After asking this, Han Yingqiu glanced at the paper pressed under Jin Yuxing's hand, and her eyebrows immediately wrinkled. As a student of the Department of Computer Science, Han Yingqiu certainly knows that mathematics and computer theory have many similarities, but early exposure to too advanced theories will only make beginners confused, which is not conducive to systematic learning.

So she said: "This seems to be Professor Su's paper in the Department of Mathematics, will it be more difficult for you to browse it, junior brother?" ”

At this time, Jin Yuxing turned his head and said indifferently: "It's a little difficult to understand, I'm not thinking about it!" ”

Immediately, he stood up, picked up the stack of papers, patted them, and continued to sigh: "Professor Su's mathematical theory is unfathomable, I think I should come back to study it in two years!" ”

After that, Yuxing walked to the borrowing desk and spit out two words at Xie Rui: "Return the book!" ”

Han Yingqiu was stunned by Yuxing's series of words and actions, but she intuitively felt that maybe Yuxing had found what he was looking for in the paper. She really wanted to step forward and snatch the stack of papers to take the school Yuxing, but if she really wanted that, she would be too unreserved.

Just thinking about it, suddenly Xie Rui shouted: "Senior sister, please come over and help take a look, it seems that there is a problem with the computer!" ”

"What's going on?" Han Yingqiu hurriedly came over to take a look, and sure enough, the computer that processed the borrowing records had a jam.

"Let's reboot!" Yuxing crawled on the counter and suggested.

When Xie Rui heard this, he turned his head to look at Han Yingqiu.

"Do as he says!" Han Yingqiu also agreed.

But after restarting, it still freezes.

Yu Xing and Han Yingqiu both frowned, glanced at each other, and said in unison: "I'm afraid it's poisoned!" ”

"Then it's still senior sister, let's take a look!" Xie Rui hurriedly gave way.

Han Yingqiu didn't give in, immediately sat down in front of the computer, tapped the keyboard, and checked the backstage first.

The process manager slowly popped up more than ten seconds after Han Yingqiu pressed the shortcut key, and Yuxing glanced at it and didn't find any extra abnormal processes in it.

You know, the computers that store the borrowing records are directly connected to the library's intranet, but at the moment the machine is not poisoned, but it is so stuck, then there is only one possible surname.

"The campus network of Beijing University may have been hacked!" When Han Yingqiu just judged the reason, Yuxing had already announced it.

Han Yingqiu glanced at Yuxing in surprise, continued to tap on the keyboard, and tried to access the homepage of the campus network.

Unfortunately, the browser returns a message saying: "The service is busy and cannot be accessed!" ”

"Ping under DOS and see if you can connect to the Internet!" Yuxing made another suggestion.

glanced at Yuxing with disgust, and Han Yingqiu immediately did so.

In fact, anyone who claims to be a computer guru hates it when other people point fingers. However, at present, Yuxing's proposal takes the lead everywhere, so that Han Yingqiu has nowhere to sprinkle it.

Ping the IPs of several large portals, but none of them can be linked.

Xie Rui, who was on the side, also saw the problem at this time, this nail was attacked by hackers, she asked, "What should we do now?" ”

At present, there are students here at the borrowing desk who are coming to return the books one after another, and if you don't deal with this matter in time, I'm afraid that there will be trouble in the future!

Han Yingqiu glanced at her face in front of the stage more than at the lively boys, frowned slightly, and said, "Does Brother Jin have any high opinions?" ”

Although Han Yingqiu is a talented woman in the computer department, hacking technology is not her forte, just a rough surface, and she also feels helpless in the face of such a cyber attack.

Yuxing thought for a while and said, "Is there a computer with a better configuration?" In fact, he wanted to ask if there was a separate room for him to work in.

"Yes! In the office inside too! Han Yingqiu said, "I'll take you there, Rui'er, you take care of it first, and write down all the books that have been returned!" ”

Without waiting for Xie Rui, who had a bitter gourd face, to scratch his hair, Han Yingqiu took Yuxing into the office.

After Han Yingqiu entered the system login password, Yuxing said: "Senior sister, please go out too!" ”

"You say I'm... Also go out? Han Yingqiu was extremely embarrassed and stammered and asked.

"yes, I need to be alone for a while!" Yuxing said without doubt.

Han Yingqiu was helpless, glared at Yuxing fiercely, slammed the door and went out.

"This is all of you, otherwise Lao Tzu will open the door and come in by himself, and he won't even need the login password!" Yu Xing secretly locked the door of the office, and then his mental power was instantly released, and he invaded the library's intranet through the computer.

……

"Huh!? Senior sister, why did you come out again? Xie Rui said in surprise.

Han Yingqiu said stiffly: "I'm afraid you're busy, I'll come out to help you!" It's enough to have Jin Yuxing alone! ”

Xie Rui 'sweated' in her heart, and she could hear that Han Yingqiu was gritting her back molars when she said the words 'Jin Yuxing'.

