"That's good. Before New Year's day, there will be a computer exchange meeting across the country. The time has not been determined yet. It is mainly aimed at the students of this experimental class. We only have you and Qidong here. So I hope you can make a success of this course."

Zhao ordinary said this, the expression on his face is very proud.

The child in Qidong, needless to say, has a good family background. She has been exposed to computers early, and has been programming for a long time. However, Xu Yun's family background is not so good. However, when she chooses a computer, Zhao Pingfan has observed it quietly. Xu Yun's computer operation is very skilled, and the starting point is much higher than those who are half baked.

When the time is fixed for the exchange meeting, he will take Xu Yun and Qi Dong together. I believe they will not lose the face of Star City, and maybe they can shine.

Out of Zhao ordinary's office, Xu Yun's heart beat a little faster.

National computer exchange meeting? That's only for the top elites of IT industry.

In her last life, she couldn't dream of something. In this life, she had the chance to touch it. To say that she was not excited, it was a fake.

For a moment, she was in a state of mind, and could not be calmed down for a long time. She even walked to the door of the laboratory unconsciously, but did not notice.

Qi Dong had long seen Xu Yun, who was absent-minded. He snorted in his nose and said, "Mr. Zhao told you that before New Year's day, there will be a national exchange meeting. I hope you don't drag me down."

It's this sentence again. After Xu Yun's recollection, she's a little hairy.

She knew that she was born again, but her pride still remained unchanged. To put it bluntly, she was not afraid of academic failure. What she was most afraid of was her collapse and betrayal.

"Qidong, did you invade my computer?" Clean up a good mood, Xu Yun calm face.

Qi Dong snorted and muttered: "voice robot, foreign countries have mastered mature technology, you can't do that."

Well, she's sure he's already hacked, and with his hacking technology, I'm afraid her computer has become his chicken.

Damn it.

Fortunately, she did not record anything private on the computer assigned by the school. Otherwise, how embarrassing?

"So your hacking skills are amazing."

Referring to his major, Qi Dong is very proud, hum a way: "I made a firewall, you come to help me operate the invasion."

With that, Qi Dong doesn't wait for Xu Yun to nod. He picks up a hard disk and connects it to Xu Yun's computer.

Next, the computer that Xu Yun uses, turn on automatically, appear innumerable source code overlapped shadow

Xu Yun's face changed, he ya, actually took her computer to plant a virus, which felt like raising snakes in the hall without the owner's consent!

"Qi Dong, do I agree with you to use my computer?"

Qi Dong turned her head and gave her a look: "you don't like it. Clear it yourself."

Nima, this is the red fruit provocation!

Don't force her. She's really worried. It's not that you can't study hacker technology.

"Well, you try to operate, I defend, you attack." After Qi Dong finished, he looked back at Xu Yun, whose face turned green. He said, "Mr. Zhao wants to see the research results. Personally, I think the firewall is the best technological achievement. We are the same group. Then let them see what is invasion and what is defense. This is the most perfect."

After stopping, Qi Dong said brightly: "and this domestic exchange meeting." After that, Qi Dong said sarcastically: "your voice robot is not good at the exchange meeting. Xu Yun, since you have entered the experimental class, don't give us shame. If you want to do it, you should do the best."

Xu Yunshen took a breath, but her face didn't get better, but she had to admit that Qi Dong was right. The voice robot she made was not very good and could not handle it. In the IT industry, she did see the real chapter with the program.

In a thousand turns, Xu Yun swallows the gas back, and seriously walks to the back of Qidong, and begins to observe the virus he wrote, as well as the intrusion program.

Qi Dong saw her calm down, not as angry as other girls, eyes across a bit of surprise, but soon pleased to speak, and then carefully teach Xu Yun how to operate.

Hackers are also called hackers, and hackers are divided into black hat hackers, gray hat hackers and white hat hackers. Black hats are mostly intruders, that is, attackers, while white hats are mostly defensive. For example, the firewall written by Qi Dong belongs to the white hat defenders of the security system, as for grey hats! It means that they can walk on the edge of the law. They can be just or evil.

After Xu Yun understood the attack technology, she was shocked to find that Qidong's firewall was perfectly written. Under the impact of countless times, it stood still and could not even find a flaw.

Of course, it is also possible that the virus written by Qi Dong is aimed at this firewall itself. If you want to be very sure and determine the capability of this firewall, the best way is to find other experts to invade.During the invasion and attack, Xu Yun suddenly found that she actually liked this technology. Especially, in Qi Dong's virus, she felt that she could add some more elements, and then let the virus mutate into two parts, two parts, four parts and eight parts.

After discovering this, Xu yunminrui felt that her blood was boiling, just like playing hormone, which made her extremely excited.

"Qi Dong, give me some time. When I'm ready, we'll try again." Xu Yun's eyes brightened.

Break the firewall, this is like playing a game, can't pass the customs let Xu Yun some grasp heart and lung, but also arouse her strong interest.

Qi Dong in Xu Yun's eyes to see the passion of not admit defeat, Zheng Chong after a few seconds, proud way: "good, I wait for you."

Back in the dormitory, Xu Yun is full of virus code and the three defense lines of Qidong firewall. She doesn't even touch her mobile phone. Naturally, she doesn't see the six missed calls above.

In the next few days, Xu Yun rescheduled her schedule, opened cultural courses, and experimented with sweets. After that, she was in the laboratory and mutated Qidong's virus.

Because Xu Yun deliberately cut off the network research, so Qidong simply did not know that Xu Yun not only evolved his virus, but also compressed and split, and constantly mutated. Finally, he joined the explosion element in an all-out way.

This blasting element is like the Last Assassin's mace of a strong attacker. To put it bluntly, savage invasion can not only destroy the program software, but also quickly attack the other party. A yes can make the opponent become his own springboard chicken, and a no can directly destroy the heaven and earth. #####
