all the patches in this computer itself, but there is a * program that has been making trouble in the back, and every time it restarts, it deliberately restores some vulnerabilities. As long as you find that program and delete it, Chu Feiyue doesn't need to patch it anymore.

Glancing from top to bottom, Chu Feiyue found two hidden program items with similar names, and found the root text jiàn, which was obviously not where the program should be. Chu Feiyue used the extractor to extract the programming code of that program and glanced at it cursoryly.

The approximate function is to randomly pick a few items from a list at each reboot, delete their patches, and let the vulnerability leak out again. A simple, but ingenious program...

There is no shared desktop in safe mode, so the people below don't know what Chu Feiyue is doing on stage, but Liu Siqian probably guessed Chu Feiyue's thoughts, and the corners of her mouth turned up slightly.

Chu Feiyue didn't delete this disgusting little program, but added a string of code to the back, so that it would sleep after this startup, and run as usual after the next restart. After all, he still has someone else to take the exam behind him, what if he deletes the person behind this program?

Exiting the safe mode, Chu Feiyue manually detected a few vulnerabilities that she knew, and found that they had been blocked, so she no longer had any patching tools, and said directly to Liu Siqian: "I'm okay, let's start." ”

"That's what you said."

Liu Siqian crossed her fingers, twisted her wrists up and down, and moved her fingers before putting her fingers on the keyboard.

The next moment, the keyboard key beep sounded in a storm. The classmates in the class were surprised to find that while Liu Siqian was writing instructions, Chu Feiyue was also doing the same thing. And his hand speed doesn't seem to be much slower than that of the head teacher!

They didn't know what Liu Siqian's desktop was showing, but they could see Chu Feiyue's desktop. They could see that on Chu Feiyue's desktop, a whole line of code was appearing at an extraordinary speed, and then it was sent out, so fast that they couldn't even read anything clearly when it was written on it, and Chu Feiyue changed lines again.

Then, one black window after another popped up on his desktop, but most of them were forcibly terminated before they could run for a few seconds, and few were able to stay on his desktop for more than five seconds. At the same time, Chu Feiyue's number of streams was also constantly impacting Liu Siqian's computer, placing dark thunder one after another in her computer, but they were all thrown back by Liu Siqian before they were started.

The invisible battle between the two people is getting more and more intense...

Gradually, Chu Feiyue showed a declining trend, and the black frame on his desktop stayed longer and longer, and there were more and more of them. Seeing that, Liu Siqian was about to win.

All the viewers' screens suddenly "snapped" and then changed back to their own desktops.

"Hey, what's going on?" "It's climaxing, what..." "Unfortunately, !!!"

Liu Siqian stood up "Teng", staring at Chu Feiyue angrily. Under Liu Siqian's angry gaze, Chu Feiyue scratched the tip of her nose and smiled evilly.

"That,Maybe the network cable wasn't plugged in just now.,It's dropped.,Hehe..."
