Chapter 457

"You are not a freshman?"

Xue Xi nodded.

She also felt a little unbelievable: "no, you are a freshman, how to optimize? You haven't learned that, have you? And... "

Xue Xi said faintly: "you get out of the way."

Elder sister:.... "

She was about to say something more when a voice came from the door: "Yu Da is back!"

"Yuda is back?"

The whole computer room was filled with cheers.

She couldn't help but raise her head and looked at the door. Xue Xi also followed him. She saw Da come in. He was black and blue, and the corners of his mouth were still muddy.

After entering the door, he first threw his schoolbag beside him, then he wiped his lips and asked, "what's the matter?"

"What's wrong with you?" she said directly

"It's OK." Yu Da opened his mouth: "bitten by several mice."

Elder sister:.... "

Understanding his temper, the student sister simply did not ask: "you hurry to have a look! Our firewall has been attacked

Yu Da nodded and his sight crossed Xuejie's body. He saw Xue Xi with a frown on his eyebrows and said, "how are you here?"

Xue Xi:??

She did not finish, sister opened the mouth: "freshman mathematics department, to help, what's the matter?"

Yu Da rolled up his sleeves and went to his seat. He said, "I have a grudge against her. Drive her out."

Xue Xi:???

Elder sister:???

The elder sister couldn't help but say, "people come to help for free..."

Yu Da stood still and opened his mouth: "I am also free."

Elder sister:.... "

Someone in front looked back at him and directly called out, "Yu Da, come here quickly. I can't do it on my side! I can't hold on! "

But Yu Da stood there still, staring at Xue Xi.

After all, Yu Da's ability is very strong, but his temper is very abnormal. He is famous in the Department!

If you don't rush Xue Xi, I'm afraid Yu Da can really stand there and let the firewall be broken.

Xuejie looks at Xue Xi a little embarrassed.

Xue Xi pick eyebrows, look at Yu Da, she slowly said: "I said, my computer is very good."

The schoolsister also nodded, "yes, that's right. Just now this classmate said that she can optimize the firewall. She already has a plan! Her computer should be very good, stay and help

Yu Da sneered: "no matter how good she is, can she be better than me?"

Elder sister:.... "

Of course not.

The whole Huaxia University, who doesn't know Yu Da is a rare ghost talent in several years?!

Finally, she sighed and prayed in her voice: "Yu Da, I beg you. At this moment, if this schoolgirl can really optimize the firewall, it's also our luck. Don't be angry, OK?"

Yu Da still gave her face. He snorted in his nose. He glanced at Xue Xi and sneered: "you'd better do what you say. You can really optimize the firewall, otherwise I'll make you eat too much

With these words, Yu Da went forward and sat down in his position.

She was relieved.

Just when Yu Da came over, she stood up. She was about to sit down and continue to type code, but Xue Xi pulled the chair. Then she sat neatly in front of her computer and tapped the keyboard quickly.

She was a little worried, afraid that she could not do well, so she stood behind her and watched.

Xue Xi code typing very fast, it is very clear that they use this software very familiar, that student elder sister only looked for a while, confirmed that this schoolgirl really can optimize the scheme!

When she was about to continue to look, the teacher in front of her saw her standing and couldn't help calling her: "go and help others, don't stand there!"

When the student heard this, she didn't care about Xue Xi.

After all, the optimization of firewall can't take effect immediately. She wants to help others resist the attack from outside!

So, this schoolsister didn't find that Xue Xi, with her eyes narrowed after she left, had quietly opened another panel, and quickly knocked up the code on it.

-

Yu Da sat in front of the computer with a serious face.

Fingers on the keyboard quickly beating, let people look dazzled, he casually knocked a few times, the people next to him relaxed: "fortunately you come in time, I can't hold here immediately!"

Yu Da didn't speak. He continued to mend the loopholes and prevent others from attacking again.

With Yu Da, everyone was relieved and began to talk: "is there a person in the opposite side? So many of us can't resist him alone. It's amazing

"I don't know who it is. I think id is from abroad.""Why do these top hackers hack into our intranet? To tell you the truth, there is no secret on the campus Internet. If it is broken, Huaxia University will be very humiliating. "

A century old university, specialized in training computer talents, was actually a person broke the school network, it is a shame.

Several people are talking, suddenly a voice came: "finished, his attack is more powerful! Come on

"No, I'm broken here!"

"Shit, he was just testing. Now it's the real attack. We can't defend at all!"

"It's over, I'm broken here too!"

In the tense atmosphere, Yu Da is beating the keyboard quickly, repairing various loopholes and resisting the attack of the other party.

His face was dignified.

The attack of the other side is strong, sharp and irresistible. He has been in the computer industry for so many years. Only when x attacked the school's monitoring system did he encounter such pressure.

However, the other party is not X. every hacker has his own habits.

The other party is obviously a foreigner, but let him feel like a torrent of water, about to rush to the helpless feeling.

It seems that the other side's power on the network is as irresistible as the power of nature!

Yu Da beat the keyboard hard, trying to resist each other's impeccable strength with a weak body. Knowing that this is a mantis, he did not shrink back.

His eyes were sharp, and he closed his eyes in despair as he watched the overwhelming flood of water!

Originally thought, the network will be completely paralyzed and directly controlled by people.

But I didn't expect to open my eyes again, but there was an invisible barrier to keep the flood away!

It's not broken!

Yu Da was shocked.

Staring at the screen, he saw that the other side's attack was not only not relieved, but also more urgent and domineering. However, the barrier was firmly fixed there, giving people an infinite sense of security.

Yes.

A sense of security.

Although it seems to be only a thin layer, it is like the earth mother stretched out a gentle hand, silent and silent to block all dangers out.

Who is it?

Who's the one who helped them?!

This gentle but domineering, like a mountain like feeling It's X!

Xiake X!

As soon as Yu Da's eyes brightened, he had long been a fan of X, and quickly checked.

X is now fighting with foreign hackers and can't care about itself.

It's a good opportunity for him to take advantage of it.

He didn't want to do anything. He just wanted to find out who the idol X was.

He swallowed his saliva. Although he knew it was impolite, he hit the keyboard rudely and searched for the ID of X. The result showed that This ID address It's in the computer room!!

After seeing the seat address, Yu Da suddenly widened his eyes.

This, this is not
