The senior sister was stunned, and subconsciously opened her mouth: "Aren't you a freshman?" ”

Xue Xi nodded.

The senior sister still felt a little incredulous: "No, you are a freshman, how did you optimize it?" You haven't even learned that, have you? And ......"

Xue Xi said lightly: "You get out of the way." ”

Senpai: "............"

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

"Yuda is back?"

The entire computer room burst into cheers.

The senior sister couldn't help but raise her head and looked at the door, Xue Xi also looked over, and saw Yu Da walking in, his nose was blue and his face was swollen, and the corners of his mouth were still bruised.

As soon as I entered the door, I threw my schoolbag aside, and then I wiped my lips and asked, "What's wrong?" ”

The senior sister opened her mouth directly: "What's wrong with you?" ”

"It's fine." Yu Da opened his mouth: "I was bitten by a few mice." ”

Senpai: "............"

Knowing his temper, the senior sister simply didn't ask: "Hurry up and take a look!" Our firewall has been attacked! ”

Yu Da nodded, and when his eyes swept over his senior sister, he just saw Xue Xi at a glance, his eyebrows frowned, and he frowned coldly: "Why are you here?" ”

Xue Xi: ??

Before she finished speaking, the senior sister opened her mouth: "Freshman math department, here to help, what's wrong?" ”

Yu Da rolled up his sleeves and walked to his position, and said: "I have a grudge against her, drive her out." ”

Xue Xi: ???

Senpai: ???

The senior sister couldn't help but open her mouth: "People are here to help for free......"

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

Senpai: "............"

Someone in front of him looked back at him and shouted directly: "Yu Da, come here, I can't do it here!" I can't hold it anymore! ”

Yu Da stood there still, staring at Xue Xi.

Senior sister understands his strange temper, after all, Yu Da is super capable, but his temper is very perverse, which is famous in the department!

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

Senior Sister looked at Xue Xi with a little embarrassment.

Xue Xi raised her eyebrows and looked at Yu Da, she said slowly: "I said, I have a good computer." ”

The senior sister also nodded, "Yes, yes, this classmate just said that she can optimize the firewall, and she already has a plan!" She should have a good computer, so stay and help! ”

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

Senpai: "............"

Of course not.

In the entire Huaxia University, who doesn't know that Yu Da is a rare ghost talent in a few years?!

The senior sister finally sighed, with a plea in her voice: "Yu Da, I beg you, at this moment, if this senior sister can really optimize the firewall, it is also our luck, don't lose your temper, okay?" ”

Yu Da still gave face to his senior sister, 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 leave you unable to eat! ”

After saying this, Yu Da walked forward and sat down in his place.

Senior sister breathed a sigh of relief.

When Yu Da came over just now, she stood up, and was about to sit down and continue typing code, but the chair was pulled by Xue Xiyi, and then she sat neatly in front of her computer, tapping the keyboard neatly.

The senior sister was a little worried, afraid that she would not do well, so she stood behind her and watched.

Xue Xi's code was typed very quickly, and it was obvious that she was very familiar with the software they used, and that senior sister only looked at it for a while, and was sure that this senior girl would really optimize the scheme!

When she was about to continue watching, the teacher in front of her saw her standing and couldn't help but shout to her: "Go and help others, don't stand there!" ”

When the senior sister heard this, she couldn't take care of Xue Xi anymore.

After all, the optimization of the firewall does not take effect immediately, she has to help others resist external attacks!

Therefore, this senior sister didn't notice that after Xue Xi left, her eyes narrowed, and she had quietly opened another panel and quickly typed the code on it.

-

Yu Da sat in front of the computer, his face serious.

His fingers were tapping quickly on the keyboard, making people dazzled, and he tapped a few times casually, and the person next to him breathed a sigh of relief: "Fortunately, you came in time, I won't be able to hold it here soon!" ”

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

With Yu Da, everyone breathed a sigh of relief, and couldn't help but start discussing: "It's a person on the other side, right?" Many of us can't resist him alone, it's amazing! ”

"I don't know who it is, I look at the ID like it's from abroad."

"Why did this top hacker hack into our intranet? To be honest, there is no secret on the intranet, but if it is breached, Huaxia University will be very embarrassed. ”

It is a great shame that a century-old university, specializing in cultivating computer talents, was broken into the school's network by one person.

A few people were talking, and suddenly a voice came: "It's over, his attack is even stronger!" Fast! ”

"Oops, I've been breached here!"

"Damn, he was just tempting, this is the real attack, we can't defend at all!"

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

In the tense atmosphere, Yu Da was rapidly tapping on the keyboard, patching various loopholes, and resisting the opponent's attacks.

His face was solemn.

The opponent's attack is strong and sharp and irresistible, he has been in the computer industry for so many years, and only the last time X attacked the school's monitoring system, he encountered such pressure.

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

The other party was obviously a foreigner, but it made him feel a sense of helplessness like a monstrous flood that was about to rush.

It seems that the power of the other party on the network is as irresistible as the power of nature!

Yu Da tapped the keyboard hard, trying to resist the opponent's invulnerable power with his weak body, knowing that this was a mantis arm as a car, but he did not flinch.

His eyes were sharp, and he closed his eyes in despair as he watched the uncontrollable water come overwhelmingly!

Originally, I thought that the network would be completely paralyzed and directly controlled.

Unexpectedly, when I opened my eyes again, there was an invisible barrier to block the flood!

Not breached!

Yuda was stunned.

He stared at the screen, and saw that the opponent's attack was not only not alleviated, but more rapid and domineering, but that barrier was firmly rooted there, giving people an infinite sense of security.

Yes.

Security.

Although it seems to be only a thin layer, it is like Mother Earth stretching out a gentle hand, silently blocking out all dangers.

Who is it?

Who is this person who helped them?!

This gentle but domineering, like a mountain...... It's x!

Chivalry X!

Yu Da's eyes lit up, he had long been a fan of X, and he had a quick look.

X is now fighting foreign hackers, and he can't take care of himself at all.

It was a good opportunity for him to take advantage of the situation.

He didn't want to do anything, he just wanted to find out who Idol X was.

He swallowed, and although he knew it was rude, he rudely tapped the keyboard and searched for X's ID, only to find ...... This ID address...... It's in the machine room!!

After seeing the address of the camera, Yu Da's eyes widened.

This, this is not ......
