It's past one o'clock in the morning...

A vague figure sat next to the computer, ten fingers still waving wildly on the black keyboard. Each key clicked and popped up between the unusually slender fingers, making a crackling sound. It seems to be a protest, and it seems to be a wail. But Mu Xuan didn't let them go in the slightest, and had the slightest intention of stopping. Still, staring intently, energetic, and staring at the monitor without the slightest sleepiness.

Before this, Zhang Yue thought that Mu Xuan was still playing computer games, so he urged him to go to bed early at the door. Mu Xuan also followed Zhang Yue's meaning, turned off the lights and went to sleep...

Mu Xuan found that the entire system was now a fusion of viruses and original system files, and what was even more unbelievable was that the main program of the system was actually composed of only two viruses. Why did such an unbelievable thing happen, Mu Xuan didn't come up with a reason when he thought about it. Also, after checking the system, I still didn't find any useful documents, which can tell Mu Xuan what is going on.

Mu Xuan thought, since he couldn't find the reason for the mutation, he simply didn't care about why the system was in this situation. Instead, fix the error message prompted by the system. The first thing Mu Xuan fixed was the problem of network card driver, because many things had to be downloaded from the Internet. If you don't have a network card driver, you can't connect to the network to fix your computer, which is just a fantasy.

Mu Xuan repaired the network card driver in a while, which shows that repairing the network card driver is not too difficult for Mu Xuan. As soon as Mu Xuan connected to the network, the system immediately popped up one after another danger reminder windows, which is nothing more than where there are vulnerabilities in your system and where you need to upgrade.

Mu Xuan repaired them one by one, and the ones that should be patched were patched. The ones that should be upgraded have also been upgraded. After doing this, Mu Xuan looked at his watch, is it four o'clock? How can it be so fast? Suddenly, an irresistible tiredness came to his mind from all over his body, Mu Xuan thought about it, let's sleep. I'll come back tomorrow to study this weird system.

Mu Xuan pressed the power button, dragged his tired body, and fell on the bed...

The next day...

"Mu Xuan lazy pig, get up..." Outside the door, the knock on the door and Zhang Yue's coquettish sound of Mu Xuan getting up came from outside the door to Mu Xuan's ears who were sleeping...

After Mu Xuan heard the sound, he jumped up like a carp, why did he have such a big reaction? It seems that he dreamed that his sister was getting married, and when Mu Xuan went to chase after him, Zhang Yue's knock on the door sounded at this time. led to Mu Xuan's fierce reaction.

"Sister, are you annoyed? Will I be allowed to sleep again? Mu Xuan lay on the bed again at this time, closed his eyes, and said with an impatient look.

"Still sleeping? What time is it? It's twelve o'clock, hurry up and eat, my mother told me to watch you closely. "There was another voice from outside the door, the old lady. Mu Xuan didn't reply again, and after a while, Mu Xuan thought that the old sister had given up, but Mu Xuan found that he was wrong.

"If you don't get up again, then I'll rush in, I have the key, you don't want me to look at you. Wake up quickly, sleeping for a long time is not good for your health. Outside the door, there was another threatening sound of the old lady, accompanied by the crisp clashing of metals.

"Alright, I'll be up right away." Mu Xuan couldn't sleep when he saw this, so he had to respond to the Internet leisurely.

"Hurry up, give you two minutes, if you haven't come out yet, you just wait for me to come in." Zhang Yue completely ate Mu Xuan to death, he knew that Mu Xuan said so, but he wouldn't do it. This is the experience that Zhang Yue often summed up when he asked Mu Xuan to get up in the past. Therefore, Mu Xuan often looked for the key to the house, and then hid it, thinking that he could sleep with peace of mind, but Mu Xuan was wrong again, Zhang Yue, and his spare key. In this way, Mu Xuan didn't bother to mess with Zhang Yue, and told himself to get up whenever he wanted...

After Mu Xuan got up, he ate the delicious meal that the old lady had already prepared. After waking up Mu Xuan, Zhang Yue went out shopping with Bai Yunyun, girls, they like to go shopping with their good friends and the like. Especially the beauties, that kind of pride, in these two beauties have a little action in their hearts, which is simply vividly embodied. Mu Xuan thought about it, it was okay like this, so as not to bother them at home.

After Zhang Yue and Bai Yunyun left, Mu Xuan immediately closed the door, couldn't wait to turn on the computer, and began to tinker with the computer again. I have completely patched my system last night. Now, what Mu Xuan has to do is to download the relevant software that he must use, and then edit his combat weapons from the new.

"Neither of these tasks is easy!" Mu Xuan sighed and muttered. These two things are not difficult. Time, in terms of time, Mu Xuan can't afford to wait, but this is something that can't be reduced.

"It seems that the only way to do this is to take your time." Editing software is a huge project, but it is not difficult for Mu Xuan.

Time, in the process of Mu Xuan's rapid tapping on the keyboard, Mu Xuan's recklessness was also indulged in such a very rhythmic tapping sound, the extremely melancholy eyes still followed, and the redundant runes that appeared as Mu Xuan tapped the keyboard moved rapidly...

Killer's Knife···

"It's a killer..." Mu Xuan's eyes narrowed slightly at this time, and the movements in his hands also quietly stopped, looking at this code, his lips opened slightly, and muttered.

Just when Mu Xuan stopped editing the software and took a break, he found a piece of code in the main program of the system. Mu Xuan also inadvertently discovered the meaning of this code before. For a virus lover, nerves are inherently extremely sensitive to viruses.

The word killer is not known to everyone in the hacking world, but few people know it. The killer is as its name suggests. The killer, no one knows what country he is, whether he is an individual or an organization, none of this is known.

Just such a name, but it became famous overnight, that is, it used viruses to control the number of 10 million computers overnight. This virus storm has caused huge economic losses to countries around the world. But I don't know why such a fierce virus quietly disappeared from the Internet one night, and suddenly appeared and disappeared in an instant. As mysterious as the ghost of the night, what is left is only the ephemeral synonym of the killer, which proves that he has come... Those who know the code know that he has been here. But most people don't know its code, that's because the virus edited by the killer will append the word killer to the source code, and the first two words of the virus name are also named after the word killer, and almost no one can crack its source code, so as for the source of the code, there are different opinions, one of which is that the killer himself provided. Otherwise, no one knows

After this incident, hackers all over the world frantically pursued the name of the killer, whether it was Bai Dao or **···

Mu Xuan suddenly realized that it was a killer, and its virus could destroy my firewall so fiercely. "Killer..." Mu Xuan pondered again. He kept muttering.

What exactly is the purpose of the killer? Now the network is restored. Mu Xuan didn't know, and then smiled stupidly: "It seems that I won a small victory in this battle." ”

Someday, maybe it's time for the killer to change his name?
