in the hotel.

Professor Deli was talking to Nicholas Xiu on the phone, and their signal was completely through the channel created by Nicholas Xiu himself, and would not be heard by Huaxia Monitor.

Professor Deli opened his mouth: "I put forward a lot of temptations to Feng Shiingshen, he was very moved, and agreed to let me choose the exchange student by myself, but when I mentioned Xue Xi, Feng Shiingshen vetoed it on the spot. ”

He furrowed his brows: "If Xue Xi was just a very talented student, I don't think Feng Shishen would definitely refuse, does he also know what Xue Xi is special?" ”

Nicholas Xiu opened his mouth: "Maybe you know, maybe you ...... He didn't dare to fight Xue Xi's idea just because of Xiang. ”

Professor Deli was stunned for a moment, and then suddenly said: "Yes, it must be so!" So what now? ”

Nicholas Xiu slowly opened his mouth: "It's okay, you work hard, people can't bring it back, and learn more about her to see if it's the person I've been looking for." ”

Professor Deley replied, "Yes, Lord Earl. ”

Country.

Nicholas Xiu looked at the delicate and small computer in front of him, cut off the passage that had just been established, and after checking it, he found that there was no trace of being attacked.

It seems that Xiang didn't realize that he was on the phone.

In that case...... He decided to go to Huaxia University to see if he could get some news about Xue Xi.

Thinking of this, Nicholas Xiu put his hands on the keyboard and quickly started typing.

-

At the moment, the school computer room.

In the large room of 200 square meters, there are many servers, firewalls and other equipment, all of which are turned on and make a humming sound.

Many seniors in the third-year computer science department are busy:

"Firewall vulnerabilities are discovered, fix them quickly!"

"The new algorithm is not suitable, what should I do?"

"Haven't you come up with an optimization plan yet?"

"Nope! We brought in a few people from the math department to see if we could get any inspiration from them! ”

"What about Yuda? Why hasn't it come yet! ”

"It was said that it was a fight and was taken away by the student union, so I guess I haven't finished asking yet!"

"Those are all trivial matters, call the student union and ask Yu Da to come over quickly, isn't it clear which is more important?"

"Okay."

With the sound of buzzing talking, all the people in the whole room were busy and did their jobs, no way, the firewall in the school was suddenly attacked, fortunately it was discovered in time, otherwise, there would have been no secrets in the school for a long time.

After being discovered, the firewall has been updated and optimized, but it has never been able to stop the other party's attacks again and again.

"What to do? I can't take it here! ”

"I'm here too! Why hasn't Yu Da come back yet?! ”

When Xue Xi and Xie Yingying arrived, they saw this situation.

The whole room was a mess, and it was almost impossible to hear what they were saying, and the only thing I could understand was shouting Yuda.

Since everyone was busy, no one greeted them, only one senior sister saw two people and hurriedly asked, "From the Department of Mathematics?" ”

Xie Yingying nodded: "Yes!" ”

"How big is it? Have you finished learning linear algebra? ”

"Freshman, I haven't finished my studies yet."

The senior sister suddenly couldn't help but open her mouth: "What are you doing before you finish studying?" ”

She was very anxious and wanted to say something, but when she saw the two good-looking faces of Xie Yingying and Xue Xi, she suppressed the anxiety in her heart: "Forget it, it's all here, you guys give us a start!" Here, get a copy of this paper! ”

Xie Yingying was about to say something, but the senior sister took her mobile phone and called the student union: "The firewall on our side can't hold up, and you still won't let people go?" Do you know what's going on? If you don't let people go, our Huaxia University will lose face! Let Yuda run back! If you delay any longer, will you be responsible? ”

The president of the student union could only reluctantly speak: "Okay, okay, then let's release people first, and then go and lead people to investigate when you are done." ”

The senior sister breathed a sigh of relief.

After hanging up the phone, he looked back at Xie Yingying and saw that she was still standing in place and didn't move, so he opened his mouth directly: "What are you still standing for?" Wouldn't it be possible to print either? ”

Xie Yingying came back to her senses at this time: "Yes, yes, I'll go!" ”

She grabbed Xue Xi, took the paper, ran to the printer next to her, copied it for a few minutes, and when the copy was finished, she went to take it to the senior sister again, and the senior sister pointed to the door and said: "Go over there, wait for the seniors to come, show them, and see if there is any optimization algorithm!" ”

"Whoever has a good idea, you can bring it to me immediately!"

Xie Yingying nodded hurriedly, and dragged Xue Xi to the door.

Xue Xi: "............"

She looked at Xie Yingying and stretched out her hand: "Give me one." ”

Xie Yingying let out an "oh", handed her a piece of paper, and asked, "Sister Xi, are you okay?" ”

As soon as she finished saying this, a junior student came over, Xie Yingying hurriedly handed the paper to the other party according to the instructions of the senior sister, and conveyed the request.

Someone wants to invade Huaxia University, this is an invisible war on the Internet!

All the people of Huaxia University must come to maintain the honor of the school!

So, everyone got nervous.

The seniors who came didn't say a word, so they ran to the side to calculate, optimize the scheme, and see if there was a better algorithm.

In the room, some people continued to shout: "What about Yuda? I can't hold it anymore! ”

"I'm about to be crushed! Why hasn't Yu Da come over yet? Is he a tortoise? Crawling over? ”

"Did you reach it?"

The voices of "Yu Da" and "Yu Da" floated in the sky above the computer room, and Xue Xi listened to it with a big head.

She held her breath and looked seriously at the algorithm in her hand.

This should be an optimization plan for the firewall, but in fact, it is useless in the face of the current attack, and the optimization of the firewall can only be done after the attack and defense are over.

Now it's a battle!

She looked into the room.

All the seniors, as well as the teachers on duty in the computer room, were all working hard, staring at the screen, their hands quickly typing something on the keyboard.

There is no intrigue in the whole room, and there is only one thought at the moment, and that is to be unanimous with the outside world!

This kind of blood infected Xue Xi.

Xue Xi, who had always stayed out of things, walked up to the senior sister, and she opened her mouth: "Senior sister." ”

The senior sister turned her head, and when she saw that it was her, she asked directly, "What's wrong?" Has anyone figured out an optimization solution? ”

Xue Xi nodded: "Yes." ”

Senior sister's eyes lit up: "Who?" Hurry up and get the plan! ”

Xue Xi handed her the paper in his hand.

The senior sister glanced at it, flipped it back and forth, and said, "No? Where's the optimization? ”

As soon as these words came out, I saw Xue Xi pointing to his head: "Here." ”

The senior sister was stunned.

Xue Xi opened his mouth domineeringly: "Let me come." ”