At this time, there was a faint buzz of students downstairs and in the nearby reading room, apparently everyone had discovered the problem of the stuck network and was making a fuss!

In the office, Yuxing already had a layer of white sweat on his forehead.

No way, it's too much calculation.

It's huge, indeed!

Yuxing's spiritual power only extended to the first node gateway connecting to the external network of the campus network of Beijing University, and was shocked by the amazing data flow. Where is this TM hacker invading, dare to send spam messages to the campus network of Beijing University, intending to block the entire network channel.

But after thinking about it, Yuxing felt that something was wrong. After all, the campus intranet of Beijing University can be turned off from the external network connection, but why does this still cause such a situation? Is there an internal annihilation, or something else?

Besides, the channel is blocked, and even if the intrusive party wants to obtain any information, it will be difficult. The other party can't be so stupid, right?

This series of questions lingered in Yuxing's mind, causing his thoughts to be a little disordered.

"Since the other party dares to do this, then he must be ready to be retaliated against, let Lao Tzu give you a little power!" Thinking of this, Yuxing didn't bother to care about these DDOS attacks anymore, but just combined his mental strength in one place and started the action of touching the melons along the vine.

The intruder sends spam data to the Beijing University at the same time with multiple IPs, and each IP has set up multiple springboards, many of which are servers of some large multinational groups, so if ordinary hackers come to conduct anti-tracking, it is difficult to break through these servers with super firewalls. However, all this is not a problem for Yuxing at all, and in the face of Yuxing's strange 'telecommunication spiritual power', any security strategy on the wired network is vulnerable.

Soon, Yuxing found one of the IPs launched by the attack, which came from an IT company near San Francisco.

Didn't say it, kill it!

Yuxing just sent a small instruction to the company on the other side of the ocean through the Internet in the form of brain waves, and within a few tenths of a second, a large number of bad sectors appeared on the hard disks on all the company's computers.

These computer hard drives are like white paper full of pencil drawings, and Yuxing's spiritual power is like countless erasers, wiping these pencil drawings into a mess in just a moment.

However, this was only the beginning of Yuxing's retaliation, and at the same time, the Internet Software Alliance in California also suffered a similar attack, and within two or three seconds, the hard disk array of the auxiliary root server on the 192.5.5.241 IP was all smoked, and then the connection was dropped.

There was a panic in the ICANN building, and phone calls rang one after another. CEO Rhodes sat in his office listening to his report, his eyebrows furrowed, "Could it be that incident exposed?" The other party knocked on the door so quickly? No way! It is absolutely impossible with the Internet technology of the East!"

Soon, the CIA also received the news and began to investigate the ins and outs of this serious hacking incident.

At the same time, parts of the Internet in China have temporarily cut off communications. However, the intranet on the campus of Beijing University was unimpeded in an instant.

"Senior sister, it seems that the intranet is normal again!" Xie Rui had been keeping an eye on the computer, and she soon noticed that it was not as stuck as before.

When Han Yingqiu heard this, she was stunned, then looked at her watch and secretly thought, "It's only been three minutes! Boy, he won't be so godly!"

"Then you hurry up and deal with all the borrowings of these classmates, and I'll go in and have a look!" Cold Autumn Road.

In fact, if it weren't for the cold Yingqiu school flowers in the borrowing desk for the past four or five minutes, I was afraid that the boys around me would have made a fuss. Fortunately, the beauty is delicious, everyone only cares about the cold beauty with their eyes, and I wish this network card would last a little longer!

As soon as he pushed the door, Han Yingqiu found that Yuxing had locked the door from the inside, so he stomped his feet angrily, and then returned to Xie Rui and sat down, sulking there.

Xie Rui skillfully handled the borrowing and returning of each classmate's book, and asked, "Senior sister, what's wrong?" ”

"Nothing!" Han Yingqiu didn't want to answer this question head-on, so she casually took the books returned by a boy and said firmly: "Where's your library card?" ”

The boy was still proud that he had been personally received by Han Daxiaohua, but as soon as he heard Han Yingqiu's cold tone, the whole person immediately withered, and handed over the library card tremblingly, not daring to cross it in the slightest.

At this time, Yuxing walked out of the office tiredly, and said weakly: "Who is that... I remember that I returned Professor Su's paper! I'll go first! After saying this, he didn't even glance at Han Yingqiu, let alone any explanation, so he left like that.

Han Yingqiu wanted to chase after him and beat Yuxing violently, but when he thought of his strength of kicking the sixth stage of the black belt, he lost that courage again. As a result, the boys and girls who came to return the books all felt the vigorous fire of the Han University.

As soon as I returned to the dormitory, I heard Zhang Yi bragging about the Chinese Red Ke vs. the United States hackers.

Seeing Yuxing coming back, he immediately beckoned: "Third child, do you know about the hacker war just now?" ”

Yuxing looked stunned and said, "Where? ”

"Ha-junior, you don't even know this, it's so out, listen to me tell you......"
